The system also includes a wireless footswitch 217 that includes a main footswitch 218, a multi-color LED indicator 219 for signal and battery status, and a reset button 220.

Figure 3 represents the electrical architecture of the first embodiment, in which block (a) contains the electrical design for the wireless foot switch. The foot switch is powered by a battery and is operated by a control logic circuit that processes signals for an electronic signal emitter and receiver (indicated with receiver ES and emitter ES in the Figures). It should be noted that, as used in this Application, the term "electronic signal" includes any means of wireless communication known today or developed in the future, including, but not limited to, Laser, IR, RF and Bluetooth communications. Block (b) illustrates the architecture design for the main control. There is a battery charging section, since the unit is battery powered. The signal is processed through a control logic circuit. The information is entered by means of a touch screen through a graphical user interface. The signal from the foot switch controls the laser emission by sending electronic signals to the system generally. The control program can be updated via a USB port.

Similarly, in Figure 4, where the architecture is for the system of Figure 2, block (a) illustrates the electrical design for the wireless foot switch. The foot switch is battery powered to operate control logic that processes signals for the electronic signal emitter and receivers. Block (b) illustrates the architecture design for the main control. There is a battery charging section, since the control console and handpiece are battery operated. The signal is processed through a control logic circuit. The information is entered by means of a touch screen through a graphical user interface. The control program can be updated via a USB port. Block (c) illustrates the architecture design for a battery-operated handheld instrument. There is an electronic signal sender and receiver in the hand instrument to send / receive signals to and from a main control unit. The information is processed by the control logic circuit to control the laser emission. The laser emission is controlled by a wireless signal from the foot switch.

Both embodiments use a laser module to generate a multi-wavelength laser beam for emission through a single fiber. It should be noted that the laser module is positioned in the console in the first embodiment (Figure 3) and in the hand instrument in the second (Figure 4). Figure 5 depicts a laser module used in both embodiments. The laser module depicted in Figure 5 can be a laser module capable of emitting either a single wavelength, or multiple wavelengths, depending on the types of laser chips used in the module. The laser module is housed in a metal housing 501. Inside the housing 501, a cooling body 502 carries a laser chip 503 and a detector chip 504. The detector chip 504 detects the laser signal so that the emission of laser energy. The laser chip 503 and the detector chip 504 are attached by lead wires 505, 506, 507 respectively to the electrodes 505a, 506a and 507a on the housing 501. In front of the laser chip 504, there is an optical lens 508 to make the beam of emitted laser is transformed into a parallel beam 509 for transport.

Another cooling body 510 carries a laser chip 511 and a detector chip 512. The laser chip and detector chip are attached by lead wires 513, 514, and 515 to electrodes 513a, 514a, and 515a respectively. There is an optical lens 516 to make the emitted laser beam transform into a parallel beam 517. Both beams 509 and 517 meet a filter / reflector 518 that is 100% transparent to beam 509 and 100% reflective to beam 517, reflecting beam 517 to create beam 517a. The reflectance and transparency of this filter / reflector 518 is due to the fact that one side of the filter / reflector 518 is transparent to all or at least most wavelengths of laser light while the other is reflective to all or to most wavelengths of laser light.

Still another cooling body 519 carries a laser chip 520 and a detector chip 521. The laser chip and detector chip are attached via lead wires 522, 523, and 524 to electrodes 522a, 523a, and 524a respectively. There is an optical lens 525 to make the emitted laser beam transform into a parallel beam 526. Beams 526, 509, 517a meet a filter / reflector 527 that is 100% transparent to beams 509 and 517a and 100% reflective to beam 526, reflecting beam 526 to create beam 526a. The three

ES 2 551 019 T3 beams 509, 517a, 526a reach an optical lens 528 housed by bracket 529. Lens 528 focuses all three beams onto a single fiber 530. Thus, with three generated laser beams combined into a single beam , the fiber can emit a single laser beam with three different wavelengths. It is conceivable that additional laser sources could be used to add more wavelengths to the final emitted beam.

Delivering a laser beam to a surgical surface is key to the laser system. Various laser beam delivery mechanisms will be described in this document.

Figure 6 (a) depicts one of the delivery mechanisms for a laser beam. Given a laser module 6001 as described in Figure 5, the system according to the present invention is then assembled with the laser module 6001 as a centerpiece, shown in Figure 6 (a). A 6002 fiber exits module 6001 to connect to other components. A clamp 6003 is provided to fiber 6002 in order to connect the fiber

6002 to the next stage. A nut 6004 attached to the clamp 6003 makes it easy to attach the clamp

6003 to other connections. Fiber 6002 is terminated at the 6005 end of the clamp with a standard fiber termination. Then, there is a housing 6007 with an opening 6008 at the proximal end and another opening 6009 at the distal end. There are precision spacers 6010 and 6011 at both ends of an optical lens 6012, inside housing 6007. Details for housing 6007 will be described in Figure 6 (b). A 6013 connector is provided for additional light transport. Connector 6013 with an opening 6014 at the proximal end and an opening 6015 at the distal end, and a stop point 6016, contains the housing 6007. Then, a clamp 6017 contains another fiber 6018. A nut 6019 is connected to the clamp 6017 for your union. Fiber 6018 has a standard 6020 termination on the 6017 end. At the other end of the 6018 fiber, there is a 6021 clamp to make the fiber connect to the next stage. A nut 6022 is attached to the clamp 6021 and there is a fiber termination surface 6023 at the end of the clamp 6020. Another housing 6024 with an opening 6025 at the proximal end and an opening 6026 at the distal end contains a precision spacer. 6027 and 6028 at both ends of a 6028 optical lens, respectively. A 6030 connector with a 6031 opening at the proximal end, a 6032 opening at the distal end, and a 6033 stop point, contains the 6024 housing. Another 6034 clamp to contain 6035 fiber with a 6036 fiber termination can fit the 6030 connector. .

Figure 6 (b) depicts details of housing 6007 and 6024. A cylindrical housing 6101, which may be made of metal or plastic with elastic properties, has an opening 6102 at the proximal end, an opening 6103 at the distal end, and an open slot 6104 from the proximal end to the distal end. The important feature is the open slot 6104 to allow any clamp with a size larger than the inside diameter of the 6101 casing to be inserted from both ends, and the clamp is automatically aligned. It is important to adapt the variation of the clamp, so that it is in precise relation to each of the others.

Figure 6 (c) represents the fiber driving mechanism assembled as a schematic of Figure 6 (a). A laser beam from the 6201 laser module is carried through a 6202 fiber cable to a 6203 connection point, which contains a connector, a housing with a lens and spacers, and a clamp for another 6204 fiber. The beam Laser is coupled from one fiber to another fiber using 6203 connection points. The mechanism of the connector, spacers and lenses makes the efficiency of coupling one fiber to another fiber optimal. The 6203 connection can be the transport point for transporting the laser beam from inside the laser system to the outside of the laser system, as depicted in Figure 1 and Figure 2. The laser beam is then transported to another connection point 6205, contains a connector, a housing with another lens and spacers, and a clamp for another fiber 6206, which can deliver the laser beam to the surgical surface. The 6205 connection point can also be the transport point from the handpiece to the replaceable tip for the laser system, as described in Figure 1 and Figure 2.

Figure 6 (d) represents the optical system for transporting the laser described in Figure 6 (a). A 6301 laser beam is fed into a 6302 fiber, then it leaves the 6302 fiber, then it is focused by the 6303 lens towards another 6304 fiber, then it leaves the 6304 fiber, then it is focused by the 6305 lens towards another 6306 fiber, and finally exits the end of the fiber 6306 as a bundle 6307 to an application surface.

The laser beam delivery mechanism depicted in Figure 6 (d) can be used by a laser system with a power output range of 1 to 10 watts.

Figure 6 (e) depicts another of the delivery mechanisms for a laser beam. Given a 6401 laser module as described above, the system according to the present invention is then coupled with the 6401 laser module as a centerpiece, shown in Figure 6 (e). Fiber 6402 exits module 6401 to connect to other components. A clamp 6403 is provided to fiber 6402 in order to connect fiber 6402 to the next stage. A nut 6404 connected to clamp 6403 facilitates connection of clamp 6403 to other connections. Fiber 6402 is terminated at the end of clamp 6405. Next, there is a housing 6406 with an opening 6407 at the proximal end and another opening 6408 at the distal end. There is a precision separator 6409, an optical lens 6410, and another precision separator 6411 inside the housing 6406. The housing 6406 is identical to the housing 6007 described in Figure 6 (b). A 6413 connector is provided for additional light transport. Connector 6413 has an opening 6412 at the proximal end and an opening 6414 at the

ES 2 551 019 T3 distal end. At the same time as housing 6406 is inserted into connector 6413 at proximal end 6412, an identical housing 6415 is inserted in the same manner into distal end of connector 6414. The structure within housing 6415 reflects the structure in housing 6406 since it contains a precision spacer 6418, an optical lens 6419 and another precision spacer 6420 inside the housing 6415. The housing 6415 also has a proximal opening 6416 and a distal opening 6417. The distal opening 6417 receives a clamp 6422 containing a fiber 6421, which is terminated at the end of the clamp 6424. The clamp 6422 is attached, in the same way, to a 6423 nut to facilitate connection. This is the first part of the 6421 patch fiber, which has an identical structure at its other end; specifically, there is a 6425 clamp to make the fiber connect to the next stage. A nut 6426 is attached to clamp 6425 and to a fiber termination surface 6427 at the end of clamp 6425. Another 6428 housing with a 6429 opening at the proximal end and a 6430 opening at the distal end contains a 6431 precision spacer, 6432 lens, and 6433 precision spacer. A 6434 connector with a 6435 opening at the proximal end, an aperture 6436 at the distal end, and a 6437 stop point for the 6428 housing. Another 6439 clamp to contain 6438 fiber with a 6440 fiber termination can fit onto the 6434 connector. This construction has the added utility of an extra focusing lens over the first embodiment described in Figure 6 (a).

Figure 6 (f) represents the fiber conduction mechanism as a schematic of Figure 6 (e). A laser beam from laser module 6501 is carried through a fiber cable 6502 to a connection point 6503, which contains a connector, a housing with two lenses and a clamp for another fiber 6504. The 6503 connection point can also be a transport point to transport the laser beam from inside the system to the outside of the system, as described in Figure 1 and Figure 2. The laser beam is then transported to Another 6505 connection point contains a connector, a housing with a lens and a clamp for another 6506 fiber, which can deliver the laser beam to the surgical surface. The 6506 connection point can be the transport point from the handpiece to the replaceable tip for the laser system, as described in Figure 1 and Figure 2.

Figure 6 (g) represents the optical system for transporting the laser described in Figure 6 (e). A 6601 laser beam is fed into a 6602 fiber, then exits the 6602 fiber, then is focused by 6603 and 6604 lenses onto another 6605 fiber, then exits the 6605 fiber, then is focused by the 6606 lens onto another 6607 fiber , and finally exits the end 6607 as a beam 6608 towards an application surface.

The laser beam delivery system depicted in Figure 6 (g) can be used for a laser system with moderate power output; for example, the final laser output is in the range of 1 to 15 watts.

Figure 6 (h) depicts another of the delivery mechanisms for a laser beam. Given a 6701 laser module as described above, the system according to the present invention is then assembled with the laser module

6701 as a centerpiece, as shown in Figure 6 (h). Fiber 6702 exits module 6701 to connect to other components. A 6703 clamp is provided to the 6702 fiber in order to connect the fiber

6702 to the next stage. A 6704 nut attached to the 6703 clamp makes it easy to attach the clamp

6703 to other connections. The fiber 6702 is terminated at the end of the clamp 6705. Next, there is a housing 6706 with an opening 6707 at the proximal end and another opening 6708 at the distal end. There is a 6709 precision spacer, 6710 optical lens, and 6711 precision spacer within housing 6706. Housing 6706 is identical to housing 6007 described in Figure 6 (b). A 6713 connector is provided for additional light transport. Connector 6713 has an opening 6712 at the proximal end and an opening 6714 at the distal end. At the same time that housing 6706 is inserted into connector 6713 at proximal end 6712, in the same manner a housing 6715 is inserted into connector distal end 6714. The structure inside the 6715 housing mirrors the structure in the 6706 housing as it contains a 6718 precision spacer, a 6719 optical lens, and another 2720 precision spacer inside the 6715 housing. The 6715 housing also features a proximal opening 6716 and a distal opening 6717. The distal opening 6717 receives a clamp 6722 containing a fiber 6721, which is terminated at the end of clamp 6724. Clamp 6722 is likewise attached to nut 6723 to facilitate connection. This is the first part of the 6721 patch fiber, which has an identical structure at its other end; specifically, there is a 6725 clamp to make the fiber connect to the next stage. A nut 6726 is attached to the clamp 6725 and to a fiber termination surface 6727 at the end of the clamp 6725. Another 6728 housing with an aperture 6729 at the proximal end and an aperture 6733 at the distal end contains a 6430 precision spacer, 6431 lens, and 6432 precision spacer. A 6734 connector is provided for additional light transport. Connector 6734 has an opening 6735 at the proximal end and an opening 6736 at the distal end. As housing 6728 is inserted into connector 6734 at proximal end 6735, in the same manner an identical housing 6737 is inserted into connector distal end 6736. The structure inside housing 6737 reflects the structure in the 6728 housing as the housing contains a 6738 precision spacer, 6740 optical lens, and another 6741 precision spacer inside the 6737 casing. Housing 6737 also features a proximal aperture 6738 and a distal aperture 6742. The distal aperture 6742 receives a clamp 6743 that contains a fiber 6744, which is terminated at the end of the clamp 6745. This construction has the added utility of two lenses. Extra focus on the first embodiment described in Figure 6 (a).

ES 2 551 019 T3

Figure 6 (i) represents the fiber conduction mechanism assembled as a diagram of Figure 6 (h). A laser beam from the 6801 laser module is carried through a 6802 fiber cable to a 6803 connection point, which contains a connector, a housing with two lenses, spacers between lenses and fiber terminations, and a clamp for other fiber 6804. The laser beam is then transported to another connection point 6805, it contains a connector, a housing with two lenses and a clamp for another fiber 6806.

Figure 6 (j) represents the optical system for transporting the laser described in Figure 6 (h). A 6901 laser beam is fed into a 6902 fiber, then exits the 6902 fiber, then is focused by 6903 and 6904 lenses onto another 6905 fiber, then exits the 6905 fiber, then is focused by 6906 and 6907 lenses toward another fiber 6608, and finally exits the end of fiber 6608 as a bundle 6609 to an application surface. The mechanism designed in Figure 6 (j) can be useful for a high power laser supply.

Thanks to the fiber coupling design of Figures 6 (a) - 6 (j), the fiber tips for surgical purposes can be changed at any given time. A tip design with a housing and an optical lens is illustrated in Figure 7a. The tip comprises a sheath 701 from which a hollow tip 702 extends. In the hollow tip 702 there is a channel 703 to guide the fiber 708. A cylindrical housing 706 contains an optical lens 705, a spacer 704, and a fiber connector 707 that surrounds one end of the fiber 708. The fiber 708 will bend into the shape of the channel 703 which can be straight or at any angle. There is an open space 709 such that the tip can be fitted to the designated handpiece.

The tip shown in Figure 7b is a tip without an optical lens. The tip comprises a sheath 710 from which a hollow tip 711 extends. In the hollow tip 711 there is a channel 712 to guide the fiber 714. There is a connector 713 that surrounds the fiber 714 within the tip sheath 710. The tip cannular 711 can be at any angle by designing the sheath such that the fiber can be at any angle relative to the axis of the tip.

There is a space 715 to have the tip to be attached to the handpiece. In any of the tip embodiments, the fiber at the tip can be versatile and can emit light in different patterns through the physical structure of the tip, as is known in the art and shown later, including right at the tip. from the tip or in all directions. The structure of the tip is such that the fiber 708, 714 is held fixedly at the tip, with the intention of being disposable, while sacrificing as few material resources as possible. Being fixed at the tip and being disposable, it does not undergo the same stresses as in the other fibers of the prior art and can be gently bent to any angle during assembly with little fear of fatigue and tension caused by repeated insertion and removal of the fibers. in other cannula systems.

The tips can be deflected at any angle from an axis defined by the fiber connectors on the tip. Figures 8a - 8e represent the tip design of Figure 7b with deviations of 0 °, 30 °, 45 °, 60 ° and 90 ° respectively. Those angles are, of course, examples since any angle can be used since the envelope of each tip supports the fiber and the fiber does not fatigue from being repeatedly bent by various degrees when inserted and removed from a cannula or other guide. Each tip has an 801a, 801b wrap, etc. with a cannular tip 802a, 802b, etc. that extends from these. A barrel connector 804a, 804b, etc. surrounds one end of fiber 805a, 805b, etc. and is located opposite the hollow point 802a, 802b, etc. of the housing 801a, 801b, etc. This is surrounded by a space 806a, 806b, etc. to enable connection to the handpiece. The barrel connector 804a, 804b, etc. also defines an axis. Each hollow point 802a, 802b, etc. contains a channel 803a, 803b, etc. and is bent (as well as the contained channel 803a, 803b, etc.) to an angle with respect to the axis. A fiber 805a, 805b, etc. extends from cylindrical connector 804a, 804b, etc. through channel 803a, 803b, etc. and its distal end extends outward from the hollow tip 802a, 802b, etc. following the angle of the tip, thereby redirecting the received laser from the connected handpiece.

Although the present invention has been described with reference to preferred embodiments, numerous modifications and variations can be made and the result will still be within the scope of the invention.
