Orthosis

p0001The invention relates to an orthosis having a trained for contact with the body of an orthesis dimensionally stable base plate.

p0002Such orthoses are known in numerous embodiments. The base plate can serve each plate rests flat by suitable fasteners to the body of the orthosis wearer. In one embodiment, there is a ventral base plate at the waist, with a fastening strap spans the body in this waist region. In this case, a dorsal back pad may be provided which is overlapped by the fastening belt or comprises the attachment means for the respective ends of the fastening belt, so that the fastening strap spans the body together with the back pad.

p0003A main field of application of such a brace is a hyperextension, protrudes in from the base plate in the vertical direction, ie upwards and / or downwards at least one further away Stützpelotte stably connected to the base plate i st. For a complete hyperextension interacts with the back pad anteriorly along an upper sternal pad and a lower symphysis to form a three-point support. The base plate essentially has the function to act as a fastener for the fastening belt and the two ventral pads. Such hyperextension for example by<patcit id="pcit0001" dnum="DE3928628C1"><text>DE 39 28 628 C1</text></patcit> known. Such orthoses are available in various sizes to allow by differently sized base plates to adapt to the body size and a comfortable fit of the orthosis. With a too narrow base plate fastening straps would greatly cut into the patient's tissue, while too broad a base plate would lead to an unsafe seat. In the known orthoses is the base plate, as well as the pads, made of a metal part, which is provided with a foam pad. therefore must be kept in stock different sized base plates for the formation of the different sizes of the orthosis.

p0004By <patcit id="pcit0002" dnum="US4976257A"><text>US 4,976,257</text></patcit> is a hyperextension known in which a base plate on vertical arms is formed into a sternal and a Lymphysenpelotte. The base plate consists of a flat hard outer plastic which is connected towards the body with a cushioning layer. In the area of ​​sternal the base plate may be provided with a mounting aperture through which a separate cushion plate as sternal pad attachable. The cushion plate is not arranged in alignment with the base plate, but is offset towards the body fixed relative to the base plate. The pad member serve as a single contact surface of the sternal pad.

p0005The present invention has for its object, an orthosis in such a way that it enables improved handling and warehousing.

p0006This object is achieved with an orthosis of the type described above in that the base plate has a neck with a fastening device having at least one side, in alignment with the at the approach, a base plate magnifying extension piece with the approach of the base plate to the rigid connection of the base plate is attached to the extension piece.

p0007In the orthosis according to the invention therefore, the base plate can be increased by attaching of extension pieces, so that depending on whether the base plate no extension or one, two or three extension pieces etc. are mounted, the adjustment of the base plate to the body shape or to the respective required function the orthosis can be realized without different base plates would be required for each size realized. Assigns the base plate, for example, in the width direction, on both sides ends of körperumspannenden, adjustable fastening belt on the extension pieces used by broadening the base plate for adaptation to the respective body size. The compound according to the invention produced between the base plate and the next extension pieces is also dimensionally stable and therefore enters the tensile force of the fastening strap the required shape stability against in order to prevent an undesirable deep cutting of the fastening strap in the patient's tissue.

p0008It is the formation of several different sizes of the resulting base plate expedient if the extension piece is also provided at its free edge with a fastening device for the positive connection with another dimensionally stable extension piece to increase the base plate. In this way, the aforementioned multiple stepped enlargements can be realized.

p0009In an expedient embodiment of the invention, the fastening device has a shoulder with a stepped recess and engages under the attached extension piece the stepped recess with a corresponding stepped recess to form a partial surface contact between the preparation and the extension piece, in approach towards a stop of the extension piece at a stop the approach applied. In this way a very rigid connection enables the connection is rigid by the surface contact of the extension piece on the attachment of the base plate. The stiffness of the connection is not contrary to that the connection between the base plate and extension piece and / or between extension pieces to adapt to the body shape of the orthosis wearer through a limited angle may be tiltable or that the end pieces have a certain elasticity, so that, for example, by the traction of a fastening belt can be used on the body, the deformation, however, a sufficiently large resistance to oppose to not excessively pressed into the fabric of the orthosis wearer.

p0010Preferably in the assembled state of the extension piece engages a vertically arranged in the area of ​​surface contact lock pin into a corresponding recess for forming one of the form-locking connection in the width direction. It is expedient if the vertically arranged for surface contact locking pin in the recess is relatively inserted in the recognition by a tilting movement of the extension piece, wherein the locking pin can be configured latched into the recess. In this way achieves a stable compound realisiserbar by simply attaching and locking the extension piece to the appropriate approach to the base plate or a previous extension piece.

p0011For the formation of the orthosis preferably the base plate bears in the vertical direction at least an attached cap. Preferred is the use of the orthosis according to the invention as hyperextension with a symphysis and sternal pad. Preferably both the sternal pad and the symphysis are adjustable in height attached to the base plate. These preferably is a track of two pipes formed, which is attached to a U-shaped end in the material of the pad. The height is adjusted by shifting the tubes with the pad and by appropriate suitable fasteners of the base plate.

p0012As enlargeable by extension pieces baseplate numerous flat against the body of the orthosis wearer adjacent support plates come into consideration, in particular, the back board of hyperextension. This may be enlarged by extension pieces in a preferred embodiment, also in width. But it can also be formed at different heights, in the extension pieces having the width of the back board are recognized to increase the length of the back board in the vertical direction and thus to develop different long support of the spine.

p0013The orthosis according to the invention preferably has a base plate which is completely formed as an injection-molded plastic part. Correspondingly, the extension pieces sprayed massive plastic parts, preferably without metal reinforcements.

p0014The invention will be explained in more detail below with reference to an embodiment shown in the drawing.

p0015The perspective view of the <figref idrefs="f0001">figure 1</figref> a hyperextension can a ventral base plate 1 recognize to which 2 and connect totaling upward a sternal pad down a symphysis. 3 The height position of the sternal pad 2 can be adjusted by changing the sternal pad 2 mounted on a rail arrangement formed by two tubes 4 and is movable relative to the base plate. 1 The base plate 1 has a locking screw 4 'for fixing the associated with the sternal 2 pipes 4 in a desired height position. Correspondingly, the symphysis 3 is also mounted vertically adjustable on a rail assembly, which is formed by two parallel, with a locking screw 5 'fixable tubes. 5 The two each extending parallel tubes 4, 5 are obtained as legs of a U-shaped tube, the U-shaped end of the assembly is mounted in the respective pad 2; 3.

p0016The base plate 1 has two mutually facing away approaches 6 widthwise. These approaches 6 toothed belt 9 are fixed. One to wrap the body of a patient at the waist provided fastening strap 7 has on its end a rigidly mounted closure. 8 The shutter 8 can be slid to different positions on the toothed belt 9, depending on the needs of the patient in order to build different hoop stresses.

p0017At the orthosis includes a back board 10 through which the fastening strap 7 is pressed against the patient's back in the thoracic and lumbar region.

p0018To adapt the orthosis to different waist circumferences an extension piece 11 is placed on the neck 6 of the base plate 1, which is designed with a the approach 6 respective neck 12, so that the extension piece 11 a further extension 11 is so placed. In which, in<figref idrefs="f0001">figure 1</figref> Illustrated embodiment, three extension pieces 11 placed on both sides of the base plate - are positively connected to each other and cause a dimensionally stable widening of the base plate 1 - in detail below manner explained. The last extension piece 11 is formed as an end cap 11 ', which is formed on the distal surface with a groove-like guide 13 for guiding the fastening strap. 7

p0019The <figref idrefs="f0002">Figures 2 to 6</figref> illustrate the structural design of the base plate 1 and the (same) extension pieces 11. The <figref idrefs="f0002">Figures 2 and 3</figref> show a perspective view of the distal sides of the base plate 1 and an extension piece 11. The base plate 1 has the lugs 6 outwardly open groove-shaped recesses 14, in which, the fastening of the ends of the fixing belt 7 by means of an associated lock eighth The lugs 6 taper in width conically outwardly and terminate at an edge 15, which forms a stop. Below, so proximally from, the edge 15 extends a tongue 16 in the width direction across the edge 15 addition.

p0020<figref idrefs="f0002">figure 4</figref> shows that the tongue 16 continues to the proximal side of a portion 17 of the lug. 6 The extension 17 rises on the proximal side stepped out of the material of the neck 6, so that a step-shaped recess 18 is in the vertical direction on both sides of the section 17, is stepped with respect to the surface of the portion 17 recessed contact surface 19 formed by a both sides of the section 17th From the contact surface 19 in each case a locking pin 20 rises.

p0021The extension piece 11 comprises a fork-shaped end formed, the recess 21 is formed with a contour corresponding to the outer contour of the tongue sixteenth The recess 21 is delimited by two webs 22 which have on their distal surface a stepped transition line 23, whose profile corresponds to the profile of the step-shaped junction 18 of the extension 6, is thus complementary. By the stepped transition 23 has each land 22 has a step-shaped recessed bearing surface 24, which is formed for engagement with the corresponding abutment surface nineteenth The contact surface 24 is provided with a through hole 25 for receiving the locking pin 20th The legs 22 are connected to each other beyond the recess 21 by a base body 26 having a groove-shaped recess 27 has on its distal upper surface in the width direction and serving as a guide for the fastening strap 7th

p0022As <figref idrefs="f0002">figure 4</figref> illustrates the basic body has on its proximal side a central stepped recess 28 which serves to accommodate the standing on the stop edge 15 beyond the tongue 16 of the attachment. 6 The tongue 16 is provided with a locking cam 29 which engages in a corresponding recess 30 in the step-shaped recess 28 in the assembled state.

p0023<figref idrefs="f0002">figure 4</figref> clarifies further that the base body 26 of the extension piece 11 is provided in a manner corresponding to the neck 6 with a fastening device from contact surface 19 and locking pin 20 and a tongue 16, so that the extension body 11 can be latched with a further extension of the body 11 in the same way.

p0024<figref idrefs="f0002">figure 3</figref> illustrates that the locking of the extension body 11 is carried on the shoulder 6 of the base plate 1 in that the extension piece 11 is tilted in proximal and approached in this position to approach 6 so that the contact surface 24 of the contact surface 19 opposite The stop edge is 15 of approach on a corresponding stop edge 31 of the base body 26th By tilting back of the extension piece 11 to the alignment with the approach 6 position engage the locking pins 20 in the openings 25 of the extension piece 11 a. At the same time there is an engagement of the locking cam 29 of the tongue 16 in the recess 30 of the stepped recess 28 of the extension piece 11. The two latches may be designed as latching, so that a form-fitting in the width direction connection is established both by the locking pins 20 as well as over the locking cams 29 , By appropriate dimensioning, for example, the locking cam 29 and recess 30, the connection can a perpendicular to the width direction axis through a limited angle tilted and / or elastically be carried out, thereby automatically adapt to the build of the orthesis is made. In the pulling direction of the fastening strap 7 is also a dimensionally stable connection due to the interlocking adjacent contact surfaces 19, 24 on both sides (in the vertical direction) of the approach. 6

p0025<figref idrefs="f0002">figure 5</figref> clarifies the approach of the extension piece 11 to the mounting position and <figref idrefs="f0002">figure 6</figref> the after tilting back with the neck 6 of the base plate 1 in alignment scheduled a positive and dimensionally stable manner extension 11th

p0026<figref idrefs="f0002">figure 6</figref> also reveals that of the extension piece 11 another equally trained extension piece can be attached in the same way, so that in <figref idrefs="f0001">figure 1</figref> configuration shown with a widened by three extension pieces 11 base part 1 can be produced readily.

p0027<figref idrefs="f0003">figure 7</figref> shows a second embodiment of an orthosis according to the invention, which is designed as a hyperextension orthosis. It differs from the first embodiment, in the<figref idrefs="f0001">figure 1</figref> is shown, characterized in that the back pad 10 has a fastening device for fastening of appendixes 11, so that the width of the back board 10 is adjustable in the same manner as the width of the ventral base plate first

p0028This in <figref idrefs="f0004">figure 8</figref> third embodiment shown includes compared to the first embodiment of the <figref idrefs="f0001">figure 1</figref> the modification that the back board 110 is formed as a resizable in height toward the base plate. For this purpose, the back board 110 extension parts 111 be attached which extend over the entire width of the back board 110th In this manner, a support of the spinal column is adjustable over which length is performed by the back board 110th In this embodiment, it is of particular importance that the extension pieces 111 are 110 and relative to each other is formed relative to the base part of the back board to a limited angular tilting so that the adjustment can be made to the contour of the spinal column, and yet the support required is ensured. Similar to the side of the widening caused by at least one extension piece 111 extension is closed by an end piece 111 '.

p0029It is of course also conceivable for the width-adjustable back pad 10, as in <figref idrefs="f0003">figure 7</figref> is shown to combine with the enlargeable in the vertical direction back board 110, so that the back board can be enlarged by extension pieces 11, 111 both in the width direction and in the vertical direction.
