Cystoscope.

Application filed March 27. 1913, Serial No. 757,145.

To all whom it may concern:

Be it known that 1, Reinhold H. Wappler, a citizen of the United States, residing at New York city, county and State of New 5 York, have invented a new and Improved Cystoscope, of which the following is a specification.

This invention relates to a cystoscope and more particularly to novel means for clip10 ping and securely withdrawing diseased portions from the inner human organs into which the cystoscope has been introduced. These means comprise essentially a novel nipping device composed of a pair of cup15 shaped tongs or nipping members which may be securely guided toward the point to be operated upon, and other novel features more fully pointed out in the annexed specification and claims.

Tn the accompanying drawing: Figure 1 is a side view of a cystoscope embodying my invention showing the nippers open; Fig. 2 a side view partly in section of the nippers and the means for operating the 25 same, showing the nippers closed; Fig. 3 an enlarged longitudinal section through part of Fig. 2, and Fig. 4 a detail of the nipperS.

My improved cystoscope comprises essen30 tially an outer tube 10 haying a bent fenestrated end: 11 through which an incandescent lamp is exposed that receives current in any suitable manner. Into tube 10 is removably fitted a lens tube 12 having an 35 ocular 13 and an offset collar 14 that is adapted to be slid into a corresponding head 15 of tube 10. Into collar 14 is fitted a bent tubular guide 16 adapted for the passage of a flexible shaft 17 that extends also through 40 tube 10 and projects outward through the lateral object-lens opening 18 of such tube, whereby the angle of the protruding end of shaft 17 may be controlled through a deflector 19, the inclination of which is regu45 lable at will by manipulating knob 20, all as usual and not forming part of the present invention. . .

The flexible shaft 17 comprises essentially a closely wound spiral wire 21, one end of 50 which is tightly fitted into a socket 22 while its other end is seated within a flanged tube 23, the joint between the parts 21, 23 being protected by an outer wire spiral 24. Socket 22 is provided with a threaded flange 25 55 upon which is screwed a sleeve 26, the free / end portion, of which is provided with a transverse slot 27. Within the latter are accommodated the tail ends of a pair of toggle levers 28 pivoted at 29 to sleeve 26. Hie outer ends of levers 28 are shown to βΦ carry opposed hollow semiglobular nipping members 30 having circular cutting edges 31. The tail ends of levers 28 are by togglelinks 32 connected to a socket 33, into a longitudinal bore 34 of which is soldered or βδ otherwise secured a flexible wire rod 35 accommodated within spiral 21. At its other end, wire 35 is secured to a threaded socket 36 carrying an adjusting nut 37. Socket 36 is loosely received within a sleeve 38, the 70 outer end of which carries a fixed head 39, against which nut 37 is adapted to be tightened, a clamp screw 40 passing through head 39 and sleeve 38 serving to maintain socket 36 in the position to which it has 7& been set. The free end of sleeve 38 is loosely received within an enlarged bore 41 o^tube 23. The outer end 42 of the latter is telescoped by a head 43 abutting against the tube-flange 44 and secured against disen- so gagement from the tube by a clamp screw . 45 engaging a circumferential groove 46 of tube section 42. Intermediate head 39 and tube section 42, sleeve 38 is surrounded by a coiled spring 47 that tends to withdraw 35 head 39 from tube 23 and head 43, and thus exercises a pull on wire 35 to close nippers 30. The power with which the latter are forced toward each other may be adjusted by correspondingly manipulating nut 37 fi® after clamp screw 40 has been loosened, which is retightened after such adjustment of spring 47 has taken place. By moving head 39 toward head 43 against the action of spring 47, the corresponding inward movement of wire 35 will spread toggles 32, 28 and thus open nippers 30. For operating heads 39, 43, a pair of scissor-handles 4& are used that are pivotally connected at 49, one of said handles being fulcrumed to a 103 lug 50 of bead 43, while the other handle is fulcrumed to a lug 51 formed on a ring 52 that is secured to head 39 by a clamp screw 53, such clamp screw engaging a circumferential groove 54 of said last named 1Φ8 head. It will be seen that by slightly loosening screws 45 and 53, the handles 48 may be jointly turned relatively to the cutting edges 31 of nippers 30 so as to suit the convenience of the operator, whereupon said 11® clamp screws are again tightened. For effectively dosing the cystoscope after the in

troduction of the clippers, an elastic cap 55 carried by tube 23 is slipped over the bulged end 56 of guide 15.

It will be seen that my cystoscope is pro5 vided with novel and effective means for nipping off or severing parts of tumors, papillomata or other diseased growths from the bladder, etc., the construction being such that after such nipping operation, the sev10 ered parts or nips will be entrapped within the pocket formed by the hollow nipping members, and may thus be safely withdrawn together with lens tube 12, from tube 10 for removal, diagnosis or other purposes.
