Description

Direct-view Wicresoft curved scissors cutter

Technical field

This utility model relates to a kind of shears, particularly a kind of direct-view Wicresoft curved scissors cutter, and it is applicable to Wicresoft's human body operation, is particularly useful for human internal organs is separated, and belongs to medical instruments field.

Background technology

Traditional surgical operation generally all will cut otch one on patient's skin and flesh, short then 6-10 centimetre, long then 10-15 centimetre or longer.In operation process, in case in the human body body, find focus, need excision, in inadvertent closure, intracorporeal organ need be searched lesions position, in search procedure, intracorporeal organ needs to separate, and prior art is to carry out pneumoperitoneum in the human body body, makes operation that certain space be arranged, cut with scalpel, intracorporeal organ is separated.Its defective is usefulness pneumoperitoneum operation, and operating time is long, and it is slow that patient feels bad wound healing, if the weak wound healing effect of patient body is just poorer; The 2nd, cut with scalpel, intracorporeal organ is separated, easily hurt other organs, do not satisfy ideal surgical effect.

Summary of the invention

The purpose of this utility model is to overcome existing the problems referred to above in the prior art, and a kind of reasonable in design, direct-view Wicresoft curved scissors cutter that wound is little are provided.

The technical scheme that its technical problem that solves this utility model adopts is: this direct-view Wicresoft curved scissors cutter comprises fixed handle, flexible handle, movable blade, dead knife, pull bar and claw beam, it is characterized in that: also be provided with back-moving spring, rest pad, pull rod slot, draw-bar seat, bearing holder (housing, cover), bearing block, fixture block, rotator and irrigator, described back-moving spring is installed between fixed handle and the flexible handle, rest pad and fixed handle fuse, and pull rod slot is opened on flexible handle; One end of described pull bar is connected with movable blade, and the other end and draw-bar seat are fixed; Draw-bar seat is inserted in pull rod slot and coincide fixingly, and an end of fixture block snaps in bearing holder (housing, cover) and fixes, and the other end is fixed on the rest pad; Rotator and claw beam are connected and fixed, and irrigator is connected with rot, and have flushing hole on this irrigator.

Back-moving spring described in the utility model has two, and they compress mutually, and is fixed on described fixed handle and the flexible handle with steady pin respectively.

This utility model compared with prior art its beneficial effect is: reasonable in design, only need to cut 2-3 centimetre, use special-purpose drag hook that otch is stretched, the cold light source light beam is focused in the human body body by light guide bundles, both can make operative doctor clearly directly see each position in the body clearly, and lower infected danger again because of otch is little; Result of use is good, the safety easy to use of performing the operation.
