Description

Direct-view Wicresoft radiography pincers

Technical field

This utility model relates to a kind of radiography pincers, and particularly a kind of direct-view Wicresoft radiography clamps, and it is exclusively used in separation, shaping and the mediation of inside of human body biliary tract, 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,, need operative treatment in case in the human body body, find the gallbladder focus, in the treatment journey of performing the operation, biliary tract needs separation, shaping and mediation, prior art: the one, in operation process, need in the human body body, carry out pneumoperitoneum, and make operation that certain space be arranged; The 2nd, with general pincers and cutter carry out that biliary tract needs to separate, shaping and mediation; 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, general pincers and cutter, biliary tract is fragile, does 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 provides a kind of reasonable in design, wound little direct-view Wicresoft radiography pincers.

The technical scheme that its technical problem that solves this utility model adopts is: these direct-view Wicresoft radiography pincers comprise fixed handle, flexible handle, pull bar, draw-bar seat, claw beam, clamp, connecting plate, clamp seat, rotator, bearing holder (housing, cover), bearing block, fixture block and irrigator, have the radiography groove on the clamp, it is characterized in that: also be provided with clamp, jump ring and bayonet lock, described clamp is installed on the flexible handle by bayonet lock, one end of jump ring is fixed by screw and flexible handle, and clamp is provided with latch.

Latch described in the utility model and fixed handle are complementary.

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.Simultaneously, effective, easy to use, the operation safety of radiography.
