Description
Technical field
This utility model relates to a kind of open operation and pulls the gram pincers, belongs to technical field of medical instruments.
Background technology
During open operation is performed the operation in human body, sometimes need intestinal tissue in the body is drawn and dissociates, be convenient to operative site the operation that undergos surgery of enough spaces is arranged, prior art does not have special-purpose apparatus forceps class, can only substitute with common hoe scaler class, the large intestine nipper that the usefulness that also has is general, its defective is: it is sharp that general hoe scaler and large intestine nipper clamp press from both sides tooth firmly, clamp is nonelastic, in the traction of intestinal tissue and free process, easily cause the organ-tissue damage, do not satisfy ideal surgical effect.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of reasonable in design is provided, and the traction and the free open operation that are exclusively used in intestinal tissue are pulled the gram pincers.
This utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of open operation is pulled the gram pincers, comprise fixed handle and flexible handle, be connected by set bolt between fixed handle and the flexible handle, it is characterized in that: it also comprises tooth plate, claw beam, pull bar, clamp seat, runner and clamp, described fixed handle is provided with latch, and flexible handle is provided with stage clip; One end of tooth plate is fixed on the flexible handle, and stage clip is pressed into tooth plate; The tooth plate other end passes fixed handle, and latch snaps in tooth plate and matches each other; One end of claw beam is inserted in runner, and the other end and clamp seat are fixed, and runner is connected with fixed handle; Pull bar passes claw beam, and an end of pull bar is installed on the flexible handle, and the other end is connected with clamp; Described clamp has two, and two clamps are installed on the clamp seat, and the front end of two clamps is provided with noinvasive flute profile and release groove, and matches each other.
Flexible handle described in the utility model is provided with pull rod slot, and pull bar is provided with draw-bar seat, and draw-bar seat snaps in the pull rod slot.
The end of two clamps described in the utility model is provided with connecting plate, and clamp is connected with pull bar by connecting plate.
This utility model compared with prior art has following positive effect: reasonable in design, can effectively intestinal tissue be drawn and dissociate, and can the damaged tissue organ, operation is carried out smoothly.
