Description

A kind of safe microsurgery point-like distraction forcep

Technical field

This utility model is related to technical field of medical instruments, and specially a kind of safe microsurgery point-like struts Pincers.

Background technology

During microsurgery, for exposing wound surface, obtain roomy surgical field of view, usually edge of wound skin is often rectified with far and near Skin closure tractive is fixed, and exposes wound surface, and when the lower suture of naked eyes is fixing, suture dissection is damaged to the subcutaneous superficial vein of edge of wound Heavier, reduce and be available for vein anastomosis, lead to postoperative backflow obstacle, or even operative failure, sometimes expose and not need to suture again Tractive, wastes operating time, and exposure is excessively easily caused vascular suture overtension or cannot directly suture, and needs dermal sutures out Again suture is fixed afterwards, increases the risk for the treatment of, for this it is proposed that a kind of safe microsurgery point-like distraction forcep.

Utility model content

The purpose of this utility model is to provide a kind of safe microsurgery point-like distraction forcep, to solve the above-mentioned back of the body The problem proposing in scape technology.

For achieving the above object, this utility model provides a kind of following technical scheme: safe microsurgery point-like Distraction forcep, including upper handle and lower handle, be from left to right connected with turn between described upper handle and lower handle buffer unit and Adjusting rod, described lower handle has adjustment hole, and the upper end of described adjusting rod is fixed on handle, described adjusting rod another Adjustment hole is run through at end, and the surface of described adjusting rod has screw thread, and described adjusting rod is provided with two screws, and two described spiral shells Silk is respectively distributed to the both sides of adjustment hole, and described upper handle and lower handle pass through connecting pin interconnection, described upper handle and under The left end of handle is separately installed with lower clamp nozzle and upper clamp nozzle, and the left end of described upper clamp nozzle and lower clamp nozzle is mounted on strutting set, institute State buffer unit and include sleeve, the left and right inwall of described sleeve all offers chute, and the inner chamber of described sleeve is provided with spring, institute The inner chamber stating sleeve is socketed with t type bar, and described t type bar is arranged on spring top, and the cross bar left and right sides of described t type bar is all pacified Equipped with the draw runner matching with chute.

Preferably, the inner chamber of described adjustment hole is provided with valve rubber.

Preferably, described upper clamp nozzle is provided with miniature lighting lamp.

Compared with prior art, the beneficial effects of the utility model are: this utility model purpose is to overcome existing skill The deficiency of art and a kind of microsurgery point-like distraction forcep is provided, exposure wound surface opened by jaw, and to group when jaw opens Knit lesion size convenient control, easy to adjust, safe and reliable, thus saving operating time, the risk of the operation of reduction.
