Description
Technical Field
The utility model relates to the technical field of medical equipment, in particular to a saddle bottom dura mater scissors for operation.
Background
When the pituitary tumor operation is performed, the dura mater under the saddle needs to be opened. The method comprises cutting the dura mater transversely with a hook knife to form a straight opening, and cutting the dura mater with scissors from both sides to the top. When the dura mater is cut to scissors that use at present, the accurate position is difficult to judge to one of cutting edge outside the dura mater, another under the dura mater (can not see). When the dura mater outside the saddle is cut, the incision is close to the internal carotid artery, and the cut dura mater may cause damage to the internal carotid artery. Once injury to the internal carotid artery occurs, uncontrolled massive hemorrhage may result, even life threatening to the patient, with serious consequences. Therefore, there is a need for an improved scissors.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above problem, provide a saddle bottom dura mater scissors for operation of simple structure, convenient to use, multiplicable operation security.
The technical scheme is as follows:
a pair of saddle-bottom dura mater scissors for operation comprises a fixed handle, a shearing handle, a sleeve, a connecting rod, a scissor seat and a movable scissor head, and is characterized in that the fixed handle is connected with the upper part of the shearing handle through a pin shaft, the upper end of the fixed handle is provided with the sleeve supporting seat, the sleeve supporting seat and the fixed handle are of an integral structure, a sleeve insertion hole is arranged on the front end surface of the sleeve supporting seat, the rear end of the sleeve is fixedly arranged in the sleeve insertion hole, the sleeve is internally provided with the connecting rod insertion hole in a penetrating way with the sleeve supporting seat, the scissor seat is fixedly arranged at the front end of the sleeve according to a set angle, the upper end of the scissor seat is provided with an isolation pushing head in an arc convex way, the two side walls of the scissor seat are respectively thickened, movable scissor grooves are arranged on the oblique wall and the root part of the scissor seat, the inner wall of each movable scissor groove is a scissor blade, the lower part of each movable scissor groove is communicated with the connecting rod insertion hole, the movable scissor head is fixedly arranged in each movable scissor groove through the pin shaft, the cutting edge of the movable scissor head and the cutting edge of the movable scissor groove form a cutting edge correspondingly, the connecting rod is arranged in the connecting rod jack, the front end of the connecting rod is fixedly connected with the lower end of the movable scissor head through the movable shaft, and the rear end of the connecting rod is fixedly arranged on the cutting handle.
The utility model discloses a use method: when in operation, the dura mater is transversely cut into a straight opening by using a hook knife, and then the dura mater is cut upwards from two sides by using scissors. When the dura mater on the outer side of the saddle bottom is cut, the isolation pushing head and the two side walls of the shear seat automatically push the nearby internal carotid artery outwards to leave the cutting range, so that the aims of protecting the internal carotid artery and safely cutting the carotid artery are fulfilled.
The utility model discloses when cutting the dura mater, the most advanced peripheral promotion head of cutting edge under the dura mater and scissors seat both sides wall part can push away the internal carotid artery to the outside, make the internal carotid artery leave the scope of cutting. Even if the knife edge under the dura mater can not be seen, the dura mater under the saddle can be cut off smoothly, meanwhile, the internal carotid artery is protected stably, and the safety of the operation is greatly improved.
