Abstract
The utility model relates to a medical instrument, in particular to a toothed nucleus pulposus clamp which comprises fixed clamp handles, an upper clamp slice, a lower clamp slice, a spreading spring and a pin shaft, wherein the clamp handles include a front clamp handle and a rear clamp handle; hinge holes are correspondingly formed at the front end parts of the front clamp handle and the rear clamp handle and are hinged with each other through the pin shaft. The nucleus pulposus clamp is characterized in that zigzag structures occluding with each other are arranged on the occlusal surface of the upper clamp slice and the lower clamp slice; the occlusal surface of the upper clamp slice and the lower clamp slice is in the shape of a rack, which is convenient for processing, cleaning and the increase of the occlusive force between the upper clamp slice and the lower clamp slice; during the operation process, the zigzag structures occluding with each other are arranged on the occlusal surface of the upper clamp slice and the lower clamp slice, so that the friction coefficients between the upper and the lower clamp slices and the human tissue are increased; in the operation, the upper clamp slice and the lower clamp slice firmly grip the human tissue; and during the traction process, the phenomenon that the human tissue is slipped off the space between the upper clamp slice and the lower clamp slice cannot occur. The utility model has the advantages of simple structure, convenient use, shortness of operation time, reduction of operation risk, relief of patient pain, good treatment effect, etc.
Description
Technical field:
This utility model relates to a kind of medical apparatus and instruments, and particularly a kind of profile of tooth vertebral pulp easy to operate, that result of use is good clamps.
Background technology:
As everyone knows, the vertebral pulp pincers are by the pincers handle, under clamp sheet, upper pliers plate, opening spring and bearing pin forms, pincers handle and forceps major handle before the pincers handle divides, the leading section correspondence of preceding pincers handle and forceps major handle is provided with hinge hole and is hinged by bearing pin, during use, make upper pliers plate and following pincers sheet realize opening or closing the state of closing by the handling tongs handle, so that upper pliers plate is bitten tissue and is carried out tractive with following pincers sheet, the occlusal surface of the upper pliers plate of existing vertebral pulp pincers and following pincers sheet is the plane, when in operation, usually occurring being pulled, the tissue of biting is from upper pliers plate and slippage between the pincers sheet down, cause the tractive failure and carry out tractive again, repeatedly tractive not only prolongs operating time, increase patient's pain, also increased operation risk.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of profile of tooth vertebral pulp easy to operate, safe in utilization pincers are provided.
This utility model can reach by following measure:
A kind of profile of tooth vertebral pulp pincers, comprise solid pincers handle, upper pliers plate, down clamp sheet, open spring and bearing pin, pincers handle and forceps major handle before the pincers handle divides, the leading section correspondence of preceding pincers handle and forceps major handle is provided with hinge hole and is hinged by bearing pin, it is characterized in that the occlusal surface of upper pliers plate and following pincers sheet is provided with the broached-tooth design of mutual interlock, to increase the gmatjpdumamics between upper pliers plate and following pincers sheet.
The occlusal surface of upper pliers plate in this utility model and following pincers sheet is spline-simulating, processes, cleans with convenient.
During this utility model surgical operation, be provided with the broached-tooth design of mutual interlock by the occlusal surface of upper pliers plate and following pincers sheet, increased the coefficient of friction between upper pliers plate and following pincers sheet and tissue, thereby increased upper pliers plate and clamped the grasping force of sheet down tissue, the tissue that upper pliers plate and following pincers sheet are firmly bitten in operation, be pulled through in sustenance and can not occur tissue in the journey from upper pliers plate and following slip phenomenon between the pincers sheet, have simple in structure, easy to operate, shorten operating time, reduce operation risk, reduce patient's pain, advantage such as therapeutic effect is good.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing this utility model is further described:
As shown in drawings, a kind of profile of tooth vertebral pulp pincers, comprise solid pincers handle, upper pliers plate 3, under clamp sheet 4, open spring 5 and bearing pin, pincers handle 1 and forceps major handle 2 before the pincers handle divides, the leading section correspondence of preceding pincers handle 1 and forceps major handle 2 is provided with hinge hole and is hinged by bearing pin, the structure of above-mentioned each ingredient is same as the prior art, this does not give unnecessary details, the occlusal surface of upper pliers plate 3 and following pincers sheet 4 that is characterised in that of the present utility model is provided with the broached-tooth design of mutual interlock, to increase the gmatjpdumamics of 4 of upper pliers plate 3 and following pincers sheets, the occlusal broached-tooth design of upper pliers plate 3 and following pincers sheet 4, can adopt straight-tooth, also can adopt the curve tooth, during surgical operation, be provided with the broached-tooth design of mutual interlock by the occlusal surface of upper pliers plate and following pincers sheet, thereby increased the coefficient of friction between upper pliers plate and following pincers sheet and tissue, the tissue that upper pliers plate and following pincers sheet are firmly bitten in operation, tissue in traction process, can not occur from slip phenomenon between upper pliers plate and following pincers sheet, the utlity model has simple in structure, easy to operate, shorten operating time, reduce operation risk, reduce patient's pain, advantages such as therapeutic effect is good.
