Description
Technical field
This utility model relates to technical field of medical instruments, particularly a kind of spinal column artificial intervertebral disk implant surgery notcher.
Background technology
The upper and lower both sides of artificial intervertebral disk are standing protruding profile of tooth, has the function of anti-back and incipient stability.Notcher is outputed the required groove of profile of tooth at upper hypocentrum during in order to artificial intervertebral disk implant surgery.The more difficult precise positioning of notcher of the prior art, and easily squeezed into deeply or excessively shallow, affect operating time and efficiency.
Utility model content
The purpose of this utility model is to overcome the defect that prior art exists, and a kind of simple in structure, easy to operate spinal column artificial intervertebral disk implant surgery notcher is provided.
The technical scheme that realizes this utility model object is: a kind of spinal column artificial intervertebral disk implant surgery notcher, has notcher head, handle, extracts groove and knock afterbody; Described notcher head is arranged on handle front end, and the head of notcher head is provided with four cutting edges; Described handle rear end is provided with and knocks afterbody; Described knocking between afterbody and handle is provided with and extracts groove; The head of described notcher head is provided with limit guiding device; Described limit guiding device is arranged on cutting edge top, and the both sides of limit guiding device have symmetrically arranged " U " shape groove.
The skid resistant course that described in technique scheme, the surface of handle has annular knurl or forms by sandblast.
Adopt after technique scheme, the utlity model has following positive effect:
(1) notcher head monnolithic case of the present utility model mates with vertebral body anatomical shape; Intermediate handle portion surface is through anti-skidding processing such as annular knurl, sandblasts; When afterbody is extracted groove and is used as to extract in order to connect extractor; Knocking the available hammer in tail place knocks when being used as notcher and squeezing into.
(2) this utility model can by notcher via guide needle location with and when slotting, do spacing prevent from squeezing into dark.
