Abstract
The invention belongs to medicine equipment instrument, a kind of specifically operating room medical personnel a kind of used positioning and guiding reaming screw tap, positioning and guiding reaming screw tap when being performed an operation to patient is constituted by changing hands handle and cored screw, it is characterized in that：It is fixed with the top of cored screw and changes hands handle, core bar is installed in the inside of cored screw, it is machined with the bottom of core bar top, cutting edge and screw thread are machined with the bottom of cored screw, the present invention is provided with core bar due to the inside in cored screw, it is machined with the bottom of core bar top, so when in use, first the position of top alignment patient spine, then it is rotated further by changing hands handle, cored screw is allowed to enter in the backbone of patient, in summary, the present invention not only significantly reduces the pain of patient, and greatly improve the operating efficiency of medical worker, avoid occurring malpractice.
Description
Technical field
The invention belongs to medicine equipment instrument, specifically operating room medical personnel to patient when performing an operation used one
Plant positioning and guiding reaming screw tap.
Background technology
Present hospital operating room medical personnel used reaming screw tap, simple in construction, function when being performed an operation to patient
It is single, do not reach the requirement of operation, this brings inconvenience to medical personnel, also brings pain to patient.
The content of the invention
The purpose of the present invention, in that overcome above-mentioned shortcoming, and a kind of reliable and stable positioning easy to use provided
It is oriented to reaming screw tap.
What the present invention was realized in：A kind of positioning and guiding reaming screw tap, is constituted by changing hands handle and cored screw, its
It is characterized in：It is fixed with the top of cored screw and changes hands handle, core bar is installed in the inside of cored screw, is added in the bottom of core bar
Work has top, and cutting edge and screw thread are machined with the bottom of cored screw.
It is above-mentioned to change hands handle and cored screw is integrated by being welded and fixed.
The present invention is provided with core bar due to the inside in cored screw, is machined with the bottom of core bar top, so makes
Used time, first the position of top alignment patient spine, then it is rotated further by changing hands handle, is allowed to the backbone that cored screw enters patient
It is interior.
Brief description of the drawings
The present invention will be further described in detail below in conjunction with the accompanying drawings.
Fig. 1 is front view of the present invention.
Fig. 2 is Fig. 1 " A-A " sectional view.
Each label declaration is as follows in figure：
1st, handle is changed hands, 2, cored screw, 3, core bar, 4, cutting edge, 5, screw thread, 6, sawtooth, 7, top.
Embodiment
The present invention is in order that with safety and sanitation, reliable and stable, whole parts are made using titanic alloy machining, wherein changing hands
Handle 1 and cored screw 2 are welded to together, and the effect for changing hands handle 1 is allowed to cored screw 2 by changing hands handle 1
The cutting edge 4 and screw thread 5 of bottom enter in the backbone of patient, and medical personnel need to be downwardly applied to pressure while handle 1 is changed hands in rotation
Power, such cored screw 2 is easier into the backbone of patient, and top 7, the effect of core bar 3 are machined with the bottom of core bar 3
Exactly it is oriented to, top 7 effect is exactly to position, the effect of cutting edge 4 is exactly to play a part of self tapping, the effect of screw thread 5 is exactly empty
After heart screw rod 2 enters in the backbone of patient, stable and fixed effect is played, the effect of sawtooth 6 is exactly the top layer of cuts bone.
In summary, the present invention not only significantly reduces the pain of patient, and greatly improves the work effect of medical worker
Rate, it is to avoid occur malpractice.
Claims (1)
1. a kind of positioning and guiding reaming screw tap, is constituted by changing hands handle and cored screw, it is characterized in that：In the upper of cored screw
Portion, which is fixed with, changes hands handle, and core bar is provided with the inside of cored screw, be machined with the bottom of core bar it is top, in cored screw
