Description
Technical field
The utility model relates to medical operating assistive device fields more particularly to a kind of orthopaedics art to be positioned with stereopsis
Instrument.
Background technique
In hospital's spinal surgery clinical operation, intervertebral spinal fusion endoscope minimally invasive operation has been widely used in clinical treatment vertebra
Disc herniation.Minimally invasiveization of intervertebral foramen endoscopic surgery requires accurate positioning and operation in its art, and intervertebral foramen scope is logical at present
The foundation in road needs repeated multiple times under fluoroscopy perspective and position adjustment that can just obtain preferable position, when needing to spend many
Between have an X-rayed and adjust, perspective repeatedly increases the radiation hazradial bundle of operation related personnel and patient, and repeatedly adjustment also increases patient
Pain, extend unnecessary operating time, and multiple perspective and adjustment is also difficult that optimum position can be obtained, and will affect
The therapeutic effect of operation.Operation optimum position can be obtained in order to reduce perspective number, also once had developed a kind of 3 D stereo
Image position indicator is thrown by having an X-rayed in the body surface positive side position of surgical site according to point and body surface target using coplanar and collinear theory
Enter pin mark and place position indicator, the position into needle can be accurately positioned and enter needle angle, reducing perspective number can be obtained in intervertebral foramen
The ideal position in mirror channel shortens operating time to improve operation precision.But the 3 D stereoscopic image position indicator is using
Two position indicators of middle needs are used cooperatively in pairs, operate relatively cumbersome complexity.Therefore, research and develop a kind of structure it is simple, it is easy to operate,
Registration can be realized in exclusive use, improves operation precision, shortens operating time, and the orthopaedics art for reducing radiation hazradial bundle is three-dimensional
Image position indicator is the task that this field needs to complete.
Summary of the invention
The purpose of the utility model is to provide a kind of structures, and registration can be realized in simple, easy to operate, exclusive use,
Improve operation precision, the orthopaedics art stereopsis position indicator for shortening operating time, reducing radiation hazradial bundle.
In order to achieve the above object, the utility model uses following structural principle: a kind of orthopaedics art is positioned with stereopsis
Instrument, by fixed arm, adjusting nut, travelling arm, sliding needle, support arm, A-frame, the second support arm, the second sliding needle, second
Travelling arm, the second fixed arm, adjusting nut, tip positioning column and vertical shaft composition, its main feature is that: one side leg of right angle trigonometry bracket
The parallel fixed strip shape support arm in top, support arm cantilever end are vertically and fixedly provided with vertical shaft upwards；Cylindricality fixed arm lower end surface is equipped with
Indent axis hole, is rotatably assorted and covers on vertical shaft, and one side surface of fixed arm is equipped with vertical internal concave hopper chute；Cross is equipped in internal concave hopper chute
To exerted bolt, the through-hole that the first adjusting nut passes through in the middle part of cylindricality travelling arm on connector is tightened on exerted bolt,
The dynamic cooperation insertion cylindrical slid needle in the hollow one end of travelling arm；Another side leg top of right angle trigonometry bracket then fixed strip
The second support arm of shape, the second fixed arm, the second travelling arm, the second sliding needle and the second adjusting nut and support arm fixed thereon
The fixed arm of upper fixation, travelling arm, the structure and connection relationship of sliding needle and the first adjusting nut are identical；Right angle trigonometry bracket two
The lateral fixed tip positioning column bottom end of supporting leg infall, tip end is hanging, and tip and fixed arm and the second fixed arm are overlapped
Axial space intersection, to constitute a kind of orthopaedics art stereopsis position indicator.
The fixed arm vertical phase in the inner plane space of A-frame with the vertical internal concave hopper chute on the second fixed arm
It is right.
The utility model is during surgery in use, correspond respectively to C-arm or G arm for two rotatable fixed arms
Two vertical perspective planes in, the direction for adjusting two fixed arms by adjusting nut is vertically opposite, then slides and rotate two
The height and angle of a travelling arm make it be respectively directed to target spot in two vertical perspective planes respectively, and making can be from sliding
The sliding needle needle point intersection that arm skids off.It at this moment is to be directed toward body from sliding needle needle point intersection point to tip positioning column tip direction line
The direction of interior target spot.The utility model utilizes coplanar and collinear theory, is shone by having an X-rayed to throw in the body surface positive side position of surgical site
Point and body surface target enter pin mark and place position indicator, can be accurately positioned and enter needle angle into the position of needle and three-dimensional, to only pass through
Simple pivot operation is the ideal position that can reach foramen intervertebrale lens channel.
The utility model structure is simple, registration can be realized in easy to operate, exclusive use, improves operation precision, contracting
Short operating time reduces the radiation hazradial bundle of medical staff and patient, has reached goal of the invention.
