Abstract
The utility model relates to a with bone traction navigation head, including bracket and the sleeve that has the J -shaped cross -section, the arc recessed groove in J -shaped cross -section be used for the heel fixed, two terminal surfaces of bracket on all be fixed with a locating lever, the both ends of locating lever are fixed in arc recessed groove both sides, the locating lever on have a plurality of muffjoint holes, muffjoint hole one -to -one on two locating levers, sleeve and muffjoint hole threaded connection. The beneficial effects of the utility model are that compare with prior art, have a plurality of piercing part bit select points, be favorable to the puncture location, steel needle perpendicular to surface of bone all the time can be guaranteed to the puncture process, draws the line of force and can not produce the deviation, patient's foot is fixed firm, and can not rock at will influences pjncture needle angular discrepancy.
Description
Technical field
This utility model relates to a kind of operating theater instruments auxiliary device, is specifically related to a kind of calcaneal traction guider.
Background technology
Calcaneal tuberosity traction is a kind of very conventional Bone traction technology, is mainly used in fracture of the tibial plateau, unstable fracture, open tibial, comminuted fracture.By by lower edge line midpoint behind ankle tip and heel, from inside to outside through calcaneus, passing a draw point, apply trailing weight by draw point.
Current draw operations is mainly rule of thumb completed by patient, has following defect: (1) site of puncture is non-constant, easily injures nervus vasculairs, causes constant pain；(2) cannot ensureing in piercing process that draw point is perpendicular to surface of bone all the time, cause puncture needle and lower limb line of force out of plumb, the traction line of force has deviation, causes patient uncomfortable；(3) in piercing process, the foot of patient is not fixed, and rocks the pain that can increase the weight of pre existing fracture position, causes puncture needle angular deviation simultaneously.
Utility model content
The purpose of this utility model is in that to overcome the deficiencies in the prior art, it is provided that a kind of calcaneal traction navigation, it is possible to effectively fix foot, and guided puncture draw point is perpendicular to surface of bone and punctures.
To achieve the above object of the invention, a kind of calcaneal traction guider is provided, including bracket and the sleeve with J-shaped cross section, described J-shaped cross section has arc-shaped recess groove to fix for heel, being respectively and fixedly provided with a positioning rod on two end faces of described bracket, the two ends of described location bar are fixed on arc-shaped recess groove both sides, and described location bar has multiple sleeve connection hole, sleeve connection hole one_to_one corresponding on two location bars, described sleeve is threadeded with sleeve connection hole.
The vertical component of described J-shaped section brackets is for instep laminating, then embedding as restriction in arc-shaped recess groove with heel, ankle is stuck on bracket, forms one and fixes, ankle restraining belt on bracket then forms the second layer and fixes, and makes patients feet not easily shifted by dual fixing.Described location bar there is sleeve connection hole, is connected with bush whorl, by installing the draw point that sleeve steering to puncture, it is ensured that draw point is vertical with bone.
Preferably, the arc-shaped recess groove of described bracket is extended with the footrest structure of the curved surface for fixing ankle.
Preferably, also include ankle restraining belt to be fixed on bracket.
Preferably, described ankle restraining belt one end is fixed on an end face of bracket, and the other end of ankle restraining belt is connected on another end face of bracket by thread gluing.
Preferably, described ankle restraining belt one end is fixed on an end face of bracket, and the other end of ankle restraining belt is by snapping connection on another end face of bracket.
Suffering limb foot is placed in the arc-shaped recess groove of bracket by calcaneal traction device of the present utility model, and owing to bracket cross section is J-shaped, therefore instep is close to the vertical component of bracket；Ankle restraining belt is used for fixing foot；There are several sleeve connection holes on the securing lever, select suitable connecting hole, the sleeve being threaded one end is screwed into connecting hole；Electric drill is used draw point to penetrate calcaneus to offside.Calcaneal traction guider has multiple puncture selected element, facilitates doctor to position, and the shape of restraining belt and bracket itself is formed dual fixing, is conducive to stable patient；Additionally the threaded engagement of sleeve and connecting hole connects, and not only plays guiding function but also can guarantee that puncture is vertical with bone, is conducive to the subsequent operation of draught line.
The beneficial effects of the utility model are compared with prior art, have multiple sites of puncture selected element, are conducive to Needle localization；Piercing process can ensure that draw point is perpendicular to surface of bone all the time, and the traction line of force will not produce deviation；Patients feet is fixed, will not arbitrarily wobble effects puncture needle angular deviation.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described further.
A kind of calcaneal traction device according to Fig. 1, Fig. 2, including bracket 1, bracket 1 has bottom surface and lateral surface, bottom surface and lateral surface are mutually perpendicular to, and the medial surface of described bracket 1 is J-shaped, and therefore bracket 1 has the cross section of J-shaped, in addition, bracket 1 also has two end faces.The vertical component of described bracket 1 is to be close to for foot face, and heel is predominantly disposed in arc-shaped recess groove 11 place of J-shaped, and the arc-shaped recess groove 11 of bracket 1 is extended with the footrest structure 12 of the curved surface for fixing ankle.Being fixed with location bar 2 on described end face, the end points of location bar 2, one end is fixed on the side of arc-shaped recess groove 11, and the other end is then fixed on the opposite side of arc-shaped recess groove 11, inclined layout.Described location bar 2 has string sleeve connection hole 5, described sleeve connection hole 5 is threaded sleeve 3, each end face is fixed with a location bar 2, and sleeve connection hole 5 one_to_one corresponding on the bar 2 of location, described one_to_one corresponding refers to the axis coaxle between corresponding two sleeve connection holes.Having ankle restraining belt 4, ankle restraining belt 4 one end to be fixed on an end face of the intersection of bracket 1 on described bracket 1, the other end can be fixed on other end by fishing without hook or buckle.
Use procedure is as follows: be placed in arc-shaped recess groove by suffering limb foot, and bottom surface is close in foot face；Ankle restraining belt is fixed；Select suitable connecting hole, the sleeve being threaded one end is screwed into connecting hole；Electric drill is used draw point to penetrate calcaneus to offside
Below the preferred embodiment this utility model created has illustrated, but this utility model is created and is not limited to described embodiment, those of ordinary skill in the art can also make all equivalent modification or replacement under the premise without prejudice to this utility model creative spirit, and these equivalent modifications or replacement are all contained in the application claim limited range.
