Abstract
The utility model designs bone prosthesis, especially middle tibia prosthese.A kind of middle tibia prosthese, is divided into main paragraph and canned paragraph, and described main paragraph human body front end face indent, described canned paragraph is divided into canned paragraph and lower canned paragraph, is connected by main paragraph.Specifically designed for the bone defects problem of middle tibia, good fixing effect, weight capacity is strong, it is not easy to infect, and the middle tibia prosthese for having certain resistance is clashed into for positive.
Description
Technical field
The utility model designs bone prosthesis, especially middle tibia prosthese.
Background technology
Wound or infection can all cause bone defects, and conventional at present is bone displacement technique, including itself bony site implantation
And Using prosthesis.There is the prosthese of different shape for different skeletal sites, be typically implanted into by the way of interior fixation.If
There is big section of defect of shin bone in patient, then more after it is often bad.Because femoral surface cortex is relatively thin, blood supply is not enough, if adopted
With conventional prosthese, repeated infection is easily caused, influence post-operative recovery, and shin bone bone is thinner, using easily occurring after prosthese
Fixed site comes off, and causes prosthese to be subjected to displacement, operative failure.Even if recovering good, run into follow-up life process big
Shock is likely to result in prosthese exposure, and life hidden danger is brought to patient.Defect is larger, and tibial prosthesis implantation risk is bigger,
Operating difficulty is also higher, so clinically many patients abandon using tibial prosthesis, causes lifelong disability.Currently without a kind of special
Prosthese of the door for middle tibia.
Utility model content
Problem to be solved：For problem above, the utility model provides a kind of middle tibia prosthese, specifically designed for shin
The bone defects problem in bone stage casing, good fixing effect, weight capacity is strong, it is not easy to infect, and has certain for positive shock
The middle tibia prosthese of resistance.
Technical scheme
A kind of middle tibia prosthese, is divided into main paragraph and canned paragraph, and described main paragraph human body front end face indent is described
Canned paragraph is divided into canned paragraph and lower canned paragraph, is connected by main paragraph.
Further, described main paragraph is spirality.
Further, described canned paragraph by taper interior filling fixing end and extension fixed plate.
Further, described extension fixed plate is provided with holding claw.
Further, described holding claw is arc.
Further, described holding claw is clamped by primary and secondary and fixed.
Further, described main paragraph and canned paragraph are provided with antimicrobial coating.
Further, a kind of described middle tibia prosthese is titanium alloy, is integrally formed.
Beneficial effect
The utility model provide technical scheme using indent design prosthetic main section, can be prevented effectively from because cortex compared with
The operation risk that strip comes, the patient to undergoing surgery does not require body weight and fat deposit thickness.Because indent is designed causes distance
Epidermis space is bigger, prevents cortex from cleaving, and blood supply abundance prosthese biocompatibility is more accelerated, and anti-infection ability is strong, and patient is postoperative
Recover fast.More after, if running into prosthese position frontal impact, because indent design dispersion stress, the work of protection is played to prosthese
With also because its surface cortex is thicker, it is not easy to cause prosthese position cortex to expose, protect prosthese.
1 main paragraph is spirality, and with stability higher, weight capacity is good, big with contact biological tissue area, there is provided
Several first more attachment surfaces, accelerate postoperation recovery speed.
Canned paragraph described in 2 uses subcutaneous bone outside solid first by the interior filling fixing end and extension fixed plate of taper
Determine part and fix the method combined with bones filling fixing phase, because shin bone is thinner, simple internal fixation stabilization is poor, and
Secondary injury easily is caused to shin bone, is unfavorable for the fixation of large defect prosthese, internal fixation can be viscous using bone cement etc.
Mixture.Outside is provided with extension fixed plate, and its moulding meets shin bone trial radian, is fixed on defect epimere, or defect lower end
Healthy bone part, is prevented from prosthese and is subjected to displacement or loosens.In view of operation technique difficulty, defect can be had more
The length of the distance between tibiofibula adjustment extension fixed plate.It is fixed to play and concentrates on middle tibia, shin bone fibula position
Relatively large place.
Extension fixed plate described in 3 is provided with holding claw, and described holding claw is arc, increases contact area, and shin bone is played
The effect of grasping, stability of the enhancing prosthese in human body.
Holding claw described in 4 is clamped by primary and secondary fixes, and primary and secondary pincers are relatively common bone surgery instruments, after fixing, by body
Outer redundance is removed, and safe ready, infection rate is low.
Main paragraph and canned paragraph described in 5 are provided with antimicrobial coating, can effectively prevent prosthetic surface particle-bound bacteria, and prevent hand
Postoperative acute infection, improves success rate of operation.
6 titanium alloys have good biocompatibility, and hardness is bigger, can play a part of load-bearing.It is integrally formed
Preparation technology does not have joint, and convenient sterilizing, intensity is higher, is conducive to load-bearing, while being not susceptible to damage.
