Abstract
The invention relates to a combined tibiofibular embracing fixator which comprises a fibula embracing body, fibula embracing arms and tibia embracing drawing hooks, wherein the fibula embracing arms and the tibia embracing drawing hooks are integrated into a whole; the fibula embracing body is provided with the fibula embracing arms and the tibia embracing drawing hooks; the tibia embracing drawing hooks are positioned among the fibula embracing arms; and both sides of each group of fibula embracing arms and both sides of each tibia embracing drawing hook are provided with antiskid ratchets. The combined tibiofibular embracing fixator has the advantages of simple technological shape and reasonable structure, and is favorable for reducing the operation of manually damaging bones in an operation; and the combined tibiofibular embracing fixator is convenient in utilization in the operation and is firmly and reliably fixed. After the combined tibiofibular embracing fixator is installed, not only fibula fracture can be treated, but also distal tibiofibular separation puzzled by clinical doctors can be treated. The combined tibiofibular embracing fixator of the invention has excellent application value and application prospect; a satisfactory curative effect can be obtained by reasonable application; and compared with operations for treating ankle fracture combined with distal tibiofibular joint separation and the like by using absorbable screws, the combined tibiofibular embracing fixator is more favorable for improving the living quality of patients to a certain degree and has excellent economic and social benefits.
Description
Technical field
The present invention relates to medical apparatus and instruments, particularly surgery, orthopaedics are for implanting a kind of medical material Combined tibiofibular embracing fixator of implants being beneficial to the optimum healing of fracture in diaphysis.
background technology
Sprained ankle often with Distal tibiofibular diastasis, in conventional processing method: application lag screw or thick cancellous bone screw replacement and fixation.This process often develops complications, such as: fix three layers of cortex and fix loosely, fix four layers of cortex later stage screw extraction etc., screw entry point is bad or cannot grasp because of classification of fracture.Application Usingclavicular Hook Plate separation of Jower tibiofibular joint, Semi-circular groove outer tube of tibiofibula or fractures in children with absorbable screws ankle fracture and separation of Jower tibiofibular joint time, postoperative screw often needs to take out at 3-4 month, increases the painful and financial burden of operation.Screws etc. are non-resilient fixing, easily cause screw extraction etc.
summary of the invention
The present invention will solve the screw replacement and fixation that exists in prior art loosely, postoperative screw often needs to take out, increase the problems such as operation misery and financial burden and screw easily rupture, a kind of elastic modelling quantity is provided to be only 1/4th of other rustless steel implants, close with the elastic modelling quantity of skeleton, after implanting, stress shielding is little, is beneficial to the Combined tibiofibular embracing fixator of the optimum healing of fracture.
Technical problem of the present invention adopts following technical proposals to solve:
A kind of tibia fibula commissural arch clasping spine, this Combined tibiofibular embracing fixator adopts to be had temperature memory function, has the material of good biocompatibility simultaneously and make, encircle body by fibula, encircle the fibula of body one with fibula and encircle arm and encircle drag hook form with the tibia that fibula encircles body one, described fibula is encircled body and is provided with described fibula and encircles arm and tibia encircles drag hook, described fibula encircle arm be provided with at least 2 right, described tibia encircle drag hook 2 pairs of fibulas encircle between arm along on the position of fibula length bearing of trend.
Described fibula encircle arm be provided with 2 ~ 8 right.
Described often pair of fibula is encircled the both sides that the both sides of arm and each tibia encircle drag hook and is provided with anti-skidding ratchet.
Described fibula is encircled body and is rolled into by sheet material.
The present invention selects in prior art the material having temperature memory function, have good biocompatibility simultaneously, as Ti-Ni marmem, make full use of shape distortion---the recoverable feature of memorial alloy, art shapes is simple, rational in infrastructure, be conducive to the operation reducing artificial destruction skeleton in operation, the fibula adopting the fibula that rolled into by sheet material to encircle body and one is encircled arm and tibia and is encircled the structure that drag hook forms, persistent pressure function after shape recovery, be conducive to Combined tibiofibular embracing fixator and fibula close contact and with the drawing close of tibia, prevention fibula lower end is separated with tibia lower end, tibia is encircled drag hook and is not only had memory performance, under hot, also there is super elastic characteristics, and form elasticity and draw over to one's side, prevent because external force is excessive or too quickly and cause drag hook to rupture, significant therapeutic effect is had for merging the lower tibiofibula osteodiastasis caused because of ankle joint fracture.Structure of the present invention is simple, easy to use in operation, fixation, reliable.After Combined tibiofibular embracing fixator is installed, can not only fracture of fibula be treated, and the Distal tibiofibular diastasis of clinician's headache can be treated.The present invention has good using value and application prospect, reasonable application can obtain satisfactory effect, with fractures in children with absorbable screws ankle fracture and separation of Jower tibiofibular joint etc. perform the operation compared with more contribute to improving quality of life of patient to a certain extent, there is good economic and social benefit.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail:
A kind of tibia fibula commissural arch clasping spine, is encircled body 2 by fibula and is encircled arm 1 with the fibula that fibula encircles body 2 one and encircle drag hook 3 with the tibia that fibula encircles body 2 one and form.Fibula is encircled body 2 and is rolled by sheet material and form.Fibula is encircled and body 2 is provided with fibula and encircles arm 1 and tibia encircles drag hook 3, fibula encircle arm 1 can be provided with 2 ~ 8 to or more, tibia is encircled drag hook 3 and is encircled between arm 1 at two pairs of fibulas.Tibia encircles drag hook 3 can 1 ~ 4 or more.Fibula encircles the both sides that the both sides of arm 1 and each tibia encircle drag hook 3 can arrange anti-skidding ratchet 4.
Combined tibiofibular embracing fixator, comprise fibula and encircle body 2 and fibula encircles arm 1 and tibia encircles drag hook 3, fibula is encircled the fibula that body 2 is provided with arc and is encircled arm 1, fibula is encircled fibula on body 2 and is encircled and be provided with tibia between arm 1 and encircle drag hook 3, and fibula encircles the both sides that the both sides of arm 1 and each tibia encircle drag hook 3 can arrange anti-skidding ratchet 4.This Combined tibiofibular embracing fixator adopts to be had temperature memory function, has the material of good biocompatibility simultaneously and make, and can be out of shape and be placed on tibia and fibula, after implanting, complex realizes fixing.
Fibula is encircled arm 1 in brine ice by distraction forcep during installation to launch, the amplitude of opening making every a pair fibula encircle arm 1 is greater than fibula diameter, be placed on fibula, tibia is encircled drag hook 3 launches close to straight simultaneously, tibia is encircled drag hook 3 and crosses on front side of tibia, be buckled on tibia, then encircle arm 1 and tibia with hot salt brine hot compress fibula to encircle drag hook 3 and make continuous pressurization after its recovery of shape, fibula is encircled arm 1 and is held fibula tightly, forms reliable internal fixtion, is conducive to diseased symphysis; Tibia is encircled drag hook 3 and is strained, and makes fibula and tibia tightly draw close, is no longer separated, and promotes the growth of the ligament between lower tibiofibula, reaches the effect for the treatment of fracture of fibula and lower tibiofibula osteodiastasis.
