Description
Technical field
The utility model relates to the field of medical instrument technology, and in particular to a kind of ankle fusion plate.
Background technique
Currently, clinically for the ankle-joint joint osteoarthritis patient in advanced stage, can using prosthetic replacement and
Facet fusion surgery.Since the service life of artificial joint replacement is short, only several years time, and also it is costly, so facing
Using most or ankle-joint fusions on bed.Ankle fusion needs to be implanted into internal fixation screw plate, but current energy
The shortcomings that inside-fixture enough used is all common some nail-plates for long bone fracture, these nail-plates is to need bending in art
Moulding, reduces the intensity of inside-fixture, then has that be exactly tibial astragaloid joint two sides unreasonable due to nail hole position, can be placed in
Screw is very few, and fixation is shaky, is easy broken nail and breaks plate, leads to Unstable internal fixation, therefore there is an urgent need to a kind of in herein
Material is fixed to solve the problems, such as this.
Clinically have at present using the dedicated philos plate of proximal humeral fracture for ankle fusion, why uses
The fixture primarily to overcome it is common rebuild class inside-fixture astragalus dispose into screw very few (be generally only capable of merging two
Piece), the drawbacks such as screw monoplane merging improve the success rate of fusion to increase the stability of fusion.But philos plate
The shortcomings that be also apparent: intensity is not enough to support the weight of human body, still have broken nail break plate possibility, the direction of screw and
Position does not meet the anatomical features of astragalus, it is still desirable to which bending in art further reduced the intensity of inside-fixture.Therefore, compel
It is essential and wants a kind of inside-fixture for being exclusively used in ankle fusion.
Utility model content
To solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of ankle fusion plate.
The technical solution of the utility model is as follows:
A kind of ankle fusion plate, it is characterised in that: connect including the shin bone fixed part being in contact with shin bone and with astragalus
The astragalus fixed part of touching, the shin bone fixed part are an integral structure with astragalus fixed part, which locks equipped with shin bone
Determine hole, which is equipped with astragalus lock hole；Sliding pressurization hole is additionally provided on the shin bone fixed part, for installing skin
Matter bone screws at tibial astragaloid joint fusion to pressurizeing.
Wherein, which is titanium alloy material preparation.
Wherein, the angle of the astragalus fixed part and shin bone fixed part is 173 °.
Wherein, the length of the ankle fusion plate is 95.9mm, width 12-20mm, with a thickness of 2mm.
Wherein, the axis of the shin bone lock hole, sliding pressurization hole and astragalus lock hole is each perpendicular to the shin bone and fixes
Portion.
Wherein, sliding pressurization hole is slotted hole.
Wherein, the shin bone lock hole and astragalus lock hole are 6 millimeters of nominal diameter of threaded hole.
Wherein, the shin bone fixed part matches with the shape of shin bone, the shape kissing of the astragalus fixed part and astragalus
It closes.
Wherein, including three astragalus lock holes and three shin bone lock holes.
Wherein, three shin bone lock holes and sliding pressurization Kong Chengyi straight line are arranged in the shin bone fixed part, wherein
The axis of one astragalus lock hole is vertically intersected on the straight line.
The utility model has an advantage that
The ankle fusion plate of the utility model has the characteristics that meet skeleton dissection, intensity height, the spy of good fixing effect
Point, and with sliding pressurization function, can be improved fusion rate, prevent broken nail break plate phenomena such as generation.This product design meets
Difficulty is not present in the requirement of biomethanics, the processing of material, and matches with existing lower limb internal fixation screw general, improves
The convenience of clinical application reduces production cost.

Specific embodiment
Now in conjunction with examples and drawings to the construction of the utility model, shape and the further details of explanation of feature.It should
Understand, the present embodiment is merely to illustrate the utility model, rather than limits the protection scope of the utility model.
Ankle fusion plate 0, is made of titanium alloy material comprising integrated astragalus fixed part 1 and shin bone fixed part 2,
1 shape of astragalus fixed part matches with shin bone, and 2 shape of shin bone fixed part matches with shin bone, and astragalus fixed part 1 is bonded to non-bone
Face deviates 7 °, therefore the angle a of astragalus fixed part 1 and shin bone fixed part 2 is 173 °；The entire length of ankle fusion plate 0 is
95.9mm, width 12-20mm, with a thickness of 2mm.Astragalus fixed part 1 be equipped with astragalus lock hole 11, astragalus lock hole 12 and away from
Bone lock hole 13；On shin bone fixed part 2 from tibial side proximal end to be distally successively arranged shin bone lock hole 21, sliding pressurization hole 24,
Shin bone lock hole 22 and shin bone lock hole 23；Astragalus lock hole 11 is located at astragalus side distal end, astragalus lock hole 12 and astragalus locking
Hole 13 it is parallel be set to astragalus side proximal end；Three shin bone lock holes and three astragalus lock holes are 6 millimeters of nominal diameter of spiral shell
Pit.
It is additionally provided with the sliding pressurization hole 7 of an oblong on the shin bone fixed part 2, can be used os integumentale screw to tibial astragaloid joint
It pressurizes at fusion, to improve fusion rate.Three shin bone lock holes and sliding pressurization hole 24 are arranged in shin bone in a straight line and consolidate
Determine portion 2, the axis of astragalus lock hole 11 is vertically intersected on the straight line.
Astragalus lock hole, the pitch-row of shin bone lock hole, aperture meet national standard YZB/ state 2382-2015.
