Abstract
The utility model discloses an extensor tendon stop fixer, include: dead lever and screw, the dead lever is a font, and the dead lever both ends are equipped with solid fixed ring, has the screw hole gu fixed ring goes up to open, and the screw hole is the eccentric orfice, the screw has two, and two screws set up respectively in solid fixed ring's screw hole. In this way, the utility model discloses can realize tendon stop threadiness rebuilds.
Description
Technical field
The utility model is related to extensor tendon stop and rebuilds internal fixation material field, and more particularly to a kind of extensor tendon stop is solid
Determine device.
Background technology
Hand injury extensor digitorum muscle of hand tendon stop avulsion, operation is given tendon stop to rebuild and is rebuild and stop frequently with wire binding, rivet
Point.Wire binding operation is simple, and medical expense is low, but postoperative needle track nursing trouble, easily cause infection, need second operation to take
Go out interior fixation, postoperative patient life inconvenience, patient does not allow to be easily accepted by.In recent years with the development of inside-fixture, give tendon with rivet
Stop reconstruction is also through frequently with postoperative patient is not required to needle track nursing, little on life impact, is not required to give interior fixation to take out, but postoperative
Find that some cases rivet has loosening, subcutaneous knot reaction is big.The reason summary causes problem above has: 1) rivet belongs to point-like and stops
Point is rebuild, and tendon stop is wire；2) rivet fixed-direction is similar to tendon line of force direction；3) stop knot is more, suture
Thicker；4) extensor tendon stop dorsal skin is relatively thin.
Utility model content
Mainly solving the technical problems that providing a kind of extensor tendon stop fixator, fixator can not prefetch the utility model
Go out, extensor tendon fixator meets tendon stop wire and rebuilds, reduce suture prevention knot reaction, screw fixed-direction and tendon power
Line is vertical, postoperative be difficult to loosen, screw position leans on both sides, it is to avoid top pressure extensor tendon stop dorsal skin.
For solving above-mentioned technical problem, the technical scheme that the utility model adopts is: provides a kind of extensor tendon stop
Fixator, comprising: fix bar and screw, described fix bar is in door font, and fix bar two ends are provided with retainer ring, retainer ring has
Screw hole, screw hole is eccentric orfice；Described screw has two, and two screws are separately positioned on the screw in the hole of retainer ring.
Preferably, described fix bar includes cross bar and is fixed on the montant at cross bar two ends, tilts to set between montant and cross bar
Put.
Preferably, described screw is cancellous bone screw.
The beneficial effects of the utility model are: the utility model extensor tendon fixator meets tendon stop wire and rebuilds, and subtracts
Few suture prevention knot reaction, screw fixed-direction is vertical with the tendon line of force, postoperative is difficult to loosen.
Brief description
Fig. 1 is the perspective view of the utility model extensor tendon stop fixator one preferred embodiment；
Fig. 2 is the use state structural representation of shown extensor tendon stop fixator.
In accompanying drawing, the mark of each part is as follows: 1, fix bar；2nd, retainer ring；3rd, screw.
Specific embodiment
Below in conjunction with the accompanying drawings preferred embodiment of the present utility model is described in detail, so that advantage of the present utility model
Can be easier to be readily appreciated by one skilled in the art with feature, thus make apparent clear and definite to protection domain of the present utility model
Define.
Refer to Fig. 1 and Fig. 2, the utility model embodiment includes:
A kind of extensor tendon stop fixator, comprising: fix bar 1 and screw 3, described fix bar 1 is in door font, fix bar 1
Including cross bar and the montant being fixed on cross bar two ends, it is obliquely installed between montant and cross bar, montant two ends are provided with retainer ring 2, Gu
Determine to have screw hole on ring 2, screw hole is eccentric orfice, and tightening fix bar during screw has pressurization；Described screw 3 has two,
Screw is cancellous bone screw, and two cancellous bone screws are separately positioned on the screw in the hole of retainer ring 2.Can design according to referring to body size
Different model fix bar and screw, fix bar pushes down extensor tendon in stop, and two ends screw-driving realizes fixation.
Extensor tendon stop ruptures, the no obvious defect of the tendon broken ends of fractured bone, cuts skin and exposes the tendon stop broken ends of fractured bone, stings and stop except tendon
The a little sclerotin of point.Reset extensor tendon stop when nearly interphalangeal joint flexing position, remote interphalangeal joint are stretched, then selects suitable size
Fixator, fix bar pushes down extensor tendon stop, and two ends screw-driving fixes extensor tendon stop, skin suture；Postoperative cooperation
Tool braking, nearly interphalangeal joint flexing position, remote interphalangeal joint stretch position；Fixing beginning functional training except going for postoperative 6 weeks.Fixator
Can not take out, extensor tendon fixator meets tendon stop wire and rebuilds, reduce suture prevention knot reaction, screw fixed-direction
Vertical with the tendon line of force, postoperative be difficult to loosen, screw position lean on both sides, it is to avoid top pressure extensor tendon stop dorsal skin.
The foregoing is only embodiment of the present utility model, not thereby limit the scope of the claims of the present utility model, every
The equivalent structure made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in other related technology
Field, is all included in the same manner in scope of patent protection of the present utility model.
