Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of bone fixator.
Background technique
Currently, orthopaedics is various types of steel plates for fracture inside-fixture, such as: general steel plate, compression steel plate lock steel
Plate；Need to be divided into upper limb, lower limb and all kinds of dissection armor plates because of fracture again, steel plate type is more, and because needing to fracture
Open reduction is carried out, damage is larger, is not easy Micro-operation, and because of the variation of skeletal shape, and steel plate is bonded bad, fixation with bone
Effect is impacted, and the fixed fracture of plate screw cannot reach because fixed nail hole direction is unilateral, single side fixed structure to bone
The solid of folding is fixed, and Yi Fasheng steel plate fractures, Bone nonunion, disunion.
Summary of the invention
The purpose of the present invention is to solve when existing fracture operation, usually occurring because fracture site bone block is small, often at present
Screw diameter is big, the problem that can not properly fix, especially in the fracture of joint part, it is desirable that anatomical reduction, strong solid
Fixed, existing implant is unable to satisfy the requirement of such operation, and the method for the current international practice is that thin Kirschner wire is used in art at present
It is fixed temporarily, then penetrates screw by several pieces of screw holes existing on steel plate, the frictional force by the opposite pressurization between bone block is solid
Fixed small bone block, it is postoperative to be lost it is often found that resetting, the problems such as fixation failure, provide a kind of bone fixator.
To achieve the above object, the technical scheme adopted by the invention is that: a kind of bone fixator, including elastic hollow
Tucker staple, locking steel plate, sleeve and Kirschner wire, the locking steel plate are equipped with what multiple and elastic hollow tucker staple matched
Nail hole, elastic hollow tucker staple are fixed in nail hole, and the center of the elastic hollow tucker staple, which is equipped with, to be run through in above and below it
Heart hole, the Kirschner wire penetrate elastic hollow tucker staple by centre bore, and one end of Kirschner wire passes through elastic hollow tucker staple
It is fixed on locking steel plate, the other end is fixed after passing through bone by sleeve, is uniformly opened at the top of the elastic hollow tucker staple
Equipped with multiple upper grooves, bottom is uniformly provided with multiple lower grooves, and the upper groove and lower groove are arranged in a staggered manner, and upper groove
It is connected to centre bore with lower groove, the bushing core is equipped with through the Kirschner wire fixation hole of sleeve, the sleeve two
Side is equipped with the threaded hole perpendicular to Kirschner wire fixation hole, and Kirschner wire fixation hole is connected with threaded hole, in the threaded hole
Equipped with holding screw.
Preferably, the elastic hollow tucker staple is the hollow tucker staple of elastane thread, and the nail hole is threaded hole.
Preferably, the center-hole diameter of the elastic hollow tucker staple is consistent with Kirschner wire diameter.
Preferably, the upper groove and lower groove are six.
Preferably, the elastic hollow tucker staple, locking steel plate, sleeve are consistent with Kirschner wire material selection.
Preferably, the material of the elastic hollow tucker staple, locking steel plate, sleeve and Kirschner wire is stainless steel.
Preferably, the center line of the threaded hole of the sleeve two sides is not in the same horizontal line.
Preferably, the sleeve is integrally formed by cylindrical type cylinder and disc base.
Preferably, the diameter of the disc base is twice of cylindrical type barrel diameter.
After adopting the above technical scheme, when a kind of bone fixator work of the invention, needed for locking steel plate is placed in
Position, elastic hollow tucker staple is placed in nail hole, then Kirschner wire is placed in the centre bore of elastic hollow tucker staple, fixed
After good position, elastic hollow tucker staple is squeezed into the nail hole of locking steel plate, elastic hollow tucker staple lower notches generate receipts
Contracting, and be independent of each other, fixation Kel's needle, the Kirschner wire other end passes through bone and is fixed by sleeve.
Elastic hollow tucker staple of the invention allows to penetrate the thin Kirschner wires such as 1.0,1.5 in small bone block, and one end passes through
Elastic hollow tucker staple is fixed on locking steel plate, and the other end is fixed using sleeve, can be firmly solid by the small bone block of reset
It is scheduled on locking steel plate；And the direction that Kirschner wire penetrates, selection selection can be adjusted according to classification of fracture when penetrating Kirschner wire
The adjustable pressurization of any direction, it might even be possible to reach cerclage effect, improve operation accuracy, improve operation acceptance rate, reduce
Disability rate due to wound.
In conclusion be that fracture selects combination bone fixator the invention has the following advantages: structure is simple,
Easy to use, operation is easy to grasp；Realize two-sided fixation, it is firm firm, it can avoid Plate break, Bone nonunion, solid failure
Etc. risks, be beneficial to the recovery of sufferer bone；Suitable for Micro-operation, damage is smaller, easy to promote and utilize.
