Description
Technical field
The present invention relates to surgical operating instrument technical fields, and phalanx bone is used for when being specifically operative treatment phalangeal fracture
Fixed fixator and silk-thread fixator are corrected at folding.
Background technique
Hammer finger is that the violent buckling of finger causes extensor tendon stop to tear or cause at phalangette extensor tendon attachment
Avulsion fracture cannot be stretched actively to digital tip flexion deformity occur.It is clinically divided into according to type of impairment as bone hammer
Shape refers to (extensor tendon distal end is together with phalangette base portion avulsion fracture) and tendon hammer finger (simple extensor tendon tip breakages).Outside
Surgical treatment is a kind of important means for treating hammer finger.It is existing subsidiary for the tearing of extensor tendon stop or tendon smaller
The tearing of sclerite, operation penetrate phalanges using Kirschner wire is oblique, and the distal phalanx basal part brill two by osteocomma two sides is small
Fixed silk thread of performing the operation (existing is often nylon wire) is passed through aperture and crosses the fixed osteocomma in stop portion of extensor tendon, operation by hole
Fixed silk thread both ends are pierced by finger face, and fixed silk thread both ends of performing the operation are auxiliarily fixed using button, to reach fixed silk thread effect of performing the operation
In fracture.But it is auxiliarily fixed using button, there are fixed poor reliability, button is easy to close with face paste is referred to, influences the hand of patient
The healing of art position；It is additionally present of defect that is inconvenient, and fixing poor reliability, while cannot achieve and fracture is applied controllably
Tension, to cause surgical effect undesirable, healing process of tendons is difficult, and failure rate is high.In addition, solid as operation using nylon wire
Fixed thread line, nylon line tension is big, is easy to loosen for a long time.
Summary of the invention
Objects of the present invention: to overcome defect of the existing technology, the present invention provides a kind of operation fixed wire line end
Be fixed conveniently reliable hammer finger deformity extensor tendon stop of head rebuilds orthoses, and the fixed impetus of operation fixed wire line end is made
For Kirschner wire end point, have and Kirschner wire effect is auxiliarily fixed, good operation effect improves postoperation recovery effect.
To achieve the above object, the present invention provides the following technical scheme that
A kind of hammer finger deformity extensor tendon stop rebuilds orthoses, refers to back including passing through and refers to the Kirschner wire in face and be fixed on hand
The fixed silk thread of operation on finger, fixed silk thread both ends of performing the operation are the fixing end for being piercing in Fingers face, and fixed silk thread of performing the operation is consolidated
Fixed end is combined with silk-thread fixator, it is characterised in that: the Kirschner wire has across the bending for referring to face and transverse fold is formed
End, the silk-thread fixator are supported in bending end point.
By using above-mentioned technical proposal, silk-thread fixator is supported on Kirschner wire, avoids referring to that face paste is closed with patient, and silk
Line fixator is supported through Kirschner wire and is fixed, the operation for facilitating fixed silk thread of performing the operation to be fixed on silk-thread fixator, and bending end is same
When with avoid operation fixed wire line formed tension force effect Kirschner wire on, cause Kirschner wire pressurize after slide.
Preferably, the silk-thread fixator includes the matrix for being fixedly supported to bending end point, is had on matrix for operation
The guide through hole and be equipped with the retracting pressing mechanism fixed for the fixing end for fixed silk thread of performing the operation, retracting that fixed silk thread passes through
Pressing mechanism includes shaft and the shaft lock with the cooperation of shaft locking, and matrix, which is equipped with, to be cooperated for shaft locating rotation
Axis hole, the shaft are rotatably assorted on matrix, and there is shaft fixed perform the operation to fix silk thread fixing end and furl operation fixed wire
The retracting shaft part of line and for furl operation operating side.Under structure design, shaft realizes the fixation for fixed silk thread of performing the operation
End is fixed, and rotating shaft realizes that the tension to operation fixed wire line realizes that tension is controllable, to improve surgical effect, improves patient
Healing effect.
Preferably, the mode that the shaft is axially movable is assemblied on matrix, and the shaft lock is with shaft axial direction
It is mobile to constitute locking, unlock cooperation on direction of rotation between shaft and corresponding axis hole.It is easy to operate with simple and compact for structure
The advantages of.
Preferably, the shaft consolidates that lock includes that the internal lock that is fixedly installed in axis hole is fixed and fixing sleeve is loaded on turning
External lock on axis is fixed, and the fixed fixed ring including being fixed in axis hole of the internal lock, fixed ring is axially extending to be had by several edges
The circumferential elasticity arranged at equal intervals clasps the elastic jacket that piece surrounds, and elastic jacket is relative to connecting the another of one end with fixed ring
End is the locking end that elastic can gather, open, and interval forms annular chamber between the outer circumferential sides and axis hole wall of elastic jacket, described
