The problem of blood fortune is poor, therefore there is also notch disunion.Aiming at the problem that cutting suturing skill, have been developed that using use
Minimal invasive techniques suture heel string, and notch is small, and greatly shorten operating time.Minimally invasive suture utilizes sponge holding forceps or micro- more at present
Wound stitching unstrument is sutured, and current minimally invasive stitching unstrument is more approximate with the present invention, but the minimally invasive stitching unstrument design of former heel string is simple,
It is only capable of simply being sutured under the conditions of minimally invasive, the disadvantage is that suture strength is not good enough.The present invention is the minimally invasive reinforcement stitching unstrument of heel string,
Purpose is to carry out high-intensitive suture to heel string under small notch.Purpose is as to reach high as possible to heel string under the conditions of minimally invasive
The purpose of intensity suture.
Also there is the stitching unstrument sutured using small notch to heel string both at home and abroad at present.But the technology of existing stitching unstrument
Feature: 1, band radian or radian do not meet human figure to main frame, are difficult to accurately position under the conditions of minimally invasive；2, it is divided into
Multiple components assemble, and need to re-assembly before surgical procedure, and complicated and consuming time, components are easily lost.3, needle
Hole design is simple, can only simply be sutured under the conditions of minimally invasive, suture strength is lower.Therefore, because suture way is simple, seam
It is small to close intensity, disconnected rate is high again for heel string.So needing a kind of novel heel string stitching unstrument, operation can be reduced by using the instrument and cut
Mouth and wound reduce infection probability, shorten operating time, achieve the purpose that minimally invasive suture, while again can be under conditions of minimally invasive
Reinforce the suture strength of heel string, reduces the probability that heel string is broken again.
Summary of the invention
The minimally invasive purpose for reinforcing stitching unstrument: 1, main frame bending-type designs, and meets human dissection form, unobstructed to enter people
Body；2, integral type assembles, and structure is simple；3, pin hole assembled arrangement realizes high-intensitive suture under the conditions of minimally invasive.
To solve the above-mentioned problems, the utility model provides a kind of minimally invasive stitching unstrument of heel string on one side comprising outer
The fixed device of frame, heel string, telescopic device and handle are constituted；
The telescopic device includes left and right drive screw, handwheel and locating shaft, wherein left and right drive screw is fixed on outline border
Inside frame, locating shaft is parallel to left and right drive screw and is set to inside outer framework, and the middle part of left and right drive screw is arranged in handwheel,
And be fixedly connected with left and right drive screw, the screw thread being arranged on the drive screw of left and right is reversed in handwheel two sides, handwheel
Side be dextrorotation, the other side is derotation；
The fixed device of the heel string includes 2 fixed with taking off fork, wherein 2 fixations are separately positioned on handwheel with taking off to pitch
Two sides, fixed with the tail portion for taking off fork includes the screw thread being engaged with left and right drive screw side screw, and positioning used for positioning
Axis passes through and takes off fork, and the front end for taking off fork is provided with the fixing head of fixed heel string；
The outer framework has the radian of 100-160 degree；
The handle is fixedly connected with outer framework.
In a technical solution of the utility model, fixed use is taken off between the tail portion of fork and fixing head with 100-
160 degree of radian.
In a technical solution of the utility model, the fixing head is long cyclic annular.
In a technical solution of the utility model, position corresponding with fixing head, side are set on the outer framework
It is equipped at least four pin hole, the other side is long cyclic annular.
In a technical solution of the utility model, position corresponding with fixing head, side are set on the outer framework
It is equipped at least six pin hole, the other side is long cyclic annular.
In a technical solution of the utility model, the width of the outer framework is 5cm-10cm.
In a technical solution of the utility model, the outer framework has the radian of 120-140 degree, the fixed use
Take off the radian between the tail portion of fork and fixing head with 120-140 degree；The radian of outer framework and fixation are used the tail portion for taking off fork and are consolidated
The radian determined between head is identical.
The fixed device of heel string is entered in vivo along small notch when in use, it is solid according to heel string width adjustment by telescopic device
Determine device width, the fixed heel string broken ends of fractured bone left and right sides, for suture of threading a needle in vitro.
The left and right width of the fixed device of telescopic device rotation adjustment heel string, guarantees the fixation of the different in width heel string broken ends of fractured bone.
Outer framework formed camber line, meet structoure of the human body, be convenient in vitro operation, while can allow the more preferable control of surgical doctor with
Tendon reinforces stitching devices.
