Abstract
One end of a kind of stitching unstrument of suture rotator cuff tear disclosed by the invention, including connecting rod, connecting rod is provided with handle, and the other end of connecting rod is provided with needle point, and needle point is equipped with cable-through hole, hanging wire stake is additionally provided on the side wall of connecting rod.The stitching unstrument of the present invention not only facilitated patient to operate, but also cheap, did not also need expensive PDS lines, greatly shortened operating time up to 2 hours；Operating difficulty can be reduced, risk caused by operation is reduced and mitigates patient suffering, convenient for carrying out in the whole nation.
Description
Technical field
The invention belongs to the field of medical instrument technology, and in particular to a kind of stitching unstrument of suture rotator cuff tear.
Background technology
To about 30~80 years old adult the study found that>The rotator cuff injury of 50 years old persons obviously increases, to ＞ at 70 years old
Up to 80% when 50%, 80 years old, as patient age ＞ 60 years old, the incidence of rotator cuff injury was about 54%, wherein huge shoulder sleeve damage
Wound accounts for 10%~40%.According to the tear(ing) strength that shoulder is tucked inside the sleeve, it is divided into part tearing and holostrome tearing.Part tearing is divided into as upper surface
Tearing in tearing (i.e. acromion face is torn), lower surface tearing (i.e. articular surface is torn) and tendon；Burkhart tears shoulder sleeve holostrome
It is divided into crescent, U-shaped, L-shaped tearing and huge rotator cuff tear (＞ 5cm) according to shape.
The treatment of rotator cuff injury can be relieved pain using non-operative treatment, or even restore the piecemeal activity of shoulder joint
Degree, but for the decline of muscular strength without positive effect, late result is poor.The treatment for the treatment of rotator cuff tear is by previous incision hand at present
Art has been gradually transitions total joint arthroscopic diagnosis, and has obtained the effect become better and better.The mode of common shoulder sleeve repairing includes wearing bone
Technique for fixing, single technology, the double technology of tradition and the suture double suturing skill of bridge.Double suture can increase tendon bone contact surface
Product reduces shoulder sleeve crack and is formed, and increases the maximum failure load of suture and provides stronger initial biomechanical strength, relatively
In it is single suture and wear skeletal fixation shoulder tuck inside the sleeve stop coverage rate higher, but either it is double suture or suture bridge technique for fixing
More pieces of holdfasts are required to, and can how holdfast buttock line could pass through shoulder to tuck inside the sleeve as early as possible, the major obstacles that just popularized at the operation.
Although there is various sutures to hook at present, suture shoulder sleeve is time-consuming and laborious, is up to several hours, patient sometimes
Anesthetic risks increase, the labor intensity of patient increases, and is unfavorable for the development of this operation；Although and there are producer's production in foreign countries
Go out a kind of convenient instrument of suture, but expensive, is unfavorable for carrying out.
Invention content
The purpose of the present invention is to provide a kind of stitching unstruments of suture rotator cuff tear, can reduce operating difficulty, reduce hand
Risk caused by art simultaneously mitigates patient suffering.
The technical solution adopted in the present invention is：A kind of stitching unstrument of suture rotator cuff tear, including connecting rod, connecting rod
One end is provided with handle, and the other end of connecting rod is provided with needle point, and needle point is equipped with cable-through hole, is additionally provided on the side wall of connecting rod
Hanging wire stake.
The features of the present invention also characterized in that：
The shape of needle point is linear, and the angle α between the axis and connecting rod axis of needle point is 45 °.
The shape of needle point is crescent.
Needle point is located at the both sides of connecting rod, bottom circular arc tangential line and company of the needle point with connecting rod junction with hanging wire stake
Angle β between extension bar axis is 45 °.
Needle point is located at the homonymy of connecting rod, bottom circular arc tangential line and company of the needle point with connecting rod junction with hanging wire stake
Angle β between extension bar axis is 45 °.
Angle γ between hanging wire stake and connecting rod is 20 °~50 °.
The beneficial effects of the invention are as follows：The stitching unstrument not only facilitated patient to operate, but also cheap, did not also need costliness
PDS lines greatly shortened operating time up to 2 hours；Operating difficulty can be reduced, risk caused by operation is reduced and is mitigated
Patient suffering, convenient for carrying out in the whole nation.

Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode the present invention is described in detail.
The present invention provides a kind of stitching unstruments of suture rotator cuff tear, including connecting rod 2, one end of connecting rod 2 to be provided with
The other end of handle 1, connecting rod 2 is provided with needle point 3, and needle point 3 is equipped with cable-through hole 4, hanging wire is additionally provided on the side wall of connecting rod 2
Stake 5.
As shown in Figure 1, the shape of needle point 3 is linear, needle point 3 is located at the homonymy of connecting rod 2, needle with hanging wire stake 5
Angle α 6 between 2 axis of axis and connecting rod of point 3 is 45 °.
The shape of needle point 3 is crescent.
As shown in Fig. 2, needle point 3 is located at the both sides of connecting rod 2, needle point 3 and 2 junction of connecting rod with hanging wire stake 5
Angle β 7 between 2 axis of bottom circular arc tangential line and connecting rod is 45 °.
As shown in figure 3, needle point 3 is located at the homonymy of connecting rod 2, needle point 3 and 2 junction of connecting rod with hanging wire stake 5
Angle β 7 between 2 axis of bottom circular arc tangential line and connecting rod is 45 °.
Angle γ 8 between hanging wire stake 5 and connecting rod 2 is 20 °~50 °.
When operation, under the monitoring of arthroscope, line is bypassed first the band string holes 4 of stitching unstrument, two line tail ends of doubling are tied up
In hanging wire stake 5, is tucked inside the sleeve across shoulder with the stitching unstrument with line, then unclamp the line in hanging wire stake 5, line is then stayed in articular cavity
In, then shoulder sleeve on the buttock line band of holdfast, is directly pulled through, knotting fixation is carried out, operation terminates.
It is an advantage of the invention that：The stitching unstrument not only facilitated patient to operate, but also cheap, did not also need expensive PDS lines,
Greatly shorten operating time up to 2 hours；Operating difficulty can be reduced, risk caused by operation is reduced and mitigates patient's pain
Hardship, convenient for carrying out in the whole nation.
