Description
Technical field
This utility model belongs to technical field of medical instruments, relates to a kind of band wire holdfast, and a kind of holdfast suture instrument with this band wire holdfast.
Background technology
In the time that soft tissue tears off and need to repair from skeleton, the soft tissue that conventionally needs surgeon to separate with stitching thread reparation, stitching thread is attached to skeleton by holdfast.After the implanted skeleton of holdfast, stitching thread passes soft tissue that will be again attached, then attaches a suture on holdfast with suitable tension force.
In prior art, the afterbody of holdfast is fixed with thimble, and stitching thread passes from thimble, and is finally fixed on thimble.Adopt this kind of mode can only fix a stitching thread, if need to be from multiple directions reparation or fixing soft tissue time, must use multiple holdfasts, this has just increased wound face, makes operation process complexity; In addition, in the process of walking, there is the risk of being cut off by thimble in stitching thread, once stitching thread comes off from holdfast, this holdfast just cancels, and need to implant new holdfast, causes the wasting of resources, and has increased wound face, increases misery to patient, has extended operating time.
Utility model content
For solving the above deficiency existing in prior art, this utility model provides a kind of band wire holdfast, and its Wire channel in building can be fixed many stitching thread simultaneously, has reduced the risk that holdfast cancels, and has reduced cost; And this band wire holdfast is implanted after skeleton, and open bottom, has strengthened the hold of holdfast;
Another object of the present utility model, is to provide a kind of holdfast suture instrument with above-mentioned band wire holdfast.
For achieving the above object, the technical scheme that this utility model adopts is as follows:
A kind of band wire holdfast, comprises holdfast body, and described holdfast body is provided with through hole along its above-below direction;
The bottom of holdfast body has at least two Wire channel in building for stitching thread is walked;
After described holdfast body is implanted in skeleton, the bottom of holdfast body can be opened with respect to holdfast body.
As to restriction of the present utility model, on the outer wall of described holdfast body, be fixed with multiple projections for contacting with skeleton.
As another kind of the present utility model is limited, described through hole is the structure of connection bottom, upper post hole taper hole, and the radial dimension of described taper hole is gradually little from top to bottom.
As to of the present utility model the third limit, on described through-hole wall with female thread.
This utility model provides a kind of holdfast suture instrument simultaneously, comprises stitching thread, and the band wire holdfast of aforementioned structure;
This holdfast suture instrument also comprises for holdfast body being implanted to precession spanner in skeleton, for the holdfast body bottom of rushing to summit so that the expansion spanner that open holdfast body bottom;
Described sutural two ends pass from two Wire channel in building respectively.
As the restriction to aforesaid way, the precession handle that described precession spanner comprises external diameter and the suitable precession bar of through hole internal diameter, connects firmly with precession masthead portion.
As further restriction:
On the outer wall of described precession bar with external screw thread.
On the outer wall of described precession bar, be fixedly connected with thimble.
As further limiting again, the expansion hands handle that described expansion spanner comprises expanding bar, connects firmly with expanding bar top; The external diameter of described expanding bar is greater than the minimum diameter of taper hole, is less than or equal to the internal diameter in post hole.
The use procedure of holdfast suture instrument of the present utility model is as follows:
First in the skeleton place perforate that has soft tissue to depart from, holdfast body is placed in to aperture place, hole and holdfast body interference fit, then use precession spanner, precession bar is screwed in the through hole of holdfast body, due to precession bar and holdfast body threaded engagement, rotation precession handle, holdfast body will move down, and finally implants in skeleton, then precession bar is screwed out from through hole; Then use expansion spanner, expanding bar is placed in to through hole, expansion spanner is applied to downward external force, the bottom taper hole of through hole is just expanded, and the hold of holdfast body is strengthened, and then expansion spanner is exited from through hole; Now complete holdfast body and implant the work of skeleton; Finally pass and want attached soft tissue with stitching thread, then attach a suture on holdfast body.
Owing to having adopted technique scheme, compared with prior art, obtained technological progress is this utility model:
1. Wire channel in building of the present utility model can be fixed many stitching thread simultaneously, has avoided stitching thread to come off from holdfast body, and the phenomenon that holdfast body cancels, has reduced operation cost; Holdfast body is implanted after skeleton in addition, because bottom can be opened with respect to holdfast body, and then has strengthened the hold of holdfast;
2. the projection on holdfast body outer wall, for contacting with skeleton, can grow into skeleton, increases the frictional force between holdfast body and skeleton, makes skeleton Fast Growth;
3. through hole is the structure of connection bottom, upper post hole taper hole, and in the time that holdfast body is applied to downward external force, the structure of taper hole more easily realizes bottom and opens with respect to top;
4. precession spanner of the present utility model is for holdfast body is implanted in skeleton, expansion spanner be used for rushing to summit holdfast body bottom so that holdfast body bottom open.
Band wire holdfast of the present utility model and holdfast suture instrument are suitable for makes medical apparatus and instruments, and band wire holdfast is for reconnecting the soft tissues such as the tendon ligament of separation and skeleton.
