Abstract

The utility model discloses an augmentation rhinoplasty prosthesis fixing suture device which comprises a needle push clamp and a suture needle, wherein the needle push clamp consists of a clamp handle I, a clamp handle II, a jaw I and a jaw II, the clamp handle I and the clamp handle II are mutually hinged, the jaw I is arranged at the front end of the clamp handle I, and the jaw II is arranged at the front end of the clamp handle II. A needle push hole which is used for placing the tail of the suture needle is formed in the jaw I, a line entering hole which used for a suture line to penetrate through is formed in the bottom of the needle push hole, and a needle entering hole which is used for the suture needle to penetrate through is formed in the jaw II. When used, the suture needle is pushed by the needle push hole of the jaw I, and sequentially penetrates through prosthesis, human tissue and the needle entering hole, suture is completed. The augmentation rhinoplasty prosthesis fixing suture device is convenient to use, the prosthesis can be firmly fixed without the need for exposing surgery view so as to prevent displacement. In addition, clamping for the suture needle can be formed by an elastic needle entering hole so as to ensure that the suture needle is reserved on the jaw II and taken away after suture, and knotting operation is convenient to conduct.

Description

The augmentation rhinoplasty prosthese is stitching devices fixedly

Technical field

This utility model relates to medical instruments field, particularly a kind of stitching devices of nose augmentation prosthesis.

Background technology

It is common plastic surgery operations that augmentation rhinoplasty is performed the operation, and mainly contains injection augmentation rhinoplasty, prosthese augmentation rhinoplasty dual mode, for prosthese augmentation rhinoplasty mode, needs to paste the lacuna that nasal bone separates the placement prosthese behind incision nose pillar or the Departmentofplastica.dreconstructivesurgery.

In the prior art, after prosthese is put into above-mentioned lacuna, because the operation technique space is less, be not easy to sew up and the operation such as stitching thread knotting, generally do not take to sew up fixation, cause prosthese the problems such as displacement easily to occur.

For above-mentioned deficiency, need to explore a kind ofly for the fixing stitching devices of augmentation rhinoplasty operation prosthese, so that prosthese is sewed up fixing, prevent the problems such as displacement.

The utility model content

In view of this, this utility model provides fixedly stitching devices of a kind of augmentation rhinoplasty prosthese, and this device can be sewed up fixing in less working place to nose augmentation prosthesis, solves existing prosthese and is difficult for sewing up the fixing technical problem that displacement easily occurs.

This utility model solves the problems of the technologies described above by following technological means:

Augmentation rhinoplasty prosthese of the present utility model is stitching devices fixedly, comprise push pin pincers and sewing needle, the described pincers of pushing pin comprise the clamp handle I, the clamp handle II that are hinged, be arranged at the jaw I of clamp handle I front end and be arranged at the jaw II of clamp handle II front end, described jaw I inboard is provided for the hole of pushing pin that the sewing needle backshank is put into, push pin hole bottom is provided for the entrance hole that stitching thread passes, and is provided for the inserting needle hole that sewing needle passes on the described jaw II.

Further, described inserting needle hole is the springhole that diameter can increase, and the diameter of needle passing hole is less than the diameter of sewing needle.

Further, the inwall in described inserting needle hole is along circumferentially being provided with shell fragment.

Further, described inserting needle hole is embedded with resilient sleeve.

The beneficial effects of the utility model: augmentation rhinoplasty prosthese of the present utility model is stitching devices fixedly, comprise push pin pincers and sewing needle, the described pincers of pushing pin comprise the clamp handle I that is hinged, clamp handle II, be arranged at the jaw I and the jaw II that is arranged at clamp handle II front end of clamp handle I front end, described jaw I inboard is provided for the hole of pushing pin that the sewing needle backshank is put into, push pin hole bottom is provided for the entrance hole that stitching thread passes, be provided for the inserting needle hole that sewing needle passes on the described jaw II, during use, sewing needle promotes by the hole of pushing pin of jaw I, pass successively prosthese, tissue and inserting needle hole, finish stitching, easy to use, need not to expose surgical field of view, can make prosthese fixing more firm, prevent displacement, in addition, can form clamping to sewing needle by elastic inserting needle hole, guarantee to be retained in after sewing needle is sewed up jaw II upper and take the operation of being convenient to tie a knot out of by it.

Description of drawings

Below in conjunction with drawings and Examples this utility model is further described.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the A place enlarged drawing of Fig. 1, and the inserting needle hole is elastic piece structure;

Fig. 3 is the A place enlarged drawing of Fig. 1, and the inserting needle hole is elastic sleeve structure.

The specific embodiment

Below with reference to accompanying drawing this utility model is elaborated, as shown in the figure: the augmentation rhinoplasty prosthese of the present embodiment is stitching devices fixedly, comprise push pin pincers and sewing needle 1, the described pincers of pushing pin comprise the clamp handle I2 that is hinged, clamp handle II 3, be arranged at the jaw I 4 and the jaw II 5 that is arranged at clamp handle II 3 front ends of clamp handle I 2 front ends, the present embodiment adopts the long pincers of pushing pin of jaw, so that entering darker position, jaw sews up, described jaw I 4 inboards are provided for the hole 4a that pushes pin that sewing needle 1 backshank is put into, push pin hole 4a bottom is provided for the entrance hole 4b that stitching thread passes, be provided for the inserting needle hole 5a that sewing needle 1 passes on the described jaw II 5, when prosthese and tissue are sewed up, use push pin pincers jaw clamp prosthese edge and tissue, sewing needle passes the prosthese edge successively under the promotion in the hole of pushing pin, tissue and inserting needle hole are pulled out sewing needle knotting again and can be finished stitching.

As further improvement in the technical proposal, described inserting needle hole 5a is the springhole that diameter can increase, the diameter of inserting needle hole 5a is less than the diameter of sewing needle 1, when sewing needle enters the inserting needle hole, expanded in the inserting needle hole, simultaneously, the elasticity in inserting needle hole forms clamping action to sewing up pin, conveniently sewing needle is taken out of.

As further improvement in the technical proposal, the inwall of described inserting needle hole 5a is along circumferentially being provided with shell fragment 6, and the shell fragment distortion can increase the inserting needle bore dia, allows sewing needle pass through, and simultaneously, the restoring force of shell fragment can form the clamping to sewing needle, and is simple in structure.Certainly, also can adopt another kind of mode, described inserting needle 5a hole is embedded with resilient sleeve 7, and sewing needle passes resilient sleeve after the resilient sleeve also can form clamping action to sewing needle, can realize the purpose of this utility model equally.

Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment this utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
