Abstract

The invention relates to the field of medical apparatuses and instruments, in particular to an instrument for operation, namely a novel operation relaxation suture silica gel pipeline. The problem that currently, during relaxation suture, especially under the condition that tension of skin on the two sides of a wound is too large, pulling force of a common suture line is not enough, and the skin can be easily pressed and be necrotic can be solved. The novel operation relaxation suture silica gel pipeline comprises a silica gel pipeline body and puncture needles which are fixedly connected at the two ends of the silica gel pipeline body respectively. According to the technical scheme, relaxation suture of the large-tension wound can be achieved, and meanwhile other auxiliary tools are of no need, after suture, a surplus silica gel pipeline is cut off, and knotting and fixing are carried out. Connecting stability between the silica gel pipeline body and the puncture needles is good, and safety problems such as falling off and sliding off cannot happen easily.

Description

Reduce tension is sewed up the silica gel pipeline

Technical field

The present invention relates to medical instruments field, particularly relate to surgery instrument, more specifically relate to Reduce tension and sew up the silica gel pipeline.

  

Background technology

In surgical operation, skin tissue defects often occurs, or, because after injuring operation outward, limds edema causes wound suture tension force higher, be difficult to the closed even directly situation of closure of wound.Usually adopt in this case the tension suture method dwindle as far as possible wound surface or reduce skin and shrink back.

So-called tension suture is to be used in the wound suture of both sides skin tension when too large, and purpose is to prevent wound dehiscence, or by stitching, reduces as far as possible the exposure of deep tissue.Take limbs operation as example, normally without the tension force otch, can adopt the common silk suture of 3-0 or 4-0, to reach the purpose of closure of wound.The small size skin injury still can reach disposable closure in skin nature tension range.But as run into limbs serious swelling after wound, cut after skin because skin bounces back to both sides naturally, can cause wound to sew up, thereby the muscle, nerve, blood vessel that cause deep even skeleton expose.Certainly, the skin injury that area is larger also can cause directly closure of wound.For above-mentioned situation, at present clinically adopt thicker stitching thread to sew up more temporarily, the drawing wound, reduce wound surface as far as possible, waits for that limb swelling disappears, and after controlling, row is final again sews up or carry out closed wound surface by skin grafting for traumatic infection.But its physics anti-tensile of the suture of present clinical use is limited in one's ability, lacks flexibility, and for the wound of serious edema, even causes local compression and causes cutaneous necrosis.

  

Summary of the invention

While the present invention is directed to present tension suture, particularly in the face of the excessive situation of wound both sides skin tension, general stitching thread pulling force is inadequate, and after sewing up, easily causes the problem of skin compressing, necrosis, creatively provides a kind of brand-new Reduce tension to sew up the silica gel pipeline.

Further, the link that the present invention also further discloses described puncture needle is three grades of inverted trapezoidal platform structures, by three identical inverted trapezoidal platforms of size, is formed by stacking.Namely form three grades of inverted trapezoidal platform structures.Thereby can better guarantee to install the stability between rear silica gel pipeline and puncture needle.

Here so-called superimposed be superimposed in moulding, it is all for being formed by the puncture needle direct forming.

Further, we also disclose described inverted trapezoidal platform and have been height 0.4mm, lower surface diameter 0.2cm, 0.25cm, 0.3cm, 0.35cm, and upper surface diameter 0.15cm, 0.20cm, 0.25cm, 0.30cm, the lower surface diameter is corresponding with the puncture needle diameter.Certainly this inverted trapezoidal platform can use separately, and use also can a plurality ofly gather into folds.

Further, the free end of described puncture needle is angle knife-edge puncture needle.Avoiding simple sharp metal needle point is the potential risk that the surgeon produces to the operation operator.So-called puncture needle itself is namely the needle structure that has in general sense, and the one end is stiff end, is cylindric, and the other end is contracted to tip-shape gradually, in order to puncture.

Further, we are on the technical scheme basis of angle knife-edge puncture needle, and further disclosing described puncture needle is by 6cm needle body, 6cm pin end, and the oblique 3cm blade that is opened in 6cm pin end tip forms.

As another kind, improve, the diameter that we disclose described puncture needle is 0.2cm, 0.25cm, 0.3cm, 0.35cm.

Adopt technical scheme disclosed in this invention, can realize the tension suture of hightension wound, simultaneously without by other assisted surgery instruments, after stitching, cut off unnecessary silica gel pipeline, knotting is fixing to be got final product.And between silica gel pipeline and puncture needle, connective stability is good, the safety problems such as difficult generation comes off, slippage; This mode interface smooth, realize smoothness and the stability similar to integral structure.
