Description

Reduce tension is sewed up 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 silica gel pipeline.

Background technology

In surgical operation, often there is skin tissue defects, or because limds edema causes wound suture tension force higher after injuring operation outward, be difficult to the closed even directly situation of closure of wound.Conventionally adopt in this case 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 object 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 tension force otch, can adopt the common silk suture of 3-0 or 4-0, to reach the object of closure of wound.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, adopt clinically at present thicker stitching thread to sew up more temporarily, drawing wound, reduces wound surface as far as possible, waits for that limb swelling disappears, and after traumatic infection control, row is finally sewed up or is carried out closed wound surface by skin grafting again.But its physics anti-tensile of the suture of current clinical use is limited in one's ability, lacks flexibility, for the wound of serious edema, even causes local compression and cause cutaneous necrosis.

Summary of the invention

While the present invention is directed to current 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 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 puncture needle direct forming.

Further, we also disclose described inverted trapezoidal platform for 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, lower surface diameter is corresponding with puncture needle diameter.Certainly this inverted trapezoidal platform can be used 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 surgeon produces to operation operator.So-called puncture needle itself is the needle structure having in general sense, and its 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, cut off unnecessary silica gel pipeline after stitching, knotting is fixing.And connective stability is good between silica gel pipeline and puncture needle, the safety problems such as difficult generation comes off, slippage; This mode interface smooth, realizes smoothness and the stability similar to integral structure.
