Operation relaxation suture silica gel pipelineTechnical field
The present invention relates to medical instruments field, particularly relate to surgery instrument, more specifically relate to operation relaxation suture silica gel pipeline.
Background technology
In surgical operation, often there is skin tissue defects, or because injure operated hind limb body edema outward and cause wound suture tension force higher, be difficult to closed even cannot the situation of direct closure of wound.In this case usually adopt tension suture method to reduce wound surface as far as possible or reduce skin to shrink back.
So-called tension suture be used in both sides skin tension too large time wound suture, object prevents wound dehiscence, or as far as possible by sewing up the exposure reducing deep tissue.For limbs operation, normal no-station pole canopy 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 closed in skin nature tension range.But as run into limbs serious swelling after wound, to cut after skin because skin bounces back to both sides naturally, wound can be caused to sew up, thus cause the muscle in deep, nerve, blood vessel even skeleton expose.Certainly, the skin injury that area is larger also can cause wound directly not close.For above-mentioned situation, the thicker stitching thread of many employings is sewed up temporarily clinically at present, and drawing wound as far as possible reduces wound surface, waits for that limb swelling disappears, and after traumatic infection control, row is finally sewed up or carried out closed wound surface by skin grafting again.But its physics tensile energy of suture of Clinical practice is limited at present, and lack flexibility, the wound for Severe edema even causes local compression and causes cutaneous necrosis.
Summary of the invention
When the present invention is directed to current tension suture, the situation that particularly, wound both sides skin tension is excessive, general stitching thread pulling force is inadequate, and easily causes skin compression, downright bad problem after sewing up, and creatively provides a kind of brand-new operation relaxation suture silica gel pipeline.

Medical silicone tube adopts extrusion molding continuous sulfurizing, extruding, forming and vulcanization tank sulfuration method or molded vulcanization method to make, be generally used for food medical apparatus and instruments, on respirator, medical water conservancy diversion or the equipment such as medical analytical instrument, hemostasis instrument, effect concentrates on conduction, the circulation of liquid or class I liquid I.
Creatively utilize it to use as tension suture line in the present invention, but let us find due to it it is generally make land used as carrier pipe, so not as sutural speciality in its structure, need to use the aids such as scalpel, form puncture duct, operation inconvenience, and wound is larger.
In order to address this problem, we refer to this structure of puncture needle, and by puncture needle together with silica gel pipeline effectively secure bond.Without the need to by other operation tools, just can realize sewing up, ensure in sewing process, the stationarity between silica gel pipeline and puncture needle simultaneously, improve operation safety.
Due to silica gel tube and puncture needle material totally different, cannot be integrally formed, we further disclose fixed structure that is a kind of and integrative-structure stability basic simlarity, the link of described puncture needle and silica gel pipeline is inverted trapezoidal platform structure, the base angle of described inverted trapezoidal platform is 120 ° ~ 130 °, and the upper bottom surface of described inverted trapezoidal platform is circle.
Here so-called inverted trapezoidal platform structure, refer to that its one end of comparatively expanding is near free end, comparatively little one end near silica gel pipeline, thus had both facilitated the property easy for installation of silica gel pipeline and puncture needle, can ensure again the stability that silica gel pipeline is fixed with puncture needle structure after fixation.
Further, the link that the present invention further discloses described puncture needle is three grades of inverted trapezoidal platform structures, and the inverted trapezoidal platform identical by three sizes is formed by stacking.Namely form three grades of inverted trapezoidal platform structures.Thus can better ensure the stability between rear silica gel pipeline and puncture needle is installed.
Here so-called superimposed be superimposed in moulding, it is all for being formed by puncture needle direct forming.
Further, we also disclosed described inverted trapezoidal platform for height 0.4mm, lower surface diameter 0.2cm, 0.25cm, 0.3cm, 0.35cm, 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 alone, and also can multiplely gather into folds use.
Further, the free end of described puncture needle is angle knife-edge puncture needle.Avoid the potential risk that simple sharp metal needle point produces operator and surgeon.Namely so-called puncture needle itself is the needle structure had in general sense, and its one end is stiff end, and in cylindric, 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 being opened in 6cm pin end tip is formed.
Improve as another kind, the diameter we disclosing 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 the need to 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, not easily produce come off, the safety problem such as slippage; This mode interface smooth, realizes the smoothness similar to integral structure and stability.
