Abstract
The utility model discloses a threading-free medical suture needle, which comprises an arc needle body, and is characterized in that a clamping groove is arranged at the tail of the needle body, and a clamping bar is obliquely arranged in one side of the clamping groove; the space between the clamping bar and the other side of the clamping groove is matched with the diameter of a medical suture, and a skidproof rack with outward inclined side and inward straight side is arranged on one side of the clamping bar opposite the other side of the clamping groove or at the inner side of the other side of the clamping groove; and optimally, a pair of barbed clamping teeth are also arranged inside the clamping groove, and two tips of the barbed clamping teeth are contacted with each other to form a closed inner groove. Compared with the prior art, with the special design of the needle tail, the medical suture needle can be pulled in but can not be pulled out, and simultaneously, a return suture can be pulled into a rack-shaped gap between the clamping bar and the other side of the clamping groove to be fixed; and accordingly, the return suture does not need to be fixed by a needle holder, so that the use is extremely convenient.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly a kind ofly exempts to wear medical suture needle.
Background technology
At present, known medical suture needle afterbody has an oval-shaped pin hole, during use stitching thread is passed pin hole, and the returning line that turns back, returning line can use after being stuck in and fixing on the needle holder.The above-mentioned medical suture needle trouble of threading a needle, the time of threading a needle is long, goes offline easily, and these problems are perplexing the speed and the quality of operation.
So, at present, how to provide a kind of threading convenient, returning line need not to carry out fixed new medical sewing needle by needle holder during threading, with regard to becoming the present technique field problem to be solved is arranged.
The utility model content
Technical problem to be solved in the utility model is, in order to overcome above-mentioned the deficiencies in the prior art, and provide a kind of need not by needle holder fixedly returning line can conveniently adorn pin exempt to wear medical suture needle.
In order to solve the problems of the technologies described above, adopted following technical scheme in this utility model:
A kind ofly exempt to wear medical suture needle, comprise arcual needle body, its characteristics are that described needle body afterbody is provided with a draw-in groove, be provided with a card article in one side of draw-in groove is oblique, spacing between described card article and the draw-in groove another side and suture diameter coupling is provided with, and the side relative with the draw-in groove another side or the inboard of draw-in groove another side are provided with the inside anti-skid rack of the outside straight flange of hypotenuse on the described card article.Wherein, spacing between described card article and the draw-in groove another side and suture diameter coupling is provided with, be meant between the two distance should be less than the suture diameter and the returning line when making that suture is threaded a needle can be fixed between the two by the tooth bar shape that is provided with.Like this, during use, suture that earlier will be to be worn is stretching, again exceptionally straight suture is firmly spurred in the draw-in groove of pin, force suture by the tooth bar shape gap between card article and the draw-in groove another side and enter into draw-in groove inside, because card article and tooth bar shape are oblique interior the setting, so the line body is mobile outwardly difficult toward interior easily mobile; Be fixed on returning line between card article and the draw-in groove another side this moment again, finishes the wiring process.
As the further optimization of technique scheme, described draw-in groove inside also is provided with a pair of fluking type latch, and two crowns of described fluking type latch contact and form the inside groove of a closure.Like this, when the suture diameter is thin, can continue to spur stitching thread during wiring, stitching thread will force and open slightly between the described fluking type latch and draw in stitching thread in the inside groove by force, because two crowns of fluking type latch are contacted state, pull out so can stop the line body to be reversed in use more effectively.
As further optimizing again of technique scheme, describedly exempt to wear medical suture needle integral body and constitute by high strength elastic material.Like this, can increase the elasticity of latch, wiring is more prone to, simultaneously owing to card article, latch are barb-shaped setting, so can not influence the maintenance effect of stitching thread in latch.
In sum, compare with prior art, this utility model adopts and draws (pressure) line body mode to make suture penetrate backshank draw-in groove or inside groove, because the particular design of backshank, suture can draw in and can not pull out, and for the practician, eyes are not seen and suture can be drawn in the pin.Simultaneously, returning line can be drawn in by the tooth bar shape gap between card article and the draw-in groove another side and fix, and so just need not to use fixedly returning line of needle holder, makes extremely easy to use.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind ofly exempt to wear medical suture needle, comprise arcual needle body 1, described needle body 1 afterbody is provided with a draw-in groove 6, be provided with a card article 2 in one side of draw-in groove 6 is oblique, spacing between described card article 2 and draw-in groove 6 another sides 3 and suture diameter coupling is provided with, and a side relative with draw-in groove 6 another sides 3 on the described card article 2 is provided with the inside anti-skid rack of the outside straight flange of hypotenuse.Wherein, the spacing between described card article 2 and draw-in groove 6 another sides 3 also specifically is set to 0.2mm less than the suture diameter.During concrete enforcement, described draw-in groove 6 inside also are provided with a pair of fluking type latch 4,5, and two crowns of described fluking type latch 4,5 contact and form the inside groove 7 of a closure.Describedly exempt to wear medical suture needle integral body and constitute by high strength elastic material; More specifically can select the stainless steel material of high strength elastic to constitute.
During this utility model wiring, an end of medical suture needle and suture will be held, an end that exposes medical suture needle backshank seam and suture, another pulls suture and puts it into draw-in groove 6 places of medical suture needle backshank, the line body is drawn in draw-in groove 6, suture is pushed and by force by gap between card article 2 and the draw-in groove another side 3, enter in the draw-in groove 6, can pull on the moving-wire body, force fluking type latch 4,5 to open certain slit, the line body enters within the closed inside groove 7; Again the end of a thread that turns back is drawn in that the gap internal fixation can use well between the card article 2 of backshank and the draw-in groove another side 3.Draw-in groove 6 oblique interior tooth bar 2 and the fluking type latches 4,5 that are provided with can prevent that all the principal vertical line body shifts out.
This utility model is not restricted to this specific embodiment, it can also be made in the described protection domain of claim 1 and well known to a person skilled in the art all equivalent variations, such as, a pair of latch of described draw-in groove inside also can need not to be provided with, or sets up the 3rd pair of latch again; Described tooth bar shape is arranged at the inboard on one side relative on the draw-in groove 3 with card article; Spacing between described card article and the draw-in groove another side can be set to other sizes; The needle body material adopts other materials; Or the like change, all should regard as and still belong to protection domain of the present utility model.
