Abstract

The invention relates to a threading-free medical suture needle, which is an instrument for suture in a surgical operation process. The threading-free medical suture needle comprises a bent needle body (1), and is characterized in that one end of the bent needle body (1) is sharp, a groove (6) is formed at the other end of the bent needle body (1), an opening is arranged at the upper end of the U-shaped groove (6), two surfaces which inwards extend are respectively arranged at the left end and the right end of the U-shaped groove (6) and are mutually parallel, and a gap is formed between the two mutually parallel surfaces (5), and is smaller than or equal to a threading diameter. The threading-free medical suture needle is fast in operation, and can greatly saves threading time, a doctor using the suture needle does not need good vision and hand and eye coordination ability, so that the speed of surgery is increased, and sufferings of patients is relieved.

Description

Threading-free medical suture needle

Technical field

The invention belongs to medical equipment, particularly a kind of threading-free medical suture needle, is the apparatus for sewing up in surgical procedures process.

Background technology

Sewing needle is one of requisite apparatus in surgical procedures process, the pin hole of domestic general sewing needle is rectangle pin hole at present, when use, need patient or nurse stitching thread through pin hole, the returning line that turns back, returning line is stuck in after fixing on needle holder and could uses.Have the following disadvantages: 1. the pin hole of sewing needle is very little, often occur that thick suture wears to enter little stitching pin hole; 2. when stitching thread pronged, be difficult to penetrate pin hole; 3. require patient or nurse to have good vision and hand-eye coordination ability just can thread a needle accurately, rapidly.Common sewing needle because of the time of threading a needle long, waste time and energy, affect operation progress.

Summary of the invention

In order to overcome above-mentioned deficiency, the better operation efficiency that improves, the object of the invention is a kind of quick, threading-free medical suture needle of invention.

The object of the present invention is achieved like this, a kind of threading-free medical suture needle, comprise a bending needle body, it is characterized in that: bending needle body one end point, the other end forms a U-lag, U-lag upper end open, there are respectively two faces that extend internally at two ends, left and right, two faces are parallel mutual, and gapped between two mutual faces, gap is less than or equal to threading wire diameter.

The bottom surface of described two mutual faces and U-lag forms elliptical line hole.

Described two mutual faces outsides form downwards with angle polygon leg.

Two described mutual face inner sides form the upwards gear line limit with radian.

Described suture needle arc diameter is 14mm, and needle body length is 22 ± 1mm, and needle point is 0.3mm, and backshank is 1.2mm.

Advantage of the present invention is: bending needle body one end point, the other end forms a U-lag, U-lag upper end open, there are respectively two faces that extend internally at two ends, left and right, two faces are parallel mutual, gapped between two mutual faces, gap is less than or equal to threading wire diameter, line-entering hole is entered in the mutual face gap that suture can be opened by backshank, cannot deviate from backshank in former road again, greatly save the time of threading a needle, and not need good vision and hand-eye coordination ability, thereby the speed of having accelerated operation, has alleviated patient's misery.

Accompanying drawing explanation

Below in conjunction with embodiment accompanying drawing, the invention will be further described (sewing up round needle as example take clinical 1/2 conventional arc):

Fig. 1 is embodiment of the present invention structural representation front view;

Fig. 2 is that Fig. 1 backshank amplifies plan view;

Fig. 3 is Fig. 1 backshank amplification plan view.

In figure, 1, needle body; 2, backshank; 3, the stitching thread hole of threading a needle; 4, elliptical line hole; 5, two mutual faces; 6, U-lag; 7, polygon leg; 8, gear line limit; 9, gap.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of threading-free medical suture needle, comprises a bending needle body 1, bending needle body 1 one end point, and the other end is the stitching thread hole 2 of threading a needle.

As shown in Figure 2 and Figure 3, Fig. 2 is that backshank 2 amplifies plan view; Fig. 3 is backshank 2 amplification plan views.The stitching thread hole 3 of threading a needle is to be made up of two mutual faces 5 at backshank place, and two mutual faces 5 are in backshank 2.Stitching thread is threaded a needle hole 3 at a U-lag 6 of backshank place formation, U-lag 6 upper end open, and there are respectively two faces that extend internally at two ends, left and right, and two faces are parallel mutual, and two mutual faces 5 form elliptical line hole 4 with the bottom surface of U-lag 6.Gapped 9 between two mutual faces 5, gap 9 is less than or equal to threading wire diameter.

Two mutual face 5 upsides form downwards with angle 7, two mutual face 5 inner sides of polygon leg form the upwards gear line limits 8 with radian.Gapped 9 between two mutual faces 5, gap 9 is less than or equal to threading wire diameter.When threading, line slips into elliptical line hole 4 from gap 9 lines between two mutual faces 5, while slipping into due to line, receive certain pulling force, wire diameter is attenuated, be easy to slip in elliptical line hole 4 by any one polygon leg 7, line enters behind elliptical line hole 4, and lower end and both sides are in natural enclosing ellipse, upper end keeps off line limit 8 by arc again and stops, line is not easy to skid off.

Suture needle arc diameter is 14mm, and needle body length is 22 ± 1mm, and needle point is 0.3mm, and backshank is 1.2mm.

Claims

1. threading-free medical suture needle, comprise a bending needle body (1), bending needle body (1) one end point, it is characterized in that: the other end of bending needle body (1) forms a U-lag (6), U-lag (6) upper end open, there is respectively a face extending internally at two ends, left and right, two mutual faces of two the parallel mutual formation of face, two mutual faces (5) are staggered and be positioned at Different Plane, and between two mutual faces (5) gapped (9), gap (9) are less than or equal to threading wire diameter; Described two mutual faces (5) form elliptical line hole (4) with the bottom surface of U-lag (6); Described two mutual faces (5) outside forms the polygon leg with angle (7) downwards; Described two mutual faces (5) inner side forms the upwards gear line limit (8) with radian.
