Problems solved by technology

[0004] However, with the reduction of the piercing resistance, it is easy to pierce the surgical gloves worn by the surgeons including doctors and nurses during the operation, and there is a problem that the risk of injury to the surgeon is likely to arise.
In particular, when a surgical glove is damaged by a medical suture needle attached to a patient's body fluid, there is a problem that the operator wearing the surgical glove may be infected.

Embodiment 1

[0028] Embodiments of the suture needle of the present invention will be described with reference to the drawings. figure 1 It is a figure explaining the structure of the suture needle of this Example.

[0029] Such as figure 1 The shown suture needle A forms a needle point 1 at the front end, forms a tapered portion 2 continuously with the needle point 1, forms a needle body portion 3 continuously with the tapered portion 2, and forms a needle for installing a The root end 4 of the locking hole 5 of the suture shown in the figure. The cross-sectional shapes of the tapered portion 2 and the needle body portion 3 of the suture needle A are circular.

[0030] In particular, the needle tip 1 is formed in a spherical shape, and the diameter of the ball constituting the needle tip 1 is set within a range of 0.25 mm to 0.34 mm. In addition, the taper angle of the taper portion 2 is set within a range of 8.5° to 9.4°. Furthermore, by having the spherical needle tip 1 and the tape...

Abstract

Provided is a medical suturing needle or a round needle having a circular section, which is balanced between the magnitude of an insertion resistance to living tissues and the difficulty in damaging gloves, thereby to improve the safety. The medical suturing needle (A) comprises a ball-shaped needle tip (1), a tapered portion (2) continuing to the needle tip (1), and a trunk portion (3) continuing to the tapered portion (2). The ball of the needle tip (1) has a diameter of 0.25 mm to 0.34 mm, and the tapered portion (2) has a tapering angle of 8.5 degrees to 9.4 degrees.

Description

technical field [0001] The present invention relates to a kind of suturing needle for medical treatment, relate in particular to a kind of needle that does not pierce the surgical glove And the dangerous medical suture needle that injures the operator. Background technique [0002] Among medical suture needles used for suturing living tissue, there are needles whose cross-sectional shape from the needle point to the needle body is circular, and the cross-sectional shape of the needle body is circular, triangular, square, flat, etc. Needles of needles, angular needles in which cutting edges are formed on a plurality of ridges in a polygon including triangles. The round needle also includes the blunt needle with a blunt front end, which penetrates the tissue of the body and passes through it in a way of expanding the tissue, and the angled needle passes through while cutting the tissue. Therefore, the most suitable medical suture needle is selected and used according to the ...
