Embodiment Construction

[0017] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] see image 3 , Figure 4 As shown, the threaded suture needle of the present invention is basically the same in structure as the prior art, and is also composed of a medical suture needle and a suture 3. The medical suture needle includes a needle body 1 and a needle point 2 at the front end of the needle body 1, Moreover, the longitudinal section of the needle point 2 is triangular, and the surface of the suture 3 is also provided with a coating. The difference is that the longitudinal section of the needle tip 2 of the present invention is improved from the existing isosceles triangle with vertex angles of 75° to equilateral triangles with vertex angles of 60°. In addition, the three outer surfaces of the needle point 2 are all sand surfaces, that is to say, the needle point 2 has three cutting edges, which is a thr...

Abstract

The invention discloses a suture needle with a suture line and a suture line coating. The suture needle consists of a suture needle and a suture line, wherein the suture needle comprises a needle body and a needle tip at the front end of the needle body; the coating layer is arranged on the surface of the suture line; and the longitudinal section of the needle tip is an equilateral triangle with each angle being 60 degrees. The strength of the needle tip is effectively improved through the needle tip with the shape, puncturing is facilitated, and the trauma to the surface is relatively low, so that the suture needle enjoys exceptional advantage and is worth of being applied and popularized. The invention also discloses the suture needle with the suture line, and a mixture of hydroxyacetic acid-hydracrylic acid copolymer and calcium stearate is adopted. The coating is higher in strength, stability and surface smoothness and more facilitates piercing in tissues of a human body, the resistance and the tearing degree of a wound surface are reduced, the suture line is easier to knot and not easy to disperse after a suture surgery is finished, and the firmness of knotting is further improved.

Description

technical field [0001] The present invention relates to surgical instruments, more specifically, to a threaded suture needle and its suture coating. Background technique [0002] Suture needle with thread is composed of two parts: medical suture needle and suture thread. According to the shape of the needle body, medical suture needles can generally be divided into two types: angle needles and round needles. Compared with round needles, angled needles have greater puncture force and correspondingly greater damage. However, in the use of angle needle type suture needles for surgery, the doctor pays more attention to the feel. If the resistance suffered during puncture is small, the clinical manifestation is that it is easier to puncture skin tissue. [0003] At present, the traditional angle needle type suture needle such as figure 1 , figure 2 As shown, including the needle body 1 and the needle point 2 at the front end of the needle body 1, the longitudinal section of ...
