Detailed Description

Fig. 1 to 3 are preferred embodiments of the present invention, and the present invention will be further explained with reference to fig. 1 to 3.

Example 1:

as shown in fig. 1, an operation needle (hereinafter, referred to as an operation needle) applied to a laparoscopic operation includes a needle body 2 bent in an arc shape, one end of the needle body 2 is a needle point 1, the other end is a needle tail 4, and a needle hole 3 for passing a suture thread 6 (see fig. 4) is formed at the needle tail 4. In the present embodiment, the needle body 2 and the needle tail 4 are integrally formed.

With reference to fig. 2, the cross section of the needle tail 4 in the surgical suture needle is an isosceles triangle, the vertex angle of the isosceles triangle is preferably an obtuse angle, and the bisector of the vertex angle passes through the needle tip 1. The base angles of the two sides of the needle tail 4 isosceles triangle are processed by adopting the fillet, so that the cutting damage to tissues caused by the base angles in the sewing process is effectively avoided.

The specific operation process is as follows:

when the operation suture needle is used for performing postoperative suture, firstly, a suture line 6 is connected through the needle hole 3, and then a doctor holds the needle holder 5 to perform suture operation on a wound.

In the conventional postoperative suturing process, the needle holder 5 is generally clamped at the needle tail 4 when clamping a surgical suture needle, because the cross section of the needle tail 4 of the surgical suture needle adopts an isosceles triangle with an obtuse angle at the vertex angle, when the needle holder 5 clamps the base angle of the isosceles triangle, the needle body 2 can rotate due to the clamping position until the vertex angle contacts with one clamping surface of the needle holder 5 because the length of the base edge is longer and the base angle adopts the fillet treatment, and the base edge is attached to the other clamping surface of the needle holder 5 as shown in fig. 3, and at the moment, the vertex angle of the isosceles triangle is embedded into a sawtooth groove (not shown in the figure) of the clamping surface to realize fixation, and at the moment, the needle body 2 can not rotate again, so that a doctor can carry out suturing operation.

Example 2:

this example differs from example 1 in that: as shown in fig. 4, in the present embodiment, the needle hole 3 at the needle tail 4 is omitted, and the sewing thread 6 is fixed at the needle tail 4, so that the step of connecting the sewing thread 6 with the needle hole 3 is omitted when performing the postoperative sewing.
