Description

Technical Field

[0001] The utility model relates to a surgical machine, in particular to an internal hemorrhoid suture needle used in anorectal surgery. Background Art

[0002] Chinese Patent 201922023370.8 discloses an anorectal surgical suture needle, comprising a needle handle, a needle tip, a swinging needle, a needle hole, and a handle. The needle handle is arranged between the handle and the needle tip, one end of the needle handle is fixedly connected to the handle, and the other end is fixedly connected to the needle tip. The needle tip is hinged with a swinging needle at one end close to the needle handle, and the swinging needle flips toward one end of the needle tip. The needle tip and the swinging needle are arranged to open and close. The combined shape of the needle tip and the swinging needle is a parallelogram. The needle tip and the swinging needle have a needle hole inside. The needle hole can be opened or closed by opening or closing the swinging needle to prevent the suture from falling off and to avoid damage to the tissue during withdrawal. It is suitable for upper and lower suturing in the rectal cavity, saving time and effort. It has a crochet needle head and a suitable needle handle hardness and curvature. The patent structure is relatively complex and is not very convenient for suturing internal hemorrhoid surgery, and further improvement is needed. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned defects of the prior art and provide an internal hemorrhoid suture needle.

[0004] To achieve the above-mentioned purpose, the technical solution provided by the utility model is as follows: constructing an internal hemorrhoid suture needle, including an operating handle and a needle body, the needle body is U-shaped, one end of the needle body is a long part, and the other end is a short part, the rear end of the long part is fixedly connected to the middle of the front part of the operating handle, the front end of the short part is pointed, and a threading hole is opened at the front of the short part.

[0005] Furthermore, the distance between the threading hole and the front end of the short portion of the needle body is 3 to 6 mm.

[0006] Furthermore, the junction between the long part and the short part of the needle body is in an arc shape.

[0007] Furthermore, the turning point between the long part and the short part of the needle body is a rounded chamfer.

[0008] Furthermore, the diameter of the needle body is 1.5-2.0 mm.

[0009] Furthermore, the diameter of the threading hole is 1.0-1.2 mm.

[0010] Furthermore, an anti-slip strip is provided on the operating handle.

[0011] The benefit of the utility model is that it replaces the ordinary needle holder for clamping and suturing, and solves the problem of difficult operation inside the anus. The internal hemorrhoid suturing needle is carefully designed according to the characteristics of the tubular structure of the anus, and can be operated up and down inside the anus for suturing. It is easy to operate, reduces suturing time, shortens the operation cycle, and is worthy of promotion in the industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and preferred embodiments.

[0016] See Figure 1 The preferred embodiment shown is an internal hemorrhoid suture needle, comprising an operating handle 1 and a needle body 2. The needle body 2 is U-shaped, with one end of the needle body 2 being a long portion 21 and the other end being a short portion 23. The rear end portion 211 of the long portion 21 is fixedly connected to the middle of the front portion 11 of the operating handle 1, the front end portion 231 of the short portion 23 is pointed, and a threading hole 235 is provided at the front portion of the short portion 23.

[0017] The distance between the threading hole 225 and the front end of the needle body short portion 23 is 3-6 mm.

[0018] The junction 25 between the long portion 21 and the short portion 23 of the needle body 2 is in an arc shape (not shown in the figure).

[0019] The junction 25 between the long portion 21 and the short portion 23 of the needle body 2 is a rounded chamfer.

[0020] The diameter of the needle body 2 is 1.5 mm.

[0021] The diameter of the threading hole 235 is 1.0 mm.

[0022] The operating handle 1 is provided with an anti-slip strip 13 .

[0023] See Figure 2 As shown, the suture thread 3 is inserted into the threading hole 235 of the internal hemorrhoid suture needle, and then the surgical site is sutured up and down after the anus 5 internal hemorrhoid surgery. It is easy to operate, reduces the suturing time, shortens the operation cycle, and is worthy of promotion in the industry.

[0024] The above description is only the principle and preferred embodiment of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the principle of the present invention, and they should also be considered to fall within the scope of protection of the present invention.
