Problems solved by technology

[0002] With the popularization of various endoscopic operations in hospitals, how to reliably suture under the endoscope (such as pediatric hernia surgery), reduce tissue damage and complications, shorten operation time, and lower the learning curve is an important research to improve the effect of surgery and improve the quality of surgery. At present, the method of suturing in vitro is still followed under endoscopy. During the suture process, due to the difficulty of suturing under endoscope, it is easy to damage tissues or organs, and even the suture needle cannot be found after suturing, resulting in adverse consequences. Even if the suture is successful , it is inconvenient to take out and put in the suture needle

Embodiment 1

[0029] See Figure 1-2 , a kind of net bag suturing needle that brings into endoscopic operation, comprises needle body 1, the needle head 2 that is arranged on the front end of needle body 1, and the needle hole 3 that is opened in needle head 2, and the outer wall of described needle body 1 is provided with scale 4 And scale value 5, scale 4 comprises long scale 41 and short scale 42, is provided with four short scales 42 between adjacent two long scales 41, and the distance between adjacent two long scales 41 is 0.5cm, adjacent The distance between the two short scales 42 is 0.1 cm, the scale value 5 is set on one side of the long scale 41 , and a scale value 5 is set every two long scales 41 from the front end of the needle body 1 .

[0030] In this embodiment, the length of the needle body 1 is 15 cm, the diameter is 1 mm, the length of the scale 4 is 120 cm; the length of the needle head 2 is 3 mm, and the diameter of the pinhole 3 is 0.6 mm.

[0031] In this embodiment...

Embodiment 2

[0049] The difference between this embodiment and the above-mentioned embodiment 1 is: the length of the needle body 1 is 18cm, the diameter is 1.1mm, the length of the scale 4 is 14cm; the length of the needle head 2 is 4mm, the needle The diameter of hole 3 is 0.8mm.

[0050] The needle body 1 is made of medical stainless steel material, and the medical stainless steel material includes the following chemical elements in weight percentage: C: 0.12%, Si: 0.7%, Mn: 8%, Al: 0.2%, Cr: 15%, Ni: 2%, N: 0.7%, Mo: 2.8%, Cu: 1.1%, Ti: 0.2%, Zr: 0.02%, Re: 0.02%, P≤0.008%, S≤0.008%, and the balance is Fe.

[0051] The preparation method of the needle body 1 comprises the following steps:

[0052] (1) Melting: Nitrogen protection, refining at 1412°C according to the above chemical composition ratio, nitrogen pressure maintained at 0.32MPa, pouring temperature at 1405°C to obtain a vacuum ingot, and then electroslag remelting with inert gas protection to obtain surface quality Smoothe...

Embodiment 3

[0061] The difference between this embodiment and the above-mentioned embodiment 1 is: the length of the needle body 1 is 20cm, the diameter is 1.2mm, the length of the scale 4 is 16cm; the length of the needle head 2 is 4mm, the needle The hole 3 has a diameter of 1 mm.

[0062] The needle body 1 is made of medical stainless steel material, and the medical stainless steel material includes the following chemical elements in weight percentage: C: 0.15%, Si: 0.8%, Mn: 9%, Al: 0.3%, Cr: 16%, Ni: 3%, N: 0.8%, Mo: 3%, Cu: 1.2%, Ti: 0.3%, Zr: 0.03%, Re: 0.03%, P≤0.005%, S≤0.005%, and the balance is Fe.

[0063] The preparation method of the needle body 1 comprises the following steps:

[0064] (1) Melting: nitrogen protection, refining at 1475°C according to the above chemical composition ratio, nitrogen pressure maintained at 0.35MPa, pouring temperature at 1410°C to obtain vacuum ingots, and then electroslag remelting with inert gas protection to obtain surface quality Smoother...

Abstract

The invention relates to the technical field of minimally invasive medical devices, in particular to a take-in type endoscopic surgery net bag suture needle. The take-in type endoscopic surgery net bag suture needle comprises a needle body, a syringe needle arranged at the front end of the needle body and a needle hole formed in the syringe needle, wherein scales and scale values are formed on the outer side wall of the needle body; the scales comprise the long scales and the short scales; four short scales are arranged between every two adjacent long scales; the distance between every two adjacent long scales is 0.5 cm; the distance between every two adjacent short scales is 0.1 cm; the scale values are arranged on one side of the long scales; one scale value is arranged every two long scales from the front end of the needle body. The scales and the scale values are formed on the outer side wall of the needle body, the piercing depth and position can be clear, the structure is simple, the suture needle is economical and practical and can be accurately pushed to the predetermined position due to the scale identifications, and complications such as tissue and organ injury are reduced.
