Endoscopic Suture Needle Device

Abstract

The invention relates to an endoscope suture needle device, which comprises a suture needle, a hard suture needle guide pipe and a suture guide thread, wherein the suture needle is made of nickel-titanium memory alloy, the suture needle front end is formed into the shape suitable for surgical suture, such as the circular needle shape, the suture needle penetrates through the suture needle guide pipe, the suture needle front end can be pulled to form a linear shape to be positioned in the suture needle guide pipe, and can be also pushed out of the suture needle guide pipe and takes the formed shape of circular needle, the suture needle back end is arranged outside a pipe body, far away from a tissue suturing end, of the suture needle guide pipe, a threading hole is formed in the front end of a needle point of the suture needle, the suture guide thread penetrates through the threading hole of the suture needle, the device further comprises a suture lock retaining ring which adopts a side-by-side double-ring structure made of metal of non-nickel-titanium memory alloy. The device is only required to be matched with other forceps holders so as to realize single or repeatedly continuous suture and ligaturing, so that the suture accuracy and quality are improved, and the operation is convenient.

Description

technical field [0001] The invention relates to a clinical endoscopic suturing instrument, in particular to an endoscopic suturing needle device. Background technique [0002] Endoscopy has been promoted in China in recent years, and it is currently a widely used clinical examination and treatment instrument. However, a large number of endoscopic suturing processes require additional openings and additional suturing instruments to perform the operation. If the suture process can be completed only through the operation hole of the endoscope, it will not only greatly facilitate and simplify the operation process, reduce unnecessary incisions and injuries, but also help patients recover; Advanced endoscopic suturing instruments are also studied, but the structures are all complicated and inconvenient to operate. Contents of the invention [0003] In order to achieve the purpose of using an endoscopic suture needle device to pass through the operation hole of the endoscope to...
