Full-degradable metal-based vascular tissue closing clamp for endoscope

Abstract

The invention discloses a fully-degradable metal-based vascular tissue closing clamp for an endoscope. The closing clamp comprises an upper chuck, wherein positioning teeth are installed outside the upper chuck, the bottom end of the upper chuck is connected with a lower chuck, tooth alignment grooves are formed in the lower chuck, and a retention mechanism is installed on the outer side of the lower chuck. In the full-degradable metal-based vascular tissue closing clamp for the endoscope, under the action of the retention mechanism, an existing full-degradable metal-based vascular tissue closing clamp for the endoscope is fixed through metal deformation, but under the condition that polyp is thick, the phenomenon that the clamping effect is poor is likely to be caused, and when the closing clamp is used for clamping, an alignment block is connected to an alignment groove in a fixing block; when the alignment block moves to a certain position, a movable block in the alignment block isreset through a reset spring, and the movable block is clamped in a groove in the fixing block, so that the top end of the closing clamp is effectively positioned, and the phenomenon that the closingclamp is loosened is prevented.

Description

technical field [0001] The invention belongs to the field of laparoscopic surgery, and in particular relates to a fully degradable metal-based vascular tissue closure clip for laparoscopic surgery. Background technique [0002] Laparoscopic surgery is a newly developed minimally invasive method and an inevitable trend in the development of future surgical methods. With the rapid development of industrial manufacturing technology, the integration of related disciplines has laid a solid foundation for the development of new technologies and methods. With the increasingly skilled operation of doctors, many open surgeries in the past have been replaced by endovascular surgeries, greatly increasing the chances of surgical options. [0003] In the existing laparoscopic surgery on vascular tissue, auxiliary tools are needed to operate, so fully degradable metal-based vascular tissue closure clips are needed for assistance, which can close the vascular tissue during use, but it will...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the existing laparoscopic surgery on vascular tissue, auxiliary tools are needed to operate, so a fully degradable metal-based vascular tissue closure clip is needed to assist, which can close the vascular tissue during use, but it will also produce The closure is not firm, and its size cannot be adjusted during use
