Lock catch type loop ligature tightening ring and application thereof

Abstract

The invention relates to a lock catch type loop ligature tightening ring. The lock catch type loop ligature tightening ring comprises a tightening belt and a lock catch; the tightening belt comprisesa binding section located in the middle and clamping sections located at the two ends of the binding section; the lock catch comprises a shell; a fastening hole penetrating through the shell is formedin the shell; the clamping sections of the tightening belt are oppositely bent; and the two clamping sections which are bent oppositely penetrate through the fastening hole from the inserting end ofthe fastening hole and slide in one direction with the fastening hole, and after the clamping sections at the two ends of the fastening belt penetrate through the fastening hole, the binding section forms a binding ring. The lock catch type loop ligature tightening ring has the advantages that the tightening ring is convenient to operate, and meanwhile, the neck of a cyst including a leakage opening is directly ligated and fastened through the irreversible lock catch, and it is guaranteed that cyst fluid does not permeate into the cyst any more.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a lock type ligation constriction ring and its application. Background technique [0002] With the in-depth understanding of sacral canal cysts, most scholars are in favor of simple clinical classification of sacral canal cysts: nerve root-containing and nerve-root-free. This is the premise of standard microsurgical treatment of sacral cysts, and the corresponding surgical methods for the two types of sacral cysts are root cuff reconstruction and capsule neck suture. If it is determined that there is no nerve root in the sacral canal cyst, it can be considered to directly block the source of cyst fluid by ligation of the cyst neck, that is, the leak of the cyst, so as to effectively treat the sacral canal cyst without nerve roots. [0003] At present, in clinical operations, the methods used to ligate the cystic neck are inseparable from surgical sutures (silk threads), ...

Problems solved by technology

Both require the surgeon to have skilled microneurosurgery techniques, which in itself restricts the generalization and application of the surgical method, especially in grassroots hospitals such as counties and cities
