Abstract

The invention provides a stent restraining system. The stent restraining system comprises a release assembly and a restraining assembly, wherein the release assembly comprises a release sheath and a conveying device; the restraining assembly comprises a plurality of restraining straps and restraining wires; the restraining straps are arranged in the release sheath, are used for restraining a stentand can be released from a compressed state, the restraining straps are divided into at least two groups, the number of each group of restraining straps is one or more, and the circumferences of therestraining straps in different groups are different when the restraining straps are in the compressed state; and the front end of each restraining wire penetrates into the release sheath and is connected with the restraining straps, the rear end of each restraining wire is connected to the conveying device, and the restraining wire is configured to control the restraining straps to be released. By means of the design, the multi-stage restraining release function that the stent is completely compressed, partially released and completely released can be achieved, so that the expansion process of the stent is fully utilized, implantation of the stent is facilitated, a safer and effective implantation effect is provided, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a stent restraint system. Background technique [0002] For lesions caused by stenosis or tumor-like expansion of human lumen, stents can be placed in the lumen through interventional therapy to eliminate stenosis or isolate tumor-like expansion. The restraint system currently used to place the stent in the lumen realizes its restraint release function by controlling the two states of complete compression and complete release of the stent. For stents with relatively complex structures, such as stents with branches, it is necessary to adjust or change the diameter of part of the stent structure during the release process to achieve a satisfactory implantation effect. However, the fully compressed and fully released restraint release methods adopted by the existing restraint systems cannot meet the above requirements. SUMMARY OF THE INVENTION [0003] A main objective o...
