Adjustable multifunctional cardiovascular stent

Abstract

The invention discloses an adjustable multifunctional cardiovascular stent, and belongs to the technical field of cardiovascular treatment equipment. The adjustable multifunctional cardiovascular stent comprises a front cover ring and a rear cover ring; the opposite sides of the front cover ring and the rear cover ring are jointly and fixedly connected with a fixing column; the side, close to the front cover ring, of the rear cover ring is rotatably connected with a first rotating column, a second rotating column and a third rotating column through bearings; a shaft arm of the first rotating column is fixedly connected with a first curved bar and a first eccentric wheel; and a shaft arm of the second rotating column is fixedly connected with a second curved bar and a second eccentric wheel. According to the intravascular stent, through mutual cooperation of the above structures, medical staff can conveniently take and place the device in a blood vessel, the operation difficulty of the medical staff is greatly reduced, the device can be automatically unfolded or folded in the blood vessel; and damage to the blood vessel and infection of a patient caused by a process in which an intravascular stent is installed and taken out can be avoided; and the problems that a traditional intravascular stent is inconvenient to disassemble and assemble, single in function and prone to injuring blood vessels are solved.

Description

technical field [0001] The invention relates to the technical field of cardiovascular treatment equipment, in particular to an adjustable multifunctional bracket for cardiovascular. Background technique [0002] Vascular stent refers to the placement of internal stents in the diseased segment on the basis of lumen balloon expansion to support the stenotic and occluded segment of the vessel, reduce elastic recoil and reshaping of the vessel, and maintain smooth blood flow in the lumen. Some internal stents also have the function of preventing restenosis, mainly divided into coronary stents, cerebrovascular stents, renal artery stents, aortic stents, etc. Traditional vascular stents are usually directly inserted into blood vessels after being deployed outside the blood vessels. When the stent is replaced and taken out, the vascular stent in the deployed state is also directly pulled out, which not only easily leads to damage to the inner wall of the blood vessel, but also caus...

Problems solved by technology

[0003] The purpose of the present invention is to provide an adjustable multifunctional stent for cardiovascular, which is convenient for medical personnel to take and place the device in the blood vessel, greatly reduces the difficulty of operation for the medical personnel, and the device can be automatically deployed inside the blood vessel or Shrinkage, avoiding damage to blood vessels when the vascular stent is installed and taken out, leading to patient infection, and solving the problems of inconvenient disassembly, single function and easy damage to blood vessels of traditional vascular stents
