Embodiment

[0016] Example: as figure 1 , 2 As shown, the self-made auxiliary device with film bracket is composed of film fixed bearing base 1, bracket fixed auxiliary roller 2 and bracket 3. A film fixing panel 11 is provided in the middle of the film fixing base 1 for placing the film 4 . A mounting groove 12 is provided at the left and right ends of the film fixing bearing base 1 respectively, for mounting the bracket and fixing the auxiliary roller 2 . A bracket 3 is arranged between the left and right brackets to fix the auxiliary rollers 2 . The support 3 is arranged on the upper end of the film 4, and is clamped and fixed by the support fixed auxiliary rollers 2 at both ends. The support fixed auxiliary roller 2 and the supporting fixture 12 are connected by bearings, and the support fixed auxiliary roller 2 is rotatable. The bracket fixes the auxiliary roller 2 to rotate, and simultaneously drives the bracket 3 to rotate.

Abstract

The present invention relates to medical devices and particularly to a self-made membrane-contained stent auxiliary device. The self-made membrane-contained stent auxiliary device comprises a thin membrane fixing bearing base seat, a thin-membrane fixing panel is arranged in a middle part of the thin membrane fixing bearing base seat, a supporting clamp tool is arranged at each of a left end and aright end of the thin membrane fixing bearing base seat, each supporting clamp tool is provided with a stent fixing auxiliary rolling device, a stent is arranged between the left stent fixing auxiliary rolling device and the right stent fixing auxiliary rolling device, positioned at an upper end of the thin-membrane fixing panel and fixed by the stent fixing auxiliary rolling devices at two ends,and the stent and the stent fixing auxiliary rolling devices are connected on a central shaft in series; and the stent fixing auxiliary rolling devices are connected with the supporting clamp tools in a bearing type, and the stent fixing auxiliary rolling devices can rotate. The self-made membrane-contained stent auxiliary device improves a success rate of a self-made membrane-contained stent, isused for treating other arteries except coronary arteries, vein vessel perforation, arteriovenous fistula and aneurysm, increases timeliness of a rescue treatment, and improves a success rate of rescue of perforation and rupture of coronary blood vessels in coronary intervention operations.

Description

technical field [0001] The invention relates to a medical device, in particular to a self-made auxiliary device for a stent with membrane. Background technique [0002] Vascular stents are mainly divided into coronary artery stents, cerebrovascular stents, renal artery stents, aortic stents, etc. Coronary artery stents, also known as cardiac stents, are commonly used medical devices in cardiac interventional operations. They have the function of dredging arteries. It first appeared in the 1980s and experienced the development of metal stents, coated stents, and soluble stents. Nowadays, stent-graft is the key treatment method for acute coronary perforation and coronary artery rupture. It can successfully seal most perforations in the proximal and middle segments of coronary arteries, thereby avoiding surgery and greatly improving the prognosis of coronary artery perforation. , An important means of treatment of aneurysms in coronary artery bypass vein vascular grafts. The...
