Abstract

The invention discloses a bracket conveying system with a retraction function. The bracket conveying system comprises a soft head, a developing ring, an inner pipe, a back fixer, a middle pipe, an outer pipe, a connecting piece, a stainless steel push rod, a push handle and a bracket, wherein the soft head, the developing ring, the inner pipe, the back fixer, the middle pipe, the stainless steel push rod and the push handle are connected integrally to form an inner pipe assembly; the connecting piece, the developing ring and the outer pipe are connected integrally to form an outer pipe assembly; the bracket is nested in a cavity between the inner pipe assembly and the outer pipe assembly; a supporting leg at the near end of the bracket is clamped on the back fixer; and after the inner pipe assembly is fixed, the bracket can be pushed and pulled to release and retract by pushing and pulling the outer pipe assembly.

Description

technical field [0001] The present invention relates to the technical field of medical equipment, and is a stent delivery system with a retractable function. During an operation, the stent is delivered to the stenotic segment of the diseased blood vessel through the stent delivery system with the retractable function. The dilating properties widen narrowed blood vessels, thereby restoring blood vessel patency. The stent delivery system has a retractable feature to readjust the stent position during stent release. Background technique [0002] With the improvement of people's living standards and changes in lifestyle, the incidence of peripheral vascular diseases is increasing. If these diseases are not treated in time, they may cause blood vessel blockage, which will seriously endanger human life. [0003] With the progress of the times, at present, minimally invasive interventional surgery is mainly used. This type of method has the characteristics of less trauma to patien...
