AI Technical Summary

Technical Problem

Existing stents are inefficient when faced with large amounts of thrombus accumulation, which can easily lead to thrombus escape, increasing the risk of pulmonary embolism complications. Furthermore, stent removal is inconvenient and prolongs the operation time.

Method used

Design a thrombectomy device comprising a control handle, a catheter assembly, and a thrombectomy stent. Utilize an aspiration tube and inner and outer tubes to release and retrieve the thrombectomy stent. Aspirate the thrombus through the aspiration tube, and combine with a cutting element and a collection net to improve thrombectomy efficiency.

Benefits of technology

It improved thrombectomy efficiency, reduced pulmonary embolism complications caused by thrombus escape, shortened operation time, and enhanced thrombus clearance efficiency.

Abstract

The application relates to a thrombus taking device which comprises a control handle, a catheter assembly and a thrombus taking support, the catheter assembly comprises an inner tube, a suction tube and an outer tube, the proximal end of the suction tube is fixedly connected with the distal end of the control handle, the suction tube has a central lumen and a suction tube cavity, the central lumen extends from the proximal end of the suction tube to the distal end of the suction tube, the distal end of the suction tube cavity is provided with a suction port, and the proximal end of the suction tube cavity is used for being connected with a negative pressure source, the inner tube is movably arranged in the central lumen in an axial direction, and the distal end of the inner tube extends out of the distal end of the suction tube, the outer tube is movably arranged outside the suction tube in an axial direction, the thrombus taking support can be accommodated in the outer tube when the outer tube moves towards the distal end relative to the suction tube, the thrombus taking support can be moved out of the distal end of the outer tube when the outer tube moves towards the proximal end relative to the suction tube, and the suction port is exposed to the distal end of the outer tube. The thrombus taking device of the application realizes cooperation of suction of blood clots and mechanical thrombus taking of the thrombus taking support, so that the thrombus taking efficiency is improved.
