AI Technical Summary

Technical Problem

Existing thrombus aspiration catheters can cause vascular damage due to the concentrated suction force during initiation, resulting in a "wall-biting" phenomenon that increases the risk of surgical complications.

Method used

A pressure relief hole and a sealing component are set at the distal end of the catheter body. The pressure relief hole disperses the instantaneous negative pressure, and the sealing component dynamically controls the pressure relief state to ensure the stability of the suction force.

Benefits of technology

It effectively reduces the adhesion of the distal end of the catheter to the blood vessel wall, reduces intimal tearing and perforation, and improves surgical safety and aspiration efficiency.

Abstract

The invention provides a thrombus aspiration catheter, and belongs to the technical field of intervention equipment. The catheter comprises a catheter body, the near end of the catheter body is connected with suction equipment, the far end of the catheter body is provided with a pressure relief hole used for reducing the instantaneous suction force of the catheter body, and the far end of the catheter body is further provided with a blocking component used for blocking the pressure relief hole so as to control the pressure relief state of the pressure relief hole and guarantee the stability of the suction force of the catheter body. The thrombus aspiration catheter is mainly used for solving the technical problem that when a traditional thrombus aspiration catheter is started, wall biting is easily caused by instantaneous aspiration force concentration, and blood vessel injury is caused.
