AI Technical Summary

Technical Problem

Balloon dilation catheters are prone to puncturing the human body during insertion, requiring highly experienced operators.

Method used

A balloon dilation catheter was designed, comprising an inlet tube, a dilation assembly, and a rubber membrane. Utilizing a core and spring structure, the rubber membrane is inflated and inserted by gas. Combined with a traction line to control gas flow, it avoids direct puncture of the human body.

Benefits of technology

This effectively avoids the catheter puncturing the human body during insertion, reduces the difficulty of operation, and improves safety and controllability.

Abstract

The application discloses a balloon dilatation catheter for interventional therapy, which comprises a leading tube front section, an expansion assembly connected to one end of the leading tube front section, a leading tube rear section connected to the end of the expansion assembly away from the leading tube front section, and a rubber film fixedly connected to the inner wall of the front port of the leading tube front section, and relates to the technical field of dilatation catheters. The balloon dilatation catheter can solve the problem that the leading tube is easily punctured into the human body during the insertion process.
