AI Technical Summary
Technical Problem
The electrodes in existing shock wave ducts have a poor distribution structure on the balloon, resulting in poor electrical contact and lack of ductility, and they are subjected to large stresses during balloon deformation.
Method used
The electrodes are designed with a spring-like helical structure, and a first support mechanism is set between the electrodes to provide axial support force and a second support mechanism to provide radial support force. The support mechanism reduces the stress on the electrodes during the deformation of the balloon.
Benefits of technology
It achieves good electrical contact and excellent electrode ductility, reduces the stress on the electrodes during balloon deformation, and improves the stability and safety of catheter use.

Abstract
This invention relates to the field of shock waveguide technology and discloses a spring electrode shock waveguide, comprising a slender carrier and a balloon. The space formed between the balloon and the carrier is an annular channel for fluid to enter and achieve inflation. First, the electrode in the guide tube is designed as a spring-type spiral structure and wound around the surface of the carrier, which can provide good electrical contact and make the electrode have excellent ductility, solving the problem of large stress on the electrode during the deformation of the balloon under fluid compression. Through the design of a first support mechanism and a second support mechanism, the first support mechanism is connected between two adjacent outer walls of the electrode, providing axial support force for the electrode, and the second support mechanism is connected between the inner wall of the balloon and the outer wall of the electrode, providing radial support force for the electrode. This reduces the pressure on the electrode when the internal pressure of the balloon increases and the balloon expands, further solving the stress problem of the electrode during the deformation of the balloon.
