AI Technical Summary
Technical Problem
Current intracardiac ultrasound catheters have complex structures that make it difficult to operate and affect the success rate of cardiac procedures due to their cumbersome bending adjustment mechanisms.
Method used
An intracardiac ultrasound catheter with a simple structure featuring a catheter body and a control handle, equipped with wire pulling cavities and a rotating mechanism that allows for the manipulation of pull wires to achieve flexible bending angles by tensioning and relaxing the wires, enabling stepless adjustment.
Benefits of technology
The catheter provides easy operation and precise control over bending angles, enhancing the success rate of cardiac procedures by allowing for seamless adjustment of the ultrasound probe's spatial position and imaging angle.

Abstract
The intracardiac ultrasound catheter with the bend adjusting function comprises a catheter body and a control handle connected to the rear end of the catheter body, a plurality of stay wire cavities are formed in the catheter body, and stay wires capable of freely moving in the stay wire cavities are distributed in the stay wire cavities; one end of each stay wire is fixed at the front end of the catheter body, and the stay wires spaced by 180 degrees form a pair; the other end of each stay wire is fixed on the control handle; the control handle comprises a fixing mechanism and a rotating mechanism; the rotating mechanism is movably connected to the fixing mechanism and can rotate around the self axis longitudinally arranged along the control handle; the tail ends of the stay wires are fixed to the corresponding rotating mechanisms, and the rotating mechanisms drive the corresponding stay wires to longitudinally move along the control handle when rotating so as to control tensioning and loosening of the corresponding stay wires to control deformation of the front end of the catheter body, and bending shapes of different angles are generated. The intracardiac ultrasound catheter can be bent in a stepless mode, and is simple in structure and convenient to operate.
