AI Technical Summary

Technical Problem

Existing microwave ablation probes are difficult to fix during puncture and ablation, leading to positional deviations and complications. Furthermore, existing devices have complex structures, affecting puncture accuracy and increasing the length of the ablation probe.

Method used

A microwave ablation needle fixation bracket was designed, including a hinged left and right bridge arm, a universal ball and a locking mechanism. The ablation needle is fixed by the universal ball and the socket-shaped clamp, and the elastic rubber gasket and locking mechanism ensure the fixation effect, avoiding manual support and reducing radiation exposure.

Benefits of technology

This allows for the stabilization of the ablation probe after puncture, reducing the operator's workload, avoiding positional deviation and radiation exposure, and maintaining the flexibility and accuracy of puncture.

Abstract

The application discloses a microwave ablation needle fixing support, characterized by comprising: hinged left and right bridge arms, a universal ball suitable for being clamped and fixed between the two bridge arms, and a locking mechanism for locking the clamped state of the two bridge arms, wherein the universal ball is provided with a vertical slot, and an elastic rubber gasket for clamping and fixing a microwave ablation needle is arranged in the vertical slot. After the microwave ablation probe completes puncture, the ablation probe has a certain relative position and included angle with the skin plane of a patient. The application can firmly fix the ablation probe on the skin of the patient without increasing the puncture difficulty, increasing the length of the ablation probe, or changing the puncture state of the ablation probe after the puncture is completed, so as to prepare for subsequent ablation operation. After the ablation operation is completed, the gear locking device is opened, and the fixing support can be conveniently removed.
