AI Technical Summary

Technical Problem

Existing pulse ablation clamping devices suffer from insufficient surgical flexibility due to the constant relative position of the handle and the fixed clamp, making it difficult to adapt to the tissue orientation of different sites, which may lead to incomplete ablation or tissue damage.

Method used

The device employs a malleable support tube and a flexible transmission assembly. The support tube is capable of plastic deformation, and the first and second ablation clamps can move flexibly and rotate at multiple angles. Combined with the flexible transmission assembly and drive assembly, it achieves close attachment of the ablation electrode and efficient energy transfer.

Benefits of technology

It improves the flexibility and precision of surgery, avoids tissue damage, reduces the risk of infection, reduces vibration and noise, and lowers maintenance costs.

Abstract

This application relates to the field of medical device technology, and in particular to a pulse ablation clamping device, including a handle, a support tube, a first ablation clamp, a second ablation clamp, a flexible transmission assembly, and a drive assembly. One end of the support tube is fixedly mounted on the handle, and its interior communicates with the interior of the handle. The first ablation clamp is fixedly mounted on the end of the support tube away from the handle. The second ablation clamp is movable toward or away from the first ablation clamp on the end of the support tube away from the handle. Compared to existing pulse ablation clamping devices, the support tube can undergo plastic deformation, allowing the first and second ablation clamps to move synchronously and rotate synchronously at multiple angles more flexibly, adapting to the tissue orientation of different sites and improving surgical flexibility. The drive assembly can drive the second ablation clamp toward the first ablation clamp via the flexible transmission assembly. Compared to rigid transmission methods, it can transmit power in a non-linear transmission path.
