AI Technical Summary

Technical Problem

Existing high-frequency surgical equipment relies solely on impedance measurement to distinguish between biological tissues and non-tissue conductive media, leading to ambiguity in identification and making it difficult to achieve safe and effective energy control in complex surgical scenarios.

Method used

An asymmetric biphase diagnostic pulse is used to generate a polarized electric field. The transient residual voltage signal is captured by a signal acquisition module. By combining analog and digital processing, dielectric absorption quantization parameters are calculated to realize a dual safety verification mechanism to control energy output.

Benefits of technology

It improves surgical safety by distinguishing biological tissues from conductive fluids through physical properties, reducing the risk of erroneous energy output, and enhancing the directness and reliability of energy output.

Abstract

本发明属于高频电外科设备及控制的技术领域,具体公开提供的一种高频手术器械与组织智能接触甄别系统,包括:通过施加非对称双相诊断脉冲建立探测电场,并在测量死区内采集瞬态残余电压信号。该信号被分设为数字与模拟两路:数字信号用于计算介电吸收量化参数,据此与阈值比较,分类出有效组织接触或导电液体接触状态;模拟信号则直接生成一个模拟控制电压。在接收到主输出指令时,该模拟控制电压无需任何数字处理,直接以连续、成比例的方式对高频能量输出级进行调制,实现基于实时接触质量的瞬时自适应闭环能量控制,有助于提升手术的安全性与有效性。
