Multi-sensor deep hot probe

Abstract

The invention relates to a multi-sensor deep hot probe. By adding multiple sensors including pressure sensors, temperature sensors, cerebral oxygen saturation sensors and the like on probe contacts and a medical catheter, multi-sensor monitoring can be realized during implantation and after implantation. Through the probe contacts arranged linearly in the direction of the medical catheter and arranged in a circumferential direction, after a lesion position is discovered, directional controllable-range thermal coagulation can be performed on the lesion position; the lead impedance of the probeis low; and the thermal coagulation effect is good.

Description

technical field [0001] The invention discloses a multi-sensing deep thermocoagulation electrode. By adding a variety of sensors at the electrode site, the process of implanting the electrode can be monitored, and signals such as intracranial pressure, temperature, and cerebral oxygen saturation can be collected after implantation. After the lesion is found, thermal coagulation can be performed on the lesion in a directional direction and within a controllable range. Background technique [0002] For special epilepsy cases such as intractable epilepsy, in addition to needing to implant electrodes to locate the lesion, it is also necessary to implement thermocoagulation treatment on the lesion. Usually, it is necessary to precisely control the temperature to achieve a small thermal coagulation range, and try to avoid functional damage. area or good tissue causing damage and impact. [0003] Commercially available deep thermocoagulation electrodes are usually implanted by mini...

AI Technical Summary

Problems solved by technology

[0005] After implantation, when thermal coagulation treatment is performed on the lesion area, commercially available electrode products usually have high self-impedance and high self-heating of the electrode conductor, which affects the thermal coagulation effect to a certain extent, and may easily cause poor consistency in the thermal coagulation range of the product.

At the same time, since most products use ring electrodes, the thermal coagulation range is the circumferential direction of the entire ring electrode, and thermal coagulation treatment in the circumferential direction cannot be implemented.
