AI Technical Summary

Technical Problem

The existing ultrasonic knife technology fails to stop the excitation in time after the tissue or blood vessel is disconnected, causing the blade to come into contact with the tissue pad, accelerate wear and temperature rise, and affect the surgical effect.

Method used

By obtaining the impedance values ​​of tissues and organs at multiple time points, calculating the rate of change of impedance values, determining whether the tissues and organs are completed, and prompting to be cut off when the judgment is completed, dynamically adjusting the energy output to avoid overheating of the knife head.

Benefits of technology

Effectively judge the breaking status of tissues and organs, avoid wear and overheating of the knife head, extend the service life of the ultrasonic knife, and improve the reliability and efficiency of the surgery.

Abstract

The invention discloses a control method and device for tissue and organ separation prompt and a computer readable medium, and the control method for tissue and organ separation prompt comprises the steps: obtaining impedance values of tissue and organs at a plurality of time points in the working process of an ultrasonic knife; calculating the change rate of the impedance value; according to the change rate of the impedance value, judging whether the tissue organ is disconnected or not; and prompting that the tissue and organ disjunction is finished. Whether the tissue organ is disconnected or not is judged by calculating the change of the impedance slope of the tissue organ, different tissues can be judged, and the application range is wide. The energy output is dynamically adjusted based on the change of the impedance slope of tissues and organs, so that the temperature of the tool bit is not too high, and the service life of the tool bit is prolonged. Based on deep learning, whether the tissue is broken or not is judged according to the slope, frequency, impedance and voltage of an impedance curve, and whether the tissue is broken or not can be recognized only by calling the model through a subsequent host program.
