Operation mapping proportion adjustment method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides an operation mapping proportion adjustment method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a motor operation current corresponding to a target instrument in a preset time period; under the condition that the motor running current is larger than a preset current threshold value and the duration reaches a preset duration threshold value, adjusting the operation mapping proportion of the target instrument to be a first operation mapping proportion; and determining the preset current threshold according to the no-load running current of the motor. Thus, whether the instrument collides with the biological tissue or not can be judged through the running current of the motor, the mapping proportion can be adjusted in time, the operation mapping proportion of the operation handle and the tip end of the instrument is flexibly adjusted, instrument operation is more refined, tissue damage caused by too large operation amplitude can be prevented, the use safety of the endoscopic instrument is improved, and the requirements of various scenes can be met.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an operation mapping ratio adjustment method, device, electronic equipment and storage medium. Background technique [0002] With the continuous development of science and technology, intelligent medical equipment plays an increasingly important role in various medical scenarios, such as the endoscopic instrument control system in abdominal minimally invasive surgery, which can display the patient's internal images in real time through the endoscope At the same time, instruments are used to perform corresponding operations on the tissue to ensure the normal and safe operation of the operation. [0003] The endoscopic instrument control system collects the moving position signal of the operating handle, and controls the instrument to make corresponding movements according to the moving distance of the handle. In the prior art, the mapping ratio between the moving distance ...
