Medical instrument movement control system and method

Abstract

The invention discloses a medical instrument movement control system and method.The medical instrument movement control system comprises a safety switch used for confirming the operation state of a user in real time and forming a first electric signal for output according to the operation state of the user. Before the control unit controls the driving motor to complete corresponding power output, the safety switch is used for judging the operation intention of a user, and the medical instrument is driven to move only when it is judged that the user has the operation intention, so that the movement control safety of the medical instrument is improved; meanwhile, before the control unit controls the driving motor to complete corresponding power output, misoperation removal is conducted on the expected power output state of the driving motor, abnormal movement, caused by accidental collision and accidental touch, of the medical instrument is avoided, and the movement control safety and stability of the medical instrument are further improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, and in particular, to a system and method for moving control of medical devices. Background technique [0002] Minimally invasive surgery refers to a surgical method that uses modern medical instruments such as laparoscope and thoracoscope and related equipment to perform surgery inside the human cavity. Compared with traditional surgical methods, minimally invasive surgery has the advantages of less trauma, less pain, and faster recovery. However, the minimally invasive instruments in minimally invasive surgery are limited by the size of the incision, which greatly increases the difficulty of the surgical operation, and the fatigue and tremors of the doctor during the long-term operation will be amplified, which restricts the development of minimally invasive surgery technology. The key factor. With the development of robotic technology, a new technology in the field of minimally invas...

Problems solved by technology

[0006] 1. In the above control scheme, the user will directly move the trolley by pushing or twisting the handle. There is no safety strategy, and it is easy to cause safety accidents when accidental touch occurs;

[0007] 2. In the above control scheme, no abnormal judgment is made when the torque sensor and the tension and pressure sensor receive a large input signal. Manipulating equipment to move, there are potential safety hazards
