Problems solved by technology

[0003] However, the popularization of robot-assisted minimally invasive surgery technology is not achieved overnight. Some factors limit the popularization of robot-assisted minimally invasive surgery technology. The price of a surgical robot in China is 20 million yuan. The high cost of equipment makes it impossible for most hospitals to purchase surgical robots or patients cannot afford the high cost of surgery; doctors who perform robot-assisted minimally invasive surgery need to undergo strict and systematic training , and the operation method of robot-assisted surgery is quite different from that of traditional minimally invasive surgery. The doctor's operating habits must undergo long-term training to adapt to the operation method of robot-assisted surgery.

Embodiment approach

[0030] The controller includes a safety control module, and the working steps of the safety control module include:

[0031] During the rotation of the driving motor 101, the safety monitoring module reads the current signal output by the driving motor and compares it with the set value. When the actual current value of the motor exceeds the preset value, the safety monitoring module outputs a stop signal to control the driving motor to stop moving, so that The master-slave mapping corresponding to the handle driving device and the end motion joint part is automatically cut off, ensuring that the driving steel wire is not broken and avoiding the excessive force of the minimally invasive surgical intelligent instrument of the present invention on human tissue and damaging the tissue; as well as

[0032] When the handle and the rotation base are moving, the safety monitoring module reads the position signals of the deflection potentiometer 113 and the rotation potentiometer 119,...

Embodiment 1

[0056] (1) Hand-held intelligent instruments for minimally invasive surgery allow the terminal motion joints of the instrument to enter the human body for surgical operations. The hand-held operation process includes operating the handle drive device of the instrument by hand, and then how free the space of the detected hand-operated handle drive device is. The high-speed motion control signal is output to the drive motor through the controller and the driver;

[0057] Specifically include the following steps:

[0058] Manually turn the handle 116 of the handle drive device, detect the rotation angle and speed of the handle 116 through the deflection potentiometer 113 installed on the rear end of the handle, and send an I / O signal to the controller, and the controller converts the I / O signal into deflection The motion control signal is sent to the driver, and the driver transmits the control signal to the first drive motor 101, and the first drive motor 101 starts; The rotati...

Abstract

The invention discloses a surgery operational method by adopting an intelligentized minimally invasive surgery instrument. The method comprises the following steps that 1, the intelligentized minimally invasive surgery instrument is held in hand, and a tail-end motion joint of the instrument is made to enter into a human body for conducting the surgery operation, wherein the hand-holding operation process comprises the steps of operating a handle driving device of the instrument by hand, and then outputting a detected space multi-freedom-degree motion control signal of the hand-operated handle driving device to a driving motor; 2, according to the space multi-freedom-degree motion control signal, the driving motor drives a transmission device to move to transmit the hand operation motion to the tail-end motion joint, and the tail-end motion joint outputs space multi-freedom-degree motion. By the adoption of the intuition operation in the method, the equipment cost is low, the maintenance cost and use cost are high, the operation technical requirements for a doctor are low, and the method conforms to operational habits of the doctor.

Description

technical field [0001] The invention relates to an intelligent instrument for minimally invasive surgery, in particular to a surgical operation method using the intelligent instrument for minimally invasive surgery. Background technique [0002] During robot-assisted minimally invasive surgery, doctors perform surgical tasks with the help of slender minimally invasive surgical instruments. One end of the surgical instrument is placed on the quick-change interface device at the end of the robot's operator's hand, and the other end is inserted into the body through a tiny incision on the surface of the human body for surgical operations. Therefore, the surgical instrument is the only part in contact with the human diseased tissue. It is also the part of the robot that directly performs the surgical operation. In the implementation of surgery, in order to meet the action requirements of different surgical operation tasks (clamping, suturing, knotting, etc.), the robot should r...
