Laparoscopic surgery simulation training system based on computer aided medical display

Abstract

The invention discloses a laparoscopic surgery simulation training system based on computer aided medical display. A CT data preprocessing module, a CT organ segmentation module and a three-dimensional volume rendering module can use artificial intelligence and a 3D volume rendering integrated rendering technology to construct a three-dimensional abdominal cavity model in real time according to customized CT scan data of a patient. A volume data mechanics loading module, a joystick control module and a joystick mechanics feedback module are used to establish an accurate force feedback model and a tissue deformation model. Simulated actual laparoscopic surgical instruments are used and the joystick mechanics feedback module is combined to truly simulate the operation position and operationmode of surgical instruments. The real-time stress state of organs and tissues can be accurately fed back. Soft tissue deformation or a cutting effect can be truly reproduced. The system can accumulate real operation experience for a laparoscopic operator, can improve the operation skills of the laparoscopic operator, and can help the laparoscopic operator to be proficient in the relative depth ofa surgical instrument and a lesion organ.

Description

technical field [0001] The invention relates to the technical field of biomedical laparoscopy, in particular to a laparoscopic surgery simulation training system based on computer-aided medical display. Background technique [0002] With the rapid development of medical technology, more and more patients choose to use laparoscopic surgery instead of open surgery to complete treatment. Laparoscopic surgery is a new type of minimally invasive surgery. During the operation, the doctor makes 2-5 incisions with a diameter of 4-8mm in the abdomen of the patient. The laparoscope and surgical instruments are inserted into the abdominal cavity through the incision through the cannula. , The laparoscope takes images in the abdominal cavity, and sends the images to the terminal for display, and the doctor controls the surgical instruments according to the images displayed on the terminal, so as to perform operations on the diseased organs. Compared with open surgery, laparoscopic surg...

Problems solved by technology

In addition, due to the decrease in operational flexibility and the limitation of the surgical field, the surgeon's understanding of the lesion will have a great impact on the efficiency and even the success rate of the operation.

Therefore, if the laparoscopic operator does not have proficient operating skills, skilled operating skills, lack of operating experience, and cannot well perceive the relative depth of the surgical instrument and the lesion organ, the risk of laparoscopic surgery will be greatly increased.
