Problems solved by technology

And this kind of plan requires more experience of doctors, and the traditional preoperative planning can only be planned based on two-dimensional images, and it is necessary to explore the surgical path and constantly adjust the path during the operation
At this stage, there are some 3D preoperative planning based on 2D image reconstruction and virtual reality preoperative planning, but they are not realistic enough.

Abstract

The invention discloses an operation rehearsal and teaching system based on force feedback and virtual reality. The operation rehearsal and teaching system is characterized in that the system comprises a three-dimensional reconstruction unit, a finite element mechanical analysis unit, a force feedback unit, a PC unit, a wireless communication module unit and a virtual glasses unit. Through combination of force feedback and virtual reality, real vision and touch of doctors and medical students in simulation surgery are provided, different virtual surgeries can be replaced to obtain different hand feelings, the medical college students can have more realistic feelings during training or doctors in surgery simulation drilling, and the purpose that a user can be subjected to operation trainingby being immersed in a virtual reality environment is achieved. According to the invention, reconstructed cases and scenes can be repeatedly practiced and used, resources are saved, and a user is helped to continuously refine own skills, so the efficiency of preoperative planning of doctors and operation teaching of medical students is greatly improved, and the operation risk is reduced.

Description

technical field [0001] The invention relates to the field of medical innovation technology, in particular to an operation rehearsal and teaching system based on force feedback and virtual reality. Background technique [0002] Traditional surgical training and programs are being performed on large numbers of live animals and specimens. These training methods pose many problems. The material required for training is sparse, and it is impossible to repeat the process on the same object if necessary until the student has properly learned the function. Virtual reality technology is a simulated experience from which one can get similar or completely different from the real world. Applications of virtual reality can include entertainment and educational purposes. The combination of virtual reality technology and surgical teaching is possible. [0003] The traditional preoperative planning is to obtain the images of the patient's lesion before the operation, and then combine the ...
