Problems solved by technology

At present, there are also some systems or methods for virtual surgery training, but most of the human organ models trained by them are designed by related software, and the authenticity is not strong, and the training is carried out in the form of tutorial training, which is relatively strong in theory and is not related to reality. There is still a big gap in clinical operations

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, a medical minimally invasive surgery training system based on mixed reality includes a master unit 1 , a video image acquisition and transmission unit 2 , a video image reception and display unit 3 and a slave unit 4 . in,

[0018] Active end unit 1: includes a computer and a multi-degree-of-freedom operating handle connected to the computer with force feedback. The computer has a virtual surgery scene, which is a real human organ model obtained through scanning and post-processing The data is imported into the simulation software and built. The operator controls the surgical instruments in the computer virtual surgical scene by operating the multi-degree-of-freedom operating handle with force feedback, thereby completing the virtual surgical process. The multi-degree-of-freedom operating handle is a With force feedback, th...

Abstract

The invention discloses a medical minimally-invasive operation training system based on mixed reality. The system comprises a master end unit, a video image acquisition and transmission unit, a video image reception and display unit and a driven end unit. When the master end unit carries out virtual operation, the driven end unit can realize operation which is synchronous and exactly same with the operation of the master end unit, and manipulation information of operation instruments when the master end unit carries out operation can be sensed through a handle of the driven end. Through the video image acquisition and transmission unit, operation process of personnel at the master end can be collected and transmitted to a displayer of the driven end, and trainees at the driven end can sense the manipulation information of the operation instruments at the master end, and meanwhile, can observe overall operation process of an operator at the master end. The beneficial effects of the training system are that through the mixed-reality operation course, medical minimally-invasive surgery training, which is high in sense of reality, is realized, and the system provides a good training platform for hospitals and medical colleges.

Description

technical field [0001] The invention relates to a medical minimally invasive surgery training system based on mixed reality, which belongs to the fields of biomedicine and information technology. Background technique [0002] Since the 20th century, minimally invasive surgery technology represented by laparoscopic technology has developed rapidly. Compared with traditional surgery, minimally invasive surgery has the advantages of less trauma, faster recovery, and shorter anesthesia time. Therefore, minimally invasive surgery has been widely used. And development. However, due to the local characteristics of minimally invasive surgery, doctors can only see the local conditions of the patient through the endoscope, which greatly increases the difficulty of surgery for doctors, and the dependence on experience is higher than traditional surgery. For doctors, preoperative training is very important. Generally, when doctors conduct minimally invasive surgery training, they use ...
