Virtual operation training system

Abstract

The invention belongs to the technical field of auxiliary surgical equipment, and particularly relates to a virtual operation training system. The virtual operation training system comprises a holographic projection system for displaying human tissues and organs through a 3D technology, a simulation surgical instrument for simulating a real surgical instrument handle, a scalpel simulation system constructed by utilizing three-dimensional modeling, a virtual operation output module, a central processing unit and a sensor device, the simulation surgical instrument comprises a far-section moduleand a near-section module, and the far-section module is similar to a mechanical arm structure and is provided with a wrist joint, an elbow joint, a shoulder joint and an extension rod; the near-segment module is sequentially composed of a knob and an elastic clamp with an outward opening, the rotating angle of the knob can be set to be a plurality of segments, one angle corresponds to projectionof one surgical instrument, and therefore conversion of different instruments is achieved in the virtual surgical training system. The system is sensitive in design and convenient to use, a vivid operation environment is created from multiple dimensions of visual touch, and the system has wide application value.

Description

technical field [0001] The invention relates to the technical field of auxiliary surgery equipment, in particular to a virtual surgery training system. Background technique [0002] Surgery is an important means of disease treatment. Due to the complex structure of various tissues and organs of the human body and changes in the normal anatomical structure caused by diseases, surgery has certain risks and requires a high level of knowledge and technical level of the surgeon. For the consideration of medical ethics, the surgical training in the previous medical education system was mainly animal surgery or isolated tissue surgery simulation, which had a long learning curve and was difficult to learn. Using the virtual surgery system, medical personnel can practice before performing complex operations on patients, shortening the learning curve, improving the technical level, and ensuring medical safety; patient images obtained by imaging equipment can also be imported into the ...

Problems solved by technology

However, most of the research in this field is limited to the visualization stage of simulation, which often lacks realistic visual and tactile effects, resulting in a large difference between the operation performed by medical personnel in the virtual environment and the clinical environment.
