Abstract

The invention discloses a virtual surgery simulation system based on force feedback and belongs to a virtual surgery simulation system. The virtual surgery simulation system based on force feedback comprises a single-degree-of-freedom manipulator, a control circuit and a power supply, wherein the single-degree-of-freedom manipulator comprises a manipulator, a moment motor, a position sensor, a force sensor, a motor supporting tray and a chassis; and the control circuit comprises a signal conditioning circuit, a data acquisition card, a collision detection module, a soft tissue deformation computing module, a display module, a feedback force computing module, a singlechip, a peripheral circuit of the singlechip and a motor drive circuit. The virtual surgery simulation system utilizes information feedback of various sensors to establish an environmental model which is interactive with operators and tasks through a human-computer interactive device, provides a direct-viewing and friendly human-computer interface, and has high operation precision and operation reliability, so that patients and the system are safe; and the operative process is displayed in real time, so that operation failure is reduced.

Description

technical field [0001] The invention relates to a virtual surgery simulation system, in particular to a force feedback-based virtual surgery simulation system. Background technique [0002] In traditional surgical operations, on the one hand, doctors have to go through long enough training to master them proficiently; , the effect of surgical training is not very good. In the virtual surgery simulation system, medical personnel can immerse themselves in the virtual surgery environment generated by the computer, experience and learn how to perform various operations through the virtual surgery simulator, and develop the ability to deal with various emergencies. Doctors can repeat various necessary operation training according to their own needs, and can get the guidance of expert operation system established according to expert experience, which greatly saves the cost and training time of training medical personnel, so as to achieve rapid improvement of learners' surgical sk...
