Virtual surgery haptic information acquiring device

Abstract

The invention relates to a virtual surgery haptic information acquiring device in the technical field of virtual simulation, which comprises a bracket assembly, a slide assembly, an operation mechanism and a detecting module, wherein the slide assembly is fixedly arranged on the bracket assembly; the operation mechanism is movably connected with the slide assembly; and the slide assembly is connected with the operation mechanism and the detecting module to transmit a control command and a sensing signal. The invention can acquire the haptic information of small surgical instruments, such as asurgical needle, a scalpel, a clamp, and the like during organic tissue surgery operation, can acquire the force sense information of operation at different speeds, angles and heights, and provides simulation parameter data for a virtual surgery.

Description

Force sense information acquisition device for virtual surgery technical field The present invention relates to an information collection device in the field of virtual simulation technology, in particular to a force sense information collection device for virtual surgery. Background technique The development of modern science more and more reflects the intersection and penetration of multiple disciplines. The application of virtual reality in the medical field makes virtual surgery a research direction that is developing. Virtual surgery can help doctors formulate surgical plans; it can also be practiced repeatedly, reducing surgical training costs, and shortening the cycle of training surgeons. Virtual surgery overcomes the lack of operating opportunities and expensive operating objects encountered when training doctors relying on traditional clinical observation practices. The problem is of great significance to the training of medical surgery. The force feedback of ...
