Fulcrum device for virtual oral surgery

Abstract

The invention relates to a fulcrum structure of a virtual surgery training system, in particular to a fulcrum device for a virtual oral surgery. The fulcrum device comprises a supporting base, a rotary locking assembly, a rotary plate frame, a sliding frame body, a sliding locking bar, a first simulation supporting rod and a second simulation supporting rod; the rotary plate frame is rotationally connected to the upper portion of the supporting base through the rotary locking assembly, a rotary head plate is arranged on the front portion of the rotary plate frame, an outward-extending sliding plate is arranged on the rear portion of the rotary plate frame, side racks are arranged on the left side and the right side of the outward-extending sliding plate, and the sliding frame body is installed on the upper portion of the outward-extending sliding plate in a sliding mode; and the sliding frame body is of a square frame structure. The mechanism movement of the fulcrum device is subjected to movement design by adopting a polar coordinate movement mode, so that the overall dynamic characteristic of the fulcrum device is better, more labor is saved in operation and use, and the fulcrum device is suitable for external suspension type movement positioning operation at one end.

Description

technical field [0001] The invention relates to a fulcrum structure of a virtual surgery training system, in particular to a fulcrum device for virtual oral surgery. Background technique [0002] In dental oral surgery training operations, trainees usually use plaster or resin models for surgical operation training. This method of operating training through physical objects has seriously affected the operation due to the low reuse rate and the unrealistic operating environment. The effect of operation training consumes a lot of financial and material resources, and it is difficult to obtain the expected training effect. With the development of computer virtual reality technology, more and more training occasions are using computer virtual operation training to replace the original training mode. In the process of virtual training, virtual images are generally used to simulate the surgical environment. However, due to the particularity of oral surgery, a large number of forc...
