Abstract

The invention discloses a hybrid virtual reality coincident positioning piece for a medical image and a hybrid virtual reality guidance method. The hybrid virtual reality coincident positioning piececomprises a positioning piece body (1) attached to a preset area of a chest of a patient, wherein at least three positioning points (2) are arranged on the positioning piece body (1); and the positioning piece body (1) is manufactured according to human body characteristics of the preset area of the chest of the patient, and is consistent with the human characteristics of the preset area. According to the positioning piece, the positioning piece body is manufactured according to the human body characteristics of the preset area of the chest of the patient, and is attached to the pre-set area of the chest of the patient, so that no offset occurs in the pre-operative shooting or intraoperative guidance, the medical image photographed before surgery can be directly positioned in the operation; and since the positioning piece body is attached to the preset area of the chest of the patient, the coincidence precision of the medical image is greatly improved, the operation time is saved, andthe operation quality is improved.

Description

technical field [0001] The invention relates to the related technical field of medical equipment, in particular to a mixed virtual reality superimposed positioning part for medical imaging images and a mixed virtual reality guiding method. Background technique [0002] Since the existing minimally invasive surgery cannot directly view the surgical site, the operator needs to rely on various surgical navigation systems to determine the information of the surgical site. [0003] Therefore, the existing surgical navigation system proposes to place markers somewhere in the patient before surgery, and then take medical images. Intraoperative position for coincidence navigation. [0004] However, in the existing surgical navigation system, the markers used are anchor points, and a plurality of anchor points are placed somewhere in the patient for marking during preoperative shooting. Then, intraoperatively, the anchors are repositioned in the same position on the patient for gui...
