Problems solved by technology
[0004]
1. During the operation, the doctor has to switch the field of view back and forth between the patient and the screen, which is very inconvenient and affects the continuity of the operation
[0005]
2. Unable to intuitively display 3D images, which affects the judgment of medical staff
[0006]
3. The blood vessels in the patient's body detected by the scan cannot be displayed on the patient's body surface, which is not conducive to guiding the medical staff's puncture intervention operation

The invention discloses an interventional puncture guiding device based on a VRAR virtual imaging technology, firstly, a virtual imaging cover can converge and refract patterns on a display at the bottom to the middle end of the interior, namely, image animation is displayed, so that medical staff can observe the images more visually, secondly, a first stepping motor and a second stepping motor are matched with each other, and therefore the interventional puncture guiding effect is improved. The angle of the projection plate can be adjusted, a plurality of LED projection light sources at the bottom of the projection plate can conveniently irradiate the body surface of an intervention area of a patient, the purpose of AR imaging is achieved, medical staff can be helped to conduct intervention puncture through images of the body surface, the guiding purpose is achieved, and finally the ultrasonic receiving probe can receive ultrasonic waves. The ultrasonic scanning detection data of the body of a patient can be collected conveniently, subsequent three-dimensional image establishment is facilitated, the molding metal frame can be pulled to move and perform molding positioning, medical staff can adjust the position of the ultrasonic receiving probe conveniently, and the data collection result is improved.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to an interventional puncture guide device based on VRAR virtual imaging technology. Background technique [0002] At present, in clinical practice, ordinary B-ultrasound shows two-dimensional cross-sectional images. Two-dimensional images have many limitations in surgery, especially in the puncture process. Only visible on the ultrasound image plane. This means that, in most cases, the doctor cannot see the tip of the needle on the ultrasound plane, making it difficult to move it accurately to the target area. [0003] According to the above, there have been some research and improved surgical navigation systems, such as TUSS (Queen's University, Canada) mentioned in the paper "Spinal Needle Navigation by Tracked Ultrasound Snapshots", but they all use computer screens to display navigation information, such as three-dimensional surgical paths and surgical instruments. Ul...
