Technical Field
[0001] This invention relates to the field of image projection technology, and in particular to a stereoscopic image projection device for VR surgery. Background Technology
[0002] Surgery refers to the treatment performed by doctors on a patient's body using medical instruments, such as cutting and suturing. It is an operation performed on a local part of the human body with instruments such as knives, scissors, and needles to maintain the patient's health. It is the main treatment method in surgery and is commonly known as "opening the knife". Its purpose is to treat or diagnose diseases, such as removing diseased tissue, repairing damage, transplanting organs, and improving the body's function and morphology. VR surgical stereoscopic image output devices are needed during the surgical process.
[0003] The existing VR surgical teaching projection equipment specifically includes "a projector unit, a holographic screen unit, and a host computer in the teaching room, and a video recording and broadcasting unit and a host computer in the operating room. The output side of the projector unit is located within the receiving range of the holographic screen unit, and an adjustment component is fixedly connected to the end of the projector unit. The projector unit, the holographic screen unit, and the host computer in the teaching room are electrically connected."
[0004] The aforementioned prior art also has the following drawbacks: the image output device in the prior art lacks good support and placement measures, and it is inconvenient to adjust the direction of the projection board or projection cloth, which cannot meet the needs of different usage environments and brings certain limitations to the user's use. Therefore, we propose a stereoscopic image projection device for VR surgery. Summary of the Invention
[0005] The present invention proposes a stereoscopic image projection device for VR surgery that can meet the needs of different usage scenarios. Moreover, when adjusting the projection panel, the height and horizontal position of the projector can be automatically adjusted without manual adjustment.
[0006] In order to achieve the above object, the present invention adopts the following technical solutions:
[0007] A VR surgical stereoscopic image projection device includes a support frame. A dual-axis motor is fixedly connected to one side of the support frame. A rotating shaft is fixedly connected to the right output shaft of the dual-axis motor. A projection plate is fixedly connected to one end of the rotating shaft. First arc-shaped plates are provided on both sides of the projection plate. A second arc-shaped plate is provided on the top of the projection plate. A top plate is provided above the second arc-shaped plate. Two guide rods are movably sleeved inside the top plate. A movable plate is fixedly connected to one end of each guide rod. A projector is provided at the bottom of the movable plate. A transverse movement assembly is provided at the end of each guide rod away from the movable plate. A transmission assembly is provided between the dual-axis motor and the transverse movement assembly. The transverse movement assembly includes a vertical plate fixedly connected to the guide rod. A screw is threaded inside the vertical plate. A bearing is fixedly sleeved on the outside of the screw, and the bearing is fixedly connected to the top plate. The transmission assembly includes pulleys fixedly connected to the dual-axis motor and the screw. A belt is sleeved on the outside of the two pulleys.
[0008] Preferably, the top of the support frame has two lifting slots, and a lifting rod is movably fitted inside the lifting slot, with the top end of the lifting rod fixedly connected to the top plate.
[0009] Preferably, the top plate has a through hole, and two guide holes are provided on one side of the top plate, with the guide rod passing through the guide holes.
[0010] Preferably, a positioning bearing is fitted on the left side of the rotating shaft, and the positioning bearing is fixedly connected to the support frame.
[0011] Compared with existing technologies, the beneficial effects of this invention are as follows: This invention utilizes a structure including a support frame, a dual-axis motor, a projection board, a first arc-shaped plate, a second arc-shaped plate, a top plate, a moving plate, a projector, a horizontal movement component, and a transmission component. The dual-axis motor drives the projection board to rotate, allowing for horizontal or vertical projection. During adjustment, the height of the top plate is simultaneously adjusted via the first and second arc-shaped plates. Simultaneously, the transmission and horizontal movement components drive the moving plate to move horizontally, facilitating the adjustment of the projector's horizontal position. This solution features a simple structure, novel design, and the ability to adjust the projection board's display direction, enabling both horizontal and vertical displays to meet the needs of different usage scenarios. Furthermore, the height and horizontal position of the projector are automatically adjusted during projection board adjustments, eliminating the need for manual adjustment.

[0017] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.
[0018] Reference Figure 1-4 A VR surgical stereoscopic image projection device includes a support frame 1. A dual-axis motor 2 is fixedly connected to one side of the support frame 1. A rotating shaft 3 is fixedly connected to the right output shaft of the dual-axis motor 2. A projection plate 4 is fixedly connected to one end of the rotating shaft 3. First arc-shaped plates 5 are provided on both sides of the projection plate 4. A second arc-shaped plate 6 is provided on the top of the projection plate 4. A top plate 8 is provided above the second arc-shaped plate 6. Two guide rods 9 are movably fitted inside the top plate 8. A movable plate 10 is fixedly connected to one end of the guide rod 9. A projector 11 is provided at the bottom of the movable plate 10. A transverse movement component is provided at the end of the guide rod 9 away from the movable plate 10. A transmission component is provided between the dual-axis motor 2 and the transverse movement component. The dual-axis motor 2 drives the projection plate 4 to rotate, and at the same time, it drives the transverse movement component to work through the transmission component. The transverse movement component drives the projector 11 to move, so that manual adjustment is not required.
[0019] like Figure 1 As shown, the transverse component includes a vertical plate 12 fixedly connected to the guide rod 9. A screw 13 is threaded inside the vertical plate 12, and a bearing 14 is fixedly fitted on the outside of the screw 13. The bearing 14 is fixedly connected to the top plate 8. The rotation of the screw 13 drives the vertical plate 12 to move, and the vertical plate 12 drives the guide rod 9 to move.
[0020] like Figure 1 As shown, the transmission assembly includes pulleys 15 fixedly connected to the dual-axis motor 2 and the screw 13. Belts 16 are sleeved on the outside of the two pulleys 15. The dual-axis motor 2 drives the screw 13 to rotate by means of the pulleys 15 and the belts 16.
[0021] like Figure 4 As shown, the top of the support frame 1 has two lifting slots. The lifting rod 7 is movably fitted inside the lifting slot, and the top of the lifting rod 7 is fixedly connected to the top plate 8. The lifting rod 7 moves up and down inside the lifting slot.
