Description

Technical Field

[0001] The present invention relates to the field of medical auxiliary equipment, and more specifically, to a pair of orthopedic glasses with enhanced display based on AR technology. Background Art

[0002] AR enhanced display is a technology that cleverly integrates virtual information with the real world, providing a richer user experience by "enhancing" the real world.

[0003] At present, AR enhanced display technology is widely used in the medical field. For example, when performing traumatic orthopedic surgery, it is necessary to determine the surgical area based on the patient's medical imaging photos. At the same time, during the operation, it is also necessary to observe the patient's medical imaging photos to determine the surgical plan. With AR enhanced display technology, doctors can use AR technology to simulate and plan traumatic orthopedic surgery. In the field of view of AR glasses, through aseptic gestures and air-to-air interactive operations, the three-dimensional image of the patient's spine can be flipped and scaled at will. Doctors can quickly lock the area, effectively improving the convenience and safety of doctors' operations. Under the guidance of AR glasses, surgical navigation and guidance are performed through markerless markings to improve the success rate of surgery.

[0004] In order to solve the problem that the micro-projection built into the existing AR glasses cannot be reasonably used in combination with the AR function and is not convenient to adjust the projection angle, the existing patent (Chinese utility model patent with announcement number CN210222366U) discloses a smart panoramic glasses based on AR augmented reality technology, which adjusts the projection height by extending and retracting the electric telescopic rod, and drives the plane angle adjustment of the mounting plate and the micro-projector below by rotating the output shaft; however, in actual use, although the existing technology can adjust the projection angle, the existing AR glasses are all head-mounted, usually with straps or the AR glasses and helmets are integrated to be worn on the user's head. Since AR glasses are usually much heavier than conventional glasses, the weight will act on the head and neck after being worn on the user's head. When performing surgery with AR glasses on, it is necessary to lower the head for a long time. Therefore, long-term wearing will cause fatigue of the doctor's head and neck, causing discomfort in the cervical spine, affecting the normal progress of the operation. Summary of the invention

[0041] like Figures 1 to 9As shown, an embodiment of the present invention provides orthopedic glasses based on AR technology enhanced display, including a head-mounted part 1, the head-mounted part 1 includes a shell 11, a head elastic band 12 fixedly connected to the outer surface of the shell 11, a projection module fixedly connected to the inside of the shell 11, and a display optical element 16 fixedly connected to one side of the shell 11 for displaying the image projected by the projection module (the projection module projects the image on the display optical element 16, and the AR glasses projection technology and principle are mature existing technologies, which are not repeated here), a microphone 17 is connected to the lower end of the shell 11, and a speaker 13 is connected to one side of the shell 11, a protective lens 15 for protecting the display optical element 16 is also connected to the inside of the shell 11, and a camera 14 is also fixedly connected to the inner wall of the shell 11,

[0042] The embodiment of the present invention further includes a wearing part 2 and two supporting units 3 connecting the lower end of the shell 11 with one side of the wearing part 2, wherein the wearing part 2 includes a strap 21, two shoulder straps 22 symmetrically fixed to the upper end of the strap 21, an arc seat 24 fixed to both ends of the strap 21, and a chest pad 23 fixed to one side of the arc seat 24;

[0043] The support unit 3 includes an insert block 31 connected to the inside of the shell 11, a ball head 32 rotatably connected to the lower end of the insert block 31, a support rod 33 fixed to the lower end of the ball head 32, a support rod 34 inserted into the inside of the support rod 33, a plurality of triangular limiting grooves 35 equidistantly arranged on the outer surface of the support rod 34, a limiting assembly 36 movably connected to the inside of the support rod 33 and used to cooperate with the triangular limiting grooves 35 to limit the support rod 34, a buffer portion 37 connected to the lower end of the support rod 34, a ball head 38 fixed to the lower end of the buffer portion 37, and a support portion 39 rotatably connected to the ball head 38, and the support portion 39 is located inside the arc seat 24.

[0044] The limiting assembly 36 includes a movable groove three 361 opened inside the support rod one 33, a movable seat 362 movably connected to the movable groove three 361, a limiting plate 364 fixedly connected to the outer surface of the movable seat 362, a spring five 367 located in the movable groove three 361 and sleeved on the outer surface of the movable seat 362, a triangular limiting block 363 fixedly connected to one side of the movable seat 362, a pulling end 365 fixedly connected to the other side of the movable seat 362 and penetrating the support rod one 33 and extending outward, and a through hole 366 opened inside the pulling end 365, and the two ends of the spring five 367 are respectively connected to one side of the limiting plate 364 and the inner wall of the movable groove three 361.

[0045] A movable groove 2 331 for accommodating the support rod 2 34 is provided inside the support rod 1 33, and one end of the support rod 2 34 is movably inserted in the movable groove 2 331. A spring 1 332 is provided in the movable groove 2 331, and the two ends of the spring 1 332 are respectively connected to the inner wall of the movable groove 2 331 and the top of the support rod 2 34.

[0046] By adopting the above technical solution, firstly, the two shoulder straps 22 are respectively lapped on the two shoulders of the user, and then the straps 21 are tied to the upper body of the user (by Velcro), so that the arc seat 24 and the chest pad 23 can be located in front of the user's chest, and then the head elastic band 12 is put on the top of the head so that the shell 11 can be located at the user's eyes, and the initial wearing is completed. Then, the length of the support unit 3 is adjusted. When the user needs to lower his head to observe the surgical area, the shell 11 is driven to move downward, and the shell 11 moves to the upper body. The downward movement will drive the support rod 1 33 to move downward. When the support rod 1 33 moves downward, the support rod 2 34 is retracted into the movable groove 2 331, and the spring 1 332 contracts. When the triangular limit block 363 in the support rod 1 33 moves to the triangular limit groove 35, the spring 5 367 can push the limit plate 364 and the movable seat 362 to move in the direction of the support rod 2 34, so that the triangular limit block 363 enters the triangular limit groove 35. When the triangular limit block 363 enters the triangular limit groove 35, the support rod 2 34 can only move downward. The support rod 34 cannot continue to move into the movable groove 331, so that the support rod 34 is limited, thereby supporting the shell 11, dispersing the weight of the shell 11, and reducing the pressure on the head and neck. If the length of the support unit 3 is long, pulling the pull-out end 365 can make the movable seat 362 and the triangular limit block 363 move, so that the triangular limit block 363 is moved out of the triangular limit groove 35, so that the support rod 34 can move up and down in the movable groove 331, and the support rod 34 can continue to be put into In the movable groove 231, a through hole 366 is opened inside the pulling end 365 to facilitate threading. By tying the wire system on the pulling end 365, it is only necessary to pull the wire body during adjustment, which makes adjustment more convenient. At the same time, since the upper end of the support rod 1 33 is rotatably connected to the plug block 31 through the ball head 1 32, and the lower end of the buffer part 37 is rotatably connected to the support part 39 through the ball head 2 38, the shell 11 and the plug block 31 can move flexibly on the support rod 1 33, and the arc seat 24 and the support part 39 can move flexibly on the buffer part 37.

[0047] like Figure 3 , Figure 7 and Figure 8As shown, the support portion 39 includes a support seat 396 rotatably connected to the ball head 38, a column 2 391 fixedly connected to the lower end of the support seat 396, two column 393 symmetrically fixedly connected to the lower end of the support seat 396, two springs 394 sleeved on the outside of the two column 393, a slider 392 fixedly connected to the lower ends of the column 2 391 and the column 3 393, and a limiting flange 395 fixedly connected to the lower end of the slider 392. A movable groove 1 241 is provided inside the arc seat 24, and the slider 392 is slidably connected in the movable groove 1 241. A slide groove 243 for accommodating the column 2 391 and a slide groove 1 242 for accommodating the column 3 393 are also provided inside the arc seat 24. A plurality of limiting grooves 244 for accommodating the limiting flange 395 are provided on the inner wall of the movable groove 1 241. One end of the spring three 394 is movably connected to the inner wall of the movable groove one 241 , and the other end of the spring three 394 is fixedly connected to the upper end of the slider 392 .

[0048] By adopting the above technical solution, when the user needs to turn his head, he first raises his head so that the headband 1 worn on the head will also be lifted up with the head. After the shell 11 is lifted up, it can drive the support rod 1 33 to slide on the support rod 2 34, so that the support rod 2 34 extends out of the support rod 1 33, and then the support rod 1 33 lifts the support rod 2 34. When the support rod 2 34 moves upward, it drives the column 2 391 and the column 3 393 to move upward. The column 3 393 moves upward and enters the slide groove 1 242. When the column 3 393 moves upward, it squeezes the spring 394 to make the spring 394 contract. When the column 3 393 and the column 2 391 move upward, they drive the slider 392 to move upward in the movable groove 1 241, and the limiting flange 395 moves out of the limiting groove 244. Then the head is turned again, and the headband 1 worn on the head moves as the head rotates. The shell 11 moves and drives the support unit 3 to move, and the support unit 3 moves and drives the support part 39 to slide in the arc seat 24. When the head is rotated to a suitable angle, the head is lowered again and the length of the support unit 3 is readjusted. At this time, the spring three 394 generates a force to push the slider 392 and the limiting flange 395 to move in the direction of the limiting groove 244. The limiting flange 395 enters the limiting groove 244. The slider 392 cannot slide in the arc seat 24 at this time, and the support part 39 is limited in the arc seat 24. The arc seat 24 moves with the movement of the support unit 3 and the shell 11. After moving and being positioned in the arc seat 24, the arc seat 24 can continue to support the support unit 3 and the head-mounted part 1. This design enables the support unit 3 to support the head-mounted part 1 while the head-mounted part 1 can also rotate with the rotation of the head, which is more flexible and convenient to use.

[0049] like Figure 6As shown, the buffer part 37 includes a seat body 371 fixedly connected to the lower end of the supporting rod 2 34, a movable groove 4 376 opened inside the seat body 371, a column 1 372 inserted in the movable groove 4 376, and a spring 2 373 located in the movable groove 4 376, and the two ends of the spring 2 373 are respectively connected to the upper end of the column 1 372 and the inner wall of the movable groove 4 376, and the lower end of the column 1 372 passes through the seat body 371 and is fixedly connected to the ball head 2 38. A buffer pad 1 374 is fixedly connected to the lower end of the seat body 371, and a buffer pad 2 375 is sleeved on the outer surface of the column 1 372.

[0050] By adopting the above technical solution, since the wearing part 2 needs to be worn on the upper body of the user, the chest of the wearer will rise and fall when breathing during the operation, which may affect the stability of the head-mounted part 1. Therefore, a buffer part 37 is provided to solve this problem. When the chest rises and falls, it can push the column 1 372 into the movable groove 4 376 to contract the spring 2 373. The spring 2 373 can play a buffering role. This design can prevent the support rod 1 33, the support rod 2 34 and the shell 11 from being affected by the rise and fall of the chest, so that the support unit 3 and the head-mounted part 1 are more stable during the operation.

[0051] like Figure 1 , Figure 2 and Figure 8 As shown, the interior of the arc seat 24 is also connected to a traction assembly 4, and the traction assembly 4 includes two synchronous wheels 41 rotatably connected to the interior of the arc seat 24 through a torsion spring, a synchronous belt 42 sleeved on the outside of the two synchronous wheels 41 and transmission connected to the synchronous wheels 41, and a slide 43 fixed on the outer surface of the synchronous belt 42. The lower end of the arc seat 24 is rotatably connected to a take-up wheel 44, and the upper end of the take-up wheel 44 penetrates into the arc seat 24 and is fixed to the lower end of one of the synchronous wheels 41. The slide 43 is slidably connected in a movable groove 241. A traction line 45 is wound on the take-up wheel 44, and the other end of the traction line 45 passes through the binding belt 21 and is fixed to the upper end of the shell 11.

[0052] By adopting the above technical solution, the number of traction components 4 is two and they are symmetrically arranged inside the arc seat 24. When the head turns left or right, the head-mounted part 1 will drive the support part 39 to move to one side in the arc seat 24. At this time, the movement of the arc seat 24 will push the slide seat 43 to move, and the movement of the slide seat 43 will drive the synchronous belt 42 to move. The movement of the synchronous belt 42 drives the two synchronous wheels 41 to rotate, and the rotation of one of the synchronous wheels 41 drives the take-up wheel 44 to rotate. The rotation of the take-up wheel 44 can take up and tighten the traction line 45, thereby applying an upward pulling force to the shell 11. In this way, when the shell 11 moves to the left, the traction line 45 on the left side is pulled tight. 5 can apply a force to the shell 11. When the shell 11 moves to the right, the traction line 45 on the right side can apply a force to the shell 11. The upward pulling force applied to the shell 11 is to lift the shell 11 and reduce the supporting burden of the support unit 3. For example, when the shell 11 moves to the right, after it moves to the right position, the support unit 3 on the left side below the shell 11 is subjected to a greater force, and the support unit 3 on the right side below the shell 11 may be tilted. At this time, it is necessary to apply a pulling force to the shell 11 to prevent the support unit 3 on one side below the shell 11 from failing to provide a good supporting force after the shell 11 rotates.

[0053] like Figure 6 As shown, a movable groove six 18 is opened inside the shell 11, and the insert block 31 is inserted in the movable groove six 18 and limited by the positioning component 5 in the shell 11, the positioning component 5 includes a movable groove five 51 opened inside the shell 11, a limiting column 52 movably inserted in the movable groove five 51, and a spring four 53 sleeved on the outside of the limiting column 52, and the two ends of the spring four 53 are respectively connected to the outer surface of the limiting column 52 and the inner wall of the movable groove five 51, and a positioning groove 311 for accommodating the limiting column 52 is opened inside the insert block 31.

[0054] By adopting the above technical solution, by pulling the limit column 52 and moving it to the outside of the shell 11, one end of the limit column 52 can be removed from the positioning groove 311 in the plug block 31. At this time, the limit on the plug block 31 can be cancelled, and the plug block 31 can be quickly pulled out of the movable groove 6 18, thereby realizing the rapid disassembly and installation of the plug block 31.

[0055] The working process of the technical solution provided by the present invention is as follows:

[0056] First, the two shoulder straps 22 are respectively overlapped on the user's two shoulders, and then the straps 21 are tied to the user's upper body so that the arc seat 24 and the chest pad 23 can be located in front of the user's chest, and then the head elastic band 12 is put on the top of the head so that the shell 11 can be located at the user's eyes to complete the initial wearing, and then the length of the support unit 3 is adjusted. After the adjustment is completed, one end of the support unit 3 is against the arc seat 24, and the other end of the support unit 3 supports the shell 11. When the user needs to turn his head, he first raises his head so that the headband 1 worn on the head will also be lifted up with the head. When the shell 11 moves upward, it drives the support unit 3 to move upward, so that the second column 391 and the third column 393 move upward, and the third column 394 moves upward. When 393 and column two 391 move upward, they drive the slider 392 to move upward in the movable groove one 241, and the limiting flange 395 moves out of the limiting groove 244. Then the head is rotated, and the head-mounted part 1 worn on the head moves with the rotation of the head. The movement of the shell 11 drives the support unit 3 to move, and the movement of the support unit 3 drives the support part 39 to slide in the arc seat 24. When the head is rotated to a suitable angle, the head is lowered again to readjust the length of the support unit 3. The spring three 394 generates a force to push the slider 392 and the limiting flange 395 to move in the direction of the limiting groove 244. The limiting flange 395 enters the limiting groove 244. At this time, the slider 392 cannot slide in the arc seat 24, and the rotation adjustment is completed.
