Detailed Implementation

[0031] The present invention will now be described in further detail with reference to the accompanying drawings.

[0032] Please see Figure 1-7 As shown, this embodiment provides an auxiliary surgical positioning device with automatic angle adjustment, including a surgical positioning device body 1, a limiting device installed inside the surgical positioning device body 1, a clamping device 4 installed at the bottom of the surgical positioning device body 1, an adjusting device 2 installed at the top of the surgical positioning device body 1, and a telescopic device 5 installed on the surface of the adjusting device 2.

[0033] The telescopic device 5 includes a fixed rod 501, which is rotatably fitted to one side of the adjusting device 2. Both ends of the fixed rod 501 are equipped with limiting plates 502. A pull rod 503 is slidably fitted inside the limiting plate 502. An adapter block 513 is installed at one end of the pull rod 503 extending into the limiting plate 502. A U-shaped push rod 510 is slidably fitted inside the limiting plate 502. A second spring 511 is installed inside the limiting plate 502. The end of the second spring 511 near the U-shaped push rod 510 is fixedly connected to the U-shaped push rod 510. A third spring 512 is installed inside the limiting plate 502. The end of the third spring 512 near the adapter block 513 is fixedly connected to the adapter block 513. A limiting groove 509 is opened inside the limiting plate 502. The adapter block 513 is in contact with the U-shaped push rod 510.

[0034] One application of this embodiment is as follows: During use, medical personnel place the main body 1 of the surgical positioning device at the required position on the operating table. The medical personnel rotate the fixing bolt 3 402, which causes the moving block 405 to move. The moving block 405 then causes the clamping plate 404 to rotate. When the clamping plate 404 contacts the operating table, the main body 1 of the surgical positioning device is fixed. The medical personnel then rotate the rotating rod 204, which causes the rotating block 205 to rotate. The rotating block 205 then causes the fixing rod 501 to rotate, which in turn causes the rotating rod 3 207 to rotate. The motion drives the fixing device 3 to rotate. When the fixing device 3 moves to the position required by the medical staff, the medical staff rotates the two fixing bolts 206 and then the fixing bolt 302 to adjust the placement block 304. After the placement block 304 is adjusted, the medical staff rotates the fixing bolt 302 again to fix the placement block 304. When it is necessary to adjust the rotating rod 207, the medical staff pulls the pull rod 503, causing the pull rod 503 to disengage from the slot 506. The medical staff then pulls the support rod 504, and the movement of the support rod 504 drives the rotating rod 207 to move. The movement of the rotating rod 207... When the moving fixing device 3 moves, and the locking rod 505 moves into the limiting groove 509 on the other end limiting plate 502, the locking rod 505 moves and pushes the U-shaped push rod 510 to move. Under the action of the spring 512, the pull rod 503 moves downward. When the pull rod 503 moves into the locking groove 506, the locking rod 505 can be fixed, thereby retracting the fixing device 3. When medical staff need to extend the fixing device 3, the same operation as above can be used to extend the fixing device 3. When medical staff need to rotate the rotating rod 202, the medical staff pull the sliding rod 102, and the sliding rod 102 moves to drive the rotation. When tooth 103 moves and disengages from the limit of gear 105, medical staff start drive motor 201. The output end of drive motor 201 rotates, causing rotating rod 1 202 to rotate. Rotating rod 1 202 rotates, causing rotating rod 2 204, fixed rod 501, rotating rod 3 207 and fixing device 3 to move. After the fixing device 3 is adjusted, medical staff turn off drive motor 201 and release sliding rod 102. Under the action of spring 4 104, sliding rod 102 moves, causing tooth 103 to move. When tooth 103 moves to mesh with gear 105, the limit of rotating rod 1 202 is completed.

[0035] The adjustment device 2 in this embodiment includes a drive motor 201, which is installed at the bottom of the main body 1 of the surgical positioning device.

When medical personnel start the drive motor 201, the output end of the drive motor 201 rotates, causing the rotating rod 202 to rotate. The rotation of the rotating rod 202 causes the rotating rod 204, the fixed rod 501, the rotating rod 207, and the fixing device 3 to move. After adjusting the fixing device 3, the medical personnel turn off the drive motor 201.

[0036] The limiting device in this embodiment includes a sliding rod 102. A sliding groove 101 is provided inside the main body 1 of the surgical positioning device.
