[0002] The dura suspension technique is that the doctor first determines the projection of the lesion on the scalp, and then makes a horseshoe-shaped incision with the projection as the center point. The scalp is first cut, and the muscles are cut if there are any, so that the skull is exposed. Subsequently, an electric drill is used to drill a hole at each corner of the skull, and the skull is milled open with a milling cutter to expose the dura mater. The dura mater is then suspended on the bone edge with a wire to prevent dura mater peeling and causing epidural hematoma.

[0003] Chinese patent CN115444584B discloses a dura mater suspension drilling protection device for craniotomy.

[0022] Example 2 Please refer to Figure 1-Figure 2 As shown, the lateral adjustment mechanism 2 includes a first screw rod 201, a first guide rod 202, a lifting seat 203 and a first stepper motor 204. The first screw rod 201 is rotatably connected to the inside of the first frame 102, the first guide rod 202 is fixedly connected to the inside of the first frame 102, the lifting seat 203 is threadedly connected to the outer surface of the first screw rod 201, and the lifting seat 203 is slidably connected to the outer surface of the first guide rod 202. The first stepper motor 204 is fixedly installed on the top of the first frame 102, and the output end of the first stepper motor 204 extends to the inside of the first frame 102 and is fixedly connected to the first screw rod 201. The lifting seat 203 is internally rotatably connected with two sets of connecting rods 205, and the outer surface of the connecting rod 205 is sleeved with a sliding plate 103.

[0023] Those skilled in the art can understand that, by driving the first screw rod 201 to rotate through the output end of the first stepper motor 204, the lifting seat 203 moves up and down. Since the first stepper motor 204 is provided on both sides, the heights of the lifting seats 203 on both sides can be inconsistent by controlling the output ends of the two groups of first stepper motors 204, so that the two groups of connecting rods 205 are in an inclined state, driving the sliding plate 103 to slide toward the lower part of the connecting rod 205.

[0024] Example 3 Please refer to Figure 3 and Figure 7As shown, the storage mechanism 3 includes a rotating disk 301, the bottom of which is fixedly connected to the output end of the first driving motor 107, the interior of the rotating disk 301 is hollow, a plurality of groups of strip grooves 302 are opened through the top of the rotating disk 301, a placement groove 303 is opened in the middle of the strip grooves 302, a plurality of groups of first screws 305 are arranged inside the rotating disk 301, both ends of the first screws 305 are rotatably connected to the inside of the fixed block 304, and the fixed block 304 is welded to the inner bottom end of the rotating disk 301.

[0025] Please refer to Figure 7 As shown, the threads at both ends of the first screw 305 have opposite rotation directions, and both ends of the outer surface of the first screw 305 are threadedly connected with movable parts 308, the top of the movable part 308 passes through the strip groove 302, and is fixedly installed with a first clamping part 309, the movable part 308 is slidably connected to the first fixed rod 306, and the two ends of the first fixed rod 306 are respectively fixedly connected to the inner walls of the two groups of fixed blocks 304, one end of the first screw 305 is fixedly connected with a transmission gear 307, and the inner bottom end of the rotating disk 301 is also rotatably connected with an end gear 310, the transmission gear 307 is meshed with the end gear 310, and the outer middle part of one group of transmission gears 307 is fixedly connected to the output end of the fourth drive motor 311, and the fourth drive motor 311 is fixedly installed at the inner bottom end of the rotating disk 301.

[0026] Those skilled in the art can understand that the storage mechanism 3 is used to store drill bits 110 of different specifications. Since the sliding plate 103 slides toward the end of the connecting rod 205 that is tilted downward, the drill bit 110 is likely to fall if it is not fixed. Therefore, the output end of the fourth drive motor 311 drives one group of transmission gears 307 to rotate, so that the end gear 310 rotates, and then all the transmission gears 307 and the first screw rod 305 rotate synchronously as a whole, so that the two first clamping members 309 connected to the same group of first screw rods 305 fix the drill bit 110; and by providing a placement groove 303, it is convenient for the user to place the drill bit 110.

[0027] Example 4 Please refer to Figure 3 As shown, the longitudinal adjustment mechanism 4 includes a second screw rod 401, a second guide rod 402 and a second stepper motor 403, the second screw rod 401 is rotatably connected to the inside of the second frame 105, the second guide rod 402 is fixedly connected to the inside of the second frame 105, the lifting plate 108 is threadedly connected to the outer surface of the second screw rod 401, the lifting plate 108 is slidably connected to the outer surface of the second guide rod 402, the top of the second screw rod 401 is fixedly connected to the output end of the second stepper motor 403, and the second stepper motor 403 is fixedly installed on the top of the second frame 105.

[0028] Please refer to Figure 3 As shown, a second drive motor 111 is fixedly installed on the top of the lifting plate 108, and a drive wheel 112 is fixedly connected to the output end of the second drive motor 111. A driven wheel 113 is fixedly installed on the top of the rotating member 109, and the drive wheel 112 is connected to the driven wheel 113 through a belt.

[0029] Those skilled in the art can understand that, the output end of the second stepper motor 403 drives the second screw rod 401 to rotate, so that the lifting plate 108 moves downward, driving the drill bit 110 to move downward; and the output end of the second drive motor 111 drives the drive wheel 112 to rotate, and the driven wheel 113 is rotated under the drive of the belt, thereby driving the rotating member 109, the fixing mechanism 6 and the drill bit 110 to rotate synchronously as a whole. As the drill bit 110 rotates and moves downward, it is possible to drill a hole in the skull.

[0030] Example 5 Please refer to Figure 4 As shown, a driven gear 114 is fixedly installed on the outer surface of the second frame 105, two groups of first driving gears 115 and a group of second driving gears 116 are rotatably connected to the bottom of the sliding plate 103, and a third driving motor 117 is also fixedly installed at the bottom of the sliding plate 103. The output end of the third driving motor 117 is fixedly connected to the second driving gear 116, and the two groups of first driving gears 115 are both meshed with the second driving gear 116, and the two groups of first driving gears 115 are also meshed with the driven gear 114, and a slot is opened on the driven gear 114 for the lifting plate 108 to pass through.

[0031] It can be understood by those skilled in the art that the second drive gear 116 is driven to rotate by the output end of the third drive motor 117, so that the two groups of first drive gears 115 rotate synchronously, thereby driving the driven gear 114 to rotate, so that the second frame 105 rotates. Since a slot is provided on the driven gear 114, two groups of first drive gears 115 are designed to ensure continuous rotation of the driven gear 114, making the design more ingenious.

[0032] Example 6 Please refer to Figure 6 As shown, the positioning mechanism 5 includes a rotating circle 501, which is rotatably connected to the inside of the mounting plate 104, and the inner circumference and outer circumference of the rotating circle 501 are respectively fixedly connected with a plurality of groups of inner teeth 502 and outer teeth 503, and the inside of the mounting plate 104 is rotatably connected with a plurality of groups of first gears 504 and a group of second gears 506.

[0033] Please refer to Figure 5 and Figure 6As shown, the inner teeth 502 are meshed with several groups of first gears 504, the outer teeth 503 are meshed with the second gears 506, the inner wall of the mounting plate 104 is fixedly mounted with a fifth drive motor 508, the output end of the fifth drive motor 508 is fixedly connected with the second gear 506, and the inner sliding connection of the rotating circle 501 is provided with several groups of second clamping members 505, the second clamping members 505 are fixedly connected with a tooth plate 507, and the tooth plate 507 is also meshed with the first gear 504.

[0034] Those skilled in the art can understand that, by driving the second gear 506 to rotate through the output end of the fifth drive motor 508, the outer teeth 503, the rotating circle 501 and the inner teeth 502 rotate as a whole, driving several groups of first gears 504 to rotate synchronously, so that several groups of second clamping members 505 move synchronously toward or away from the center of the mounting plate 104, and when approaching, the connecting rod 205 is clamped; and when moving away, the clamping is released.

[0035] Example 7 Please refer to Figure 8 As shown, the fixing mechanism 6 includes a third frame 601, which is welded to the bottom of the rotating member 109, and the inside of the third frame 601 is rotatably connected to the second screw 602, and the inside of the third frame 601 is fixedly connected to the second fixing rod 603, and two groups of third clamping members 605 are slidably connected to the second fixing rod 603, and the threads opened at both ends of the second screw 602 have opposite rotation directions, and the two groups of third clamping members 605 are respectively threadedly connected to the two ends of the outer surface of the second screw 602, and a servo motor 604 is arranged on the outside of the third frame 601, and one end of the second screw 602 is fixedly connected to the output end of the servo motor 604.

[0036] Those skilled in the art can understand that the second screw 602 is driven to rotate by the output end of the servo motor 604, so that the two groups of third clamping members 605 are close to or away from each other, and when they are close, the drill bit 110 is clamped, and when they are away, the drill bit 110 is released.

[0037] The working principle and use process of the device are as follows: First, the user twists the rotating wheel, and the base 1 is stuck and fixed on the two ends of the operating bed, and the device is fixed on the operating bed. The output end of the first stepper motor 204 drives the first screw rod 201 to rotate, so that the lifting seat 203 moves up and down. Since the first stepper motor 204 is provided on both sides, the heights of the lifting seats 203 on both sides can be inconsistent by controlling the output ends of the two groups of first stepper motors 204, so that the two groups of connecting rods 205 are in an inclined state, driving the sliding plate 103 to slide toward the lower part of the connecting rod 205, and when the sliding plate 103 slides to the matching position, the second gear 506 is driven to rotate by the output end of the fifth driving motor 508, so that the outer teeth 503, the rotating circle 501 and the inner teeth 502 rotate as a whole, driving several groups of first gears 504 to rotate synchronously, so that several groups of second clamping members 505 move synchronously toward the position close to the center of the mounting plate 104, so as to clamp the connecting rod 205, thereby fixing the lateral position of the drill bit 110; The output end of the second stepper motor 403 drives the second screw rod 401 to rotate, so that the lifting plate 108 moves downward, driving the drill bit 110 to move downward; the output end of the second drive motor 111 drives the driving wheel 112 to rotate, and under the drive of the belt, the driven wheel 113 rotates, thereby driving the rotating member 109, the fixing mechanism 6 and the drill bit 110 to rotate synchronously as a whole. Since the drill bit 110 rotates and moves downward, it can achieve drilling on the skull; It is worth mentioning here that if the size of the drill hole needs to be changed during the operation, it is rather troublesome to replace it manually. The present invention drives the second drive gear 116 to rotate through the output end of the third drive motor 117, so that the two groups of first drive gears 115 rotate synchronously, thereby driving the driven gear 114 to rotate, so that the second frame 105 rotates, so that the fixing mechanism 6 rotates to the top of the storage mechanism 3, and drives the rotating disk 301 to rotate through the output end of the first drive motor 107, so that the required drill bit 110 rotates to the bottom of the fixing mechanism 6, and drives the lifting plate 108 to move downward through the output end of the second stepper motor 403, so that the fixing mechanism 6 moves downward, and drives the second screw 602 to rotate through the output end of the servo motor 604, so that the two groups of third clamping members 605 are close to each other, and the drill bit 110 is clamped, so that the drill bit 110 is automatically replaced, meeting the needs of the staff.
