[0025] When performing oral implants on patients, due to the pain of oral implants, the patients will subconsciously close their mouths. In the process of using the connecting disk 401 to position and guide the implants, it is easy for the positioning disk 308 to be offset, thereby affecting the use of the positioning disk 308. Therefore, as a preferred technical solution of this embodiment, a base is clamped on the top surface of the front end fixing part 1, and a bite piece is fixedly installed on the base, and a silicone layer is provided on the bite piece.
[0026] In the above technical solution, the bite piece is used so that the patient can bite on the bite piece during the biting process, thereby ensuring that a certain gap is left when the patient is in the biting state, thereby avoiding the deviation of the positioning plate 308 caused by the patient's complete biting; and the silicone layer is used to achieve the effect of buffering the teeth.
[0027] When performing oral implants on different patients, since the implantation sites of each patient are different, it is necessary to make corresponding adjustments to the position of the connecting plate 401 before performing oral implants on different patients. Therefore, as a preferred technical solution of this embodiment, a positioning nut 303 is threadedly connected on the circumferential surface of the sliding sleeve 301, and the positioning nut 303 abuts against the surface of the rear end extension portion 2.
[0028] Furthermore, a protrusion 302 is fixedly mounted on the circumferential surface of the sliding sleeve 301 , and the protrusion 302 is slidably disposed in the rear end extension portion 2 .
[0029] In the above technical solution, by utilizing the sliding sleeve 301 on the rear end extension portion 2, the sliding sleeve 301 is made to slide along the rear end extension portion 2, thereby achieving the effect of adjusting the position of the connecting disk 401 on the sliding sleeve 301. After the connecting disk 401 on the sliding sleeve 301 is adjusted to an appropriate position, the positioning nut 303 on the sliding sleeve 301 is rotated so that the positioning nut 303 abuts against the surface of the rear end extension portion 2, thereby achieving the effect of limiting the sliding of the sliding sleeve 301, and further achieving the effect of locking the adjusted position of the connecting disk 401.
[0030] When performing oral implants at different positions, due to the different oral structures, in order to keep the implanted teeth always vertical to the jawbone, after adjusting the position of the connecting plate 401, the inclination angle of the connecting plate 401 also needs to be adjusted accordingly. Therefore, as the preferred technical solution of this embodiment, a rotating rod 304 is axially slidably arranged inside the sliding sleeve 301, a connecting rod 305 is fixedly installed at one end of the rotating rod 304, a plurality of first springs 306 are arranged between the connecting rod 305 and the sliding sleeve 301, and a plurality of positioning pins 307 are fixedly installed on the connecting rod 305; a positioning plate 308 is sleeved on the circumferential surface of the sliding sleeve 301, the positioning plate 308 is slidably arranged on the rear end extension portion 2, and a plurality of pin grooves matching the connecting rod 305 are arranged on the side of the positioning plate 308 close to the connecting rod 305, and a plurality of pin grooves are arranged in a circular array on the positioning plate 308.
[0031] Furthermore, a rotating ring 309 is sleeved on the circumferential surface of the sliding sleeve 301 , and two ends of the first spring 306 are fixedly mounted on the connecting rod 305 and the rotating ring 309 , respectively.

At this time, the first spring 306 is in a compressed state, and at this time, the pulled-out rotating rod 304 is rotated, so that the sliding sleeve 301 can be driven to rotate, thereby The effect of being able to rotate the inclination angle of the connecting disk 401 by rotating the sliding sleeve 301, and after the connecting disk 401 is rotated to the appropriate position, by utilizing the elastic force of the first spring 306, the positioning pin 307 on the connecting rod 305 can slide toward the positioning disk 308 under the action of the elastic force of the first spring 306, so that the multiple positioning pins 307 on the connecting rod 305 can be inserted into the corresponding pin grooves provided on the positioning disk 308, thereby achieving the effect of being able to lock the position of the connecting disk 401 after rotation.
[0033] As a preferred technical solution of this embodiment, a plurality of first guide grooves 4041 are provided on the rotating disk 404, and support rods 402 are slidably arranged inside the plurality of first guide grooves 4041, and the bottom ends of the support rods 402 are fixedly mounted on the connecting disk 401, and a fixed disk 403 is fixedly mounted on the top end of the support rods 402, and a plurality of guide members 405 are radially slidably arranged on the fixed disk 403.
[0034] In the above technical solution, by utilizing the multiple first guide grooves 4041 on the rotating disk 404, during the process of rotating the rotating disk 404 on the connecting disk 401, the guide rods in the multiple first guide grooves 4041 can slide along the first guide grooves 4041, thereby achieving the effect of guiding the rotation of the rotating disk 404.
[0035] As a preferred technical solution of this embodiment, multiple guide seats 4011 are fixedly installed on the connecting disk 401, and slide grooves 4012 are opened on the top surfaces of the multiple guide seats 4011. Slide rods are slidably arranged inside the slide grooves 4012, and the slide rods are fixedly installed on the bottom surface of the rotating disk 404.
[0036] In the above technical solution, by utilizing the multiple slide grooves 4012 on the connecting disk 401, the multiple slide bars on the bottom surface of the rotating disk 404 can slide along the multiple slide grooves 4012 respectively, thereby achieving the effect of further guiding the rotation of the rotating disk 404.
[0037] As a preferred technical solution of this embodiment, the guide member 405 includes a slide rail 4051 fixedly installed on the bottom surface of the fixed disk 403, a sliding portion 4052 is slidably arranged on the slide rail 4051, one end of the sliding portion 4052 is fixedly connected to a connecting portion 4054, and a fixing rod 4055 is fixedly installed on the connecting portion 4054; a through hole 4043 is provided on the rotating disk 404, and a plurality of fixing rods 4055 are partially slidably arranged in the through hole 4043.
[0038] Furthermore, a plurality of second guide grooves 4042 are formed on the rotating disk 404 , and guide blocks 4053 are fixedly installed inside the second guide grooves 4042 . The guide blocks 4053 are fixedly installed on the bottom surface of the sliding portion 4052 .
[0039] In the above technical solution, by rotating the rotating disk 404 on the connecting disk 401, the multiple sliding blocks 407 can slide along the multiple second guide grooves 4042 respectively, and then by adjusting the position of the sliding block 407, it can drive the sliding part 4052 to slide along the slide rail 4051, and then it can make the multiple fixed rods 4055 slide along the radial direction of the fixed disk 403. By adjusting the positions of the multiple fixed rods 4055, the size of the gap between the multiple fixed rods 4055 can be adjusted, and then according to the process of oral implantation, the multiple fixed rods 4055 can be used to position and guide drill bits of different specifications.
[0040] In the process of using multiple guide members 405 to position and guide drill bits of different specifications, due to the friction between the drill bit and the fixed rod 4055, the drill bit is easily worn during high-speed rotation. Therefore, as a preferred technical solution of this embodiment, a rotating sleeve 4056 is sleeved on the circumferential surface of the multiple fixed rods 4055, and the bottom end of the rotating sleeve 4056 is rotatably connected to the connecting part 4054.
[0041] In the above technical solution, by utilizing the rotating sleeve 4056 on the fixed rod 4055, the rotating sleeve 4056 can rotate along with the drill bit during high-speed rotation of the drill bit, thereby reducing the friction between the drill bit and the fixed rod 4055, thereby minimizing the wear of the drill bit due to the large friction.
[0042] After the rotating disk 404 on the rotating connecting disk 401 adjusts the gap size between the multiple fixed rods 4055, due to the high-speed rotation of the drill bit, it is easy to cause the rotating disk 404 to rotate, thereby causing the gap size between the multiple fixed rods 4055 to change. Therefore, as a preferred technical solution of this embodiment, a dial plate 406 is fixedly installed on the side of the rotating disk 404, a sliding block 407 is slidably arranged on the dial plate 406, a second spring 408 is arranged between the sliding block 407 and the dial plate 406, and a clamping block 409 is fixedly installed on the bottom surface of the sliding block 407; a plurality of clamping grooves 4013 matching the clamping block 409 are opened on the side of one of the guide seats 4011.
[0043] In the above technical solution, when it is necessary to adjust the gap size between the multiple fixed rods 4055, the sliding block 407 on the dial plate 406 is moved so that the sliding block 407 can be moved away from the guide seat 4011. At this time, the second spring 408 will be in a compressed state, and the dial plate 406 on the rotating disk 404 is driven to rotate the rotating disk 404 on the connecting disk 401. When the multiple fixed rods 4055 are adjusted to a suitable gap size under the rotation of the rotating disk 404, the slider on the dial plate 406 is used to make the block 409 on the slider be inserted into the corresponding slot 4013 on the guide seat 4011 under the action of the elastic force of the second spring 408, thereby limiting the rotation of the rotating disk 404 and avoiding as much as possible the situation that the high-speed rotation of the drill bit easily causes the rotation of the rotating disk 404, thereby causing the gap size between the multiple fixed rods 4055 to change, thereby affecting the positioning and guiding of the drill bit.
[0044] As a preferred technical solution of this embodiment, a pointer 410 is fixedly mounted on the top surface of the dial plate 406 , and a scale line 411 matching the pointer 410 is arranged on the top surface of the fixed disk 403 .
[0045] In the above technical solution, by utilizing the pointer 410 on the dial plate 406 and the scale line 411 on the fixed disk 403, the rotation angle of the rotating disk 404 can be displayed, thereby facilitating intuitive adjustment of the gap size between the multiple fixed rods 4055.
[0046] Working principle: before use, the entire device is sleeved on the teeth by using the front end fixing part 1, and the sliding sleeve 301 on the rear end extension part 2 is used to make the sliding sleeve 301 slide along the rear end extension part 2, so as to adjust the position of the connecting disk 401 on the sliding sleeve 301. After the connecting disk 401 on the sliding sleeve 301 is adjusted to an appropriate position, the positioning nut 303 on the sliding sleeve 301 is rotated so that the positioning nut 303 abuts against the surface of the rear end extension part 2, thereby limiting the sliding of the sliding sleeve 301, and further locking the adjusted position of the connecting disk 401. When the inclination angle of the connecting disk 401 needs to be adjusted, the rotating rod 304 on the sliding sleeve 301 is pulled so that the rotating rod 304 can slide along the axial direction of the sliding sleeve 301 in a direction away from the connecting disk 401, so that the multiple positioning pins 305 on the connecting rod 305 are moved. 7 can slide in the direction away from the positioning disk 308. At this time, the first spring 306 is in a compressed state. At this time, by rotating the pulled-out rotating rod 304, the sliding sleeve 301 can be driven to rotate, and then the inclination angle of the connecting disk 401 can be rotated by rotating the sliding sleeve 301. After the connecting disk 401 is rotated to an appropriate position, the elastic force of the first spring 306 is utilized, so that the positioning pin 307 on the connecting rod 305 can slide in the direction close to the positioning disk 308 under the action of the elastic force of the first spring 306, so that the multiple positioning pins 307 on the connecting rod 305 can be inserted into the corresponding pin grooves provided on the positioning disk 308, thereby achieving the effect of locking the position of the connecting disk 401 after rotation; therefore, by utilizing the adjustment component 3 on the rear end extension portion 2, the planting position and planting angle can be adjusted according to different planting positions.
[0047] When the gap between the plurality of fixing rods 4055 needs to be adjusted, the sliding block 407 on the dial plate 406 is moved so that the sliding block 407 can move away from the guide seat 4011. At this time, the second spring 408 will be in a compressed state, and then the rotating disk 404 on the connecting disk 401 is rotated so that the plurality of sliding blocks 407 can slide along the plurality of second guide grooves 4042 respectively, thereby making it possible to drive the sliding part 4052 to slide along the slide rail 4051 by adjusting the position of the sliding block 407, thereby making it possible to make the plurality of fixing rods 4055 slide along the radial direction of the fixing disk 403. 055, thereby achieving the effect of being able to position and guide drill bits of different specifications according to the process of oral implantation, and when the multiple fixing rods 4055 are adjusted to a suitable gap size under the rotation of the rotating disk 404, by utilizing the slider on the dial plate 406, the block 409 on the slider can be inserted into the corresponding slot 4013 on the guide seat 4011 under the action of the elastic force of the second spring 408, thereby achieving the effect of limiting the rotation of the rotating disk 404, and avoiding as much as possible the high-speed rotation of the drill bit, which easily causes the rotation of the rotating disk 404, thereby causing the gap size between the multiple fixing rods 4055 to change, thereby affecting the positioning and guiding of the drill bit.
[0048] Furthermore, by utilizing the rotating sleeve 4056 on the fixed rod 4055, the rotating sleeve 4056 can rotate along with the drill bit during high-speed rotation of the drill bit, thereby reducing the friction between the drill bit and the fixed rod 4055, thereby minimizing wear on the drill bit due to high friction.
[0049] Therefore, by utilizing the positioning component 4, it is possible to position and guide implant drill bits of different sizes according to the implantation process.
