[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure.

[0033] An oral fixed implant guide, such as Figure 1-7 As shown, it includes a substrate body 100 and a tongue depressor body 200, a planting groove 110 is opened on the substrate body 100, the substrate body 100 and the tongue depressor body 200 are fixedly connected by a fixing assembly 300, a supporting assembly 400 is provided on the upper surface of the tongue depressor body 200, and a sliding assembly 500 is installed on the substrate body 100; an annular slide groove 510 is opened on both sides of the substrate body 100, and rollers 520 are installed in the two groups of annular slide grooves 510, and a rotating shaft 530 is penetrated at the center of the two groups of rollers 520, and a U-shaped fixing frame 540 is installed on the side of the two groups of rollers 520 away from the substrate body 100, and the upper and lower ends of the two groups of rotating shafts 530 are connected to the inner side of the corresponding U-shaped fixing frame 540 through bearings, and the top of the two groups of U-shaped fixing frames 540 Both are fixedly connected with a fixing block 550, and telescopic rods 560 are fixedly installed on opposite sides of the two groups of fixing blocks 550. The telescopic ends of the two pairs of telescopic rods 560 are fixedly connected with the same positioning ring 570. A second spring 580 is sleeved on the outside of each telescopic rod 560, and one end of the second spring 580 is fixedly connected to the fixing block 550, and the other end is fixedly connected to the positioning ring 570. The positioning ring 570 is located directly above the planting groove 110, and a ring notch is opened on one side of the positioning ring 570. A connecting block 590 is fixedly connected to the bottom of the U-shaped fixing frame 540 located on the outside of the substrate main body 100, and a bolt 5910 is penetrated through the side of the connecting block 590 away from the substrate main body 100, and a rubber block 5920 is fixedly connected to the side of the bolt 5910 close to the substrate main body 100.

[0034] The substrate body 100 is nearly semicircular and matches the curvature of the patient's gums. The substrate body 100 is made of resin material. The implantation groove 110 provided therein is engaged with normal teeth. The positioning ring 570 is moved to the top of the patient to be implanted through the provided sliding assembly 500. The staff pushes the positioning ring 570 to drive the two sets of U-shaped fixing frames 540 and the roller 520 fixed thereto to roll in the annular slide groove 510 on the inner and outer sides of the substrate body 100. It is worth noting that the second spring 580 is in a stretched state. Therefore, the tension of the second spring 580 is utilized to make the fixing block 550 and the U-shaped fixing frame 540 fixed thereto always generate an extrusion force in the direction close to the positioning ring 570, so that the roller 520 is tightly pressed against the annular slide groove 510 on the inner and outer sides of the substrate body 100. The groove 510, and since the arc shape of the substrate body 100 is designed to match the curvature of the patient's gums, its inner and outer arc shapes are not completely similar. By setting the telescopic rod 560, it is convenient to adjust the spacing between the fixed blocks 550 on both sides in real time when moving the positioning ring 570 to prevent the roller 520 from disengaging from the annular slide groove 510, and guide the drill bit to extend into the implant groove 110 of the substrate body 100 through the positioning ring 570, so as to ensure the accuracy of the drilling position and angle, and the ring notch facilitates the drill bit to enter the positioning ring 570 horizontally, reducing the patient's oral opening, making the surgical operation more convenient, and when the positioning ring 570 moves to the place to be drilled, tighten the bolt 5910 so that the rubber block 5920 is tightly against the outside of the substrate body 100 to fix the positioning ring 570 for subsequent surgical operations.

[0035] Please refer to Figure 1-4 As shown, the fixing assembly 300 includes a fixing plug 310 fixedly connected to the center of the inner side of the substrate body 100, and the fixing plug 310 is provided with plug holes 320 on both sides. The tongue depressor body 200 is fixedly connected to a fixing seat 330 at the center of one side close to the substrate body 100, and the fixing seat 330 is provided with a slot 340 matching the fixing plug 310 on the side away from the tongue depressor body 200. The fixing seat 330 is fixedly connected to both sides of the fixing sleeve 350. The two sets of fixing sleeves 350 are fixedly connected to the fixing plug 310. 0, one end of each of the two ends of the rod 360 is penetrated by an insertion rod 360 that matches the socket 320, one end of the rod 360 extends into the slot 340 and is plugged into the socket 320, the outer wall of the rod 360 is located at the bottom of the inner cavity of the fixed sleeve 350 and is fixedly sleeved with a fixing ring 370, a first spring 380 is fixedly connected between the fixing ring 370 and the top of the inner cavity of the fixed sleeve 350, the first spring 380 is sleeved on the outside of the rod 360, and a pull handle 390 is fixedly connected to the end of the rod 360 away from the slot 340.

[0036] By pulling the pull handle 390, the insertion rod 360 is driven to disengage from the insertion hole 320 on the fixed plug block 310. At this time, the insertion rod 360 drives the fixing ring 370 to squeeze the first spring 380, and the first spring 380 is in a compressed state, thereby releasing the fixation of the substrate body 100 and the tongue depressor body 200, and the substrate body 100 can be removed and replaced. After the replacement is completed, the fixing plug block 310 on one side of the new substrate body 100 is inserted into the slot 340 of the fixing seat 330, and then the pull handle 390 is released, and the elastic force of the first spring 380 itself is used to push the fixing ring 370 and the insertion rod 360 fixed thereto to be reinserted into the insertion hole 320 on the fixing plug block 310, thereby completing the fixation of the substrate body 100 and the tongue depressor body 200. The fixing assembly 300 is convenient for replacing different types of substrate bodies 100, and it is also convenient for cleaning and maintenance of the substrate body 100, so that the substrate body 100 can be reused.

[0037] Please refer to Figure 1 and Figure 5 As shown, the support assembly 400 includes two groups of bases 410 fixedly installed on one side of the upper surface of the tongue depressor body 200, and a support column 420 is rotatably connected between the two groups of bases 410 through a rotating shaft. A first slide groove 430 is provided on one side of the support column 420, and a first slider 440 is slidably connected in the first slide groove 430. The first slider 440 is fixedly connected to an adjustment support rod 450 on the side away from the first slide groove 430. A second slide groove 460 is provided on the upper surface of the tongue depressor body 200, and a receiving cavity is provided at one end of the second slide groove 460 close to the two groups of bases 410 , and a micro motor 470 is fixedly installed in the accommodating cavity, and the output end of the micro motor 470 is fixedly connected with a threaded screw 480 through a coupling, and the other end of the threaded screw 480 is connected to the side of the second slide groove 460 away from the micro motor 470 through a bearing, and the outer side of the threaded screw 480 is threadedly connected with a second slider 490 matching the second slide groove 460, and two groups of mounting seats 4910 are fixedly installed on the top of the second slider 490, and the end of the adjusting support rod 450 away from the first slider 440 is rotatably connected between the two groups of mounting seats 4910 through a rotating shaft.

[0038] By starting the micro motor 470, the output end of the micro motor 470 drives the threaded screw 480 to rotate, and the rotation of the threaded screw 480 drives the second slider 490 threadedly connected thereto to start sliding in the second slide groove 460, so that one end of the adjustment support rod 450 rotates around the two groups of mounting seats 4910 on the top of the second slider 490, and the first slider 440 fixed at the other end of the adjustment support rod 450 slides in the first slide groove 430 on the support column 420, so that the angle of the support plate 421 can be adjusted, and the patient's mouth can be supported by the support plate 421 conveniently, without manual adjustment, and has good adaptability. The patient's oral opening degree can also be adjusted step by step, and the adjustment ability is strong. At the same time, the patient can also maintain the mouth opening degree for a long time, and the controllability is strong. Since the tongue depressor body 200 and the support assembly 400 are integrally connected, it has good comfort and strong stability, which is beneficial to the patient's tooth implant work.

[0039] Please refer to Figure 6 As shown, sliding grooves 431 are opened on both sides of the first sliding groove 430 , and balls 441 matching the sliding grooves 431 are installed on both sides of the first sliding block 440 , and the balls 441 are slidably connected to the sliding grooves 431 .

[0040] By providing the ball bearing 441 and the sliding groove 431 , the friction between the first sliding block 440 and the first sliding groove 430 is reduced, so that the first sliding block 440 slides more smoothly in the first sliding groove 430 .

[0041] Please refer to Figure 1 As shown, a support plate 421 is fixedly installed on the top of the support column 420 , and a buffer pad 422 is wrapped around the outside of the support plate 421 .

[0042] By providing the buffer pad 422 to be in direct contact with the inside of the oral cavity, the buffering capacity of the contact point is improved and the damage to the roof of the oral cavity is reduced.

[0043] When in use, the positioning ring 570 is moved to the top of the patient to be implanted through the provided sliding component 500, and the staff pushes the positioning ring 570 to drive the two sets of U-shaped fixing frames 540 and the roller 520 fixed thereto to roll in the annular groove 510 on the inner and outer sides of the base body 100. It is worth noting that the second spring 580 is in a stretched state, so the tension of the second spring 580 is used to make the fixing block 550 and the U-shaped fixing frame 540 fixed thereto always generate an extrusion force in the direction close to the positioning ring 570, so that the roller 520 is tightly against the annular groove 510 on the inner and outer sides of the base body 100, and because the base body 100 is designed with an arc shape that matches the curvature of the patient's gums, its inner and outer arc shapes are not completely the same. Similarly, by setting a telescopic rod 560, when moving the positioning ring 570, the fixed blocks 550 on both sides can adjust the spacing in real time to prevent the roller 520 from disengaging from the annular groove 510, and guide the drill bit to extend into the planting groove 110 of the substrate body 100 through the positioning ring 570, thereby ensuring the accuracy of the drilling position and angle, and the drill bit can enter the positioning ring 570 laterally through the ring notch, reducing the patient's oral opening and making the surgical operation more convenient. When the positioning ring 570 moves to the place where the hole is to be drilled, tighten the bolt 5910 so that the rubber block 5920 is tightly against the outside of the substrate body 100, fixing the positioning ring 570, and facilitating subsequent surgical operations. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
