It includes two parts of lower supporting implant and upper dental restoration. It uses artificial materials (such as metal, ceramic, etc.) to make implant (generally similar to the shape of tooth root), which is implanted into tissue (usually maxilla and mandible) by surgical method and obtains firm retention support of bone tissue, and connects the upper dental restoration through special device and method. Dental implant can obtain repair effect similar to natural tooth function, structure and aesthetic effect, and has become the first choice for more and more edentulous patients.

[0004] In order to ensure the accurate position of the implant implanted into the jaw bone, therefore, the implant point needs to be accurately positioned before implantation. The prior art uses an implant positioning ruler to position the implant position. When positioning, the implant positioning ruler needs to be inserted into the adjacent two adjacent teeth between the implant area, then the distance between the two adjacent teeth is read according to the scale on the implant positioning ruler, and the middle position between the two adjacent teeth is calculated as the positioning position according to the distance. The foregoing method cannot intuitively and accurately indicate the middle position of the implant area to the medical staff, so the operation is not convenient, the positioning accuracy is poor, and the dental implant is prone to failure.

[0051] Embodiment 1:

[0052] AsFigures 1 to 3 As shown, an embodiment of the present invention discloses a pulley-driven oral implant positioner, which is used to locate the implant point of an implant that needs to be implanted in an edentulous area (an area to be implanted 90) into the jawbone. The teeth adjacent to the area to be implanted 90 are referred to herein as adjacent teeth 91 of the area to be implanted 90. The oral implant of this embodiment mainly includes a first positioning member 10, a second positioning member 20, a third positioning member 30 and a pulley transmission mechanism.

[0053] like Figure 2 As shown, the first positioning member 10 is used to abut against one of the two adjacent teeth 91 in the area to be implanted 90; the second positioning member 20 is movably connected to the first positioning member 10, and the second positioning member 20 is used to abut against the other adjacent tooth 91 in the area to be implanted 90; the third positioning member 30 is used to locate the position of the implantation point, and the third positioning member 30 is movably connected to the first positioning member 10; when locating the implantation point, the first positioning member 10 and the second positioning member 20 are respectively pressed against the adjacent teeth 91 on both sides of the area to be implanted 90 by moving the second positioning member 20 relative to the first positioning member 10. The third positioning member 30 for locating the implantation point also slides to the position of the implantation point by moving relative to the first positioning member 10;

[0054] The pulley transmission mechanism is used to form a movable connection between the second positioning member 20 and the first positioning member 10, and between the third positioning member 30 and the first positioning member 10; that is, the second positioning member 20 and the first positioning member 10 are movablely connected via the pulley transmission mechanism, and the first positioning member 10 and the third positioning member 30 are movablely connected via the pulley transmission mechanism. Driven by the pulley 41 mechanism, the second positioning member 20 can move relative to the first positioning member 10, and the third positioning member 30 can also move relative to the first positioning member 10.

[0055] The pulley transmission mechanism is also used to drive the third positioning member 30 to slide synchronously with the second positioning member 20, and the sliding distance of the third positioning member 30 relative to the first positioning member 10 is half of the sliding distance of the second positioning member 20 relative to the first positioning member 10.

[0056] like Figures 1 to 2As shown, when the position of the implant site needs to be positioned, the pulley transmission mechanism plays two roles, on the one hand, it drives the second positioning member 20 to slide relative to the first positioning member 10, so that the first positioning member 10 and the second positioning member 20 are respectively in abutment with the two adjacent teeth 91, on the other hand, it drives the third positioning member 30 to move synchronously with the second positioning member 20, that is, when the second positioning member 20 moves, the third positioning member 30 also moves, and when the second positioning member 20 stops moving, the third positioning member 30 also stops moving. And through the transmission matching of the pulley 41 mechanism, the distance moved by the third positioning member 30 is always half of the distance moved by the second positioning member 20. In this way, no matter how far the distance between the two adjacent teeth 91 on both sides of the implant area 90 is, when the first positioning member 10 and the second positioning member 20 are respectively in abutment with the two adjacent teeth 91, the third positioning member can accurately move to the center position between the first positioning member 10 and the second positioning member 20, which is also the center position between the two adjacent teeth 91, that is, the position of the implant site.

[0057] As shown in Figure 12 , the third positioning member 30 is provided with a circular positioning ring 32 at one end away from the fixed member 50, as shown in Figure 7 , the first positioning member 10 is provided with a semicircular first clasp 11 at one end away from the fixed member 50, as shown in Figure 10 , the second positioning member 20 is provided with a semicircular second clasp 21 at one end away from the fixed member 50, when the first positioning member 10, the second positioning member 20 and the third positioning member 30 are spliced together, the third positioning member 30 is located between the first positioning member 10 and the second positioning member 20, and the first clasp 11 and the second clasp 21 are spliced into a complete circular ring, the positioning ring 32 is located in the spliced circular ring, and the center of the positioning ring 32 coincides with the center of the spliced circular ring. When the first positioning member 10 is located at a position where the outer side of the first clasp 11 abuts against one adjacent tooth 91 of the implant area 90, and the second positioning ring 32 is located at a position where the outer side of the second clasp 21 abuts against the other adjacent tooth 91 of the implant area 90, the center of the positioning ring 32 of the third positioning member 30 is accurately located at the middle position of the implant area 90.

[0058] As shown in Figures 4 to 7 , in this embodiment, the pulley transmission oral implant positioning device further comprises a fixed member 50, which is used to install and fix other components of the pulley transmission oral implant positioning device, and the fixed member 50 is provided with a hollow cavity, wherein the fixed member 50 is relatively stationary during the implant positioning process. In this embodiment, the first positioning member 10 can also be directly provided on the fixed member 50, so that the first positioning member 10 and the fixed member 50 become an integral whole, and at this time the first positioning member 10 serves as a part of the fixed member 50. As shown in Figures 1 to 3As shown, the pulley transmission mechanism realizing the aforementioned transmission mode comprises a pulley 41, a flexible connecting member 42 and a movable member 43, the movable member 43 is in sliding connection with the fixed member 50, the pulley 41 is connected with the third positioning member 30, the first positioning member 10 is arranged at one end of the fixed member 50, the second positioning member 20 is arranged at one end of the movable member 43, one end of the flexible connecting member 42 is connected with the movable member 43, and the opposite end extends to the position of the pulley 41 along the first direction and is bent along the surface of the pulley 41 to the second direction and then is connected with the fixed member 50, the first direction and the second direction are opposite directions. The flexible connecting member 42 can be made of steel wire, rope, long strip or belt-shaped member made of material with certain flexibility and can be bent along the surface of the pulley 41. In the embodiment, the third positioning member 30 can also be directly arranged on the movable member 43, so that the third positioning member 30 and the movable member 43 become an integral whole, and the third positioning member 30 serves as a part of the movable member 43.

[0059] In the embodiment, one end of the flexible connecting member 42 is connected with the fixed member 50, and the opposite end is connected with the movable member 43. A part of the flexible connecting member 42 between the two ends thereof is wound around the surface of the pulley 41, and the length of the flexible connecting member 42 wound around the pulley 41 is the length of a semicircle, so that the flexible connecting member 42 can extend from the position connected with the movable member 43 to the direction away from the movable member 43, then is wound around the surface of the pulley 41 until it is bent by 180 degrees and then extends to the direction close to the movable member 43 and is fixed with the fixed member 50. In order to facilitate the connection of the end of the flexible connecting member 42 away from the movable member 43 with the fixed member 50, a connecting member extending from the inner wall of the fixed member 50 to a certain position in the direction perpendicular to the moving direction of the pulley 41 is arranged on the fixed member 50, a pull ring 54 is arranged at the free end of the connecting member, and one end of the flexible connecting member 42 is connected with the pull ring 54 away from the connecting member.

[0060] In this way, the fixed member 50, the flexible connecting member 42, the pulley 41 and the movable member 43 form a movable pulley 41 system. Since the second positioning member 20 is arranged at one end of the movable member 43 and moves synchronously with the movable member 43, the first positioning member 10 keeps the position fixed through the fixed member 50, when the movable member 43 moves to drive the second positioning member 20 and the flexible connecting member 42 to move, the flexible connecting member 42 drives the pulley 41 to move synchronously with the second positioning member 20, and the moving speed of the pulley 41 is always half of that of the second positioning member 20, and since the third positioning member 30 is connected with the pulley 41, the position of the third positioning member 30 is always in the middle position between the first positioning member 10 and the second positioning member 20 during the movement.

[0061] In order to facilitate the medical staff to operate the pulley transmission oral implant positioning device, the first positioning member 10 and the second positioning member 20 are accurately abutted with the two adjacent teeth 91, the pulley transmission oral implant positioning device further comprises an adjusting member 60, which is arranged at the end of the fixing member 50 away from the first positioning member 10, and the adjusting member 60 is connected with the movable member 43, and the adjusting member 60 is used to drive the movable member 43 to slide relative to the fixing member 50.

[0062] In the embodiment, the fixing member 50 is divided into two opposite ends, one end is used as a working end and is provided with the first positioning member 10, the second positioning member 20 and the third positioning member 30, and the other end is used as an operating end and is provided with the adjusting member 60. The working end is inserted into the patient's mouth during positioning, and the operating end can be located away from the patient's mouth and exposed outside the patient's mouth. Therefore, when the medical staff uses the pulley transmission oral implant positioning device to position the implant position 92, the medical staff can operate away from the patient's mouth, and the patient's mouth or face does not block the operation, thereby improving the convenience and accuracy of the operation. The medical staff can drive the movable member 43 to move by operating the adjusting member 60 at the far end, and the movable member 43 drives the second positioning member 20 to move and synchronously drives the third positioning member 30 to move through the pulley transmission mechanism, so that the implant position 92 can be quickly and conveniently positioned.

[0063] As shown in Figures 1 to 3 and Figure 13 , as one of the embodiments, an inner thread matched with the threaded rod 62 is arranged at the end of the fixing member 50 away from the first positioning member 10. When the medical staff rotates the adjusting end 61, the threaded rod 62 rotates with the adjusting end 61. Under the action of the inner thread matched with the threaded rod 62 on the fixing member 50, the threaded rod 62 moves relative to the fixing member 50 while rotating with the adjusting end 61, thereby driving the movable member 43 to move.

[0064] As another embodiment, an intermediate connecting member 63 is arranged, which is detachably connected with the end of the fixing member 50 away from the first positioning member 10. The intermediate connecting member 63 is provided with a threaded hole, which is threadedly connected with the threaded rod 62. When the medical staff rotates the adjusting end 61, the threaded rod 62 rotates with the adjusting end 61. Under the action of the thread matched with the threaded rod 62 in the threaded hole, the threaded rod 62 moves relative to the fixing member 50 while rotating with the adjusting end 61, thereby driving the movable member 43 to move. The intermediate connecting member 63 is connected with the fixing member 50 through the thread.

[0065] As shown in Figure 13As shown, in order to make the movable member 43 and the adjusting member 60 detachably connected, the embodiment can be provided with a connecting protrusion 621 at the end of the threaded rod 62 away from the adjusting end 61, and a clamping groove 431 with an opening at the end of the movable member 43 away from the first positioning member 10, and the connecting protrusion 621 is inserted into the clamping groove 431 from the opening of the clamping groove 431 to achieve the detachable connection of the adjusting member 60 and the movable member 43.

[0066] As another implementation method, the adjusting member 60 includes an adjusting end 61 for rotation operation by medical staff and a threaded rod 62 connected with the adjusting end 61 and capable of synchronous rotation with the adjusting end 61, and the outer surface of the threaded rod 62 is provided with threads. The end of the threaded rod 62 opposite to the adjusting end 61 is connected with the movable member 43.

[0067] As one of the implementation methods, the end of the fixed member 50 away from the first positioning member 10 can be provided with an internal thread matched with the threads of the threaded rod 62 for use. When the medical staff rotates the adjusting end 61, the threaded rod 62 rotates with the adjusting end 61. Under the action of the internal thread matched with the threaded rod 62 on the fixed member 50, the threaded rod 62 moves relative to the fixed member 50 while rotating with the adjusting end 61, thereby driving the movable member 43 to move.

[0068] As a preferred method, in the embodiment, the pulley-driven oral implant positioning device further comprises a first guide mechanism for limiting the movable member 43 to slide in a straight line relative to the first positioning member 10.

[0069] The embodiment restricts the movement direction of the movable member 43 by providing the first guide mechanism, so that the movable member 43 can drive the second positioning member 20 to move in a straight line, thereby ensuring the accurate measurement of the distance between the two adjacent teeth 91 in the implant area.

[0070] As shown, Figures 4 to 10 The first guide mechanism includes a first sliding track 51 provided on the fixed member 50 and a sliding groove 432 provided on the movable member 43 and matched with the first sliding track 51.

[0071] In addition, as a preferred implementation method, the pulley-driven oral implant positioning device further comprises a second guide mechanism for limiting the third positioning member 30 to slide in a straight line relative to the first positioning member 10.

[0072] The embodiment restricts the movement direction of the third positioning member 30 by providing the second guide mechanism, so that the third positioning member 30 can move in a straight line, thereby ensuring that the third positioning member 30 accurately moves to the position between the first positioning member 10 and the second positioning member 20.

[0073] The second guiding mechanism comprises a second sliding track 52 arranged on the fixing member 50 and a first limiting block 33 arranged on the third positioning member 30 and matched with the second sliding track 52.

[0074] As a preferred embodiment, the guiding direction of the first guiding mechanism is the same as that of the second guiding mechanism, so that the third positioning member 30 and the second positioning member 20 can move synchronously in the same direction to improve the positioning accuracy.

[0075] In other embodiments, the first guiding mechanism and the second guiding mechanism can also be sliding tracks and sliding blocks, guide rods and guide sleeves, guide grooves and sliding blocks, etc., which are not limited here.

[0076] As shown in Figures 1 to 3 In addition, the embodiment can further comprise a first elastic member 71 connected at one end to the fixing member 50 and at the opposite end to the pulley 41 or the third positioning member 30 on the basis of the foregoing structure.

[0077] The first elastic member 71 can be a spring, which is stretched when the movable member 43 drives the pulley 41 to move away from the first positioning member 10, and generates a restoring force to move the pulley 41 towards the first positioning member 10. The combination of the first elastic member 71 and the adjusting member 60 can realize the back-and-forth movement of the pulley 41, so as to accurately and conveniently adjust the moving positions of the second positioning member 20 and the third positioning member 30.

[0078] As shown in Figure 5 and Figure 20 In the embodiment, the fixing member 50 further comprises a position marker 53 for measuring the moving positions of the second positioning member 20 and / or the third positioning member 30.

[0079] The position marker 53 can be a scale indicating the distance and corresponding numbers arranged on the surface of the positioning member. The position of the first positioning member 10 is taken as the 0 scale position. Thus, according to the scale of the positions of the second positioning member 20 and the third positioning member 30, the distance between the two adjacent teeth 91 of the region 90 to be planted and the position of the planting point along the length direction of the fixing member 50 can be conveniently obtained.

[0080] When the position marker 53 is used, the pulley-driven oral implant positioning device in the embodiment can also be used in another way, i.e., the first positioning member 10 is first brought into abutment with one adjacent tooth, and then the third positioning member 30 is moved to a position at a preset distance from the first positioning member 10. The distance moved by the third positioning member 30 can be determined according to the distance moved by the second positioning member 20. This use is for the case of implanting at a position at a specific distance from one adjacent tooth.

[0081] Embodiment 2

[0082] The prior art implant positioning tool is removed after positioning, and then a dotting method is used to dot on the alveolar bone of the implant area 90 according to the previously positioned position. However, since the positioning tool is not used during dotting, it is difficult to ensure the accuracy of the dotting position.

[0083] The pulley-driven oral implant positioning device of the present embodiment adds a positioning and dotting device 80 to the positioning device of the previous embodiment, which is used to dot at the implant position positioned by the third positioning member 30.

[0084] The positioning and dotting device 80 is arranged at the positioning end of the third positioning member 30, and after the third positioning member 30 is moved to the positioning position, the medical staff can directly operate the positioning and dotting device 80 to dot at the positioned implant position. During dotting, the third positioning member 30 does not need to be removed from the oral cavity, and the third positioning member 30 is always located at the positioning position, so that the positioning and dotting device 80 can accurately dot at the positioning position of the third positioning member 30 with the assistance of the third positioning member 30.

[0085] As shown in Figure 14 As a preferred implementation, the positioning and dotting device 80 in the present embodiment includes a pressing member 81, an intermediate transmission mechanism, and a dotting member 82. The pressing member 81 is arranged on the fixing member 50, the dotting member 82 is arranged at the end of the third positioning member 30 for positioning, one end of the intermediate transmission mechanism is connected with the pressing member 81, and the opposite end abuts against the dotting member 82. The pressing member 81 is used to move the dotting member 82 in the dotting direction through the intermediate transmission mechanism after being pressed.

[0086] When the third positioning member 30 is moved to the middle position of the implant area 90, the medical staff can press the pressing member 81. After the pressing member is pressed, the intermediate transmission mechanism is actuated, and the intermediate transmission mechanism moves the dotting member 82 in the dotting direction to penetrate into the gum or alveolar bone of the implant position 92.

[0087] As shown in Figures 14 to 17As shown, specifically, the intermediate transmission mechanism includes a transmission member 83, a second elastic member 84, and a limiting step 85 for limiting the position of the marking member 82 along the marking direction, and the second elastic member 84 is used to apply an elastic force to the marking member 82 along the marking direction towards the alveolar bone. The pressing member 81 drives the marking member 82 to move out of the limiting step 85 by pressing the transmission member 83, so that the marking member 82 is driven by the elastic force of the second elastic member 84 to penetrate into the gum of the implant area 90. The transmission member 83 is a steel wire, and the intermediate transmission mechanism further includes a sleeve 86, one end of the steel wire is connected to the pressing member 81, and the opposite end penetrates through the sleeve 86 and abuts against the marking member 82 along a direction perpendicular to the marking direction. The intermediate transmission mechanism further includes a limiting member 87 fixed to the end of the third positioning member 30 for positioning, and the limiting member 87 has a cavity for the marking member 82 to penetrate through, and the limiting step 85 is arranged on the inner wall of the cavity. The limiting member 87 can be clamped in the positioning ring 32 of the third positioning member 30. A communication hole is arranged on the side wall of the limiting member 87 and communicates with the cavity, and the steel wire penetrates into the cavity from the communication hole and abuts against the marking member 82 in the cavity. The end of the movable member 43 away from the first positioning member 10 is provided with a button hole 433, the pressing member 81 is arranged at the position of the button hole 433, and one end of the pressing member 81 is exposed outside the button hole 433. The sleeve 86 penetrates into the hollow cavity of the fixed member 50 from the button hole 433 and extends to the position communicating with the communication hole. When the third positioning member 30 is located at the middle position of the implant area, if the pressing member 81 is not pressed, the marking member 82 is abutted against the limiting step 85 by the second elastic member 84, and at this time, the pressing member 81 is located above the position of the alveolar bone to be marked. At this time, the medical staff can press the pressing member 81 to drive the steel wire to move forward, and the end of the steel wire abutting against the marking member 82 pushes the marking member 82 away from the limiting step 85. When the marking member 82 moves away from the limiting step 85, the second elastic member 84 drives the marking member 82 to move towards the alveolar bone, so that the marking member 82 penetrates into the gum to complete the marking.

[0088] As shown, Figures 15 to 17 In addition, the embodiment can further be provided with a reset spring 88 on the side of the marking member 82 opposite to the steel wire, and when the pressing member 81 is not pressed, the reset spring 88 can keep the marking member 82 at the position limited by the limiting step 85.

[0089] In the embodiment, the end of the third positioning member 30 for positioning is further provided with a second measuring member 31 for measuring the position of the marking member 82 along the third direction, and the third direction is perpendicular to both the marking direction and the moving direction of the third positioning member 30.

[0090] As Figure 15 and Figure 21 shown, the second measuring member 31 can be designed as a strip-shaped scale extending along the third direction, and a scale and scale values for measuring distance can be provided on the second measuring member 31 along the third direction, so that the distance of the marking member 82 moving along the third direction can be conveniently obtained through the scale and scale values.

[0091] In order to facilitate positioning and marking operations, the length direction of the fixing member 50 and the length direction of the third positioning member 30 are perpendicular in the embodiment based on the foregoing embodiment. Thus, the pulley transmission oral implant positioning device of the embodiment is overall in an "L" shape. The first positioning member 10, the second positioning member 20 and the third positioning member 30 are arranged at 90 degrees with the fixing member 50. And since the pulley transmission mechanism is adopted, the operation end composed of the adjusting member 60 and the pressing member 81 and the working end composed of the first positioning member 10, the second positioning member 20 and the third positioning member 30 are respectively located at two ends of the fixing member 50, so that when the working end is inserted into the patient's oral cavity, the operation end can be located at a position far away from the patient's oral cavity and face, and is not easily blocked, and medical staff can easily observe and measure the measuring condition and positioning position in the oral cavity, and the operation is also convenient. Thus, the pulley transmission oral implant positioning device of the embodiment is convenient for medical staff to insert the working end into the patient's oral cavity and is also convenient for medical staff to perform positioning and marking operations.

[0092] In the embodiment, the components of the pulley transmission oral implant positioning device are assembled in a detachable manner, so as to maintain and replace the components. The assembly process is shown in Figure 18 and Figure 19 .
