Detailed Implementation
[0023] The present invention will be further described below with reference to the accompanying drawings.
[0024] like Figures 1 to 3 As shown, a preferred embodiment of the dental implant locator of this utility model includes a base 1, a positioning base 2, a drill positioning ring 3, and an adjustment mechanism 4. The positioning base 2 is mounted on the base 1. There are two positioning bases 2, located at opposite ends of the base 1. The positioning bases support the base 1 and position it on the teeth, indirectly securing the base 1 to the teeth. Both the drill positioning ring 3 and the base 1 have holes for defining the drill bit. The drill positioning ring 3 is rotatably mounted on the base 1. The adjustment mechanism 4 is connected to both the drill positioning ring 3 and the base 1, allowing adjustment of the rotation angle of the positioning ring.
[0025] The adjusting mechanism 4 includes an adjusting screw 41, an adjusting nut 42, a movable sleeve 43, and a telescopic rod 44. The upper end of the adjusting screw 41 passes through the movable sleeve 43, and the lower end of the adjusting screw 41 is screwed onto the base 1. Two adjusting nuts 42 are provided on the adjusting screw 41, located on the upper and lower sides of the movable sleeve 43, respectively. Both adjusting nuts 42 abut against the movable sleeve 43, fixing the movable sleeve 43 to the adjusting screw 41 so that it cannot move. The movable sleeve 43 is rotatably mounted on the telescopic rod 44, which consists of two telescopic rods located at opposite ends of the movable sleeve 43. Both telescopic rods 44 are mounted on the drill bit positioning ring 3. When angle adjustment is needed, the two adjusting nuts 42 are rotated, causing them to move on the screw. This, in turn, moves the movable sleeve 43 on the adjusting screw 41. As the movable sleeve 43 moves on the adjusting screw 41, the telescopic rod 44 extends or shortens adaptively under the influence of the movable sleeve 43. This causes the drill bit positioning ring 3 to rotate on the base 1, thus achieving angle adjustment of the drill bit positioning ring 3. The presence of two adjusting nuts 42 ensures that the adjusting screw 41 will not slide relative to the movable sleeve 43. The movable sleeve 43 and the adjusting screw 41 remain relatively fixed, thus preventing the movable sleeve 43 from moving. Without the movable sleeve 43 moving, the telescopic rod 44 will also remain stationary, and the drill bit positioning ring 3 will remain fixed.
[0026] The movable sleeve 43 has mounting rods 45 at both ends, which are screwed onto the movable sleeve 43 to facilitate the assembly of the movable sleeve 43 and the telescopic rod 44. The mounting rods 45 are inserted into the telescopic rod 44. The movable sleeve 43 has a through hole for the adjusting screw 41 to pass through, and the through hole is arranged along the thickness direction of the movable sleeve 43.
[0027] Each of the telescopic rods 44 includes an outer rod 441 and an inner rod 442. The outer rod 441 is disposed on the outer wall of the drill bit positioning ring 3. The outer rod 441 is provided with a sliding groove, which is arranged along the length direction of the outer rod 441. The sliding groove is recessed into the drill bit positioning ring 3 at the end of the outer rod 441 away from the drill bit positioning ring 3. The inner rod 442 is slidably disposed in the sliding groove of the outer rod 441. The mounting rod 45 passes through the corresponding inner rod 442.
[0028] The drill bit positioning ring 3 is provided with two symmetrical rotating shafts 46, which are rotatably mounted on the base 1. The axis of the rotating shaft 46 is perpendicular to the axis of the drill bit positioning ring 3, ensuring that the drill bit positioning ring 3 will not be eccentric when rotating around the axis. The drill bit positioning ring 3 has a certain height to ensure that it can contain the drill bit.
[0029] and combined Figure 4 For reference, the base 1 is provided with mounting plates 5, and there are two mounting plates 5, which are symmetrically arranged. The rotating shaft 46 of the drill bit positioning ring 3 is rotatably mounted on the mounting plates 5. The mounting plates 5 are provided with angle scales to facilitate quick determination of the deflection angle of the drill bit positioning ring 3. The rotating shaft 46 is provided with a pointer 6 on the rotating shaft 46 to indicate the deflection angle of the drill bit positioning ring 3; in other embodiments, it can also be a mark on the end face of the rotating shaft 46. The base 1 is provided with two locking parts 11, which are symmetrically arranged and are used to lock the positioning base 2. The locking base is provided with anti-slip teeth 12, which are used to cooperate with the positioning base 2 to prevent the positioning base 2 from sliding. The locking parts 11 are also provided with scales to indicate the straight-line distance between the positioning base 2 and the center of the drill bit positioning ring.
[0030] and combined Figure 5 For reference, each of the positioning bases 2 has a positioning groove 21 and a clamping piece 22. The positioning groove 21 is located at the bottom of the positioning base 2 and is arranged along the length direction of the positioning base 2. The end of the positioning groove 21 away from the drill bit positioning ring 3 is closed, and the end near the drill bit positioning ring 3 is set as an opening, which facilitates the adjustment of the position of the positioning base 2 along the length direction of the positioning base 2. At the same time, the lower side of the positioning groove 21 is also set as an opening, which facilitates the placement onto the tooth from the length down. There are two clamping pieces 22, which are arranged opposite each other. The clamping pieces 22 are clamped on the snap-fit part 11 on the base 1. The two clamping pieces 22 are clamped on the snap-fit part 11 by interference fit. Each clamping piece 22 is also provided with an anti-slip groove 23 adapted to the anti-slip tooth 12. This can ensure that the snap-fit part 11 will not slide in the length direction of the clamping piece 22, so that the position of the drill bit positioning ring 3 remains fixed and the drilling accuracy of the drill bit is improved.
[0031] In use, first adjust the adjusting nut 42 to ensure the drill bit positioning ring 3 has the required tilt angle, using the angle scale on the mounting plate 5. After this, attach the positioning base 2 to the locking part 11 from bottom to top. When locking, align the positioning base 2 with the corresponding length scale on the locking part 11 according to the width requirement of the implant. This ensures that the center of the drill bit positioning ring 3 is consistent with the required point. Then, attach the positioning base 2 to the tooth adjacent to the implant location, and then drilling can begin. The drill bit positioning ring 3 will not move when the adjusting nut 42 is stationary. Because the drill bit positioning ring 3 is fixed and guides the drill bit, it ensures that the drill bit maintains a consistent angle during drilling, resulting in a high-precision hole.
[0032] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structure made using the contents of this utility model specification and drawings, whether directly or indirectly applied to other related technical fields, shall also be within the patent protection scope of this utility model.
