Description

Technical Field

[0001] This utility model relates to the field of dental implant technology, specifically to an anti-slip transfer rod for dental implants. Background Technology

[0002] An implant anti-slip transfer bar is an accessory used during oral implant surgery to precisely transfer the shape and position of the implant tip from inside the mouth onto a working model.

[0003] Existing dental implant transfer rods are generally single rods. When taking impressions for patients with multiple consecutive missing teeth, multiple transfer rods are required. Due to the large overall span, multiple transfer rods may wobble in the silicone rubber used for taking impressions, resulting in inaccurate impression results.

[0004] Therefore, a non-slip transfer rod for dental implants is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a non-slip transfer rod for dental implants in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A dental implant anti-slip transfer rod includes a rod body, a screw connector for connecting to an implant fixedly connected to the bottom of the rod body, a sleeve rod slidably sleeved on the surface of the rod body, a locking component for limiting the sleeve rod on the surface of the rod body, a round shaft fixedly connected to the top of the sleeve rod, a connecting rod assembly movably engaged on the surface of the round shaft, and a clamping component for limiting the connecting rod assembly on the surface of the round shaft.

[0008] Furthermore, the locking assembly includes a mounting groove, which is formed inside the rod body. A spring is fixedly connected to the inner wall of the mounting groove, and a slider is fixedly connected to the free end of the spring. The surface of the slider is slidably connected to the inner wall of the mounting groove. A pin is fixedly connected to the side of the slider. A pin hole is formed through the surface of the sleeve rod, and the end of the pin is movably engaged with the inner wall of the pin hole.

[0009] Furthermore, the number of pin holes is two.

[0010] Furthermore, the linkage assembly includes a crossbar, and both ends of the crossbar are fixedly connected with semi-circular arc strips, which are adapted to the circular shaft.

[0011] Furthermore, the clamping assembly includes an internal threaded ring, and the inner wall of the internal threaded ring is threadedly connected to the surface of the round shaft. A pressure ring is fixedly connected to the bottom of the internal threaded ring, and the bottom surface of the pressure ring is in contact with the top surface of the semi-circular arc strip.

[0012] Furthermore, the top surface of the circular shaft is provided with anti-slip protrusions.

[0013] The beneficial effects of this utility model are as follows:

[0014] By taking the round shaft, aligning the screw connector with the implant, and connecting the screw connector to the implant, after connection, use the locking component to release the restriction on the sleeve, pull down the sleeve so that the sleeve slides down along the surface of the rod, shortening the total length of the rod and sleeve, so that the patient's mouth does not need to open too wide an angle. After connecting the adjacent screw connectors to the implant, use the connecting rod assembly to connect the adjacent round shafts, and then use the clamping component to fix the connecting rod assembly, thus achieving a rigid connection between the adjacent round shafts. Then the impression taking process can be carried out. In the process of taking impressions for patients with multiple consecutive missing teeth, this utility model can effectively fix multiple transfer rods and prevent the transfer rods from shaking during the impression taking process, thereby ensuring the stability of the impression taking process.

Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0023] In the description of the embodiments of this utility model, it should be noted that the terms "inner", "outer", "upper", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] like Figures 1 to 4 As shown, a dental implant anti-slip transfer rod includes a rod body 1, a screw connector 2 for connecting to the implant is fixedly connected to the bottom of the rod body 1, a sleeve rod 3 is slidably sleeved on the surface of the rod body 1, a locking component 4 for limiting the sleeve rod 3 is provided on the surface of the rod body 1, a round shaft 6 is fixedly connected to the top of the sleeve rod 3, a connecting rod assembly 5 is movably snapped onto the surface of the round shaft 6, and a clamping component for limiting the connecting rod assembly 5 is provided on the surface of the round shaft 6. More specifically, by taking the round shaft 6, aligning the screw connector 2 with the implant, and connecting the screw connector 2 to the implant, after the connection is completed, the locking component 4 is used to release the restriction on the sleeve 3, and the sleeve 3 is pulled down so that the sleeve 3 slides down along the surface of the rod 1. The total length of the rod 1 and the sleeve 3 will be shortened, so the patient's mouth does not need to be opened at an excessive angle. After connecting the adjacent screw connector 2 to the implant, the connecting rod component 5 is used to connect the adjacent round shaft 6, and then the clamping component is used to fix the connecting rod component 5, so that the rigid connection of the adjacent round shaft 6 can be achieved. Then the impression taking process can be carried out.

[0025] The locking assembly 4 includes a mounting groove 401, which is located inside the rod body 1. A spring 402 is fixedly connected to the inner wall of the mounting groove 401, and a slider 403 is fixedly connected to the free end of the spring 402. The surface of the slider 403 is slidably connected to the inner wall of the mounting groove 401. A pin 404 is fixedly connected to the side of the slider 403. A pin hole 405 is formed through the surface of the sleeve rod 3, and the end of the pin 404 is movably engaged with the inner wall of the pin hole 405. It should be noted that by pressing the pin 404, the slider 403 is moved, thereby compressing the spring 402. The end of the pin 404 will disengage from the inner wall of the pin hole 405, thereby releasing the restriction on the sleeve rod 3. Pulling the sleeve rod 3 up and down can cause it to slide on the surface of the rod body 1, thereby adjusting the overall length of the rod body 1 and the sleeve rod 3.

[0026] There are two pin holes 405. More specifically, when the end of the pin 404 is inserted into the inner wall of the lower pin hole 405, the total length of the rod 1 and the sleeve 3 is at its longest, which makes it convenient for medical staff to pick up. When the transfer rod is placed inside the oral cavity, the upper pin hole 405 can be engaged with the pin 404, which shortens the total length of the rod 1 and the sleeve 3, so that the user's oral cavity does not need to be opened too wide.

[0027] The linkage assembly 5 includes a crossbar 501, with semi-circular arc strips 502 fixedly connected to both ends of the crossbar 501. The semi-circular arc strips 502 are adapted to the circular shafts 6. It should be noted that by connecting the two semi-circular arc strips 502 to two adjacent circular shafts 6, and using the crossbar 501 to support the two semi-circular arc strips 502, a rigid connection is maintained between adjacent transfer rods, thereby reducing the swaying of the transfer rods.

[0028] The clamping assembly includes an internally threaded ring 8, the inner wall of which is threadedly connected to the surface of the round shaft 6. A pressure ring 9 is fixedly connected to the bottom of the internally threaded ring 8, and the bottom surface of the pressure ring 9 is in contact with the top surface of the semi-circular arc strip 502. More specifically, by rotating the internally threaded ring 8, the internally threaded ring 8 will move downward under the action of the thread, thereby pushing the pressure ring 9 down. The pressure ring 9 then presses against the top surface of the semi-circular arc strip 502, thereby fixing the semi-circular arc strip 502.

[0029] The top surface of the round shaft 6 is provided with anti-slip protrusions 7. It should be noted that by providing anti-slip protrusions 7, the friction when picking up the round shaft 6 is increased, thus achieving an anti-slip effect.

[0030] In summary: By taking the round shaft 6, aligning the screw connector 2 with the implant, and connecting the screw connector 2 to the implant, after the connection is completed, the locking component 4 is used to release the restriction on the sleeve 3, and the sleeve 3 is pulled down, causing the sleeve 3 to slide down along the surface of the rod 1. The total length of the rod 1 and the sleeve 3 will be shortened, and the patient's mouth does not need to be opened at an excessive angle. After connecting the adjacent screw connector 2 to the implant, the connecting rod component 5 is used to connect the adjacent round shaft 6, and then the clamping component is used to fix the connecting rod component 5, thereby achieving a rigid connection between the adjacent round shafts 6. Then the impression taking process can be carried out. In the process of taking impressions for patients with multiple consecutive missing teeth, this utility model can effectively fix multiple transfer rods and avoid the transfer rods from shaking during the impression taking process, thereby ensuring the stability of the impression taking process.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
