Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an auxiliary device for assembling a tooth implant guide plate. Background Art

[0002] An implant guide is a device that can help determine the direction and depth of implant placement during denture surgery. Figure 1 As shown, the implant guide includes a positioning plate 1 that matches the dental arch and a guide ring 2 set on the positioning plate. The positioning plate is made by 3D printing after digital design, and the positioning plate is generally made of resin material. The guide ring used to control the implant depth and direction is made of metal material through mechanical processing. The guide ring and the positioning plate need to be manually assembled after being made.

[0003] During the installation of the guide ring, since the clearance between the guide ring 2 and the guide ring mounting hole on the positioning plate is small, and the direction of installation can only be judged by the naked eye, and a slight deviation in the axial direction of the guide ring and the axial direction of the guide ring mounting hole may cause installation failure, the installation is often difficult to succeed in one go. Since the strength of the metal guide ring is much greater than that of the resin positioning plate, the deflection of the guide ring during installation will inevitably squeeze the positioning plate, which may cause problems such as deformation of the implant guide. After the secondary installation, the accuracy of the implant guide may be affected unpredictably, which runs counter to the original intention of precise implantation. In addition, the installation process is extremely time-consuming and requires a lot of manpower costs. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a planting guide assembly auxiliary device to solve the technical problems of improving the assembly efficiency of the guide ring and the positioning plate and avoiding the guide ring from deflecting and squeezing the positioning plate during the installation process to affect the accuracy of the planting guide.

[0005] The utility model planting guide plate assembly auxiliary device comprises a bracket, a support hook and a positioning push rod;

[0006] The bracket is composed of a horizontal arm and two vertical arms vertically connected to the horizontal arm, and a central positioning hole is provided in the middle of the horizontal arm;

[0007] The support hook is hinged on the lower end of the vertical arm;

[0008] The positioning push rod comprises a rod body and a retaining ring arranged in the middle of the rod body, wherein the retaining ring divides the rod body into an upper section and a lower section, the upper section slidingly cooperates with a central positioning hole on the cross arm, and the lower section slidingly cooperates with a guide ring.

[0009] Furthermore, the support hook is L-shaped.

[0010] Beneficial effects of the utility model:

[0011] The utility model relates to an auxiliary device for assembling a planting guide plate, which can ensure that the axis of the guide ring coincides with the axis of the guide ring mounting hole on the positioning plate during the installation process, thereby avoiding the problem of the guide ring eccentrically extruding the positioning plate and ensuring the accuracy of the assembled planting guide plate; and by using this device, the guide ring and the positioning plate can be assembled at one time, improving the assembly efficiency.

[0016] The following further describes the present utility model in conjunction with the drawings and embodiments.

[0017] As shown in the figure, the auxiliary device for assembling the planting guide plate in this embodiment includes a ╥ bracket 3, a hook 4, and a positioning push rod 5.

[0018] The ╥ bracket is composed of a cross arm 31 and two vertical arms 32 vertically connected to the cross arm, and a central positioning hole 33 is provided in the middle of the cross arm.

[0019] The hook 4 is hinged to the lower end of the vertical arm 32; the hook is L-shaped.

[0020] The positioning push rod 5 includes a rod body 51 and a retaining ring 52 provided in the middle of the rod body. The retaining ring divides the rod body into an upper section and a lower section. The upper section is slidably matched with the central positioning hole on the cross arm, and the lower section is slidably matched with the guide ring of the planting guide plate.

[0021] The method for assembling the positioning plate 1 and the guide ring 2 using this auxiliary device for assembling the planting guide plate is as follows:

[0022] The first step: Rotate the hook 4 to open it to both sides, and put the guide ring 2 on the lower section of the positioning push rod 5.

[0023] The second step: Insert the positioning push rod 5 into the positioning plate 1. As Figure 1 shown, the hole for installing the guide ring 2 on the positioning plate 1 is a stepped hole, and the positioning push rod 5 is inserted into the lower section hole of the stepped hole.

[0024] The third step: Rotate the hook 4 so that the hook 4 hooks the positioning plate 1.

[0025] Step 4: Fix the ╥ bracket 3 with a finger, and then push the positioning push rod 5 downward to press the guide ring 2 into the upper hole section of the stepped hole.

[0026] Step 5: Rotate the hook 4 to open it to both sides, and remove the planting guide plate assembly auxiliary device of the present invention.

[0027] By using the planting guide plate assembly auxiliary device in this embodiment, it can ensure that the axis of the guide ring coincides with the axis of the guide ring mounting hole on the positioning plate during the installation process, thus avoiding the problem that the guide ring eccentrically presses the positioning plate and ensuring the accuracy of the assembled planting guide plate; and by using this device, the guide ring and the positioning plate can be assembled at one time, improving the assembly efficiency.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them.
