Description

Technical Field

[0001] The utility model relates to the technical field of oral medical instruments, in particular to a screwdriver for an internal corner hole of a dental implant. Background Art

[0002] During the dental implant process, the implant is first screwed into the alveolar bone through a thread; then the denture is installed on the implant. Since the implant needs to be installed in the mouth where the space is small, the implant generally uses an internal angle hole screw structure for easy installation.

[0003] After searching, the Chinese patent with publication number "CN220632254U discloses a dental implant internal angle hole screwdriver, which relates to the technical field of oral medical devices. The utility model includes an operating handle and a screwdriver head, the hinged end of the operating handle is fixedly installed with a shell, the inner top of the shell is fixedly installed with a rotating shaft, and the bottom end of the rotating shaft passes through the inner bottom of the shell and extends to the outside of the shell. The utility model fixes the hinged end of the operating handle with the shell so that the operating handle and the shell can be hinged, which is convenient for adjusting the angle between the screwdriver head and the operating handle, and controls the direction of the unidirectional rotation of the rotating shaft through a one-way rotating component, so that it is convenient to reverse the hand when tightening the implant, and supports the lens and LED lamp beads through a bracket. Under the effect of mirror reflection, the lens makes it convenient for dentists to observe the patient's oral cavity, and the LED lamp beads make it convenient to illuminate the patient's oral cavity, so as to facilitate the dentist's observation. However, the prior art has the following shortcomings when used:

[0004] The hinged end of the operating handle and the shell are fixedly installed, which is convenient for adjusting the angle between the screwdriver head and the operating handle. However, when the shell is rotated by the operating handle, the operating handle may rotate and touch the patient's lips or teeth. After the angle of the operating handle is adjusted, it needs to be fixed to ensure safety during use.

[0005] Therefore, a dental implant internal angle hole screwdriver is urgently needed to solve the above problems. Summary of the invention

[0006] The purpose of the utility model is to facilitate the adjustment of the angle between the screwdriver head and the operating handle in view of the existing fixed installation of the hinged end of the operating handle and the shell. However, when the shell is rotated by the operating handle, the operating handle may rotate and touch the patient's lips or teeth. After the angle of the operating handle is adjusted, it is necessary to fix it to ensure safety during use.

[0007] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0011] As a preferred technical solution of the present application, a magnet is embedded in the top of the fixing groove, and the magnet is used to fix the screwdriver head.

[0012] As a preferred technical solution of the present application, a rubber sheath is provided on the operating handle.

[0013] As a preferred technical solution of the present application, the front and back sides of the circular connecting block are both in contact with the U-shaped mounting block.

[0014] As a preferred technical solution of the present application, the positioning block fits with the U-shaped mounting block.

[0015] As a preferred technical solution of the present application, the mounting hole and the plug hole are both compatible with the fixed plug rod.

[0016] As a preferred technical solution of the present application, the through hole is adapted to the positioning rod.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the scheme of this application:

[0019] By means of the provided connecting shaft, circular connecting block, mounting hole, fixing block, tension spring, positioning block, plug hole, fixing plug rod, through hole and positioning rod, the positioning block is pulled to the side away from the U-shaped mounting block, the tension spring is deformed by the tensile force, so that the positioning rod is disengaged from the through hole, and the fixing plug rod is disengaged from the mounting hole. Then the staff rotates the circular connecting block by the operating handle, adjusts the angle of the operating handle to a suitable position, releases the positioning block, and drives the positioning block to move in the direction close to the U-shaped mounting block by the tension of the tension spring, so that the positioning block fits with the U-shaped mounting block, and the fixing plug rod is inserted into the corresponding mounting hole. The two positioning rods are respectively inserted into the two through holes to fix the circular connecting block, so that when the staff rotates the screwdriver head through the operating handle to tighten the implant, the operating handle itself will not rotate, ensuring safety during use. This solves the problem that the hinged end of the operating handle and the shell are fixedly installed in the prior art, and it is convenient to adjust the angle between the screwdriver head and the operating handle. However, when the shell is rotated by the operating handle, the operating handle may rotate, thereby touching the patient's lips or teeth. After the angle of the operating handle is adjusted, it needs to be fixed to ensure safety during use. BRIEF DESCRIPTION OF THE DRAWINGS
