Description

Technical Field

[0001] The utility model relates to the technical field of dental implant hole enlargement, in particular to a high-stability dental implant hole enlargement drill. Background Art

[0002] Dental implants, also known as artificial dental implants, are not natural teeth. Instead, pure titanium, highly compatible with human bone, is precisely engineered and processed into a cylindrical or other shape resembling a tooth root. These are surgically implanted into the alveolar bone of an edentulous area. A reamer is a tool used to enlarge a hole. It typically consists of a rotatable cutting head and a clamping mechanism. While its external shape is similar to a regular drill bit, its internal structure differs.

[0003] When a dentist performs dental implants on a patient, the patient's gums need to be enlarged. The dentist achieves this by using a reamer. During long-term reaming operations, the connection between the reamer and the mounting instrument is prone to loosening, thereby affecting the overall stability of the reamer during operation. Utility Model Content

[0007] By setting up the installation mechanism, after the staff installs the installation rod and the installation location, they can increase the overall stability of the connecting rod and the installation location by rotating the rotating component set in the rotating groove.

[0008] In a preferred solution, the material guiding mechanism includes a material guiding groove provided on the outer surface of the drill bit, and the material guiding groove is spirally opened on the outer surface of the drill bit.

[0009] By setting up a material guide mechanism, when the drill bit rotates to expand the hole, the powder generated by the expansion can be accumulated and collected inside the material guide groove, preventing the powder from falling into the denture.

[0010] In a preferred embodiment, the rotating assembly includes a bolt arranged inside the rotating groove, a rotating knob is installed at one end of the bolt, the bolt and the rotating groove are threadedly connected, the rotating knob is arranged on the outer surface of the connecting rod, the bolt is arranged at the center of the movable groove, and one end of the bolt is arc-shaped.

[0011] By setting up a rotating assembly, the bolt is driven to rotate by turning the knob, so that the bolt and the rotating groove are threadedly connected, and at the same time the bolt extends through the rotating groove to the inside of the movable groove. When the rotating knob loses force, the bolt and the rotating groove can be self-locked.

[0012] In a preferred solution, the sliding assembly includes a spring block arranged inside the movable groove, one end of the spring block is arc-shaped, the number of the spring blocks is two groups, and one end of the two groups of spring blocks with an arc shape is arranged at the front end of the bolt.

[0013] By arranging the sliding assembly, the two groups of spring blocks can be squeezed by rotating the bolts, so that the spring blocks slide outward through the extension opening.

[0014] In a preferred solution, the size of the spring block is adapted to the size of the extension opening, and the spring block and the extension opening are arranged on the same horizontal plane.

[0015] First, by setting up the installation mechanism, the staff can increase the overall stability of the connecting rod and the installation location by installing the installation rod and the installation location and then rotating the rotating component set in the rotating groove;

[0016] Secondly, by setting up a material guide mechanism, when the drill bit rotates to expand the hole, the powder generated by the expansion can be accumulated and collected inside the material guide groove, preventing the powder from falling into the denture. BRIEF DESCRIPTION OF THE DRAWINGS
