Description

Consumption type tooth perforator

Technical Field

The utility model belongs to the technical field of tooth planting technique and specifically relates to a consumption type tooth perforator

Background

When the tooth is implanted, a plurality of steps are required, each of which is spaced apart for a long time, and since the bone is drilled to grow cartilage in the gap, the surrounding cartilage needs to be cleaned each time the next step is performed.

When cleaned with existing instruments, it can damage the tissue surrounding the cartilage, thereby causing damage to the surrounding bone.

SUMMERY OF THE UTILITY MODEL

The utility model provides a consumption type tooth perforator, which can effectively remove the newly expanded cartilage and does not damage the bone around well.

A consumable tooth perforator comprises a handle, wherein the handle is provided with a rotating part, the rotating part is connected with a drill bit, the hardness of the drill bit is 500-.

Further, the drill includes a connection portion and a consumption portion, and the rotation portion has a hardness greater than that of the consumption portion.

Further, the rotating part is provided with symmetrically arranged convex parts, and the drill bit is provided with a groove corresponding to the convex parts.

Further, the bit profile is cylindrical.

Further, the handle is provided with a switch, and the switch controls the motor to rotate.

Adopt the technical scheme of the utility model, following technological effect has:

since the drill has a hardness of 500-. Thus effectively preventing damage to surrounding bone during removal of cartilage.

Through the connection structure of connecting portion and drill bit, after the drill bit wearing and tearing, can conveniently take off the drill bit and change the drill bit of new.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

The first embodiment is as follows:

it is to be noted that, in the description of the present invention, "a plurality" means two or more unless otherwise specified; the terms "upper", "lower", "left", "right", "inner", "outer", "front", "rear", "head", "tail", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are merely for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention.

Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

Meanwhile, in the description of the present invention, unless otherwise explicitly specified or limited, the terms "connected" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; the connection can be mechanical connection or electrical connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A consumable tooth perforator comprises a handle 1, wherein the handle 1 is provided with a rotating part 2, the rotating part 2 is connected with a drill bit 3, the drill bit 3 comprises a connecting part 34 and a rod part 33, the hardness of the rod part 33 is 500-.

Further, the rotating part 2 is provided with symmetrically arranged protrusions 21, and the drill 3 is provided with grooves 31 corresponding to the protrusions 21. The rotating portion 2 is provided with a through hole, the protruding portion 21 is provided with a rod portion 22, the protruding portion 21 is arranged on the inner side wall of the rotating portion 2, the rod portion 22 penetrates through the through hole and extends to the periphery of the rotating portion 2, the end portion of the rod portion 22 is provided with a pressing portion 23, the periphery of the rotating portion 2 is provided with a semicircular bulge 25, and the pressing portion 23 and the semicircular bulge 25 are connected through a spring 24. When pressure is applied to the pressing portion 23, the entraining spring 24 is deformed to entrain the protruding portion 21 along the outer circumference of the rotating portion 2 via the rod portion 22, thereby allowing the drill bit 3 to be taken out. When the drill 3 is inserted into the rotary part 2, the outer periphery of the drill 3 abuts against the projection 21 so that it moves to the outer periphery, and when the recess 31 of the drill 3 is rotated to the projection 21, the projection 21 is inserted into the recess 31, thereby fixing the drill 3. The motor can drive the drill bit to rotate through the east of Guandong.

Further, the drill bit 3 is cylindrical in profile.

Further, the handle 1 is provided with a switch 11, and the switch 11 controls the motor 4 to rotate.

It is to be understood that the number of the projections 21 is not limited to two, and may be 4 or more.

Since the drill has a hardness of 500-. Thus effectively preventing damage to surrounding bone during removal of cartilage.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
