Abstract
The utility model discloses a cavity preparation working tip with a planar end part, which comprises a working tip connecting part, a working tip neck handle part and a working tip head part, wherein the working tip connecting part is provided with a cavity; one end of the working tip connecting part is connected with the ultrasonic handle, and the other end is connected with one end of the working tip handle part; the other end of the working tip handle part is connected with one end of the working tip head part, wherein one end of the working tip head part far away from the working tip handle part is a plane, the surface of the plane is plated with silicon carbide, and the joint of the working tip handle part and the working tip head part forms an arc. The end face of the working tip part is a plane coated with silicon carbide, so that excessive normal tooth tissues are cut when the cavity is trimmed, and meanwhile, the hidden danger of broken needle caused by sand plating is avoided.
Description
Technical Field
The utility model relates to the field of dental medical appliances, in particular to a cavity preparation working tip with a plane end part.
Background
The cavity refers to a cavity which is prepared by removing caries tissues by adopting a dental surgical operation method and according to requirements. The cavity has a certain shape and can contain and support filling materials, thereby achieving the purpose of restoring the shape and function of teeth. In oral surgery, an ultrasonic tip is typically used to prepare the cavity in order to preserve as much healthy dental tissue as possible. The existing ultrasonic working tip for preparing the cavity is mainly spherical and hemispherical in tip, and when the bottom surface and corners of the cavity are trimmed, more tooth tissues are needed to be cut, so that caries or protrusion can be removed.
Disclosure of utility model
The invention aims to solve the problems that the adjacent tooth surface cavities are difficult to prepare and more healthy tooth tissues are reserved, and provides a cavity preparation working tip with a plane end part.
The technical scheme for realizing the aim of the utility model is as follows:
A cavity preparation working tip with a planar end part comprises a working tip connecting part, a working tip neck handle part and a working tip head part; one end of the working tip connecting part is connected with the ultrasonic handle, and the other end is connected with one end of the working tip handle part; the other end of the working tip handle part is connected with one end of the working tip head part, wherein one end of the working tip head part far away from the working tip handle part is a plane, and the surface of the plane is sprayed with silicon carbide, and the joint of the working tip handle part and the working tip head part forms an arc.
The plane is a circular plane, and the diameter of the circle is 0.6mm-4.0mm.
The plane is parallel to the cross section of the tip portion.
The tip portion and the tip neck portion are not in the same plane.
According to the preparation working tip for the hole with the planar end part, the end face of the working tip part is the plane coated with silicon carbide, so that excessive normal tooth tissues are cut when the hole is trimmed, and meanwhile, the hidden danger of broken needle caused by plating is avoided, so that in the process of preparing the hole, the local position of the flat hole is decorated by the working tip with the planar end part, and only the tip is plated with sand, so that the working tip cannot cut peripheral healthy tissues.
Drawings
FIG. 1 is an elevation view of a flat-ended cavity preparation tip of example 1;
FIG. 2 is a top view of an end planar cavity preparation tip of example 1;
FIG. 3 is a left side view of FIG. 1;
In the figure: 1. the hydraulic wrench comprises a working tip connecting part 2, a working tip handle part 3, a working tip part 4, a working tip part end plane 5, a wrench position 6, a water outlet tank 7 and a water outlet.
Description of the embodiments
The present utility model will now be further described with reference to the accompanying drawings and examples, which are not intended to limit the scope of the utility model.
Examples
As shown in fig. 1, 2 and 3:
The cavity preparation working tip with the planar end part comprises a working tip connecting part 1, a working tip neck handle part 2 and a working tip head part 3; one end of the working tip connecting part 1 is connected with the ultrasonic handle, and the other end of the working tip connecting part 1 is connected with one end of the working tip handle 2; the other end of the tip handle 2 is connected with one end of the tip head 3, wherein one end of the tip head 3 far away from the tip handle 2 is a plane 4, the surface of the plane 4 is sprayed with silicon carbide, and the joint of the tip handle 2 and the tip head 3 forms an arc; the connecting part 1 of the working tip is connected with an ultrasonic handle, and ultrasonic equipment provides power for the working tip to vibrate, so that the head part 3 of the working tip cuts caries parts in teeth.
The plane 4 is a round plane, and the diameter of the round plane is 0.6mm-4.0mm.
The plane 4 is parallel to the cross section of the tip portion 3.
In the embodiment, the working tip connecting part is connected with one end of the ultrasonic handle, the bottom surface of the working tip connecting part is internally and coaxially provided with internal threads, the internal threads are in threaded connection with external threads outside the ultrasonic handle, the outer circumference of a section of the working tip connecting part, which is close to the working tip handle, is provided with inwards concave wrench positions, and the number of wrench positions in the embodiment is 2; the spanner positions can be set to be 4 or 6, and are evenly distributed at intervals and are opposite to each other.
As shown in fig. 3, the tip handle 2 is further provided with a water outlet tank 6, and a water outlet 7 is arranged on the water outlet tank 6 and is positioned in the middle of the tip handle 2.
As shown in fig. 1, 2 and 3, the tip portion of the present embodiment has a cylindrical shape with a constant diameter from the tip shank portion toward the grinding head end of the tip portion.
In addition to the fact that the tip portion 3 and the tip handle portion 2 of the present embodiment are in the same plane, the tip portion 3 and the tip handle portion 2 may be disposed out of the same plane, which is advantageous for a doctor to choose a proper direction of entry into the teeth during use.
