Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an oral curette. Background Art

[0002] An oral curette is a dental instrument used to remove tooth fragments, residues, or scrape granulomas, inflammatory tissues and granulomas, dental follicles, etc. during oral surgery, so as to achieve the purpose of cleaning foreign objects in the dental socket, removing diseased tissue, and reducing the occurrence of complications such as infection and bleeding after tooth extraction.

[0003] At present, the most common oral curette working end in clinical practice is a simple spoon-shaped structure with a single structure. This shape of curette has three major defects:

[0004] First, when cleaning the tooth socket, the traditional spoon-shaped working end has two working ends, and the spoon parts are in opposite directions. Each working end can only clean foreign matter on one surface, and the effect is poor when used on other surfaces. Cleaning different surfaces requires switching working ends, which is complicated and easy to cause contamination of instruments, increasing the possibility of nosocomial infection during and after surgery;

[0005] Secondly, the tooth sockets are generally deep pit-shaped and of different sizes. When traditional oral curettes are used to treat different tooth sockets, it is necessary to switch to a curette that is suitable for the size of the tooth socket, which makes the workflow messy and cumbersome, and the work efficiency is low.

[0006] Third, when working on the patient's oral cavity, the light in the oral cavity is often blocked due to force majeure, making the work more difficult;

[0007] In short, the traditional oral curette has low scraping efficiency, poor cleaning effect, is complicated to use, takes a long time to operate, and increases the workload of medical staff. These defects are not conducive to clinical use and have an adverse effect on the surgical effect. Summary of the invention

[0008] The utility model aims to overcome the deficiencies of the prior art and provide an oral curette to solve the problems of complicated use and low working efficiency of the existing traditional oral curette.

When the spiral tube is rotated outward, the spiral column drives the connecting wire rope to rotate, and the connecting wire rope pulls the umbrella-shaped spoon portion to close to the connecting rod. When the spiral tube is rotated inward, the umbrella-shaped spoon portion expands outward around the connecting rod. By controlling the size of the expansion of the umbrella-shaped spoon portion, scraping operations can be performed on tooth sockets of different sizes.

[0014] Preferably, one end of the focusing tube is connected to the connecting rod, and the other end is connected to the handle. A reflective film is attached to the inner wall of the focusing tube, and the reflective film is a thin film that can fully reflect light.

[0015] Preferably, the lighting lamp is placed in a focusing tube, a battery assembly is installed in the handle to provide power for the lighting lamp, one end of the lighting lamp is connected to the battery assembly, a detachable battery assembly cover is provided on the surface of the handle, and a lighting lamp switch is provided on one side of the cover.

[0016] Preferably, the reflected light channel is placed inside the connecting rod, the reflected light channel is connected to the focusing tube, and a reflective film is provided on the surface of the reflected light channel.

[0017] Preferably, a light outlet is provided on the surface of the connecting rod near the upper position of the umbrella-shaped spoon portion, and the light outlet is placed in four different directions on the surface of the connecting rod. The light outlet is connected to the reflected light channel, and the light of the lighting lamp can be emitted from the light outlet through the focusing tube and the reflected light channel to irradiate the surrounding area of ​​the oral disease.

[0018] Beneficial effects: The oral scraper of the utility model has a spoon folding device that can adjust the size of the umbrella-shaped spoon part, and can complete the cleaning of tooth sockets of various sizes. The end of the umbrella-shaped spoon extension piece of the umbrella-shaped spoon part is serrated, which can effectively scrape away foreign matter in the oral cavity. The scraping components are distributed in three different directions, and can complete the cleaning of the oral cavity in different directions, avoiding the disadvantage of the traditional oral scraper that the working end must be constantly switched. Through the lighting device, light can be directly transmitted to the patient's part in the oral cavity, solving the problem of dim light in the oral cavity. In short, the oral scraper involved in the utility model has high scraping efficiency, good cleaning effect, simple operation, reduces the workload of medical staff, and enhances the effect and efficiency of oral scraping.
