FIG. 1
[0001] The present disclosure relates to the technical field of medical apparatus and instruments, in particular to an improved dental curet for department of stomatology.
[0002] Dental curettes are commonly used dental instruments for removing tooth fragments, residues, or scraping granulomas, cysts, diseased tissues in the alveolar cavity, and decaying bone during oral surgery. The dental curette is composed of a curette handle and spoon-shaped scraping blades at both ends of the handle. Dental curettes are dental instruments used for exploring the alveolar cavity after tooth extraction, and removing foreign bodies (calculus, dental fragments, bone fragments and the like), inflammatory tissues, granulomas, dental sacs and the like in the alveolar cavity. Therefore, the purposes of thoroughly cleaning the extraction cavity and reducing complications such as infection and bleeding after extraction are achieved.
[0003] Dental curettes are divided into two types of straight type and angled type according to whether the scraping blades are angled or not. The purpose of the scraping blades designed to be angled is to facilitate the cleaning of foreign bodies in various parts of the tooth extraction socket; according to the shape of the curette handle, the dental curette is divided into two types of round handle and flat handle; according to the number of the scraping blades, the dental curette is divided into two types of double-headed type and single-headed type; and in addition, the difference between different types of curettes mainly lies in the sizes of the scraping blades.
[0004] As mentioned above, the current curette in the prior art has the following technical problems: firstly, the spoon-shaped scraping blade structures of the dental curette are generally spoon-shaped, and the dental curette is in point contact during cleaning, which is low in efficiency and ease of operation during operation; and secondly, generally, the length of the curette handle is fixed regardless of a single-headed or double-headed curette, which is not easy to operate. Therefore, an improved dental curette is designed by the applicant based on this.
[0005] Aiming at the above-mentioned problems existing in the prior art, the present disclosure provides an improved dental curette. By designing scraping blades consistent with the anatomic structure of a tooth outline and a telescopic scraping handle, the dental curette for department of stomatology is more convenient in the using process.

[0033] In the present disclosure, different scraping blades are designed according to the types of the connecting part and the scraping blade heads for selection and application; and each spoon shaped scraping blade head is an inwardly concave arc surface as a whole, so that the whole is a spoon-shaped structure.
[0034] Embodiment II
[0035] The technical scheme of the present disclosure is as follows:
[0036] The working sections of each arc-shaped notch sequentially comprise a first working section, a second working section and a third working section, radian included angles corresponding to the first working section, the second working section and the third working section are alpha, beta and gamma, and radian radii corresponding to the first working section, the second working section and the third working section are a, b and c.
[0037] The radian included angle beta corresponding to the second working section is larger than the radian included angles alpha and gamma corresponding to the first working section and the third working section; and the radian radius b corresponding to the second working section is larger than the radian radii a and c corresponding to the first working section and the third working section.
[0038] The radian included angles alpha, beta and gamma corresponding to the first working section, the second working section and the third working section are 5-15 degrees, 15-25 degrees and 5-15 degrees respectively.
[0039] The first working section, the second working section and the third working section of each arc-shaped notch are designed into different types according to the anatomic structures of teeth.
[0040] Based on the above-mentioned embodiment, combined with FIG. 5 in the specification, for the first working section, the second working section and the third working section of each arc-shaped notch in the present disclosure, different types of the working sections are designed according to corresponding arc length angles and radii, that is, according to patients and different teeth, corresponding content of the corresponding peripheral anatomic structure of the tooth to perform related operation, and at the same time, in the technical scheme of the present disclosure, different types are designed according to the specifications of the first working section, the second working section and the third working section.
