Technical Field

The invention relates to the technical field of medical instruments, in particular to an improved dental curette for department of stomatology.

Background

The tooth curet is a medical instrument commonly used in dentistry for removing tooth fragments, residues or scraping granuloma, cyst, pathological tissues in tooth sockets and decayed bone during oral surgery. The tooth curet is composed of a curet handle and curet-shaped curet edges at two ends of the handle. The tooth curet is a dental instrument used for probing an alveolar socket after tooth extraction and removing foreign matters (tartar, dental debris, bone fragments and the like), inflammatory tissues, granuloma, tooth capsules and the like in the alveolar socket. So as to achieve the purposes of thoroughly cleaning the tooth extraction socket and reducing the occurrence of complications such as infection, bleeding and the like after tooth extraction.

The tooth curettage spoon is divided into a straight type and a bevel type according to whether the scraping edge is bevel or not. The scraping edge is designed into a bevel so as to be convenient for cleaning foreign matters at each part in the tooth pulling socket; according to the shape of the handle of the curette, the curette is divided into a round handle and a flat handle; according to the number of the scraping edges, the device is divided into a double-head type and a single-head type; in addition, the difference of different types of curettes is mainly reflected in the different sizes of the curettes.

As described above, the curette of the prior art has the following technical problems: 1) the spoon-shaped scraping edge structure of the tooth curette is generally spoon-shaped, and is point contact when cleaning, so that the efficiency and the operation convenience are poor in the operation process; 2) generally, the length of the curette handle is fixed and is inconvenient to operate no matter the curette is single-head or double-head. Accordingly, applicants have devised an improved dental curette based thereon.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides an improved dental curette which is more convenient to use by designing a scraping edge and a telescopic matched scraping handle according with the outline anatomical structure of teeth.

In order to achieve the technical purpose and achieve the technical effect, the invention is realized by the following technical scheme:

the improved dental curette comprises a curette blade and a curette handle, wherein the curette blade is fixedly arranged at two ends of the curette handle, the two ends of the curette handle are knurling rods, a telescopic part is arranged in the middle of the curette handle, the curette blade comprises a connecting part and a curette blade head, the straight head or the elbow of the connecting part is used as the curette blade head, an arc-shaped notch which is in accordance with the anatomical structure of the outline of teeth is formed in the side surface of the curette blade head, and the two ends of the arc-shaped notch are in smooth transition.

Furthermore, the outer edge of the spoon-shaped scraping edge head is a cutting edge, and the front side and the two sides of the spoon-shaped scraping edge head are in circular arc transition;

the working section of the arc-shaped notch is sequentially a first working section, a second working section and a third working section, the radian included angles corresponding to the first working section, the second working section and the third working section are alpha, beta and gamma, and the corresponding radian radiuses are a, b and c.

Further, 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; 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.

Furthermore, the radian included angles alpha, beta and gamma corresponding to the first working section, the second working section and the third working section are respectively 5-15 degrees, 15-25 degrees and 5-15 degrees.

Furthermore, the first working section, the second working section and the third working section of the arc-shaped notch are designed into different models according to the anatomical structure of the tooth.

Furthermore, the spoon-shaped scraping edge head is integrally an inwards concave cambered surface; the maximum length of the spoon-shaped scraping edge head is 0.5-1.5cm, and the maximum width is 0.3-0.5 cm.

Furthermore, the telescopic part is a telescopic rod.

The invention has the beneficial effects that:

the invention relates to an improved dental curette for department of stomatology, which comprises a curette blade and a curette handle, wherein the curette blade is fixedly arranged at two ends of the curette handle, knurling rods are arranged at two ends of the curette handle, a telescopic part is arranged in the middle of the curette handle, the curette blade comprises a connecting part and a curette blade head, the straight head or an elbow of the connecting part is provided with a curette blade head, an arc-shaped notch which is in accordance with the anatomical structure of the outline of teeth is arranged on the side surface of the curette blade head, and two ends of the arc-shaped notch are in a smooth transition shape;

compared with the prior art that the spoon is in a whole shape, the arc-shaped notch is formed in the side face of the spoon-shaped scraping blade head to be matched with the peripheral anatomical structure of teeth, so that only point contact can be performed on the teeth when the traditional curette scrapes tissues, and the spoon-shaped scraping blade head with the arc-shaped notch can change the contact area through matching of the arc-shaped notch end and the teeth, so that point contact is changed into surface contact, and efficient operation is performed;

the scraping handle comprises the knurled rods at two ends and the telescopic part in the middle, friction is increased due to the design of the knurled rods, and the length of the whole scraping handle can be changed due to the design of the telescopic part.

Of course, it is not necessary for any product in which the invention is practiced to achieve all of the above-described advantages at the same time.
