Abstract

The utility model relates to a back-gingiva fistula scaling device, which comprises a handle (1), a working head (2), and a bend (4) that connects the handle (1) to the working head (2), wherein the working head (2) is positioned on the front end of the bend (4), the handle (1) forms a cylindrical shape, both ends of the handle (1) are provided with rough surfaces (3), the working head (2) is 10 mm to 20 mm long, the diameter of the cross section of the working head (2) is less than 3 mm and more than 0.3 mm, and the end surface of the front end of the working head (2) is provided with a drop pit (5). The utility model overcomes the defects of long time in treating a gingiva fistula and slow healing speed, which are caused by that the existing method of treatment can not treat chronically infected granulation tissues at the periphery of a root tip and in the fistula. The scaling device can be inserted into the fistula from an opening of the fistula and directly extended to a diseased region to thoroughly remove infected granulation tissues at the diseased region and in the fistula.

Description

Backteeth gingiva fistula curettage instrument

Technical field

This utility model relates to the medical apparatus and instruments that uses in a kind of medical treatment in the department of stomatology, and more particularly it is a kind of backteeth gingiva fistula curettage instrument.

Background technology

The gingiva fistula is one of disease very common in the oral cavity, and it can be caused that dental caries and periodontal disease the most common in the oral cavity all can cause the gingiva fistula by multiple oral disease.As dental caries, antibacterial can infect dental pulp by cavity, further causes periapical periodontitis, and long-term chronic periapical periodontitis is concatenated to form abscess and just can forms the gingiva fistula; Same periodontal disease also can cause the long-term chronic inflammatory disease of periodontal and periapical tissue, forms the gingiva fistula.The gingiva fistula mainly shows as on the gingiva one or more Semen phaseoli radiati to the swollen thing of Semen Viciae fabae size, swelling repeatedly, suppurates, and long-term disunion, halitosis becomes the long-term chronic infection focus in oral cavity.Treatment for the gingiva fistula, adopt simple root canal over a long period of time, this Therapeutic Method can't be handled periapical and intrafistular chronically infected granulation tissue, therefore gingiva fistula treatment time length, healing are slowly, some tip of a root and furcation area shade the greater, finish root canal backteeth gingival fistula and still can't heal, suppurate odontoseisis in the fistula for a long time.

Summary of the invention

The purpose of this utility model is to overcome the weak point of above-mentioned background technology and a kind of backteeth gingiva fistula curettage instrument is provided, and this curettage instrument can stretch in the fistula up to diseased region from the fistula mouth, thoroughly removes the granulation tissue that infects in diseased region and the fistula.

The purpose of this utility model reaches by following measure: backteeth gingiva fistula curettage instrument, it is characterized in that it comprises handle 1, working head 2, and connect the bending 4 of handle 1 and working head 2; Working head 2 is positioned at the front end of bending 4, and described handle 1 is cylindrical, and there is matsurface 3 at two ends; The length of described working head 2 is 10-20mm, and the diameter of working head 2 transverse section is less than 3mm, greater than 0.3mm; The end face of described working head 2 front ends has pit 5.

In technique scheme, the length of described working head 2 is 20mm.

In technique scheme, the diameter of the transverse section of described working head 2 is less than 2.0mm and greater than 0.3mm.

In technique scheme, the diameter of described handle 1 is 5-6mm, and length is 12cm.

In technique scheme, the angle at α angle is 80-170 ° in the bending 4 of described connection handle 1 and working head 2, and the angle at β angle is 120-180 °.

In technique scheme, angle one end at the α angle in the described bending 4 is 100 °, and the other end is 150 °.

In technique scheme, the end face pit 5 of described working head 2 front ends is oval.

Need to prove: the matsurface at handle two, be mainly and make things convenient for the doctor to control, it can be designed to annular, screw thread etc., and handle can be designed to cylinder also can be designed to regular polygon; Back dental scaler is designed to bending, and the angle of its bending can be designed to the bending angle unanimity at handle two ends, and it is inconsistent also can be designed to handle two ends bending angle, generally is designed to inconsistently for good, so more is useful for different backteeth gingiva fistulas.

Through clinical position for many years, by form to a large amount of gingiva fistulas, length observation is researched and analysed, special this utility model curettage instrument at the design of gingiva fistula, in various fistula treatments, strike off the granulation tissue that infects in the tip of a root, periodontal and the fistula by root canal, periodontal treatment and with this curettage instrument, all obtained excellent curative, various gingiva fistulas all heal; Application by this curettage instrument has been shortened treatment time greatly, has improved cure rate.

Description of drawings

Fig. 1 is gingiva fistula diseased region figure;

Fig. 2 is the structural representation of this utility model backteeth gingiva fistula curettage instrument;

Fig. 3 is the enlarged drawing of this utility model curettage instrument working head two ends end face among Fig. 2.

The specific embodiment

Describe performance of the present utility model in detail below in conjunction with accompanying drawing, but they do not constitute to restriction of the present utility model.

1 is that handle, 2 is that working head, 3 is that matsurface, 4 is that bending, 5 is pit among the figure.

From accompanying drawing as can be known: this utility model backteeth gingiva fistula curettage instrument has handle, working head, bending; Handle can be designed to cylindrical (also can be designed to regular polygon, as regular hexagon etc.) diameter 5-6mm is about and is 12cm, and there is matsurface at handle two, is convenient to the doctor and controls.Back dental scaler working head length will reach 10-20mm, generally is best with 20mm; The rugosity of backteeth gingiva fistula curettage instrument working head is that the diameter of transverse section is less than 3mm, preferably smaller or equal to 2.0mm greater than 0.3mm.The camber of back dental scaler also has certain requirement, and the angle at the α angle of general bending is 80-170 °, and the angle at β angle is 120-180 °; And the angle of two ends bending is also inequality, its objective is the treatment of being convenient to doctor's operation and adapting to the backteeth gingiva fistula of different parts.

It is very easy that backteeth gingiva fistula curettage instrument uses, and under local anaesthesia curettage instrument stretched in the fistula up to diseased region from the fistula mouth, thoroughly removes the granulation tissue that infects in diseased region and the fistula and get final product.

Need to prove that to those of ordinary skill in the art under the prerequisite that does not change this utility model principle, can also carry out some changes or distortion to this utility model, this belongs to protection domain of the present utility model equally.
