Problems solved by technology

[0004] First, because the tooth-extracting pliers are used to extract teeth, the tooth-extracting forceps are tightly gripped so that the tooth-extracting forceps can clamp the affected tooth, and then the tooth-extracting forceps are pulled out hard, and the operation is improper during the extraction, and the clamping is not good. The loose tooth is detached, and the tooth extraction forceps move upward due to the large inertia, which will hurt the upper jaw of the oral cavity;
[0005] Second, since the tooth extracting pliers are pulled up manually, there is a problem that it is very laborious and difficult to master during operation

Embodiment Construction

[0024] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0025] see Figure 1-3 , an automatic tooth extraction instrument, which includes a tooth clamping mechanism 1 and a tooth extraction mechanism 2.

[0026] see Figure 4-7 , wherein, the clamping mechanism 1 includes a first clamping arm 1-1, a second clamping arm 1-2, a hinge shaft 1-3, an arc-shaped external rack 1-4 and a locking plate 1-5.

[0027] The first clamping arm 1-1 and the second clamping arm 1-2 are symmetrically crossed, and the middle part of the first clamping arm 1-1 and the middle part of the second clamping arm 1-2 are hinged by the hinge shaft 1-3. In this way, the two side sections of the first clamping arm 1-1 are respectively the front section and the rear section, and the two side sections of the second clamping arm 1-2 are respectively the front section and the rear section.

[0028] The upper end of the hinge shaft 1-3 is provid...

Abstract

The invention discloses an automatic tooth extraction device, which is characterized in that it comprises a tooth clamping mechanism (1) and a tooth extraction mechanism (2); the tooth clamping mechanism (1) comprises a first clamping arm (1-1), a second clamping arm Arm (1-2), hinge shaft (1-3), arc-shaped external rack (1-4) and locking plate (1-5); the extraction mechanism (2) includes a fixed arm (2-1) , two lateral tooth pressure blocks (2‑2), two pull cords (2‑3), guide wheels (2‑4) and electric cylinders (2‑5). The invention can realize automatic tooth extraction and has safe operation.

Description

technical field [0001] The invention relates to an automatic tooth extraction instrument. Background technique [0002] At present, in the medical process of stomatology, it is often necessary to extract the affected tooth or loose teeth, and the tooth extraction operation will be completed by means of tooth extraction forceps. [0003] However, when using tooth extractors to extract teeth, there are following deficiencies in operation and are analyzed as follows: [0004] First, because the tooth-extracting pliers are used to extract teeth, the tooth-extracting forceps are tightly gripped so that the tooth-extracting forceps can clamp the affected tooth, and then the tooth-extracting forceps are pulled out hard, and the operation is improper during the extraction, and the clamping is not good. The loose tooth is detached, and the tooth extraction forceps move upward due to the large inertia, which will hurt the upper jaw of the oral cavity; [0005] Second, because the to...
