Dental fixed type convenient tooth extraction device

Abstract

The invention discloses a fixed type convenient tooth extraction device for the dental department, and relates to the technical field of medical apparatuses and instruments. Comprising two supporting frames which are symmetrically arranged. A two-way threaded rod is in threaded connection between the two supporting frames; the center position of the bidirectional threaded rod is rotationally connected with a movable guide seat; a main arm is arranged between the opposite faces of the two supporting frames. A first connecting rod is hinged to one end of the main arm; second connecting rods are hinged to the other ends of the first connecting rods; the end part of the second connecting rod is hinged with a meshing end seat; a spring is fixed between the end part of the meshing end seat and the end part of the first connecting rod; the side surface of the other end of the main arm is rotationally connected with a turnover frame; and the main arm is rotationally connected with a side supporting arm through a connecting shaft seat. When a side support arm and a main arm are kneaded, a side push plate turns over to laterally stir buccal muscles of a patient, the side support arm pushes a first connecting rod and a second connecting rod to rotate, and a meshing end seat pushes an overturning frame to rotate, so that the end part of the overturning frame and a clamping end head of a clamping end seat clamp and fix wisdom teeth, and hand malformation caused by long-term use is avoided; and the requirements of actual use are met.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a fixed and convenient tooth extractor for dentistry. Background technique [0002] Tooth extraction is a common technique in dental treatment today. In the practice of tooth extraction, the extraction of wisdom teeth or stubborn caries usually creates a lot of trouble for dentists and patients. Wisdom teeth grow behind the second molars. Due to the lack of space, wisdom teeth are usually in an incorrect position. Coupled with the restriction of the upper and lower jaws, it is difficult to extract wisdom teeth. In addition, many wisdom teeth have not fully grown, and the root and part of the sub-molar Crowns are located in the gums, and under the premise of limited extraction force, it is more difficult to extract wisdom teeth; and stubborn caries are not easy to extract because of the deep roots. [0003] In traditional tooth extraction surgery, one hand usually uses t...

Problems solved by technology

Wisdom teeth grow behind the second molars. Due to the lack of space, wisdom teeth are usually in an incorrect position. Coupled with the restriction of the upper and lower jaws, it is difficult to extract wisdom teeth. In addition, many wisdom teeth have not fully grown, and the root and part of the sub-molar The crowns are located in the gums, and under the premise that the force of tooth extraction is limited, it is more difficult to extract wisdom teeth; and stubborn caries are not easy to extract because of the deep roots of the teeth

[0003] In traditional tooth extraction surgery, one hand usually uses tooth extraction forceps to clamp the wisdom teeth, and the other hand needs to use a spoon to push the patient's buccal muscles apart. Due to the effect of anesthesia, the patient's upper and lower jaws cannot be effectively opened automatically during tooth extraction. , in the process of tooth extraction, it is also necessary to stretch the lower and upper jaws of the patient to avoid blocking the line of sight during tooth extraction. Pressing and opening requires a lot of hand power. When the medical staff uses it for a long time, it is easy to deform the hand and cause great harm to the medical staff. It cannot meet the needs of actual use.
