Auxiliary bracket for dental examination

Abstract

The invention discloses an auxiliary stent for detection in a stomatology department. The auxiliary stent for detection in the stomatology department comprises a base, a support frame and a distraction part, wherein the distraction part comprises a scissors-shaped distraction rack, an upper distraction tooth socket and a lower distraction tooth socket; the upper distraction tooth socket and the lower distraction tooth socket are fixed on the inner side end of the scissors-shaped distraction rack; the structure of the upper distraction tooth socket is the same as the structure of the lower distraction tooth socket; a wedge-shaped block is arranged at the outer side end of the scissors-shaped distraction rack; a guiding chute is formed in a rack arm at the outer side end of the scissors-shaped distraction rack; guiding sliders which are matched with the guiding chute are separately arranged on the top surface and the bottom surface of the wedge-shaped block; a spring is fixed between anend of the wedge-shaped block and a rotating shaft of the scissors-shaped distraction rack; a positioning clamping tooth is arranged on the surface of the wedge-shaped block; and a convex tooth whichis matched with a positioning slot is arranged on the inner side surface of the scissors-shaped distraction rack. The auxiliary stent for detection in the stomatology department is reasonable in structural arrangement and convenient to operate; the mouth of a patient can be expanded, moreover, normal detection on the throat of the patient is not affected, meanwhile, an expanded part is in a stablestate by the wedge-shaped block under the effect of the spring, and the auxiliary stent for detection in the stomatology department is good in use stability, high in applicability and good in practicability.

Description

technical field

[0001] The invention belongs to the technical field of testing equipment, and in particular relates to an auxiliary bracket for dental testing. Background technique

[0002] The Department of Stomatology mainly involves the treatment and detection of the oral cavity, throat, nasal cavity and ear canal. When detecting the oropharynx, it is necessary to observe through a speculum or external viewing equipment. The traditional technology mainly uses a doctor to hold a speculum and insert it into the oral cavity to complete the inspection. Although it can meet the use requirements to a certain extent, its detection angle needs to be adjusted by doctors and patients, which will affect the detection efficiency and detection accuracy, so the applicability and practicability are limited. Contents of the invention

[0003] The purpose of the present invention is to provide an auxiliary bracket for stomatological testing with reasonable structure and good stability. ...
