Oral-cavity fixing device

Abstract

The invention discloses an oral-cavity fixing device. The oral-cavity fixing device comprises first support rods, a rotary shaft, handles, a first fixing sleeve, fixing parts, a second support rod, first protrusions, a slider, a thin rope, a second fixing sleeve, grooves, first springs, second protrusions, retaining blocks and second spring. The oral-cavity fixing device has the advantages that the grooves are arranged in the top surface of the arc-shaped first fixing sleeve and the bottom surface of the second fixing sleeve, teeth are located in the grooves when the device is used, and the tip of the tongue can be prevented from being bitten by the teeth; the first fixing sleeve and the second fixing sleeve are fixedly connected with the fixing parts, and the fixing parts clamp the handles; when the device is used, the handles are pressed down to compress the springs inside the first support rods to reduce the distance between the fixing sleeves, a person can conveniently bite the grooves, the springs reset when the handles are released to allow the fixing grooves to distract the oral cavity, the first protrusions on the lateral walls of the second support rods are abutted againstthe second protrusions to fix the second support rods so as to fix the oral cavity, the handles are taken out from the fixing parts, and medical equipment can conveniently move inside the oral cavity.

Description

Technical field [0001] The invention relates to a fixing device, in particular an oral fixing device, belonging to the technical field of medical applications. Background technique [0002] The mouth is the starting part of the digestive tract. The front excuse cleft communicates with the outside world, and it continues with the pharynx through the pharyngeal gorge. There are teeth, tongue and other organs in the mouth. The front wall of the oral cavity is the lip, the side wall is the cheek, the top is the palate, and the bottom of the oral cavity is the structure of mucous membrane and muscle. The oral cavity is divided into the anterolateral oral vestibule and the posterior medial proper oral cavity by the upper and lower dental arches; when the upper and mandibular teeth are occluded, the oral cavity and the proper oral cavity can be communicated by the space behind the third molar. During oral treatment, an oral fixation device can be used to open the oral cavity and inse...

Problems solved by technology

[0003] When the oral fixture is put into the oral cavity, it is necessary to use a spreading mechanism to open the oral cavity, and most of the existing spreading mechanisms are located on the outside of the oral fixture. When medical equipment is used to treat the inside of the oral cavity, it is located The expansion mechanism on the outside of the fixture will affect the movement of medical equipment in the mouth and affect the treatment effect; during the use of some oral fixtures, the teeth inside the mouth are easy to bite the tip of the tongue, which is not conducive to the treatment of the mouth
