Mouth holder with adjustable spacing

Abstract

The invention discloses a mouth holder with an adjustable spacing; the mouth holder comprises two bearers symmetrically arranged up and down, an upper tongue plate and a lower tongue plate; one end ofthe upper tongue plate is hinged to the side edge of the upper bearer via a pin shaft 1; one end of the lower tongue plate is hinged to the side edge of the lower bearer via a pin shaft 2; the lowertongue plate is arranged right below the upper tongue plate; an upper lug is fixedly connected in the middle lower part of the upper tongue plate; a lower lug is fixedly connected in the middle upperpart of the lower tongue plate; an adjusting device capable of adjusting length is arranged between the upper lug and the lower lug; the upper and lower bearers are connected via a support device. When a patient is treated with radiotherapy, the mouth holder is placed in the oral cavity of the patient, the patient incisor teeth bite in the bearer grooves, a screw rod is rotated to adjust the distance between the upper and lower tongue plates of the mouth holder, thus fixing the patient tongue, obtaining a better open mouth comfort level, reducing swallowing motion generation, preventing radiotherapy target displacement in radiotherapy, providing more accurate treatment, and obtaining very good clinic usage effects.

Description

technical field [0001] The invention relates to a mouthpiece, in particular to a mouthpiece with adjustable spacing, and belongs to the technical field of medical equipment. Background technique [0002] With the change of human living habits and dietary structure, the incidence of head and neck tumors is increasing year by year, and most of them are locally advanced or even advanced when they see a doctor. It is difficult to achieve the best curative effect with single surgical treatment. Radiation therapy can achieve the best therapeutic effect, and even very early head and neck cancer treatment radiation therapy can achieve the same effect as surgery; radiation therapy is one of the most common treatment methods for head and neck cancer. Due to oral swallowing activities and involuntary tongue movements during radiotherapy, the radiotherapy target area may be shifted, resulting in the possibility of off-target and off-target, and eventually local tumor recurrence and trea...

AI Technical Summary

Problems solved by technology

Due to oral swallowing activities and involuntary tongue movements during radiotherapy, the radiotherapy target area may be shifted, resulting in the possibility of off-target and off-target, eventually leading to local tumor recurrence and treatment failure

In order to avoid the above situation, conventional mouthpieces are often used clinically to reduce oral and tongue movements during treatment; however, conventional mouthpieces are relatively short and difficult to fix the movable part of the entire tongue well, and the fixation repeatability is poor. This is a clinical problem that needs to be solved at present
