Abstract

The utility model provides a mandibular fixator, which belongs to the technical field of medical devices. The structure includes a headrest and a backing plate. A chute is arranged on the backing plate in the transverse direction. The bottom ends of the left mandibular support rod and the right mandibular support rod Embedded in the chute and slidingly connected with the backing plate, a headrest is arranged on the plane of the backing plate between the left mandibular strut and the right mandibular strut. The chute adopts a dovetail groove, and the bottom ends of the left mandibular strut and the right mandibular strut are set as dovetail projections. The left mandibular strut and the right mandibular strut of the mandible fixer can fix and support the mandibular angle of the examiner, effectively fix the position of the mandible, maintain a fixed position, prevent it from returning to the position, ensure the effective and error-free progress of medical treatment or inspection, and improve medical quality. The mandibular fixer economically and conveniently solves the problem of maintaining the body position of the examinee, is durable, and has good body position repeatability.

Description

Jaw Immobilizer

technical field

The utility model relates to the technical field of medical instruments, in particular to a jaw fixer.

Background technique

Generally, in head and neck radiation therapy, when the mandibular ramus is perpendicular to the treatment bed, the patient needs to be in an excessively backward head position. Due to the forced position, patients often have involuntary activities, especially when they are fat. Patients with very short necks often lead to poor positioning repeatability. In the past, masks were often used to solve this problem in radiotherapy positioning, but this increased the workload of doctors and nurses and the treatment costs of patients.

Contents of the invention

The technical task of the utility model is to solve the deficiencies of the prior art and provide a jaw fixer.

The technical scheme of the utility model is realized in the following manner. The structure of the mandibular fixer includes a headrest and a backing plate. A chute is opened on the backing plate in the transverse direction. The ends are respectively embedded in the chute and slidably connected with the backing plate, and a headrest is arranged on the plane of the backing plate between the left mandibular strut and the right mandibular strut.

The chute adopts a dovetail groove, and the bottom ends of the left mandibular strut and the right mandibular strut are set as dovetail protrusions.

Compared with the prior art, the utility model has the following beneficial effects:

The left mandibular strut and the right mandibular strut of the mandible fixer can fix and support the mandibular angle of the examiner, effectively fix the position of the mandible, maintain a fixed position, prevent it from returning to the position, ensure the effective and error-free progress of medical treatment or inspection, and improve medical quality. The mandibular fixer economically and conveniently solves the problem of maintaining the body position of the examinee, is durable, and has good body position repeatability.

Reasonable design, simple structure, safe and reliable, easy to use, easy to maintain, etc., therefore, has a very good promotion and use value.
