Medical adjustable lip opening device

Abstract

The invention discloses a medical adjustable lip opening device. The device comprises an annular base plate, wherein an outer ring body and an inner ring body are concentrically fixed on the base plate; the outer ring body is positioned at the outer ring of the base plate; the diameter of the inner ring body is equal to the average value of the diameters of the inner ring and the outer ring of thebase plate; the inner ring of the outer ring body is provided with an outer groove; the outer ring of the inner ring body is provided with an inner groove; the outer groove and the inner groove are jointly and slidably connected to a plurality of movable blocks; and each movable block is fixedly connected to a plastic rod parallel to the axis of the base plate. The device has the advantages that:in the invention, the lips of a patient are opened by a soft bag, and the pressure of the soft bag to each position of the oral cavity of the patient is equal so as to reduce discomfort; when the opening size is proper, the inner lead is electrified, so that the shapes of the plastic rod and the slide blocks cannot be continuously changed; and in the invention, partial structures such as a rubberhead are arranged, so that the extrusion force of the soft bag to each point is fully ensured to be equal.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a medical adjustable lip stretching device. Background technique [0002] Stomatology, one of the classifications of medical disciplines, the main oral diseases include oral and maxillofacial dermoid, epidermal submandibular space infection, maxillofacial lymphangioma, odontoid process deformity, maxillary sinus malignant tumor, jaw bone enamel Cytoma, chronic ethmoid sinusitis, mandibular retrusion, tetracycline teeth, leukoplakia and other diseases. With current technology, many periodontal diseases can be completely cured. The development of tissue bioengineering technology, such as guided tissue regeneration technology, gene technology, implant denture, etc., brings exciting hope for the regeneration of diseased teeth. [0003] At present, the lip stretching device used in the department of stomatology has poor adjustability and cannot be used by different patients...

AI Technical Summary

Problems solved by technology

[0003] At present, the lip stretching device used in the department of stomatology has poor adjustability and cannot meet the needs of different patients, especially the positions to be treated in the mouth of different patients are different, and the positions of the wounds in the patient's mouth are also different. The opening device is almost non-adjustable. For some patients, it is very easy for the opening device to offset the patient's wound, which will cause unnecessary pain for the patient and seriously affect the treatment effect and the patient's enthusiasm for treatment. Therefore, an easy-to-adjust stomatological lip stretcher
