Abstract

The invention provides a medical oral dilator. The medical oral dilator comprises a second dilating block, a second supporting plate, a groove, a nut seat, a ball screw, a motor, an illuminating lamp and a gooseneck. The second dilating block is fixed to the lower end face of the second supporting plate which is mounted on the lower end face of the nut seat, the middle of the lower end face of an outer shell is provided with the groove, the nut seat is mounted on the ball screw which is mounted in the middle of the groove, the right end of the ball screw is connected with the motor which is mounted in the middle of the right end face of the outer shell, and accordingly a function of quick positioning of an oral dilating angle is realized, and operations of medical personnel are facilitated. The illuminating lamp is mounted on the lower end face of the gooseneck which is mounted on the front end face of a fixing seat, and accordingly a real-time illuminating angle adjustment function is realized, and examination efficiency of the medical personnel is improved. Therefore, the medical oral dilator has advantages of reasonable structure, functional completeness, convenience in operation, high practicality, high stability and high reliability.

Description

technical field [0001] The invention is a medical oral retractor, which belongs to the technical field of medical instruments. Background technique [0002] Stomatology, one of the classifications of medical disciplines. Major stomatological diseases include: oral and maxillofacial dermoids, epidermal submandibular space infection, maxillofacial lymphangioma, odontoid process malformation, maxillary sinus malignant tumor, jaw bone ameloblastoma, chronic ethmoid sinusitis, Mandibular retrusion, tetracycline teeth, leukoplakia and other diseases. [0003] Because the treatment or operation site in the posterior teeth area is deep, the mouth, tongue and buccal-lingual side of the tooth are closely fitted, the space for treatment or operation is small and difficult to fix, and the necessary distance between the two sides of the tooth cannot be guaranteed at the same time, making the operation easy. Injuries to the tongue mucosa and oral mucosa often require the cooperation of ...

Problems solved by technology

[0003] Because the treatment or operation site in the posterior teeth area is deep, the mouth, tongue and buccal-lingual side of the tooth are closely fitted, the space for treatment or operation is small and difficult to fix, and the necessary distance between the two sides of the tooth cannot be guaranteed at the same time, making the operation easy. Causes damage to the tongue mucosa and oral mucosa, often requires the cooperation of assistants during the operation

[0004] The structure of the oral retractor in the prior art is simple, and the opening angle is not easy to control, and the operation is cumbersome. A kind of medical oral retractor is needed to solve the above-mentioned problems
