Medical mouth opener

Abstract

The invention relates to the technical field of medical apparatuses and instruments, in particular to a medical mouth opener. The medical mouth opener comprises two dentures, a telescoping rod and a tongue pressing plate, wherein the telescoping rod consists of a first fixing part, a second fixing part and a telescoping part, a sliding groove is formed in the first fixing part, one end of the telescoping part is accommodated in the sliding groove and is in sliding connection with the first fixing part through the sliding groove, and the other end of the telescoping part is connected with the second fixing part. An electric push rod is installed in the sliding groove and connected with the telescoping part and drives the telescoping part to perform telescoping motion. When the telescoping part contracts, the first fixing part is mutually in contact with the second fixing part. The two dentures are of U-shaped structure and are connected with the first fixing part and the second fixing part respectively, and the sides, facing the telescopic part, of U-shaped openings of the two dentures are opposite. One end of the tongue pressing plate is connected with the second fixing part, and the tongue pressing plate and the telescopic part form an angle of 90-95 degrees. The medical mouth opener is simple in structure, environmentally friendly, safe and convenient to use and has automatic telescoping, illumination and sterilization functions.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of medical instruments, in particular to a medical gag. [0003] 【Background technique】 [0004] As we all know, there are many kinds of oral diseases, and teeth, throat, upper and lower jaws, etc. are all prone to lesions, which not only cause damage to teeth, gums, pulp, etc., but also affect the development of the jaw bone, forming a systemic disease. disease. Because medical institutions need to use gags to open the patient's mouth in clinical diagnosis and treatment of various diseases of the oral cavity, especially when performing various operations, such as operations on the throat, upper and lower jaws, because the operation time is longer, so There is a need for a medical gag that is stable in support, does not affect the doctor's line of sight, and is easy to operate and easy to use.

Problems solved by technology

Because medical institutions need to use gags to open the patient's mouth in clinical diagnosis and treatment of various diseases of the oral cavity, especially when performing various operations, such as operations on the throat, upper and lower jaws, because the operation time is longer, so There is a need for a medical gag that is stable in support, does not affect the doctor's line of sight, and is easy to operate and easy to use. In the prior art, some gags are composed of an upper support frame and a lower support frame, and there is a gap between the upper support frame and the lower support frame. Provided with a support body, the upper and lower support frames are often too large to easily block the doctor's sight, and the design is cumbersome, troublesome to use, and it is inconvenient to remove the upper and lower support frames from the teeth; moreover, for oral treatment Medical devices, which attach great importance to disinfection, improper disinfection may cause cross-infection, so in oral medical devices, disposable products are better; however, generally, oral medical devices with upper and lower support frames cannot be used twice after being used once. Use, this method is a waste of materials, so the use of disposable materials should be reduced and the recycling of dental medical devices should be promoted

In addition, in the treatment of the oral cavity, doctors often use lighting to illuminate the affected part of the patient, which causes great inconvenience to the doctor during the treatment process.
