Oral cavity opener

Abstract

The invention discloses an oral cavity opener. The oral cavity opener comprises a bent plate, a supporting mechanism is installed on the right side of the bottom of the bent plate, a groove is machined in the left side of the front face of the supporting mechanism, an adjusting mechanism is installed in the groove, a telescopic mechanism is installed on the left side of the top of the supporting mechanism, a through opening is machined in the right side of the front face of the bent plate, and a vertical plate is fixedly connected to the left side of the top of the bent plate. According to theoral cavity opener, the problem that an existing oral cavity opener cannot support a cavity in the oral cavity in use is solved through an air robbing mechanism; the bottom of the oral cavity openeris prevented from abrading the oral cavity; the oral cavity is prevented from being broken during long-time use, troubles are prevented from being caused to a user, the use experience of the user is guaranteed, the problem that the oral cavity cannot be adjusted according to the size of the oral cavity is solved through a telescopic mechanism and a rotating mechanism, the replacement trouble is omitted, time is saved, the working difficulty is reduced, the practicability is improved, functions are comprehensive, and popularization is facilitated.

Description

technical field [0001] The invention relates to the technical field of retractors, in particular to an oral retractor. Background technique [0002] The mouth opener, also known as the mouth opener, is a device used to open the mouth when breathing is difficult or unconsciousness requires gastric lavage, etc. The body of the mouth opener is "U"-shaped, and the two ends of the mouth opener body are fixed respectively. There is a handle, but the existing oral speculum cannot support the cavity in the oral cavity, and it is easy to cause the bottom of the oral speculum to wear the oral cavity, causing oral rupture for a long time, causing trouble to the user, affecting the user experience, and not being able to Oral size adjustment needs to be replaced, which wastes time, increases work difficulty, reduces practicality, and has a single function, which does not meet the needs of modern people.

Problems solved by technology

[0003] The purpose of the present invention is to provide an oral speculum to solve the problem that the existing oral speculum cannot support the cavity in the oral cavity in the above background technology, and it is easy to cause the bottom of the oral speculum to wear the oral cavity, resulting in oral rupture for a long time, which is difficult to use. Or cause trouble, affect the user experience, and can not be adjusted according to the size of the mouth, need to be replaced, waste time, increase the difficulty of work, reduce the practicality, the problem of single function
