Expander for dental restoration department

Abstract

The invention provides a dilator for the dental restoration department, and relates to the technical field of medical auxiliary instruments, the dilator comprises a seat body, a support part, a disinfection part and an auxiliary part; the seat body is of a concave structure; the supporting part is composed of two sliding rods, a supporting arm, an adjusting rod, a handle, a protrusion A, a clamping groove, a contact block, a protrusion B, a groove, an auxiliary plate and a wiping block. Due to the fact that each supporting arm is provided with one contact block, the contact blocks make contact with the oral cavity in the using process, and the contact blocks are rotationally connected with the supporting arms, the positions of the base body and the supporting arms can be adjusted through rotation between the contact blocks and the supporting arms, the oral cavity is prevented from being blocked, and the problems that firstly, the contact blocks are in contact with the oral cavity are solved. Although an existing device can open the oral cavity, the oral cavity is shielded greatly after the device is opened, and therefore convenience of oral cavity restoration is affected. Secondly, the problem that an existing device cannot achieve oral cavity disinfection while opening the oral cavity is solved.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a spreader used in dental prosthetics. Background technique [0002] In the process of examining the inside of the oral cavity, in order to facilitate the inspection, the mouth needs to be opened to avoid the inconvenience of the patient's mouth being closed, so it is generally necessary to use oral expansion tools, which are also one of the more common tools in stomatology. one. [0003] However, as far as the current traditional dental prosthetic expander is concerned, first of all, although the existing device can open the oral cavity, it shields the oral cavity too much after the expansion, thus affecting the convenience of oral restoration; secondly, the existing device Can not realize the disinfection of oral cavity while propping up oral cavity. Contents of the invention [0004] In view of this, the present invention provides a spreader for prostho...
