Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
Example one
The medical mouth gag shown in fig. 1 comprises a mouth gag body, wherein the mouth gag body comprises a supporting seat 3 and two L-shaped opening arms symmetrically arranged on the supporting seat 3, each opening arm comprises a working part 1 and a hinged part 4 arranged at one end of the working part 1, one end of the hinged part 4, which is far away from the working part 1, is hinged with the supporting seat 3, and an adjusting screw rod 5 which is simultaneously abutted against the hinged parts 4 of the two opening arms is connected with the supporting seat 3 in a threaded manner.
As shown in fig. 1, a working part 1 of the mouth gag body is sleeved with a protective sleeve 2, the protective sleeve 2 comprises a cylindrical elastic sleeve body 21 and an elastic necking ring 22 arranged at an opening of the elastic sleeve body 21, and the working part 1 is provided with a positioning structure for positioning the elastic necking ring 22. In this embodiment, as shown in fig. 5, the elastic necking ring 22 is formed by curling the open end of the elastic sleeve body 21 outwards, and the elastic necking ring 22 and the elastic sleeve body 21 are integrally formed. When the protective sleeve 2 is in the initial state, i.e. when the protective sleeve 2 is not put on the working part 1, the elastic sleeve body 21 is wound on the elastic necking ring 22, the structure of the elastic necking ring is similar to that of a condom when not in use, and the protective sleeve 2 is packaged in a sterile packaging sleeve for being used at any time.
As shown in fig. 2, the positioning structure includes an annular groove 11 formed in the working portion 1, the minimum diameter of the elastic collar 22 is smaller than the outer diameter of the working portion 1, and the elastic collar 22 is located in the annular groove 11. When the elastic shrink-fit sleeve is used, the elastic sleeve body 21 is sleeved on the working part 1, the elastic shrink-fit ring 22 rolls on the working part 1, the elastic sleeve body 21 wound on the elastic shrink-fit ring 22 is gradually released until the elastic shrink-fit ring 22 falls into the annular groove 11, and the elastic shrink-fit ring 22 is tightened in the annular groove 11 under the action of the elastic force of the elastic shrink-fit ring 22.
