Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to an open-type instrument protective cover. Background Art

[0002] During the sterilization process of surgical instruments, some delicate or fragile heads need to be protected. However, when the protective cover is removed after sterilization, adhesion occurs, which will cause human damage, so its structure needs to be changed. After searching the application number CN202222767206.X, it is recorded that the reusable instrument tip protective cover includes wearing it on the head end of a sharp instrument, which can effectively avoid the problem of puncturing the protective cover and exposing the tip. By setting a stretching component, it can be fixed to the instrument to avoid the problem of the protective cover slipping off. The stretching component is detachable and can be installed and used as needed. However, the above description still has the following defects in actual use: the existing instrument end protective cover lacks a buffer fixing structure when in use, and the inner wall is not convenient for direct contact with the end after the protective cover is put in. Therefore, it is necessary to design a practical open-type instrument protective cover. Utility Model Content
