Description

Automatic disinfection and sterilization device for surgical instruments

Technical Field

The invention relates to the technical field of automation of surgical instruments, in particular to an automatic disinfection and sterilization device for surgical instruments.

Background

The surgical instruments refer to medical instruments used in clinical operations, and besides conventional surgical instruments, there are some specialized instruments: orthopedics, urology department, gynaecology and obstetrics, burn branch of academic or vocational study, plastic surgery, brain surgery, cardiothoracic surgery, general surgery etc. surgical instruments fall into two main categories in principle: 1. the basic surgical instrument is applied to general and conventional instruments of various clinical departments, and is mainly classified into a knife, a shear, a clamp, a forceps, a drag hook, a retractor and the like; 2. the special surgical instrument is specially used for a surgical instrument of a certain clinical department, for example: oral cavity apparatus, otolaryngology branch of academic or vocational study apparatus, cardiothoracic surgery apparatus, gynaecology and obstetrics/birth control apparatus, orthopedics apparatus, micro-apparatus etc. above surgical instruments can disinfect after using, but tweezers can appear following problem in disinfection and sterilization process:

1. in the disinfection and sterilization process of the traditional tweezers, the tweezers are manually disinfected, when a large number of tweezers need to be disinfected and sterilized, the tweezers can only be manually disinfected and sterilized one by one, so that the required number cannot be reached, the working efficiency is slow, and the required manual labor is large;

2. when the sticky objects on the tweezers which need to be disinfected and sterilized are cleaned, the sticky objects on the tweezers are usually cleaned and then directly fall into the disinfectant in the disinfection tank, so that the disinfectant is not clean and the working quality is low.
