Description
Technical field
The invention belongs to medical supplies, in particular to a kind of minimally invasive endoscope protection auxiliary device.
Background technique
Currently, clinical Minimally Invasive Surgery endoscope, gos deep into patient's lesion cavity, sight glass head and inserted link in art, stick trouble
Person's body fluid and removing tissue, have a large amount of pathogenic microorganisms.Multiple tracks liquidation procedures, such as cleaning, sterilizing are needed after endoscope operation.
Structure is complicated for endoscope head, has camera lens, lighting source, more pieces, therefore, cleaning are difficult, and have many cleanings
Dead angle is not easy clear clean.In addition, beaing in the process of cleaning, scratching be easy to cause damage to endoscope lens.
Without clearly boundary, handle has the precisions such as eyepiece, regulating system, output optical cable for endoscope inserted link and control handle
System cannot be cleaned, otherwise functions of the equipments be easy to cause to fail.Unwashed handle can inversely infect inserted link, this will cause
Cleaning be not thorough, cross-infection.
If endoscope continues to sterilize, the factors such as temperature, gas, ray of different sterilization methods can cause sight glass non-pre-
Phase damage, shortens the sight glass service life.
Sight glass cleans multiprogramming, including time-consuming, labor intensive, use cost is significantly increased, influences device for disassembly process
Tool utilization rate.
Sight glass repeated washing may cause microorganism and develop drug resistance to disinfectant, reduce cleaning effect, causes to intersect and feel
Dye.
Disinfectant removal in cleaning process is not thorough, and can be entered patient's body, be also resulted in unexpected adverse effect.
Hospital-acquired infection caused by the disinfection of sight glass and sight glass is easy to be ignored by doctor.
Summary of the invention
It is an object of the invention to overcome above-mentioned defect, a kind of minimally invasive endoscope protection auxiliary device, the dress are provided
