Hard lens protection sleeve

Abstract

The invention relates to a hard lens protection sleeve, which comprises a hard sleeve for protecting a hard video lens and a soft bag sleeve for protecting a video transmission line. The front end ofthe hard sleeve is a straight sleeve while the rear part of the hard sleeve is an operation sleeve; the operation sleeve is provided with a soft film area, and the operation sleeve and the straight sleeve are mutually embedded in each other and can rotate coaxially so that an operation button of the hard video lens operates normally. Double films capable of water injection and arranged at the headof the hard sleeve can enlarge a camera. A heating ring can prevent lens from fogging. A multifunctional inflatable tube can prevent fogging and is used as an operation chamber. A cleaning mechanismcan clean the head. The soft bag sleeve and the operation sleeve are connected in a seal mode and can be arranged to sleeve a hard video lens video rod and a video transmission lead to avoid damage caused by repeated disinfection to the hard video lens video rod and the video transmission lead, improve the use efficiency of the hard video lens video rod and the video transmission lead, and reducethe use cost. The hard lens protection sleeve has a simple structure and high practicability.

Description

technical field [0001] The invention relates to a sleeve bag, in particular to a hard mirror protective sleeve, which belongs to the technical field of medical instruments. Background technique [0002] At present, when performing some cavity examinations and operations, it is necessary to use rigid videoscopes, and the rigid videoscopes include laparoscopy videoscopes, hysteroscopy videoscopes, rigid bronchoscopes, urethral videoscopes and the like. With the development of science and technology, the new generation of video mirrors has higher and higher pixels, and the imaging effect is getting better and better. The high-quality hard video mirror can enlarge the field of view, allowing doctors to observe the field of view of surgery or inspection more clearly, and is very popular among doctors. However, these hard video mirrors are expensive, costing hundreds of thousands or even millions, and the number of hospitals buying them is limited, which affects doctors' demand f...
