Protection mechanism for microscope lens

Abstract

The invention provides a protection mechanism for a microscope lens. The protection mechanism comprises a film and a fixation device for fixing the film. The fixation device comprises a fixed sleeve sleeved on the lens and a movable sleeve sleeved on the fixed sleeve. The film is sleeved on the fixed sleeve. The outer circle of the fixed sleeve is provided with bulge loops. Each bulge loop is internally provided with a clamping hole in the radial direction of the central axis thereof. Each clamping hole is internally provided with an elastic clamping assembly. The inner wall of the movable sleeve is provided with a clamp slot matched with a ball body in the place corresponding to the clamping hole. The circumference wall of the outer circle of the fixed sleeve is annularly provided with acutting slot. The movable sleeve is provided with an installation hole in the place corresponding to the cutting slot. The installation hole is provided with a blade matched with the cutting slot to cut the film and a driving assembly for driving the blade to move back and forth with respect to the axial direction of the installation hole. The protection mechanism is simple in structure, convenient to operate and convenient to take off the film at the front end of the lens for observation.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a protection mechanism for a microscope lens. Background technique [0002] Microscopes used in industrial and medical fields, especially in the field of medical surgery, often require lenses (including eyepieces, objective lenses, etc.) to be in a sterile state so that the lenses will not be polluted when the microscope is used. The existing microscope is also fixed by an elastic ring after the film is sheathed on the lens. This fixing method is not firm, and it is inconvenient to open the film when using a microscope for observation. The cost of the existing protective cover specially used for protecting the microscope lens is high, and the cost of a protective cover is as high as 300 to 400 yuan, which causes economic burden to the patient and is not conducive to the patient's use when seeing a doctor.

AI Technical Summary

Problems solved by technology

Although the medical microscope protective cover can be well fixed on the microscope head, since the cover body set on the microscope head is made of plastic, completely covering the lens may block the line of sight of some lenses (including eyepieces and objective lenses), especially during surgery. , the occlusion of the lens line of sight may seriously affect the smooth progress of the operation. During use, the cover in front of the lens is often cut open with a scalpel to leak the microscope lens, which is inconvenient to operate and easy to scratch the microscope lens.
