Abstract

The utility model relates to an ophthalmology medical instrument field specifically is a cambered surface cornea laser confocal microscope safety cover, including the safety cover body, the one end of safety cover body is installed on cornea laser confocal microscope, and the other end contacts with the eyeball, and is provided with the arc concave surface on the face with the eyeball contact. The radius of curvature of the curved concave surface is the same as the radius of curvature of the corneal surface. The shape of safety cover body is the bowl form of hemisphere, and the lower part is wide to have the draw-in groove of card on the confocal microscope lens of laser. The utility model discloses an arc surface cornea laser confocal microscope safety cover of design is the arc surface with the preceding terminal surface of cornea contact, when cornea laser confocal microscope safety cover and cornea surface contact, because arc surface curvature radius is the same with cornea surface curvature radius, just can flatten the cornea surface, and unlikely to cause the injury to the cornea surface. Solves the problem that the protective cover in the prior art can cause corneal deformation and even damage to the cornea when in use.

Description

Cambered surface cornea laser confocal microscope safety cover

Technical Field

The utility model relates to an ophthalmology medical instrument field specifically is a cambered surface cornea laser confocal microscope safety cover.

Background

The cornea laser confocal microscope is used for observing the tissue structure and cell morphology of the cornea periphery and the central cornea of a normal human eye by utilizing a laser confocal microscope technology, the technology is accurate, rapid and nondestructive, and the technology is rapidly applied and developed in recent years. Because the front end of the microscope needs to be in direct contact with the surface of the cornea, a disposable protective cover of the corneal laser confocal microscope is needed, and each patient can be ensured to be used independently and not to be cross-infected with each other.

The contact front end of the existing cornea laser confocal microscope protective cover and the cornea is plane, and the measurement can be carried out only by flattening the surface of the cornea. Because the surface of the cornea is curved, the protective cover is flat, and flattening can result in deformation of the cornea and even damage to the cornea. Therefore, a cambered surface cornea laser confocal microscope protective cover is provided.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cambered surface cornea laser confocal microscope safety cover possesses and avoids haring the cornea, does not influence normal measuring advantage, has solved prior art's safety cover and can lead to the cornea to warp when using, leads to the problem of damage to the cornea even.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an cambered surface cornea laser confocal microscope safety cover, includes the safety cover body, the one end of safety cover body is installed on cornea laser confocal microscope, and the other end contacts with the eyeball, and is provided with the arc concave surface on the face that contacts with the eyeball.

Preferably, the radius of curvature of the arcuate concave surface is the same as the radius of curvature of the corneal surface.

Preferably, the curvature radius of the arc concave surface is 24-27 mm.

Preferably, the protective cover body is made of PC material.

Preferably, the protective cover body is colorless and transparent.

Preferably, the shape of the protection cover body is a hemispherical bowl shape, the lower part of the protection cover body is wide, and the protection cover body is provided with a clamping groove clamped on a lens of the laser confocal microscope.

Compared with the prior art, the beneficial effects of the utility model are as follows:

the cambered surface cornea laser confocal microscope protective cover is cambered through the designed front end surface of the contact with the cornea, when the cornea laser confocal microscope protective cover is in contact with the surface of the cornea, because the cambered surface curvature radius is the same as the corneal surface curvature radius, the corneal surface can be exactly flattened, and the injury to the corneal surface can not be caused. Solves the problem that the protective cover in the prior art can cause corneal deformation and even damage to the cornea when in use.

Drawings

FIG. 1 is a schematic view of a protective cover of a conventional corneal laser confocal microscope;

fig. 2 is a schematic structural diagram of the present invention.

In the figure: 1. a protective cover body; 2. an arc-shaped concave surface.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the lower bayonet of the conventional corneal laser confocal microscope protective cover is similar to our product, but the end surface of the upper part contacting with the cornea is horizontal and cannot form a complete fit with the surface of the cornea.

Referring to fig. 2, a protective cover for a corneal laser confocal microscope with an arc surface comprises a protective cover body 1, one end of the protective cover body 1 is installed on the corneal laser confocal microscope, the other end of the protective cover body is in contact with an eyeball, and an arc concave surface 2 is arranged on the surface of the protective cover body in contact with the eyeball. The arc-shaped concave surface 2 is polished to be flat and smooth, and does not cause damage to the cornea of the human eye. Because the design is simple, the lower surface mould of the protective cover of the corneal laser confocal microscope is directly opened into an arc surface. Because the precision die is used for production, the cost is low, the process is simple, and mass production can be realized.

The radius of curvature of the curved concave surface 2 is the same as the radius of curvature of the corneal surface. Because the radius of the arc concave surface 2 of the protective cover of the corneal laser confocal microscope is almost the same as that of the curved surface of the cornea, the surface is polished, flat and smooth, and can be well attached to the surface of the cornea, and the surface of the cornea can be well protected when being pressed down without damaging the surface of the cornea.

The curvature radius of the arc concave surface 2 is 24-27 mm. Specifically, the radius of curvature is 24mm, 24.5mm, 25mm, 25.5mm, 26mm, 26.5mm and 27 mm.

The protective cover body 1 is made of a PC material and is colorless and transparent. The protective cover body 1 is shaped like a hemisphere bowl, the lower part of the protective cover body is wide, and a clamping groove clamped on a lens of the laser confocal microscope is formed. The product is disposable, sterilized before use, and aseptically packaged. Can ensure the cleanness and sanitation of the surface of the cornea, has no pollution and does not mutually infect.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
