Vitreous cutter capable of facilitating synchronous removal of intraocular foreign bodies for cataract extraction use

Abstract

The invention relates to the technical field of ophthalmic medical equipment, and particularly discloses a vitreous cutter capable of facilitating synchronous removal of intraocular foreign bodies forcataract extraction use. The vitreous cutter capable of facilitating the synchronous removal of the intraocular foreign bodies for the cataract extraction use comprises a cutter main engine; a control panel is arranged on the left side of a front end surface of the cutter main engine; rollers are arranged at all of the four corners of a lower end surface of the cutter main engine; and an adjustment column is veritically mounted on the left side of an upper end surface of the cutter main engine. The vitreous cutter capable of facilitating the synchronous removal of the intraocular foreign bodies for the cataract extraction use has the following beneficial effects: T-shaped sliding splicing is arranged between a beam and the adjustment column so as to realize stable lifting of the beam in cooperation with scale on the adjustment column, thereby clearly and directly reflecting adjusted size so as to make the vitreous cutter adapted to patients of different heights; and moreover, a fork-shaped mounting block is arranged so as to realize gathering of foreign matters and tears, thereby achieving the purpose of fixed-point processing in cooperation with the bearing effect of a bottom plate and the diversion effect of an annular groove so as to make the foreign matters and the tears gathered on the bottom plate. Therefore, the purpose of convenient and accurate experiment is achieved.

Description

technical field [0001] The invention relates to the technical field of ophthalmic medical equipment, in particular to a vitreous cutter for cataract extraction which is convenient for simultaneously removing intraocular foreign bodies. Background technique [0002] For eye surgery such as cataract extraction, it is often necessary to cut and remove the vitreous humor, a clear, jelly-like substance that fills the back segment of the eye. The vitreous humor or vitreous humor is usually made up of a large number of tiny fibers that attach to the retina. Therefore, the vitreous humor The cutting and removal must be done with great care to avoid traction on the retina. [0003] During cataract extraction and removal of vitreous foreign bodies, the eyes will feel sore and cause tears to flow down. Since the probe is thin, when it comes into contact with tears or vitreous foreign bodies, it is easy to block the cutting line of sight. At the same time, when removing foreign bodies, ...

AI Technical Summary

Problems solved by technology

[0003] During cataract extraction and removal of vitreous foreign bodies, the eyes will feel sore and cause tears to flow down. Since the probe is thin, when it comes into contact with tears or vitreous foreign bodies, it is easy to block the cutting line of sight. At the same time, when removing foreign bodies, It is easy to cause damage to the inner membrane of the eye, and the adjustment process of the existing cutter is not stable enough to intuitively reflect the adjustment distance of the height

[0004] To this end, we provide a vitreous cutter for cataract extraction that is convenient for removing foreign bodies in the eye at the same time, so as to solve the problems of foreign body removal, tear management and precise and smooth adjustment.
