Abstract

An ophthalmic monocular handheld digital microscope with a slit lamp mainly resolves problems that a slit light spot size adjusting mechanism of an existing monocular handheld microscope with a slit lamp is complex, and processing and assembly are inconvenient. The ophthalmic monocular handheld digital microscope is characterized in that at least one pin (6) is fixed on the outer wall of a projecting mirror (8), a strip-shaped guiding groove (17) is axially arranged on a side wall of a fixing sleeve (12), a first adjusting knob (18) is disposed outside the fixing sleeve (12), a spiral groove (19) is arranged on the inner wall of the first adjusting knob (18), each pin (16) penetrates through the guiding groove (17), and an end of each pin (16) is placed in the spiral groove (19) of the first adjusting knob (18). The ophthalmic monocular handheld digital microscope has the advantages of light weight, simple structure and convenience in adjustment of sizes of slit light spots, further can record digital images, can adjust the directions of the slit light spots and switch different filter discs, and can be flexibly and conveniently used by doctors.

Description

technical field [0001] The invention relates to a medical slit lamp microscope, in particular to a monocular hand-held digital slit lamp microscope for ophthalmology. Background technique [0002] The slit lamp microscope is the most commonly used inspection equipment in ophthalmology. The slit lamp microscope is divided into a desktop slit lamp microscope and a hand-held slit lamp microscope. The hand-held slit lamp microscope is easy to carry around, and it is also convenient for examining patients in the lying position. There are two types of handheld slit lamp microscopes: binocular handheld slit lamp microscope and monocular handheld slit lamp microscope. The existing monocular handheld slit lamp microscope includes a light source device and a microscope device. The light source device is composed of a switch, a power supply, a light source, a light collecting mirror, a slit glass, a projection mirror and a reflector. The switch is installed at one end of the housing. ...
