Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a light filtering protection structure used in ophthalmic laser surgery. Background Art

[0002] With the continuous progress and development of science, ophthalmic surgery has entered the era of microsurgery. The use of surgical microscopes not only enables doctors to see the fine structure of the surgical site, but also allows them to perform various microsurgeries that cannot be completed with the naked eye, greatly expanding the scope of surgical treatment and improving surgical precision and patient cure rates. At present, surgical microscopes have become a conventional medical device. Microscopic laser treatment has been deeply developed in the field of ophthalmology because the eyeball itself is an optical system, and light can reach the various layers of tissue of the eyeball through the refractive medium. Fundus disease is a field where lasers are widely used. In addition to diabetic fundus lesions, it is also widely used in retinal vascular lesions, macular lesions, subretinal neovascularization, retinal holes and retinal choroidal tumors, etc. Ophthalmic laser treatment commonly uses 532nm lasers and 1064nm lasers. The above two lasers will cause radiation and stimulation to the eyes. Ophthalmologists need to perform multiple ophthalmic laser surgeries every day. Long-term direct viewing of the laser will cause irreversible damage to the eyes, so special protective glasses are needed to protect the glasses.

[0003] At present, the filtering protection structure used by doctors in ophthalmic laser surgery is usually protective glasses. Such protective glasses can generally only be used alone. In some special environments, goggles are also needed to protect the doctor's eyes. However, the existing filtering protective glasses cannot be used in conjunction with goggles. At the same time, if the lenses of the existing filtering protective glasses are damaged during use, they cannot be quickly disassembled and replaced.
