Abstract

An embodiment relates to a safety vitreous body cutting device capable of safely removing only a vitreous body attached to a retina without damaging the retina. Here, the safety vitreous body cutting device includes a tubular body part, a cutter part, and a safety net part. The tubular body part is formed in a cylindrical shape, negative pressure is provided at the inside, and an open hole is formed on the outer circumferential surface of a distal end. The cutter part reciprocates along the axial direction of the tubular body part at the inside of the tubular body part to cut the vitreous body introduced into the open hole. The safety net part is provided at the distal end of the tubular body part, and allows the vitreous body to pass through, but prevents the retina tissue from passing through.
