Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a special tool for artificial corneal surgery. Background technique [0002] The human cornea is very delicate and an organ that is very easily damaged. Once the damage is difficult to heal itself, it is one of the world's three leading blind eye diseases. Such as trauma, chemical burns, corneal leukoplakia and other lesions are all blind due to severe corneal damage and unable to perform corneal transplantation. Artificial corneas have been developed to restore light to the eyes of the above-mentioned patients. [0003] The artificial cornea in the related art includes a bracket and a mirror column; the bracket extends along a spherical surface, and the center of the bracket is provided with a hole-shaped bracket seat made of medical methyl methacrylate; the inner wall of the bracket seat is provided with internal threads; The radial section of the mirror column i...
