| titleOfInvention | Fixed depth corneal marker trephine |
| abstract | The invention relates to a fixed-depth corneal marker trephine and an operation method thereof. The lower end of the marking part is provided with raised marking lines evenly distributed along the circumferential direction and extending radially. When nesting, the central axis of the marking line coincides with the central axis of the blade of the knife part, the upper end face of the marking part contacts the lower end of the finger support part of the knife part, and the blade of the knife part protrudes from the inner side of the marking part of the marking part to a predetermined cutting depth. When using a fixed-depth corneal marker trephine to cut the recipient cornea, after the cutting depth reaches the predetermined cutting depth, the blade of the knife cannot continue to cut down, so that the cornea can be cut at a uniform depth. At the same time, the corneal circumcision center is coaxial with the corneal marking line, which makes the operation safer and more precise. |
