Abstract:
1. A corneal incision system comprising: a corneal incision apparatus for incising a cornea in a layered form, comprising; a blade unit having a blade for corneal incision; and a cutter head unit arranged to hold the blade unit in such a manner as to allow oscillation thereof, the cutter head unit including a first cavity formed with a first opening and arranged to hold the blade unit in such a manner as to allow oscillation thereof; and a blade case arranged to cover and internally store the blade unit, the blade case including a second cavity formed with a second opening and arranged to hold the blade unit and a restriction member for restricting movement of the blade unit within the second cavity, the cutter head unit and the blade case including engagement parts engageable with each other so that, under the condition that the engagements parts are engaged, the first opening and the second opening face and come close in proximity to each other to allow the blade unit to move between the first cavity of the cutter head unit and the second cavity of the blade case, and the blade case including a first push member for exerting insertion pressure for pushing out the blade unit held in the second cavity through the second opening against movement restriction by the restriction member in order to slide the blade unit in a lateral direction of the blade and push the blade unit out of the second cavity into the first cavity through the second opening and the first opening, the first push member being integrally held in a first straight guide of the blade case in such a manner as to be movable forward and backward in only a pushing direction, the first straight guide extending to the vicinity of the second opening, and the first push member being connected to a first operating part to be operated by operator's fingers, wherein the first push member slides the blade unit in an opposite lateral direction of the blade to pull the blade out of the first cavity and return it into the second cavity through the first opening and the second opening.
