Crushing tip, intraocular surgical device including the same, cavitation generation suppressing method, and cataract operating method

摘要

Disclosed are a crushing tip, an intraocular surgical device, a cavitation occurrence suppressing method, and a cataract operating method capable of suppressing the occurrence of cavitation. A crushing tip according to the present invention is a crushing tip attached to an intraocular surgical device that applies ultrasonic vibration, and includes a cylindrical support portion attached to the intraocular surgical device, and the support portion. And a cylindrical chip body that communicates with the internal space of the support portion, and the chip body has a length in the first direction that is longer than a length in the second direction perpendicular thereto. The cross section has a shape, and vibration is applied to the support portion so that the chip body reciprocates around the axis of the chip body passing through the centers of the first direction and the second direction.
