Apparatus for the fragmentation and aspiration of ocular tissue
摘要
An apparatus for the fragmentation and aspiration of ocular tissues consists of a controlled ultrasonic generator connected to a magnetostriction converter to produce mechanical ultrasonic vibrations transmitted therefrom to a hollow needle joined thereto. The end of the needle opposing the end connected to the magnetostriction converter is adapted to be brought into contact with the ocular tissue under fragmentation and comprises an end wall portion with a through opening having a diameter substantially between 1/3 and 2/3 of the diameter of a needle bore. The surface of the needle can be fashioned into a cone or a cylinder.
