Abstract

A crushing tip dramatically increases a contact area between the crushing tip ultrasonic vibrated and a crystalline lens, compared to conventional crushing tips, and can efficiently crush and emulsify the crystalline lens. In the crushing tip, which is inserted into the crystalline lens of an eye of a patient at a time of an eye surgery for crushing, sucking, and discharging the crystalline lens by providing the ultrasonic vibrations, one or a plurality of partition walls is provided in such a way as to cross a through hole inside the through hole of a cylindrical tip main member. A tip of the partition wall may project from a tip of the tip main member, and a projecting portion may extend to an outer peripheral edge of the tip main member in a width direction as well.

Claims

1. A crushing tip for an eye surgery, which is adapted to be inserted into a crystalline lens of an eye of a patient at a time of an eye surgery for crushing, sucking, and discharging the crystalline lens by providing ultrasonic vibrations, comprising:

a cylindrical tip main member having a through hole; and

one or a plurality of partition walls provided in such a way as to cross the through hole of the tip main member.

2. A crushing tip for an eye surgery according to claim 1, wherein the tip main member is formed in a straight shape in a transmitting axial line direction of the ultrasonic vibrations.

3. A crushing tip for an eye surgery according to claim 1, wherein at least a portion of the tip main member, which is adapted to be inserted into the crystalline lens, is formed in a circular shape or an oval shape in cross section.

4. A crushing tip for an eye surgery according to claim 1, wherein a tip of the partition wall projects from a tip of the tip main member.

5. A crushing tip for an eye surgery according to claim 4, wherein the tip of the partition wall projecting from the tip of the tip main member extends to an outer peripheral edge of the tip main member in a width direction.

6. A crushing tip for an eye surgery according to claim 1, wherein the plurality of partition walls is intersected.

7. A crushing tip for an eye surgery according to claim 1, wherein the plurality of partition walls is provided in parallel.
