    • PROBLEM TO BE SOLVED: To eliminate the fear of hooking a bladder rear part at the time of an operation by forming a comparatively soft tube-shaped cap for sealing the distal end of a canula which is connected to a hub in a proximal end and opened in the distal end in a sucking chip to be used in the crystal lens ultrasonic suction operation of eyes. SOLUTION: The sucking chip 10 consists of the canula 12 and the cap 14. The canula 12 is opened in the distal end 18 and connected to the hub 16 in the proximal end 22 and the sucking chip 10 is connected to proper parts for a hand in the hub 16. The canula 12 and the hub 16 are preferably made from a titanium or stainless steel but the cap 14 where the distal end 18 is sealed is preferably formed from comparatively soft rubber or plastic, for example, silicone rubber or an acrylic material. It is provided with an almost tube-shape, opened in the proximal end 24 and formed to be the shape where the distal end 26 is closed except a mouth 20.
