Beschreibung
Zusammenfassung:	A trocar has an insertion tube. A tube outlet of the insertion tube communicates with a collar of the insertion tube. An incision blade is provided to the tube outlet. The tube outlet opens toward the incision blade. The incision blade can thereby be inserted into an eyeball to form an incision, and the insertion tube can be inserted in the eyeball through the incision while the incision blade remains in the eyeball. Two lateral blade edges extend from a distal blade edge in the incision blade. The blade edges have outermost blade edges located in an outer region, which is a boundary surface, which includes the inner circumferential surface of the tube outlet. Therefore, the width dimension of the incision blade can be set greater than the inner diameter of the insertion tube.
