Abstract

A trocar obturator (10) having a removable replaceable tip (12) includes an obturator tip (12) having a sharpened distal end (16), and a first engagement device (22) on its proximal end. An obturator shaft (14) has a second engagement device (32) on its distal end for locking engaging the first engagement device securing the tip, and shaft together. One of the engagement devices borne by one of the tips, and shafts include a flexible member biased to engage the engagement devices.
There are access means (38, 40) for flexing the flexible member against its bias to disengage the engagement devices to release the tip, and shaft.
