Surgical trocar having obturator handle with flexible contact portion
First Claim
1. An obturator assembly comprising:
- a handle having an opening therein and a flexible contact portion, said flexible contact portion being outwardly deflectable from said handle;
an obturator shaft extending through said handle opening and having a proximal end fixed to said handle and a distal end having a penetrating tip thereon;
a protector slidably disposed around said obturator shaft and also extending through said handle opening for covering said penetrating tip of said obturator shaft, said protector having an aperture at a distal end thereof for permitting said penetrating tip of said obturator shaft to pass therethrough, said protector also having a proximal end movable against said flexible contact portion of said handle to a retracted position in order to expose said penetrating tip when a proximal force is placed against said protector.

Abstract
A surgical trocar has a cannula assembly including a sleeve having a proximal end, a distal end and a passageway therethrough. A housing having an opening is located at the proximal end of the sleeve and is aligned with the passageway of the sleeve. The trocar also includes an obturator assembly which is insertable in the cannula assembly. The obturator assembly includes a handle having an opening therein and a flexible contact portion which is outwardly deflectable from the handle. The obturator assembly also includes an obturator having a proximal end connected to the handle and a distal end opposite the proximal end. A penetrating tip is located at the shaft distal end for penetrating tissue. A protector having a distal end is slidably disposed around the obturator shaft for covering the penetrating tip. The protector has an aperture at its distal end for permitting the penetrating tip to pass therethrough. The protector proximal end is movable against the flexible contact portion of the obturator handle to expose the penetrating tip when a proximal force is asserted against the protector.
