Abstract

A more navigable trocar includes an elongated curved shaft having a proximal end adapted for attachment to a drainage tube and a sharpened distal tip, and one or more recess pads closer to the proximal end, facilitating a more predictable grasping and manipulation to steer the trocar through a body. A pair of spaced-apart recess pads may be used, and they may be angled relative to one another to accommodate use of either hand by a surgeon. A different preferred embodiment includes a protective cap for a trocar comprising a polymeric or elastomeric material including a central portion, enabling the sharpened tip of the trocar to pierce and penetrate therethrough with the cap remaining outside the body. This embodiment may be used with or without the recess pad(s). The cap may further include a flattened distal end to stabilize and reduce movement as the tip of the trocar is pushed through the cap.
