Patent ID: 8070730

Claim:
A trocar assembly comprising: a trocar valve body defining a cavity, the valve body for communicating insufflation fluid therethrough; and a selectively rotatable valve handle for controlling a flow of said insufflation fluid through the valve body, the rotatable valve handle being elongated and having a first end and a second end, the rotatable valve handle defining a lumen therethrough which extends longitudinally from the first end to the second end to communicate insufflation fluid between the first end and the second end, the first end sized and configured to be rotatably maintained within the cavity and the second end extending outwardly so as to be actuatable by a user; wherein the valve body defines an outlet that communicates with the cavity; wherein the rotatable valve handle is rotatable from an open position, in which the lumen of the rotatable valve handle is at least partially aligned with the outlet so as permit fluid to pass through the lumen, and a closed position, in which the lumen is not aligned with the outlet so as to prevent fluid to pass through the lumen; wherein the rotatable valve handle has at its first end a protuberance that engages a bore defined in the valve body, the protuberance assisting with maintaining the rotatable valve handle within the cavity; wherein one of the bore and the protuberance includes a detent, the other of the bore and the protuberance includes a ridge, the ridge configured to engage the detent so as to maintain the rotatable valve handle in position relative to the valve body.
