Abstract
A trocar assembly including a sleeve assembly defining a working channel extending axially therethrough and including an insufflation port in fluid communication with the working channel, and an insufflation valve assembly fluidly coupled to the insufflation port, the insufflation valve assembly including a valve member and a housing, wherein the valve member defines an inlet channel and is biased relative to the housing to a first position in which the inlet channel is in fluid communication with the working channel, and wherein the valve member is moveable relative to the housing from the first position to a second position in which the inlet channel is fluidly decoupled from the working channel.

A trocar assembly comprising:
- a sleeve assembly defining a working channel extending axially therethrough and including an insufflation port in fluid communication with said working channel;
- and
- an insufflation valve assembly fluidly coupled to said insufflation port, said insufflation valve assembly including a valve member and a housing, wherein said valve member defines an inlet channel and is biased relative to said housing to a first position in which said inlet channel is in fluid communication with said working channel, and wherein said valve member is moveable relative to said housing from said first position to a second position in which said inlet channel is fluidly decoupled from said working channel.
A trocar assembly comprising:
- a sleeve assembly defining a working channel extending axially therethrough and including an insufflation port in fluid communication with said working channel;
- and
- an insufflation valve assembly fluidly coupled to said insufflation port, said insufflation valve assembly including a valve member and a housing, wherein said housing defines at least one vent opening, and wherein said valve member defines an inlet channel and is biased relative to said housing to a first position in which said inlet channel is fluidly coupled with said working channel and said working channel is fluidly decoupled from said vent opening, and wherein said valve member is moveable relative to said housing from said first position to a second position in which said inlet channel is fluidly decoupled from said working channel and said working channel is fluidly coupled with said vent opening.
