Embodiment Construction

[0097] see Figure 1A , 1B One embodiment of the disclosed trocar assembly, generally indicated at 10 , may include a sleeve assembly 12 and a plug assembly 14 . Optionally, as will be discussed in more detail below, trocar assembly 10 may additionally include an insufflation valve assembly 16 coupled to sleeve assembly 12 .

[0098] The sleeve assembly 12 may include a generally cylindrical or tubular cannula 18 , a generally annular housing 20 , a passage seal 50 received in the housing 20 , and a cap 56 attached to the housing 20 . Cannula 18 may be elongated along longitudinal axis A and may include an open proximal end 22 and an open distal end 24 . Open distal end 24 may include a bevel 26 terminating in a pointed tip 27 . Lumen 28 ( Figure 1C ) may extend along the axial length of the cannula 18 between the open proximal end 22 and the open distal end 24. Housing 20 may define an interior volume 30 and may include an open proximal end 32 and an open distal end 34 ....

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.

Description

technical field [0001] This patent application relates generally to surgical devices and procedures, and more particularly, this patent application relates to trocar assemblies for surgical procedures. Background technique [0002] The trocar assembly typically includes a plug that extends through the elongated working channel of the sleeve such that the piercing end of the plug extends beyond the distal end of the cannula. During a surgical procedure (eg, laparoscopic surgery), the piercing end of the plug is advanced through the patient's abdominal wall until the trocar assembly is extended into the abdominal cavity. A viewing device can be used to provide visual feedback during the insertion step. Once the trocar has been positioned as desired, the plug is removed from the sleeve, thereby providing the physician with small access to the patient's abdominal cavity. [0003] Typically, an insufflation fluid, such as carbon dioxide gas, is fed through the sleeve of the tro...
