Abstract:
A coupling system is provided for connecting a tube set to a trocar that includes a multi-lumen trocar having a housing that includes a connector, wherein the connector has a plurality of coaxial flow passages defined therein by a plurality of concentric annular walls, a multi-lumen tube set including a plurality of tubes arranged in a parallel relationship, and a coupling including a generally cylindrical body having a first end portion configured to selectively mate with the coaxial flow passages of the connector of the trocar and a second end portion configured for attachment to the parallel tubes of the tube set.
Abstract:
A surgical instrument adapted and configured for use in minimally invasive surgical procedures includes a shaft, an end effector and a proximal handle. The longitudinal shaft has proximal and distal end portions, and defines a longitudinal axis of the surgical instrument. The distal end effector is connected to the distal end portion of the shaft, and is adapted and configured for performing a surgical task. The proximal handle portion is operably connected to the proximal end portion of the longitudinal shaft and has an actuatable portion operably connected to the end effector to result in movement of the end effector. The distal end portion of the shaft can be laterally offset from the longitudinal axis of the shaft and/or have one or more bends or curves formed therein. The proximal portion of the shaft can include at least one bend to allow for comfortable positioning of a surgeon's hands.
Abstract:
An insufflation and smoke evacuation system for use during laparoscopic surgical procedures in an abdominal cavity of a patient is disclosed that includes a pump for circulating pressurized gas within the system, and a dual lumen cannula configured to provide access to the abdominal cavity of a patient, which includes a first lumen communicating with a source of insufflation fluid and a second lumen communicating with the pump.
Abstract:
A surgical gas delivery system is disclosed that includes a device housing supporting a control unit and a filter interface having a seat for receiving a filter cartridge, the filter cartridge having a filter housing defining an interior reservoir, wherein sensors are coupled to the control unit for sensing a level of liquid within the reservoir of the filter cartridge to prevent contamination of the device, and wherein a set of blocking valves are provided in the device housing for interacting with the filter cartridge when it is received in the filter interface to control flow through suction and pressure lines of the device, and wherein the control unit is adapted to recognize a characteristic of the filter cartridge received in the filter interface.
Abstract:
A valve assembly and method are provided for selectively controlling a flow of pressurized fluid from a fluid source to trocar assemblies. The valve assembly includes a first coupling configured and adapted to couple to a primary trocar assembly for directing pressurized fluid thereto, a second coupling configured and adapted to couple to a secondary trocar assembly for directing pressurized fluid thereto, a third coupling configured and adapted to couple to a source of pressurized fluid for directing pressurized fluid from the source to the first and second couplings; and at least one valve member adapted and configured to be operable in at least first and second operating positions, wherein (i) the first operating position directs pressurized fluid from the source to a coupled primary trocar assembly while preventing pressurized fluid from the source from flowing to at least a coupled secondary trocar assembly, and (ii) the second operating position directs pressurized fluid from the source to the coupled primary trocar assembly and to at least the coupled secondary trocar assembly.

Abstract:
Systems for insufflation and recirculation of insufflation fluid in a surgical procedure include a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The pressure-controlled valve is in fluid communication with an insufflation gas supply, the supply conduit and the return conduit and is adapted and configured to respond to pressure control signals to adjust position and thereby system flow parameters, to reduce entrainment of air from the surrounding environment, and to increase the concentration of insufflation gas in an operative space, and/or to reduce an overpressure condition in the operative space.
Abstract:
An access device adapted and configured to be inserted through a natural biological orifice, and related surgical methods are provided. The access device includes a body, a nozzle means and means for delivering a pressurized flow of fluid to the nozzle means. The body is configured and dimensioned to be inserted through a natural bodily orifice and has proximal and distal end portions and defines at least one lumen therethrough to accommodate passage of one or more surgical instruments. The nozzle means is operatively associated with the body for directing pressurized fluid into the lumen to develop a pressure differential in an area within a region within the lumen to form a fluid seal around the one or more surgical instruments passing therethrough.
Abstract:
The present invention relates to surgical access devices (or surgical access ports) and related methods. More particularly, the present invention relates to such devices that are advantageously adapted for use in single-incision laparoscopic surgical (“SILS”) procedures The present invention also relates to kits and methods involving such surgical access devices.
Abstract:
A surgical instrument for use in laparoscopic surgical procedures is disclosed that includes an elongated shaped outer shaft having opposed proximal and distal end portions, and having a non-circular cross-sectional profile, an end effector operatively associated with a distal end portion of the shaped outer shaft and including a pair of cooperating jaw members configured for movement between open and closed positions, a proximal handle assembly operatively associated with a proximal end portion of the shaped outer shaft and including a pivoting actuation handle, and an elongated actuation member extending through the shaped outer shaft from the proximal handle assembly to the end effector, whereby movement of the actuation handle causes corresponding movement of the cooperating jaw members.
