A coupling system is disclosed for connecting a tube set to a trocar that includes a multi-lumen trocar having a housing that has a connector extending outwardly from the housing, the connector having 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, a coupling including a generally cylindrical body having a first end portion adapted and configured to selectively mate with the coaxial flow passages of the connector of the trocar and a second end portion adapted and configured for attachment to the parallel tubes of the tube set, and a latch assembly operatively associated with the cylindrical body of the coupling for selectively engaging the connector of the trocar housing when the coupling mates with the connector.

Coupling devices for tube sets used with surgical gas delivery systems

The various embodiments disclosed herein relate to arms or forearms of medical devices that are configured to couple with quick-release end effectors, quick-release end effectors for use with such medical devices, and arms or forearms coupled to such quick-release end effectors. Certain forearms and end effectors have magnetic couplings, while others have mechanical couplings, and further implementations have both magnetic and mechanical couplings.

Quick-release end effectors and related systems and methods

A gas conditioning unit for a surgical gas delivery device is disclosed, which includes a filter housing having an insufflation gas flow path for delivering insufflation gas to a body cavity and for facilitating pressure measurements from the body cavity, a pressurized gas flow path for delivering pressurized gas from a pump in the surgical gas delivery device to an internal nozzle in the filter housing that accelerates the pressurized gas and thereby generates a continuous pressure barrier that inhibits egress of insufflation gas from the body cavity, a vacuum return flow path for returning depressurized gas spent by the internal nozzle back to the pump under vacuum, an air entrainment flow path for drawing air into the body cavity to maintain a given pressure therein, and a smoke evacuation flow path for conveying smoke from the body cavity.

Multipath filter assembly with integrated gaseous seal for multimodal surgical gas delivery system

An insufflation and smoke evacuation system for use during laparoscopic surgical procedures is disclosed that includes a pump for circulating pressurized gas within the system, a tri-lumen cannula communicating with an insufflation source by way of an insufflation supply line and with the supply side of the pump by way of a pressurized gas supply line, and a single lumen cannula communicating with a suction side of the pump by way of a vacuum line, wherein a communication line extends between the tri-lumen cannula and the vacuum line.

Systems and methods for conducting smoke evacuation during laparoscopic surgical procedures

A cannula assembly for use in robotic surgery is disclosed that includes a robotic cannula having a housing with an open end and a tubular portion extending distally from the housing, the tubular portion being dimensioned to accommodate passage of a surgical instrument having a 12 mm diameter, an adapter assembly configured for engagement within the open end of the cannula housing and including a tubular body with a passage supporting a primary seal dimensioned to accommodate passage of a surgical instrument having a 12 mm diameter, and an insert tube dimensioned to extend through the passage of the body portion of the adapter assembly and the tubular portion of the robotic cannula, the insert tube including a head portion with a passage supporting a secondary seal dimensioned to accommodate a surgical instrument having an 8 mm diameter.

Cannula assembly for robotically assisted pressure regulated laparoscopic surgical procedures

The subject invention is directed to a new and useful coupling system for connecting a tube set to a trocar. More particularly, the system includes a trocar connector having no more than two coaxial flow passages formed therein including an inner flow passage and an outer flow passage. The inner flow passage is defined by an inner annular wall and the outer flow passage is defined between the inner annular wall and an outer annular wall. A dual lumen tube set is included with a first tube having a first diameter and a second tube having a second diameter that is greater than the diameter of the first tube. The system further includes a coupling including a generally cylindrical body having a first end portion configured to mate with the two coaxial flow passages of the trocar connector and a second end portion configured for attachment to the two tubes of the dual lumen tube set.

A multi-lumen tube set is disclosed for use during a laparoscopic surgical procedure performed within a patient's abdominal cavity, which includes at least a first lumen configured to extend between a first surgical access port accessing the patient's abdominal cavity and an external vacuum source, and a branching conduit communicating with the first lumen and configured for connection to a second surgical access port accessing the patient's abdominal cavity to facilitate smoke evacuation from the patient's abdominal cavity during a laparoscopic surgical procedure.
