An anti-reverse apparatus includes a latch capable of stopping an end sealing piece from moving reversely, and a loose switch capable of relieving a stop action by the latch on the reverse movement of the end sealing piece. Limitation of the latch on the reverse movement of the end sealing piece can be relieved by pressing the loose switch down. When the end sealing piece is detachably mounted at a near end of a sleeve in a rotating manner, the latch can stop reverse movement causing loosening of the end sealing piece and prevent air leakage or the end sealing piece from loosening from the near end of the sleeve. When the loose switch is pressed down, limitation of the latch on the reverse movement of the end sealing piece can be relieved, and the end sealing piece can be detached from the near end of the sleeve.

An adapter used with a surgical access assembly is disclosed. The adapter includes an adapter body and a positioning member. The adapter body is defined by a distal end and a proximal end opposite the distal end. The positioning member extends from the distal end of the adapter body. A channel extends through the adapter body, extending from the proximal end and toward the distal end.

A surgical gas delivery system is disclosed for gas sealed insufflation and recirculation during an endoscopic or laparoscopic surgical procedure, which includes a gaseous sealing manifold for communicating with a gas sealed access port, a compressor for recirculating gas through the gaseous sealing manifold, and a source of UVC irradiation for sterilizing at least the gas recirculating through the gaseous sealing manifold.

A surgical gas delivery system is disclosed for gas sealed insufflation and recirculation, which includes a gaseous sealing manifold for communicating with a gas sealed access port, an insufflation manifold for communicating with the gas sealed access port and with a valve sealed access port, a compressor for recirculating gas through the gas sealed access port by way of the gaseous sealing manifold, a first outlet line valve associated with the insufflation manifold for controlling a flow of insufflation gas to the gas sealed access port, a second outlet line valve associated with the insufflation manifold for controlling a flow of insufflation gas to the valve sealed access port, and a proportional valve associated the insufflation manifold and located upstream from the first and second outlet line valves for dynamically controlling the flow of insufflation gas to the first and second outlet line valves.

A manifold assembly for a surgical gas delivery system is disclosed, which includes a manifold body including an inlet port for receiving gas from an outlet side of a compressor and an outlet port for recirculating gas to an inlet side of the compressor, a bypass valve communicating with the inlet port and the outlet port of the manifold body, an air ventilation valve for dynamically controlling the ingress of air from atmosphere, a smoke evacuation valve for dynamically controlling the egress of gas from the manifold assembly when the gas delivery system is operating in a smoke evacuation mode, and a gas fill for dynamically controlling the receipt of gas from a source of surgical gas.

An ophthalmic surgical system includes a cannula having a receptacle. The receptacle includes a valve and a first lip extending inwardly and defining at least a portion of a chamber in the receptacle. The ophthalmic surgical system also includes a surgical instrument having a second lip that is sized and shaped to engage with the first lip of the cannula to couple the surgical instrument to the cannula.

Proposed is a trocar system for a laparoscopic surgery, the trocar system preventing improper suturing caused by shaking of the focus of a suturing needle during suturing of the peritoneal hole of the peritoneum after completion of a laparoscopic surgery, and including a suturing needle guide member having first and second suturing needle guide holes, a trocar unit detachably coupled to the suturing needle guide member and having third, fourth, fifth, and sixth suturing needle guide holes, a trocar to which the suturing needle guide member is detachably coupled and which is provided with seventh and eighth suturing needle guide holes, and a suturing needle provided with suturing thread guided through the first, third, fifth, and seventh suturing needle guide holes and second, fourth, sixth, and eighth suturing needle guide holes.

A vessel harvesting apparatus for removing a blood vessel from a patient includes collection and conditioning (i.e., treatment) of expelled insufflation gas prior to releasing the gas into the air of the operating room. An endoscopic instrument has a distal end with a vessel harvesting tip and has a proximal end with a handle. An insufflation channel is configured to convey an insufflation gas subcutaneously into a dissected space within the patient. A removal channel is configured to evacuate fluidic contents from the dissected space, wherein the fluidic contents include insufflation gas and biological impurities. A processor/separator is coupled to the removal channel to process the fluidic contents to retain at least some of the biological impurities and to exhaust the insufflation gas.

A surgical introducer system having an outer introducer sidewall extending along a longitudinal axis from a proximal introducer end to a distal introducer end, an inner introducer sidewall extending within the outer introducer sidewall along the longitudinal axis and forming an introducer passage extending in a distal direction from a proximal passage opening at the proximal introducer end to an introducer passage end wall located proximal to the distal introducer end, and an end wall passage extending from the introducer passage end wall towards the distal introducer end. The introducer end wall passage joins the introducer end wall at one or more end wall edges defining an axial stop ring configured to contact the distal tip of a navigation probe between the probe shaft and a terminal end of the distal probe tip at a line of contact to thereby prevent movement of the navigation probe in the distal direction.

Systems and methods for reducing insufflation loss due to gas leakage during a laparoscopic surgical procedure are provided. The surgical procedure includes the use of a surgical instrument having an end effector and a trocar through which the surgical instrument is inserted for access to the abdominal cavity of a patient receiving laparoscopic surgery. The trocar includes a lip, a lip seal disposed within the lip, and a cannula located beneath the lip. The systems and methods reduce or prevent a loss of insufflation when using conventional systems and methods to insert the surgical instrument through a conventional trocar.
