  • Publication number: 20240285331
    Abstract: Provided is an endoscopic vessel harvesting system comprising a direct current (DC) power control system connected to a therapeutic tool comprising a heating element. The DC power control system may include an input connection to receive power from a power supply. A first power control circuit may supply constant output power during a first time interval to heat the heating element to a target temperature. A second power control circuit may supply pulsed output power during a second time interval to maintain a temperature of the heating element within a target temperature range. An output connection may receive the output power and may supply controlled power to the heating element by supplying the constant output power during the first time interval, the pulsed output power during the second time interval, followed by a third time interval during which no power is supplied. Methods and systems are also disclosed.

  • Publication number: 20240173066
    Abstract: A surgical instrument for harvesting an organ includes a surgical tool and a handle. The handle includes an actuator rotatable about an actuator pivot pin and a cam connected to the actuator and rotatable in tandem with the actuator. The surgical instrument further includes an actuator rod having a distal end connected to the surgical tool and a proximal end connected to the cam. The cam defines a slot which captures a portion of the actuator rod. The portion of the actuator rod captured in the slot is slidable within the slot as the cam rotates. Sliding of the portion of the actuator rod in the slot actuates the surgical tool.

  • Publication number: 20240099741
    Abstract: A vessel harvesting device includes a handle and a cannula assembly extending distally from the handle. The cannula assembly includes an outer tube having a flange, and at least one insert extending within the outer tube. The at least one insert defines a tool path configured to receive a surgical tool therethrough, a scope path configured to receive a surgical scope therethrough, and an insufflation channel. The device further includes a cannula gasket disposed within the flange of the outer tube and defining a plurality of apertures each in alignment with one of the tool path, the scope path, and the insufflation channel. The device further includes an insufflation tube extending from the handle through cannula gasket and the insufflation channel.

  • Publication number: 20010051118
    Abstract: Improvements to chemical reaction systems provide for the production of commercial quantities of chemical products, such as chemical powders. The improved chemical reaction systems can accommodate a large reactant flux for the production of significant amounts of product. Preferred reaction systems are based on laser pyrolysis. Features of the system provide for the production of highly uniform product particles.

  • Patent number: 6270732
    Abstract: A particle collection apparatus has a chamber, one or more filters and a back pressure system. The filters are located in the flow path through the system to collect the particles from an input gas stream. The back pressure system applies a pulse of gas against the flow through the system to dislodge particles collected on the filters. The dislodged particles fall to a particle drain where they are removed from the system. The particle collection apparatus can be connected to a particle synthesis apparatus. The particle collection apparatus and the particle synthesis apparatus can operated at reduced pressures.
