Publication number: 20190167302Abstract: In the Abstract, please include the following paragraph, following the claim set: A surgical access device includes a proximal housing having proximal and distal end portions, the distal end portion of the housing being configured and adapted to engage a proximal portion of a flexible wound retractor. The proximal housing can be provided with a plenum chamber being defined therein, the plenum chamber being in fluid communication with at least one nozzle. The nozzle is preferably configured to direct pressurized fluid in an axial direction from the plenum chamber into a fluid in an axial direction from the plenum chamber into a central bore of the surgical access device to provide a constant gaseous seal around a surgical instrument inserted therethrough, while inhibiting a loss of pressurized fluid from the body cavity therethrough. The plenum chamber can be adapted and configured to receive pressurized fluid and conduct the pressurized fluid to the at least one nozzle.Type: ApplicationFiled: November 18, 2016Publication date: June 6, 2019Applicant: Surgiquest, Inc.Inventors: Ralph Stearns, James R.

Patent number: 9414818Abstract: 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.Type: GrantFiled: January 14, 2015Date of Patent: August 16, 2016Assignee: SurgiQuest, Inc.Inventors: Kurt Azarbarzin, Dominick Mastri, Ralph Stearns
