Publication number: 20200289119Abstract: A surgical apparatus has a clamp and a stapling mechanism. The clamp has a first jaw and a second jaw to clamp on a body tissue at a desired location for a stapling operation. The stapling mechanism is controlled by a trigger handle or a switch assembly. The surgical apparatus has a controller for providing a delay between clamping and actuating of the firing mechanism of the stapling mechanism. The delay provides for a desired amount of time for tissue compression producing a more uniform staple formation. The surgical apparatus also has an indicator. The indicator provides feedback about the status of the stapling mechanism and also displays a time of tissue compression by the clamp.Type: ApplicationFiled: June 3, 2020Publication date: September 17, 2020Inventors: Frank J. Viola, Gregg Krehel, Guido Pedros, Michael A. Soltz, Robert J. DeSantis, Henry E. Holsten, Russell Heinrich, Michael Ingmanson, Philip Irka, David M. McCuen, Gene A. Stellon

Patent number: 9693771Abstract: A staple is provided having a backspan and a first and second legs extending distally from the backspan. Each of the first and second legs includes a bend dividing each leg into a traversing leg portion and a substantially linear clenching leg portion. A staple plate is positionable over the first and second legs between the backspan and the first and second clenching leg portions. An anvil assembly has first and second movable members which move toward to one another to engage outer surfaces of the first and second clenching leg portions. There is further disclosed a method of forming the staple through tissue.Type: GrantFiled: October 9, 2013Date of Patent: July 4, 2017Assignee: Covidien LPInventors: Russell Heinrich, Robert J. DeSantis, Richard D. Gresham, Kenneth Blier

Patent number: 9636128Abstract: A safety handle assembly for use with a surgical instrument having an operative distal end portion is disclosed. The handle assembly includes a handle housing and a drive element movably mounted within the handle housing and connected to an associated operative distal end portion. A drive assembly is positioned within the handle housing and is engageable with the drive element to move the drive element within the handle housing. An actuator is movably mounted on the handle housing and an adjustable force-limiting mechanism is interposed between the drive assembly and the actuator. A force-limiting mechanism releasably connects the actuator to the drive assembly. The force-limiting mechanism is adjustable to preset the force at which the actuator separates or breaks away from the drive assembly.Type: GrantFiled: February 5, 2014Date of Patent: May 2, 2017Assignee: Covidien LPInventors: Michael Zemlok, Paul A. Scirica, Robert J. DeSantis

Patent number: 9326761Abstract: An access device includes a body, a first tube, a second tube, and a mechanism. The first and second tubes extend through the body. The mechanism operably couples the first and second tubes such that at least one tube is pivotable about an axis with respect to the other tube. The body may form a substantially fluid-tight seal at the incision. In another embodiment, the access device further includes a third tube extending through the body and the mechanism operably couples the tubes together such that at least two tubes are pivotable about the axis with respect to the remaining tube.Type: GrantFiled: December 10, 2013Date of Patent: May 3, 2016Assignee: Covidien LPInventors: Thomas Wingardner, III, Gene A. Stellon, Robert J. DeSantis

Patent number: 8784305Abstract: A method of retracting and/or manipulating tissue is provided. The method includes providing access to a body cavity, providing a retractor including a elongated body portion, a needle formed on a proximal end of the elongated body portion and an anchor means formed on a distal end of the elongated body portion, directing the needle of the retractor through a section of tissue to be retracted, drawing the retractor though the tissue until the anchor means engages the tissue, and pulling the body portion of the retractor to manipulate the tissue.Type: GrantFiled: October 1, 2009Date of Patent: July 22, 2014Assignee: Covidien LPInventors: Robert J.
