Patent number: 10413295Abstract: An engaging element for engaging tissue that includes a first member and a second member. The first member includes at least one tissue engaging portion at a first free end. The first tissue engaging member is movable between an open position and a closed position and has a second free end. The first tissue engaging member is restrained in movement at an intermediate position between the first free end and the second free end. A lock portion is operatively associated with the first member with the lock portion maintaining a spacing between the first member and the second member and inhibiting movement of the first member to the open position. The lock portion is operatively associated with a portion of the first tissue engaging member proximal the intermediate position.Type: GrantFiled: March 14, 2016Date of Patent: September 17, 2019Assignee: Abbott LaboratoriesInventor: Arkady Kokish

Patent number: 10098705Abstract: A surgical system having a patient side cart having at least one telesurgically operated instrument, the at least one telesurgically operated instrument comprising a surgical end effector having a plurality of effector components. A transmission is coupled to a motor. The drive train includes at least a first effector drive train and a second effector drivetrain. A controller comprises at least one processor for controlling the transmission. The controller is performs a method by locking an output gear of the second effector drivetrain rotating a camshaft to shift coupling of the motor from the first effector drivetrain to the second effector drivetrain; determining that the output gear is aligned by driving the locked output gear using a first torque; determining that the output gear is properly braked by driving the locked output gear using a second torque; disengaging the lock from the output gear; and driving the second effector drivetrain using the motor.Type: GrantFiled: March 31, 2015Date of Patent: October 16, 2018Assignee: Intuitive Surgical Operations, Inc.Inventors: Gabriel F. Brisson, Niels Smaby, Melody Wu

Patent number: 9693798Abstract: A tool introducer is configured for introduction in an elongated body including a straight tube, wherein the tube encloses a tube lumen opened at its distal end with a tube opening. The tool introducer includes locking means to selectively lock or unlock an interchangeable surgical tool to the tube from displacing axially and/or rotationally in the tube lumen, the locking means being configured such that, at the locking, a tool connector of the tool projects towards the tube opening and is distanced therefrom by at least 3 cm. A method includes positioning the surgical tool introducer such that a distal portion thereof projects in a body cavity, manipulating and/or extending the tool introducer to reach and engage an elongated shaft introduced percutaneously into the body cavity; and inserting the elongated shaft into the tube lumen via the tube opening and connecting the tool to the elongated shaft.Type: GrantFiled: February 24, 2014Date of Patent: July 4, 2017Assignee: EON SURGICAL LTD.Inventors: Danny Farin, Yehuda Bachar

Patent number: 9186165Abstract: A surgical instrument includes a pair of jaw members moveable between a spaced-apart and an approximated position. A drive bar is translatable between a distal and a proximal position for moving the jaw members between the spaced-apart and approximated positions. A lever is moveable between an initial position and an actuated position for translating the drive bar between the distal and proximal positions. A sleeve disposed about the drive bar includes an annular track having a substantially radial segment(s) and a substantially longitudinal segment(s). A collar interdisposed between the sleeve and the drive bar includes a stop member(s) extending radially outwardly therefrom. The stop member(s) is engaged within the track and is translatable from a first position, wherein the stop member is positioned within the longitudinal segment, to a second position, wherein the stop member is engaged within the radial segment, to lock the lever in the actuated position.Type: GrantFiled: December 10, 2013Date of Patent: November 17, 2015Assignee: Covidien LPInventors: John R.
