Patent number: 11918216Abstract: An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.Type: GrantFiled: March 21, 2022Date of Patent: March 5, 2024Assignee: COVIDIEN LPInventors: Elizabeth Contini, Kelly Valentine, Thomas Wingardner, David McCuen, Matthew Chowaniec, John Beardsley, Russell Pribanic, Xingrui Chen, Christopher Switalski

Patent number: 11382623Abstract: A handheld electromechanical surgical device includes a non-sterile power-pack having a drive component(s) including a rotatable drive shaft extending therefrom, a main processor configured to control each drive component, a battery configured to power each drive component, an electrical receptacle, and a control interface(s) configured to control a functionality of the drive component. A sterile outer shell housing is configured to removably encase the power-pack to define a sterile barrier thus enabling use in a surgical environment without breaking sterility. The outer shell housing includes a coupler configured to transmit a rotation from the rotatable drive shaft through the outer shell housing, a control button(s) operatively positioned such that actuation of the control button actuates the control interface, and a pass-through connector configured to transmit electrical communications from the electrical receptacle through the outer shell housing.Type: GrantFiled: September 27, 2019Date of Patent: July 12, 2022Assignee: Covidien LPInventors: Elizabeth Contini, Kelly Valentine, Thomas Wingardner, David McCuen, Matthew Chowaniec, John Beardsley, Russell Pribanic, Xingrui Chen

Patent number: 10925600Abstract: A surgical instrument and method of controlling the surgical instrument are disclosed. The surgical instrument includes a housing and an elongated shaft that extends distally from the housing and defines a first longitudinal axis. The surgical instrument also includes a firing rod disposed in the elongated shaft and a drive mechanism disposed at least partially within the housing. The drive mechanism mechanically cooperates with the firing rod to move the firing rod. A motion sensor senses a change in the electric field (e.g., capacitance, impedance, or admittance) between the firing rod and the elongated shaft. The measurement unit determines a parameter of the motion of the firing rod, such as the position, speed, and direction of the firing rod, based on the sensed change in the electric field. A controller uses the measured parameter of the motion of the firing rod to control the drive mechanism.Type: GrantFiled: October 12, 2018Date of Patent: February 23, 2021Assignee: COVIDIEN LPInventor: David McCuen
