Publication number: 20200015820Abstract: 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: ApplicationFiled: September 27, 2019Publication date: January 16, 2020Inventors: Elizabeth Contini, Kelly Valentine, Thomas Wingardner, David McCuen, Matthew Chowaniec, John Beardsley, Russell Pribanic, Xingrui Chen
