  • Publication number: 20180036024
    Abstract: A surgical device includes a housing, at least one electrical wire, a shaft, and an end effector assembly. The housing defines an interior cavity and first and second housing portions. The first and second housing portions are configured to engage one another to enclose the interior cavity. A channel is defined within an outer perimeter of the first and/or second housing portion such that engagement of the first and second housing portions encloses the channel separate from the interior cavity. The electrical wire(s) is housed within the channel and adapted to connect to a source of energy. The shaft is coupled to the housing and extends distally therefrom. The end effector assembly is disposed at a distal end of the shaft, wherein the end effector assembly is electrically coupled to the at least one electrical wire for supplying energy to the end effector assembly.
