Abstract

Systems and methods discussed herein relate to surgical systems including tissue resecting devices where the handset has a disposable portion detachably coupled to a reusable portion. The reusable portion may be a housing where a motor and electronics are stored that may be used to drive a shaft inserted into the disposable portion. The shaft may be coupled to a fluid pathway through the disposable portion that is fluidly isolated from the reusable section. After use, the disposable section is detached from the reusable section and disposed, and the reusable section may be cleaned and sterilized, or may be cleaned only.
