Abstract
Official abstract text for this publication.
A surgical instrument system that includes a housing and a rotatable drive shaft, a motor operably coupled to the drive shaft, and a plurality of replaceable end effectors that can be connected to the housing. Each replaceable end effector includes a drive screw that is turned a fixed number of revolutions by the motor-driven rotatable drive shaft when the end effector is connected to the housing. Each end effector further comprises a firing member operably coupled with the drive screw of the end effector. The drive screw is configured to displace the firing member over a firing length as a result of the fixed number of revolutions. In certain embodiments, each replaceable end effector can include a drive screw with a thread pitch set to the firing length divided by the fixed number of revolutions.
First claim
Opening claim text (preview).
What is claimed is: 1. A surgical instrument system, comprising: a housing including a motor-driven drive shaft, wherein said motor-driven drive shaft is configured to turn a set number of revolutions during a firing actuation; a first end effector assembly configured to be coupled to and decoupled from said housing, wherein said first end effector assembly defines a first firing path having a first firing length, said first end effector assembly comprising: a first firing memb…
