Robotically-driven surgical instrument with E-beam driver

摘要

A surgical severing and stapling instrument, suitable for laparoscopic and endoscopic clinical procedures, clamps tissue within an end effector of an elongate channel pivotally opposed by an anvil. Various embodiments are configured to be operably attached to a robotic system to receive actuation/control motions therefrom.

主权项

1. A surgical instrument comprising:
an implement portion responsive to firing motions from a robotic system communicating therewith and being diametrically dimensioned for endo-surgical use, the implement portion comprising: an elongate channel coupled to an elongated shaft operably interfacing with said robotic system and including a channel slot; an anvil pivotally coupled to the elongate channel, responsive to closing motions generated by said robotic system and applied thereto by the elongated shaft, and including an anvil channel; and a firing device including a distally presented cutting edge longitudinally received between the elongate channel and the anvil, the firing device configured to affirmatively space the anvil from the elongate channel during longitudinal travel between the anvil and elongate channel, by including:
an upper member having a first upper surface and a first lower surface that longitudinally slidingly engage the anvil;a lower pin including a second upper surface abutting the elongate channel; anda middle pin including a second lower surface that slidingly engages the elongate channel.
