Embodiment Construction

[0095] Turning to the drawings, in which like numerals represent like elements throughout, FIG. 1 illustrates a surgical stapling and cutting instrument 10 that is capable of practicing some of the unique advantages of the present invention. The surgical stapling and cutting instrument 10 includes an end effector 12 that is manually actuated by operation of a control member on a handle assembly 200 coupled thereto. A variety of different end effector configurations are known. One type of end effector 12 that may be used in various embodiments of the invention is shown in FIGS. 1 , 2 and 5-9. As shown in some of those figures, end effector 12 employs an E-beam firing mechanism ("firing bar") 30 that advantageously controls the spacing of end effector 12 . Various aspects of the E-beam firing mechanism are described in US Pat. No. 6,978,921 to Shelton IV et al., entitled Surgical Stapling Instrument Incorporating an E-Beam Firing Mechanism, the relevant parts of which are incor...

Abstract

A surgical cutting and fastening instrument that includes an elongate channel that is attached to a handle assembly by an elongate shaft assembly. The elongate channel is configured to receive a cartridge and has a pivotally translatable anvil attached thereto and a knife bar supported therein. The anvil may be selectively opened and closed by manipulating a closure trigger supported by the handle assembly. The knife bar may be distally advanced through the elongate channel by actuating a firing trigger that cooperates with a reversible rotary drive supported by the handle assembly. The knife bar may also be retracted to its starting position by actuating the firing trigger after the reversible rotary drive has been shifted to a retraction orientation.

Description

technical field [0001] The present invention relates generally to surgical instruments, and in particular to surgical cutting and fastening instruments. The invention may have application in conventional endoscopic and open surgical instrumentation as well as in robotic assisted surgery. Background technique [0002] Surgical staplers have been used in the prior art to simultaneously make a longitudinal incision in tissue and apply staple lines on opposite sides of the incision. The instrument generally includes a pair of cooperating jaw members capable of passing through the cannula channel if the instrument is to be used in endoscopic or laparoscopic applications. One of the jaw members receives a staple cartridge having at least two laterally spaced rows of staples. The other jaw member defines an anvil having staple-forming slots aligned with the rows of staples in the staple cartridge. The instrument includes a plurality of reciprocating wedges that, when driven dist...
