Embodiment Construction

[0034] Referring to the drawings, in which like reference numerals denote like components, Figure 1-3 There is shown a surgical device, more particularly a surgical stapling and severing device 10 in the described embodiment, which is capable of realizing the unique advantages of the present invention. especially in figure 1In the unattached state shown, the surgical stapling and severing device 10 is sized for insertion through the trocar cannula channel to a surgical site on a patient to effectuate a surgical procedure. Such as figure 2 As shown, once the articulation mechanism 11 and the distally attached end effector 12 are inserted through the cannula channel, the articulation mechanism 11 can be indirectly connected by the articulation controller 13 . Thus, the end effector 12 can reach behind the organ, or approach the organ from a desired angle or for other reasons. For example, the trigger mechanism, advantageously in order to cut off the E-beam trigger lever 14 ...

Abstract

A surgical stapling and severing instrument particularly suited to endoscopic articulates an end effector by having a general articulation mechanism that converts rotational motion from a handle portion. A firing bar longitudinally translates between the handle portion and the end effector. The firing bar head is thickened in order to present an undistorted cutting edge and engagement features to the opposing jaws of the end effector. The firing bar also advantageously includes a thinned or tapered proximal portion in the form of a strip or band that negotiates the articulation mechanism flexibility. To prevent buckling of the firing bar strip during firing, a pair of support plates adjustably flank the firing bar strip through the articulation mechanism. To advantageously prevent pinching, retaining bars are positioned between the support plates above the firing bar to maintain spacing therethrough.
