A linear surgical stapler having clamping and firing triggers pivotally mounted to the frame of the instrument for pivotal rotation toward a hand grip is disclosed. The clamping trigger is positioned between the firing trigger and the hand grip. Each of the triggers are pivotally mounted to pivot pins spaced from each other within the body portion of the frame. Pivotal rotation of the first trigger is independent of pivotal rotation of the second trigger. When the clamping trigger is pivotally rotated toward the hand grip, the clamping and firing transmission assemblies move distally in tandem. Before the first trigger is pivoted, the firing transmission assembly blocks pivotal rotation of the second trigger. When the first trigger is pivoted, the initial distal movement of the firing transmission assembly enables the firing trigger to be in a position to pivotally rotate, and therefore cause the firing of staples. Additionally, a feature enabling the retention of the clamping trigger in intermediate and fully clamped positions is disclosed, where upon release of the retention feature, the clamping trigger can return to its original position by overriding the intermediate position. Finally, although the invention is described with particular reference to a linear stapler containing clamping and firing triggers, it has broader applicability to any surgical instrument which has first and second triggers pivotally actuated to transmit work to an end effector for performing first and second surgical functions during a desired surgical procedure.
A surgical instrument comprising: a) a frame at a first end of said instrument for gripping and manipulating said instrument, said frame having a body portion and a hand grip descending from said body portion thereof; b) an end effector at an opposite end of said instrument for performing a surgical
A surgical instrument comprising: a) a frame at a first end of said instrument for gripping and manipulating said instrument, said frame having a body portion and a hand grip descending from said body portion thereof; b) an end effector at an opposite end of said instrument for performing a surgical procedure; c) a first trigger pivotally mounted to a first pivot pin within said body portion of said frame for pivotal rotation in a counterclockwise direction from an unactuated first trigger position spaced from said hand grip to a fully actuated first trigger position adjacent said hand grip; d) a first transmission assembly having proximal and distal ends, the proximal end of said first transmission assembly coupled to said first trigger and the distal end of said first transmission member coupled to said end effector, wherein: (i) when said first trigger is pivotally rotated in the counterclockwise direction from said unactuated first trigger position toward said hand grip, said first transmission assembly moves distally so as to cause said end effector to perform a first surgical function in the surgical procedure; e) a second trigger pivotally mounted to a second pivot pin within said body portion of said frame for pivotal rotation in a counterclockwise direction from an unactuated second trigger position spaced from said first trigger to a fully actuated second trigger position adjacent said first trigger, wherein said second pivot pin is spaced from said first pivot pin, said pivotal rotation of said second trigger is independent of said pivotal rotation of said first trigger, and said first trigger is positioned between said second trigger and said hand grip; and f) a second transmission assembly having proximal and distal ends, the proximal end of said second transmission assembly being engagable with said second trigger and the distal end of the said second transmission assembly being engagable with said end effector, wherein: (i) when said first trigger is positioned in said unactuated first trigger position, the proximal end of said second transmission assembly blocks the pivotal rotation of said second trigger in a counterclockwise direction; (ii) when said first trigger is pivotally rotated in the counterclockwise direction from said unactuated first trigger position toward said hand grip, said second transmission assembly moves distally concurrently with said first transmission assembly so as to prevent blocking of said pivotal rotation of said second trigger; and (iii) when said first trigger is positioned in said fully actuated first trigger position and said second trigger is pivotally rotated in a counterclockwise direction toward said first trigger, said second transmission assembly continues to move distally so as to cause said end effector to perform a second surgical function in the surgical procedure.
