Surgical stapling instrument with improved firing trigger arrangement
First Claim
1. A surgical stapling instrument, comprising:
- a housing having a first side and a second side;
a first jaw member configured to operably support a staple cartridge having at least two rows of staples stored therein, wherein at least one of said first jaw member and the staple cartridge is configured to slidably support a staple driver configured to deploy the staples from the staple cartridge;
a second jaw member configured to operably support an anvil configured to deform the staples when the staples are deployed from the staple cartridge;
a pusher bar configured to move the staple driver relative to said first jaw member and said second jaw member; and
an actuator knob configured to receive a force thereto, wherein said actuator knob is rotatably mounted to said pusher bar, wherein said actuator knob is configured to be rotated between a first position and a second position, wherein said actuator knob is configured to be moved along said first side and not along said second side when said actuator knob is in said first position, and wherein said actuator knob is configured to be moved along said second side and not along said first side when said actuator knob is in said second position.

Abstract
A surgical stapling instrument including an actuator knob which can be moved from one side of the stapling instrument to another side in order to reposition the actuator knob without having to reposition the stapling instrument within a surgical site. A stapling instrument can include a pusher bar, a housing having a first side and a second side, and an actuator knob rotatably mounted to the pusher bar wherein the actuator knob can be configured to be rotated between a first position in which the actuator knob can be moved along the first side of the housing and a second position where the actuator knob can be moved along a second side of the housing. Alternatively, a surgical stapling instrument can comprise one or more actuator knobs which can be operably engaged and disengaged with a pusher bar in order to selectively utilize the actuator knobs.

10. A surgical stapling instrument, comprising:
-
a housing having a first slot and a second slot; a first jaw member configured to operably support a staple cartridge having at least two rows of staples stored therein, wherein at least one of said first jaw member and the staple cartridge is configured to slidably support a staple driver configured to deploy the staples from the staple cartridge, and wherein said first jaw member includes a distal end; a second jaw member configured to operably support an anvil configured to deform the staples when the staples are deployed from the staple cartridge, wherein said second jaw member includes a distal end; a pusher bar configured to move the staple driver relative to said first jaw member and said second jaw member; and an actuator knob extending from said pusher bar, wherein said actuator knob is configured to be selectively positioned within one of said first slot and said second slot and moved toward said distal ends of said first and second jaw members such that said actuator knob is not concurrently positioned within said first slot and said second slot. - View Dependent Claims (11, 12, 13, 14)

15. A surgical stapling instrument, comprising:
-
a housing; a first jaw member configured to operably support a staple cartridge having at least two rows of staples stored therein, wherein at least one of said first jaw member and the staple cartridge is configured to slidably support a staple driver configured to deploy the staples from the staple cartridge; a second jaw member configured to operably support an anvil configured to deform the staples when the staples are deployed from the staple cartridge; a pusher bar configured to move the staple driver relative to said first jaw member and said second jaw member; and an actuator knob selectively engageable with said pusher bar, wherein said actuator knob is rotatable between a first position and a second position, wherein said actuator knob is operably disengaged from said pusher bar when it is in said first position such that said pusher bar is structured to move relative to said actuator knob, and wherein said actuator knob is operably engaged with said pusher bar when it is in said second position such that said pusher bar is structured to move with said actuator knob. - View Dependent Claims (16, 17, 18, 19, 20)
