SURGICAL STAPLING INSTRUMENT WITH IMPROVED FIRING TRIGGER ARRANGEMENT
First Claim
1. A surgical stapling instrument, comprising:
- a first side;
a second side;
a longitudinal axis;
a first housing member, comprising;
a staple cartridge attachment portion configured to operably support a staple cartridge; and
a first lock rail extending along said longitudinal axis;
a second housing member, comprising;
a jaw member configured to operably support an anvil configured to deform staples deployed from the staple cartridge; and
a second lock rail extending along said longitudinal axis;
a pusher bar configured to move a staple driver relative to said staple cartridge attachment portion and said jaw member; and
an actuator configured to receive a force thereto, wherein said actuator is configured to be moved between a first position and a second position, wherein said actuator is configured to be moved along said first side when said actuator is in said first position, wherein said actuator is configured to be moved along said second side when said actuator is in said second position, and wherein said actuator further comprises at least one lock rail receiver configured to receive said first lock rail and said second lock rail.

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.
