Surgical fastener for applying a large staple through a small delivery port
First Claim
1. A fastener applying device comprising:
- a. a handle having a trigger pivotably attached thereto and movable within a trigger plane, said trigger having a bottom portion extending from said handle and a top portion disposed within a housing of said handle;
b. a staple housing having a proximal end attached to a handle, a distal end extending therefrom and a longitudinal axis therebetween, said handle housing having a firing bar disposed within, said trigger is coupled to said firing bar; and
c. a link member having a first end pivotably attached to said top portion of trigger, said link member having a second end comprising a slidable pin, said pin engaging a three dimensional cam path disposed within said handle housing, wherein said three dimensional cam path follows a circuitous path loop, wherein said link member follows distal and proximal movement of said top portion of said trigger, and said pin slides perpendicular to said trigger plane to follow said three dimensional cam path.

Abstract
A surgical fastener applying device having a handle with a trigger pivotably attached thereto and movable within a trigger plane. The trigger has a bottom portion extending from the handle and a top portion disposed within a housing of the handle. The device has a staple housing with a proximal end attached to the handle, a distal end extending therefrom and a longitudinal axis therebetween. The housing has a firing bar disposed within, and the trigger is coupled to the firing bar. The device has a link member with a first end pivotably attached to the top portion of trigger, the link member has a second end comprising a slidable pin. The pin engages a three dimensional cam path disposed within the housing. The link member follows distal and proximal movement of the top portion of the trigger, and the pin slides perpendicular to the trigger plane to follow the three dimensional cam path.
