Driverless surgical stapler
View Patent ↗An exemplary driverless surgical stapler may include a staple holder; staples positioned within that staple holder; and at least one wedge, where each wedge is slidable to directly contact at least one staple, where that contact causes deployment of each contacted staple. An exemplary surgical method may include providing a driverless surgical stapler that has a staple holder, staples positioned within the staple holder, and at least one wedge; and sliding at least one wedge relative to the staples to directly contact at least one staple.
1. A driverless surgical stapler, comprising:
a staple holder;
a plurality of staples positioned within said staple holder;
at least one wedge, each wedge slidable relative to the staple holder to directly contact at least one said staple, wherein said contact causes deployment of said at least one staple; and
a feeder belt to which at least one of said staples is frangibly affixed in a manner such that contact between at least one said wedge and a corresponding said staple causes said staple to first deform while affixed to said feeder belt and then to break away from said feeder belt.
2. The surgical stapler of claim 1 , wherein at least one said wedge includes a first surface and a second surface distinct from said first surface, wherein said first surface contacts at least one said staple to deform said staple and said second surface contacts at least one said staple to break said staple from said feeder belt.
3. The surgical stapler of claim 2 , wherein said first surface is curved upward and distally.
4. The surgical stapler of claim 1 , wherein said feeder belt is advanceable after said deployment.
5. The surgical stapler of claim 1 , wherein said feeder belt is movable.
6. The surgical stapler of claim 1 , wherein at least one said wedge includes a surface that extends upward in the proximal direction, further comprising a peak at the proximal end of said surface.
7. The surgical stapler of claim 6 , wherein said surface is substantially planar.
8. The surgical stapler of claim 6 , wherein said surface is at least partially curved.
9. The surgical stapler of claim 1 , wherein motion of said wedge directly transmits force to at least one said staple to cause said deployment.
10. The surgical stapler of claim 1 , wherein at least one said wedge is initially positioned distal to at least one staple; wherein at least one said wedge is slidable in the proximal direction to deploy at least one said staple.
11. The surgical stapler of claim 1 , wherein said staple holder is cartridgeless.
