Magnetic coupling for surgical stapler
View Patent ↗A surgical tool may include a circular surgical stapler and an anvil initially disconnected and separate from the surgical stapler; where at least one of the circular surgical stapler and the anvil is magnetic.
1. A surgical tool, comprising:
a cylindrical surgical stapler having a first circular end and a second circular end;
an anvil initially disconnected and separate from said surgical stapler,
wherein at least one of said cylindrical surgical stapler and said anvil comprise a magnetic a material; and
a cutter extending from one of the surgical stapler or the anvil, wherein the cutter is operable to cut an opening through segments disposed between the surgical stapler and the anvil when one of the first circular end or the second circular end of the surgical stapler is proximate to the anvil, wherein the cylindrical surgical stapler and the anvil self-align with one another when disposed in different tubular structures via a magnetic field of the magnetic material prior to cutting the opening through the segments of the different tubular structures.
2. The surgical tool of claim 1 , wherein the anvil has a circular surface.
3. The surgical tool of claim 1 , further comprising:
a piercing fastener extending from one of the surgical stapler or the anvil.
4. The surgical tool of claim 1 , wherein the surgical stapler is operable to deploy a plurality of staples in a circular pattern.
5. The surgical tool of claim 1 , wherein the surgical stapler is actuated through a guidewire.
6. A surgical tool, comprising:
a surgical stapler having a first circular end and a second circular end, the surgical stapler is operable to deploy a plurality of staples in a circular pattern;
an anvil initially disconnected and separate from said surgical stapler, wherein at least one of the circular surgical stapler and the anvil comprise a magnetic a material; and
a cutter extending from one of the surgical stapler or the anvil, wherein the cutter is operable to cut an opening through segments disposed between the surgical stapler and the anvil when one of the first circular end or the second circular end of the surgical stapler is proximate to a surface of the anvil, wherein the cylindrical surgical stapler and the anvil self-align with one another when disposed in different tubular structures via a magnetic field of the magnetic material prior to cutting the opening through the segments of the different tubular structures.
7. The surgical tool of claim 6 , wherein the surface of the anvil is circular.
8. The surgical tool of claim 6 , further comprising:
a piercing fastener extending from one of the surgical stapler or the anvil.
9. The surgical tool of claim 6 , wherein the surgical stapler is operable to deploy a plurality of staples in a circular pattern.
10. The surgical tool of claim 6 , wherein the surgical stapler is actuated through a guidewire.
