Staple position sensor system
A surgical stapling instrument includes a handle assembly, an elongate shaft extending distally from the handle assembly, and a tool assembly coupled to a distal end of the elongate shaft. The tool assembly includes a cartridge assembly including a plurality of surgical staples each including a code embedded portion and a first sensor for detecting the position of the surgical staples prior to and during a formation of the staples. The tool assembly further includes an anvil assembly including a second sensor that detects the position of the surgical staples after the formation of the surgical staples.
1. A surgical stapling instrument comprising:
a surgical staple including a backspan and a pair of legs extending from the backspan, at least one leg of the pair of legs including a code embedded portion; and
a tool assembly including a first jaw member and a second jaw member selectively positionable relative to the first jaw member, the first jaw member including a first sensor configured to detect a position of the code embedded portion of the surgical staple.
2. The surgical stapling instrument according to claim 1 , wherein the first sensor of the first jaw member is configured to detect the position of the code embedded portion of the surgical staple in an unformed state.
3. The surgical stapling instrument according to claim 1 , wherein the first jaw member defines a retention channel configured to receive the surgical staple therein, the first sensor positioned adjacent the retention channel.
4. The surgical stapling instrument according to claim 3 , wherein the first sensor and the code embedded portion of the surgical staple are aligned when the surgical staple is properly loaded in the retention channel prior to formation of the surgical staple.
5. The surgical stapling instrument according to claim 3 , wherein the first sensor is exposed to the retention channel.
6. The surgical stapling instrument according to claim 1 , wherein the second jaw member includes an anvil assembly.
7. The surgical stapling instrument according to claim 1 , wherein the second jaw member includes a second sensor configured to detect the position of the code embedded portion of the surgical staple in a formed state.
8. The surgical stapling instrument according to claim 7 , wherein the second sensor is configured to detect the position of the code embedded portion of the surgical staple when the surgical staple is in contact with the second jaw member.
9. The surgical stapling instrument according to claim 7 , wherein the code embedded portion of the surgical staple aligns with the second sensor after a predetermined formation of the surgical staple.
10. The surgical stapling instrument according to claim 7 , wherein the second jaw member defines a concavity and the second sensor is disposed adjacent the concavity.
11. The surgical stapling instrument according to claim 10 , wherein the second sensor is exposed to the concavity.
12. The surgical stapling instrument according to claim 11 , wherein the second sensor is in direct contact with the code embedded portion after a predetermined formation of the surgical staple.
13. A surgical stapling instrument comprising:
a surgical staple including a code embedded portion; and
a tool assembly including a cartridge assembly and an anvil assembly selectively positionable relative to the cartridge assembly, the anvil assembly including a first sensor configured to detect a position of the code embedded portion of the surgical staple in a formed state.
14. The surgical stapling instrument according to claim 13 , wherein the first sensor is configured to detect the position of the code embedded portion of the surgical staple when the surgical staple is in contact with the anvil assembly.
15. The surgical stapling instrument according to claim 14 , wherein the cartridge assembly defines a retention channel for receiving the surgical staple therein, the second sensor exposed to the retention channel.
16. The surgical stapling instrument according to claim 15 , wherein the second sensor is in direct contact with the code embedded portion when the surgical staple is properly loaded in the retention channel prior to formation of the surgical staple.
17. The surgical stapling instrument according to claim 13 , wherein the surgical staple includes a backspan and a pair of legs extending from the backspan, at least one leg of the pair of legs including the code embedded portion.
18. The surgical stapling instrument according to claim 13 , wherein the cartridge assembly includes a second sensor configured to detect a position of the code embedded portion of the surgical staple in an unformed state.
19. A surgical stapling instrument comprising:
a surgical staple including a code embedded portion; and
a tool assembly including a first jaw member and a second jaw member selectively positionable relative to the first jaw member, the first jaw member including a first sensor configured to detect a position of the code embedded portion of the surgical staple, the second jaw member including a second sensor configured to detect the position of the code embedded portion of the surgical staple in a formed state.
