Surgical instrument with firing lockout
A surgical instrument. The surgical instrument has an end effector and a trigger in communication with the end effector. The surgical instrument also has a first sensor and an externally accessible memory device in communication with the first sensor. The first sensor has an output that represents a first condition of either the trigger or the end effector. The memory device is configured to record the output of the first sensor. In various embodiments, memory device may include an output port and/or a removable storage medium.
1. A surgical instrument system, comprising:
an end effector comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto, wherein said end effector is configured to receive a staple cartridge removably installed therein, and wherein said staple cartridge comprises a sled drivable from a proximal, unfired position toward a distal position to eject staples from said staple cartridge;
a firing beam movable toward said distal end when a firing motion is applied thereto to drive said sled toward said distal position;
a motor configured to generate said firing motion,
a control circuit to determine that said staple cartridge is in a ready-to-fire configuration based on detecting that said sled is in said proximal, unfired position.
2. The surgical instrument system of claim 1 , wherein said control circuit is to determine that said staple cartridge is spent based on detecting that said sled is not in said proximal, unfired position.
3. The surgical instrument system of claim 2 , further comprising a cartridge condition sensor positioned to directly sense the presence of said sled in said proximal, unfired position.
4. The surgical instrument system of claim 1 , wherein said control circuit is to determine that said staple cartridge is installed in said end effector based on detecting that said sled is in said proximal, unfired position.
5. The surgical instrument system of claim 1 , wherein said control circuit is to detect that said staple cartridge is not installed in said end effector.
6. The surgical instrument system of claim 5 , wherein said control circuit is to prevent said motor from generating said firing motion based on detecting that said staple cartridge is not installed in said end effector.
7. The surgical instrument system of claim 6 , wherein said control circuit is to:
determine that said end effector is in a partially clamped configuration; and
prevent said motor from generating said firing motion based on determining that said end effector is in said partially clamped configuration.
8. The surgical instrument system of claim 1 , further comprising a force sensor to detect a clamping force of said end effector, wherein said end effector comprises:
a first jaw; and
a second jaw movable relative to said second jaw to move said end effector between said open configuration and said closed configuration.
9. A surgical instrument system, comprising:
an end effector comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto, wherein said end effector is configured to receive a staple cartridge removably installed therein, and wherein said staple cartridge comprises a sled drivable from a proximal, unfired position toward a distal position to eject staples from said staple cartridge;
a firing beam movable toward said distal end when a firing motion is applied thereto to drive said sled toward said distal position;
a motor configured to generate said firing motion; and
a control circuit to determine that said staple cartridge is not in a ready-to-fire configuration based on detecting that said sled is not in said proximal, unfired position.
10. The surgical instrument system of claim 9 , wherein said control circuit is to determine that said staple cartridge is spent based on detecting that said sled is not in said proximal, unfired position.
11. The surgical instrument system of claim 10 , further comprising a cartridge condition sensor positioned to directly sense the presence of said sled in said proximal, unfired position.
12. The surgical instrument system of claim 9 , wherein said control circuit is to determine that said staple cartridge is installed in said end effector based on detecting that said sled is in said proximal, unfired position.
13. The surgical instrument system of claim 9 , wherein said control circuit is to detect that said staple cartridge is not installed in said end effector.
14. The surgical instrument system of claim 13 , wherein said control circuit is to prevent said motor from generating said firing motion based on detecting that said staple cartridge is not installed in said end effector.
15. The surgical instrument system of claim 14 , wherein said control circuit is to:
determine that said end effector is in a partially clamped configuration; and
prevent said motor from generating said firing motion based on determining that said end effector is in said partially clamped configuration.
16. The surgical instrument system of claim 9 , further comprising a force sensor to detect a clamping force of said end effector, wherein said end effector comprises:
a first jaw; and
a second jaw movable relative to said second jaw to move said end effector between said open configuration and said closed configuration.
17. A surgical instrument system, comprising:
an end effector comprising a distal end, wherein said end effector is movable between an open configuration and a closed configuration when a closing motion is applied thereto, wherein said end effector is configured to receive a staple cartridge removably installed therein, and wherein said staple cartridge comprises a sled drivable from a proximal, unfired position toward a distal position to eject staples from said staple cartridge;
a firing beam movable toward said distal end when a firing motion is applied thereto to drive said sled toward said distal position;
a motor configured to generate said firing motion; and
a control circuit to determine that said staple cartridge is spent based on detecting that said sled is not in said proximal, unfired position.
18. The surgical instrument system of claim 17 , further comprising a cartridge condition sensor to directly sense the presence of said sled in said proximal, unfired position.
19. The surgical instrument system of claim 17 , wherein said control circuit is to:
determine that said end effector is in a partially clamped configuration; and
prevent said motor from generating said firing motion based on determining that said end effector is in said partially clamped configuration.
20. The surgical instrument system of claim 17 , further comprising a force sensor to detect a clamping force of said end effector, wherein said end effector comprises:
a first jaw; and
a second jaw movable relative to said second jaw to move said end effector between said open configuration and said closed configuration.
