Abstract

Disclosed are surgical instruments configured to control therapeutic energy application to tissue based on cartridge and tissue parameters.

Claims (64)

1 . A surgical instrument, comprising:

a shaft;

an end effector, comprising:

a first jaw;

a second jaw movable relative to the first jaw between in a closure motion to grasp tissue therebetween;

an anvil, comprising:

a row of staple pockets; and

a first electrode assembly, wherein the first electrode assembly comprises a row of first segmented electrodes;

a cartridge, wherein the cartridge comprises a cartridge body, comprising:

a cartridge deck;

a row of staple cavities defined in the cartridge deck, wherein the row of staple cavities comprises staples deformable against the row of staple pockets in a firing motion; and

a second electrode assembly, wherein the second electrode assembly comprises a row of second segmented electrodes;

a motor configured to effect a rotation of the end effector relative to the shaft about a longitudinal access extending centrally through the shaft;

a motor circuit configured to supply power to the motor;

a control circuit configured to:

cause a sub-therapeutic signal to be provided to the end effector;

detect an impedance between the first electrode assembly and the second electrode assembly in response to the sub-therapeutic signal; and

selecting a parameter of the rotation of the end effector based on the impedance.

2 . The surgical instrument of claim 1 , wherein selecting the parameter of the rotation of the end effector comprises selecting a parameter of the power supplied to the motor to effect the rotation of end effector.

3 . The surgical instrument of claim 1 , wherein the impedance is indicative of a tissue presence between the first jaw and the second jaw.

4 . The surgical instrument of claim 3 , wherein selecting the power parameter of the motor comprises reducing a previously-set power parameter of the motor.

5 . The surgical instrument of claim 1 , wherein the control circuit is configured to detect a closure state of the end effector.

6 . The surgical instrument of claim 5 , wherein the control circuit is configured to select the parameter of the rotation of the end effector based on the impedance and the closure state of the end effector.

7 . The surgical instrument of claim 1 , wherein the control circuit is configured to detect a firing state of the end effector.

8 . The surgical instrument of claim 7 , wherein the control circuit is configured to select the parameter of the rotation of the end effector based on the impedance and the firing state of the end effector.

9 . A surgical instrument, comprising:

a first jaw;

a second jaw movable relative to the first jaw in a closure motion to grasp tissue therebetween;

an anvil, comprising:

a row of staple pockets; and

a first electrode assembly, wherein the first electrode assembly comprises a row of first segmented electrodes;

a cartridge, wherein the cartridge comprises a cartridge body, comprising:

a cartridge deck;

a row of staple cavities defined in the cartridge deck, wherein the row of staple cavities comprises staples deformable against the row of staple pockets in a firing motion; and

a second electrode assembly, wherein the second electrode assembly comprises a row of second segmented electrodes;

a control circuit configured to:

detect a tissue parameter;

detect a cartridge parameter; and

select a radio-frequency (RF) energy treatment for sealing the tissue based on the cartridge parameter and the tissue parameter.

10 . The surgical instrument of claim 9 , wherein the tissue parameter a tissue thickness.

11 . The surgical instrument of claim 9 , wherein the cartridge parameter is a cartridge type.

12 . The surgical instrument of claim 9 , wherein the cartridge parameter is a staple height.

13 . The surgical instrument of claim 9 , wherein the radio-frequency (RF) energy treatment is selected form radio-frequency (RF) energy treatments with different sealing times or different power levels.

14 . The surgical instrument of claim 9 , wherein the cartridge parameter represents a gap between first jaw and the second jaw.

15 . A surgical instrument, comprising:

an end effector, comprising:

a first jaw;

a second jaw movable relative to the first jaw in a closure motion to grasp tissue therebetween;

an anvil, comprising:

a row of staple pockets; and

a first electrode assembly, wherein the first electrode assembly comprises a row of first segmented electrodes;

a cartridge, wherein the cartridge comprises a cartridge body, comprising:

a cartridge deck;

a row of staple cavities defined in the cartridge deck, wherein the row of staple cavities comprises staples deformable against the row of staple pockets in a firing motion; and

a second electrode assembly, wherein the second electrode assembly comprises a row of second segmented electrodes; and

a control circuit configured to:

apply a therapeutic energy to the tissue to seal the tissue;

detect a tissue sealing inconsistency; and

adjust a stapling parameter to compensate for the tissue sealing inconsistency.

16 . The surgical instrument of claim 15 , wherein the tissue sealing inconsistency comprises a short circuit.

17 . The surgical instrument of claim 15 , wherein the control circuit is configured to alternate applying the therapeutic energy and deploying the staples along a length of the end effector.

18 . The surgical instrument of claim 17 , wherein the control circuit is configured to cause applying the therapeutic energy to lead deploying the staples.

19 . The surgical instrument of claim 15 , wherein adjusting the stapling parameter comprises changing a closure parameter of the end effector.

20 . The surgical instrument of claim 19 , wherein adjusting the stapling parameter comprises changing a firing parameter of the end effector.
