Abstract

Claims (34)

1 . A surgical stapling system, comprising:

an end effector comprising a first jaw and a second jaw, wherein the first jaw is movable from an open position towards a clamped position;

a motor-driven firing bar movable when a firing motion is applied thereto;

a sensor to monitor a stapling condition; and

a control circuit to:

receive a sensor signal from the sensor indicative of the stapling condition;

initiate a timer based on the sensor signal; and

transmit a firing signal to generate the firing motion based on the timer satisfying a threshold.

2 . The surgical stapling system of claim 1 , wherein the threshold is selected to delay the firing motion to stabilize patient tissue.

3 . The surgical stapling system of claim 2 , further comprising a display, wherein the control circuit is to cause the display to indicate that the motor-driven firing bar is being prevented from moving through the firing motion before the timer satisfies the threshold.

4 . The surgical stapling system of claim 3 , wherein the display comprises a light emitting diode (LED) display.

5 . The surgical stapling system of claim 4 , and wherein one of the first jaw and the second jaw is configured to removably receive a staple cartridge comprising a plurality of ejectable staples.

6 . The surgical stapling system of claim 5 , further comprising the staple cartridge, wherein the firing motion of the motor-driven firing bar is to eject the plurality of ejectable staples from the staple cartridge.

7 . The surgical stapling system of claim 6 , further comprising a motor to generate the firing motion, wherein the control circuit is further to cause the motor to generate the firing motion based on the timer satisfying the threshold.

8 . The surgical stapling system of claim 7 , wherein the timer comprises an on-delay timer.

9 . The surgical stapling system of claim 1 , wherein the threshold corresponds to a pre-set time delay.

10 . The surgical stapling system of claim 1 , wherein the threshold corresponds to a selectively adjustable delay.

11 . The surgical stapling system of claim 1 , wherein the threshold comprises a force threshold.

12 . A surgical stapling system, comprising:

an end effector comprising a first jaw and a second jaw, wherein the first jaw is movable from an open position towards a clamped position, and wherein one of the first jaw and the second jaw is configured to removably receive a staple cartridge comprising a plurality of staples;

a motor-driven firing driver movable when a firing motion is applied thereto;

a force sensor; and

a control circuit to:

receive a sensor signal from the force sensor;

initiate a timer based on the sensor signal; and

transmit a firing signal to generate the firing motion based on the timer satisfying a threshold.

13 . The surgical stapling system of claim 12 , further comprising the staple cartridge, wherein the firing motion of the motor-driven firing driver is to eject the plurality of staples from the staple cartridge.

14 . The surgical stapling system of claim 13 , further comprising a motor to generate the firing motion, wherein the control circuit is further to cause the motor to generate the firing motion based on the timer satisfying the threshold.

15 . The surgical stapling system of claim 14 , wherein the threshold corresponds to a delay for stabilizing patient tissue.

16 . The surgical stapling system of claim 15 , wherein the timer comprises an on-delay timer.

17 . The surgical stapling system of claim 15 , wherein the threshold corresponds to a pre-set time delay.

18 . The surgical stapling system of claim 15 , wherein the threshold corresponds to a selectively adjustable delay.

19 . The surgical stapling system of claim 12 , further comprising a display, wherein the control circuit is to cause the display to indicate that a status of the timer.

20 . The surgical stapling system of claim 12 , wherein the sensor signal corresponds to a clamping force.
