Abstract

A surgical system includes a surgical instrument, an end effector, a control circuit, and a sensor configured to transmit a sensor signal indicative of a closure parameter of the end effector. The control circuit is configured to adjust a closure rate of change parameter and the closure threshold parameter based on perioperative information received from one or more data sources and a sensor signal received from the sensor.

First claim

What is claimed is:

1. A surgical system comprising:
a surgical instrument, wherein the surgical instrument comprises:
an end effector comprising:
a first jaw; and
a second jaw, wherein the first jaw is configured to move relative to the second jaw;

a motor configured to move the first jaw relative to the second jaw according to a closure rate of change parameter and a closure threshold parameter; and
a sensor configured to transmit a sensor signal indicative of a closure parameter of the end effector; and

a control circuit communicatively coupled to the sensor, wherein the control circuit is configured to:
receive perioperative information, wherein the perioperative information comprises one or more of a perioperative disease, a perioperative treatment, and a type of a surgical procedure;
receive the sensor signal from the sensor; and
determine an adjustment to the closure rate of change parameter and the closure threshold parameter based on the perioperative information and the sensor signal.

2. The surgical system of claim 1 , wherein the control circuit is further configured to determine a characteristic of a tissue to be treated by the surgical instrument based on one or more of the perioperative information and the sensor signal.

3. The surgical system of claim 2 , wherein the tissue characteristic comprises one or more of a tissue type characteristic, muscular characteristic, vasculature characteristic, water content characteristic, stiffness characteristic, and thickness characteristic.

4. The surgical system of claim 1 , wherein the control circuit is further configured to change a speed of the motor based on the determined adjustment to the closure rate of change parameter and the closure threshold parameter.

5. The surgical system of claim 1 , wherein the control circuit is further configured to generate an alert based on an inconsistency between a type of the surgical instrument and one or more of the perioperative information and the sensor signal.

6. The surgical system of claim 1 , wherein the perioperative information further comprises one or more of a type of a tissue to be treated by the surgical instrument, a tissue characteristic, a clinician history, and a type of staple cartridge for use with the surgical instrument.

7. The surgical system of claim 1 , wherein:
the closure threshold parameter is a maximum closure force threshold; and
the control circuit is further configured to disable the motor for a predetermined period of time based on reaching the maximum closure force threshold.

8. A surgical system comprising:
a surgical hub configured to receive perioperative information transmitted from a remote database of a cloud computing system, wherein the surgical hub is communicatively coupled to the cloud computing system; and
a surgical instrument communicatively coupled to the surgical hub, wherein the surgical instrument comprises:
an end effector comprising:
a first jaw; and
a second jaw, wherein the first jaw is configured to move relative to the second jaw;
a motor configured to move the first jaw relative to the second jaw according to a closure rate of change parameter and a closure threshold parameter of a closure control program received from the surgical hub; and

a sensor configured to transmit a sensor signal indicative of a closure parameter of the end effector; and

wherein the surgical hub is further configured to:
receive the sensor signal from the sensor; and
determine an adjustment to the closure rate of change parameter and the closure threshold parameter based on the perioperative information and the sensor signal.

9. The surgical system of claim 8 , wherein:
the closure control program is a first closure control program;
the surgical hub is further configured to transmit a second closure control program to the surgical instrument; and
the second closure control program defines the adjustment to the closure rate of change parameter and the adjustment to the closure threshold parameter.

10. The surgical system of claim 9 , wherein:
the cloud computing system is configured to transmit the second closure control program to the surgical hub; and
the adjustment to the closure rate of change parameter and the adjustment to the closure threshold parameter of the second closure control program is adjusted based on the perioperative information.

11. The surgical system of claim 9 , wherein the surgical hub is further configured to change a speed of the motor based on the determined adjustment to the closure rate of change parameter and the closure threshold parameter.

12. The surgical system of claim 8 , wherein the surgical instrument is configured to generate an alert based on an inconsistency between a type of the surgical instrument and one or more of the perioperative information and the sensor signal.

13. The surgical system of claim 8 , wherein:
the closure threshold parameter is a maximum closure force threshold; and
the surgical hub is further configured to disable the motor for a predetermined period of time based on reaching the maximum closure force threshold.

14. The surgical system of claim 13 , wherein the perioperative information comprises one or more of a perioperative disease, a perioperative treatment, a type of a surgical procedure, a clinician history, a type of the surgical instrument, a type of a tissue being treated by the surgical instrument, and a characteristic of the tissue.

15. A surgical instrument comprising:
an end effector comprising:
a first jaw; and
a second jaw, wherein the first jaw is configured to move relative to the second jaw;

a motor configured to move the first jaw relative to the second jaw according to a closure rate of change parameter and a closure threshold parameter of a first closure control program received from a surgical hub;
a sensor configured to transmit a sensor signal indicative of a closure parameter of the end effector; and
a control circuit communicatively coupled to the sensor and the motor, wherein the control circuit is configured to:
receive the sensor signal from the sensor; and
determine an adjustment to the closure rate of change parameter and the closure threshold parameter based on perioperative information and the sensor signal.

16. The surgical instrument of claim 15 , wherein the surgical instrument is configured to generate an alert based on an inconsistency between a type of the surgical instrument and one or more of the perioperative information and the sensor signal.

17. The surgical instrument of claim 15 , wherein the control circuit is further configured to:
switch from the first closure control program to a second closure control program received from a cloud computing system; and
change a speed of the motor based on the second closure control program.

18. The surgical instrument of claim 15 , wherein the control circuit is further configured to determine a characteristic and a type of a tissue to be treated by the surgical instrument based on one or more of the perioperative information and the sensor signal.

19. The surgical instrument of claim 15 , wherein the closure threshold parameter is a maximum closure force threshold.

20. The surgical instrument of claim 19 , wherein the control circuit is further configured to disable the motor for a predetermined period of time based on reaching the maximum closure force threshold.

21. A surgical system, comprising:
a surgical instrument, comprising:
an end effector comprisi
