Abstract

Claims (39)

1. A system, comprising:

a surgical stapler, comprising a motor and a knife drivable by the motor;

a control circuit to:

control the motor to perform a first firing stroke according to a firing parameter;

determine a firing force for the first firing stroke;

automatically adapt the firing parameter based on the firing force; and

control the motor to perform a second firing stroke according to the automatically adapted firing parameter.

2. The system of claim 1 , wherein the control circuit is to automatically adapt the firing parameter based on a range of firing parameters.

3. The system of claim 2 , wherein the control circuit is to automatically adapt the firing parameter by applying the firing force for the first firing stroke to a machine learning model.

4. The system of claim 3 , wherein the machine learning model is trained based on historic data collected during previous uses of the surgical stapler.

5. The system of claim 4 , wherein the control circuit is to:

determine an identity of a user of the surgical stapler; and

automatically adapt the firing parameter based on the identity of the user.

6. The system of claim 2 , wherein the control circuit is to:

determine an identity of a user of the surgical stapler; and

automatically adjust the range based on the identity of the user.

7. The system of claim 2 , wherein the control circuit is to receive a user input for manually adjusting the range.

8. The system of claim 7 , further comprising a graphical user interface comprising a touch screen to receive the user input for manually adjusting the range.

9. The system of claim 8 , wherein the graphical user interface is to display a user-adjustable slider for receiving the user input.

10. The system of claim 9 , wherein the firing parameter is a firing speed, and wherein the range comprises a minimum firing speed and a maximum firing speed.

11. The system of claim 2 , wherein the control circuit is to pause the second firing stroke based on a firing force for the second firing stroke exceeding a predetermined threshold.

12. The system of claim 11 , wherein the firing parameter comprises a firing pause duration, and wherein the range comprises a minimum firing pause duration and a maximum firing pause duration.

13. A method for automatically adapting a firing parameter of a surgical stapler, the method comprising:

setting, by a control circuit, a range for a firing parameter;

controlling, by a control circuit, a motor to perform a first firing stroke;

determining, by the control circuit, a firing force for the first firing stroke;

automatically adapting, by the control circuit, the firing parameter within the range based on the firing force; and

controlling, by the control circuit, the motor to perform a second firing stroke according to the automatically adapted firing parameter.

14. The method of claim 13 , wherein automatically adapting the firing parameter comprises applying the firing force for the first firing stroke to a machine learning model.

15. The method of claim 13 , further comprising:

determining, by the control circuit, an identity of a user of a surgical stapler; and

automatically, by the control circuit, adapting the firing parameter based on the identity of the user.

16. The method of claim 13 , further comprising:

determining, by the control circuit, an identity of a user of the surgical stapler; and

automatically, by the control circuit, adjusting the range based on the identity of the user.

17. The method of claim 13 , further comprising receiving, by the control circuit, a user input for manually adjusting the range.

18. The method of claim 13 , further comprising receiving, by the control circuit, a user input for manually adjusting a number of firing speeds during a firing stroke.

19. The method of claim 13 , wherein the firing parameter comprises a firing speed, wherein the range comprises a minimum firing speed and a maximum firing speed, and wherein automatically adapting, by the control circuit, the firing parameter comprises adapting the firing speed between the minimum firing speed and the maximum firing speed based on the firing force.

20. The method of claim 13 , wherein the firing parameter comprises a firing pause duration, wherein the range comprises a minimum firing pause duration and a maximum firing pause duration, and wherein automatically adapting, by the control circuit, the firing parameter comprises adapting the firing pause duration between the minimum firing speed and the maximum firing speed based on the firing force.
