Abstract

A medical tool comprising an electromechanical driver and a surgical instrument attachment for use in invasive surgery, including a handle coupled to a flexible sheath which is in turn coupled to a surgical attachment. The handle of the driver includes the electromechanical driver and at least one processor element which controls the actions of the electromechanical driver, and therefore the application elements of the surgical attachment, based on information relayed between the processor element and remotely activatable sensor assemblies in the surgical instrument attachment.

Claims

1. A surgical system, comprising:

a handheld electromechanical driver, including;

a handle portion;

at least one motor supported in the handle portion; and

a processor in communication with the at least one motor; and

a surgical attachment, selectively coupleable to the handheld electromechanical driver, including;

an anvil portion;

a staple, blade, sensor, and reservoir (SBSR) portion coupleable to the anvil portion; and

a memory unit included within the SBSR portion configured to store identity information and status information of the surgical attachment,

wherein, when the surgical attachment is coupled to the handheld electromechanical driver, the processor of the handheld electromechanical driver queries the memory unit of the surgical attachment regarding the identity information and status information.

2. The surgical system according to claim 1, wherein the surgical attachment is an interchangeable surgical attachment.

3. The surgical system according to claim 1, wherein the surgical attachment is an anastomosing, resecting, and stapling attachment.

4. The surgical system according to claim 1, wherein the identity information includes at least one of size, diameter, shape, length, and stapling arrangement of the surgical attachment.

5. The surgical system according to claim 1, wherein the status information includes at least one of functionality and usage history of the surgical attachment.

6. The surgical system according to claim 1, wherein the SBSR portion includes drive elements for moving the anvil portion.

7. The surgical system according to claim 1, wherein the SBSR portion includes motive elements for driving a blade and staples through tissue.

8. The surgical system according to claim 1, wherein the identity information and the status information are displayed on a remote display coupled to the handle portion.

9. The surgical system according to claim 1, wherein the identity information and the status information are displayed on a display integrated on the handle portion.

10. The surgical system according to claim 1, wherein the processor establishes when the handheld electromechanical driver is activatable based on the identity information and the status information received.

11. A surgical attachment for use in a surgical system having an electromechanical driver including a processor, the surgical attachment including:

an anvil portion;

a staple, blade, sensor, and reservoir (SBSR) portion coupleable to the anvil portion; and

a memory unit included within the SBSR portion configured to store identity information and status information of the surgical attachment,

wherein, when the surgical attachment is coupled to the electromechanical driver, the processor queries the memory unit of the surgical attachment regarding the identity information and status information.

12. The surgical attachment according to claim 11, wherein the surgical attachment is an interchangeable anastomosing, resecting, and stapling attachment.

13. The surgical attachment according to claim 11, wherein the identity information includes at least one of size, diameter, shape, length, and stapling arrangement of the surgical attachment.

14. The surgical attachment according to claim 11, wherein the status information includes at least one of functionality and usage history of the surgical attachment.

15. The surgical attachment according to claim 11, wherein the SBSR portion includes drive elements for moving the anvil portion.

16. The surgical attachment according to claim 11, wherein the SBSR portion includes motive elements for driving a blade and staples through tissue.

17. The surgical attachment according to claim 11, wherein the identity information and the status information are displayed on a remote display coupled to a handle portion of the surgical system.

18. The surgical attachment according to claim 11, wherein the identity information and the status information are displayed on a display integrated on a handle portion of the surgical system.

19. The surgical attachment according to claim 11, wherein the processor establishes when the electromechanical driver is activatable based on the identity information and the status information received.

20. The surgical attachment according to claim 11, further comprising a sensor assembly, the processor of the electromechanical driver configured to receive data from the sensor assembly.
