Abstract

A surgical robotic system includes a control tower having a first connector coupled to a first controller; and a movable robotic arm cart having a robotic arm and a second connector coupled to a second controller, the second connector being configured to couple to the first connector through a cable. The second controller being configured to transmit an identification signal having identification information of the movable robotic arm cart to the first controller to initialize the movable robotic arm cart for operation with the control tower.

First claim

What is claimed is:

1. A surgical robotic system comprising:
a control tower having a first connector coupled to a first controller; and
a movable robotic arm cart having a robotic arm and a second connector coupled to a second controller, the second connector being configured to couple to the first connector through a cable,
wherein the first controller is configured to assign a unique identification number to the movable robotic arm cart upon initial connection of the movable robotic arm cart to the control tower via the cable coupled to the first connector and the second connector, and the second controller being configured to continuously transmit an identification signal having identification information of the movable robotic arm cart including the assigned identification number to the first controller to initialize the movable robotic arm cart for operation with the control tower, and
wherein the first controller is further configured to continuously receive the transmitted identification signal having the identification information, and compare the identification information to the assigned identification number to determine whether the identification information and the assigned identification number are the same to confirm that a connection between the movable robotic arm cart and the control tower is functional.

2. The surgical robotic system of claim 1 , further comprising:
an operating console coupled to the control tower and configured to transmit a control signal to the control tower, wherein the control tower is configured to, based on the control signal from the operating console, control the robotic arm after the movable robotic arm cart is initialized.

3. The surgical robotic system of claim 1 , wherein the first controller is configured to receive the identification signal from the second controller and, based on the identification signal, transmit a response signal to indicate that the first controller is configured to be coupled to the second controller.

4. The surgical robotic system of claim 1 , wherein the first controller is configured to receive the identification signal from the second controller and, based on the identification signal, transmit a response signal to indicate that the first controller is not configured to be coupled with the second controller.

5. The surgical robotic system of claim 4 , wherein the second connector includes a plurality of contacts, a subset of which are reserved for communication by the second controller that, in response to receiving a power signal, transmit a predetermined identification signal.

6. The surgical robotic system of claim 5 , wherein the identification signal is formed by a predetermined configuration of high and low signals, each of the high and low signals corresponding to a specific pin from among the plurality of contacts, the combination of the contacts and the high and low signals being associated with the identification signal.

7. The surgical robotic system of claim 5 , wherein the contacts reserved for communication of the identification signal are general purpose input/output (GPIO) contacts.

8. The surgical robotic system of claim 7 , wherein the GPIO contacts are at least single fault tolerant.

9. The surgical robotic system of claim 7 , wherein the GPIO includes four contacts, with two contacts of the four contacts configured to output a high signal and two contacts of the four contacts configured to output a low signal for identification of the movable robotic arm cart by the control tower.

10. A method of identifying device mismatches in a surgical robotic system between a movable robotic arm cart and a control tower, the method comprising:
assigning a unique identification number at a first controller of a control tower to a movable robotic arm cart upon initial connection of the movable robotic arm cart to the control tower via a cable coupled to a first connector of the control tower and a second connector of the robotic arm cart;
continuously transmitting from the second connector coupled to a second controller of the movable robotic arm cart, an identification signal based on the identification number assigned to the movable robotic arm cart;
continuously receiving the identification signal at the first connector coupled to the first controller of the control tower, the first connector operably coupled to the second connector by the cable; and
continuously determining, at the first controller, whether the identification signal matches the identification number to confirm that a connection between the movable robotic arm cart and the control tower is functional.

11. The method of claim 10 , further comprising:
transmitting a control signal from the control tower to the movable robotic arm cart to initialize operation of the movable robotic arm cart by the control tower based on the determination by the first controller that the identification signal matches the identification number.

12. The method of claim 10 , further comprising transmitting an indication signal from the control tower to an operating console having a display, the indication signal causing the display to indicate a match or a mismatch based on determining whether the identification signal matches the identification number.

13. The method of claim 12 , wherein determining includes comparing the identification signal to indexed identification information stored in a memory of the second controller.

14. The method of claim 13 , wherein the first connector and the second connector include a plurality of contacts that operate as general purpose input/output (GPIO) contacts for communicating with each other.

15. The method of claim 14 , wherein the first controller of the control tower is configured to output an indication of the mismatch via the control tower or the movable robotic arm cart.

16. The method of claim 12 , wherein causing an indication to be output includes displaying at least one of a serial number, model number, or connector number associated with the movable robotic arm cart via a display device of the operating console.

17. A surgical robotic system comprising:
a control tower having a first connector coupled to a first controller; and
a plurality of movable robotic arm carts each having a second connector coupled to a second controller, the second connector being configured to couple to the first connector through a cable, wherein the first controller is configured to assign a unique identification number to each movable cart of the plurality of movable robotic arm carts upon initial connection of each movable cart of the plurality of movable robotic arm carts to the control tower via the cable coupled to the first connector and the second connector, and the second controller is configured to continuously transmit an identification signal having identification information of each movable cart of the plurality of movable robotic arm carts including the assigned identification number to the first controller, which is further configured to compare the assigned identification number to the identification information to determine whether the identification information and the assigned identification number are the same to confirm that a connection between each movable robotic arm cart of the plurality of the movable robotic arm carts and the control tower is functional.

18. The surgical robotic system of claim 17 , wherein the first controller is configured to receive the identification signal from the second controller and, based on the identification signal, transmit a response signal t
