Abstract

A debris clearing system is provided that includes a tool having a suctioning intake positioned on an axis of the tool. A controller actuates the suctioning intake along the length of the axis of the tool. The suctioning intake is actuated while the tool is being operated and proximal to a surgical site on a patient's anatomy. A method of use is also provided for suctioning debris from a surgical field during a procedure.

First claim

The invention claimed is:

1. A debris clearing system for clearing of debris created during a surgical procedure at a surgical site on a patient's anatomy comprising:
a tool connected to a robotic surgical system;
a suctioning intake positioned on an axis of said tool;
a pre-operative surgical plan residing on the robotic surgical system and having instructions for a controller to automatically adjust a position of said suctioning intake relative to the patient's anatomy as the controller automatically adjusts the position of said suctioning intake relative to a working portion of said tool; and
said controller configured to actuate said suctioning intake along the axis of said tool while said tool is being operated to automatically clear the debris created during the surgical procedure.

2. The debris clearing system of claim 1 wherein said tool is at least one of a drill bit, cutter, burr, saw blade, shears, forceps, dissectors, cautery hook, cautery spatula, scissors, retractors, or graspers.

3. The debris clearing system of claim 1 wherein said controller further comprises a microprocessor, a storage medium, and a series of components to actuate and measure the movement and position of said suctioning intake.

4. The debris clearing system of claim 3 wherein said series of components further comprise one or more of gears, worm gears, screws, wheels and axles, cams, actuators, motors, step motors, micro-motors, servo-motors, encoders, a transmitter, a receiver, a transceiver, and sensors.

5. The debris clearing system of claim 4 further comprising an elongate member, said elongate member fixedly attached to said suctioning intake and movably connected to said controller for the actuation of said suctioning intake; and
wherein said elongated member is configured to be actuated by at least one of said gears, worm gears, screws, wheels and axles, cams, actuators, motors, step motors, micro-motors, servo-motors, encoders.

6. The debris clearing system of claim 4 wherein said sensors further comprise at least one of contact sensors, force sensors, proximity sensors, distance measurement sensors, acoustic sensors, electric sensors, position sensors, pressure sensors, or any combination thereof.

7. The debris clearing system of claim 4 further comprising a fiber optic cable between said transceiver and said suctioning intake, where a series of pulses sent along said fiber optic cable generate a reflected signal from the surgical site used to determine a distance between said suctioning intake and the surgical site.

8. The debris clearing system of claim 1 further comprising one or more hollow tubes, where a distal end of said one or more hollow tubes is incorporated with or attached to said suctioning intake to create a port between said suctioning intake and a proximal end of said one or more hollow tubes; and
wherein said proximal end of said one or more hollow tubes is configured for attachment to an external device.

9. The debris clearing system of claim 8 wherein said external device is a vacuum.

10. The debris clearing system of claim 8 wherein said external device is a fluid pump that directs one or more fluids to said suctioning intake.

11. The debris clearing system of claim 10 wherein said one or more fluids comprise water, saline, therapeutic agents, sanitization agents, gas, or combinations thereof.

12. The debris clearing system of claim 10 wherein said fluid pump further comprises an ultrasonic transducer.

13. The debris clearing system of claim 10 wherein said fluid pump further comprises a fluid output port and a suctioning input port for collecting an injected fluid with a series of collected debris from the surgical site.

14. The debris clearing system of claim 1 wherein said suctioning intake further comprises an enclosure, said enclosure having a wall with an inner void to trap debris.

15. The debris clearing system of claim 14 wherein said enclosure and said wall are made of a flexible material.

16. The debris clearing system of claim 14 wherein said wall further comprises a brush structure with a set of multiple fibers extending from said suctioning intake.

17. The debris clearing system of claim 1 wherein said suctioning intake is configured as a hollow tube that movably slides over said tool; and
wherein during a procedure, the hollow tube is configured to be actuated along said tool until said hollow tube passes over the working portion of said tool to clear debris from the surgical site.

18. A method of using the debris clearing system of claim 1 comprising:
positioning said tool at the surgical site;
actuating said suctioning intake along said tool towards the surgical site; and

wherein said suctioning intake is actuated while said tool is being operated.
