  "abstract": "Devices, systems, and methods for drilling an anatomical element are provided. A drill bit may comprise a coaxial hollow shaft in communication with a plurality of apertures disposed on a surface of the drill bit. A fluid inlet may be in fluid communication with the coaxial hollow shaft via a selectively openable valve. The fluid inlet may be configured to receive pressurized fluid. When the valve is opened, the pressurized fluid may be released into the coaxial hollow shaft, and when at least one of the plurality of apertures is not blocked, the pressurized fluid may be released through the at least one aperture of the plurality of apertures.",
  "claims": [
    "1. A device for drilling an anatomical element comprising: a drill bit comprising a coaxial hollow shaft in communication with at least one aperture disposed on a surface of the drill bit; and a fluid inlet in fluid communication with the coaxial hollow shaft via a selectively openable valve, the fluid inlet configured to receive pressurized fluid, wherein when the selectively openable valve is opened, the pressurized fluid is released into the coaxial hollow shaft and through the at least one aperture.",
    "2. The device of claim 1, further comprising: at least one processor; and a memory storing instructions for execution by the at least one processor that, when executed, cause the at least one processor to: cause the drill bit to rotate and advance, cause the selectively openable valve to open, and monitor a pressure of the pressurized fluid via a pressure sensor in fluid communication with the coaxial hollow shaft.",
    "3. The device of claim 2, wherein the memory stores additional instructions for execution by the at least one processor that, when executed, further cause the at least one processor to: receive sensor data from the pressure sensor, and compare the sensor data to a predetermined threshold.",
    "4. The device of claim 3, wherein the memory stores additional instructions for execution by the at least one processor that, when executed, further cause the at least one processor to: cause the drill bit to advance when the pressure of the pressurized fluid is above the predetermined threshold.",
    "5. The device of claim 2, wherein the memory stores additional instructions for execution by the at least one processor that, when executed, further cause the at least one processor to: open the selectively openable valve once the drill bit has been activated for a predetermined period of time, the drill bit has reached a predetermined drilling depth, or a predetermined drilling time has passed.",
    "6. The device of claim 1, wherein the at least one aperture comprises a plurality of apertures, and wherein the pressurized fluid is released into the coaxial hollow shaft when at least one of the plurality of apertures is unblocked.",
    "7. The device of claim 1, wherein a first aperture of the at least one aperture is disposed on a tip of the drill bit and a second aperture of the at least one aperture is disposed at an angle to an axis of the coaxial hollow shaft.",
    "8. A device for drilling an anatomical element comprising: a drill bit comprising a coaxial hollow shaft in communication with at least one aperture disposed on a surface of the drill bit; at least one processor; and a memory storing instructions for execution by the at least one processor that, when executed, cause the at least one processor to: cause the drill bit to rotate, open a valve that releases pressurized fluid into the coaxial hollow shaft, and monitor a pressure of the pressurized fluid to detect release of the pressurized fluid through the at least one aperture.",
    "9. The device of claim 8, wherein the memory stores additional instructions for execution by the at least one processor that, when executed, further cause the at least one processor to: receive sensor data from a sensor configured to measure the pressure of the pressurized fluid, and identify a drop in the pressure of the pressurized fluid based on the sensor data.",
    "10. The device of claim 8, wherein the at least one aperture is coaxial with the coaxial hollow shaft.",
    "11. The device of claim 8, wherein the at least one aperture is a plurality of apertures and one or more apertures of the plurality of apertures is disposed at an angle to an axis of the coaxial hollow shaft.",
    "12. The device of claim 8, wherein the at least one aperture has a non-circular cross section.",
    "13. A system for drilling an anatomical element comprising: a drill bit configured to drill an anatomical element, the drill bit comprising a coaxial hollow shaft in communication with at least one aperture disposed on a surface of the drill bit; a fluid system in fluid communication with the coaxial hollow shaft, the fluid system configured to pressurize a fluid and to dispense the pressurized fluid into the coaxial hollow shaft; a motor operatively connected to the drill bit; a user interface for selectively operating the motor; at least one processor; and a memory storing instructions for execution by the at least one processor that, when executed, cause the at least one processor to: cause the motor to rotate the drill bit, cause the fluid system to pressurize the fluid and dispense the pressurized fluid into the coaxial hollow shaft, and monitor a pressure of the pressurized fluid to detect release of the pressurized fluid through the at least one aperture.",
    "14. The system of claim 13, wherein the at least one aperture is coaxial with the coaxial hollow shaft.",
    "15. The system of claim 13, wherein the at least one aperture is a plurality of apertures and one or more apertures of the plurality of apertures is disposed at an angle to an axis of the coaxial hollow shaft.",
    "16. The system of claim 13, wherein the fluid is at least one of water or saline.",
    "17. The system of claim 13, wherein the fluid system is configured to dispense the pressurized fluid into the coaxial hollow shaft after a predetermined period of time after activation of the drill bit, at a predetermined drilling depth, or after a predetermined drilling time.",
    "18. The system of claim 13, further comprising: a pressure sensor configured to monitor the pressure of the pressurized fluid, and wherein the motor is configured to stop upon detection of a pressure drop by the pressure sensor.",
    "19. The system of claim 18, wherein an alert is generated and communicated via the user interface upon detection of the pressure drop by the pressure sensor."
