Abstract
A method of using a medical tool comprising a cranial access drill includes placing a guide-hub against a cranial drilling surface, guiding a drill bit into the guide-hub along an axial direction of the guide-hub, drilling the cranial drilling surface in the axial direction with the drill bit using a motor, detecting, using a controller, an electrical parametric change at the drill bit that corresponds to puncturing the cranial drilling surface, and deactivating, using the controller, the motor in response to detecting the electrical parametric change.
Claims20
A method of using a medical tool comprising a cranial access drill, the method comprising:
- placing a guide-hub against a cranial drilling surface, the guide-hub comprising an axial direction;
- guiding a drill bit into the guide-hub along the axial direction;
- drilling the cranial drilling surface in the axial direction with the drill bit using a motor;
- detecting, using a controller, an electrical parametric change at the motor that corresponds to puncturing the cranial drilling surface, the electrical parametric change being a voltage change at the motor;
- and
- deactivating, using the controller, the motor in response to detecting the electrical parametric change.
A method of using a drilling system, the method comprising:
- placing a guide-hub on a drilling surface, the guide-hub comprising an axial direction;
- guiding a drilling insert into the guide-hub along the axial direction, wherein the drilling insert comprises a drill bit and a harness;
- drilling the drilling surface with the drill bit, wherein the axial direction of the guide-hub is parallel to a surface normal of the drilling surface during the drilling;
- detecting, using the harness, when the drill bit punctures the drilling surface;
- and
- automatically stopping the drilling in response to detecting that the drill bit has punctured the drilling surface,
- wherein the drilling surface is a cranial drilling surface,
- wherein the drilling comprises drilling the cranial drilling surface by rotating the drilling insert within the guide-hub along with the drill bit, and
- wherein the detecting comprises detecting, by the harness, when the drill bit punctures the cranial drilling surface to prevent further plunge using an electrical parametric change that corresponds to puncturing the cranial drilling surface or using an engaged friction lock of the harness that disengages automatically when the drill bit punctures the cranial drilling surface.
A method of using a cranial access drill, the method comprising:
- drilling a cranial surface with a drill bit of the cranial access drill using a motor causing the drill bit to spin;
- puncturing the cranial surface with the drill bit;
- detecting, using a controller, an electrical parametric change in electrical properties of an electrical circuit resulting from a torque change at the motor that corresponds to puncturing the cranial surface;
- and
- deactivating, using the controller, the motor to stop the drill bit from spinning in response to detecting the electrical parametric change.
