Abstract
Certain embodiments include a system and method for braking in a patient positioning system. The system includes a patient positioning surface for supporting a patient, a first brake for affecting motion of the patient positioning surface, and a second brake for affecting motion of the patient positioning surface. In an embodiment, the first brake is a power-off brake that is active when power is removed from the brake. The second brake is a power-on brake that is active when power is applied to the brake. Power may be applied and/or removed from the first and second brakes to affect the motion of the patient positioning surface.
Claims5
A braking system for a patient positioning surface used in a medical procedure, said system including:
- a first brake configured to affect movement of said patient surface when power is supplied to said first brake;
- and
- a second brake configured to affect movement of said patient surface when no power is supplied to said second brake, wherein said first brake is mounted on a first pinion and said second brake is mounted on a second pinion, said first and second pinions each configured to mesh with a single bull gear.
A rotational axis braking system for a patient positioning surface used in a medical procedure, said system comprising:
- a patient positioning surface for supporting a patient;
- a first brake mounted on a first pinion, said first brake configured to affect motion of said patient positioning surface when power is supplied to said first brake;
- a second brake mounted on a second pinion, said second brake configured to affect motion of said patient positioning surface when no power is supplied to said second brake;
- and
- a bull gear configured to mesh with said first pinion and said second pinion, said first and second brakes each configured to affect motion of said patient positioning surface through torque multiplication.
