Abstract
Provided is a magnetic actuation system controlling a magnetic microrobot, a magnetic actuation catheter, or a guide wire by using a magnetic field, and more particularly, a magnetic actuation system compatible with a C-arm that is applied to the C-arm, which is a mobile X-ray fluoroscopy device, in order to enable control of the microrobot or a catheter treatment in a human body by using the C-arm.
Claims20
A magnetic actuation system compatible with a C-arm that is positioned on the C-arm including a C-shaped arc body, a receiver positioned at one end of the arc body, a transmitter positioned at the other end of the arc body, and a treatment space positioned between the receiver and the transmitter, the system comprising:
- an electromagnet unit including a combination of one or more electromagnets and positioned between the transmitter and treatment space of the C-arm;
- and
- a power supply unit supplying a current to the electromagnet unit,
- wherein the electromagnet unit is disposed below the treatment space by generating a magnetic field or a magnetic force through the current supplied from the power supply unit, and
- actuates a magnetic robot, a magnetic actuation catheter, or a guide wire, including a magnetic body wirelessly,
- wherein the electromagnet unit is fixed to and supported by an external supporter positioned separately from the C-arm, and
- wherein each electromagnet of the electromagnet unit is inclined at an inclination angle with respect to a reference line, which is perpendicular to a ground, such that the inclination angle is same as an angle between the reference line and a traveling direction of an X-ray transmitted from the transmitter.
A magnetic actuation system compatible with a C-arm that is positioned on the C-arm including a C-shaped arc body, a receiver positioned at one end of the arc body, a transmitter positioned at the other end of the arc body, and a treatment space positioned between the receiver and the transmitter, the system comprising:
- an electromagnet unit including a combination of one or more electromagnets and positioned between the transmitter and treatment space of the C-arm;
- a power supply unit supplying a current to the electromagnet unit;
- and
- an auxiliary coil having a hollow portion in a center thereof and fixed to the receiver or transmitter of the C-arm and receiving the current from the power supply unit,
- wherein the electromagnet unit is disposed below the treatment space by generating a magnetic field or a magnetic force through the current supplied from the power supply unit, and actuates a magnetic robot, a magnetic actuation catheter, or a guide wire, including a magnetic body wirelessly,
- wherein the auxiliary coil is disposed above the treatment space by generating the magnetic field or the magnetic force through the current supplied from the power supply unit, and actuates the magnetic robot, the magnetic actuation catheter, or the guide wire, including the magnetic body wirelessly, and
- wherein an X-ray transmitted from transmitter passes through the hollow portion in the center of the auxiliary coil.
