Description

Magnetic field irradiation device {Device for Irradiating Magnetic Field}

The present invention relates to a magnetic field irradiation device, and more particularly, to a magnetic field irradiation device for inducing transport of magnetic particles injected into a user's spinal cord using a magnetic field.

In general, medical devices are driven wirelessly or wired to diagnose or treat lesions in organs such as blood vessels and digestive organs. Among them, small-sized medical devices inserted into the human body and used for diagnosis have difficulties in development because they are not suitable for having a battery or an actuator.

Recently, studies using magnetic fields are being conducted to control small medical devices inserted into the human body. In order to be controlled using a magnetic field, the medical device is partially or entirely composed of a magnetic material without a battery or a separate actuator. If the battery or actuator is replaced with a magnetic material, the medical device can be designed in a compact size. Medical devices with a minimized size enable minimally invasive procedures. This has the advantage of reducing the patient's pain and recovery period because the incision site is minimized during surgery.

A medical device having a magnetic material may be controlled by an external magnetic field generating device. The magnetic field generator used is a permanent magnet and an electromagnet. The permanent magnet can be driven by controlling the distance between the medical device and the permanent magnet and the direction of the magnetic field. However, in this case, there is a problem in that there is a limit to the movement and control speed of the medical device.

A medical device driven by an electromagnet can be controlled with a magnetic field generated by applying a current to a coil disposed outside. At this time, if the intensity and direction of the current applied to each coil are controlled, the desired driving of the medical device can be realized. The method using the electromagnet is easier to control than the method using the permanent magnet, and the movement of the medical device can be rapidly controlled according to the characteristics of the coil.

However, as the medical device is further separated from the electromagnetic driving device, the magnetic field acting on the medical device rapidly decreases. In this case, in order to control the medical device, the electromagnetic driving device has a problem in that a large amount of current must be applied to the coil according to the separation distance. More specifically, in the conventional electromagnetic driving device, a coil is fixedly disposed to form a magnetic field on a table on which an examinee lies. Therefore, when diagnosing a subject, the separation distance between the coil and the medical device changes according to the subject's body shape and diagnosis site. It is inefficient in terms of control precision and power to control the amount of current applied to the coil in consideration of the strength of the magnetic field that varies with distance.
