Magnetic Capsule Endoscope Needle Orientation Control

A magnetic field is introduced as an intermediary between the external controller and the capsule endoscope. The magnetic field acts as a mediator to transmit orientation control commands to the magnetic responding unit within the capsule, enabling precise positioning and orientation of the needle without direct mechanical manipulation. This resolves the contradiction by providing remote, precise control capability while maintaining the minimally invasive nature of the capsule.

The patent replaces traditional mechanical positioning and orientation mechanisms with a magnetic field-based control system. Instead of using complex mechanical actuators or manual manipulation to position the needle, a magnetic field is used to actuate the magnetic responding unit, which in turn controls the needle's orientation. This substitution enables more precise and flexible control while reducing mechanical complexity.

The magnetic field serves as an intermediary control mechanism that simplifies the overall system architecture. Rather than implementing complex mechanical control mechanisms within the capsule for needle orientation, the magnetic field externally controls a magnetic responding unit that actuates the needle. This approach improves injection accuracy while avoiding the addition of complex internal control mechanisms.

Complex mechanical control mechanisms for needle orientation are replaced with a magnetic field-based actuation system. The magnetic responding unit, when exposed to an external magnetic field, changes its magnetization direction to orient the needle toward the target layer. This substitution reduces device complexity by eliminating the need for complex mechanical actuators, gears, or linkages within the capsule while achieving precise needle control.

Complex mechanical positioning mechanisms are replaced with a magnetic responding unit that responds to external magnetic fields. The magnetic responding unit can be actuated by applying magnetic fields in specific directions, enabling precise control of the capsule and needle orientation without requiring complex mechanical actuators, sensors, or control systems within the capsule. This substitution improves position precision while keeping the added complexity relatively low.

The magnetic responding unit serves multiple functions: it controls the orientation of the capsule body, positions the needle, and enables alignment with target layers. By using a single magnetic responding unit for multiple control tasks, the patent improves position precision without proportionally increasing device complexity. The same magnetic field mechanism that orients the capsule also positions the needle and aligns it with the target.
