This technology is a system that delivers power wirelessly to a microrobot equipped with a wireless power transmission module at the tip of a catheter, which can be detached at a specific point within the body. It includes a magnetic resonance-based wireless power transfer mechanism between the catheter and the robot, as well as an alignment and reconnection mechanism using ultrasonic sensors.
Existing microrobots require external magnetic fields to be induced deep into the body to supply power, which leads to significant energy loss and difficulties in securing sufficient space for procedures due to the need for large coil systems.
This technology utilizes a structure where a catheter transports the robot to a specific location, and after the robot is detached, the catheter's power transmission unit (helical/planar coil) and the robot's power supply unit exchange power via magnetic resonance. The reconnection and alignment of the catheter and robot are controlled through a positioning means (ultrasonic sensor). Applicable to surgical robots, interventional systems, and medical automation, it minimizes power supply efficiency degradation and enables stable data transmission, thereby enhancing the overall efficiency of power and data delivery.
This invention was developed with support from the Ministry of Trade, Industry and Energy for the development of a microrobotic medical system for the treatment of chronic total occlusion in myocardial infarction.
