This utility model relates to the field of medical device technology, specifically to a coil assembly and a medical device. The coil assembly includes at least one insulating plate and a coil attached to the insulating plate with adhesive. Each insulating plate has multiple through holes and multiple serpentine holes, which are staggered. The serpentine holes are arranged radially from the center of the area where the coil is located on the insulating plate. This application combines multiple through holes with multiple serpentine holes, and the serpentine holes are arranged radially from the center of the area where the coil is located on the insulating plate. The serpentine holes, through their meandering path, increase the space for adhesive within the limited space of the insulating plate, providing sufficient adhesive capacity. Simultaneously, they can disperse stress, avoiding significant stress concentration caused by the presence of holes, and have minimal impact on the overall hardness and structural strength of the insulating plate, thus ensuring the mechanical properties of the coil assembly.
