Embodiment Construction
[0046] The present invention will be further described below in conjunction with accompanying drawing.
[0047] Such as figure 1 As shown, a tumor magnetically mediated hyperthermia device based on an implanted coil includes a signal generator, an internal coil 2 and an external coil 1 . The extracorporeal coil 1 is an open-loop single-turn circular coil (that is, one place is disconnected). The two disconnected terminals of the external coil 1 are respectively connected to the signal output terminal and the ground terminal of the signal generator. The internal body coil 2 is a closed-loop single-turn circular coil (that is, the internal body coils are connected end to end). The radii of external coil 1 and internal coil 2 are r 1 and r 2 , the wire radius used is r w1 and r w2 . The coil in the body adopts biometal material (titanium alloy is used in this embodiment). r 2 Equal to 1 / 5 of the diameter of the tumor to be implanted. r 2 with r w2 satisfy the equation...
