Abstract
The invention discloses an implantable medical device with a structure for preventing screw-out of screws. The device includes a shell, a battery and a circuit board both arranged in the shell, and a connecting head hermetically connected with the shell. The connecting head includes a plurality of connecting blocks, a wireless communication antenna and a sealing filler. The connecting blocks are radially provided with screw holes which are in communication with connecting holes. Screws for pressing connection of conductive rings on line traps are arranged in the screw holes. A screw thread on an end part, close to a corresponding water seal part, of each screw, is filled with the filler covered by threads. When a doctor reversely operates, the screws only apply a downward push-out force to the water seal parts and do not apply any upward spiral feeding force. The lengths of joint cuttings arranged in the water seal parts are smaller than the outer diameters of the corresponding screws so that even if the screws are completely screwed out of the connecting blocks, the screws do not pass through the joint cuttings in the water seal parts. Therefore, the probability that the water seal parts are damaged in function because of misoperation of the doctor is reduced. The invention also discloses a medical system including the implantable medical device.
