Abstract
The invention provides a sealing structure for an implantable-type medical instrument, and the structure comprises a screw, wherein the screw is provided with an external thread cooperating with a threaded hole on a connection block, and a heat part extending outwards in a radial direction; and an insulating seal ring which sleeves the screw and is disposed between the connection block and the screw. When the screw is fastened, the insulating seal ring is extruded and compressed in an axial direction. The connection block enables an electrode wire extending into a connection hole to be fixed, and enables the screw to have an overall downward pull force, so as to extrude the insulating seal ring, and enable the insulating seal ring to be compressed in the axial direction, thereby enabling the insulating seal ring to expand in the radial direction, enabling the insulating seal ring to completely contact with the outer wall of the screw and the inner wall of a seal hole, applying action forces on the outer wall of the screw and the inner wall of the seal hole, improving the sealing performance, and preventing water, body fluid or foreign matters from entering the implantable-type medical instrument. In addition, the invention also provides a pulse generator with the sealing structure for the implantable-type medical instrument.
