Abstract

The invention relates to the technical field of medical instruments, and particularly provides a feedthrough assembly for implantable medical equipment and a manufacturing method of the feedthrough assembly. The feedthrough assembly comprises a feedthrough connector, a capacitor filter, a metal supporting piece and a conductive material, wherein the metal supporting piece is located on the outer side of the capacitor filter; the metal supporting piece comprises at least one of a titanium material and a nickel material; one end of the metal supporting piece is welded and fixed to a titanium flange, the other end of the metal supporting piece extends in the direction away from the titanium flange, and the inner wall of the metal supporting piece faces the outer wall of the capacitor filter;and the conductive material is filled in an outer welding seam gap between the inner wall of the metal supporting piece and the outer wall of the capacitor filter, so that the metal supporting piece and the capacitor filter are fixed and electrically connected. According to the embodiment of the invention, through the design of the metal supporting piece, the difficulty in connecting the capacitorfilter with the feedthrough connector is solved, and the connection between the capacitor filter and the feedthrough connector is simply and reliably realized.

Description

technical field [0001] The present disclosure relates to the technical field of implantable medical equipment, in particular to a feedthrough assembly for implantable medical equipment and a manufacturing method thereof. Background technique [0002] Feedthrough connectors are widely used in implantable medical devices, especially implantable medical devices with electrical stimulation functions. Feedthrough connectors are currently used in implantable medical devices such as cardiac pacemakers, deep brain stimulators, and spinal cord stimulators. [0003] Feedthrough filter is a commonly used device in electronic technology. It can effectively filter out stray interference signals in the line and improve the reliability of signal transmission. With the complexity of electronic systems and signal output methods of implantable medical devices, feedthrough connectors that meet the requirements of airtightness and biocompatibility and have strong filtering performance have bec...
