Problems solved by technology

[0004] No matter which connection process is used above, it is inevitable to use the flexible connection board, and since the flexible connection board is welded and connected with the coil or the hard circuit board, and then glued and fixed, the flexible connection board is not easy to disassemble. Unqualified disassembly is likely to cause damage to the entire device
In addition, after the flexible connecting board is welded, in order to ensure the welding quality, the requirements for storage time and storage conditions are relatively high

Abstract

The invention provides a rigid connection piece of an active implantable medical device and a connection structure thereof. The rigid connection piece comprises a first connecting section, a second connecting section and a bent section, wherein the first connecting section is positioned on one end and is a straight section suitable to be electrically connected to a hard circuit board in the activeimplantable medical device; the second connecting section is positioned at the other end opposite to the first connecting section, and the second connecting section is a straight section suitable tobe electrically connected to a wire coil in the active implantable medical device; the bent section is positioned between the first connecting section and the second connecting section and is a bent structure; the rigid connection piece of the present invention is used to electrically connect the hard circuit board and the wire coil in the active implantable medical device, a flexible connection piece is replaced, and the rigid connection piece can be disassembled easily; in addition, a middle section of the rigid connection piece is the bent section which can be used for buffering welding spot stress at both ends and improving firmness and stability of electrical connection.

Description

technical field [0001] The invention relates to the technical field of implantable medical devices, in particular to a rigid connector of an active implantable medical device and its connecting structure. Background technique [0002] Human body active implantable medical device (Active Implantable Medical Device, AIMD) is a medical device installed inside the user's body. This device has batteries, hard circuit boards (with sensors, chips and other components) inside, and AIMD relies on The corresponding therapy can be realized through the set programs and operating parameters, and these operating parameters can adopt different settings according to the user's disease conditions. Because of the different causes and conditions of users, the active implantable medical devices installed in different users generally have different operating states. These operating states are reflected in the battery voltage, running time, power, Current magnitude, frequency and many other aspe...
