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 an elastic electric connector of an active implantable medical device and a connecting structure of the elastic electric connector. The elastic electric connector comprises: a first connecting section which is positioned at one end, and is a straight section and is suitable for being electrically connected with a hard circuit board in the active implantable medical device; and an elastic deformation section which is positioned at the other end and is provided with an arc structure and a clamping structure which are formed by bending, and the arc structure is suitable forbeing electrically connected with a coil in the active implantable medical device. According to the elastic connector, the first connecting section and the hard circuit board in the active implantable medical device can be used for rigidly connecting the hard circuit board and the elastic connector; and after the rigid connection is welded, compared with the traditional surface-mounted connectionof flexible connection, the elastic electric connector has the advantages that the connector is more convenient in disassembly and is not easy to damage after being disassembled, so that the active implantable medical device can be disassembled and assembled for many times, and the active implantable medical device is convenient to maintain.

Description

technical field [0001] The invention relates to the technical field of implantable medical devices, in particular to an elastic electrical connector of an active implantable medical device and its connection 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 m...
