Example one

An implantable pacemaker as shown in fig. 1-9, the pacemaker 1 includes a pacemaker body 3 and an electrode connecting terminal 2; the pacemaker body 3 and the electrode connecting terminal 2 are bonded as a whole by using a biocompatible epoxy resin or silicone rubber. The electrode connecting end 2 is connected with an electrode lead 18 for sensing electrocardiosignals of a human body.

Specifically, the material of the electrode connection end 2 is a biocompatible polymer material, such as one or more of epoxy resin, thermoplastic polyurethane elastomer rubber (TPU), polyether ether ketone (PEEK), Polysulfone (PSF), and the like. The pacemaker body 3 has a metal shell made of biocompatible titanium metal, typically pure titanium or titanium alloy. The pacemaker main body 3 shell is formed by closing two half shells, and is melted at a joint position through laser firing to form an airtight sealed metal shell.

PCB circuit module 15 is used to deliver cardiac pacing pulse signals and sense and process signals generated by the myocardium. The feed-through assemblies 8-1-8-2 are used for transmitting myocardial electrical signals inside and outside the pacemaker main body 3, and optionally, the feed-through assemblies 8-1-8-2 with filtering functions can be adopted, so that interference signals transmitted from the outside of the pacemaker main body 3 to the inside of the pacemaker main body 3 can be filtered, and the interference signals are eliminated for the PCB circuit module 15. The program control coil 17 is mainly used for wireless communication between the program control instrument 20 and the pacemaker 1. By means of the programming coil 17, the programmer 20 can set the functional parameters of the pacemaker 1 appropriately and read the historical heart rate data of the patient.
