Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a cardiac pacemaker fixing device for clinical use in cardiac surgery. Background Art

[0002] A pacemaker is an electronic therapeutic device implanted in the body. It emits electrical pulses powered by a battery through a pulse generator. Through the conduction of wire electrodes, it stimulates the myocardium that the electrodes contact, causing the heart to become excited and contracted, thereby achieving the purpose of treating heart dysfunction caused by certain arrhythmias.

[0003] When using pacemakers for auxiliary treatment of patients, the fixation of the pacemaker is a major problem that needs to be solved urgently during clinical nursing and treatment. The pacemaker is not firmly fixed during use and is often dislocated or falls off, which may cause serious harm to the patient in severe cases. Therefore, we have launched a new pacemaker fixation device for clinical use in cardiac surgery. Utility Model Content
