Description

Fixing device of postoperative pacemaker

Technical Field

The utility model belongs to the technical field of medical equipment, and particularly relates to a fixing device of a post-operation pacemaker.

Background

Pacemaker implantation is the primary method of treating irreversible cardiac pacing and conduction dysfunctional disease due to a variety of causes. It is often used for patients with symptomatic bradycardia. The artificial implanted cardiac pacemaker has pulse current in specific frequency, and through lead and electrode, stimulates heart to replace cardiac pacemaker to drive cardiac pulse. The management of the postoperative capsular bag of the pacemaker is vital, and capsular bag hemorrhage and hematoma are common complications after the pacemaker operation, and can cause capsular bag infection and seriously affect the operation effect if the treatment is improper. In order to reduce or prevent the occurrence of bleeding and hematoma, a local sandbag compression method is generally adopted clinically, namely, a sandbag with certain mass is placed at the pacemaker implantation position, and the pacemaker implantation position is stabilized by pressing hands of a patient or directly inserting the pacemaker implantation position into clothes, but long-time hand pressing obviously greatly affects postoperative rest of the patient. If the sandbag is directly plugged into clothes, the sandbag slips due to the fact that no effective fixing part exists, and meanwhile, the sandbag is fixed by the vest type method, so that the sandbag is complex and inconvenient to use clinically. To this end, we propose a fixation device for a post-operative pacemaker.
