A pulling device for removing the lead of a temporary cardiac pacemaker

Abstract

The invention is suitable for use when the pacemaker leads are pulled out after surgery for patients implanted with a temporary pacemaker after cardiac surgery. The installation of temporary epicardial pacemakers is widely used clinically, such as bradyarrhythmia after surgery or the need to increase the heart rate to improve hemodynamic effects, failure of endocardial temporary pacemaker implantation, etc. It is necessary to remove the pacemaker lead within 2 to 12 days after the implantation of a temporary epicardial pacemaker. If the lead is not removed, it may cause infection, and even debridement surgery is required. Due to various reasons, the pacemaker lead cannot be removed temporarily. It still happens from time to time. The present invention can effectively solve some problems that the lead wires of the pacemaker cannot be pulled out during the operation. Using the present invention, the lead wires can be continuously and slowly pulled, and the lead wires can be pulled out slowly by using the beating force and pulling force of the heart, effectively solving the problem of The possible life-threatening complications such as cardiac rupture and cardiac tamponade that may occur when the wire is pulled hard are avoided.

Description

A pulling device for pulling out the lead of a temporary cardiac pacemaker technical field The invention belongs to the field of medical equipment, be specifically related to a kind of pulling device for pulling out the temporary pacemaker wire of the heart set. Background technique A pacemaker is an implanted electronic therapy device consisting of a pulse generator and a gold It is composed of wires, which emit electrical pulses powered by batteries through a pulse generator, and stimulate electrical impulses through the conduction of wire electrodes. The heart muscle that is touched by the pole makes the heart excited and contracted, so as to achieve the treatment of cardiac dysfunction caused by certain arrhythmias obstructing purpose. The clinical application of installing epicardial temporary pacemaker is very extensive, such as the occurrence of slow heart rhythm after surgery. Abnormal or need to increase heart rate to improve hemodynamic effect, failure ...

AI Technical Summary

Problems solved by technology

However, due to various reasons, the pacemaker wire cannot be pulled out from time to time. At this time, another thoracotomy is often required, which not only increases the pain and burden of the patient, but also causes a hidden danger of doctor-patient disputes.

It can be seen that the most critical step after the implantation of a temporary epicardial pacemaker is to pull out the lead wire of the temporary epicardial pacemaker. Adhesion or tight suture between the wire and the epicardium is difficult to pull out. At this time, if the wire is pulled out forcibly, it is very likely to cause heart rupture, cardiac tamponade, and even life-threatening death of the patient
