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 t...

Abstract

The invention provides a traction device for pulling out a temporary cardiac pacemaker wire. The traction device is suitable for being used when a pacemaker wire is pulled out after a patient implanted with a temporary pacemaker after a cardiac surgical operation. The installation of a temporary epicardium pacemaker is widely applied clinically, for example, slow arrhythmia occurs after surgery or the heart rate needs to be increased to improve the hemodynamic effect, and implantation of a temporary endocardium pacemaker fails. The pacemaker wire needs to be pulled out within 2-12 days when the temporary epicardium pacemaker is implanted, and if the pacemaker wire is not pulled out, infection is easily caused, or even a debridement operation is needed. Due to various reasons, the condition that the pacemaker wire cannot be pulled out sometimes still happens. The traction device can effectively solve the problem that the pacemaker wire cannot be pulled out in some operations, and can be used for continuously and slowly pulling the wire; the wire can be slowly pulled out by utilizing puling force and pulling force of the heart; and complications possibly endangering the life of a patient, such as cardiac rupture and pericardium tamponade, which possibly occur when the wire is pulled forcibly, are effectively solved.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a pulling device for pulling out a lead of a temporary cardiac pacemaker. Background technique [0002] A cardiac pacemaker is an electronic therapy device implanted in the body. It consists of a pulse generator and a metal wire connected to it. The pulse generator sends out an electric pulse powered by a battery. The touched myocardium makes the heart excited and contracted, so as to achieve the purpose of treating cardiac dysfunction caused by certain arrhythmias. [0003] 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. [0004] At present, the epicardial temporary pacemaker lead wire used in open-sight cardiac surgery is made of metal, which is a braided guide wire ...
