Pacemaker implantation testing line with negative pole and positive pole capable of rotating at the same time

Abstract

The invention provides a pacemaker implantation testing line with a negative pole and a positive pole capable of rotating at the same time. The testing line comprises testing line bodies. The testingline bodies include the positive electrode ring testing line, the cathode testing line and the subcutaneous positive electrode testing line; the two ends of the subcutaneous positive electrode testingline are each fixedly connected with a crocodile clip; one end of the positive electrode test line is fixedly connected with the crocodile clip, and the other end of the positive electrode test lineis fixedly connected with a negative and positive rotating clip; the crocodile clip is fixedly connected to one end of the positive ring testing line, and the other end is communicated and connected to the rear portion of the negative and positive rotating clip. The pacemaker implantation testing line with the negative pole and the positive pole capable of rotating at the same time is simple in structure and convenient to use, the testing clip can fix negative and positive rings of 3830 (Medtronic company Select Secure 3830) pacemaking electrode wire electrode ends, and can rotate along with the rings, and therefore twisting and knotting are avoided.

Description

technical field [0001] The invention relates to a medical device, in particular to a pacemaker implant test line whose cathode and anode can rotate simultaneously. Background technique [0002] Artificial heart pacers are widely used in the medical field because they can send out regular electrical pulses to keep the heart beating. Pacemaker, pacing electrode leads and program controller constitute the pacing system, in which the pacemaker and pacing electrode leads are surgically implanted into the human body. [0003] Medtronic's SelectSecure 3830 pacing lead wire is a solid-core lead wire that can be used for pacing at any part of the heart cavity with the help of a delivery catheter. Currently, it is mainly used for pacing in the His bundle and left bundle branch region. One end of the electrode wire is an electrode end for connecting a pacemaker, and the other end is a screw-in end for implanting into a patient's heart. Both the electrode end and the screw-in end are p...

Problems solved by technology

In the current technology, the cathode of the electrode end of the 3830 pacing electrode wire is fixed by the alligator clip and connected to the monitor through the cathode test line, and the patient's skin is used as the anode, which is fixed by the alligator clip and connected to the monitor and the pacing program control through the anode test line During the monitoring process, according to different situations, you can also choose to clip the crocodile clip on the anode ring, and connect it to the monitor and pacing program controller through the anode ring test line to obtain more and more accurate data; When the outer skin of the 3830 pacing electrode lead is turned, the end of the test line fixed by the alligator clip cannot rotate synchronously, causing the test line at this position to be entangled and knotted, so the monitoring of the electrocardiography and electrode impedance in the cathode cavity has to be interrupted, resulting in the inability to screw in the stroke. Real-time and continuous monitoring of changes in ECG and electrode impedance, but the ECG change itself is an important basis for guiding whether the screw-in end is screwed in to the site

Most of the current practices are in the state of "screw-in-interrupt monitoring; monitor-interrupt screw-in", or loosen the alligator clip after screwing in for a certain stroke, untie the winding and knotted part of the test line, and then clip the alligator clip to Monitoring whether it is screwed in place, repeated operations like this will bring inconvenience to the operator, and often the screw-in end is screwed in too much due to untimely monitoring and needs to be turned back, which brings pain to the patient
