Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, and particularly relates to a novel uninterrupted rotation pacemaker intraoperative test line. BACKGROUND

[0002] An artificial heart pacemaker can emit regular electric pulses to keep the heart beating, and is widely used in the medical field. The pacemaker, the pacemaker electrode lead and the programmer constitute a pacing system, wherein the pacemaker and the pacemaker electrode lead are implanted in the human body through surgery. The SelectSecure 3830 pacemaker electrode lead of the Medtronic company is a solid electrode lead, which can be used for pacing at any part of the heart cavity with the help of a delivery catheter, and is currently mainly used for pacing in the His bundle and left bundle branch area. The electrode lead has an electrode end at one end for connecting the pacemaker, and a screw-in end at the other end for implanting into the patient's heart. The electrode end and the screw-in end are both provided with a cathode and an anode. Since the anode of the electrode end is a ring structure, it is also called an anode ring. The operator rotates the outer skin of the 3830 pacemaker electrode lead to drive the entire electrode lead to rotate, so as to implant the screw-in end of the 3830 pacemaker electrode lead into the patient's heart. During the operation, the operator needs to use a monitor and a pacemaker programmer to monitor the electrocardiogram in the cathode cavity of the screw-in end and the electrode impedance change under the pacing state at any time during the screwing-in process of the screw-in end, especially during the process of clockwise screwing the electrode from the right side of the interventricular septum into the left side. In the current technology, the cathode of the electrode end of the 3830 pacemaker electrode lead is fixed by a crocodile clip and connected to the monitor through a cathode test line, and the patient's skin is fixed by a crocodile clip and connected to the monitor and the pacemaker programmer through an anode test line. During the monitoring process, according to different situations, a crocodile clip can also be clamped on the anode ring, and connected to the monitor and the pacemaker programmer through an anode ring test line, so as to obtain more and more accurate data. When the operator rotates the outer skin of the 3830 pacemaker electrode lead, the end of the test line fixed by the crocodile clip cannot rotate synchronously, which causes the test line at this position to be wound and knotted, so that the electrocardiogram in the cathode cavity and the electrode impedance monitoring have to be interrupted, resulting in that the screwing-in stroke cannot be continuously monitored in real time. However, the change of the electrocardiogram itself is an important basis for guiding whether the screw-in end reaches the site, and the current method is mostly in the state of "screwing in-interrupting monitoring; monitoring-interrupting screwing in", or the crocodile clip is loosened after screwing in for a stroke, and then the wound and knotted part of the test line is untied, and then the crocodile clip is clamped again to monitor whether it is screwed to the position. Such repeated operations bring inconvenience to the operator, and the screw-in end often needs to be rotated out of the position due to untimely monitoring, which causes pain to the patient.

[0003] In view of the above problems, the application with publication number CN109529195A discloses a cathode inner rotation type pacemaker implantation test line, which comprises a test line, the test line comprises an anode ring test line, a cathode test line and a subcutaneous anode test line; the anode ring test line and the subcutaneous anode test line are fixedly connected with alligator clamps at both ends; the cathode test line is fixedly connected with an alligator clamp at one end and is fixedly connected with a rotatable cathode clamp at the other end. The cathode inner rotation type pacemaker implantation test line has the advantages of simple structure, convenient use, and the cathode test clamp can fix the cathode of the 3830 (SelectSecure 3830 of Medtronic company) pacemaker electrode lead electrode end and rotate together, so that the operator can monitor the electrode impedance change of the pacemaker electrode cathode end during the twisting process and the intracavity electrocardiogram shape change in the pacing state, or the intracavity electrocardiogram shape change in the non-pacing state.

[0004] However, the cathode inner rotation type pacemaker implantation test line still has the following problems in the process of use: 1. The cathode inner rotation type pacemaker implantation test line cannot guarantee the stability of signal transmission during rotation. SUMMARY
