Subclavian vein puncture method for double-cavity pacemaker implantation surgery

Abstract

The invention relates to a subclavian vein puncture method for a double-cavity pacemaker implantation surgery. The subclavian vein puncture method comprises the following steps of: puncturing a subclavian vein by using a puncture needle, and pumping back return blood after puncture; he pulling out a needle cylinder, and enabling a double-helix guide wire to penetrate into the puncture needle fromthe tail end of the puncture needle; pulling out the puncture needle, enabling an expansion sheath to sleeve a first guide wire, and pushing forward the expansion sheath in the direction of the firstguide wire to expand skin, subcutaneous tissue and muscle under the clavicle; pulling out the expansion sheath, enabling an atrial tearing sheath to sleeve the first guide wire, pushing forward the atrial tearing sheath to the head end of the first guide wire, so that the double-helix guide wire is completely unfastened in the subclavian vein, and the first guide wire and a second guide wire are completely separated, and pulling out the first guide wire; enabling a ventricular tearing sheath to sleeve the second guide wire, pushing forward the ventricular tearing sheath to the head end of thesecond guide wire, and pulling out the second guide wire; enabling atrial / ventricular electrodes to be respectively implanted into the atrial / ventricular tearing sheaths; pulling and tearing the atrial / ventricular tearing sheaths; mounting a battery to connect the atrial electrode and the ventricular electrode; and placing the battery in a bag.

Description

technical field [0001] The invention relates to the technical field of dual-chamber pacemaker implantation, in particular to a subclavian vein puncture method for dual-chamber pacemaker implantation. Background technique [0002] In the implantation of a dual-chamber pacemaker, two electrodes need to be placed (one electrode is placed in the atrium of the human body, and the other electrode is placed in the ventricle of the human body). The existing method requires two punctures to place the two electrodes respectively , the defects caused are: 1. After the first puncture is put into the guide wire, the second one often fails to puncture the subclavian vein, resulting in a long operation time and increasing the pain of the patient; 2. The patient needs to puncture twice, increasing the The patient is in pain, the amount of anesthetic is large, the operation time is long, and the operation is cumbersome. Contents of the invention [0003] Aiming at the problems and deficie...
