Problems solved by technology

[0003] At present, the transvascular tear-off sheaths used in cardiology departments on the market are all single-channel. After the tear-off sheath enters the blood vessel along the guide wire, only one electrode can be implanted at a time, and the other electrode often needs to be re-inserted. After the puncture is successful, the tear sheath is placed, and multiple punctures will increase complications such as pneumothorax, hemothorax, puncture to the subclavian artery, and damage to the axillary nerve; this will reduce the efficiency of the operation, delay the operation time, and increase the incidence of complications rate; if a tear-away sheath with two channels can be designed, then two electrodes can be implanted into the heart through blood vessels at the same time, which can save operation time, reduce surgical complications, and complete the implantation of pacemaker electrodes. into work

Abstract

The invention discloses a double-channel tearing sheath for cardiac pacemaker electrode implantation. The double-channel tearing sheath is characterized by comprising a tearing sheath tube, a first cavity channel, a second cavity channel, a first cavity channel extension tube, a second cavity channel extension tube, a first cavity channel head seat, an expansion tube, an expansion tube head seat,a soft silica gel filling inner core, a flushing tube, a three-way valve and a one-way valve core plug, The tearing sheath is provided with two inner cavities and two channels at the same time, and two electrodes can be implanted at the same time, so that at least half of operation time can be saved, and implantation work of cardiac pacemaker electrodes is completed.

Description

technical field [0001] The invention belongs to the field of interventional medical auxiliary equipment, in particular to a double-channel tear-off sheath for cardiac pacemaker electrode implantation. Background technique [0002] Cardiac pacemaker is an electronic therapy device implanted in the body. It sends out electric pulses powered by batteries through the pulse generator, and stimulates the myocardium touched by the electrodes through the conduction of the wire electrodes, so as to excite and contract the heart, so as to achieve treatment. The purpose of cardiac dysfunction caused by certain arrhythmias; the most critical step in the implantation of cardiac pacemaker is the implantation of cardiac pacemaker electrodes. The two electrodes need to be pulled from the axillary vein or subclavian Intravenous delivery into the atria and ventricles; [0003] At present, the transvascular tear-off sheaths used in cardiology departments on the market are all single-channel. ...
