Problems solved by technology

However, there are still many defects in the miniature leadless pacemaker, including: it is fixed in the range of the ventricle, cannot pace the atrium, and the non-physiological pacing that easily leads to atrioventricular desynchronization increases; the success rate of removal and recovery is low; the fixation is not firm and causes Easy dislocation and other problems

Embodiment Construction

[0035] The core idea of ​​the present invention is to provide a cardiac pacing system and a pacemaker fixing device, wherein the pacemaker fixing device includes an annular bracket and at least one retractable portion, and the retractable portion includes a connecting portion and several circumferential To the storage and storage parts arranged, the first ends of all the storage and storage parts are collected and connected to the connecting part, and the connecting part is used for detachable connection with an external mechanism, and the second ends of all the storage and storage parts The end is connected to the end of the ring bracket, and one end of the retractable part is arranged outside the end along the axial direction of the ring bracket; the retractable part is used to cooperate with an external mechanism , shrink and fold under the pull of the external mechanism, and drive the ring-shaped support to shrink and fold.

[0036] Here, the leadless pacemaker is fixed in...

Abstract

The invention relates to a cardiac pacing system and a pacemaker fixing device. The pacemaker fixing device comprises an annular support and at least one contraction and release part. The annular support is used for mounting a lead-free pacemaker. The lead-free pacemaker can be conveniently and reliably fixed at a preset position in a body and prevented from dislocation. The device can be reliablyconnected with an external mechanism through the connecting part of the contraction and release part, therefore, the cardiac pacing system is convenient to recover and remove. The success rate of dismounting and recycling operations of the cardiac pacing system is improved. In an implantation process, the operation of the contraction and release part can be realized through the external mechanism, and the adjustment of the pacing position of the lead-free pacemaker is completed. An operator can conveniently find the optimal pacing position, so that the pacing effect of the lead-free pacemakeris improved. In addition, the lead-free pacemaker can be fixed in an atrium range to carry out pacing on atrium, and non-physiological pacing of atrioventricular desynchrony is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a cardiac pacing system and a pacemaker fixing device. Background technique [0002] Cardiac pacemaker is an electronic therapeutic device implanted in the body. It sends out electrical pulses through the pulse generator, conducts through the wire electrodes, and then stimulates the myocardium in contact with the electrodes, causing the heart to excite and contract, so as to achieve the treatment of certain heart rhythm problems. The purpose of cardiac dysfunction caused by abnormalities. However, for cardiac pacemakers with lead wires, the incidence rate of lead-related complications is high, which adversely affects the life and health of patients. However, the leadless pacemaker integrates the battery, loop and pacing electrode into a "pocket capsule" that can be implanted in the heart cavity. It only needs to be implanted by percutaneous puncture catheter technology. ...
