Description

Left auricle plugging system capable of wirelessly supplying energy and wirelessly monitoring electrocardio

Technical Field

The utility model relates to the technical field of left auricle plugging instruments, in particular to a left auricle plugging system capable of wirelessly supplying energy and wirelessly monitoring electrocardio.

Background

Atrial fibrillation (atrial fibrillation) is one of the most clinically common arrhythmias, and in the last decades studies have demonstrated a close link between atrial fibrillation and stroke, systemic embolism, which is more closely linked with age. There have been a number of study report analyses that indicate that 90% of non-valvular atrial fibrillation patients have a stroke or systemic embolism related thrombus derived from the left atrial appendage; whereas in valve heart patients, about 40% of the patients' thrombi occur in the left atrial body and about 60% of the patients find thrombi in the left atrial appendage. The close correlation of left auricle thrombus and cerebral apoplexy and other thromboembolic events and the specific pathophysiological correlation thereof lay a foundation for the local positioning treatment of left auricle occlusion (LAAO). Surgical ligation of the left atrial appendage may reduce stroke events in patients with atrial fibrillation, and thus simultaneous removal of the left atrial appendage while performing an valvulotomy in patients with rheumatic valvular disease, particularly mitral stenosis, may reduce stroke by 50%. However, the possible complications of the operation include left atrial tear, local hemorrhage, postoperative pericarditis, suture opening, postoperative fever, suture opening thrombus, thromboembolism, etc. With the development of interventional devices, a treatment method which is less in wound, simple to operate and short in time consumption and is developed in recent years is percutaneous left auricle plugging, and currently, the main left auricle plugging in the world is percutaneous left auricle plugging; the special occluder is adopted to occlude the left auricle, thereby achieving the purpose of preventing cerebral apoplexy and other thromboembolic events caused by atrial fibrillation.

However, at present, the simple left auricle occlusion operation still needs to monitor the electrocardio of a patient, review the electrocardiogram, evaluate the arrhythmia attack conditions and characteristics such as atrial fibrillation after the occlusion device operation, and formulate a treatment scheme, a drug type and a dosage, so that electrocardiographic monitoring equipment is additionally worn after the operation.

Atrial fibrillation ablation is an effective means for controlling the rhythm of patients suffering from atrial fibrillation, and has been recommended by guidelines at home and abroad, but postoperative atrial fibrillation and other recurrence of atrial arrhythmia are always hot spots and problems of study in the academic world. Generally, the electrocardiogram and Holter have limited recording time, and can not accurately judge whether atrial fibrillation recurs or not, and whether other arrhythmia exists or not, so that an implantable long-term recording device is also required. In addition, the risk of thromboembolic events following atrial fibrillation ablation surgery is still determined by the stroke risk score, i.e., the CHA2DS 2-vacc score. Patients who are contraindicated for anticoagulants, cannot be used for a long period of time, or still have thromboembolic events when anticoagulants are administered are prescribed, a combination of atrial fibrillation ablation and left atrial appendage occlusion can be performed. This is also one of the important strategies for current management of atrial fibrillation.

Therefore, for patients with atrial fibrillation using atrial fibrillation ablation and left atrial appendage occlusion combined operation therapy, in order to well realize postoperative prevention and postoperative long-term monitoring, an implanted occluder is usually needed to be used for long-term recording, monitoring and management, however, at present, the implanted device must be provided with a power supply from the outside to realize wireless energy supply. Therefore, the application of the wireless power transmission technology to the field of medical instruments is a great difficulty in the current research.

In 2003, the japanese RF company developed an implantable endoscopic bio-telemetry system using this technology, and corresponding physical products were sequentially introduced in israel, korea, and europe. In 2005, masaya Watada in japan and y.um in korea proposed the concept of wireless power transmission to artificial hearts.

In 2008, the university of pisburg in united states applied wireless power transmission technology to in vivo implanted devices and conducted experimental studies in air, human head models, and pig living bodies. In 2013, the university of hong Kong city proposes a novel receiver structure aiming at the problem that weak flux linkage caused by coil imbalance in the application of retina prosthesis will seriously affect power efficiency.

In 2017, the scientific staff of the Ma province academy of engineering put forward a new technology of midfield coupling on the basis of the developed cochlear implant which is wirelessly charged by an external source, compared with near field coupling, the working frequency and the coupling efficiency are greatly improved, and the electric power is successfully transmitted to three receivers positioned in the esophagus, the stomach and the colon of a pig by using a transmitter positioned outside the pig body through experiments.

Furthermore, university of malaysia proposes an optimized inductively coupled WPT system for robotic capsule endoscopes. Indian pu NBN Sinhgad proposes a wearable pacemaker wireless power supply system based on magnetic resonance coupling. A wireless power transmission system for an implantable medical device with automatic power adjustment is proposed by the university of Qinghua.

Although the above research has made some breakthroughs, some key technologies are still to be further researched and explored, for example, most of the built-in batteries of the implanted monitoring devices in the above technologies are wireless power supply, but still require a part of batteries to realize energy storage.

From the above summary, the left atrial appendage occlusion device in the prior art still has the following problems:

1. after the installation of the current left auricle plugging device, in order to observe the postoperative condition of a patient to prevent complications, an electrocardiogram monitoring device is additionally required to be worn for monitoring, which is very troublesome;

2. most of the implanted monitoring devices have built-in batteries, which are wireless power supply, but still require a part of batteries to store energy, and the batteries contain substances harmful to human bodies, which are potentially dangerous.

Based on the above, the utility model provides a left auricle plugging system capable of wirelessly supplying energy and wirelessly monitoring electrocardio to solve the above problems.
