Left auricle closer conveying system

Abstract

The invention discloses a left auricle closer conveying system. The left auricle closer conveying system comprises a control handle, a connecting rod and a head end, wherein the control handle is connected with the head end through a connecting rod; two clamping arms are arranged on the head end, and a closer is loaded between the two clamping arms; direction control ends, a field angle control end and a loading removal control end are arranged on the control handle; a direction control line is connected between the direction control ends and the head end, and the direction control ends can control the direction of the head end through the direction control line; a field angle control line is connected between the field angle control end and the two clamping arms, and the field angle control end can control the inclined angle of the two clamping arms through the field angle control line; and a loading removal control line is connected between the loading removal control end and the closer, and when the loading removal control line is disengaged from the closer by the loading removal control end, the closer is subjected to loading removal from the clamping arms. The invention aims to provide the left auricle closer conveying system which can reduce wound to a patient in the surgery process, and can accurately release the closer so as to clamp and close a left auricle.

Description

technical field [0001] The invention relates to a surgical instrument, in particular to a left atrial appendage closure delivery system suitable for minimally invasive surgery. Background technique [0002] Atrial fibrillation, short for atrial fibrillation, is one of the most common cardiac arrhythmias. Among stroke patients, 20% are related to AF, and 35% of AF patients will experience one or more thromboembolisms in their lifetime. Atrial fibrillation is an independent risk factor for mortality. The stroke rate of patients with atrial fibrillation is 5 times higher. The primary treatment goal of atrial fibrillation is to prevent stroke and improve symptoms. 90% to 100% of non-rheumatic heart disease patients with atrial fibrillation thrombus originates from the left atrial appendage. [0003] Evidence-based medicine has proved that sealing the left atrial appendage can prevent the occurrence of embolism complications in patients with atrial fibrillation. Clinically, ca...

AI Technical Summary

Problems solved by technology

Existing delivery systems are unreliable in releasing the occluder, resulting in the inability of the occluder to accurately close the LAA

In addition, when the occluder is detached from the delivery system, surgical scissors must be used to cut the thread so that the occluder can be detached from the delivery system, which requires a larger surgical path, which will cause greater trauma to the patient
