Closing clip delivery system

Abstract

The invention discloses a closing clip conveying system. The system comprises a control handle, a connecting rod and a head end, the control handle is connected to the head end through the connectingrod, two clamping arms are hinged to the head end, a closing clip is loaded between the two clamping arms, a direction control end, an opening angle control end and a load shedding control end are arranged on the control handle, a direction control line is arranged between the direction control end and the head end in a connection mode, an opening device is arranged between the two clamping arms in a hinge mode, an opening angle control line is arranged between the opening angle control end and the opening device, and the opening angle control end controls the opening device to be opened or closed through the opening angle control line. When the opening device is opened or closed, the included angle between the two clamping arms is increased or decreased, and a load shedding control line is arranged between the load shedding control end and the closing clip in a connection mode. When the load shedding control end enables the load shedding control line to be disengaged from the closingclip, the closing clip is unloaded from the clamping arms. The invention aims to provide the closing clip conveying system which is smaller in conveying path, more accurate in control and more convenient to operate.

Description

technical field [0001] The invention relates to a medical device, in particular to a closure clip delivery system. 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, cardiac surgery uses special closing clips to close the left atr...

AI Technical Summary

Problems solved by technology

The head end of the existing conveying system cannot easily adjust the direction. When the closing clip is separated from the conveying system, it needs to be cut with surgical scissors to make the closing clip detached from the conveying system. The existing conveying system has a large conveying path and the operation is not convenient enough.
