Embodiment Construction

[0045] Attached to the following Figure 1-4 This application will be described in further detail.

[0046] The embodiment of the present application discloses an atrial appendage clip. refer to figure 1 and figure 2, the auricle clip includes a binding wire 1 and a guide rod 2, wherein, the binding wire 1 is a rigid wire with elastic deformation ability, and the material of the binding wire 1 is a common plastic material used in medical treatment, such as rigid silicone, polyester resin or poly tetrafluoroethylene, etc., to reduce the influence of the binding wire 1 itself on the patient's physical condition.

[0047] refer to figure 1 and image 3 , the binding wire 1 includes a threading end 11 and a free end 12. The threading end 11 is provided with a threading hole 111. After the free end 12 passes through the threading hole 111, the binding wire 1 is surrounded by a binding ring 13 for clamping the left atrial appendage. A plurality of ratchet teeth 14 are evenly ...

Abstract

The auricle clamp comprises a binding line and a guide rod, the binding line is a hard line with elastic deformation capacity and comprises a threading end and a free end, the threading end is provided with a threading hole, and after the free end penetrates through the threading hole, the binding line defines a binding ring used for binding and sealing a left auricle. A plurality of ratchets are evenly distributed on the inner side of the bundling ring, and barbs used for being connected with the ratchets in a clamped mode to prevent the bundling ring from expanding are fixedly connected to the inner wall of the threading hole. The guide rod is used for guiding and conveying the bundling ring to an operation position, the guide rod comprises an operation end, a holding part and a connecting part connecting the operation end and the holding part together, a guide channel is formed in the guide rod in the length direction of the guide rod, and two orifices of the guide channel are located in the operation end and the holding part respectively. The free end of the bundling line penetrates through the guide channel. According to the auricle clip, the size of a wound needing to be cut in an operation is reduced, shielding of the auricle clip on the operation view is reduced, and therefore the risk of the operation is reduced.

Description

technical field [0001] The present application relates to the field of medical devices, in particular to an atrial appendage clip. Background technique [0002] Atrial fibrillation (AF) is the most common arrhythmia disorder, and its symptoms are irregular heartbeats, of which non-valvular atrial fibrillation is a high incidence type of atrial fibrillation. The left atrial appendage is an accessory structure of the left atrium of the heart. It is a long, narrow, curved tubular shape with a narrow apex, rich in pectinate muscles and trabeculae. The entrance of the left atrial appendage in patients with atrial fibrillation is significantly widened, and the atrial appendage loses effective and regular contraction. In non-valvular atrial fibrillation, more than 90% of thrombus formation is associated with the left atrial appendage. [0003] At present, there are three main ways to prevent stroke in patients with atrial fibrillation: the first is to use anticoagulant drugs such...
