Problems solved by technology

In order to ensure the clamping effect, it is necessary to use wider clamp arms. However, in the prior art, the two clamp arms of the valve clamp are fixed on the base in a mating manner and a connecting rod is used to drive the clamp arms to open and close. As a result, the size of the base of the clamp is relatively large, and multiple connecting rod parts also result in a long axial dimension of the clamp, requirin

Abstract

The invention provides an anti-slip valve clamping device and a valve clamping system. The valve clamping system comprises a pushing device and a valve clamping device. The valve clamping device comprises a base and at least two tong arms which are opened and closed relative to the base, each tong arm comprises a connecting end and a free end, the connecting ends of the at least two tong arms arerotationally connected with the base through the same rotating shaft, and the connecting ends of the at least two tong arms are partially staggered. According to the valve clamping device, the connecting ends of the at least two forceps arms are rotationally connected to the base through the same rotating shaft, and the connecting ends of the at least two forceps arms are partially staggered, so that the valve clamping device is small in overall size and light in weight, conveying is convenient, and the anti-slip performance is high.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an anti-slip valve clipping device and a valve clipping system. Background technique [0002] see figure 1 , the mitral valve 1 is a one-way valve located between the left atrium 2 and the left ventricle 3 of the heart. A normal and healthy mitral valve 1 can control blood flow from the left atrium 2 to the left ventricle 3 while preventing blood flow from the left ventricle 3 to the left atrium 2. The mitral valve 1 includes a pair of leaflets called an anterior leaflet 1a and a posterior leaflet 1b. The anterior lobe 1a and the posterior lobe 1b are fixed to the papillary muscle of the left ventricle 3 through the chordae 4 . Under normal circumstances, when the left ventricle 3 of the heart contracts, the edges of the anterior lobe 1a and the posterior lobe 1b are completely joined to prevent blood from flowing from the left ventricle 3 to the left atrium 2 . see figure 2 ...
