Valve clamping device capable of detecting clamping state of valve and valve clamping system

Abstract

The invention provides a valve clamping device capable of detecting the clamping state of a valve and a valve clamping system. The valve clamping system comprises a pushing device and the valve clamping device. The valve clamping device comprises a clamping device body and a detection assembly. The clamping device body comprises a push rod, a near-end clamping piece and a far-end clamping piece; the near-end clamping piece and the far-end clamping piece can be unfolded relative to the push rod in a radiation mode; a valve containing space is formed between the near-end clamping piece and the far-end clamping piece; and the near-end clamping piece and the far-end clamping piece are matched to clamp valve tissue located in the valve containing space. The detection assembly comprises a probe and a traction wire used for driving the probe to move; the traction wire can drive the probe to be inserted into the valve containing space so as to detect the clamping state of the valve tissue in the valve containing space. According to the invention, the traction wire drives the probe to move, the probe is inserted into the valve containing space, and the clamping state of the valve tissue in the valve containing space can be detected, so that the operation is easy, the operation time is shortened, and the operation efficiency is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a valve clamping device and a valve clamping system capable of detecting the clamping state of a valve. 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...

Problems solved by technology

However, when detecting the clamping state of the valve leaflet based on the visualization of the detection element, since the parts of the valve clamp are mostly metal, it will interfere with the position judgment of the detection element under color ultrasound, and doctors cannot intuitively evaluate the clamping effect of the valve leaflet. Moreover, the detection element is generally small, and the actual imaging effect is poor. Therefore, the operation time is long and the efficiency is low; and when the current integrity of the sensor and the detection circuit is used to detect the clamping state of the valve leaflet, it is necessary to install a conductive valve on the valve clamp. The detection element or sensor of the implanted valve clamp becomes an electromechanical device instead of a purely mechanical device, which reduces the safety of the device, and requires the use of external equipment to detect the clamping state of the valve leaflet, which increases the operation cost. And the operation process is cumbersome, the operation time is long, and the efficiency is low
