The design points of the design product: in shape. 4. The picture or photo that best indicates the design points: perspective view.

The present application relates to a kind of flexible capture device of heart mitral valve, including shell, drive mechanism, capture main body, spring compression mechanism and flexible capture mechanism, the inner wall of one end of shell is equipped with first track, variable track area and second track;Drive mechanism one end is equipped with first protruding tooth;Capture main body one end outer surface is equipped with second protruding tooth, and the other end face installs flexible capture mechanism;Second protruding tooth is contacted with first protruding tooth, located in first track or second track;Drive mechanism, capture main body and flexible capture mechanism are all connected with traction rope.Compared with prior art, the present application has by setting flexible capture mechanism, can fix mitral valve, solve valve reverse problem, can effectively reduce the phenomenon that medical surgical clip is not stable in surgery, to improve surgical efficiency;Capture device is cylindrical as a whole, each component is mutually nested, compact structure, is driven by traction rope, need not complex power structure, overall volume is small, and the advantages such as convenient operation.

The embodiment of the application discloses a method and device for judging mitral valve prolapse and pathological segmentation based on a heart ultrasound image; the method comprises the following steps: acquiring a heart ultrasound image to establish a heart ultrasound image data set; training and testing a small sample classification model based on a picture after noise reduction and preprocessing; obtaining a heart mitral valve medical image data set and a heart mitral valve prolapse image data set; inputting, training and verifying a pathological segmentation neural model; preliminarily verifying the pathological segmentation neural model to obtain a classification-segmentation model; sequentially inputting a new medical ultrasound image into the classification-segmentation model to detect whether classification and pathological segmentation are completed; and realizing automatic judgment and segmentation of the heart ultrasound image for the heart mitral valve prolapse, short analysis and processing time, high efficiency, and high medical image judgment accuracy.
