Embodiment 1
[0030] figure 1 It is a structural schematic diagram of the valve leaflet cutting device of the present invention; figure 2 It is a structural schematic diagram of the positioning unit of the present invention.
[0031] This embodiment discloses a valve leaflet cutting device, such as figure 1 As shown, it includes positioning unit, control unit and cutting unit.
[0032] Such as figure 2 As shown, the positioning unit includes a leaflet template 3, a light box 1 and an imaging device 2 placed above the light box; the leaflet template 3 is an opaque plastic plate that is different in color from the pericardial material 6 of the animal. The leaflet template 3 has the same shape as the leaflet of the valve to be cut. The leaflet template 3 is divided into two groups according to the model of the valve leaflet, and each group has three pieces. The imaging device is a conventional camera, which is used to record the position of the leaflet template; the light box is provide...
Embodiment 2
[0036] This embodiment discloses a valve leaflet cutting method, using the valve leaflet cutting device described in Embodiment 1, specifically including the following steps:
[0037](1) Use scissors to trim a corner and a side of the animal pericardium material, spread the animal pericardium material on the light box, make the corner coincide with the origin, and align one side with the X axis;
[0038] (2) Turn on the light box, the light emitted by the light box passes through the animal pericardium material, judge the thickness of the animal pericardium material and the texture direction of the tissue according to the intensity of the light passing through the animal pericardium material, and determine the leaflet according to the thickness and texture orientation of the animal pericardium material The appropriate cutting position, direction and model, and place the two valve leaflet templates at positions suitable for cutting valve leaflets;
[0039] (3) The camera equipm...
