Disclosed are a laser scanning device, a radar device, and a scanning method thereof. The laser scanning device comprises a scanning prism comprising a plurality of scanning mirror surfaces, wherein the plurality of scanning mirror surfaces rotates about a scanning axis, a normal of each of the scanning mirror surfaces forms a certain angle with respect to the scanning axis, and the angles thereof are not all the same; a transceiving component comprising a laser transmitting unit and a laser receiving unit, wherein the laser transmitting unit generates a scanning line by rotation of the scanning mirror surfaces, and the same laser transmitting unit generates a plurality of scanning lines by rotation of the scanning prism.

The present disclosure discloses a knot-tying device and a knot-tying system with the knot-tying device. The knot-tying device comprises a shear knife provided at a front end of a driving rod. Hilts of the shear knife () are opened by an elastic member, and the hilts are pressed by the driving rod to close and cut a suture. The shear knife is used as a substitute for a cutter in the related art, and is driven to close by the driving rod so as to realize a shearing function. When the suture is cut off by the shear knife, a requirement for sharpness of blades are greatly reduced, and the blades are able to be realized by a common processing method, thereby greatly reducing cost while ensuring reliability. In addition, abrasion on the blades from the suture is reduced, thereby greatly prolonging the service life of the product.
