The application discloses a meniscus suture device which comprises an axis extending in an extending direction, and comprises a puncture needle, a pushing needle and a handle; the pushing needle is coaxially arranged with the puncture needle and movably arranged in the puncture needle; the handle is internally provided with a pushing assembly and a rotating assembly; the pushing assembly is arranged on one side of the rotating assembly close to the proximal end; the pushing assembly is connected with the pushing needle to push the pushing needle to move in the extending direction; the rotating assembly is connected with the puncture needle to realize rotation of the puncture needle by the extending direction as an axis by a preset angle. The application realizes rotation of the puncture needle by the preset angle by the rotating assembly, solves the problem that the puncture needle of the current meniscus suture device cannot rotate left and right, and simultaneously, the rotating assembly can be adopted to accurately control the rotation angle of the puncture needle, and the puncture range of the distal end of the puncture needle is expanded.

The utility model belongs to the technical field of color master batch processing, particularly relates to a color master batch raw material dispersing device, and provides the following scheme aiming at the problems that a processing container is inconvenient to assemble and disassemble, difficult to clean and maintain, unfavorable for continuous processing of raw materials and the like in an existing integrated device. A containing groove is formed in the inner wall of the bottom of the supporting frame, and a processing barrel is placed in the containing groove. The color master batch raw material dispersing device further comprises a cover plate, the cover plate is arranged in the supporting frame, the cover plate is located above the processing barrel, the color master batch raw material dispersing device is designed in a separated mode, the processing barrel is convenient to assemble and disassemble, the processing barrel can be taken out by taking out the limiting pin and moving out the rotary disc after processing is finished, and raw material adding, raw material taking and processing barrel maintaining and cleaning are facilitated; the switching assembly can complete switching between height adjustment and rotation of the rotary table, rotation and lifting driving can be achieved only through one motor, and the equipment manufacturing cost is reduced.
