Abstract: A cell activation reactor and a cell activation method are provided. The cell activation reactor includes a body, a rotating part, an upper cover, a microporous film, and multiple baffles. The body has an accommodating space, which is suitable for accommodating multiple cells and multiple magnetic beads. The rotating part is disposed in the accommodating space and includes multiple impellers. The microporous film is disposed in the accommodating space and covers multiple holes of the accommodating space. The baffles are disposed in the body. When the rotating part is driven to rotate, the interaction between the baffles and the impellers separates the cells and the magnetic beads.

Abstract: A device for fixing soft tissue. A sleeve is detachably connected to a self-drilling tapping screw, moving and rotating the self-drilling tapping screw. A guide bar is detachably connected to the self-drilling tapping screw and fit in the sleeve. A fixing pin is fit in a washer and connected to the self-drilling tapping screw. The guide bar is detachably fit in the fixing pin. The fixing pin abuts the washer and the self-drilling tapping screw.

Abstract: A spinal dynamic stabilization device is provided, including at least a main portion, at least a supporting structure, and a sliding bar. The main portion includes a guiding groove. The supporting structure includes two wing portions. The wing portions pivot on the main portion. The sliding bar connects to the supporting structure and moves in the guiding groove. When the sliding bar moves in the guiding groove, the wing portions expand rotatably toward the adjacent vertebrae of the spine of the patient by the sliding bar.
