Abstract: A spirally-wound battery structure and a method for producing the same is provided. In the method, a power-supplying electrode plate spirally winds a hollow cylinder and has first conductive tabs and second conductive tabs. A first conductive terminal plate and a second conductive terminal plate are inserted into the hollow cylinder. Conductive welding sheets sleeve the conductive terminal plates to clamp the conductive tabs between the conductive welding sheet and the conductive terminal plate. The conductive welding sheet, the conductive tabs, and the conductive terminal plate are welded with laser. A casing encapsulates the hollow cylinder, the power-supplying electrode plate, the first conductive tabs, the second conductive tabs, the first conductive welding sheet, and the second conductive welding sheet. The first conductive terminal plate and the second conductive terminal plate penetrate through the casing.

Abstract: The invention provides a bone cement mixing assembly including a mixer, a syringe barrel and a movable plug cover. The mixer includes a stirring rod and a stirring barrel. The stirring rod has holding end, a rod body and a stirring end. The stirring barrel has a barrel cover, a first barrel open, a first barrel body, a first barrel bottom, and a stirring space located in the first barrel body. The syringe barrel has a second barrel open, a second barrel body, a second barrel bottom, and an injection space located in the second barrel body. In this way, the complete-stirred bone cement in the stirring barrel can be directly collected and pushed into the syringe barrel through the movement of the movable plug cover to achieve the effect of completing the preparation of the bone cement quickly and efficiently.
