An artificial vertebral body includes a housing, a rotating body and a support member; an inner peripheral surface of the housing is provided with a first cooperating portion. The rotating body is rotatably disposed in the housing, an outer peripheral surface of the rotating body being provided with a second cooperating portion; the first cooperating portion can cooperate with the second cooperating part to restrict the rotation body to only rotate clockwise or counterclockwise; the support member passes through the rotating body and is screwed together with the rotating body; and the rotating body can rotate relative to the housing to drive the support member to move along the axial direction of the rotating body.

Artificial vertebral body

A pad prosthesis includes a body, a protrusion portion and a snap. The body has a first surface, and the first surface includes a front edge, a curved edge, a rear edge and a straight edge connected sequentially. The protrusion portion is arranged on the first surface of the body. The snap is arranged on the first surface of the body, and the snap extends along a second direction, an angle between the second direction and the first direction is an acute angle. The pad prosthesis according to the present application may be applied in an artificial knee prosthesis.

The present disclosure provides an automated warehousing system, a display panel production line and a logistics delivery method. The automated warehousing system includes a plurality of zones, a server host, a controller, and at least one moving device. Each zone corresponds to one manufacturing process for an in-process product. The server host is configured to manage production information of the in-process product and send the production information to the controller. The controller is configured to, based on the received production information, after completion of one corresponding manufacturing process, control the moving device to move the in-process product to the zone that corresponds to the next manufacturing process to be performed at the in-process product.

Automated warehousing system, display panel production line and logistics delivery method

A femoral prosthesis and a knee prosthesis are provided. The femoral prosthesis includes a condyle surface having a first surface section contacting a tibial joint surface over a first range of flexion angles and a second surface section contacting the tibial joint surface over a second range of flexion angles; the first range of flexion angles from a first to a second flexion angle; the second range of flexion angles from the second to a third flexion angle; the first flexion angle selected from &#x2212;20&#xb0; to 0&#xb0;, the second flexion angle selected from 45&#xb0; to 75&#xb0;, the third flexion angle selected from 50&#xb0; to 90&#xb0; and the third flexion angle greater than the second flexion angle; the first surface section having a radius of curvature of a constant length, and the second surface section having a radius of curvature that decreases from a front end to the rear end.
