Abstract: A surgical rasping and/or shaving system functions in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping and/or shaving head which may be low profile and offer a flat cutting/rasping/shaving surface, or with a cutting head with at least one cutting edge. The tissue removal member is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the system to provide ablation or coagulation of soft tissues.

Abstract: A surgical instrument system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system comprises a cutting head which includes jaw members which may be urged between open and closed positions to providing a biting or chewing action for removal of targeted tissues. The instrument system is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion to open and close the jaw members. Suction for removal of bone fragments or other tissues is provided through a suction opening.

Abstract: A soccer helmet includes a generally dome-shaped padding layer and a generally dome-shaped shell layer fitting over and attached to the padding layer. The padding layer might have a substantially uniform thickness of approximately ⅜ inches. The shell layer is smooth and has some rigidity such that when the soccer helmet is being worn on a human head, the ball rebounds from the shell layer in about the same direction and with about the same speed, or with a greater speed, than the soccer ball would if rebounded off an unprotected human head. Therefore, the soccer helmet does not interfere with heading a soccer ball. The soccer helmet protects the head from repetitive blows due to, for example, heading. Furthermore, the soccer helmet protects the head from single event injuries such as collisions with goal posts, the ground, and other players' head, knee, elbows, and feet.
