    摘要: A method of repairing a bone fracture comprises accessing a fracture along a length of a bone through a bony protuberance at an access point near an end of a bone. A bone fixation device is advanced into a space through the access point at the end of the bone. A portion of the bone fixation device is bent along its length to traverse the fracture. The bone fixation device is locked into place within the space of the bone.

    摘要: Apparatus for bone reinforcement, fixation and treatment of diseased or fractured bones including a supporting structure optionally coated with therapeutic agent is provided. The supporting structure or device may be collapsible upon deployment at the surgical site, and include fixation features such as anchors to securely position in place once deployed. Bone cement or other material may be provided to alternatively secure the positioned supporting structure for treatment. A lockable bone fixation device is described that comprises: a sleeve adapted to be positioned in a space formed in a bone; a guidewire adapted to guide movement of the sleeve; and an actuable lock adapted to secure the sleeve within the space of the bone from an end of the device.

    摘要: A handpowered, low cost, disposable laparoscopic surgical tool has a proximal hand engageable unit, an elongate extension unit and a distal jaw unit. Pulling a trigger of the hand engageable unit forwards an extension rod in the extension unit to pivot the jaws together. In one embodiment of the invention, the handle unit is primarily of molded plastic material for low cost and disposability. In an embodiment, electrocautery contact with the extension unit is through a bendable spring element. In an embodiment specially shaped links and connected jaw portions improve strength and control in opening and closing the jaws.
