A system and method for performing an opening wedge osteotomy in a tibia, the system and method comprising (i) a positioning guide configured for aligning a portion of the positioning guide with a joint line of the tibia and for fixing the positioning guide to the tibia; (ii) a cutting guide configured to direct a cutting blade into the tibia so as to form a bone cut therein; (iii) a mechanical jack configured for placement into the bone cut in the tibia so as to distract the tibia at the bone cut; and (iv) a multi-part implant for supporting the open wedge osteotomy in the tibia, with a first component for disposition in a posterior portion of the open wedge osteotomy, a second component for disposition in an anterior portion of the open wedge osteotomy, and a connection device for selectively connecting the components to one another.

Apparatus and surgical techniques provide alternative cutting fixtures and other features to improve bone resection accuracy and joint stability. According to one embodiment, stabilizers are removably attached to a cutting guide to temporarily lengthen the surface against which a saw or other cutting device rests. Another embodiment provides differently shaped saw blades, having curved distal ends and right-angle bends applicable to box cuts of the type associated with cruciate sacrifice knee-replacement surgery. Methods are also disclosed whereby the box cuts, distal and posterior augment cuts may be approached from a distal perspective, both laterally and medially. A different embodiment provides a trial / cutting guide having flat surfaces as opposed to curved surfaces adapted for articulation within a joint. Yet a further alternative embodiment teaches a device for determining the joint line relative to a tibia using the fibula as reference.

A direct-view-type display device (100a) is provided with: a display panel (10), which has a display region (31) and a frame region (30) formed outside the display region; and a light guide element (20), which has a light incoming surface (21), a light outgoing surface (22), and a plurality of light guide sections formed between the light incoming surface (21) and the light outgoing surface (22). The light guide sections include a transparent section, and at least a part of the side surface of the transparent section is provided with a metal section. The light incoming surface (21) of the light guide element (20) overlaps a part (32) of the peripheral display region adjacent to the frame region (30) of the display panel (10) along a first axis (J1), and the light incoming surface is arranged in parallel to the surface of the display panel (10). In the light outgoing surface (22) of the light guide element (20), the distance from the light incoming surface (21) increases along the first axis (J1) toward the frame region (30) from the part (32) of the peripheral display region. Thus, the direct-view-type display device wherein the frame region of the display panel or a joint line formed when tiling is performed is not easily seen is provided with the structure which is simpler and lighter in weight compared with conventional structures.

An expanding plug for tendon fixation features a two-part system in which an expansion pin fits inside a fixation sleeve. The fixation sleeve is configured to expand diametrically to achieve interference fixation of a graft tendon inside of a bone tunnel. Fixation sleeve expansion is urged by a two-step engagement of the expansion pin. The tendon graft is assembled to the expanding bolt and situated within a bone tunnel. Passing suture is used to pull a joint-line end of the expansion pin into the tunnel to partially expand the fixation sleeve at the joint-line end. Pulling a graft end of the expansion pin toward the joint line expands the fixation sleeve to place the expanding plug in the fully deployed configuration.

A deposition friction stir weld process of joining work pieces includes placing a filler material on and about a joint line formed by butting a first work piece surface against a second work piece surface; and frictionally heating the filler material to soften the filler material and portions of the first and second work piece surfaces in thermal contact with the filler material and form a weld between the first and second work pieces, wherein frictionally heating is at a temperature below a melting point of the filler material and the first and second workpiece surfaces. Also disclosed herein are friction stir welding assemblies for providing the deposition friction stir weld as well as processes for depositing filler material and contouring a workpiece surface.

The invention belongs to the technical field of a welding machine, and particularly relates to a creeping-type automatic tracking seam welding machine, which is characterized in that: a slide plate which can move transversely along a base is arranged on the base, a compression spring is arranged between the slide plate and the base, the slide plate is provided with a slide platform which moves longitudinally along the slide plate, a compression spring is arranged between the slide plate and the slide platform, the slide platform is provided with a cantilever, one side on the outer end part of the cantilever is provided with a roller which rolls along an annular seam of a work-piece to be welded, a welding torch is arranged on the cantilever at one side of the roller, a joint line of centers of the welding torch and of the roller is parallel to a central line in the length direction of the cantilever, and one side of the line of centers of the welding torch and the roller is provided with a press block or a press wheel for pressing one side welding element or an outer layer welding element. The automatic tracking seam welding / cutting manipulator has beneficial effects that: the automatic tracking seam welding / cutting manipulator has a simple structure and low production cost, is convenient to install, repair and use, can automatically track a seam trace to realize the movable welding, has high welding quality, and is suitable for seam welding annular weld seams.
