摘要:
A reamer has a flexible carbon fiber composite shaft coupled to an interface element by wrapping a carbon fiber material so as to provide a reliable connection between the shaft and the interface element while maintaining flexibility of the shaft. The reaming device shaft has a mounting portion, the mounting portion having an end face and an outer surface. An interface element for mechanical coupling of an external device is provided and comprises a mounting portion, the mounting portion having an end face and an outer surface. The end face of the shaft mounting portion and the end face of the interface element mounting portion are facing towards each other and a carbon fiber wrapping is provided extending over both the outer surface of the shaft mounting portion and the outer surface of the interface element mounting portion
摘要:
A reaming device comprising a shaft with a mounting portion, the mounting portion having an outer surface; a carbon fiber layer located on the mounting portion outer surface; an injection molded interface element for mechanical coupling of an external device molded on the carbon fiber layer, the interface element having a mounting portion; wherein the carbon fiber layer extends over the outer surface of the shaft mounting portion and having an outer surface, wherein the carbon fiber layer outer surface has a non-smooth surface structure; wherein the injection molded interface element mounting portion is injection molded over the carbon fiber layer surface structure The method according to claim 12, further comprising preparing of shaft mounting portion before wrapping a carbon fiber layer for establishing a reliable connection between the shaft and the carbon fiber layer.

A drill guide for a bone plate which has holes therethrough for receiving bone screws. The drill guide includes a guide block having drill guide bores alignable with at least two bone screw receiving holes in the bone plate. A first locking element in inserted through a guide block drill guide bore. The locking element has a tip for engaging a bone screw receiving holes in the bone plate, the tip being selectively expandable to engage and disengage from the bone plate hole. A second locking element is mounted on the guide block and is engageable with a bone plate hole. The second locking element also has a tip for resiliently engaging walls of the bone plate hole wherein the tip of the first and second locking elements has a split portion. The first and second locking elements include an axially moveable rod for expanding the split tip portion to engage the plate

An implant system for use in orthopedic surgery for fixation of bone includes an intramedullary nail and a coupling unit. The intramedullary nail has a medial side, a lateral side and a proximal portion defining a longitudinal axis. The proximal portion includes a bore defining a first axis substantially parallel to the longitudinal axis of the proximal portion and a transverse bore configured to receive a bone fastener. The coupling unit is movably arranged within the bore of the proximal portion and includes one or more bone fastener engagement members at one or both of the lateral side and the medial side of the intramedullary nail.

An implant system for use in orthopedic surgery for fixation of bone includes an intramedullary nail and a coupling unit. The intramedullary nail has a proximal portion defining a longitudinal axis and a transverse bore. The proximal portion includes a bore defining a first axis and a guiding structure defining a second axis, wherein the first axis and the second axis are substantially parallel to the longitudinal axis of the proximal portion of the intramedullary nail and are spaced apart from each other. The coupling unit is movably arranged within the proximal portion and includes a substantially cylindrical pin and a drive member with a through hole. The guiding structure is configured to slidably receive the substantially cylindrical pin, such that the pin can engage within a groove of a bone fastener configured to penetrate the transverse bore of the intramedullary nail.
