An external skeletal fixation device includes first and second pin clamp units fixedly holding rodlike members inserted, respectively, into a first part and a second part of a bone on the opposite sides, respectively, of a virtual hinge point corresponding to a center of rotational angulation, a center on opposite sides of a fracture site of the bone or a part of the osteotomy site for deformity correction are turned, or a center about which a joint turns. A connecting mechanism connecting the first and second pin clamp units has first and second arms pivotally connected to the first and second pin clamp units, respectively. The respective axes of rotary joints respectively connecting the first pin clamp unit and the first arm, the second pin clamp unit and the second arm, and the first arm and the second arms extend toward the virtual hinge point.

External skeletal fixation device

A structure for inserting an insert member of an attachment, etc., into a concave receptacle portion embedded in a shoe sole and removably pinching and fixing the insert member inside the concave receptacle portion with an elastic member, the structure being capable of permitting the removal of the attachment with a wrench for a screw. The structure is constituted as follows. First, the structure has a concave receptacle portion embedded in a shoe sole and an attachment having an attaching/detaching tool fitting portion formed on the shoe sole side and an insert member that is to be inserted into the concave receptacle portion and is formed on the opposite side. Second, the insert member is inserted into the concave receptacle portion, and inside the concave receptacle portion, the insert member of the attachment is removably pinched and fixed with an elastic member. Third, a pushing-up gradient surface is formed on one side of the concave receptacle portion side or the insert member side, and a copying portion for copying the pushing-up gradient surface is formed on the other side. Fourth, the attachment is turned with an attaching/detaching tool to remove the insert member from the concave receptacle portion.

Connector for attaching and detaching attachment to/from shoe sole

A connector includes an insert member for seating within a socket embedded in a shoe sole wherein it is removably fixed with an elastic member, the connector permitting the removal of the attachment with a wrench engaging a tool fitting portion formed on the shoe sole side. A first camming surface is formed on the socket and a second camming surface is formed on the insert member. The insert member is removed from the socket using a wrench to turn the second camming surface relative to the first camming surface.
