摘要： Provided is a bone fixation band which can be easily handled, enables to securely fasten the bone, and also to prevent the post-operative inconveniences by forming the head part as thin as possible. The band head of the bone fixation device is constituted of a plate being bent in roughly an N-letter shape. The plate comprises three through-holes arranged in the extended direction of the band. The band is passed through into the through-hole just like sawing and then is folded back to pass through again into the through-hole and fixed. A sharp and curved needle is provided at the tip of the band for easily being set around the bone to be a fixation target and also for making a hole in the bone so that the band can be easily passed through.

摘要： An apparatus for manufacturing stiffness-taper tubing includes a die having an extrusion hole, a die holder for holding the die, and a mandrel mounted inside the die holder and that fits in the extrusion hole. The apparatus forms stiffness-taper tubing by switching between and supplying resins having different stiffnesses over the mandrel from a plurality of resin-supply ports formed in the die holder such that the stiffness gradually changes in the lengthwise direction. A mandrel insertion hole connecting to the extrusion hole is formed in the die holder and the mandrel is mounted in this mandrel insertion hole. The plurality of resin-supply ports open to a cylindrical space formed between the inner surface of the mandrel insertion hole and the outer surface of the mandrel at a position separated from the extrusion hole in the die, and the plurality of resins flow together in this space.

摘要： A stiffness-taper tubing and a manufacturing method and apparatus for such, in which the bonding strength in a transition section between resins having different stiffness is increased, where the length of the transition section is shortened and operability is improved, and where the volume of residual resin when switching resins is reduced as well as the degradation of the quality of residual resin due to heating is suppressed. An apparatus for manufacturing stiffness-taper tubing may include a mandrel having a mixing portion, which is tapered and has projections formed thereon.
