PROBLEM TO BE SOLVED: To provide an excision assembly of the patella equipped with a handle, a slide member, and two nail members.SOLUTION: The slide member is mounted on the handle in a movable fashion and includes two branched arms. The inner peripheries of the branched arms have contact with the outer periphery of the nail member as the slide member moves far and then the nail members move in opposite directions closing in the periphery of the patella. The nail members and slide member have teeth for holding the patella as the nail members move all together. The nail members have a flat surface of the same plane for guiding a passage of a saw blade during excision of the patella.COPYRIGHT: (C)2013,JPO&INPIT【課題】ハンドルと、摺動部材と、2つの爪部材とを備える膝蓋骨切除アセンブリを提供する。【解決手段】摺動部材は、移動可能にハンドルに取り付けられ、2つの分岐アームを含む。それらの分岐アームの内縁は、摺動部材の遠位移動によって爪部材が互いに向かって移動して膝蓋骨の周囲で閉じるように爪部材の外縁に接する。爪部材及び摺動部材は、爪部材がともに移動するにつれて膝蓋骨を把持するための歯を有する。爪部材はまた、膝蓋骨の切除中に鋸刃の通り道を案内するための平らな同一平面上の表面も有する。【選択図】図1
