A device (1102) for containing bone graft material, comprising:a first shell member (1102a) defining a first portion of an inner sleeve (1112a) and a first portion of an outer sleeve (1114a) to form a first bone graft collecting space (1132a) therebetween；a second shell member (1102b) defining a second portion of an inner sleeve (1112b) and a second portion of an outer sleeve (1114b) to form a second bone graft collecting space (1132b) therebetween, the first and second shell members (1102a, 1102b) couplable to one another such that, when the first and second shell members (1102a, 1102b) are coupled to one another in a closed configuration, a contour of the outer sleeve (1114a, 1114b) substantially matches a contour of an exterior of a bone about which the device (1102) is to be employed.骨移植材料を含む装置は、骨移植片採取空間（１３２）がその間に形成されるように、近位端から遠位端まで長手方向に延在する内側スリーブ（１１２）と、内側スリーブを取り囲み、かつ近位端から遠位端まで長手方向に延在する外側スリーブ（１１４）とを含む本体（１０２）を備える。骨移植片を前記採取空間に採取するためのシステム（１０１）も提供する。【選択図】図１および図３
