Position；Then ascending pipe is injected in human body bone, another hands press sleeve connecting handle, due to spiral shell in the second of through-hole wall
Stricture of vagina and the second external screw thread are threaded so that tamper assembly rotates along hand of helix and glides, artificial in order to by required implantation
Bone, allograph bone or autologous bone are compacted at the position wanting bone grafting, and due to the existence of spring, cover assembly all the time can be by downward bullet
Power, is fixed on funnel port and the movement along tamper pole length direction does not occur, simultaneously because unidirectional latch is by the second dop
Limit, make cover assembly keep geo-stationary with funnel；When tamper body lower end and osteomiosis are again without active force, by press sleeve T-Ring
Hands unclamps to be held tamper bar simultaneously and is allowed to not rotate, and is merely lifted up by tamper bar, due to the second of through-hole wall
Female thread is threadeded with the second external screw thread of tamper assembly, and owing to the most unidirectional latch is not limited by the second dop, lid
Body assembly can rotate relative to stamp stem, drives plectrum to rotate relative to funnel to be attached to broken bone the pushing away at plectrum of inner wall of hopper
Move in the middle of funnel under Dong, eventually fall in ascending pipe；Repeat the above steps, it becomes possible to be easily accomplished bone grafting operation.
