Position；Then ascending pipe is injected in human body bone, another hand press sleeve connecting handle, due to spiral shell in the second of through-hole wall
Line is threadedly coupled with the second external screw thread so that tamper component is rotated along hand of helix and glided, to by the artificial of required implantation
Bone, allograph bone or autologous bone are compacted at the position for wanting bone grafting, and due to the presence of spring, cover assembly can be subject to downward bullet all the time
Power, is fixed on funnel port and moving along tamper pole length direction does not occur, simultaneously because unidirectional latch is subject to the first clamp
Limitation, makes cover assembly keep opposing stationary with funnel；It is broken again without active force with bone when tamper body lower end, socket ring will be pressed
Hand, which unclamps while holds tamper bar, to be allowed to not rotate, and tamper bar is merely lifted up, due to the second of through-hole wall
Internal thread is threadedly coupled with the second external screw thread of tamper component, and since unidirectional latch at this time is from the limitation of the first clamp, lid
Body component can be rotated relative to stamp stem, drive plectrum to be rotated relative to funnel so as to be attached to broken bone the pushing away in plectrum of inner wall of hopper
To movement among funnel under dynamic, eventually fall into ascending pipe；Repeat the above steps, it becomes possible to be easily accomplished bone grafting operation.
