Second female thread and second external screw thread of wall are threaded so that tamper assembly rotates along hand of helix and glides, in order to by institute
Artificial bone, allograph bone or the autologous bone that need to implant are compacted at the position wanting bone grafting, and due to the existence of spring, cover assembly all the time can
By downward elastic force, it is fixed on funnel port and the movement along tamper pole length direction does not occur, simultaneously because unidirectional latch is subject to
To the restriction of dop, cover assembly is made to keep geo-stationary with funnel；When tamper body lower end and osteomiosis are again without active force, will pressing
The hands of set T-Ring unclamps to be held tamper bar simultaneously and is allowed to not rotate, and is merely lifted up by tamper bar, due in through hole
Second female thread of wall is threadeded with the second external screw thread of tamper assembly, and owing to the most unidirectional latch is not limited by dop
System, cover assembly can rotate relative to stamp stem, drives plectrum to rotate relative to funnel to be attached to the broken bone of inner wall of hopper at plectrum
Promotion under mobile in the middle of the funnel, eventually fall in ascending pipe；Repeat the above steps, it becomes possible to be easily accomplished bone grafting operation.

Detailed description of the invention
Below according to accompanying drawing, detailed description of the invention of the present utility model is made a detailed explanation.
According to shown in Fig. 1 to Fig. 9, the present embodiment is a kind of orthopaedics bone grafting external member, it is characterised in that: include the leakage of cone
Bucket 1, cover assembly 4, spring 5 and tamper assembly 6.
Described funnel lower end forms ascending pipe 11；Described ascending pipe outer wall has offered sliding tray 111 along its length；
The equidistant positioning port 1111 offered obliquely in described sliding tray side；Described funnel outer wall forms head rod 2；
Described funnel and head rod intersection form the first dop 12；The described head rod other end forms handle 3；
Described handle upper end end face forms anti-slip tank；Described ascending pipe slidably connects positioning sleeve 8, and described positioning sleeve inwall sets
