Description

A kind of bone grafting driver

This utility model relates to the driver that bone grafting uses in a kind of bone surgery, belongs to field of medical appliances.

In bone surgery, usually need to carry out bone grafting, in the embedding sutura crack that plant bone mass can be firm in order to try to achieve, the bone piece need be pounded to the marrow in the slit, but the bone grafting driver that does not still have a kind of special use at present clinically, the clinicist can only utilize other apparatuses such as hammer handle, periosteal elevator that plant bone mass is squeezed into, its shortcoming is: (1) uses inconvenient: owing to other apparatuses such as hammer handle, periosteal elevator are not to design as bone grafting, therefore in use often be inconvenient to operate; (2) easily the bone piece is smashed: because other apparatuses such as hammer handle, periosteal elevator can not adapt with difformity bone piece, therefore in squeezing into process, often the bone piece is smashed, influenced the effect of bone grafting; (3) cause the abnormal waste of other apparatus.

The purpose of this utility model provides a kind of easy to operate, good to the bone block protection special-purpose bone grafting driver.

The purpose of this utility model is achieved in that it comprises the hammering handle and squeezes into head, characteristics are: an end of hammering handle is provided with the hammering seat, the other end is provided with adapter sleeve, squeezes into head and is provided with connecting rod, squeezes into head and flexibly connects by connecting rod, adapter sleeve and hammering handle.

Good effect of the present utility model is: (1) grips easily, thereby has made things convenient for operation technique, and be applicable to the bone grafting than the position, deep because this utility model has long hammering handle; (2) help protecting plant bone mass, can make the corresponding structure shape according to the difformity of bone piece, applied different parts, protection bone piece is not crashed to pieces.

Further specify this utility model below in conjunction with drawings and Examples.
