ABSTRACT:

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a device for securing a bone during surgery. More particularly, this invention relates to a cerclage band that can securely bind a bone to prevent splintering of the bone during surgery.
BACKGROUND OF THE INVENTION
Cerclage bands are known (WO 9426192) in which a tightening buckle, which is connected to one end of a band part, has two side walls comprising openings which lie opposite one another and in which a tightening shaft is mounted which is intended for tightening the free end of the band.
Conventional hose clamps are known in which the openings for mounting the tightening shaft have a locking tooth and, in the area of the two openings, the tightening shaft has interacting teeth. A peg-shaped handling part protrudes from the tightening buckle on one side for engagement of a key.
SUMMARY OF THE INVENTION
This invention provides a cerclage band that can securely bind a bone to prevent splintering of the bone during surgery. In one embodiment, the cerclage band comprises a band part, a tightening buckle and a tightening shaft. The tightening buckle is connected to one end of the band part. The tightening buckle has a first side wall and a second side wall. The two side walls enclose a space for receiving a free end of the band part. The first side wall has a first opening having a locking tooth, and the second side wall has a second opening. The tightening shaft is mounted inside the first and second openings. The tightening shaft has toothing that can interact with the locking tooth of the first side wall while the tightening shaft is in a untoothed area of the second opening. The first opening is oblong so that the tightening shaft can be moved out of engagement with the locking tooth.
Preferably, the tightening shaft has a handling part. Preferably, the second opening is oblong shape. Preferably, the handling section is peg shaped and is arranged on the side of the first opening.
