Surgical reamer

A modular tool connection assembly includes a housing which defines the main axis of assembly with a linear bore for containing the components of the assembly. The housing contains a connector component presenting a first taper portion. The connector is retained in the linear bore of the housing with a spring interposed between the connector and the housing. A tool containing a second taper portion is placed in axial engagement with the first taper causing the components to be securely connected. The spring limits the force applied between the taper portions allowing them to be disconnected easily.

Modular tool connection assembly

The cutter holder ( ) has, on the one hand, parallel fixed fingers ( ) equipped with a groove ( ) and, on the other hand, moving locking fingers ( ) of which the end ( ) is preferably conical. The milling cutter ( ) has at least one flat annular part pierced, on the one hand, with fixing holes and, on the other hand, with locking holes which are slightly angularly offset with respect to the locking fingers in a direction which is the opposite to the direction of rotation of the cutter. Once the cutter has been fitted over the fixed fingers and engaged in the grooves ( ), engaging the locking fingers in the locking holes has the effect of locking the cutter on the fixing fingers.

Milling cutter and cutter holder

Instrument holder comprising a shank (,) equipped with a head (,) designed to receive an instrument and a locking component (,) pushed against the head by a spring (,) bearing on a ring (,) sliding on the shank, and having means of connection (,) on the shank which is engaged by rotation of the ring, in such a way that the release of the ring allows the locking component, the spring and the ring to slide freely in order to permit cleaning of the instrument holder.

Instrument holder for surgical instrument

Surgical reamer consisting of a cutting head integral with a drive rod for driving it in rotation. The cutting head has, to the rear, auxiliary cutting teeth whose cutting edges are oriented alternately rightward and leftward in such a way as to permit easy withdrawal of the reamer, by the cutting effect of said teeth, in both directions of rotation.
