1. Device ( 10 ) for manual control of a surgical guide (G), comprising a body ( 12 ) provided with a conduit ( 14 ) for passage of the surgical guide (G), and a member ( 16 ) for axially immobilizing the surgical guide relative to the body, which member ( 16 ) comprises a conduit ( 50 ) for receiving the surgical guide and is displaceable between a position in which it immobilizes the surgical guide and in which the conduits ( 14 , 50 ) formed in the body ( 12 ) and in the immobilizing member ( 16 ) are not aligned, and a position in which it releases the surgical guide and in which the conduits ( 14 , 50 ) formed in the body ( 12 ) and in the immobilizing member ( 16 ) are aligned, the device comprising means ( 44 ) for elastic return of the immobilizing member ( 16 ) to its immobilizing position, characterized in that:

said immobilizing member ( 16 ) is made integral in one piece with the body ( 12 );

said body ( 12 ) comprises a seat ( 28 ) for receiving the immobilizing member ( 16 ) in the immobilizing position, which seat ( 28 ) forms an interruption of the body conduit ( 14 ), which body conduit ( 14 ) delimits, on each side of the seat ( 28 ), two spans ( 62 , 64 ) for transverse support of the surgical guide (G);

at rest, the immobilizing member ( 16 ) is outside the seat ( 28 ) provided for receiving the immobilizing member;

said device comprises an arm ( 18 ) bearing said immobilizing member ( 16 ), which arm ( 18 ) is articulated relative to the body ( 12 ); and

the arm ( 18 ) bearing the immobilizing member is connected to the body ( 12 ) via an elastically deformable connecting region ( 44 ) constituting said means for elastic return of the immobilizing member ( 16 ) to its immobilizing position.
