A surgical bone milling instrument, suited to operate in a hole formed in a bone, comprising a milling element (10), with longitudinal axis (A) and with the forward end portion (11) rotating around a longitudinal axis (A), and milling the bone. The instrument comprises a tubular element (30) of circular external cross-section and provided with a thread engaging, by helical coupling, a hole formed in the bone. The milling element (10) is associated with the tubular element (30), arranged so that the forward end portion (11) thereof is located ahead of the tubular element (30) and can rotate around the longitudinal axis (A) thereof and translate axially relative to the tubular element (30). The milling element (10) has a rear portion (14) which passes coaxially through the tubular element (30), while the forward end portion (11) projects beyond the front of the tubular element (30). The milling procedure of a bone cavity can be completed while maintaining control of the position of the device relative to the hole. Furthermore, in each phase in which the milling element is rotated, while the instrument is axially stationary inside the hole, a groove is created on the end of the hole (or an extension of the entire hole) the depth of which is constant and predetermined. Further, by way of axial pressure applied to the milling head by the drive element, a detachment of residual bone wall can be achieved as soon as this has reached a breaking resistance which is lower than a force applied by the drive element.

Method to attach two sections of bone together in which a telescoping screw system is positioned through a hole of a fixation device attached to a first section of bone while the screw system is in a closed configuration in which the screw body is telescoped inside the screw barrel. The screw body is then advanced relative to the screw barrel to cause penetration of the forward, threaded end of the screw body into a second section of bone, and thereby bring the screw system toward an open configuration in which the screw body is telescoped outside the screw barrel. The screw barrel is also engaged to the fixation device via a cooperating engagement mechanism.

A bone resector tool (100) comprises an ultrasonic transducer (8), typically generating longitudinal mode vibrations at around 40 kHz, and having an elongate blade portion (2) mounted thereto. The transducer (8) and blade portion (2) are mounted to a rotatably- drivable converter element (3). Rotation of the converter element (3) produces reciprocal longitudinal motion of the transducer (8) and blade portion (2). A counterweight (5B) is also mounted to the converter element (3), moving exactly out of phase with the transducer (8) and blade portion (2), such that a centre of mass of the whole system is stationary, reducing vibration of the tool (100) in a user's hand. The peak velocity due to the ultrasonic vibrations of a distal tip (6A) of the blade portion (2) is up to seven times greater than its peak velocity due to the reciprocal longitudinal motion. This permits rapid, low-effort cutting of bone with easy removal of cut debris and minimal consequent necrosis.
