Abstract: A patient limb positioning apparatus comprises a movement assembly operating on a coupling bracket which can be engaged with the patient's limb, to move the limb according to a plurality of axes of movement. The movement assembly comprises, for at least one of said axes of movement, a drive unit which can be activated to move the coupling bracket according to a predetermined direction of movement. A load transducer detects a load transmitted between the coupling bracket and the drive unit in the respective direction of movement, to emit a signal representative of a detected load value. An electronic control unit is selectively switchable to a load control command mode and is suitable to cyclically compare the measured load value with a pre-set load value, to control activation of the drive when the detected load value differs from the pre-set load value.

Abstract: Various implementations include a guide for intramedullary reamer; that includes a central body adapted to be received in a medullary canal and defining an inlet opening and an outlet opening, communicating with each other by an axial cavity, passing inside the central body, adapted to receive a reamer inside it. The central body defines at least one non-rectilinear portion, interposed between the inlet opening and the outlet opening, shaped so as to guide the reamer inside the medullary canal, in axial alignment. The non-rectilinear portion defines a window adapted to facilitate the insertion of the reamer inside said central body.

Abstract: Disclosed is a guide for intramedullary reamer, including: a central body adapted to be received in a medullary canal and presenting an inlet opening and an outlet opening, communicating with each other by an axial cavity, passing inside the central body, adapted to receive a reamer inside it; said central body presenting at least one non-rectilinear portion, interposed between the inlet opening and the outlet opening, shaped so as to guide the reamer inside the medullary canal, in axial alignment, wherein said non-rectilinear portion presents a window adapted to facilitate the insertion of the reamer inside said central body. Other aspects are described and claimed.

Abstract: A system to facilitate surgical operations by optimally positioning limbs of patients lying on a surgery table. The system comprises a surgery table and a converter. The converter comprises five sub-systems with varying degrees of freedom.

Abstract: A system to perform, under optimal conditions, surgical operations on limbs of human bodies lying on bases to extend the patient, comprising a surgery table and a converter, the converter including at least five sub-systems with different liberty degrees of movement.
