Abstract:
1. A driving apparatus for a surgical instrument suitable for being connected to the driving apparatus by a driven shaft, in turn suitable for being driven by a drive shaft, comprising: driver elements for driving the surgical instrument by the drive shaft; power supply elements for the driver elements; control elements for the driver elements; a casing suitable for containing the driver elements, the power supply elements and the control elements and which comprises an ergonomic grip for manipulating the appliance, the control elements being integrated in a wall of the casing, an interconnection device of the drive shaft and the driven shaft, with a proximal end and a distal end; isolation elements between the drive shaft and driven shaft and, at least partially, of the interconnection device between these two shafts, which prevent any direct contact between the drive shaft and the driven shaft, so as to prevent the propagation of accidental contamination from the drive shaft to the driven shaft and to the surgical instrument; wherein the casing is suitable for being sterilised before inserting in it the driver elements, the power supply elements and the control elements, and wherein such casing is removable and interchangeable, and wherein: the isolation elements comprise a chamber impermeable to pathogens, said chamber defining an inner space, through cooperation of a proximal transversal wall, a distal transversal wall and an axial wall, which is arranged at least partially around the interconnection device and which comprises a proximal ring and a distal ring ensuring sealing, respectively, of a proximal axial opening and a distal axial opening arranged, respectively, in the proximal transversal wall and in the distal transversal wall of the chamber.
