Apparatus for positioning the lower limb of a patient during operation, in particular for hip replacement operations with anterior approach, and surgical positioning system comprising said apparatus

摘要

Apparatus (20') for positioning the lower limb of a patient (500) during operation, in particular for hip replacement operations with anterior approach, comprising: a traction arm (30') with at least a distal portion (34', 36') defining a traction axis (x'); a support framework (40') coupled to said traction arm (30') so as to allow the adjustment of the position of one of its distal ends (32'); a coupling (60') constrained to said traction arm (30') and arranged to be associated to the distal end of the lower limb of the patient (500); at least a first actuator (34') which defines with its action a relative movement of the coupling (60') with respect to the traction arm (30'), at least a component of said relative movement being parallel to the traction axis (x').
