摘要：
Apparatus (20； 20 ') for positioning the lower limb of a patient (500) during an operation, comprising: at least a distal part (34, 36； 34', 36 ') of a traction arm (30； 30 '), which may be confined to an integral connecting element (6； 6') with a surgical table (100) so that it defines an axis (x； x ') for traction of the patient's lower limb (500)； a support frame (40； 40 ') coupled with said distal part (34, 36； 34', 36 ') so as to allow adjustment of the position of a distal end (32； 32') thereof； a coupling (60； 60 ') confined to said traction period (30； 30') and arranged to be associated with the distal end of the patient's lower limb (500)； at least a first actuator (34； 34 ') which defines with its action a relative movement of the coupling (60； 60') with respect to the traction arm (30； 30 '), being at least one component of said parallel relative movement to the traction axis (x； x '), wherein said coupling (60； 60') is supported by a first slide (35； 35 ') slidable along the traction arm (30； 30'), determining said first actuator (34； 34 ') the sliding of the first movable slide (35； 35') along the traction arm (30； 30 '), wherein said support frame (40； 40') comprises a post (42； 42 ') to which a second movable slide (45； 45') is slidably confined, said distal end (32； 32 ') of the traction arm (30； 30') being articulated with said second slide ( 45； 45 '), a second actuator (44； 44') being provided to determine the movement of the second slide (45； 45 ') along said upright (42； 42')； wherein the support frame (40； 40 ') comprises a carriage equipped with wheels (41； 41') with fixed wheels oriented in directions parallel to each other； said support frame (40； 40 ') further comprising at least one support wheel (46') which may be directed in the offset direction with respect to the fixed wheels； providing means for blocking said slides (35； 35 '； 45； 45') configured to automatically block said slides (35； 35 '； 45； 45') at the end of the movement establi
