摘要：
A surgical device (1) comprising a polyaxial surgical screw (100) comprising an internally hollow tulip (101) having a first open end (103) for accessing the interior of the tulip (101), a second end (104) opposite to the first end (103), and a side wall (102) developing between the first and second ends (103, 104). The tulip (101) comprises two elongated rods (110) which are parallel and mutually spaced apart, each elongated rod (110) protruding from the side wall (102) and extending away from the first end (103) of the tulip (101) in a direction opposite to the second end (104) of the tulip (101). The rods (110) define a channel (111) in communication with the first end (103) for accessing the interior of the tulip (101). The screw (100) further comprises a threaded shaft (106) having a first end (107) defining the screw tip and a second end (108) opposite to the first end (107) having a ball joint (109) associated with the second end (104) of the tulip (101) to orient the shaft (106) with respect to the tulip (101) itself. The surgical device (1) comprises a locking unit (2) which can be reversibly mounted on the polyaxial surgical screw (100). The locking unit (2) comprises a tubular body (3) which has an inner cavity (4) and is adapted to be fitted about the elongated rods (110) during a configuration of use of the surgical device (1). The tubular body has two mutually opposite protrusions (5) which project into the inner cavity (4). The protrusions are configured to face the channel (111) defined between the rods (110) and be mutually interposed to prevent the mutual removal and approach during the configuration of use of the surgical device (1).L'invention concerne un dispositif chirurgical (1) comprenant une vis chirurgicale polyaxiale (100) comprenant une tulipe intérieurement creuse (101) ayant une première extrémité ouverte (103) pour accéder à l'intérieur de la tulipe (101), une seconde extrémité (104) opposée à la première extrémité (103), et une paroi
