Clamp (1) for an external fixator, preferably of the quick attachment type, comprising: a plurality of attachments (2; 3) for blocking bars and/or bone screws; a connector (5), provided with an at least partially threaded stem (50), which passes through and connects in series said plurality of attachments (2; 3); at least one first attachment (2) comprising two arms (20; 21), connected by a C-shaped flexible bridge (22); said stem (50) passing through said first attachment (2) in an intermediate position between said flexible bridge (22) and the opposite free ends of said arms (20; 21); wherein, at the free ends, said arms (20; 21) define a screw housing seat (23) for a bone screw, said screw housing seat being selectively configurable, varying the deformation of the flexible bridge (22), to clamp bone screws having different diameter.
Clamp (1) for an external fixator (100), comprising:
Clamp (1) according to one of the preceding claims, wherein at least one of said arms (20;
Clamp (1) according to one of the preceding claims, wherein said screw housing seat (23) is defined by specular V-shaped profiles, which are facing and opposite one another, of respective jaws (27a;
Clamp (1) according to one of the preceding claims, wherein said first attachment (2) also provides for a bar housing seat (26) for a bar (101) of the external fixator (100).
Clamp (1) according to one of the preceding claims, wherein said connector (5) provides, at an end of the stem (50), for a coupling profile (53) for a tightening tool and a tightening knob (54), with a diameter substantially greater with respect to said coupling profile (52), for the manual tightening of the connector (5).
Clamp (1) according to one of the preceding claims, further comprising a second attachment (3) provided with a bar housing seat (36) or a third attachment (4) provided with one or more screw housing seats (42;
