    摘要: A bone fixation assembly (10) which includes a fixation plate (11) having a through passage (12) and a fastening screw (13) having a threaded shaft (14) for insertion through the passage (12) and thereafter threadable insertion into underlying bone. The screw head (15) has substantially frustospherical shaped side surfaces. A bushing (16) is provided and has an annular cup shaped side wall (17) defining an upwardly open interior bowl (20) for receiving the screw head (15). The bushing (16) has annularly shaped slots (21) in its side wall (17) which depend downwardly from its upper end (18) for allowing inward compression of the side wall (17) at the upper end (18). A centrally located screw shank passage (22) is provided in the lower end (19) of the bushing (16) to prevent passage of the screw shank (13). The bushing bowl (20) is further configured and dimensioned for polyaxial rotation of the screw head (15) in the bowl (20) and for preventing back out of the screw head (15) when the side wall (17) is compressed inwardly. The through passage (12) of the bone plate (11) is further configured and dimensioned to downwardly receive the bushing (16) therein for inwardly compressing the bushing (16) about the screw head (15) and an annular recess (23) is provided in the through passage (12) which receives the upper annular end (18) of the bushing (16) under compression with a snap fit whereby the screw head (15) is retained in the bowl (20) and is thereby prevented from backing out. The screw head (15) is expandable for thereby locking the screw (13) relative to the bone fixation plate (11).

    摘要: The invention relates to a device for joining a bone fixation element to a longitudinal rod. Said device comprises: A) a plate-shaped transversal connector (3) with a plate top side (5) for placing against a longitudinal rod (1) and with a cavity (7) that passes through said transversal connector (3); B) a clamping jaw (10), which can be resiliently compressed and which can be accommodated inside the cavity (7), and; C) a tightening means (12), which is provided for radially spreading the clamping jaw (10) inside the cavity (7), whereby; D) the transversal connector (3) comprises a boring (19), which passes through the transversal connector (3) from the plate top side (5) to the plate bottom side (6) and which is located at a distance (31) from the cavity (7). The inventive device also comprises: E) a longitudinal rod connector (13), which can be accommodated inside the boring (19) and which is provided with a channel (17) for accommodating a longitudinal rod (1), and; F) fixing means (33) for detachably fixing a longitudinal rod (1) that can be inserted into the channel (17), and for detachably fixing the longitudinal rod connector (13) with regard to the transversal connector (3), and such that; G) when the fixing means (33) is loosened, the transversal connector (3) is arranged in a manner that permits it to rotate with the longitudinal rod connector (13) about the central axis (14).

    摘要: The invention concerns a bone screw (14, 14', 14'') comprising a stem (22) defining a longitudinal axis (23), and a head (26) which can be locked into a part for receiving the bone screw (18) of a bone plate (12), to connect releasably the bone screw to the bone plate. The invention is characterized in that a safety element (28) is used for making secure the connection between the bone screw and the bone plate; the bone screw can shift from a locked position wherein the bone screw is maintained against the bone plate, to an unlocked position wherein the bone screw can be separated from the bone plate; the safety element can shift from an insecure position wherein the bone screw can be placed in the unlocked position, to a secure position enabling the connection between the bone screw and the bone plate to be secured, wherein the bone screw takes up the locked position. The invention aims at improving a bone screw of this type, such that a bone plate can be more easily and securely fixed to bone parts. Therefor, the safety element is mounted mobile on the bone screw.

    摘要: The invention relates to a device for the articulated connection of two bodies. Said device comprises A) a first body (1) which contains a hollow chamber (5) that is positioned coaxially in relation to a central axis (6); B) a clamping element (8) comprising a longitudinal axis (11) and a coaxial bore (15) with at least one opening (50) that adjoins said bore, whereby the clamping element (8) is configured in such a way that it can be elastically deformed in a complementary manner in relation to the hollow chamber (5) and perpendicular to the longitudinal axis (11); C) at least one tensioning element (12) which can be introduced into the opening (50) coaxially in relation to the longitudinal axis (11) and which can extend in an axial direction; D) a second body (2), which can be detachably connected to the first body (1) using the tensioning element(s) (12) and the clamping element (8); E) a drive element (19) which can be used to displace the tensioning element(s) (12) axially in relation to the opening (50), whereby F) the drive element (19) is connected axially to both the clamping element (8) and the tensioning element(s) (12) in a positive fit and in such a way that it can be rotated about the longitudinal axis (11).
