The invention relates to forceps (1) for grasping bones or bone fragments comprising two forcep levers (2; 3) which can pivot in relation to one another. Said forcep levers have clamping tips (7; 8) which are located on the ends (9; 10) of the forcep levers (2; 3) appointed for grasping a bone. The forceps (1) also comprise a fixing means (6) for fixing the relative distance of the forcep levers (2; 3) from one another in a manner which can be loosened. The forceps have a connecting pin (11) with which another element can be connected inside a repositioning device. The fixing means (6) is arranged at a distance y from the axis of rotation (5), and the longitudinal axis (12) of the connecting pin (11) lies in the pivoting plane of the forcep levers (2; 3). The device for the external fixation of bone fractures comprises at least one pair of repositioning forceps (1) and one longitudinal support. The device also comprises at least one clamping element (19) which detachably connects the connecting pin (11) of the repositioning forceps (1) and the at least one longitudinal support (18) such that they can rotate in relation to one another.
L'invention concerne une pince (1) permettant de saisir les os ou les fragments d'os. Cette pince comprend deux leviers (2; 3) pouvant pivoter l'un en direction de l'autre et deux pointes de serrage (7; 8) placées aux extrémités (9; 10) des leviers (2; 3) servant à saisir l'os. La pince (1) comprend en outre des moyens (6) de verrouillage permettant de bloquer de manière réversible la position relative des leviers (2; 3) de pince l'un par rapport à l'autre, ainsi qu'une cheville (11) de liaison permettant l'assemblage de la pince avec un autre élément faisant partie d'un dispositif de réduction. Les moyens (6) de verrouillage se trouvent à une distance y de l'axe (5) de rotation et l'axe (12) longitudinal de la cheville (11) de jonction est situé dans le plan de pivotement des leviers (2; 3). L'invention concerne également un dispositif permettant une fixation externe des fractures osseuses et comprenant au moins une pince (1) de réduction et une tige de support ainsi qu'au moins un élément (19) de serrage permettant d'assembler de façon amovible la cheville (11) de liaison de la pince (1) à réduction et la tige (18) de support, une rotation relative étant assurée entre les deux.
