Abstract: The present disclosure relates to an osteosynthesis device comprising, on the one hand, a plate (12), which can be adjusted along a bone element (10), and at least one pin (26), and, on the other hand, a locking bushing (30) for rigidly connecting said plate (12) and said at least one pin (26). Said locking bushing (30) has a screwable part (32) and a drive part (34) separated from each other by a breakable zone (38), said screwable part having axial slits (44) that form notches (50). Said breakable zone (38) is intended to be broken in order to free said screwable zone (32) from said drive part (34). Said axial slits (44) extend into said breakable zone (38) so as to be able to fragment said screwable part (32) into independent notches (50) when said breakable zone (38) is broken, in order to be able to adjust the relative position of said notches (50) around said at least one pin (26).

Abstract: The invention relates to a locking ring (20) for a threaded holding pin (18) to be screwed into a part of a bone (14), said ring including a first portion (22) having an axial bore (24) for receiving said holding pin, the periphery of said first portion being threaded so as to interact with a holding plate (12), wherein said ring in characterized in that the same further comprises, as an extension to said first portion, a second portion (28), said second portion being deformable and thus capable of blocking said ring on said pin by deformation.

Abstract: The invention relates to an osteosynthesis device having a plate (10) which includes a recess (12) which defines an inner edge (22) and receives a ring (14) designed to receive the pin (20). According to the invention, the plate (10) has a threaded opening (26) on the edge of the recess (12), which 25 opens into the inner edge (22), while the ring (14) is slit radially. The device includes a screw (32) that can be screwed through the threaded opening (26) so as to bear against the ring (14) and cause the ring (14) to bear with force against a portion of the inner edge (22) and tighten the ring (14) on the pin (20).

Abstract: A surgical apparatus for osteosynthesis, includes a plate (2) provided with at least two holes and intended to join two bone parts, and a blocking sleeve (10) which is substantially of revolution and is intended to be screwed into one of the holes of the plate, the blocking sleeve having an axial orifice for passage of a pin to be screwed into one of the bone parts, wherein the lower part of the blocking sleeve has a slit along at least one of its radii, and the blocking sleeve and the associated hole cooperate by threaded engagement in order to block the sleeve in the hole when the sleeve is screwed into the hole.

Abstract: The invention relates to an osteosynthesis device comprising a plate (10) and means for fixing a pin (20) that extends through the plate, in which the plate (10) includes a recess (12) for receiving the fixing means and the recess defines an inner edge (22), said fixing means comprising a ring (14) designed to received the pin (20) and screwable locking means (32). According to the invention, the plate (10) has a threaded opening (26) on the edge of the recess (12), which opens into the inner edge (22), while the ring (14) is slit radially. The screwable locking means comprise a screw (32) that can be screwed through the threaded opening (26) so as to bear against the ring (14) and cause the ring (14) to bear with force against a portion of the inner edge (22) and tighten the ring (14) on the pin (20).

Abstract: A device which is used to immobilize a threaded support pin (21) in relation to a fixed element (1, 34), the pin being screwed into a bone part (3, 3a, 3b) along an axis. A locking sleeve (13) can be solidly screwed to the fixed element (1, 34, 7) and is provided with an axial bore (19) in order to receive the pin (21). The axis (zz?) of the sleeve screw thread is angularly and/or laterally offset in relation to the axis (yy?) of the pin (21) when the latter is in place on the bone part (3, 3a, 3b), and/or the axis of the bore (19) of the locking sleeve (13) is angularly and/or laterally offset in relation to the screw threaded axis (6).

Abstract: An osteosynthesis ring for maintaining one or more fractured bones in compression, the ring being used in combination with a pin, includes a hollow cylindrical body. The body is made of an elastic biocompatible material. The body has a channel extending therethrough along an axis of revolution of the body for receiving a pin. The body is structured for blocking at least one of translation and rotation of the body. A proximal part of the body includes a slot along at least one diameter of the body, the slot defining at least two separate parts, the at least two separate parts being adapted to spread apart from one another.

Abstract: Device for pinpointing lesions detected in a breast comprisingan anchoring means comprising one or more flexible and elastic elements which are capable of assuming a linear form during positioning and of deforming once in place, andat least one wire of a length which is at least equal to a depth of implantation of the anchoring means within the breast.

Abstract: A device for the holding and compression of the fragments of a fractured bone, the device including a screw whose tip is pyramidal or conical and whose body is provided, at a distal end thereof, with an outside thread, wherein the head of the screw has a plurality of foldable small wings integral with the body and wherein the screw has a device for folding the small wings. The device is useful particularly for fractures of the scaphoid, of the medial malleolus, Garden fractures 1 and 2 of the neck of the femur, pertrochanterian fractures of the femur, and generally, for fractures of small bones, and for putting in place hip or shoulder stops.
