The invention concerns a bone fixing device (1) for immobilizing a linking rod (2) designed to connect at least one bone fragment (3) to another, said device comprising: at least one anchoring means (4) designed to be fixed on or in said bone fragment (3); at least one receiving part (7), secured to said anchoring means (4), designed to receive at least part of said linking rod (2); locking means (8) designed to lock said part of the linking rod (2) within said receiving part (7). The invention is characterized in that said locking means comprise at least one solid element (8) having a longitudinal axis, said solid element including at least one inclined surface (9) capable, under the action of a thrust directed along the longitudinal axis of said solid element, of gradually wedging by friction said part of the linking rod (2) into said receiving part (7), until said part of the linking rod (2) is completely locked inside said receiving part (7). The invention also concerns an assembly comprising such a device and a linking rod.

The invention relates to a capsule for closing a receptacle (R) for a liquid and for dispensing said liquid, said capsule being characterized in that it comprises: A capsule for closing a receptacle (R) for a liquid and for dispensing said liquid, said capsule being characterized in that it comprises: an inner support element (1) designed to be fixed on the neck (C) of the receptacle (R) and including a central bushing (11) having a side wall provided with an ejection orifice (10); and an outer closure element (2) that is fastened onto said inner element (1) and which includes a central ring (21) provided with an outlet duct (20), said central ring (21) being designed to surround said bushing (11) in coaxial and rotary manner so as to establish at least one closed position in which the ejection orifice (10) is sealed and at least one dispensing position in which said orifice is in communication with the outlet duct (20).
摘要:
The invention relates to an implant (1) for osseous fusion between two bones, including a first portion (20) having a longitudinal axis A, for being inserted in the first bone and including a first means (24) for attaching said implant in said first bone, and a second portion (30) having a longitudinal axis B, for being inserted in the second bone and including a second means (34) for attaching said implant in said second bone, said first and second portions (20, 30) being connected by a central core (40), said central core being a solid body, the cross-section of which, in a plane perpendicular to said longitudinal axis A, has the shape of a star having at least three points (41, 42, 43), said first portion having three tabs (21, 22, 23), each tab extending along said longitudinal axis A from the free end (41a, 42a, 43a) of one of the points of said central core.
摘要:
Pump for dispensing a dose of a fluid product, comprising a tubular body including an intake orifice; an end member associated with the body and including a rest abutment and an end-of-stroke abutment; a compression member mounted so as to move inside the body between a rest position in which said compression member is in abutment against the rest abutment, and an end-of-stroke position in which said compression member is in abutment against the end-of-stroke abutment, said compression member being elastically returned toward the rest position and including an exhaust orifice; a metering chamber; and an intake valve and an exhaust valve adapted to selectively close off the intake orifice and the exhaust orifice, respectively.
