  • Publication number: 20160175112
    Abstract: A modular acetabular impactor and reamer system including a main body extending between a proximal handle end and a distal end. The system also includes a transmission rotatingly extending within the main body. The transmission has an accessory mount. The system also has at least one of an impactor handle and a reamer handle removably coupled to the main body proximal handle end. The impactor handle has a drive shaft to drive rotation relative to the impactor handle. The reamer handle has a drive mount to drive rotation relative to the reamer handle. The system also has at least one of an impactor cup and a reamer module removably coupled to the main body distal end. The transmission and the at least one of the impactor cup and the reamer module correspondingly rotate relative to the main body.

  • Patent number: 9187435
    Abstract: The invention relates to a method for preparing linear polymers having an amide end or having a star architecture comprising an amide core, by means of a ring opening using lactide and glycolide monomers or a lactide monomer ring in the presence of a catalyst, wherein the method includes the steps of: (i) reacting the excess monomer(s) with an initiator in a solvent, said initiator being selected from among an amine and an amino alcohol, given that the initiator has at least one primary or secondary amine function; (ii) adding a catalyst, said catalyst being a non-nucleophilic base and including at least one neutral sp2 nitrogen atom; and (iii) neutralizing the reaction mixture. Said novel method is particularly advantageous in that it can be easily monitored and enables better modulation of the polymers, and thus of the properties thereof, than the methods of the prior art. The invention also relates to novel polymers that are obtainable by means of said method.

  • Publication number: 20140276874
    Abstract: An acetabular cup impactor for surgery. The impactor has a handle, a bow arm and a prehension fastener secured to the bow arm opposite the handle. An elongated spine extends within the length of the bow arm between the handle and the prehension fastener. In use, the elongated spine rotates with respect to the bow arm and causes corresponding rotation of the prehension fastener with respect to the bow arm.
