摘要： PROBLEM TO BE SOLVED: To provide a method for producing a wear resistant polyethylene medical implant.SOLUTION: The method includes: a step of forming a medical implant made at least partially of ultra high molecular weight polythylene (UHMWPE) such as an orthopedic implant. The polyethylene may be irradiated with gamma ray or e-beam radiation to form free radicals and then crosslinked to eliminate the free radicals prior to exposure to oxygen. The so treated bearing surface of the crosslinked polyethylene is then coated with a photoinitiator. Thereafter the bearing material is photocrosslinked with ultra-violet (UV) radiation. The hotocrosslinking process can also be applied to non-crosslink UHMWPE.

摘要： PROBLEM TO BE SOLVED: To provide an implant which is manufactured from a polymer like a hydrogel containing a radiation visible substance therein and can replace an original nucleus obtained when cutting off an intervertebral disk. SOLUTION: It is preferable that the material for the implant is a powder type distributed in the whole of a polymer or a powder type distributed in another peculiar position in a layer or a polymer. A radiation non-penetrating substance is a metal, for instance, gold, tungsten, titanium, tantalum, or platinum. It is also preferable that the metal is a foil or wire type positioned in the hydrogel such as polyurethane to thereby make the implant X-ray visible. Other than the hydrogel, another polymer can also be used by distributing a radiation non-penetrating substance therein. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide a porous scaffold having desired characteristics such as high porosity, pore size and high strength, and to provide an implantable medical device, especially an orthopedic implant, comprising the porous scaffold. SOLUTION: The porous metallic scaffold comprises a porous network structure having pores defined by metal honeycomb walls. The metal honeycomb walls are coated with at least one layer of metal particles that are bonded to the walls. In particular, a skin of biocompatible metal is formed on a polymer foam by low temperature arc vapor deposition, the polymer foam and the metal skin are heated above the decomposition temperature of the polymer foam in an inert gas atmosphere, and the polymer foam is decomposed to obtain an unsintered metal foam. The unsintered metal foam is then coated with a bond solution, is sintered to thicken the thickness of the metal foam, and a final metal foam having a predetermined pore size is obtained.

摘要： Techniques are described for identifying bone areas for removal during a medical procedure. Processing circuitry may generate a virtual model of an anatomical object with the bone areas removed and one or more indications for the bone areas that are to be removed. During surgery, the processing circuitry may receive image data and update the one or more indications as the bone areas are removed. The processing circuitry may generate the virtual model and the bone areas for visual overlay on the actual anatomical object.

摘要： A glenosphere handling tool is provided that includes an elongate body and a retention portion. The retention portion is disposed at a distal end of the elongate body. The retention portion includes a plurality of wall segments of the elongate body separated from each other by one or more slots. The slot(s) extends proximally from the distal end of the elongate body. The retention portion includes an enlarged periphery at the distal end of the elongate body. The enlarged periphery comprising a proximally facing edge configured to engage an inner wall surface of a glenosphere. The retention portion is configured such that when the retention portion is in a free state the proximally facing edge faces and may contact a surface of a glenosphere to retain the glenosphere. The retention portion is configured to be deflected at the distal end of the elongate body such that the enlarged periphery has a reduced profile for separating the handling tool from a glenosphere.

摘要： In some examples, a simulator system may simulate one or more minimally invasive surgery (MIS) procedures associated with bone removal. The simulator system comprises an input device configured to detect a position of a portion of a user tool relative to an operation envelope, a simulation device defining one or more surfaces that define one or more boundaries for a movement of the user tool relative to the operation envelope during a simulated surgical procedure, and processing circuitry. The processing circuitry is configured to receive, from the input device, information indicative of the position of at least the portion of the user tool relative to the operational envelope, generate a performance metric based on the position of at least the portion of the user tool relative to the operational envelope over a period of time, and output, for display to a user, the performance metric.
