A medical implant made of polymeric material having an increased oxidation resistance is formed by a method including the steps of placing a resin powder in a sealed container. A substantial portion of the oxygen is removed from the sealed contained by either a vacuum, an oxygen absorbent or by flushing with inert gas. The container is then repressurized with a gas such as nitrogen, argon, helium or neon so that long term storage may be possible. On use, the resin in transferred to a forming device which both melts and forms the resin in an oxygen reduced atmosphere to produce a polymeric raw material such as a rod or bar stock. The medical implant is then formed from this raw material annealed and sealed in an airtight package in an oxygen reduced atmosphere. The implant is then radiation sterilized and thereafter annealed in the package for a predetermined time and temperature sufficient to form cross-links between any free radicals in neighboring polymeric chains.

Height and length are adjustable at several points. There is a special type of vise for holding the gunstock. As usual, the vise bolt pulls the movable plate toward the fixed one but, like some of the vise's predecessors, traces out an arc at the top, pivoting from the bottom as the bolt, situated just above the pivot, is turned. Within the movable plate a special cylinder is situated which gives and turns freely in response to the bolt's advance and withdrawal in passing through a threaded tunnel within it. This action prevents the biting down or binding upon the bolt which would otherwise occur because of the plate's pivoted travel as the bolt is advanced or withdrawn. The support's framework, best made from economical tubular bar-stock, is adjustable for leveling and leaning corrections and include anchoring blocks within the structure through which leveling bolts pass.

In a side-pull hoist ring having a load carrying ring, a clevis pivotally supporting the load carrying ring for rotation about a first axis and a post assembly extending through the clevis and fixedly engageable with a threaded bore on a load for allowing 360 DEG rotation of the clevis about a second axis generally perpendicular to the load. The post assembly includes a lower support bushing with a large diameter lower load bearing flange and a bolt receiving passageway coaxial with the second axis; a bolt extending through the passageway into the threaded bore of the load where the bolt has a head carrying an upper flange member coacting with the lower flange to capture the clevis and a shank. There is a first cylinder groove in the passageway and a second cylindrical groove around the shank. The grooves are axially aligned when the lower flange and the upper flange capture the clevis. An arcuate spring element having a collapsed shape generally retained in the second groove and a relaxed shape bottomed out in the first groove and extending between the first and second grooves prevents non-destructive axial removal of the bolt from the bushing. The clevis is formed from extruded steel, bar stock or a steel plate.

A clamp is used to attach generally rectangular bar stock, such as existing Bookwalter / Codman rings, to a post in a surgical retractor system. The clamp interacts with corners of the ring at any of a wide range of widths and thicknesses, while still retaining a simple and intuitive tightening action such as through a rotational collar which absorbs some of the clamping force as a hoop stress.
