Title: Innovations of John D Call
Introduction
John D Call is a notable inventor based in Columbus, OH (US). He has made significant contributions to the field of surgical technology, holding a total of four patents. His work focuses on the development of advanced surgical probe apparatuses that enhance medical procedures.
Latest Patents
One of his latest patents is a surgical probe apparatus that incorporates a probe structure with a handle component and a forward crystal mount. This design features a cadmium-telluride crystal that is rigidly mounted to prevent movement. Additionally, a cup-shaped window assembly is included, which has an internal cylindrical tungsten shield extending from the front face of the crystal. This assembly defines an air gap and supports an aluminum window. The window assembly is threadably mounted on the handle at a transition region, forming an outwardly extending ramp. This ramp works in conjunction with a polymeric retainer component that holds a cylindrical tungsten collimator in a biased position against the window when attached.
Another significant patent is a surgical system that features a two-component hand-held probe. This probe includes a sterilizable and reusable detector portion made primarily of metal, along with a disposable handle and cable combination. The detector assembly contains a crystal receiver that retains a detector crystal in compression by an annular metal ring assembly. This assembly has thin inwardly depending tines that contact the crystal's forward surface and apply electrical ground. An access channel supports bias and signal-carrying electrical leads through a crystal mount to the rearward face, which also supports the forward stage of a preamplifier.
