REMOTELY CONTROLLED APPARATUS AND SYSTEM FOR DETECTING AND LOCATING PHOTON EMISSIONS AND METHOD OF FABRICATION

The apparatus for detecting and locating a source of radiation includes a housing with a handle. A switch receiving channel is formed within the housing and has a switch contact surface and a load surface. One of the switch actuating surfaces is formed into the housing handle opposite the switch contact surface to define a predetermined switch wall thickness effective to inwardly transmit hand generated stress. A detector assembly is coupled to the housing and includes a crystal detector responsive to the emissions to provide corresponding detector outputs. A piezoelectric switch is actuable to provide switch signals and has a pressure responsive surface and an oppositely disposed support surface positioned within the switch receiving channel. The pressure responsive surface is located in abutting adjacency with the switch contact surface. A switch support assembly as two wedges exhibiting predetermined slopes and having respective mutually contacting abutting surfaces and first and s econd parallel outer surfaces spaced apart a loading distance derived by relative positioning between the abutting surfaces. A transmission assembly is coupled with the housing for conveying signals corresponding with the detector outputs and the switch signals to an evaluation and control system. Un instrumento de sonda que se forma teniendo un alojamiento unitario con superficies de funcionamiento del interruptor hundidas con el proposito de usarse para procedimientos quirurgicos emplea componentes de interruptor piezoelectrico dispuestos internamente dentro de un canal de recepcion del interruptor alargado y dispuesto internamente. El extremo delantero del instrumento de soporte a un cristal que contiene un montaje detector con un preamplificador y conductores asociados que se extienden dentro de un canal detector de senal separados del canal de recepcion del interruptor y protegidos del mismo por medio de una pared protectora. Los componentes piezoelectricos se mantienen adyacentes en asociacion precargada dispuestos hacia afuera de las superficies de funcionamiento del interruptor por medio de un montaje de soporte del interruptor de cuna doble. Se une permanentemente un cable alargado a un extremo trasero del componente de alojamiento a traves de la utilizacion de un sello de silicon de grado medico y de componentes de auxilio.
