Light source apparatus for endoscope

Abstract

Abstract An endoscope light source device comprises a light source device body (6) and a connector receptacle (7) rotatably set therein. The connector receptacle (7) is provided with a central through hole (28) for receiving a light guide (10) and cylindrical holes (29) penetrated by contact pins (13) projecting from a base (9) of the connector receptacle (7). The control pins (13) are connected to the leads (30) extending through the connector receptacle (7). The leads (30) are connected to signal lines (33) coupled to the signal-generating circuit provided in the light source device body (6). An electric connection mechanism is mounted on the signal lines (33) or provided between the respective signal lines (33) and leads (30) to ensure electric connection between the signal lines (33) and leads (30). An air-conducting passage is provided in a connection conduit (34,35) formed in the connector receptacle (7) for communication with the air conducting connection tubes (14,15). A fluid-conducting mechanism is provided between the air-conducting-connection tubes (14, 15) and air-conducting passage to ensure communication therebetween, regardless of the rotated position of the connector receptacle (7). Provision of the rotatable connector receptacle (7), electric connection mechanism and fluid-conducting mechanism eliminates the necessity of removing the connector from the endoscope body (1) for each rotation of the endoscope in order to relieve the endoscope from torsion.
