Claims

[Claims for Utility Model Registration] (1) A focusing shaft is slidably inserted in the axial direction into the shaft hole of a guide shaft fixed to the rear opening of the reflecting mirror, and the rear end of the focusing shaft is inserted. A focus adjustment mechanism is constructed by threading an adjustment screw extending from the cap side into a screw hole threaded in the axial direction, and the focus adjustment shaft is adjusted by tightening or loosening the adjustment screw of the focus adjustment mechanism as appropriate. In the surgical light, which is configured to be able to move forward and backward in the direction of the inner axis of the guide shaft, and in which a light emitting body is attached to the tip of the focus adjustment shaft via a socket, the guide shaft and the focus adjustment shaft each have mutually connected side surfaces. a lead wire insertion hole that communicates with the guide shaft and opens at the rear end, and a terminal block that is fixed on the guide shaft is provided at the rear end of the guide shaft, and The end of the lead wire leading out from the socket and the end of the lead wire leading out from the support arm side which rotatably supports the reflector are fixed onto the terminal block with a fixing screw. A surgical light characterized by being configured to provide electrical continuity between lead wires. (2) The lead wire insertion hole opens a through hole that communicates with each other on the side surface of the guide shaft and the focus adjustment shaft, and also connects either or both of the through holes opened on the guide shaft and the focus adjustment shaft. The surgical light according to claim 1, characterized in that it is formed as a notched groove-shaped through hole opening at the end. (3) The terminal block straddles the guide shaft, has a so-called gate-like shape on the side, and has a reflector that can rotate freely as well as the end of the socket-side lead wire led out via the guide shaft. The end portion of the lead wire led out from the support arm side supported by the terminal block is fixed together with the terminal block using a fixing screw to obtain electrical continuity between the two lead wires. Shadowless light. (4) The terminal block has terminals fixedly arranged on the top surface of an insulating plate, and rotatably supports the end of the socket-side lead wire led out via the guide shaft, as well as a reflector. A surgical lamp characterized in that the end portions of the lead wires led out from the support arm side are each fixed onto the terminals using fixing screws to obtain electrical continuity between the two lead wires.
