6 Claims, 8 Drawing Figures FLEX LIGHT BACKGROUND OF THE INVENTION 1. Field of the Invention A flexible surgical light comprising a housing configured to house a voltage source therein having an extended bulb assembly mounted on one end thereof and a switch means formed on the opposite end thereof, the switch means being movable to electrically couple and decouple the voltage source to the extended bulb assembly.
2. Description of the Prior Art A number of surgical lights have been developed for use in the medical profession and similar endeavors. Generally, these surgical lights comprise a current or voltage source in combination with a light source and switch means to actuate/deactuate the surgical light.
When used for surgical purposes, these lights often include extended flexible light assemblies to permit in sertion of the light into various body cavities for illumination thereof. In these configurations, the light source is commonly secured within a socket which is electrically coupled to the voltage source. Since the light source is simply screwed into the socket rather than securely affixed thereto as an integral unit, the light source may become dislodged from the socket during use and possibly fall into the patients body. This is obviously unacceptable particularly since the light source may remain undetected in the patients body.
Furthermore, the additional socket structure requires additional manufacturing and assembly costs.
Thus, there is a need for a relatively simple, efficient device comprising an integral light source/voltage source package that is both inexpensive to manufacture and assemble.
SUMMARY OF THE INVENTION This invention relates to a flexible surgical light. More specifically, the surgical light includes a tubular housing configured to house a voltage source in operative engagement with a light source mounted within an extended bulb assembly and a switch means operatively attached to the tubular housing to selectively actuate the surgical light.
The tubular housing comprises a hollow cylindrical barrel including retaining means formed at each end thereof to retain the extended bulb assembly and switch means therein. Disposed within the cylindrical barrel is a first conductor means extending substantially the length thereof. The first conductor means is arranged to operatively engage the extended bulb assembly and switch means as more fully described hereinafter while insulated from the voltage source.
The switch means comprises a switch base connected to the voltage source by a switch contact means formed thereon and a switch actuator means.
The extended bulb assembly comprises an elongated hollow sleeve having a mounting means attached to one end thereof and a bulb housing attached to the opposite end thereof, a light source mounted within the bulb housing, a second conductor means extending substantially the length of the hollow sleeve and a third conductor means within the second conductor means. The third conductor means comprises an insulated wire which extends through a semi-rigid metal tube which comprises the second conductor means. The second conductor means contacts the periphery of the bulb while the insulated wire is connected to the inner contact point of the bulb. At the base of the metal tube is a coupling means comprising a plastic collar surrounded by a metal ring which acts as a retainer for the bare end of the insulated wire which is bent backwardly over the plastic collar. The ring thus acts as a contact for the central core of the uppermost battery.
To operate, the operator rotates the switch actuator means from the first to the second position causing switch contact means to engage first conductor means to complete the circuit between the light source and the voltage source such that the current flows from the voltage source to the light source and returns through the first conductor means, switch contact means back to the voltage source.
By this unique combination of elements, a highly reliable relatively inexpensive surgical light is provided.
The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the invention will be indicated in the claims.

As best shown in FIG. 4, mounting means 38 comprises an enlarged base 60 and reduced upper portion 62 which cooperatively form ledge 64 therebetween such that ledge 64 and retaining lip 17 engage each other to secure extended bulb assembly 14 to barrel 11. As configured, extended bulb assembly 14 comprises an integral unit which prevents any accidental separation of parts during use.
As shown in FIGS. 3 and through 8, switch means 16 comprises switch actuator means 66 and switch base means 68. As shown in FIGS. 6 through 8, switch base means 68 comprises a hollow substantially cylindrical member 70 including retaining means 72 formed thereon to retain contact means 74 comprising a barlike member which extends outward from member 70.
