Definitions

  • a joint swiveling device of the individual projectors operable from outside, with which the distance between the lamp housing and the spot at which the optical axes of the individual projectors meet is adjustable.
  • An adjusting support for the reversals of the lamp protrudes, in the form ofa lateral bearing, serving for the suspension of the lamp and adjustable by turning it at that spot.
  • the turning is transmitted through the adjusting support to a toothed rim by means of a pinion disposed towards the central lamp, a steering rod gearing also articularly to the proper swiveling individual projector or to the circularly curved guide rail of an adjustable individual projector. Since, due to the overlength of the rods, these do not run radially and on the symmetrical axis of the surgical operating lamp, a radial displacement component is transmitted to the individual projectors by the turning of the pinion, whereby these change their position jointly and evenly, so that the point of intersection of the optical axes n the symmetrical axis of the surgical operating lamp can be shifted.
  • the object of the invention consists in the creation of a surgical operating lamp of the mentioned type, without a central light, whereby the individual spotlights can be completely linearly shifted and adjusted, at least in the main area, in a simple manner and are easily accessible.
  • the surgical operating lamp should be simple in design, and therefore inexpensive, and contain only a few component parts needing no servicing. Furthermore, the arrangement should be so selected that the operating lamp is as compact as possible, in order to oppose as little a resistance as possible in the operating theatre or in an operating cabin to an air current serv ing as sterilizer and directed from top to bottom, paral lel to the lighting circuit.
  • each individual lamp assembly is pivotally attached to the surgical lamp structure and has a pin extending from one side which engages a central slotted cam member which is rotatable from below the lamp.
  • the most important advantage of the invention is that it makes it possible to attain a completely linear shifting and adjustment of the individual lights by turning in a simple manner the slotted cam member disposed in the center of the lamp and accessible from be low.
  • the whole surgical operating lamp is uncomplicated and inexpensive in construction, and allows a compact arrangement of the individual lights.
  • the new surgical operating lamp can be constructed considerably smaller, so that the sterilizing air current is only slightly impaired. Since the slotted cam member can be directly rotated from below, it can also serve to adjust the whole surgical operating lamp in its suspension.
  • FIG. 1 shows a sectional view of a surgical operating lamp according to the present invention.
  • FIG. 2 shows a sectional view of the surgical operating lamp of FIG. I.
  • a surgical operating lamp 10 has a housing 12 closed towards the top, at the lower side of which windows 14 are disposed in the area of each individual lights 16.
  • Each individual light 16 houses a bulb 20 disposed in a lamp spot-light 18.
  • Each of the individual lights 16 are pivotally attached to mounts 22 attached to the lower portion of housing 12. The pivoting axis of each light is tangent to a common circle around the central axis of the surgical operating lamp 10.
  • Each individual projector 16 is also provided with a pin 24 which is dis posed at the spot nearest to the central axis of the surgical operating lamp 10. The pin 24 engages slot 28, in a slotted cam member 26, disposed centrally and revolvable from below by way of handle 30.
  • the slotted cam member 26 is formed with interme diate wall 26a, upper wall 26b having a plurality of cam slots 28 therethrough and lower wall 260 to which is attached handle 30.
  • the number of cam slots 28 corre' spond to the number of individual lights l6 used in the operating lamp.
  • Lower wall 266 of slotted cam 26 is projected to the outside of the lamp through an opening at the lower side of the surgical operating lamp.
  • Handle 30 is attached to lower wall 26c such that it transmits torque to the cam member 26, but may be removed therefrom to facilitate sterilization.
  • the slotted cam 26 is prevented from inadvertent rotation by spring 32, which frictionally bears against in termediate wall 26a and adjustable stop 36.
  • the position of stop 36 relative to cam member 26 is variable by screw connection on a bolt 34.
  • the surgical operating lamp 10 is suspended from rod 38 by means of known type which permit angular adjustment of the lamp assembly.
  • a surgical operating lamp with three individual lights 16 is used, said lights being disposed at 120 from each other around a starshaped lighting body.
  • the housing 12 encloses the individual projectors l6 and is indented between them, so that the area of the surgical operating lamp l0 hereby submitted to the sterilizing air current is relatively small.
  • the surgical operating lamp can also have any amount of individual lights 17 and, in such case a circular housing 12 may be used.
  • the adjusting handle can be connected to lower wall 26c to transmit torque therebetween and still be released for sterilizing purposes of the surgical operating lamp.
  • the central adjusting handle 30 serves, on the one hand, for the swiveling and adjustment of the whole surgical lamp 10 with respect to support 38, and, on the other hand, for the focusing of the individual projectors l6. lts central position enables an easy access in each position of the surgical operating lamp 10.
  • the main advantage of the new surgical operating lamp consists in that the shifting and adjustment of the individual projectors, and thus, the focusing, can be attained completely linearly and with a compact construction of the surgical operating lamp, with less and simpler means than with the known surgical operating lamp. Thereby the adjustment of the inclination of the individual lights occurs over a joint and central adjusting handle of easy access and which is easily removable and can be rapidly sterilized in case of need.
  • a surgical operating lamp having a housing with at least one hole therethrough and a plurality of individual lights pivotally mounted within said housing and disposed about a central axis of the lamp such that the rays of each individual light meet on the central axis at a desired distance from the lamp
  • the improved lamp pivoting means comprising a.
  • cam means within the housing having an annular intermediate wall oriented perpendicular to the central axis of the lamp, an upper wall attached to the outer periphery of said annular intermediate wall and extending in a first direction, said upper wall having a plurality of slots therethrough defining a plurality of cam surfaces, the longitudinal axes of said slots inclined with respect to the central axis of said lamp, and a lower wall attached to the inner periphery of said annular intermediate wall and extending in a direction opposite that of said upper wall, said lower wall pivotally extending through the hole in said lamp housing;
  • said frictional anti-rotation means comprises a spring having one end bearing against said cam means and the opposite end bearing against adjustable stop means threadingly engaged with a bolt projecting through the top of said housing.
