Definitions
- Another object is to provide a light that is simple in construction, economical to manufacture, and simple and efficient to use.
- Another object of the invention is to provide a compact high intensity light that may be positioned with minimum obstruction close to the operating site.
- Another object is to provide a high intensity surgical light wherein the parts thereof can be sterilized, and therefor handled by the surgeon to directly adjust the light.
- Another object is to provide a surgical light and cooling means combination.
- FIG. I is a view of the light according to the invention in use with a surgical table.
- FIG. 2 is a view of another embodiment of the surgical light and a stand.
- FIG. 3 is a cross-sectional view taken on line 3-3 of FIG. 1.
- FIG. 4 is a transverse view taken on line 4-4 of FIG. 3.
- a light head 10 is shown supported on an extension are 12 attached to a cooling means 17 which may include a blower or the like.
- the light head 10 is supported above the surgical table 18, which shows a patient 19 supported thereon at the operating site.
- the light head 10 is made up of the housing 29 which is threadably attached to the light support conduit 28 at 30.
- the conduit 28 is attached to the housing to the cooling means 17 in a similar manner.
- the housing 29 has a generally cylindrical outer surface over which the adjusting cylinder 20 is telescopically disposed.
- the adjusting cylinder 20 has two O-ring grooves therein which receive the O-rings 21. These O-rings make sealing engagement with the outer periphery of the housing 29.
- the filter I may be of a type to filter out the undesirable wavelengths of light from the high intensity lamp l3 and a lens 16 is supported outward of the filter l5 and held in place by a snap washer 31 which holds the lens against the ring spacer 32.
- the air conduit 27 is threadably attached to the reflector 14 at 33 and the reflector 14 has an opening therein that receives the grommet 24 through which the electrical wire 23 passes, which attaches to the light socket 25.
- the engagement 29 and reflector 14 could be attached to the conduit 28 and the said conduit 27 in any suitable manner other than threading.
- the socket 25 is held in place by the support 26 having openings therein to allow the passage of air therethrough.
- the reflector 14 is supported on the housing 29 by means of a spider 34.
- the cooling means which may be a blower indicated at 17 shown supported on a wall which may be the ceiling 40, will circulate air through the air conduit 27 down over the bulb 13, in the direction of the arrows and into engagement with the filter 15. The direction of air will then reverse and flow back up through the space between the air conduit 27 and the light support conduit 28 to a space outside the operating room, thereby carrying away heat from the lamp 13.
- a surgical table 118 supporting a patient 119, at the operating site, with a light head 110 similar to the light head I0, surgical table 18 and the patient 19 shown in the embodiment in FIG. 1.
- the light head is supported by the extension am 112 on the stand 111.
- a cooling means 117 is provided to circulate air through the light head 110 in the same manner as indicated in detail in FIG. 3.
- the adjusting cylinder 20, or the entire head may be removed from the housing 29 so that it may be sterilized and thus not contaminate the hand of a person who may adjust it during an operation. It will further be noted that no cooling air passes over the lamp l3. ever comes into engagement with the operating area. To the contrary, the air is drawn from outside the room or from outside the operating area over the lamp bulb and is discharged into the same area from which it was drawn.
- a surgical light comprising,
- said light head having an open end, a line closing said open end,
- a conduit for air inside said hollow are communicating with the inside of said head
- conduit means being concentrically disposed inside said hollow arm.
- said light head is in the form of a cylinder having an open end and an adjusting cylinder telescopically received on said open end,
- said adjusting cylinder being adapted to be moved on said light head and to be removed and sterilized.
- sealing means is provided between said light head and said adjusting cylinder
- said sealing means comprises an O-shaped sealing washer.
- said means to circulate air comprises a blower supported on a wall, and said extension arm is attached to said wall and said extension arm extends through said wall whereby air is discharged through said wall and is drawn in from the side of said wall remote from said light.
- a surgical lamp comprising a cylindrical housing having an open end
- a generally cylindrical reflector concentrically disposed in said housing.
- an air-circulating means having an inlet and an outlet
- said outlet of said air-circulating means being connected to said conduit whereby air is circulated through said conduit, over said lamp and out said hollow arm.
- said lens being disposed adjacent said operating site.
