Abstract

A surgical headlight assembly having a headset structure constructed of lightweight components. The headset structure has adjustable head strap members comprising a generally circular lateral band and a top band. A removable liner is attached to the inside surface of the adjustable headset structure. A lighting assembly which is adjustable with respect to the headset and which uses an adjustable LED is also provided connected to the lateral band. A battery pack is utilized to power the LED.

Claims

1. A surgical headlight assembly comprising:

a) an adjustable and flexible headset structure, said headset structure having a headband member and a top strap member, said headband and top strap members each having a length adjustment means comprising a ratchet gear adjustment means;

b) a light emitting housing structure having connection means to said headband member;

said light emitting housing structure having an LED and a lens member, wherein said lens member is horizontally adjustable with respect to said LED and wherein said light emitting structure is adjustable with respect to said headset structure, wherein said connection means of said light emitting structure includes a pivotable arm structure and an attachment block, wherein said attachment block is mounted to said headset structure and wherein said pivotable arm structure has two pivotal ends, wherein one end is in pivotal and rotational communication with said attachment block and wherein said light emitting structure is pivotally disposed at the other end of said pivotable arm structure which thereby provides vertical and rotational adjustment means for said light emitting structure with respect to said headset structure; and

c) a power source for said LED.

2. The surgical headlight assembly of claim 1, wherein said light emitting structure is comprised of an inner housing for containing said LED and an outer housing for containing said lens member, wherein said outer housing is threadedly connected to and rotatable with respect to said inner housing, thereby permitting the controlled linear movement of said lens structure with respect to said LED.

3. The surgical headlight assembly of claim 1, wherein said power source is a rechargeable, hot-swappable Lithium-Ion battery pack.

4. The surgical headlight assembly of claim 1, wherein said attachment block and said end of said pivotable arm structure form a ball and socket configuration.

5. The surgical headlight assembly of claim 1, wherein said headset structure is constructed of a unitary polymeric structure having two top straps and two lateral straps, each of said top straps and said lateral straps having an elongated aperture with inwardly disposed ratchet protrusions, said headset structure forming said head band member and said top strap member of said headset structure.

6. A surgical headlight assembly comprising:

a) a flexible headset structure having a generally circular lateral band and a top band connected thereto said lateral band and said top band having inner and outer surfaces, said generally circular lateral band having an attachment block structure connected to said outer surface of said lateral band, said attachment block structure further having a socket disposed therein;

b) adjustment means comprising a ratchet gear adjustment structure and an operating knob operative to adjust the size of said lateral band and adjustment means comprising a ratchet gear adjustment structure and an operating knob operative to adjust said top band;

c) a removable liner attached to the inside surface of said circular lateral band and to said inside surface of said top band;

d) an adjustable arm structure having a first end and a second end, wherein a ball member is located at said first end and is constructed and arranged for rotational movement within said socket of said attachment block structure,

e) an adjustable lighting assembly connected to and extending from said lateral band, said lighting assembly further comprising an adjustable housing structure located at one end of said pivoting arm assembly and having an LED mounted therein, wherein said adjustable housing structure comprises an inner housing for containing said LED and an outer housing for containing a lens, wherein said outer housing is threadedly connected to and rotatable with respect to said inner housing, thereby allowing the controlled linear movement of said lens with respect to said LED;

f) power means in communication with said LED, said power means having an attachment structure; and

g) a nest structure secured to said generally circular lateral band, said nest structure being constructed and arranged having a receiving slot member to receive said attachment structure of said power means.

7. The surgical headlight assembly of claim 6, wherein said housing structure further has a filter located at the distal end of said outer housing.

8. The surgical headlight assembly of claim 6, wherein said attachment structure is a clip member and wherein said nest structure further having spring loaded ball plungers in said receiving slot to secure said clip member and wherein said power means is attachable to a user or to said nest structure of said headset structure.

9. The surgical headlight assembly of claim 6, wherein said power means includes rechargeable batteries and wherein said lighting assembly comprises at least one LED providing a color range of approximately 4800 to 6000K.

10. The surgical headlight assembly of claim 6, wherein said housing has cooling means selected from the group of cooling means consisting of cooling vents, a cooling fan and a heat sink.

11. The surgical headlight assembly of claim 6, wherein said power means includes a circuit regulator and an on/off switch.

12. The surgical headlight assembly of claim 6, wherein said removable liner comprises polyurethane or a CoolMax liner.

13. The surgical headlight assembly of claim 6, wherein said headset structure is constructed of a unitary polymeric structure having two top strap members and two lateral members, each said top strap member and said lateral member having an elongated aperture with inwardly disposed ratchet protrusions, said unitary polymeric structure forming said lateral band and said top band of said headset structure.

14. A surgical headlight assembly comprising:

a) a headset structure, said headset structure having a headband member and a top strap member, said headband and top strap members each having an adjustment means;

b) a light emitting structure having connection means to said headband member;

wherein said connection means includes a pivotable arm structure and an attachment block, wherein said attachment block includes a socket portion and is connected to said headset structure and wherein said pivotable arm structure has two pivotal ends, wherein one end is a ball portion and is in rotational communication with said socket portion of said attachment block and wherein said light emitting structure is pivotally disposed at the other end of said pivotable arm structure which thereby provides vertical and rotational adjustment means for said light emitting structure with respect to said headset structure, said light emitting structure further having an inner housing to house a light source and an outer housing to house a lens member, wherein said outer housing is threadedly connected to and rotatable with respect to said inner housing; and

c) a power source for said light source.

15. The surgical headlight assembly of claim 14, wherein said adjustment means of said headband and top strap members is a ratchet gear adjustment means.

16. The surgical headlight assembly of claim 14, wherein said headband has an inside and an outside and wherein said inside includes at least one portion of replaceable liner, wherein said liner is selected from the group of liners consisting of a Poron®

liner, a CoolMax®

liner and a CoolMax®

woven with silver liner.
