a) Field of the Invention:
The present invention is in the field of surgical illumination and sterilization related to the large overhead light fixture used to illuminate a surgical site or other site of interest in a medical procedure, whether in an operating room or any other area where sterilization is critical. The surgical light fixture, typically includes a plurality of lights, the fixture being mounted to the ceiling, a wall or may be on a pedestal. Though the term large is used, surgical lights come in varying sizes and diameters.
A surgical light fixture, also referred to as an operating light or surgical lighthead, is a medical device intended to assist medical personnel during a surgical procedure by illuminating a local area or cavity of a patient. A combination of several surgical light fixtures is often referred to as a surgical light system.
In use, the lighthead is typically manipulated by the surgeon, during a sterile procedure on a patient. In the procedure, the surgeon and other medical personal will wear sterile gloves on their hands. The surgeon's hand will hold the handle of the lighthead to move and direct the beams of light from the lighthead to the area desired to be illuminated by the surgeon during the procedure. A surgeon or other medical person may adjust the lighthead several times during a procedure, each time by holding the handle of the lighthead. Though the lighthead fixture holding the lights is not sterile, it is desirable that the light handle which is a part of the lighthead and used by the surgeon to adjust the lighthead, and which comes in contact with the surgeon's sterile gloved hand, be sterile. It is known in the art to use replaceable lighthead handles or sterile covers for the lighthead handle, “light handle covers” on the lighthead handle to create an area on the lighthead handle “light handle” that is sterile.
These replaceable sterile handles or covers, as known in the art, can either slide onto the lighthead handle, for example where the lighthead has a male type handle connector. Alternatively a lighthead can have a female type handle connector in the form of an internal threaded opening to receive a replaceable handle with a male end to screw into the female connector of the lighthead.
Typically the replaceable handle covers are replaced at least for every procedure, and often times, they are necessarily replaced during the procedure, when the replaceable sterile handle cover comes in contact with an object that is not sterile. The surgeon's sterile gloved hands are sterile, and it is this sterile glove on the surgeon's hand that contacts the light handle when the light handle is adjusted or manipulated. However during a procedure other objects may accidentally come in contact with the light handle which contaminates the sterile handle cover. Such objects may be a person's head, a surgeon's head or nurse's head or an attendant's head, whether or not the head is covered, or for example an adjacent lamp or lighthead that is not sterile can contact the light handle and contaminate the light handle. Thus, during a procedure if it is noticed that a nonsterile object contacts the sterile light handle cover then the now contaminated light handle cover must immediately be removed and replaced with a clean sterile light handle cover. This replacement is typically performed by a person in the operating room other than the surgeon. This replacement takes time and interrupts the medical procedure while the contaminated light handle cover is removed, disposed and then replaced with a new sterile light handle cover. During a procedure, it is possible that this contact goes un-noticed. Most importantly, this contact between the adjacent objects and the light handle causes bacterial contamination of the surgical field and that greatly increases the risk of infection that is caused from the contaminated light handle.
The present invention is a shield or guard and light handle to be used on the handle of a lighthead in an operating room during a surgical procedure, when it is required that the light handle of the lighthead be sterile. The shield of the present invention prevents or limits other objects from coming in contact with the sterile light handle cover of the lighthead that the surgeon's sterile gloved hand contacts when the surgeon is manipulating the lighthead. The present invention can also provide tactile feedback to alert the person touching the light handle, when the sterile handle is contacted by the person.
The shield of the present invention can take several forms, a shade that extends around the light handle allowing sufficient room for a surgeon's sterile gloved hand to reach in to grab or hold on to the sterile light handle. The shade may be a solid wall surrounding the light handle, or it may have two or more elongated strut members or wall portions surrounding the sterile light handle cover, such that the wall prevents an object from coming in contact with and contaminating the sterile light handle cover.
Further the shield can also be at the base or terminal end of the light handle cover to likewise maintain the sterility or integrity of the sterile handle and/or limit contamination from an object coming in contact with the protected grip portion of the sterile light handle.
Additionally, the shield can extend below the plane of the terminal end of the light handle to prevent objects from coming in contact with the protected grip portion of the sterile light handle. These embodiments can be combined as well.
Therefore, it is a primary object of the present invention to protect the sterile light handle and limit contamination of the sterile light handle preventing contact from non-sterile objects. Thus diminishing the risk of infection.
It is another object of the present invention to guard against the unknown of not knowing the sterile handle cover came in contact with a non-sterile object by providing tactile feedback when contact is made.
It is a further object of the present invention to maintain the sterility of the grip portion of the sterile light handle and limit contact, whether known or not, with contaminated objects.
It is another object of the invention to place guards or obstructions around the sterile light handle. These obstructions include but are not limited to a wall, a shade, an elongated strut member, fingers or a base guard or flange at the terminal end of the light handle or the light handle cover.
It is a further object of the invention to increase the potential for recognizing contact with the light handle by creating notice or feedback or tactile feedback of the contact to the person causing the unwanted contact, by having a shield to protect the sterile area of the handle. This notice or feedback can be by an audible or visual notice or feedback, for example an audible alarm could be triggered or a light could be switched on to provide notice or feedback in the operating room to not only alert the person that caused the unwanted contact but to alert the person in charge of replacing the sterile light handle to replace the contaminated light handle.
It is another object of the invention that the shield of the present invention limit contact with the sterilized area of the light handle. Such that the shield will create feedback to give notice, a tactile feedback, to the person causing the contamination, so the contaminated handle can be replaced quickly. By way of example the tactile feedback can be any form of tactile communication to the person causing the contamination to provide notice of the contamination or possible contamination of the light handle or lighthead itself.
It is a further object of the invention to protect the sterile light handle from lateral contact at the sides of the handle.
It is an object of the present invention to prevent contamination of the light handle cover and thus limiting changing of the sterile handle cover.
It is another object of the invention to have a protective shield around the sterile light handle cover at a distance that is sufficient enough to accommodate insertion and withdrawal of a user's or surgeon's hand to hold the sterile area of the light handle.
It is another object of the invention to maximize surgery time and prevent interruptions during surgery due to contamination of the sterile light handle by limiting contact of contaminated objects with the sterile portions of the light handle and cover.
It is another object of the present invention that the shield be made of a material that is disposable, alternatively the shield can be reusable after use by treatment with a sterilizing machine as known in the art.
It is another object of the invention that the shield will not interfere with any opening in bottom of the handle cover that is used for accessories such as a camera lens or other device.
It is also an object of the invention that the shield includes a light handle cover portion, alternatively the shield can attach to lighthead handle while a separate or independent light handle cover is used. The sterile light handle cover may be independent of the shield of the present invention.
It is another object of the present invention that guard members or struts or portions of a wall can depend from the base of the lighthead or the peripheral edges of a lighthead to prevent an adjacent lighthead from coming in lateral contact with the handle of the lighthead.
In an alternate embodiment, the shield is incorporated into the lighthead with the handle therein.

The protective handle shield 10 of the present invention, as seen in the figures includes a handle grip or light handle 20. Light handle 20 has a terminal end 22 and shield 10 has a base 30. Base 30 has an upper flange 32 having a circumferential wall 34. Depending from the base 30 are one or more walls 36. The light handle 20 defines a longitudinal axis LA. The wall 36 extends from base 30 in the longitudinal direction of the longitudinal axis LA. Additionally, wall 36 may also extend in a radial direction from light handle 20 along longitudinal axis LA.
Light handle 20 has a center opening 12 for rigidly mounting shield 10 on to shield 10. As is known in the art, the internal surface of said opening 12 may have a plurality of elongated ribs 57b, to increase friction against male handle connector 57. The shield 10 has a mounting interface that in a first embodiment is for mounting shield 10 to a male connector 57 of a lighthead 50. In a second embodiment, the mounting interface is a threaded female opening 58 to receive the male handle connector 59. Irrespective of the mounting interface between shield 10 and lighthead 50, there is a light handle 20 as shown which has a cylindrical shape, though light handle 20 can be of any shape, including oval, square, rectangular or octagonal. Light handle 20 has an outer wall 21 and an inner wall 23 which would be the inner wall of opening 12.
Base 30 has an upper flange 32 which is circular, but can be of any shape, including oval, square, rectangular or octagonal. Upper flange 32 has a lighthead side 32a, a handle terminal side 32b and a flange height FH, which is also the thickness of circumferential wall 34. Walls 36 have an outer surface 37, an inner surface 38 and side walls 39. Walls 36 have a wall thickness ST substantially the same as the flange height FH of circumferential wall 34, and a wall width SW. The wall thickness ST is substantially the same as the wall width SW. The wall thickness will depend upon the material that wall 36 is made. The stronger the material, the smaller the thickness. If metal, in a preferred embodiment the wall width SW could be one centimeter and the wall thickness ST could be one tenth of one centimeter. If made of plastic SW could be one centimeter and ST could be one centimeter. The walls 36 can be solid or hollow having a cross section B-B taken from
Light head 20 has a sterile handle cover grip portion SH defined by height HH along the outer surface 21 of light handle 20.
