DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION

(8) Various aspects of the present device will become apparent for the following detailed description of the preferred embodiments thereof. Such embodiments should be referenced to the prior described drawings to fully understand the device sought for patenting.

(9) The device of the present invention is shown in the drawings by reference character 10, FIGS. 3-6. Referring to FIGS. 1 and 2, it may be observed that prior art positioning mechanisms for surgical mask 12, such as the PRONEVIEW product, is shown. Prior art mask 12 is depicted in FIG. 2 as including a soft foam liner or insert 14 and is supported above a mirror 16. Mirror 16 lies above a surface 18 which may be the top portion of a surgery table. A plurality of adjustable legs 20 fixed to mirror 16 allow the movement of surgical mask 12 away from and toward mirror 16. Surgical mask 12 also includes a plurality of bosses 22 which engage adjustable legs 20. With reference to adjustable leg 24, typical of the plurality of adjustable legs 20, an upwardly projecting rotatable screw 26 engages a threaded cap 26 placed within boss 30. To operate the adjustment mechanism of adjustable legs 20, surgical mask 12 must be lifted above mirror 16 and placed upon the projecting screws, such as screw 26, of each adjustable leg 20 in order to allow the threaded caps, such as cap 28 of adjustable leg 24, to engage each one of the plurality of bosses 22. Directional arrows 32 and 34 indicate the downward placement of surgical mask 12 on plurality of adjustable legs 20 via plurality of bosses 22.

(10) Looking now at FIG. 3, it may be observed that an exemplary adjustable leg 36 of the present invention is depicted. Conventional surgical mask shell 38, shown partially in FIG. 3, includes an extending boss 40 which is a hollow member of roughly cylindrical shape. Adjustable leg 36 includes as one of its parts a first threaded element 42 having an exterior ribbed surface 44 and a head 46. A thread 48, best shown in FIG. 4, lies within the interior chamber 50 thereof. A connector in the form of a mastic layer 52 positions between rib surface 44 of element 42 and the interior surface 54 of boss 40. Thus, first threaded element 42 is fixed to boss 40 in this regard. Of course after types of connectors may be used to fix first threaded element 42, as heretofore delineated.

(11) In addition, adjustable leg 36 further possesses a second threaded element 56. Second threaded element 56 is provided with an externally threaded surface 58 which is capable of threadingly and rotatably engaging internal threaded surface 48 of first threaded element 42. Of course, the relationship between external threaded surface 58 and internal threaded surface 48 may be reversed such that first threaded element 42 includes an externally threaded surface while second threaded element 56 is provided with an internally threaded surface. In any case, the turning of second threaded element 56 moves the same relative to first threaded element 42, boss 40, and mask 38 fixed thereto. A bore 60 in second threaded element 56 may be employed to receive a filler or cap that may be inserted into bore 60 through surgical mask shell 38. An opening 62 through end portion 64 of second threaded element 56 is intended to interact with rotatable handle 66, more fully described below. Rotatable handle 66 is also provided for in adjustable leg 36.

(12) Rotatable handle 66 includes a body portion 68 with a rounded outer body portion 70. Handle 66 is also fashioned with a protuberance or projection 72. A threaded passageway 74 through body portion 68 of rotatable handle 66 is intended to accept a threaded fastener 74 that engages openings 62 within end portion 64 of second threaded element 56. Opening 62 may also include an internal thread. In any case, second threaded member 56 is secured or fixed to handle 66 in this manner, such that rotation of rotatable handle 66 also turns or rotates second threaded element 56. It should be noted that the outer surface 76 of rotatable handles 66 includes a plurality of recesses 78 to facilitate the gripping of rotatable handle 66 by the user of adjustable leg 36.

(13) Positioning device 10, including adjustable leg 36, may also include an adjustable leg 78 which is constructed in a similar manner to adjustable leg 36. In fact, all the legs 36, 78, 96 and 98 associated with surgical mask shell 38 may include the same adjustment mechanism as that found with respect adjustable leg 36 prior described.

(14) Referring now to FIG. 5, device 10 also utilizes a mirror 80 having an upper reflective surface 82 and a perimeter 84. Mirror 80 is intended to lie above a surface 86 which may be the upper portion of a medical or surgical table. Mirror 80 also includes orifices 88, 90, 92, and 94, aligned with legs 36, 78, 96 and 98. As shown in FIG. 5, legs 96 and 98 associated with surgical mask shell 38 are similarly constructed to adjustable legs 36 and 78. That is to say, a protuberance such as protuberance 72 of rotatable handle 66 of adjustable leg 36, is found on adjustable legs 78, 96, and 98, associated with bosses 100, 102 and 104 of surgical mask shell 38.

(15) In operation, FIG. 5, the user places surgical mask shell 38 atop mirrors reflective surface 82 near orifices 88, 90, 92, and 94. Surgical mask 38 having adjustable legs 36, 78, 96, and 98 rest atop reflective surface 82 of mirror 80. Surgical mask shell 38 is then slid along reflective surface 82 of mirror 80 to allow protuberance 72 of adjustable leg 36 to engage orifice 88 according to directional arrow 106. Simultaneously, protuberances similar to protuberance 72 associates with adjustable legs 78, 96, and 98 engage orifices 90, 92, and 94, respectively. Surgical mask shell 38 is then secure in place atop mirror surface 82 apart from perimeter 84 of mirror 80. Such positioning, as may be seen, takes place without lifting surgical mask 38, and allows the perimeter 84 of mirror 82 extend outwardly from adjustable legs 36, 78, 96, and 98 as needed to allow the surgeon to observe the eye area of the head of a patient lying within surgical mask shell 38 atop an foam liner (not shown) in FIG. 5. Once in place, surgical mask shell 38 may be adjusted by turning handle 66 of adjustable leg 36 as well as comparable handles for adjustable legs 78, 96, 98. In other words, surgical mask shell 38 moves up and down, or tilts, relative to mirror 80 as needed. FIG. 6 indicates the turning of handle 66, directional arrow 108, to effect the movement of exemplary adjustable leg 36. Rounded outer body portion 70 of rotatable handle 66 facilitates the turning of handle 66, FIG. 6.

(16) While in the foregoing, embodiments of the present device have been set forth in considerable detail for the purposes of making a complete disclosure of the device, it may be apparent to those of skill in the art that numerous changes may be made in such detail without departing from the spirit and principles of the invention.
