Abstract
A vaginal lateral walls retractor for use with a vaginal speculum to retract the vaginal lateral walls during vaginal/cervical examinations includes a generally tubular sleeve having cross-sectional dimensions that allow the sleeve to fit in between blades of the speculum while the blades are inserted and opened within a vagina. The sleeve retracts the vaginal lateral walls that have pushed in under the inserted and opened speculum blades. The cross-sectional dimension also provides an inside working area for examination and sampling of the vagina and cervix area.
Description




TECHNICAL FIELD




This invention relates to the performing of vaginal and cervical examinations and more particularly to an apparatus to be used in combination with a vaginal speculum to retract vaginal lateral walls during a vaginal examination.




BACKGROUND OF THE INVENTION




It is known in the art relating to vaginal and cervical examinations to use a vaginal speculum to enlarge the passage through the vagina for gynecological examination, sampling or treatment. Problems arise when conducting visual vaginal and cervical examinations with a conventional two-bladed vaginal speculum on women who are obese, elderly, have excess adipose vaginal tissue, or otherwise poorly toned vaginal walls.




It is often impossible to obtain a complete view of the cervical area and/or impossible to collect valid PAP smear samples because the vaginal walls' excess or relaxed tissue structure of the lateral vaginal walls pushes back in under the speculum blades after the speculum is opened. To overcome this problem, the clinician usually has to insert a pair of metal, surgical, lateral wall retractors inside of the opened speculum. These lateral retractors are expensive and clumsy, and thus nonconducive to single patient use and sampling.




Several other techniques have been unsuccessfully used to solve this problem. For example, condoms or portions of surgeon gloves have been placed over the closed speculum blades before insertion into the vagina. Unfortunately, the condom often simply rolls or slides up the blades during insertion, bunching up, rendering it useless. Further, the condom usually does not have enough force, when the blades are opened, to hold back the vaginal lateral walls. Furthermore, the condom may slip off when the blades are being removed and be left behind in the vagina. Therefore, there is a need for a device that can be used with a vaginal speculum to retract the vaginal lateral walls and which is also disposable, reliable, and cost effective.




SUMMARY OF THE INVENTION




The present invention provides a vaginal lateral walls retractor for use with a two-bladed vaginal speculum during vaginal or cervical examinations. The walls retractor includes a generally tubular sleeve that has cross-sectional dimensions that allow the sleeve to fit between the blades of the speculum while the blades are inserted and opened within the vagina. The sleeve retracts the vaginal lateral walls that have pushed in under the inserted and opened speculum blades. The cross section also provides an inside working area for examination and sampling of the vagina and cervix area.




In one embodiment of the present invention, the sleeve has a length that is about 60% of the length of a blade of the speculum. A handle extends from one end of the sleeve for manipulation by a health care provider. The handle has a length that allows full placement of the sleeve down to and around an outer diameter of the pendulous cervix and allows the sleeve to be pushed toward and away from anterior and posterior vaginal fornix and allows rotation of the sleeve inside the speculum blades.




In another embodiment, the cross section is of a generally rectangular shape with rounded corners. The sleeve has four sides and may have two cutouts on opposing sides at a proximal end of the sleeve so that an ectocervical scraper lobe will not hit the end of the sleeve. The cutouts may be of a generally elliptical shape. The sleeve may include a notch to accommodate a light pipe channel on a disposable speculum. The sleeve may be made of a plastic or metal material.




The present invention also provides an enhanced method of performing a vaginal or cervical examination on a patient. Thereby, blades of a vaginal speculum are inserted into a vagina. Once they are inserted, the blades are opened. Next, a vaginal lateral walls retractor defined by a generally tubular sleeve is inserted in between the opened speculum blades for retracting the vaginal lateral walls. To gain additional wall retraction, the vaginal lateral walls retractor sleeve is of an elongated rectangular shape. The rectangular sleeve is inserted with its longest cross-sectional dimension between the speculum blades and then rotated 90 degrees. Finally, the vaginal and cervical areas are examined and samples may be taken or treatment given.




These and other features and advantages of the invention will be more fully understood from the following detailed description of the invention taken together with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




Referring now to

FIGS. 1-3

of the drawings in detail, numeral


10


generally indicates a vaginal lateral walls retractor for use with a vaginal speculum


12


. The walls retractor


10


eliminates the problems arising when examining women who are obese, elderly, have excess adipose vaginal tissue, or otherwise poorly toned vaginal walls, with a two-bladed speculum


12


. Normally, the vaginal walls


14


will push back in under the blades


16


of the speculum


12


, obstructing the view of the health care provider and preventing the examination or sampling of the vaginal area as shown in FIG.


2


. The present invention allows the health care provider to obtain an unobstructed view and access of the vaginal and cervical areas by retracting lateral vaginal walls


14


as shown in FIG.


3


.




The vaginal lateral walls retractor


10


includes a generally tubular sleeve


18


. The sleeve


18


illustrated in

FIGS. 1-3

is of a generally rectangular or elongated oval shape and has cross-sectional dimensions


20


,


22


that allow the sleeve


18


to fit between the blades


16


of the speculum


12


while the blades


16


are inserted and opened within the vagina. The configuration of the walls retractor


10


allows it to be used with various sized specula. As the sleeve


18


is being inserted, it retracts the vaginal lateral walls


14


that have been pushed in under the inserted and opened speculum blades


16


. The cross-sectional dimensions


20


,


22


also provide a maximum inside working area


24


for examination and sampling of the vaginal and cervical area. The cross section is preferably of the generally rectangular shape but may also be circular, elliptical (

FIGS. 4 and 5

) or any combination thereof.




In one embodiment of the present invention, the sleeve


18


has a length that is about 60% of the length of a blade of the speculum and a rectangular shaped cross section as shown in FIG.


1


. With the tubular sleeve length at about 60% of the blade length, it is possible to rotate the rectangular sleeve


18


ninety (90) degrees after insertion. Such rotation provides additional lateral wall retraction due to the long dimension of the sleeve


18


being placed horizontally, from vertical; and extending between the lateral vaginal walls.




A handle


26


extends from one end


28


of the sleeve for manipulation by a health care provider such as steering, retaining and positioning the sleeve within the vagina. The handle


26


may have a portion


30


such as a hook that allows the provider to keep the handle


26


to one side of the speculum blades


10


for maximum through clearances for brush, spatula, scraper, external lights, catheter, dilators or other tools used during examination and sampling. The handle


26


has a length that allows full placement of the sleeve


18


down to and around an outer diameter of the ectocervix and allows the sleeve


18


to be pushed toward and away from anterior and posterior vaginal fornix.




Referring to

FIG. 3

, the inside working area


24


of the sleeve is the space within which the health care provider collects a cervical canal surface sample with the endocervical cytology brush, rotates the ectocervical scraper around the ectocervix for the ectocervical sample, and collects a sample from the posterior vaginal fornix with the spatula end. Having only a partial sleeve length (about 60% of blade length) provides for more maneuverability of the brush and scraper/spatula. Further, the partial sleeve length allows for excellent viewing of the vaginal area. Also, an excellent view of the area is achieved by having a notch


32


in the sleeve


18


to accommodate a light pipe channel


34


on a disposable speculum as shown in

FIGS. 4 and 5

.




The walls retractor


10


can be used directly or adapted slightly to work with any size or type, metal or plastic speculum. The walls retractor


10


can be made from either metal or plastic.




In a preferable embodiment of the present invention, the lateral walls retractor


10


has a rectangular cross section and may include two cutouts


36


on opposing sides


38


,


40


at the end opposite of the handle


26


or a proximal end


42


of the sleeve


18


so that an ectocervical scraper lobe will not hit the end of sleeve. The cutouts


36


may be of a generally elliptical shape as shown in

FIGS. 4 and 5

. Such a configuration may prevent the lobe of the ectocervical scraper from touching the sleeve walls, which may potentially interfere with vaginal wall cells collected for testing. Further, cutting out the end


42


of the sleeve


18


also yields a greater open area around the cervix, simulating the use of two specula, one in the horizontal-lateral direction and the other in the vertical direction. This is especially helpful when it is necessary to view the entire diameter of the cervix of a larger patient which may have up to a four (4) cm (1.6″) diameter.




Referring to

FIG. 5

, a lip portion


44


may inwardly extend from the side


40


opposite the handle


26


at a distal end


46


of the sleeve


18


. The lip portion


44


allows the sleeve


18


to be easily removed from the speculum


12


by preventing the sleeve


18


from getting hung up on a side of the speculum


12


during removal of the sleeve


18


.




In another embodiment, the sleeve length is slightly longer than the speculum blades


16


and extends outside the introitus of the speculum


12


after the sleeve


18


is inserted as shown in FIG.


6


. This configuration prevents the sleeve


18


from getting hung up on the introitus yoke of the speculum


12


upon removal of it from the speculum


12


, but does not generally allow 90° rotation of sleeve


18


.




The present invention also provides a method of performing a vaginal or cervical examination on a patient which includes the following steps. Blades of a conventional vaginal speculum are inserted into the patient's vagina. Once inserted, the blades are opened. Next, a vaginal lateral walls retractor of a generally tubular shape is inserted in between the opened speculum blades for retracting the vaginal lateral walls. To gain additional lateral walls retraction, the vaginal lateral walls retractor tubular shape is generally rectangular in cross section and the larger diameter of the cross section may be rotated 90 degrees to extend between the lateral side walls. Finally, the vagina and cervix area are examined and samples may be taken.




Although the invention has been described by reference to specific embodiments, it should be understood that numerous changes may be made within the spirit and scope of the inventive concepts described. Accordingly, it is intended that the invention not be limited to the described embodiments, but that it have the full scope defined by the language of the following claims.
