PIVOTED VAGINAL SPECULUM HAVING LINEAR AND ANGULAR BLADE ADJUSTING MEANS Filed Oct. 51, 1962 2 Sheets-Sheet 2 IN'VENTOR WILLIAM B MURPHY. JR.

United States Patent PIVOTED VAGINAL SPECULUM HAVING LINEAR AND ANGULAR BLADE ADJUSTING MEANS William P. Murphy, Jr., Miami, Fla., assignor, by direct and mesne assignments, to Cordis Corporation, Miami,

Fla., a corporation of Florida Filed Oct. 31, 1962, Ser. No. 234,909 4 Claims. (Cl. 128-17) This invention generally relates to surgical specula, and more particularly to a novel vaginal speculum.

In order to facilitate the examination and the treatment of interior body cavities it is necessary to employ an instrument to dilate such cavities. Specula of various kinds have been devised for this purpose.

Frequently specula are of a type that permit only rotary or arcuate relative movement of the blades. In such specula a pivotal or hinged connection is provided between the blades. As the blades are moved relative to one another they describe an arcuate path about a transverse axis passing through the pivotal connection.

In addition to this angular rotation of the blades it is necessary that the blades be bodily adjustable relative to each other. That is, the instrument should not only permit substantial angular rotation of the blades but should also permit relative linear bodily adjustment or separation of the blades in aligned relation.

Heretofore specula which have permitted these two distinct modes of adjustment have comprised four to six parts, and were relatively cumbersome, complicated and expensive devices. Another disadvantage was the difficulty involved in sterilization of such complex instruments.

Therefore the principal object of the present invention relates to a novel speculum of simplified construction permitting two distinct modes of adjustment of the blades.

A further object of this invention relates to a novel vaginal speculum comprised of only two parts and constructed to permit relative angular rotation as well as bodily separation of the blades.

Other objects and the entire scope of the present invention will become apparent from the following detailed description and by reference to the accompanying drawing. It should be understood, however, that the detailed description and specific examples while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent as the description herein progresses. Reference now being made to the accompanying drawings which form a part hereof.

In the drawing numeral 10 generally indicates one form of a duck-billed vaginal speculum constructed in accordance with my invention which may preferably be composed of metal or plastic.

As shown in FIGURES 1, 2 and 7 the speculum generally comprises two parts, lower member 15 and upper member 17. Lower member 15 includes a lower blade 11, two laterally projecting pin-like portions or trunnions 16 and handle portion 12, all integrally formed. Handle portion 12 is provided with a longitudinal slot 18. Upper member 17 includes an upper blade 13, an angularly projecting generally U-shaped portion formed by transversely spaced parallel arms 14, a lever portion 20 and a multiposition latch 19, all integrally formed.

Arms 14 are provided with longitudinal recesses 21 adapted to receive trunnions 16 of lower member 15 and to retain said member in pivotal and sliding engagement with upper member 17. To this end, retaining portions 22 and a plurality of fulcrum points 23, in the form of transverse serrations are provided in recesses 21 as seen in FIGURES 1-3 and 7. The fulcrum points 23 are adapted to pivotably engage trunnions 16 when in operative relation. The distance A, indicated in FIG- URES 3 and 7, between the inner surface of retaining portions 22 and the crests of fulcrum points 23 must permit suflicient clearance for trunnions 16 to disengage the fulcrum points 23 and slide longitudinally of recesses 21.

As best seen in FIGURE 1 multiposition latch 19 projects from lever portion 26 toward, and in alignment with, slot 18 in handle portion 12. Multiposition latch 19 is provided with a plurality of serrations adapted to resiliently engage the side walls of slot 18 so as to retain a given angular adjustment of the blades, as best seen in FIGURE 5.

Preferably lever portion 20 is provided with a plurality of ridges in order to facilitate gripping said portion.

Since trunnions 16 may slide longitudinally within recesses 21, it is readily seen that the blades 11 and 13 may be bodily moved relative to each other in aligned relation, as indicated by arrow BB in FIGURE 1. When the desired bodily separation of the blades is obtained, engagement of trunnions 16 with a pair of fulcrum points 23 prevents further bodily movement of the blades. It is thus seen that a wide range of blade separation is possible.

The blades may also be adjusted in angular relation, as indicated by arrow CC in FIGURE 1. By moving lever portion 20 towards or away from handle 12, trunnions 16 will each pivotably engage one of the fulcrum points 2.3 in recesses 21 and the blades will be angularly rotated relative to each other about a transverse axis passing through trunnions 16. As lever 20 is moved to rotate blade 13 away from blade 11, latch 19 will engage the side walls of slot 18.

It is apparent that my novel construction permits not only a wide range of bodily blade separations, but also a wide range of angular rotation of the blades.

Since the engagement of latch 19 with the side walls of slot 18 prevents angular rotation of the blades and the engagement of trunnions 16 with fulcrum points 23 prevents relative bodily movement of the blades, the blades will remain in their adjusted position within the body cavity. In fact, the pressure exerted by the walls of the body cavity tending to close the blades tends to force the trunnions into firmer engagement with the fulcrum points and thus increases the resistance of the blades to closing. The resistance of the blades to closing while within the body cavity is thus limited only by the resistance of the latch 19 to disengagement from the side walls of slot 18.

The following is an example of using my novel speculum. The speculum is inserted into the vaginal canal with the blades in completely closed position as shown in FIGURE 6. The upper and lower blades are separated the desired distance apart in parallel relation to each other. The upper blade is then tilted with respect to its companion blade by applying pressure to lever 20 which also causes the trunnions to firmly engage a pair of fulcrum points and the latch member 19 to engage the side walls of slot 18. The speculum is thus in the desired dilating position. The instruments necessary for the gynecological procedures are then inserted into the vaginal canal through the opening defined by arms 14 and the upper and lower blades 11 and 13.

FIGURE 4 shows a modified form of connection between the upper and lower blades which permits both bodily separation and angular rotation of the blades. In the modification shown in FIGURE 4 it will be seen that the lateral projections 24 do not engage the fulcrum points 23, but rather serve only to retain the blades in sliding engagement with one another. The projecting portions or shoulders provided on the rearward extensions of the lower blade are adapted to pivotably engage the fulcrum points 23 so as to permit angular rotation of the blades. As-in the preceding embodiment, the distance A between the inner surface of the retaining portions 22 and the crests of the fulcrum points 23 must permit sufiicient clearance for the shoulders 25 to disengage the fulcrum points 23 and slide longitudinally of recesses 21.

FIGURE 8 shows a modified form of my latch arrangement wherein the .multiposition latch 19' is integrally formed with the handle portion 12'. The multiposition latch 19' projects from the handle portion 12' toward, and in alignment with slot 18' in lever portion 20. Multiposition latch 19' is provided with a plurality of serrations adapted to resiliently engage the side walls of slot 18' so as to retain a given angular adjustment of the blades.

The present invention will thus be seen to completely and etfectively accomplish the objects enumerated hereinabove. By providing a speculum of my novel construction two distinct modes of adjustment are permitted, namely, both substantial angular rotation and linear bodily separation of the blades. At the same time the speculum comprises only two parts rather than the numer ous parts and cumbersome arrangements of the prior art, thus permitting simplified manufacture and operation in addition to facilitating sterilization of the instrument.

It will be realized however, that various changes and substitutions may be made to the specific embodiments disclosed herein for the purpose of illustrating the principles of this invention without departing from these principles. Therefore, while the present invention has been described with particular reference to the specific forms shown in the drawings, it is to be understood that such is not to be construed as imparting any limitations upon this invention, which includes all modifications encompassed within the spirit and scope of the following appended claims.
