My invention relates *to an improved cannula and "more particularly to an 'Einsufflation cannula especially adapted dor introduction in the cervical canaLo'f' the uterus.
The object of this invention is to provide a device of this kind consisting of a combination adapted to be use'd'for diiferent medical purposes.
More particularly the new device according to my invention is useful for carrying out the Rubin test, as well as :hysterosalpingography.
-As known' to those skilled in the medical art, the Rubin test consists of testing thepermeability of the oviductsby means ofblowing'air or carbon dioxide through the external 'os, after an airtight closure of'the cervix has'been accomplished. A manometer indicates whether "the tubes are open or *closed.
'-I-I ysterosa1pingographyconsists of filling the tubes and the -uterus *with a contrast medium for the purpose of using X-rays'to determine whether the 'tubes'are open or closed,'andtovi sua1ize the contours -'of the uterus.
Other objects, novel features and advantages of my invention willbecome apparent from the following specification and acc mpanying drawing, wherein one "embodiment :of my invention is shown.
In-the drawings:
Figure 1 :is a perspective wiew of a cannula embodying the invention.
Fig. 2 is a front view 'of part of the-instrument according 'to -Fig. *lppartlfbroken.
*Fig. .3 is a longitudinal section or the lower part of "the instrument 1m an enlarged scale, presenting an interchangeable tip.
Fig. 4 'shows a modified form of the interchangeable tip accordingtoFi-gsfi. v
Fig. 5 is a side view of the part shown in Fig. 2, partly in :section.
Fig. 6 is a detail showing the provision of an inflatable tubing on :the instrument.
Fig. '7 shows the same detail as Fig. 6, the tube being inflated.
Figs. 8.29, and 1 1 are sections through line 8-8 of Fig. lgshowingcavthree-waypock p ovided in thispart of the instrument, in .difierentpositions.
"Referring to said drawings, the *improved instrument comprises an externa tubular member I, the "size and shape "being 'that of .a regular uterine sound. Inside..two tubes 3 and"; are rovided. "Iiube 31s .provided with alateral o"t et.5 somewhat below its closed upp r end .6, which corres onds to a lateral out et on tube 1. "Tube '4 extends somewhat above tube 3. It is provided at its upper end with :means :foriinserting an .interchangeable tip, :for instance, with a ".thread "1.
vAshort tip 8 itoriintra-scervical'useris rshown in Fig. 3. A rlongerttip 29 for insertion the :uterine cavity :is shown =14. At the top of thettips a plurality .of mperiings 2| .0 zistprovided.
tNear its sl'owerrendunember =1 :iszenc'losedby a jacket :12, :composed =nf an elastic material, such as rubber, coagulatedilatex, etc.,.=said"jaeket:coveringnpeningrkl. .Thezrubberijaeket isihelddn position :onthe tube 1 by means of (threads it. :By pressing air through tube3 zthe jacket 12 can'be dilated to form a. ibeilloon adaptedto accomplish an air-tight closure .ofitherexternalopening of :the
cervixwhen "the ss'leeve us ilnserted the cervical ?In :order ito :make the new device useable for diiierent purposes, distributing means are :provided atithewupper part of the instrument.
These means :eomprdse ra three way valve M which :is provided in the center of a casing 15. Said casing is arrangedmn thetop o'f' the tubular member l wl'iih surrounds the main partsof the tubes 3 and 4. The casing enoloses --the upper parts of-saidtubes band 4 extending from said tubular member Tube 4 is arranged in the eenter of easing l5, its upper open end leading ito the centerof-valve M. Tube *3 leads to the top of easing [5. it is plu ged and thereby closed 'by a screw 15' provided at the top ofcasing T5. Tube-3 is situated to"touch tangentially thes'ide o'f valve l' l. Tube 3 is closed at the 'top and an opening 1 6 is provided at the point :of contact -between valve and tube.
A short tube or hut) -l is centrally placed at the top of 'casing [6, providing a connection between the casing *and the outside "of said tube Pl, =and=positioned inline with the part-of tube '4 which is inserted in the casing.
A'connecting hub IB sin'iiIartOhHb 'II, is'provided'at' the lowerright sideof-casing [5. A tube I9 *arranged at an'a ngle '01 -45 to the side face of the :casing -connects said hub [3 with the valve M.
The valve M is *controlled by a dial knob 2,8 which is arranged outsidethe casing and attached to valve Hi, The -wholevalve assembly is fixed inthe casing and *heldtogetherby washer 20 and screw 20'.
"Means are provided for 'indexingthe .difiierent positions of the three-way valve, thus gassuring correct alignment with the *various "conduits :in the casing. One embodiment offthe indexing and aligning dev ceis showni-in Fig. "2, and a modification in Fig. 5.
As shown in Fig. 2, cavities 2| are provided on the outside rim of knob 28 in appropriate positions. A plate with an elastic tongue 22 is held in position above knob 28 by hub l1. Tongue 22 is provided with a spherical rivet 23 which is pressed against the rim of knob 28. When this knob is turned around the rivet 23 will engage the different cavities 2| which correspond to dial marks provided on the outside of knob 28, thereby indicating the actual position of the valve.
In the modification shown in Fig. 5, cavities 24 are provided on the lower side of dial knob 28, corresponding to the marks of the dial. When the knob is turned around a spring loaded ball 25 provided in the casing engages one of said cavities 24 and fixes the knob and indicates the position of the valve. The described means makes it possible to use the instrument in not too bright light, for instance, in the X-ray room, since the change of position of the three-way valve effected by'turning the dial can be felt by the operator.
Various instruments can be adapted to the different connections leading to the inner side of the casing. .A syringe 26 maybe connected, for instance, with the instrument through hub 11. A manometer 2! may be attached to hub 18.
Different possibilities for using the new instrument will become apparent from the following description of its application.
As shown in Figs. '1 and 2, the dial indicates four poss b e positions of the three-way cock, namely, .B. C, X, and FR.
Position "B is shown in Fig. 8. In this position a direct connection is provided between hub l1. towhich syringe 26 may be attached, and tube 3 leading to rubber sleeve 1 2, which can now be dilated to form a balloon closing the external opening of the cervix.
Position C of the cock is shown in Fig. 9. In this positionthe device is closed. There is no connection from the outside with any of the conduits'provided in the casing;
Position X of the cock is shown in Fig. 10. In this case hub is directly connected with tube 4, thus forming a straight connection from the syringe to the uterus. This position is used for injection of contrast mediums for examination by X-ravs, or salpingography.
Position R of' the valve is shown in Fig. 11.
In this" case tube 4 leading to the uterus is connected with-hub 11. There is also a connection between hub; l8 and tube 4; This is the position for carrying out the Rubin test. To accomplish this a 20 ccrsyrin e isattached to hub IT and an ordinary manometer to b b l8.
In using the new'insufilation cannula according to my invention -the' device" is first placed C, shown. in Fig. '9, thereby cutting oflf any out-- side connections.
. In order to carry out utero-salpingography, the disk28is turned into position X (Fig. 10) thereby forminga direction connection between hub and tube 4. a
. The X-ray contrast mediumis-injected with a Luer syringe through hub I1. Incase fractional injection of the contrast medium is preferred the valve 14 is moved into position "0 (Fig. 9) by turning disk 28 accordingly thereby closing the device between the different injections.
To carry out the Rubin-test valve 14 is brought into position R (Fig. 11) by turning disk 28 accordingly. A 10 or 20 cc. Luer syringe filled with air or CO2 is attached to huh I! and a manometer 2'! is attached to hub 18.
In case the Rubin test is to be made with Kymographic equipment position X is used. In this case the tube of the Kymograph must be attached to hub H. 7 Among the advantages of this instrument over others are its simple use, the air-tight closure of the cervical canal, atraumatic application and painless use. Another advantage which will be apparent to the medical profession is that with this instrument there will be no change in the position of the uterus during the test.
The foregoing description and drawing describe the instrument in What I consider a preferable form, but it Will of course be understood that the instrument may be varied Without altering the principle of th invention.
Such changes may be made as desired which fall within the scope of the appended claims.
I claim:
1. An insufilation cannula usable for different medical purposes comprising an elongated tubular body of the size and shape of a regular uterine sound, said body surrounding two conduits, one of said conduits leading to an exchangeable tip provided at the outer end of said tubular body, the other one having a lateral outlet corresponding to a lateral outlet provided on said tubular body; an elastic, inflatable sleeve surrounding said outlets and a distributor provided at the top of said body comprising two hubs leading out of the instrument, and a three-way cock adapted either to close the instrument or to connect each of said tubes With said hubs, one of said hubs being adapted to be connected with means for filling the Fallopian tubes and the uterus with a contrast medium for X-ray examination and with means for testing the permeability of the oviducts, respectively.
