Aug 7, 1962 G. o. UDDENBERG CERVIX RETAINING INJECTION NOZZLE Filed March 50. 1959 INVENTOR. 617/6611? G01/2id Mm.: ABC

United @rates iiatent @dice 3,048,175A -Patented Aug. 7, 1962 3,048,175 CERVIX RETAINING INJECTION NOZZLE Goran Olot Uddenberg, Rangeltorpsgatan 49, Goteborg, Sweden Filed Mar. 30, 1959, Ser. No. 802,714 v Claims priority, application Sweden dan. 28, 1959 2 Claims. (Cl. 12S-245) This invention relates to improvements in instruments toV facilitate the examinations of and injections into the human uterus and Fallopian tubes.

One object of the invention is to obtain an instrument fora sure retaining of the cervix in a fixed position during examinations of and injections into the uterus and Fallopian tubes.

A further object of the invention is to obtain an instrument for a sure retaining of the cervix in a fixed position and at the same time to create a sure guiding of an injection device into said cervix.

When carrying out examinations of the uterus and Fallopian tubes one uses, according to the examinations, fluid or gas injections as a method of help, these injections are carried out through the cervix. Contrast .fluid is injected before X-ray examinations and flushing iiuid after operations. Gas injections, for example carbon-dioxide, are carried out to determine if the Fallopian tubes give free passage. It is, therefore, important that the cervix is held in an unchanging position so that the opening of the cervix can be found without diiculty and the insertion of the injection cannula greatly facilitated. This retention is normally obtained with the use of forceps, but this method often causes injury and yabrasion to the delicate tissues and at the same time difficulty can be experienced in the entry into the uterus through the cervix. j

A still further object of the invention is to overcome these diiiiculties. v.

With these and fur-ther objects in view the invention is essentially characterised in the fact that the instrument consists of an air-withdrawal vacuum-acting suction cup for enveloping and retaining the cervix, which works in cooperation with `an axiaily pre-adjustable opening device for the cervix, whereupon both the suction cup as well as the opening device form, in the operation position of the cervix, seals against the entry of air through the suction cup opening against the cervix.

One embodiment of theinvention is illustrated in the accompanying drawing, wherein:

FIGURE l shows a longitudinal section of the instrument in position against the cervix, `and FIGURE 2 shows a corresponding view of the instrument in the operating position with the inducted cervix.

The instrument consists of a cannula tube l, which is encompassed, with certain clearance, by an outer tube 2, this clearance forms a channel 3` between these two tubes. The outer tube is anchored in the forward section 4a, of a transversely divided handle, the rear section 4b, of which is, through the medium of a threaded stub 5, attached rin the forward handle section and contacts against a flexible seal ring 6, which is .situated around the cannula tube 1. This seal ring, which lies against the bottom of a recess corresponding to the stub 5, in the forward handle section, prevents air leaking along the outside of the cannula tube into the rear end of the outer tube, which lies further forward in the handle and also retains the cannula tube with a certain frictional force in the set position. In the forward handle section is a transverse tube 7 from the outer tube for connecting to a vacuum pump, which is not shown in the drawing, or a similar device for exhausting air from the suction cup. The outer pipe has, at its forward end, a flange equipped internally threaded muti 8, the end flange of which lies against a rubber gasket or something similar 9, which in its turn lies against the outside of the suction cup. A hanged nipple 10 is threaded in the end mud from the inside of the suction cup, the cannula tube passes through this nipple, with a clearance, into the suction cup. The cannula tube has an end head 11 at this end, which is, for example, in the form of a cone as shown in the drawing. The nipple can be screwed in with a suitable key and its ilange presses a Washer against the inside of the suction cup. The outer pipe is retained to the suction cup during sealing through the abovementioned rubber gasket 9 and is in communication with the interior of the suction cup by means of the clearance in the nipple. The suction cup circular suction opening 12 has an opening edge, which merges into the wall section of the suction cup, which is directed considerably outwards and forms, with the extension of the suction opening plane, a vary small angle. In this way the suction cup obtains, in comparison with the suction opening, a considerable transverse curve 13, which is shown in the drawing. lt is advantageous if the suction cup is of transparent plastic or something similar.

The rear handle section 4b has in its outer end an axial longitudinal recess 14, which contains, if determined suitable, ya fiexible seal ring 15', which encircles the cannula tube 1. In the recess is threaded a cannula tube retainer 16, the length of which corresponds to the length of the recess, the outer end of this retainer has an end head 17, which is used for screwing the cannula tube retainer in and out of the rear handle section 4b. This retainer has also, seen from the outer end, an axial recess, in which a connecting tube 18 is threaded, and is of such a length that it normally reaches the bottom of the recess so that through the pressure of another flexible seal ring 19 around the cannula tube obtains fr-ictional retention of the cannula tube. This reaches a little way into the con-v necting tube with its outer end in connection against a shoulder 20. The connecting pipe can house any suitable outer connecting head for connection to gas or liquid pipe connections. On the drawing is shown a normal connecting part 21 for a syringe. The cannula tube retainer has in its outer threading three impressed marks A, B and C, which show how far the cannula head 1.1 has reached out in connection with the suction cup. A

shows the bottom position of the end head and C showsv the maximum outer position. B shows the intermediary position.

When the instrument is used `the suction cup and the cannula tube end head are inserted in the cervix so that the suction cup opening surrounds the cervix annular muscle 25, and the forward end of the endhead enters the cervix as shown in FIG. 1 on the drawing. This is facilitated by the transparency of the suction cup. The end head should be in thebottom position with the cannula tube retainer 16 completely screwed out so that the mark A is just outside the outer end edge of the rear handle section 4b. The inner air should noW begin to be exhausted by the vacuum pump or similar device from the suction cup through the outer tube. The formation of a vacuum will cause the annular muscle to be inducted through the suction cup opening between the opening edge and the cannula tube end head, 'as is shown in FIG. 2; this will cause -an outward folding of the ring muscle 2S into the suction cup, and it will yalso glide over the'end head so that the suction cup and the end head will form a sealing surface against the inducted muscle, and a powerful retention by the suction cup will be obtained. During this time, or immediately after, the cannula tube end head should be inserted through the cervix by screwing in the cannula tube retainerl into the handle. For this movement the connecting tube 18, inner shoulder 20, moves the cannula tube forward vand the insertion is judged spaans by marks B and C. In this way the cervix -is opened so that free injection of liquid or gas can be carried out. With greater insertions the cervix can also be formed 1nto a complete fold at the base of the end head, as shown in FIG. 2, with further improved sealing conditions.

It the cannula tube end head is to be withdrawn or is to be adjusted in the reverse direction, the rear handle section should be loosened somewhat, so that the seal ring frictional tension decreases. When the cannula tube retainer 16 is screwed out, the cannula tube will come with it owing to the frictional eiect of the seal ring 19.

With the above described device one obtains a simple and effective instrument which, without pain or injury,

retains the cervix and holds it in an unchangeable position for the intended purpose.

As diierent conditions require cannula end heads of various sizes as well as various forms, for example fiattened form, ball form etc., the instrument has been constructed so that the cannula tube and end head can be easily replaced by drawing out the cannula tube through the suction cup and itting a new cannula tube and end head into the instrument through the suction cup. This is of great advantage when fitting surgical appliances as the cannula tube and end head can be replaced without the aid of tools and without any great loss of time.
