RICHARD JENTZSCH, OF CHICAGO, ILLINOIS.

TUBE-INSERTER.

Specification of Letters Patent.

Patented Mar. a, rare.

Application filed April 30, 1915. Serial No. 25,002.

To all whom it may concern:

Be it known that I, RICHARD JnN'rzsoH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Tube-Inserters, of which the following is a specification.

This invention relates to surgical instruments and more particularly to devices for inserting and expanding uterine tubes.

The primary object is to provide a simple and eflicient device of the character described for the convenient insertion and expanding of uterine tubes such as is shown in my patent of Sept. 17, 1912, No. 1,039,061.

Another object of the invention is the provision of an instrument of this character which will have the required strength and rigidity to accomplish the simultaneous ex- 1 panding of the opposite legs or extensions of the tube and yet may be readily withdrawn from the tube and vagina without injuring the patient.

Further objects ofthe invention will apthe following specific description is read in connection with the accompanying drawings which form a part of the application and in which:

Figure 1 is a. sideelevation. Fig. 2 is a view taken at right angles to Fig. 1. Fig. 3 is an enlarged side elevation of the device showing in detail the arrangement of the jaws expanded and with one of the tubes mounted thereon and shown in section. Fig. 4 is a detail longitudinal section.

Referring more particularly to the drawing 1 represents the body of the device which is in the form of an elongated tube having secured thereon adjacent one end an ordinary figure 8 handle 2 by which the instrument may be inserted and withdrawn. Adj acent the opposite end of the body there is rigidly secured a limiting sleeve 3 against which the inner end of. the tube to be inserted is adapted to abut, the tube being inclicated at l.

Slidably mounted in the tubular body 1 is the operating rod 5, provided at its inner end with the spaced collars 6 and 7, between which is journaled the upper hub 8 of the adjusting nut 9. This nut is provided with a lower hub 10 which is threaded on the end of the tubular body and both hubs are connected together by diametrically opposite wings which facilitate the rotation of the nut and thereby the adjustment of the rod 5.

The outer end of the tubular body 1 is bifurcated and located in the bifurcation are a pair of jaw members 11 and 12 recessed on their inner sides adjacent the inner ends thereof so as to receive the reduced outer end of the operating rod 5. A pivot pin 13 connects the outer end of the rod 5 with the jaw members and permits the separation of their outer ends for a purpose to be hereinafter described.

The jaw members 11 and 12 are each provided with a diagonal slot 14 formed in and partially extending across an intermediate portion of their bodies, and passing through said slots 1 1 is a pin 15, keyed in the bifurcated end of the operating rod. Vhen the nut is screwed up on the threaded end of the body the rod 5 will be shifted in the body and will move the jaw members outwardly, the cam inner walls of the slots 14 acting against the pin 15 and causing the jaws to separate at their outer ends, as will be readily understood.

In the operation of the device a tube 4 is placed on the body with its inner end resting against the sleeve or collar 3. The jaws are slightly expanded to hold the tube against displacement and the instrument inserted in the vagina, pressing firmly to force the tube well into the uterus. The jaws are then fully expanded which separates the legs, thereby firmly holding the tube against displacement. The jaw members of the instrument are then collapsed by a reverse of the nut 9 and the instrument withdrawn. 7 With an instrument of this character physicians having little or no experience in the use 01' these tubes may apply the same without fear of injuring the patient.
