JOHN D. SOURWINE, OF BRAZIL, INDIANA.

SURGICAL INSTRUMENT.

Specification of Letters Patent.

Patented Oct. 23, 1906.

Application filed July 27,1905. Serial No. 271,437.

To all whom it 772/6711] concern.-

Be it known that I, JOHN D. SOURWINE, a citizen of the United States, and a resident of Brazil, in the county of Clay and State of Indiana, have made a certain new and useful Invention in Surgical Instruments; and I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in theart to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters and figures of reference marked thereon, which form a part of this specification.

Figure 1 is a side view ofmy instrument with the wires t contracted. Fig. 2 is a similar view with the wires t expanded. Fig. 3 is a central longitudinal section, partly broken away. Fig. 4 is a section on the line 4 4, Fig. 1. Fig. 5 is a section on the line 5 5, Fig. 1. Fig. 6 is a, section on the line 6 6, Fig. 1. Fig. 7 is a section on the line 7 7, Fig.

- 1. Fig. 8 is a central longitudinal section, on

a larger scale, of a portion of the instrument.

The invention relates to surgical instru ments designed particularly for treatment of the uterine cavity; and it consists in the novel construction and combinations of parts as hereinafter set forth.

The object of the invention is to provide a special instrument for curetting, dilating, and irrigating the womb and cognate purposes. In such operations it has been usual to employ several instruments which require independent adjustment and occupy valuable time to the detriment of the patient,

when simplicity and celerity are necessary. For instance, in uterine curetting it is usual to employ a vaginal speculum, a tenaculum, an uterine dilator, and a return-flow irrigator, and after using all these instruments the operation is often a failure, more harm having been done than good, the patient sometimes dying from septic absorption.

In operating with my instrument all that is required is to use the forefinger of the left hand to guide the point of the instrument through the vaginal cavity to the mouth of the womb, then by gently expanding the wires within the womb and rotating the same as the expansion goes on all the diseased contents of the womb-such as polypus, retained placenta after abortions or premature births, or such as occur when septic conditions spring up after a full-term birthcan be ing at one end a conoid-point portion-b and at the other end an exterior thread 0, to which may be applied a perforated bulb-nut d for the ready attachment of a flexible irrigation-tube. (Not shown.)

' On the irrigation-tube a is an elongated holder-sleeve e of less length than the irrigation-tube, the difierence in length being in accordance with the extent of adjustment required for expansion purposes, usually from two to five inches. This telescopingsleeve is provided with a tubular body part f, to the end of which is connected a swivel-nut g, which is formed with an annular groove at h to engage an interior projection or collar 7c of said body-piece, which may be secured in place by means of short screws m. The nut g is a lever-nut having short lateral arms n, whereby it can be readily rotated on the threaded end of the irrigation-tube a with which it is engaged. The body part f of the sleeve is provided with lateral holding-rings p, whereby it can be held firmly and surely in position for the adjustment of the tube aand curetting wires if during an operation. The upper portion of the body part isslotted longltudinally, as at g, the slot being long enough to allow for the movement of the indicator 8, which may be a small screw secured in the threaded ortion of the holder sleeve. On the face 0 the body part through which the slot is formed are provided scale marks, whereby the extent of expansion of the Wires can be determined. 'The engagement of the screw 8 with the slot also serves to prevent rotation of the tube a in the holder-sleeve.

Longitudinally of the instrument extend the steel wires t, usually four in number. These wires are connected to the point portion of the irrigation-tube a at one end of the instrument, and their other ends are secured to the body part of the sleeve e. These wires are of the best steel, and each two wires are 'made entire, having a bend at the point portion, as at w, the bent part passing transversely through perforations in the conoid point I), which is formed with protectingnotches u, leading to such perforations, so that there will be no projecting angular portions of the wires behind the point portion. This is further guarded against by means of a slide-ring'2 of about the same diameter as the base of the point portion andwhich is carried. by the irrigation-tube a. Near the conoid-point the tube a is provided with small perforations 2 for irrigation purposes.

The outer ends of the expansion-wires are seated'in grooves 3 of the tapering portion 12 of the body part f, which is formed with a threaded extension 3. A sliding ring 4 is located on the tapering portion '1), and this ring is driven upon this tapering portion and on the ends of the wires in the grooves thereof by means of a lever clamping-nut 5, engaging the threaded extension 3. In this manner the outer ends of the wires are firmly secured to the body part f after adjustment in its grooves of the tapered portion thereof. The wires are designed to be normally straight to the end of the sleeve e, where they are nor mally slightly bent outward in a convex form to the conoid point of the irrigation-tube, as indicated at 6. The sleeve, therefore, is long enough to extend within the expanded portion of the wires.

The sleeve e is provided with a longitudinal guide-groove 7 for sliding engagement with inward projections of the adjusting slide-rings 8 and 9 and 10, which are movable on the sleeve and which are provided with inside notches 1" to engage the expansion-wires and hold them in proper relative position. The first of these rings 8 is olive-shaped and tapering forward. Its position is at or near the end of the sleeve 0. Along the sleeve are placed the other rings to keep the wires straight along the surface of said sleeve, according to the adjustment. By means of these slide-rings the length of the expanded portions of the wires can be adjusted to suit the cavity, and the contour or curvation of the wires is easily controlled by means of the slide-rings, the adjustable irrigation-tube a, and the normal bend of the wires between their convex and straight portions. As the longitudinal extent of the expanded portion is regulated by the slide-rings and the radial extent thereof by the position of the adjustable tube a relative to the holder-sleeve the contour of the expanded portion can be readily changed to suit the cavity. As the radial expansion and retraction of the wires is efiected without change of position of the adjustment-ring on the sleeve and without relative movement between such ring and said wires there is no liability of injury to the soft parts in changing the contour of the expanded portion during an operation.

Having described the invention, what I claim, and desire to secure by Letters Patent, is-
