BENNARD T. PARSONS, OF VVRlGHTSVILLE, NEW JERSEY, ASSIGNOR TO THE SURGICAL DILATING SYRINGE COMPANY, OF NEW JERSEY.
DlLATlNG-SYRING E.
SPECIFICATION forming part of Letters Patent No. 393,580, dated November 2'7. 1888- (No model.)
To all whom it may concern:
Be it known that I, BENNARD T. PARSONS, a citizen of the United States, residing at \Vrightsville, in the county of Camden, State of New Jersey, have invented a new and useful Improvement in Dilating Syringes, which improvement is fully set forth in the following specification and accompanying drawings.
My invention consists of a dilatingsyringe having novel means for operating the blades thereof.
It also consists of a novel sponge holder.
It further consists of novel means for securing and releasing the sponge or swab holder.
It also consists of the combination of other parts, as will be hereinafter fully set forth.
Figure 1 represents a side elevation of a dilating-syringe embodying my invention. Fig. 2 represents a section of a portion on line as .r, Fig. 1. Fig. 3 represents a side elevation of the inner portion of the sponge-holder. Figs. 4 and 5 represent sections respectively on lines y y and z 2, Fig. 2.
Similar letters of reference indicate corresponding parts in the several figures.
Referring to the drawings, A represents two spoonshaped blades, to which shape, however, I do not limit my invention. The lower or inner ends of said blades are hinged to ears 1 on a threaded collar, 2, the latter freely encircling a sliding sleeve, 3, which is fitted on a tube, 4. One end of the sleeve 3 passes through the eol lar 2 and has pivoted to it an end of each of the arms B, whose other ends are pivotedto the blades A. The opposite end of said sleeve 3 has a shoulder, 5, and is freely encircled by the head 0, which is held in contact with said shoulder by means of a nut, 6, it being noticed that the head has a rim, 7, which is interiorly threaded and engages with the threads on the exterior of the collar 2, so that as the head is rotated it also moves in longitudinal direction, and thus imparts motion to the sleeve 3, the efiect of which is the operation of the arms I and consequent opening or closing of the blades A.
A portion of the tube 4 is between the blades A and sustains the sponge or swab holder or arm D,whose inner end has a neck, 8, and head 9, said neck freely entering a recess, 10, in a nut, E,which is screwed to the end of the tube 4, and said head 9 engaging with the under wall of said recess, said neck, head, and nut thus being connected to the said tube 4, so as to be adapted to be operated therewith.
\Vithiu the tube 4 is a tube, 1l,whose inner end is internally beveled,so as to ride against the outer face of the head 9 of the holder D, it being noticed that said head is bent inwardly or stands obliquely, so that the beveled end of the tube 11 may enter between the tube 4 and the head 9, as will be seen in Fig. 2. The outer end of the tube is screw-threaded and engages with screw-threads on the contiguous end of the tube 4.
On the tube 4 is a shoulder, 12, whose ends rest against the shoulders 13, formed on the end of the sleeve 3 adjacent to the pivots of the arms B, so as to prevent rotation of said tube 4, and consequently of the sponge-holder.
The operation is as follows: \Vhen the blades are to be separated or spread apart, the head 0 is rotated in the proper direction, whereby as it screws on the collar 2 it receives sliding motion, which latter is communicated to the sleeve 3, owing to the connection of the part-s due to the shoulder 5. This operates the arms B in such manner as to throw out the blades A, and thus distend the canal into which they. are introduced. The blades having been opened, the sponge is partially rotated by means of the head G on the outer end of the tube 11, so as to wipe or cleanse the uncovered portion of the wall of the channel. The blades are then closed and turned in the passage,when, being opened or distended, another portion'of the passage is subjectedto the action of the sponge. hen the head 0 is rotated in opposite directions, the arms B are drawn in, thus closing the blades A. As the sponge- 9o holder prevents the blades from closing to full extent, it is necessary to release said holder.
For this purpose the tube 11 is unscrewed, whereby its beveled end leaves the head 9, so that the holder is free to swing inwardly and 5 thus yield as the blades approach.
F represents a tube which is connected with the pump or bulb G of a syringe and passed through the tube 11 and nut E, so as to have its discharge end between the blades A, by
which means fluid may be injected into the canal or affected part.
\Vhen the tubes 4 and 11 are unscrewed,they may be removed in opposite directions from the sleeve 3, the; tube F having been previously withdrawn. Thesleeve 3, having its inner face polished, now becomes a speculum, for evident purposes.
Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is
1. In a dilating-syringe, opening and closing bladespivotally secured to a collar, a sleeve within said collar having pivotal arms attached to the blades, and a head having a screw threaded connection with said collar and bearing against said sleeve, said parts being combined substantially as and for the purpose set forth.
2. The sponge or swab holder having a neck and head and the holdingtube and recessed nut therefor, in combination with a tube inclosed in said holdingtube and having a beveled end which engages with the head of said sponge-holder, the parts being combined sub stantially as described.
3. In a dilating-syringe, a rotatable and sliding tube carrying a sponge or swab holder and provided with a shoulder which engages with shoulders on the syringe for locking said tube, substantially as described.
4. A dilating-syringe consisting of opening and closing blades pivotally attached to a collar and by arms to a sleeve within said collar, ahead connected to said collar for operating said blades, a sliding tube within said sleeve, a swab-holder secured within the inner end of said tube, and an inner tube with outer end having screw-threaded portion for engagement with said outer tube and a head for operating the said tube, said parts being combined substantially as and for the purpose set forth.
5. In a dilatingsyringc, opening and closing blades pivotally attached to a collar, arms pivotally attached to the inner walls of the blades and to a sleeve, the latter moving within said collar, a head bearing against said sleeve and having a flange interiorly threaded engaging with said collar, a nut working on a screwthreaded end of said sleeve and bearing against said head, said parts being combined sub stantially as and for the purpose set forth.
