To aZZwhom it may concern:
Be it known that I, ERNEST M. PISTOR, a citizenlof the United States, -residing;at Dundee, Kane County, Illinois, have invented certain new and useful Improvements in Gauze-Packin Devices, of which the following is a speci cation.
These improvements relate to means for packing gauze into a wound or body cavity as part of a surgical or therapeut cal operation.
The medical and surgical professions are well acquainted with a form of gauze packer which consists of a relatively long tubular member having a long slender rod or feeder within it, the front end portion of the rod being provided with a pair of diverg ng prongs, its other end having ahead or enlargement which may be grasped by the hand. In the operation the old form of device mentioned the tubular member is grasped by one hand, the end of a strip of gauze in roll form is impaled upon the prongs, and the pronged end of the feeder with the gauze secured thereto is then nserted in the rear end of, the tubular member and pushed in as far as it will go. The
feeder having the pronged endis then re to be applied as a packing." The tubular member must then be held with one hand while the gauz is being inserted, and subsequently so long as the feeding operation is continued, through the movement offthe other hand. Various objections to the older form of device areencountered in practice, among which may be mentioned the difficulty of holding the instrument steadily with two hands while performing the packing operation, the disadvantage of having both hands engaged during that operation, the presence of a, roll of gauze lying loosely somewhere in the vicinity of thespecific place of operation, the twisting of the gauze or the necessity for careful watching of, it to prevent twisting while being fed through the device, importantly, the fact that the gauzeis con and by'its being handled during the feeding taminated by its rolling and tumbling about operationas well as at the time-of insertion into the instrument, and importantly also, 2
unless the operator is exceedingly careful in the back-and-forth motion of the feeder the through, in most cases necessitating a with drawal of the gauze already packed andthe beginning of the operations anew. This 1amm1ng of the gauze within the tubularv member occurs chiefly when the feeder is re tracted too far and too much of the gauze J I is thereby attempted to' be forced through.
:gauze packs and jams in the hollow interior of the tubular member and .will not go desired care of gauze-packing device. mentioned, to the end, among other benefits, that sanitary" gauze may be easily and expeditiously applied to the wound or cavity as desired, with a notable reduction of discomfort to the patient and with improved facility of operation andsatisfaction on the part of the operator, as well as a greater measure of safety to. the patient. i
In the accompanying drawings, which form a part of this specification, Figure 1 shows a resilient rod adapted to be inserted in the device to provide a rounded end ad vantageous when applying the instrument in the body cavity; Fig. 2 is a side view of vertical longitudinal section through the device of Fig.2; Fig. 4 is afragment'of a rear i end part showing a bayonet slot; Fig. 5 is a rear end view of thedevice. v
may suitably be termed a pistol-grip. handle lOof. such dimensions and shape as to be comfortably held by a single hand of the oeratorl A tube 11 is rigidly secured uponthe handle, as by sweating it fast within the i, f
tubularupper end 12 of the handle. A'revciprocatingtubular member 13 fits for easy sliding movement within the hollow interiorof thetube 11, and a relatively 'long'tubular member 14 fits so loosely within thetube 13 the instrument complete; Fig. 3 is a medial it My improved instrument includes what},
that thetube 13 may slideiupon the inner end portion of-thetube 14:. I I Thetube 14 has secured! to it ahead 15 having anannular projection 16 which fits snugly within thetube 11. A bayonet slot 17 in thetube 11 and apin 18 on thepart 16 are adapted to lock thetube 14 strongly to the tubell when the device is in use while permitting removal of thetube 14 for sterilizing purposes or for substituting one of greater or lesser length as a particular occasion may suggest.
A downwardly extendinglug 20 upon the sliding tube 13-fits loosely in aslot 21 in thetube 11, part of the handle or frame being also cut away as indicated in Fig. 3, to permit longitudinal movement of the projection 2-0 and of thetube 13.
Upon the handle is pivoted at 23 a lever having afinger piece 24 and anarm 25 pivotally connected at 26 to thelink 27, which link is also pivoted to theprojection 20 at 28. It is thus apparent that a pull upon thefinger piece 24 will move thetube 13 forward, Aleaf spring 30 secured to the handle and pressing against thestud 31 retracts the parts to their initial positions when the pressure is withdrawn from thefinger piece 24. v
A circulargauze housingor receptacle 33 is provided closely adjacent to the rear end of thetube 13. Its side wall has a.slot 34 through which issues a strip ofgauze 35 from the roll within the receptacle ()nesidewall 39, of thereceptacle 33 is readily removable, being held by a bayonet slot connection as shown by Fig. 5, whereby the gauze may be inserted. As noted from Fig. 2 thegauze 35 leads to an enlarged and outwardly-flared opening at 3 8, )roduced by an expansion of the metal of the tube there, and the lower half of thetube 13 is cut away at whereby there is provided ample room for the feeding of the gauze into the hollow interior of thesliding tube 13.
The rod orfeeder 42 is a piece of slender wire bifurcated and thereby provided with twodiverging prongs 43 at its front end, its rear end having the button orhead 44 withaprojection 45 extending therefrom and into the end of thetube 13, there being apin 46 on thepart 45 held in thebayonet slot 47 in thetube 13. Therod 48 of Fig. 1 has a similar head and apin 50 whereby thisrodv 48 may be similarly positionerli and held by thetube 13. V
The operation of the device is as follows:
The feeder 4-2 being removed from thetubes 13 and 14, a roll ofgauze 35 is freed from its paper wrappings and may be placed in thereceptacle 33 without its being touched by the operators hand. W'hile inthat position theprongs 43 of the feeder may be made to catch into the free end of the gauze and the gauze may be drawn so as to pass through the slot at 34. whereupon the covering lid may be placed upon the receptacle Theprongs 43 and the gauze held by them are inserted at 38 into thetube 13 and thence into thetube 14, the feeder being pushed forward its full length and being then made secure to thetube 13 by means of thepin 46 andbayonet slot 47. Thereupon, by merely holding the device in one hand the finger-piece 24 may be pulled upon by a the oackin o eration is substantiall complete, the gauze automatically feeding into thetubes 13 and 14 and without contact with any extraneous object. By cutting the gauze between thereceptacle 33 and thetube 13 and continuing the operation all of the free 'inaterial is soon packed into the bod cavity and thereupon the instrument may be removed.
It is to be understood that for inserting the device into the body cavity the rod of Fig. 1 is first inserted in the instrument whereby thehead 52 projects somewhat beyond the end of thetube 14 and forms a rounded end for this part of the device.
The instrument of Fig. 1 is then removed,
without removing thetube 14, and the gauzefeeding device is then put into operation as hereinabove described.
The device being entirely of metal and being susceptible of being readily'taken apart and reduced to smaller units is easily to be maintained instcrile condition. The pistolgrip and the arrangement of thetube 14 substantially pistol-barrel fashion upon the grip provide for an unusually adyantageous control of the device in use. The stroke is a predetermined one, and is never more than that which will result in satisfactory operation, whereby jamming of the gauze in the tube is avoided. The construction also provides the various other advantages hereinabove pointed out.
I contemplate as being within the scopeof these improvements various changes, modifications and departures from what is specifically herein illustrated and described, as
feeder extending longitudinally within said 130 tube, said feeder having means for engaging a strip of gauze to feed it forward within said tube and out of the forward end thereof with a step-by-step movement, and means for moving the feeder longitudinally with a reciprocating motion, said means including a lever operable by a part of the hand gripping said handle when the device is normally in use.
