SURGICAL INSTRUMENT.

Specification of Letters Patent. Patented Nov, 22, 1921,

Application filed April 13, 1920. Serial No. 373,520.

To all whom it may concern.

Be it known that I, AAREIEL E. GoonLon, a citizen of the United States of America, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have in- Vented certain new and useful Improvements in Surgical Instruments, of which the following is a specification.

This invention relates to certain new and useful improvements in surgical instruments of that class designed. for insertion into the natural passages, organs and cavities of the human or animal body for inspection and for the removal of foreign matter and bodies and for the treatment of the body or other similar surgical operations.

The chief improvement consists in combining a tube orbarrel for the ordinary uses for which instruments of this class are used, with a jaw or blade at the outer extremity of the tubeso constructed that the jaw and tube combine to grasp certain objects and at the same time vision of the object is maintained. The same principle is involved when, by adding certain and special knives at the outer or tip end of the tube, certain surgical operations may be performed, and tissue can be held so as to be inspected, diseased tissue and tumors or other growths can be removed for examination and other purposes.

While the improvements forming the subject matter of my invention may be applied to any tube of suitable size and shape for the insertion of the same into passages, etc, of the human body, and for the removal of bodies, etc., from any cavity, opening or passage of the human or animal body for the purposes stated, the invention will be described in connection with a bronchoscope, designed to facilitate inspection and particularly the removal of foreign bodies from the human bronchi, as the instrument is illustrated in the accompanying drawing, in which- Figure 1 is a side elevational View of a bronchoscope consructed in accordance with the present invention and with its parts in their normal position, the handle being partly broken away,

Fig. 3 is atop plan view of the device shown in Fig. 1, I

Fig. 4 is a transverse sectionalview'taken substantially upon line IVIV of Fig. 1,

Fig. 5 is a plan view of the jaw carrying Fig. 1, parts being broken away and parts strip,

Fig. 6 is an elevational View of the outer end portion of the device shown in Fig. 1 with the jaw raisedor in the first step of its movement,

Fig. 7 is a view similar to Fig. 6 with the jaw and associated members in the second step of their movement.

Fig. 8is a view similar to Fig. 7 with the jaw in its third step of movement or first position in closing, and

Fig. 9 IS a longitudinal sectional view of the outer end portion of the bronchoscope with a modified form of carrying member 7 for the jaw.

The four positions of the jaw disclosed in Figs. 1, 6, 7 and 8 are represented for convenience of description by showing the four stages of opening and closing of the jaw.

Like reference characters indicate corresponding parts throughout the several views.

Referring more in detail to the several views, the present invention includes a long tube or barrel 5 which is open at both ends and has a suitable handle 6 rigidly fastened on one end thereof so that clear vision may be had through the tube at all times. A sheet metal strip 7 of the. form more clearly shown in Fig. 5 is slidably disposed upon the upper portion of the barrel 5, and this strip 7 is arch-shaped in cross section as clearly shown in Fig. 4, while the forward end of said strip is forked and apertured to provide a pair of cars 8 to which the jaw 9 is hinged adjacent the inclined forward end of the barrel 5. The rear end of the'strip 7 is slid-ably extended through aslot in the handle 6, and at set screw 10 is threaded into the handle 6 so that its inner end bears upon the upper face of the adajcent portion of the strip 7. The office of the screw 10 is to adjustably resist movement of the strip 7 longitudinally relative to the barrel 5 as will presently become apparent, and said and this'rod 13 is pivotally connected at strip 7 is provided with a head 11 upon its inner end so as to prevent the strip from moving forwardly through and out of the slot in the handle 6. The barrel 5 is, provided with a suitable shield 12 within which the forward portion'of the strip'7 slides so that contact of the strip 7 with the walls of I the passage ofthe human body isiprevented.

I A rod 13 is slidably disposed Within a--lon---- latitudinal rem v lermv n "the, pp

portion of the barrel 5 beneath the strip 7,

its forwardend to the ,jaw 9 as atg15 and "has its inner end bentupwardly so as to freely extend through the longitudinal elo-ngated slt'16 provided in theljaw carrying; I strip 7, and to extend through a perforation in theQfinger piece or slide 17 which is n 19untedfjupon the barrel 5" adjacent the handle 6 whereby, when said slide orfinger piece is moved longitudinally of the barrel 1 '5 similar movement is'imparted to the rod 1 13.

When fthe finger piece 17 is moved forwardly, the controlling rod 13 is caused to nove forward so as to .swing'the jaw 9 jaw is accomplished by the same "principle or: general operation but the order ofmove .ment lsl'eYBISBCl. In other words, for;closmg the aw, the finger piece 17 is (inwardly or rearwardly, upon the barrel 5 40; rear inner. end of the rod 13 engages the inner end wall of the slot 16 of the strip 7 so as to cause a pull upon the controlling rod-13 and lower the jaw to the position of Fig. SwWVhen this takes place, the angular and causes the Llatter, to slide rearwardly until the jaw is returned to its normal position as shown in Fig. 1. The controllingrod-l3palways movestforwardly or backwardly 'before the sliding piece or strip 7 moves, due to the friction on said controlling en 5 o a,

ro'di18being less than that on the sliding a piece or strip 7 This-greater friction. upon the strip 18 illustrated as obtainedby means of the screw but other means may b utilized, on such friction may be obtained by. placing the thumb oringer on strip 7.

The finger piece 17,includes a tubular body having fingerreceivingrings '18, rigidly connected thereto and extending upwardly and downwardly therefrom; The'body of the fin -er oiece 17 is orovided with an eni D v n w 1 I largem'ent 19 on 1ts underslue through w hlch extends a radial slot 20, having a locking slide 21 disposed to slide upwardly. and downwardly therein for engagingtherough- 1 ened upper surface 22 with the under surfaceof 'strip'23, or for disengaging said face The light is illuminating the interior oftube and pasmoved from the strip 23 as desired, the strip 23 being soldered or otherwise fastened at the underside of the barrel .5 within the finger piece 17 to the tube 24'. The tube 24: is rigidly fastened to the under side of the l barreh an d opensatits distal end into the tube 5, alongside and adjacent to the apervture- 32 of the drainage tube 31. The relative position of the light and the distal opening of drainage tube is shown in Fig. 2 at '32 and 25, the perforation 32 being' adjacent light 25 fore/securing perfect drainage of region adjacent or near the light. Thus as will be seen, the upper and'lateral vsurface'of-lightglobe is adjacent to the opening of drainage'tube and the lighttrays emanatefromthe bottom of the distal end of tube 5. V V utilized for the i purpose of sage in which the-instrumentisused, and

the wires from the'lamp 25 which are broadly shown in Fig." 1 at 26, --'are extendedlrearwar'dly through the tube 2 L to a- 1 suitable source of electricity'. This source of-electricity may reside in theordinaryform of dry cell battery which may beca'rried in-the ocket ofthe operator-and flexibly connected to the bronchoscope. a

'The locking slide 21'is of suchlength as to extend-below the enlargement 19 of the finger piece 17 and is provided in its lower end with; atraji'isverse inclined elongated slot 27 into which extends the laterally extending pin 28 -w-hich' is rigidly carried by a finger operated lever 29, the lever 29 being pivoted as at 30-to the finger piece 17 so as to be swung forwardly or rearwardly as des red As the slot 27 1S inclineddownwardly, and .rearwa'rdlyit will be. seen that when the lever 29 is'pressed rearwardly, the

slide 21 is caused to rise until its face 22 en-' gages the strip 23, andthe finger piece 17 is thereby effectively held against movement onand r'elative to the barrel 5. sothat the jaw 9 is effectively held and maintained in anyof its positions I whenafound. necessary. By this means, the operator is on abled to obtain a strong grasp on any object which n'iay be within the grasp of thejaw 9.

His somewhat usualin the present class of devices to place a drainageltube atthe top of the barrel 5, andthis is quite impractical with thepresent construction and somewhat undesirable; I place; :this drainage tube alongside of the tube: 24; as shown at 31 and thereby make use of the space formed vby the joining of the tube 24 to the barrel 5. The drainagektubecommunicates at its forward end with 5116 111061101 oftlie barrel 5-by means of a-penforat1on 32 provided in the latter at its forward end, and adjacent to the upper surface of'the light bulb 25, both drainage tube Bland light carrying tube 24 l opening Jadj acent and within 1 the forward end of barrel 5, The drainage tube end of the barrel 5 and has a set screw 35 threaded therethrough so as to engage the barrel 5 and offer frictional resistance to the sliding movement of the sleeve 34. It is to be understood that the construction of the bronchoscope will be substantially iden tical in Fig. 9 as in the other figures with the exception that the strip 7 is eliminated and the sleeve 34: is substituted in its place.

It will be understood that the jaw 9- may be given simple opening and closing swinging movements from the position of Fig. 1

to the position of Fig. 6 and then back to the position of Fig. l by threading the set screw 10 into firm engagement with the strip 7 or the set screw 35 with the barrel 5 when found desirable.

From the foregoing description it is believed that the construction and operation as well as the advantages of the present invention will be readily understood and appreciated by those skilled in the art.

It is of course to be understood that minor" changes may be made in the form, combination and arrangement of the various parts herein specifically set forth without departing from the spirit and scope of the invention as claimed.
