Application lcd September 25, 1925. Serial No. 58,579.
This invention relates to improvments in tonsil removers.
The present device relates generally to the form of the instruments now used for removing tonsils by what is known as the Sluder method.
The prime purpose of the invention is to provide an instrument or device of the above character which will enable tonsils to be removed with little or no bleeding.
A further object of the invention is that the instrument or device be provided with means whereby the tonsils removed, together with any material expressed from a tonsil during its removal, will be efficiently removed from the patients throat.
It is also an object of the invention that the instrument or device be adapted to permit tonsils to be quickly removed and thereby enable a short anesthetic to be employed when removing tonsils.
It is also within the scope of the objects of the invention that the device or instrument be compact, easy to operate, and not i subject to getting out of working order.
Other objects and objects relating to details of construction, combination and arrangement of parts will hereinafter appear in the detailed description to follow.
In carrying out my invention I provide a handle having` an elongatedv frame or stock projecting therefrom which may be extended into a persons throat, said frame or stoel; having an opening in its free end adapted to accommodate a tonsil. The frame carries a crusher bar and a cutter bar, both capable of being operated by the thumb of the operators hand grasping the handle of the device. The crusher bar *0 serves the purpose of crushing the tissue holding a tonsil to its associated throat wall; the cutter bar serves to cut the crushed tissue. The crushing` of the tissu-e prevents bleeding. I also provide a receptacle so arranged upon the end of the elongated frame or stock that a severed tonsil will drop therein together with any matter which may be expelled from a tonsil during the removal thereof.
The invention is illustrated by way of example in the accompanying drawings in which Figure 1 is a perspective view of the device showing the Crusher bar and cutter bar in normal or inoperative position.
Figure 2 is a vertical longitudinal sectional view taken on line 2-2 of Figure 1.
Figure 3 is al schematic view illustrating the principle upon which my device oper ates in removing a tonsil.
Figure 1 is a view similar to Figure 2 but showing different positions for the tissue Crusher bar and lever for operating they same.
Figure 5 is a perspective view of the crusher bar.
Figure 6 is a group view showing in perspective the elongated frame for carrying the Crusher bar and cutter bar, together with means for mounting'the lever which operates the crusher bar.
Figure 7 is a perspective group view showing the cutter bar with its removable blade, and the operating button therefor.
Figure S is a perspective view of the support for thetonsil receptacle or bag.
Referring to the drawings more particularly, 1() indicates generally a handle which may be of any desired shape. rlhe handle has extending therefrom an elongated frame or stock 11 which terminates at its outer end in a head 12 having an opening 12' adapted for receiving a tonsil. The upper side of the frame or stock 11 is preferably flat as shown at 13. The head 12 has its forward end 14C rounded as shown and said end is provided with a slot 15. The inner side of the rounded portion 14 is rough as shown at 16. The head 12 is provided with a bead or enlargement about its edge and the two side portions of the enlargement 17 each has its inn-er side formed with the longitudinally extending grooves 18 and 19, the grooves 19 being arranged above grooves 18.
Slidable upon the stock 11 is a cutter bar generally indicated by the reference character 20 which comprises a carrier member 21'and a blade 22. The stock 11 is provided with a longitudinally extending groove into which the member 21 is slidably fitted. The blade 22 is removably secured to the member 21 as shown. 1Ihe member 22 has its forward end provided with an enlargement 23a" which has a cutting'edge 23 and said enlargement is adapted to slide in grooves 18 of the head 12.
Upon the cutter bar 2O there is movable a crusher bar 23, said bar being provided at its forward end with an enlargement 2a which has a curved forward end 25 correspending to the curvature of the inner side of port-ion 14 of head 12. The enlargement 24 of the crusher bar 23 is also provided with lugs 26 which are adapted to slide in `grooves 19 of head 12.
The cutter lbar carries pins 28 and 29 which are movable in slots 30 and 31 respeci tively oit the Crusher bar 23.
The rear end of' the cutter bar 2O has a de pendingl .lug` 32 which is adapted to engage the free end of a leaf spring 33 carried by handle 10. The last named end ot cutter bar 20 has threaded therein a screw 34 which turnably supports a button 35. The opening in the button through which the screw 34 extends is suiiicient-ly enlarged adjacent the inner side of the button to accommodate a coil spring` 36. The spring 3G permits limited movement ot the. button 35 toward the associated end of the cutter bar 20. The button 35 carries a lug 38 and a spherical peripheral protrusion 39. The lug 38 i adapted to be brought to register with the associated end of the Crusher bar 23 or with the lug 32 carried by the cutter bar 20. The protrusion 39 serves to indicate the position of lug1 38 on the button 35 and to provide mea-ns for quickly turning the button from one position to another.
The handle 10 is further provided with two lugs 41 which occur at the inner end or the frame or stock 11. Each lun; 41 is formed with an opening 42 adapted to journal the ends ot' a roller 43. The roller 43 is formed with teeth or ribs 44 which may be brought into mesh with similar teeth or ribs 45 on the Crusher bar 23. The roller 43 is further provided with an elongated lug 46 which is adapted to be brought into the recess 4? in Crusher bar 23. Each end of the roller 43 is provided with an extension 47 which is square in cross section and upon these extensions there is fitted the terminals ot a lJ-shaped lever generally indicated by the reference character 48. One terminal ol the U`shaped lever member 48 is held upon its associated extension 47 ot roller' 43 by set screw 50 and washer 50 while the other terminal is held in position by a screw 51 having a knurled head 52.
The bridge portion oi the lll-shaped lever member is provided with a thumb plate 523. One ot' the lugs 41 of handle 10 may have the periphery of' its opening' 42 formed with a notch 54 to facilitate tlie positioning ot the. roller 43; while the remaining lug 41 el said handle has formed therewith aduc; or detent 55 which is adapted to move in a depression 5F formed in the end of the associated terminal of the lJ-shaped lever member 48 and serve to limit the swinging,y movement of said lever. i
The Crusher bar also carries a pin 56 which is adapted to engage the roller 43 and limit rearward movement of said Crusher bar. The pin 56 secures one end ot a leaf spring which extends between said pin and teeth 45. The spring normally engages bencath the roller 43 and maintains the crusher bar 23 upon the. cut-ter bar 20 and serves as a tension spring to hold crusher bar in open position while instrument is being' applied.
The handle 10 also carries a spring' pressed ratchet lever 58 which is Lshapcd and mounted as shown. This lever is provided with teeth 59 which may be brought to engage with a lip 60 formed upon the rear end oi thumb plate 53.
New referring to Figure 8 there is shown a sack or bag holder generally indicated by the reference character (31, and comprising a frame adapted to be fitted upon the lower side of head 12. The frame is formed with an extension 63 preferably bent as at G4 adjau cent its inner end. Adjacent the outer end ot extension 63 there is formed an opening 65. .lis shown in Figures 2 and 4 a set sere may be extended through opening, G5 and the bag holder 61 secured to the stock 11. rlfhe bag; holder extension G3 may be formed with tangs 66 which may be em ployed for further securing the same to the stoel; 11. As best illustrated in Figure 2 the upper end of a bag or sack G1 may be clamped between the trame 62 and the bottom side of head 12. The bag GS may be olf any size, shape and material desired.
ln the use ot the instrument heretofore described, the stoel; 11 is extended down the patients throat and the tonsil to be removed brought into the opening` 12 of head l2. |The operator, of course, grasps the handle 1() with one hand, and after he has properly positioned the head 12 of stock 11, the button 35 having; been previously arranged so that its lugl 88 will register with the associated end et the crusher bar 23, he then with his thumb pushes forward upon the botton 35 which will force the Crusher and cutter ar iorward. The Crusher bar should be moved forward until the teeth of roller 43 engage teeth 45 on Crusher fbar 23. At this mon'ient the ofl erator may swing downward lever 48 and force the Crusher bar 23 turther forward. The lever 48 may be brought to a position 'for engagemnt with ratchet le- 58 and then locked against movement as illust-rated to advantage in figure 4.
New referring to Figure 3, it will be oliserved the Crusher bar 23 has been advanced to crush. the tissue holding the tonsil to the throat wall. fit this period the operator should rotate the button 35 to bring its lug' 38 into register vith the cutter bar lus` 32 and then push lorwa d upon button whereby the cutter bar 20 will be forced forward and sever the cruelle'Y tissue holding the tonsil to the throat wall. rEhe tonsil and all matter escaping therefrom will drop into the bag 61 and the instrument .can non* be withdrawn from the patients throat, or
llllfi if desired the remaining tonsil may be removed in .themanner heretofore described. It will be noted the individual forward movement of cutter bar 2O will bring lug` 32 into engagement with spring 33 and depress saidj spring. It is therefore apparent that immediately upon releasing the cutter bar Vthe same will be retracted toit-s normal position with respect to Crusher bar 23. Also by releasing lever 48 and swinging the same upwardly the orusher bar and cutter' bar are brought to their original or nonoperative position, and the device is: ready for proceeding` with the removal of another tonsil. l
It is to be here pointed out that the device can be easily operated, and from the description given it is apparent the samecan be employed for removing tonsils in an exceedingly rapid manner. Also it will be observed from the structure of the device that the same can be easily dissembled if desired. rI`he blade 22 can be removed without diiiiculty and likewise the bag 6l.
