The invention aimsto provide; :a new and improved instrument for surgica'lnsainsseparating the tonsils from the fau'ces,aand with this end in view, the invention I'GSid'BSai'iIl the novel subject matter hereinafter described and claimed, description heingaec'omp'lished by reference tokthe accompanying drawings.

F ig. 1 is an elevation looking in the mouth and showing a perspective view of the instrument. V

Fig. 2 is a perspective view of the instrument, closed.

Fig." 3 is an edge view thereof, opened. 7

Fig. .4 is a detail elevation on an enlarged scale looking in the direction of thearrow A of Fig. 2.

Fig. 5 is an enlarged detail transverse sectional view taken on line 5-5 of Fig. 2.

The preferred construction has been illustrated in the drawings and while such construction will be herein specifically explained, it is to be understood that within the scope of the invention as claimed, variations may be made.

The numerals 4 and 5 on the drawings denote two forwardly diverging handles having integral spring portions 6 at their rear ends, said spring portions having their rear ends integrally or otherwise joined to each other at the rear terminal 7 of the instrument. At their front ends, the handles 4 and 5 are provided with oblique portions8 and 9 which cross each other, the portion 8 being relatively wide and having a slot 10, while the v portion 9 is comparatively narrow and is slidably received in said slot. The springs 6 exert a force to relatively swing the handles 4 and 5 to move their front ends apart, and if desired, another spring 11 between the no handles, may be employed to aid in this operation.

Integral with and projecting forwardly from the portions 8 and 9, are two

shanks

12 and 13 which are normally disposed in close relation with each other as illustrated in Fig. 2, but upon squeezing of the handles 4 and 5 toward each other, are separated as seen in Figs. 1 and 3. The free front ends 12 and 13 of these shanks are curved laterally in the plane in which the shanks move when opening theinstrument, the end 13 being relatively widesand having arouhded terininal .14: while sthe'rend 12 is provided with a transversely .straight terminal 15. The longitudinal edges and the noundedsterminal 4S5 of the shank end .13 :are formed with acutzting edges :16. and thesha-nk end 1 2 is :beveled iatelflto provide thesterminal 15 with a cutting edge. The longitudinally concaveside elf .rtli'isishankwend '12 is preferably trans- L {convex and provided wit-h anti-slip .lpi ng teeth l8, ?wgh i le {the longitudinally eonivex :sidea 10f isai-d shank end .12 is preferably transversely straight.
