" Uni'rED sT FnnDinANno canso, :f:
subject ofthis application relates more par .ticularly to urethroscopes or analogous tnbular instruments adapted to' be inserted into the urethra or other channels, said instrument beingl provided at its'lower or clistal end with means for temporarily dilating' the urethral or other passage, and as employed by physicians for the 4purpose of making visual examinations as Well as treating the urethral channel or its'oavities and to'facilitate the use of other instrameints-in the urethral passage or other` channe s. l f
There' are still disadvantages or tions to instruments or, nrethroscopes of the character fabove referred to; that is to say, they support a front eover to close the outer endlof the central 'tubes passage in the act of irrigating anda fiat-flange with a gutter to collect. the' Waste-liquid iiowing back he tween the outer tube :and Wall of the pas sage during the irrigation, the result beine; achevek only closed the bore of the centrati tubawithout controllihg the act of irrigatving, as the waste liquid has free egress between the outer tube and passage and out throughI the gutter. The benefit of controlling .the act ofiirrigating as Well as otherl operations, is lost and the discomfort of the patient,by forcing thelliquidto flow among the inter-spacesof the dilating ele-- mentsof-the instrument against the Walls of the channel is increased, the act of dilating atthe distal end of the dilators causing the retraction of tissues back of the coneshaped cavity', tightening upon the tube proper andpreventingthe reflowing of the liquid. The tibe` containing' the electric .Wireiintheri'nner tube obstructs the free use ofthe auxiliary telescope and other inf struments and is insanitary. The electl lampbulb being naked isvery objectionL september v12, 191i, rt/e1* end the telescope is liable to catch on the i* ner end of the tube and prevent the insertion of the telescope and linally the`locat-ion oi the short arms on the Adilater arms forms a clogxed area at their sides which is objectionae e on account of examinations and cti er .perations construction ol the said urethroscope whereby a more simple and comparatively less expensive self-'contained instrument or "etln'osccpe is produced and in which the activant-ages or objections above referred e wholly eliminated.

A rubber inlet tube 41. leading from a source of fluid supply, not shown, is secured te the inlet pipe 18. and a rubber outlettube 42. when used, is secured to the outlet pipe 38. and extends downward to a receiving recap# tacle, not shown.
`The electric light bulb 14. is entirely and permanently inclosed in a metal casing 43. having an opening or window 44. through which the light shines and a loclting'firojec` tion 45. One et' the light terminals is attached to the metal casing 43. and the other terminal at the Contact point 4G. A lamp clip 47. having a longitudinal slot 48. is secured longitudinally to the inside of one ot" the dilater arms 11. and the lamp is detachably secured to the dilater arm by inserting or pushing the lamp through the clip 47. and then turning the lamp so as te brinfr the projection 45. against the innerA end o. the clip, as shown in Figs. 2. and 5. A tube 49. is secured to or may be embedded in the iii-- nel` face of the dilater arm 11. An insulated, Wire 50. is secured in the tube 49., one end 51. of the bare wire beingI bent into Contact with the contact point 4o. on the electric light bulb 14. and the other end of the bare wire terminating in the end 52. at the hinge joint of the dilater arm. An insulated wire F53. extends inward from a battery, not shown, through the boss 20. and the longitudinal roeve 21. `and'terminates in the bare end 54.
he bare ends 52.. and .54. f forni contact points which come into contact and close the circuit when the dilater arms are opened.- A Wire 55. extends` from Vthe battery, not
