Vbv menait@ 1y 1,003,232, dated September y12, 19,11, 1,Q&, 28, ated November 1,2, 1912 'and' 1,139,015, dated May 11,l9 15.

.een
The length and diameter of the outer tube 8 may be of any suitable dimensions, suoli tor example as will permit the instrument to be Yhead 14 having internal screw-threads 15 and a radial screw-threaded hole 16 in is aknurledheaded screw 17. n
The inner'tube 9 has an externally screwwhich threaded head 18, a collar 19, a slight lon? gitudinal groove in which the innerend of they screw 17 has a sliding fit, and which allows longitudinal movement of the inner tube 9,. but prevents the inner tube 9 from turning on Aits axis when the innerend of the screw 17 isv in the groove .20. The inner or dilater end of the inner tube 9 has a series, preferably four, et bayonet joint slots 21,21, as shown in Figures '2, 5 and 6. rThe dilater arms 10, 10, may be straight orv curved and when closed form a cone shaped apex or inner end on the instrument. Secured to each of the dilater armsY 10, 10, is a wire operating member 22 having an end 23 secured te the dilater arm 10 by riveting or other means, an inclinedlportion 24 in a bayonet joint slot- 21 in the end or" the inner tube 9, and a straight portion 25 terminating in an end 26 secured to the dilater arm 10 by riveting or other means, as Vshownin Figure 2. j
The sight and lamp member 12 is in the form of a short cylindrical body member 29 having a bevelled inner end portion 30 which merges into aninternally Screw-threaded end 31, which screws over the externally screw-threaded head end 18, ofthe inner tube 9 and secures vthe sight and lamp meinber 12, to the inner tube 9. This body member 29 also hasV a lamp socket 32 in which is an electric lamp33, which is electrically connected to a source et electric energy,net shown, by wires, through an opening 34 in the body member 29. The Aouter end of body member 29 also has external screwthreads 35 and a reflectorv 36 is placed back of the lamp 33 on the bevelled end portion 30, as shown in Figures 2 and 4. A dished sight member 37 i-s constructed to have an internally screw-threaded flange 38, which screws over the external screwthreads 35 of the body member 29, a central sight tube 39, which lextends into the body member 29 vAll of t e parts of the instrument can be made of Grerman` silver vor other suitable metal or material.
By means of this improved construction the urethroscope when inserted, er in use, may be easily and quickly Ymanipulated so as to accurately andV positively loperate the dilater arms` simultaneeusly'to the desired may be closed or moved inwardly so thatY they will clasp any body located between them, and the instrument can then be einployed like a forceps to withdraw suchrbody from the previously dilated channel. j
In th-e use-of 'my improved Vurethrescope, the instrument first sterilized isinserted into the urethral passage or other channel to the extent desired followed by turning the operating member 11 to the right ther-ebycorrespending-ly moving the inner tube V9 lengthwise, when the'inner edges of the bayonet joint slots 21, 21 in the end of the inner tube'.
9, engaging with the inclined portions 24,v` 24 of the wire operating members 22, 22, will cause the dilater arms V10, 10 to expand Vor open, as shown indotted lines in Fig-V ure 1. The lamp casing 12 is new screwed upon the section 18 of the inner tube 9 and the electric lamp .33 is lightedby closing a switch, not shown. Light from the lamp 33 isfnow reiiected from, the reflectorV 36 onto the reiiectort() and the light from the reflector 40V is thenk reiiected into and through the inner tube 9 and onto the expanded parts thus acted upon. The physician may then make a visual examination or inspection of the thus acted upon parts by loekingthrough the sight tub-e 39. V
At the completion of the` operations the" lamp 33 is put out, the sight and lamp mem-' ber 12 is removed from the inner tube 9, by unscrewing it, vthe operating member 11 is turned to fully open the dilater arms, the screw 17 is Withdrawn from the greov-e 2O in the inner tube 9 and such inner tube is then given a partial turn to the .left by grasping the outer end 18. This last operation brings the inclined portions 24, 24, ot the wire operating members 22,22 into the open end et the bayonet joint slots 21, 21, and the innertube 9 may now be drawn entirely out of thek outer tube 8 byunscr-ewing the operating member 11 from the head 14.- Avll `or" the parts of the instrument are thus easily separated and may now be thoroughly cleaned or sterilized,tor sanitary reasons.
n Lea-1,7m
By the use of my improvedconstruction j in urethroscopes, the instrument is easily and quickly'taken apart forfsterilizingnthe parts-and for minor repairs,the sight and the act V4of irrigating is more sanitary than heretofore and a more perfect urethroscope 1s.4 produced, than has previously been devised.
If desir-ed, the improved instrument may be employed for irrigatingthe channel in Vwhich it is inserted. For this purpose the sight and lampmember 12 is detached and the irrigating member 13, illustrated in detail in Figure 7, substituted therefor.
rIhe irrigating member 13 consists of a cylindrical head member 41 having an internally screw-threaded inner end 42, which Screws over the externally screw-threaded head end 18 of lthe inner' tube 9, an internally screw-threaded outer end 43 and an outlet tube 44 to which may be connected a rubber tube, not shown, for carrying away v the remedial or other fluidsused in irrigating. Screwed into the screw-threaded outer end 43 in the outer end of the head member 41 is a screw-threaded plug 45, having external screw-threads 46, a knurled flange 47 and an enlongated central tube 48, the inner end 49 of Which extends preferably into the dilator end of the instrument, when inruse, and the outer end of which terminates into an inlet tube 50, on the outer face of the plug 45, as shown in Figure 7*. A rubber tube and bulb, not shown, may be secured to .this inlettube 50, for forcing remedial or other fluids through the tube 48. When irrigating, the remedial fluid flows or is forced through the central tube 48 to the enlarged portion of the urethra, asV indicated by the arrows c, c, in Figure 7 and then it flows back between the central tube 48 and the inside of the inner tube l9, through the head member 41 and then out through the outlet tube 44, as indicated by the arrows a, a, in Figure 7 The remedial liquid is thus kept entirely out of contact with the external portions of the body` and by this new construction very little if any enters between the outer tube 8 and the inner tube 9.
