Near the extreme forward end of the telescope tubelO I provi'de an objective 14 which is preferably arranged in a lateral fenestra and commands a lateral andsubstantially conical field of V vision. The extreme tip of the telescope tube constitutes a lamp-accommodating extension 15, the lamp 16 being mounted therein in the usual manner and being electrically con-' nected with the terminal 13 by-Lleads not shown in the drawings. 7 v

Alongside of the tube I -provide a catheter'tubel'l' which is also substantially circular but which is integrally formed uponthe tube 10 in such close adj acence thata portioniof the circular cross-section is sliced oil as shown most c-leailyin Figure 2. Stated otherwise, the conjoint cross-sectional config uration of the elongated hollow member I formed of the tubes 10 and 1-7, is definedby two circles slightly overla oping. This con-; figuration might alsojbe dehned-- as beinglsubstantially elliptical with a medial depression :tormed. on each of the longer sides of the preferably. immediately behind the lamp exq the; enlarged rear end' of the .tube 10. Over the extreme rear or inlet end of the tube 17 Iprefer tof'provide airesilientsleeve ellipse. .The sealed' and attenuated as at 18 and is, caused, to mergein a smooth and gradualm'anner with the forward portion '01? the tube,l0,

Pet-cocks 23 of Twelllniown Q'character control these inlet and outlet openings,

The main fea tures of ny: present inventicn will-be most clearly appreciated up on refer ,ence to' Figures 2-6.. The objective. off the -telescope tube commandsa lateraland conical field o'f visionsubstantially as; indicated,

. that 'cystosc'opes oflargen siz'ehave.v custom:

arily been; Iprovided with the catheter tube arranged 5 above the telescope tube, thereby. we he e-the eeslene directly extreme forward tip of the tubell is" I 'wnifp iat" dutf from the front, into thefield of vision. The proper deflection of the catheter has in such cases been accomplished by suitable mechanical deflectors or the like controllable from v the. rear of the instrument as a whole, In accordance with my'present invention the catheter tube is arranged alongside oi the telescope tube so" that the axis thereof and the axis ofthe telescopetube 'lie in a plane whichis substantially perpendicular to the axis of the lateral field of vision, as distinguished from a planecoinciding or parallel to the-fieldor vision axis.

As a result of this arrangement, most clearly illustrated in Figure 5, I am enabled to provide the outlet fenestra of the catheterf tube lTalmost in its entirety within the bounds-of theldepression formed on one of the longer sides of the elliptical cross section. This fenestra 2-1 isclearly shown in Figure 2 and it is to be noted that it lies substantiallyv in the same plane, as the obj ective 1 1 ofthe telescope tube. The fenestra 2e is arranged adjacent to the. objective 11 1 but slightly behind tlie'latter, as seen most clearly in Figure 6, and facesthe field of vision, whereby the catheter enters the latof from the front thereof,-

7 To facilitate the proper: guidance and curvinglof the eforwardlendi of the catheter as-it emerges from the catheter tube 17,1

providean inclined abutment or surface 25 immediately behind the forward sealed tip 18 of thecatheter tube. This surface lies substantially in. a plane perpendicularto he dot and dash depicted catheter 22 of Figure .2, and attention is specifically di-.

iirwliich Figure rected was direction 31s taken.

v As m nt :the foregoing arrangement, the lateralifield of vision is not only e'llicient 1y illuminated but the catheter tube iseilec tively .guidechobliquely toward the axis tliereof'without the necessity for the employment of any' mechanicaldeflecting medium,

L'The extremely advantageous .i cliai' actere. istics of instrument Will no w be. more fully understood. {In Figure?

This slicin'g fof oneportion ofthe catheter tube to provide the cross-section of overlapping circles previously 1 mentioned 'liasf the further advantage of providing space for irrigation purposes; It is to be" 'notedthat the "inlet and outlet openings controlled bythepet-cocks 23f'are arranged along the small .axis of the ellipticalv crosssection. Theseinletand outlet-'openings are arranged clo selyad'jacent to the. medial partition' 27 constituted of the inner portion of the telescope tube 10, Accordingly, the catheter tubal? may be satistactorily employed at one and; the same 7 time for pun poses of operation and also for-purposesiot irrigation. The resilient sleeve 21 serves to seal therear end of the catheter tube'to allow such irrigation to be carried into effect.

minimum size and 'maximum' smoothness, and which nevertheless renders feasible the examination and treatment of body cavities, and particularlythe bladder, in as efficlent a manner as hasheretofore been carried out by instruments of larger size and greater. complexity It'will be understood that the tube 17, referred to herein and in the appended claims as a catheter tube, is

not necessarilyrestrictedto this use but may accommodate operating "instrumentalities'of any suitable flexible character.

Furthermore, it Wlll be seen that changes trated for the purpose of explainingj the nature of my" invention may be made by those skilled in the art without departing from the' spirit andscope of the invention asexpressed in the appended claims.
