Improvements in Appliances for Illuminating Cavities of the Human
Body and Performing Operations therein.
I, CARL BOLLÉ, of 119 Plymouth Grove, Chorlton-on-Medlock, Manchester
in the County of Lancaster, Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
My invention consists in an improved arrangement of a cystoscope or the com-
bination of operating tools with an ordinary cystoscope, so that the instrument
serves not only as has hitherto been the case for illuminating cavitives in the
interior of the human body in order to ascertain the existence of diseased membranes,
but serves at the same time to perform operations at the respective spots while they
can be observed.
On the drawings appended hereunto
Figures 1 to 3 show a longitudinal section, front and side view of my improved
cystoscope, while
Figures 4 to 7 show the novel parts of the instrument in cross-section and two
working positions.
The cystoscope consists of a tube B fitted with the knob A and having at its end
the bend or beak D into which the little lamp D' is bedded. The conducting wires
for this little lamp are arranged in the usual way and the instrument constructed so
far in the ordinary manner.
The tube B is surrounded by a second tube B₁ containing a slot at its
front end into which slot a projection con tube B enters and guides tube B',
and the latter is made shorter than tube B so that it can slide to and fro on said
tube B.
At the front end of the tube the tool for performing the surgical operation, such
as nippers, scissors, pincers, hook or similar tool, is fixed. On the drawing a pair
of scissors is shewn as an example how these tools are to be arranged.
The scissors F move on a pivot f fixed to a lug projecting from the end of
tube B and fitting closely to the inner tube B, so that when the tube B' is drawn
back, the scissors are likewise drawn back, and when the tube B' is pushed forward,
the scissors are also pushed forward and brought close to the beak D of the tube.
This close fit of the tool is essentially necessary in order to prevent injury to the
patient when introducing the instrument into a cavity of his body. The scissor
legs F are connected by the toggles e e with the rod E, which passes between the
two tubes B and B' and terminates at the back end of the instrument in a handle E
guided in a slot B2 of the tube B. By drawing back or pushing forward the rod E
the scissors F can thus be closed or opened.
For performing an operation the cystoscope is inserted into the respective cavity of
the human body, the little lamp D' lit up in the well-known manner and the tube B¹
drawn back, so that the scissors which lie close to the beak D of the tube Bas
shewn by Figure 6 while the instrument is inserted, are drawn away from the same
and take the position shewn by Figures 1, 2 and 3. The lamp D' is then moved
about in the cavity and if any diseased parts are discovered requiring treatment by
cutting off excrescenses or such like portions, the scissors F are opened by drawing
back the rod E (Figures 4 and 5) and so moved that in closing the scissors by
drawing back the rod E (Figure 2) the desired operation is performed.
During the operation the diseased part remains constantly visible to the operator
who has applied his eye to the knob A and sees through the cystoscope the diseased

page_text: part illuminated, and as the drawing back of the rod E is effected by bending the
finger placed in the handle E', the operation can be carried out under continuous
observation in a careful and certain manner. When it is finished the tube B' is
pushed forward again (Figure 6) whereby the tool is placed close to the beak and
the instrument can then be withdrawn from the body without risk of injuring it by
the operating tool.
When another tool than scissors is used for the operation, it is similarly attached
to the sliding tube 131 in such a manner, that by the advance of said tube it is
placed close to the beak D, and can be removed from the same by drawing back
the tube B'.
The very essential advantage for surgery possessed by the instrument hereinbefore
described in comparison with the usual cystoscopes consists in the operator being
enabled by its use to perform the operation that may be required immediately at
the examination and with a full illumination of the part to be operated upon, and
can insert and withdraw the instrument simultaneously with the operating tools
without any risk of injuries being done thereby.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is:
Firstly. The arrangement of a cystoscope with tools or instruments for
performing surgical operations substantially as hereinbefore described and for
the purpose set forth.
Secondly. The combination with a cystoscope of an outer tube (B') sliding on
the tube (B) of said cystoscope and carrying a tool or instrument for performing
surgical operations worked by means of a rod (E) passing between said tubes, and
so arranged that by shifting the outer tube (B) the said tool or instrument can be
placed close to the beak (D) of the cystoscope while the same is inserted into or
withdrawn from the body and can be removed from said beak for performing the
operation, substantially as herein before described and illustrated and for the
purposes set forth.
