- Endoscopic instruments are widely used in urology and are introduced through the urethra to perform various operative procedures at the operative field such as the bladder, prostate or urethra, typical instruments being the resectoscope, urethro-cystoscope, lithotriptor, and biopsy endoscopic forcep.
- a resectoscope is an endoscopic instrument for the transurethral resection of pathological tissues from the prostate or bladder without incision.
- a resectoscope of known and conventional construction is disclosed in FIGS. 1 and 2 as background for disclosure of the invention, and comprises the tubular sheath 2 which pro-. vides a passageway through the human urethra to the area of visual and operative interest, and which has a beak 4 at its distal end the shape of which is such that the side walls thereof recede in the proximate direction from the upper part of the distal end of the beak to the lower part.
- the sheath At its proximate end the sheath has a socket base 6 at which there is a tube 8 with stopcock 10 for the introduction of clear irrigating fluid, a thumb screw 12 for attaching the sheath s socket to the working element 14 for activating the cutting electrode in performing an operation.
- a tube 8 with stopcock 10 for the introduction of clear irrigating fluid
- a thumb screw 12 for attaching the sheath s socket to the working element 14 for activating the cutting electrode in performing an operation.
- the telescope 16 Within the sheath are the telescope 16, the cutting loop electrode assembly 18, and an outflow conduit 20.
- the telescope has an objective lens 22 at its distal end and an ocular lens (not shown) and eyepiece 24 at its proximal end.
- Light conductors extend through the telescope from an external connection 26 to the distal end for providing illumination.
- the cutting loop electrode assembly 18 comprises the elongated hollow stem 28 from the distal end of which there protrude the two parallel arms 30 which are connected at their distal ends by a depending semicircular bare wire cutting loop 32 which is activated by high frequency electrical energy to resect pathological tissues and coagulate bleeding vessels.
- the stem 28 and arms 30 transmit reciprocating movement of the working element 14 to the cutting loop.
- the working element 14 is connected by bridge member 32 to the cutting loop assembly stem 28 through the socket base 6 and may be moved toward and away from the socket base on runners 34 against the force of spring 36 by the surgeons operation of thumb holder 38, which movement is transmitted to the cutting loop through stem 28.
- an outflow conduit such as that shown at 20 in FIG. 1 has sometimes been provided within the sheath of known resectoscopes, and therefore within the inflow conduit which is provided by the sheath, having its distal or inlet end spaced a considerable distance proximate to the distal end of the sheath and the objective lens of the telescope, and
- An endoscopic urological instrument has continuous clear vision of the operative field caused by continuous inflow of clear irrigating fluid to the operative field and simultaneous continuous outflow of turbid fluid from the operative field. This is done by providing two separate conduits within the sheath of the instrument through one of which clear irrigating fluid is constantly supplied to the operative field and through the other of which turbid fluid is constantly removed from the field under the influence of suction.
- the outlet port of the inflow conduit is within the beak of the sheath and below and in front of the objective lens of the telescope which forms part of the instrument, and the inlet port of the outflow conduit opens from the exterior of the sheath above and to the rear of the objective lens and to the rear of the beak, so that clear fluid flowing through the inflow conduit is compelled to pass in front of the lens and into the operative field before reaching the entrance to the outflow conduit.
- the two conduits are of substantially the same size to permit substantially equal fluid flows and the continuous flow of clear and turbid fluids is maintained by suction applied to the outflow conduit.
- FIGS. 3 and 4 A resectoscope constructed in accordance with the invention is disclosed in FIGS. 3 and 4.
- the outflow conduit 40 is provided in the upper wall of the sheath 2, being formed by a part 42 of the upper wall of the sheath and a lower wall 44 which is spaced below the wall part 42.
- conduit 40 communicates with a source of suction through external tube 48 which is controlled by stopcock 50.
- tube 48 communicates with a disposal container 52 through flexible tube 54 and closure 56, and a pump 58 exhausts the container 52 thus applying suction to outflow conduit 40.
- the outflow conduit 40 is closed at its distal end as shown at 60 and the inlet to this conduit from the operative field is provided by one or more ports 62 in the upper wall of the sheath which are above and to the rear of the objective lens 22 of the telescope and to the rear of the beak 4.
- the second or inflow conduit 46 is formed by the interior of the sheath itself.
- the distal or outflow port of this conduit is open and within the beak 4 and below and in front of the objective lens of the telescope. At its proximate end this conduit communicates with an external tube 8 and stopcock 10 through which clear irrigating fluid is supplied to the operative field through the interior of the sheath.
- the two conduits are of such size that they conduct substantially equal flows of fluid, and it will be apparent that by manipulation of stopcocks 10 and 50 the inflow of clear fluid through conduit 46 and the outflow of turbid fluid through conduit 40 may be adjusted and controlled, thus also controlling the degree of distention of the bladder.
- the telescope tube I6 is lowered from its conventional position at the upper part of the sheath and made concentric with the sheath as shown in FIG. 4, thus enlarging the space available for conduit 40.
- one of the two conduits is provided by a tube which surrounds the telescope tube but is larger in cross section, and the second conduit is provided by the space within the sheath and outside the tube which provides the first conduit.
- the telescope 16 is surrounded throughout substantially its entire length by a second tube which engages the bottom and sides of the telescope and the space 72 between the upper part of the telescope and the upper part of tube 70 provides the outflow conduit, which is connected at the socket base 6 to a source of suction through external tube 48 and stopcock 50 as disclosed in FIG. 3.
- the outflow conduit 72 is closed at its distal end as shown at 74 and the inlet to this conduit is provided by registering ports 76, 78 in the upper wall of the sheath 2 and the upper wall of tube 70, which are to the rear of and above the objective lens of the telescope.
- the inflow conduit is provided by the space 80 within the sheath 2 and outside the tube 70 and this conduit communicates through external tube 8 and stopcock 10 with a source of clear irrigating fluid.
- the outlet port of this inflow conduit, at the distal end thereof, is within the beak of the sheath and below and in front of the objective lens of the telescope, and the two conduits are of such size that they conduct substantially equal flows of fluid.
- FIGS. 7, 8 and 9 A further embodiment of the invention is disclosed in FIGS. 7, 8 and 9.
- the telescope tube 16 is positioned at the upper part of the sheath 2 and is surrounded throughout substantially all of its length by a tube which is semi-circular in cross section with its arcuate wall 92 adjacent or abutting the inner wall of the upper part of the sheath and its flat lower wall 94 lying substantially in the center of the cross section of the sheath.
- Tube 90 is larger in cross section than the telescope tube and the free space 96 within it provides the outflow conduit according to the invention, while the inflow conduit 98 is provided by the space within the sheath and beneath tube 90.
- the outflow conduit 96 is closed by a wall 100 and the inlet to this conduit is provided by one or more pairs of registering openings 102, 104 in the upper wall of the sheath and the upper wall 92 of tube 90, respectively, which are to the rear of the beak of the sheath and above and to the rear of the objective lens of the telescope.
- the distal end of the inflow conduit 98 is within the beak of the sheath and below and in front of the objective lens of the telescope.
- the outflow conduit 96 is connected through external tube 48 and stopcock 50 to the source of suction as shown in FIG. 3, and at its proximate end the inflow conduit is connected through external tube 8 and stopcock to the source of inflowing clear fluid which is maintained more than 50 cm. above the level of the bladder.
- the two conduits are of such size that they conduct substantially equal flows of fluid.
- a fine metal tube 110 extends longitudinally within the sheath 2 and surrounds the telescope 16 and the stem and arms of the cutting loop assembly 18 and is larger than these parts in cross section, whereby the interior of the tube forms the inflow conduit 112 of the instrument.
- This tube is smaller in cross sectional area than the sheath, leaving a space 114 between the tube and the sheath which forms the outflow conduit.
- the tube 110 is cylindrical in shape at its distal end and proximal to this cylindrical part the sides of its lower part converge downwardly to provide a generally triangular shape as shown at 116 in FIG. 11 in order to increase the capacity of the outflow conduit 114.
- the inflow conduit provided by the interior of tube 110 communicates with external tube connection 8 through which clear irrigating fluid is provided to the operative field.
- the outflow conduit 114 is closed by a ring 118 which extends radially from the circular exterior wall of the tube 110 to the interior wall of the sheath 2, thus closing the distal end of the outflow conduit 114, the inlet to which is provided by two or more openings 120 in the sheath 2 adjacent the distal end thereof, which are to the rear of the objective lens of the telescope.
- the outflow conduit] 14 communicates with a source of suction through external tube 48, and turbid fluid from the operative field is discharged through this external tube connection to the disposal container, the discharge being accelerated by suction to compensate the difference of pressure between the inflow pressure cm. of water) and the intravesical pressure below 30 cm., avoiding the accumulation of turbid fluid in the bladder.
- the inflow conduit 112 is open and within the beak and is below and in front of the objective lens of the telescope.
- the closure at the distal end of the outflow conduit is provided by causing the interior wall of the sheath to converge slightly from its proximate end to the distal end, the difference in diameters at the two ends being of the order of 1 mm.
- the exterior diameter of the closure ring 118 is made equal to the interior diameter of the sheath at its distal end so that when the tube and its closure ring 118 are inserted into the sheath from the proximate end thereof the insertion will be stopped by engagement of the periphery of the closure ring 118 with the smaller end of the sheath at the distal end thereof, thereby providing the required closure of the outflow conduit.
- the parts are so constructed that this engagement of the closure ring with the interior of the sheath will take place at a point in front of, Le, on the distal side of, the ports which provide the inlet to the outflow conduit.
- the tube 110 surrounds the stem 20 and the arms 30 of the cutting loop assembly 18 as well as the telescope 16.
- the arms 30 of the cutting loop assembly are elongated by approximately 2 centimeters with respect to the length of the arms of the conventional cutting loop assembly and because of this elongation the bare cutting wire 32 of the cutting loop assembly is positioned outside the distal end of tube 110 in the normal, un-extended position of the cutting loop assembly, and as the cutting loop assembly is operated the arms 30 are stabilized by sliding engagement with the inner walls of tube 110 as illustrated in FIG. 11.
- a short tube is mounted on the distal end of stem 20 and surrounds the distal end of the telescope tube 16 and slides along that tube when the cutting loop assembly is reciprocated in performing an operation.
- the parts are so designed and constructed that the inflow and outflow conduits are of substantially the same size so that they will conduct substantially the same volume of fluid per unit of time, thus permitting the continuous inflowoutflow fluid system which is provided for the first time by this invention, and the outflow conduit is subjected to suction in the manner and with the results described above.
- the arrangement of the parts of the instrument is such that the outlet port of the inflow conduit and the inlet port of the outflow conduit are separated in space, with the objective lens of the telescope and the operative field itself in the path of flow of fluid from the inflow conduit to the outflow conduit so that clear inflowing fluid is constantly in front of the objective lens, giving continuous clear vision.
- cystoscopes other than resectoscopes will be apparent to urological surgeons and others skilled in the arts to which the invention relates, and will usually involve the choice of which of the two conduits is to be used for inflow or outflow.
- a urological endoscopic instrument comprising an elongated cylindrical beaked sheath, a telescope extending longitudinally and interiorly of the sheath and having an objective lens at its distal end, an inflow conduit extending longitudinally and interiorly of the sheath having its discharge port below and in front of the objective lens and within the beak of the sheath, an external fluid conducting connection at the proximate end of the inflow conduit for connection to a source of clear irrigating fluid, an outflow conduit extending longitudinally and interiorly of the sheath and having an inlet port provided by at least one opening from the outside of the sheath above and to the rear of the objective lens and to the rear of the beak, and means for applying suction to the outflow conduit.
- inflow conduit is formed by the interior of the sheath and the outflow conduit is formed by the space between the upper wall of the sheath and a second wall spaced radially inwardly of the sheath therefrom.
- An instrument according to claim 1 comprising a tube extending longitudinally and interiorly of the sheath and surrounding the telescope and being larger than the telescope and smaller than the sheath in cross section, the outflow conduit being provided by the inte rior space of the tube and the inflow conduit being provided by the space between the tube and the sheath.
- An instrument according to claim 6, comprising in addition a closure between the distal end of the tube and the interior wall of the sheath, and at least one opening in the sheath proximate to the closure forming an inlet for the outflow conduit.
