Definitions

  • the present invention relates to medical operating devices and in particular to a device such as an endoscope employing means for simultaneously bathing a body cavity.
  • Devices such as endoscopes are well known for performing many types of operations, particularly in transurethal, urinary and bladder sections.
  • the removal of a bladder tumor or growth in the bladder or bladder-neck is accomplished by employing high frequency current during which it is preferable to first expose the bladder or at least the situs of the operation to view and then to perform the electrical cutting while simultaneously bathing the area with a fluid media, as for example water.
  • a fluid media as for example water.
  • a water stream having a measurable pressure must be provided. Accordingly, the endoscope used for the operation has been provided with conduit means for delivering the v fluid to the situs of the operation.
  • the present invention has as its object the provision of apparatus and particularly an improved endoscope means which overcomes the disadvantages of the prior art and provides means for performing the operation of the type described without interruption and with the security desired.
  • the object of the present invention is obtained by providing an endoscope device in which bathing media is continuously with or intermediate the operative steps in short succeeding intervals simultaneously pumped into and out of the body cavity, the inveed and the discharge being maintained in equal volume. In this manner it is assured that during the operation the delivered bathing media is always equal to the discharged bathing media volume. This prevents the excess filling of the bladder in every instance. It is, therefore, possible for the first time to continue the operation from beginning to end without interruption.
  • the bladder may thus be filled with a standing water column, before the operation is commenced and then the tissue cut can be made with the bladder full of bathing liquid as is most desirable from a medical point of view.
  • an exchange of equal volume of liquid may be effected, so that while the bladder constantly remains full, the liquid together with tissue, blood, etc., is withdrawn, cleansed and recirculated and fresh liquid added. At no time does excess liquid accumulate in the bladder.
  • the pumping of the bathing media into and out of the body is accomplished through the use of a tubular pump having a feed and discharge tube arranged in parallel and a rotary actuator eccentrically arranged between them.
  • This structure has the particular advantage that the eccentric actuator can be arranged and connected simultaneously to pressurize the feed tube and to exhaust the discharge leading to the corresponding members in the endoscope device, so that it can control simultaneously both the feeding and discharge of liquid through the device.
  • This arrangement has further advantages in that it is of great simplicity, it is exteremely efiicient and insures that both the pumping in and exhausting out of the bathing fluid is created from a single source having the same stroke frequency and volume of pumping.
  • the endoscope shaft may be formed having first a nozzle portion at the distal end of the shaft by which the bathing media is delivered directly to the site of the operation, and a second separate discharge channel from the site.
  • the connection for the actual intake and for the discharge of the media may then be arranged on the headportion or proximal end of the endoscope shaft.
  • This arrangement has the advantage that separate channels or ducts can be provided through the endoscope for the intake and for the outlet of fluid. Further, the discharge channel can be made at least equal to or greater in cross-section than the inlet channel.
  • the cross-section of the inlet channel is maintained substantially smaller than the discharge channel so that a high enough pressure is developed to wash the tissue from the lens etc., but accumulation of the'liquid in the cavity is avoided.
  • the separation of the discharge channel from the inlet channel it is insures that at least the same volume of fluid is pumped out of the body cavity as is pumped into it.
  • a further feature of the present invention resides in the provision that the inlet channel is formed in the nature of a throat or bulge arranged about the viewing tube of the endoscope whereby the throat provides an annular channal closed with respect to the viewing tube and separate therefrom. Further this construction permits the viewing tube to be independently and removably inserted in the shaft so that it can be withdrawn easily and simply for cleaning and sterilization. In addition, the interior of the shaft is also available by being removable of the viewing tube for cleaning and sterilization. The prior techniques of soldering the inlet channel on the viewing tube, and thus requiring a small cross-section is avoided.
  • FIG. 1 is a plan view of apparatus embodying the present invention which is connected to an endoscope device, seen extending perpendicularly to the plan of the drawing;
  • FIG. 2 is a partially sectional elevational view of the endoscope adapted to receive the apparatus of the present invention.
  • the device comprises an endoscope shaft 14 carrying at its proximal end a sleeve-like or throat connection 14a for a first inlet 12 having adjustable pet-cock valve and a second inlet 13 through which fluid media may be delivered.
  • a sleeve-like or throat connection 14a for a first inlet 12 having adjustable pet-cock valve and a second inlet 13 through which fluid media may be delivered.
  • resilient flexible infeed tubes 7 and 9 which are jointly connected to a Y-connection l 1 which is in turn connected to means for storing the liquid media such as a bottle 10.
  • Located above the connection 14a is an outlet 25 to which is connected to the end of a resiliently flexible discharge tube 8. The outlet 25 is not seen in FIG.
  • the inlet 13 is in communication with a channel 1 passing formed by a tube passing through a groove in endoscope shaft 14, extending in the longitudinal direction with the guide tube 3.
  • the endoscope comprises an optical eyepiece 24 mounted at the upper end of a viewing tube 4', which extends through a surrounding guide tube 3.
  • an objective lens 15 through which the situs of the operation can be viewed by the doctor.
  • the viewing tube is set within the endoscope shaft 14 and thus forms the annular discharge channel 2.
  • the channel 1 is formed by a tube or tubular section formed along the length of the guide tube 3 and the viewing tube 4.
  • a portion of the viewing tube 4 and the exterior endoscope shaft 14 extends beyond the point at which the lens 15 is secured, thus extending the discharge channel 2 below the lens.
  • a portion of the shaft 14 terminates above the lens 15 so that the channel 2 opens at a level higher than the lens 15. It will also be observed that the discharge channel 2 has a greater cross-sectional area than the inlet or feed channel 1.
  • An elongated wire having a loop 16 at its lower end extends between the endoscope shaft 14 and the viewing tube 4 below the lens 15.
  • the wire 16 is secured to a movable sleeve 17 located about the guide tube 3 which is connected via a finger grip 21 and an articulated pair of levers l8 and 22 to a boss at the upper end of the endoscope on which the eye piece is secured.
  • the boss contains a palm or hand grip 23 permitting the carrier sleeve 17 to be movable axially along the tube viewing tube 4 by manipulation of the finger grip 21.
  • the wire loop 16 may be extended or retracted with respect to the situs of the operation.
  • the wire loop 16 of the course comprises the electrode of the high frequency apparatus and is connected to a suitable power source in known manner.
  • connection 14 a for the inlets l2 and 13 sits above the shaft 14 and has a small conduit which connects the inlet 12 to the annular channel 2.
  • the inlet 12 is provided with the pet-cock so that it can be opened and bathing fluid delivered directly through this discharge channel 2 into the body cavity so that the bladder may be initially filled with a predetermined amount of liquid via the larger discharge channel so that the conductive electrode will have sufficient conducting media and the cavity will be sufficiently bathed, before the moment at which the operation may begin.
  • the inlet tube 7 from inlet 13 and the outlet tube 8 from discharge 25 pass through a pump 5 having a rotatable eccentric actuator 6.
  • the pump 5 comprises a body in which a rotary motor having a shaft on which the actuator 6 is mounted.
  • the actuator 6 compresses the tubes in rhythmic sequence so as to pump fluid through tube 7 and exhaust fluid through tube 8.
  • the tubes 7 and 8 and the excenter 6 are positioned relative to each other that the stroke, and the fequency of the pumping action is the same on both tubes, although in opposite phase or direction and the volume of compressed fluid in each of the tubes is the same.
  • the pet-cock connection 12 is opened so that the cavity is initially filled to the most optimal level for the operation. Thereafter, it is closed so that liquid is delivered only through the smaller inlet 13 and channel 1 by the operation of the pump 5. Simultaneously the same volume of fluid is withdrawn from the site of the operation through the discharge channel 2.
  • the inlet connection 13 passes through a cut in the wall of the endoscope shaft 14 and is soldered or welded to the tubular channel 1 to provide a fluid tight arrangement so that the infeed of liquid is sealed from the connection 12.
  • the feed channel 1 extends the length of viewing tube 4 and opens in the neighborhood of the objective lens 15 so that the liquid pumped through the nozzle-like opening tends to pass over this objective lens 15 maintaining it free of any blood or particles during the operation.
  • the discharge flow of the liquid passes through the opening in the annular discharge channel 2 one portion of which is immediately adjacent the electrode wire loop 16 and the other portion of which is located above the objective lens 15. In this way a current of fluid from the inlet to the outlet is created insuring absolute cleaning of both the situs of the operation and the distal end of the endoscope.
  • the eye piece 24 and the viewing tube 4 are jointed together to be removable axially from the endoscope shaft 14 by being pulled upwardly through the sleeve 17 and the boss holding the lever 22.
  • the bladder can be easily and quickly emptied, since the liquid in the bladder will all run quickly through the hollow interior of the endoscope shaft 14 without interruption. This is advantageous particularly should an emergency occur during the operation which requires instantaneous emptying of the bladder.
  • removal of the device permits the eye piece to be cleaned and sterilized and opens the entire enterior of the endoscope to cleaning and sterilization also.
  • the present device is employed by first inserting the endoscope shaft 14 together with the viewing tube 4 in the body cavity with the pet-cock opened so that the body cavity is filled with the bathing liquid delivered from the reservoir 10 through the annular discharge chamber 2.
  • the pump 5 is arranged so that the discharge tube 8 is closed so that the liquid does not prematurely flow out of the body.
  • a pet-cock or other clamping valve mechanism may be used on the tube 8 rather than using the pump to close the tube 8. Such mechanism may be located either directly on the tube or on the discharge connection 25.
  • the pump 5 is then activated upon the beginning of the operation itself and an additional amount of fluid is directed via the Y-joint 11 into the tube 7, to the site of the operation through the inlet channel 1. Since the inlet channel 1 is of a smaller cross-sectional area than the discharge channel 2 the amount of fluid passed into the bladder in this direction is so great as to cause excess filling of the bladder.
  • the pet-cock 12 is closed and if a clamp is used the clamp or other device in discharge connection 25 and discharge tube 8 is opened. Thereafter the doctor may begin his work and perform the operation by activating the electrode 16.
  • the pump 5 is continuously operated so as to continuously feed and withdraw a constant amount of fluid-from the body cavity during the course of the operation.
  • the doctor may operate the pump at intervals and only when the doctor considers it necessary to remove blood and tissue from the site of the operation. In either event, the same volume of water is delivered to the body cavity as is simultaneously removed therefrom setting up a circulation of fluid about the objective lens 5, the electrode 16, as well as in the site of the operation so that the site is maintained in clean and suitable condition for the continuation of the operation.
  • the discharge channel 2 is larger in crosssection than the inlet channel 1 it is clear that the body cavity will at no time be filled with an excess of fluid and further the blood particles, tissue particles, and other solid material withdrawn will easily pass through the discharge channel.
  • the bladder is constantly maintained with an optimal amount of fluid providing the necessary conductive media for the electrode as well as suitable bathing and therapeutic media.
  • the smaller inlet cavity has a further advantage in that, while the same volume of fluid is directed into the body as is removed therefrom, the smaller cross-section increases the pressure of the fluid so that the complete and proper washing of the area is obtained.
  • the mouth of the inlet channel 1 is positioned between the mouth of the outlet channel 2 so that the two are not in close proximity to each other and thus the incoming water can not be diverted to the outlet without further performing its cleaning function.
