摘要： An endoscope system is provided in which air is pumped into a first channel into the endoscope in order to pressurize the body cavity and a forceps channel is connected to a suction pump in order to drain the body cavity of fluid, air and debris. Either a second suction pump or a second supply of air is connected to the forceps channel along with a pressure detector for controlling suction. Further, a suction tube is also provided which is connected to, and which communicates with, a forceps channel in which a medical tool is adapted to be inserted, and a suction device is, in turn, connected to and communicates with the suction tube. Pressure within the suction tube is detected by a pressure detecting device, and the detected pressure is indicated on the display. A suction control device is provided which controls operation of the suction device by operating based upon an output signal from a pressure setting device for setting a maximum value for the body cavity pressure and an output signal from the pressure detecting device. A laser knife is also provided which includes a protective pipe surrounding a fiber optic laser transmitting member for forming a first gap and a tube surrounding the protective pipe to form a second gap. Gas is passed through the first gap to cleanse the emitting end of the laser transmission member. A pressure detecting device is coupled to the second gap in order to monitor pressure within the stomach, and a suction device which is responsive to the pressure detecting device is also connected to the second gap in order to control gas pressure within the stomach.

摘要： A closed, hollow connector housing mounts a pair of laser fibers in end facing position internally within the hollow connector housing for immersion in a light-transmissible liquid. A pump drives the light-transmissible liquid within a circulation loop through pipes opening to opposite sides of the connector housing such that the liquid flows across the interface between the end to end facing optical fibers. Heat generated by scattered light reflections is dissipated by circulation of the liquid and the occurrence of scattered reflections is minimized by the presence of the liquid. A flow rate sensor responsive to the rate of flow of the light-transmissible liquid feeds an electrical signal through a drive circuit to a shutter mechanism for preventing light-transmission from the power laser light source to one of the laser fibers absent a sufficient of circulation flow rate of the light-transmissible liquid through the connector housing.

摘要： An apertured reflection plate obliquely oriented with respect to a fiber optical axis allows light to be introduced through the aperture to a condenser lens for introduction to the fiber. Light reflected from the exit face of the fiber will come out of the entrance end face, be spread by the lens and be reflected by the outer regions of the reflection plate to a light detecting element. In response to an abnormal detection signal, the laser can be disabled.

摘要： A length-measuring device comprises a flexible tube having a first slit and a second slit disposed rearwardly of the first slit, said tube being bendable at each of the first and second slit, and said tube further having a length-measuring portion extending forwardly from the first slit to a distal end of said tube; and means for bending said tube at the first and second slits. Typically, the bending means is a wire which has a connection relation with the length-measuring portion to pull the same. The length-measuring portion is coated with regularly arranged scale marks. After being projected from a forceps channel of an endoscope, the length-measuring portion is pulled to assume a T-shape. The length-measuring portion can be disposed at the center of a field of vision of the endoscope, and also can be easily brought into intimate contact with a target affected part. In a reference color display device, the length-measuring portion is replaced by a distal end portion coated with three primary colors.

摘要： An endoscopic length-measuring tool for measuring the size of a diseased part within patient's body cavity. A plurality of splits are formed in a front end portion of a flexible tube of the tool so as to extend in parallel to an axial direction of the tube and to have equal lengths. Each of the plurality of strips is defined between adjacent splits. Radially outwardly bendable portions and radially inwardly bendable portions are formed on each strip. An operating wire is axially and movably disposed within the tube. The front end of the operating wire is retained on a portion of the tube located forwardly from the splits. When the operating wire is moved axially and rearwardly relative to the tube, the strips are bent at the bendable portions and spread radially outwardly, so that a length-measuring section on the strip is disposed within an observation visual field of an endoscope.

摘要： A laser knife which supplies water to a rod member applying laser radiation to tissue or the like by means of using the air supply passing air between a fiber optic laser transmitting member and a hollow tube. Air issuing from the tube may be bled to the atmosphere through a bleed valve. Closure of the bleed valve pressurizes an annular space in flow communication with the upper portion of a fluid supply tank. Pressurization of the tank forces fluid from the tank into an annular space within the device through orifices in flow communication with grooves adjacent the rod member. In such a manner, the pressurization of the air supply system causes fluid to flow over the rod member to prevent adherence of tissue and the like to the end of the rod transmitting the laser radiation.
