ことが可能となる。In the present invention, a tubular part for air suction is provided coaxially or in parallel with a measuring device or instrument that is slidably inserted into a hollow part provided in a conduit part of an endoscope, and a pressure-proof part such as a vacuum pump is provided. The probe of the measurement device is temporarily fixed by transmitting pressure protection to the tip of the tubular portion by the device and causing the tip of the tubular portion to stick to the mucous membrane at the measurement site. [Embodiments] Examples of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic diagram for explaining the temporary fixing device and temporary fixing method for an endoscope measuring device probe according to the present invention, taking as an example a case where a human stomach 30 is examined using a transoral endoscope. 12 is a measuring device used together with the endoscope. The embodiment shown in FIG. 1 has an air suction tubular section 14 and a measuring cable 16 slidably inserted into the tubular section 14. This measuring device 12 is inserted into a hollow portion 11 provided in the conduit portion IO of the endoscope, and its tip is connected to the tip 11A of the hollow portion at the tip 10A of the conduit portion 10.
It is possible to protrude from the wall and come into contact with a measurement location such as the stomach wall. FIG. 2 shows an enlarged view of the tip of the measuring device 12 shown in FIG. The tip of the measurement cable 16 is a probe 16A such as a measurement electrode, and the measurement cable 16 is housed within the tubular portion 14. Reference numeral 17 is a hollow portion within the tubular portion 14, through which pressure protection is applied as described later. FIG. 3 shows a measuring device 12' according to another embodiment, and while in FIG. 1 the measuring cape 16 and the tubular portion 14 are approximately coaxial, in this embodiment they are parallel. The two tubular parts 14 and 18 can be integrally molded or can be formed separately. After molding, it may be fixed with an adhesive or the like. FIG. 4 is a sectional view of the pressure-proof inlet portion 12B provided at the rear end side of the measuring device 12. This pressure-proof inlet section 12B is of the measuring device of the embodiment shown in FIG. 2, is connected to the tubular section 14, and has an L-shaped hollow section 20 inside. This hollow part 20 is connected to the hollow part 17 of the tubular part 14 on the one hand, and serves as a hollow part of the connecting part 19 on the other hand. This connection part 19 is connected to a vacuum pump 22 through a connection pipe 21.
Connected to automatic pressure protection devices such as As a vacuum pump, the one with the southern limit can be used, -15 cmHx. Any material that generates a certain degree of pressure resistance may be used. When using the measuring device of the embodiment shown in FIG. 3, the pressure-proof inlet section 12B as shown in FIG. In use, the endoscope conduit section 10 is first inserted into the stomach 30 through the subject's mouth, for example, as shown in FIG. 11
Insert the measuring device 12 or 12' from B. *Station device 1
2 or 12 degrees protrudes from the tip 10A of the conduit portion 10, and selects the location to be measured while looking through the finder 26 of the endoscope. After completing the selection, the tip of the measuring device, that is, the tip of the tubular portion 14, is selected. With the tip 14A sufficiently pressed against the mucous membrane, the switch SW of the vacuum pump 22 is turned on to supply electric power from the electric power source 24. The pressure generated by the vacuum pump 22 is transmitted to the tubular part 14 of the measuring device 12 via the connecting pipe 21 and the pressure inlet 12B, and therefore the pressure is transmitted through the hollow part 17 of the tubular part 14 to its tip 14A. communicated. As a result, the distal end 14A of the tubular portion 14 is adsorbed and fixed to the mucous membrane, that is, the stomach wall in FIG. 1. Since various inspections can be performed in this state, the measurement location will not shift during the inspection, and stable data can be obtained.
