するものが知られている。When treating and recovering a stone in a body cavity, such as a gallstone, using an endoscope, if the stone is large, it may be difficult to recover it as it is. In such cases, it is necessary to crush the stone to an appropriate size that can be recovered. Conventionally, basket-shaped forceps were protruded from the inside of the insertion tube to the outside of the tip of the insertion tube through the forceps port of the insertion tube of the endoscope, making it possible to capture stones and pull them toward the forceps passage. It is known that the captured stone is pulled toward the mouth of the forceps and crushed using protrusions or needles.
しかし、このような従来の装置では突起や針によっては
結石を破砕するため必ずしも十分な破砕力が得られず、
また破砕作用も不確実で、操作も面倒であるなど、満足
な結果を得られないことが多い。However, with these conventional devices, the protrusions and needles may not necessarily provide sufficient crushing force to crush the stone.
Furthermore, the crushing action is uncertain and the operation is troublesome, so that satisfactory results are often not obtained.

2. Note that the operating section 12 is connected to the connecting tube 44.
It is constructed by attaching a grip ring 18 to the rear end of an operating rod 46 that is connected to the flexible tube 4 via a. Further, the operating knob 14 of the basket-type forceps 8 and the operating knob 16 of the opening/closing forceps 10 are formed into a cylindrical shape with a flange, and are slidably fitted onto the outer circumference of the operating rod 46. The operating knob 14 of the basket-type forceps 8 is slidable in any axial direction, and is stopped by a stopper 48 when the basket-type forceps 8 is moved at its maximum in the retraction direction (to the right in FIG. 9). Operation knob 1 of open/close forceps 10
6 is biased by a compression coil spring 50 provided behind the stopper 48 (to the right in the figure) in the moving direction in which the opening/closing forceps 10 is closed (to the right in the figure). In addition, each operation knob 1
4.16 can be fixed at any sliding position using screws 52.54.

同図（Ｂ））。Next, the operation will be explained with reference to FIGS. 13(A) to 13(E). First, insert the flexible tube 4 to the stone A position in the body cavity (
Figure 13(A)). In this case, the basket-type forceps 8 is kept in a retracted state to the maximum extent, and the open/close-type forceps 10 is kept in a closed state. The insertion action is performed by, for example, inserting it through an insertion section of an endoscope (not shown). After inserting to a predetermined position, the knob 14 is moved forward toward the flexible tube 4 side, and the basket-shaped forceps 8 are protruded to be in an expanded state. As a result, the body cavity is expanded and the stone A can be captured by each basket wire 8a (
Same figure (B)).

Since the knob 16 is biased by the compression coil spring 50, the biting action can be easily performed. As a result, the stone A that has been bitten by the nail 10a is crushed ((D) in the same figure).
(E)). By repeating this operation a required number of times, stone A can be crushed to a size that can be recovered or discharged.
