Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forceps device for a calculus that is used by being inserted into an endoscope, for example, and crushes a large calculus such as a gallstone to reduce the size of the calculus. The present invention relates to a forceps device for calculi that can be collected in a size.

〔発明の背景〕[Background of the Invention]

When treating and recovering a stone in a body cavity, for example, a gallstone using an endoscope, if the stone is large, it may be difficult to recover the stone as it is. In such a case, it is necessary to crush the stones to an appropriate size so that they can be collected. Conventionally, a basket-type forceps is made to project from the inside of the insertion part to the outside of the tip of the insertion part through the forceps port of the insertion part of the endoscope to enable capturing of calculi and pulling toward the forceps passage side. It is known that a calculus that is caught is crushed by a protrusion or a needle by pulling it toward the forceps mouth side.

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, in such a conventional device, it is not always possible to obtain a sufficient crushing force because the calculi are crushed by the protrusions and needles,
Moreover, the crushing action is uncertain, and the operation is troublesome.

In order to achieve the above object, the present invention is provided with a basket-type forceps for collecting calculi, which is composed of a plurality of basket wires, at the tip of a flexible tube so as to project and retract, and at the tip of the flexible tube, a pair of grasping claws are provided. An open / close type forceps for crushing calculi was provided, and the operation wires of the forceps inserted so as not to interfere with each other in the insertion part were connected to the operation knobs of the operation part, and the calculus captured by the basket type forceps was connected to the open / close type forceps. It is designed to be crushed by holding it with a grasping claw.

As shown in FIGS. 2 to 8, the basket type forceps 8 has four
The basket wire 8a of the book is connected at its tip with a tapered stopper 8b shown in FIG. 1, and has a small diameter forceps port 2 as a position regulating means opened around the axis of the tip metal fitting 6 at equal intervals.
It projects from 0 so that it can be sunk. The position of the basket wire 8a is regulated by the forceps port 20 of the position regulating means so as not to interfere with the open / close type forceps 10 when the open / close type forceps 10 is opened / closed. Each basket wire 8a is made of an elastic material and bends outward by self-elasticity when it protrudes, and spreads like a net. Each basket wire 8a is connected to the flexible tube 4
It is inserted inside and is connected to the operation knob 14 via the operation wire 13 as described later.

Further, the open / close type forceps 10 is composed of a pair of grasping claws 10a whose tips have an acute angle. Each of the claws 10a is pivotally supported at the base end side by a support shaft 22 fixed to the tip end fitting 6, and can be opened and closed so that the tip end side engages with each other, and is arranged between each pair of basket wires 8a, 8a. Each of the claws 10a is connected to the operation wire 26 through the link 24 and the connecting tool 25 in the tip fitting 6 and is opened and closed by pushing and pulling the operation wire 26. The operation wire 26 is connected to the operation knob 16, and the operation wire 2
When the tip 6 is pushed forward of the tip fitting 6 (in the direction of arrow a in FIG. 3), the claws 10a open, and in the rear (direction of arrow b in the figure).
When the nails are pulled to each other, the claws 10a bite each other (close)
It is like this.

That is, in the case where a plurality of basket wires 8a are connected to the operation knob 14, the basket wires 8a are bundled into one in the middle of the flexible tube so that the flexible operation wire 13 can be obtained in consideration of the assemblability and the smoothness of operation. Connect the operation wire 1
It is considered most desirable to connect 3 to the operation knob 14. However, in this case, each basket wire 8a
Since the converging portion of the and the operation wire 26 of the open / close type forceps 10 approach each other, they are likely to interfere with each other.

Therefore, the hollow shafts 28a, 28b are slidably inserted into the flexible tube 4 at a predetermined interval and slidably.
The operation wire 26 of the open / close type forceps 10 is slidably inserted into 8b. On the other hand, each basket wire 8a is fixed to the outer peripheral portion of the hollow shaft 28a on the tip fitting 6 side via an adhesive portion 30 such as brazing as shown in FIG. As shown in FIG. 11, the shaft 28b is converged on one side of the outer peripheral portion and fixed to the shaft 28b via an adhesive portion 32 such as brazing. The basket wire 8a
The end portion of the portion further extending toward the operation portion 12 side is the 12th
As shown in the figure, it is inserted into one end of a hollow shaft-like connector 34 arranged in parallel with the operation wire 26 of the open / close type forceps 10,
This connecting tool 3 is fixed by an adhesive portion 36 such as brazing.
Similarly, it is connected to one flexible operating wire 13 inserted and attached to the other end of 4 via an adhesive portion 36.

Then, the operation wires 13 and 26 extend toward the operation portion 12 side and the brackets 40 and 42 are attached to the operation knobs 14 and 16, respectively.
Are connected via. The operating portion 12 is configured by attaching the grip ring 18 to the rear end of the operating rod 46 connected to the flexible tube 4 via the connecting tube 44. Further, the operation knob 14 of the basket type forceps 8 and the operation knob 1 of the opening / closing type forceps 10
6 is a tubular body with a collar, and is slidably fitted on the outer peripheral portion of the operating rod 46. Operation knob 1 for basket type forceps 8
4 is slidable in both axial directions, and basket type forceps 8
Is stopped by the stopper 48 at the maximum movement in the retracting direction (rightward in FIG. 9). Operation knob 16 of the open / close type forceps 10
Is urged by a compression coil spring 50 provided behind the stopper 48 (on the right side in the figure) in the moving direction (on the right side in the figure) in which the open / close type forceps 10 is closed. In addition, each operation knob 1
The screws 4 and 16 can be fixed at arbitrary sliding positions by screws 52 and 54.

Next, the operation will be described with reference to FIGS. 13 (A) to 13 (E). First, the flexible tube 4 is inserted to the calculus A position in the body cavity (FIG. 13 (A)). In this case, the basket type forceps 8 is in the maximum retracted state, and the open / close type forceps 10 is in the closed state. The insertion action is performed by inserting the insertion portion of an endoscope (not shown). After inserting to a predetermined position, the knob 14 is advanced to the flexible tube 4 side, and the basket type forceps 8
To be in an expanded state. As a result, the body cavity is expanded and the calculus A can be captured by each basket wire 8a (FIG. 2B).

Next, the knob 16 is advanced to the flexible tube 4 side, each claw 10a of the open / close type forceps 10 is opened, and the knob 14 is further operated.
Retreat to the 2 end side, retract the basket wire 8a,
The captured calculus A is pulled toward the open / close type forceps 10 side ((c) of the same figure).

When the calculus A is drawn up between the claws 10a of the open / close type forceps 10, the claw 10a is closed by retracting the knob 16, and the calculus A is bitten. Along this biting direction,
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 biting the nail 10a is crushed ((D) in the figure,
(E)). If this operation is performed a required number of times, the calculus A can be crushed to a size capable of being collected or discharged.
