Embodiment 1

[0035] [the whole frame]

[0036] The basket-type endoscope treatment appliance of this embodiment, such as figure 1 As shown, it has: a slender flexible sheath 2 made of resin or coils, and an operating part 10 is installed at the rear end; an operating steel wire 3 can be inserted through the flexible sheath freely. Inside the cover 2; a cylindrical front-end metal fitting 20 made of hard metal material, which is arranged at the front end of the flexible sheath 2; and a net basket part 40 for crushing foreign matter, which is connected to the The front end of the operation wire 3 is used as a treatment part that can protrude or retract from the flexible sheath 2 by pushing the operation wire 3 toward the front end or pulling it toward the rear end through the operation of the operation part 10 .

[0037] Furthermore, in this embodiment, the figure 1 The direction on the right side of the operation part 10 is referred to as the rear end side, and will be directed toward fi...

Embodiment 2

[0075] Second, use Figure 6 A second embodiment of the basket-type endoscope treatment tool 1 of the present invention will be described.

[0076] Figure 6 Among (a) is the external view showing the front joint 6, Figure 6 (b) in (b) is from the front side ( Figure 6 (a) above) observe Figure 6 In the diagram of (a), Figure 6 (c) in the Figure 6 The sectional view taken along line D-D in (b), Figure 6 (d) in the Figure 6 In the cross-sectional view of the E-E line in (b), the basket steel wires 41, 42 show a state of being closed and not expanding in a cage shape.

[0077] In addition, since it is the same as that of the first embodiment except for the configuration of the tip joint, description thereof will be omitted.

[0078] In the aforementioned embodiments, the example in which the ribs 6b of the folded portions 41a, 42a of the basket steel wires 41, 42 are fixed in the groove 6d of the front joint 6 is shown, but it is not limited thereto. The basket ty...

Embodiment 3

[0084] Second, use Figure 7 A third embodiment of the basket-type endoscope treatment tool 1 of the present invention will be described.

[0085] Figure 7 (a) is an external view showing the front joint 50, Figure 7 (b) in (b) is from the front side ( Figure 7 (a) above) observe Figure 7 In the diagram of (a), Figure 7 (c) in the Figure 7 In the cross-sectional view of the F-F line in (b), the basket steel wires 41 and 42 show a state of being closed and not expanding in a cage shape.

[0086] In addition, since it is the same as that of the first embodiment except for the configuration of the tip joint, description thereof will be omitted.

[0087] In the above-mentioned embodiment, the example in which the distal end joint is formed by assembling two members of the joint main body and the joint outer cylinder is shown, but it is not limited thereto. In the basket-type endoscope treatment instrument of the third embodiment, the front end The joint 50 is formed i...

Abstract

[Problem] To provide a basket-type treatment instrument for an endoscope such that wires constituting a basket are not liable to be damaged. [Solution] A basket-type treatment instrument 1 for an endoscope having a basket part 40 formed such that a plurality of basket wires 41, 42 elastically expand or contract radially, wherein folded-back parts 41a, 42a formed by folding back substantially center portions of the basket wires 41, 42 are hooked to a substantially cylindrical first rib 6b fixed in a perpendicular direction to the cylinder axis of a distal tip 6, whereby the distal tip 6 retains the distal sides of the basket wires 41, 42 together.

Description

technical field [0001] The present invention relates to a basket-type endoscope treatment instrument, which includes a treatment part, the treatment part is inserted into a body cavity, and foreign objects such as stones in the body cavity are clamped and crushed by a basket composed of a plurality of elastic steel wires, In particular, the present invention relates to a basket-type endoscope treatment instrument in which steel wires constituting the basket are not easily damaged. Background technique [0002] In order to recover and crush foreign bodies such as stones in the body cavity, doctors usually use a basket-type endoscope disposal device, which can protrude or retract from the elongated flexible sheath and can be stretched in a cage shape Free basket department. The basket-type endoscope treatment instrument is inserted into the endoscope channel with the basket part stored in the flexible sheath, and gradually approaches foreign objects such as stones in the body...
