no. 1 Embodiment approach

[0022] refer to Figure 1 to Figure 5 The first embodiment of the present invention will be described. figure 1 It is a figure which shows the treatment instrument (grip treatment instrument) 1 of this embodiment. Such as figure 1 The treatment instrument 1 has a length axis C as shown. Here, the side along the direction of the longitudinal axis C is referred to as the distal side (arrow C1 side), and the side opposite to the distal side is referred to as the proximal side (arrow C2 side).

[0023] The treatment instrument 1 includes a retainable housing 2 , a shaft (sheath) 3 coupled to the housing 2 from the distal end, and an end effector 5 attached to the distal end of the shaft 3 . The shaft 3 extends along the longitudinal axis C from the proximal end side to the distal end side, and the central axis of the shaft 3 is substantially coaxial with the longitudinal axis C. In the shaft 3 , the side facing the casing 2 is called the proximal side, and the side facing the ...

no. 2 Embodiment approach

[0057] Next, refer to Figure 7A ~ Figure 8 A second embodiment of the present invention will be described. The second embodiment is obtained by modifying the structure of the first embodiment as follows. In addition, the same code|symbol is attached|subjected to the same part as 1st Embodiment, and description is abbreviate|omitted.

[0058] Figure 7A and Figure 7B is a diagram showing the internal structure of axis 3, Figure 8 It is a figure which shows the structure of the connection part of the shaft 3 and the housing 2. Such as Figure 7A and Figure 7B As shown, in this embodiment as well, the interlocking member 51A is fixed to the operation wire (bending drive member) 45A, and the interlocking member 51B is fixed to the operation wire (bending drive member) 45B. Therefore, also in this embodiment, the interlocking members 51A, 51B are linked with the corresponding operation wire (the corresponding one of 45A, 45B) respectively in conjunction with the bending ...

no. 3 Embodiment approach

[0072] Next, refer to Figure 10 and Figure 11 A third embodiment of the present invention will be described. The third embodiment is obtained by modifying the structure of the first embodiment as follows. In addition, the same code|symbol is attached|subjected to the same part as 1st Embodiment, and description is abbreviate|omitted.

[0073] Figure 10 and Figure 11 It is a figure which shows the structure of the inside of the case main body 11 of the case 2, and the inside of the rotating member (rotation knob) 25. Figure 10 is a stereogram, Figure 11 It shows a cross section substantially parallel to a predetermined rotation axis R (longitudinal axis C) and substantially parallel to the width direction of the casing 2 (directions indicated by arrows W1 and W2 ). Such as Figure 10 and Figure 11 As shown, in this embodiment, the interlocking member 71 interlocked with the bending operation of the end effector 5 with respect to the shaft 3 is provided on the ben...

Abstract

When the shaft (3) is rotatable with respect to the housing (2) around a predetermined axis of rotation, and the end effector (5) is mounted on the shaft (3) in such a manner that it can be bent or bent relative to the shaft (3), In an instrument (1), when an end effector (5) is bent or bent, its rotation about a predetermined rotation axis is suppressed. The interlocking member (51A, 51B) is independently provided with respect to the shaft (3) in a state where the rotation relative to the housing (2) is restricted or the rotation relative to the shaft (3) is restricted A receiving portion (52) is provided in a rotated state. The interlocking member (51A, 51B) is engaged with the receiving part (52) by interlocking the bending action or the bending action of the end effector (5). , thereby inhibiting the rotation of the shaft (3) about the prescribed axis of rotation.

Description

technical field [0001] The invention relates to a treatment instrument for treating a treatment object by using an end effector. Background technique [0002] U.S. Patent No. 5,383,888 discloses a treatment instrument in which an end effector for treating a treatment object is provided at the tip of a shaft. In this treatment tool, a shaft is connected to a holdable housing, and the handle is opened or closed with respect to the handle of the housing to close between a pair of grip pieces in the end effector. By closing the grip sheets, a treatment object such as living tissue is gripped between the grip sheets. In addition, a rotating member (rotary knob) that is a part of the shaft is attached to the housing so as to be rotatable around the central axis of the shaft. When an operation force for rotating the rotating member is applied, the shaft and the end effector rotate together with the rotating member relative to the housing with the center axis of the shaft serving ...
