no. 1 Embodiment approach
[0031] 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. figure 1 The shown treatment device 1 has a defined axis of rotation R (length axis). Here, the side along the direction of the predetermined rotation axis R 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).
[0032] The treatment instrument 1 includes a housing 2 , a shaft (sheath) 3 protruding from the housing 2 , and an end effector 5 . The shaft 3 and the end effector 5 form a rotary element (rotary element) 6 that rotates with respect to a predetermined rotational axis R of the housing 2 . That is, the rotating element 6 has the shaft 3 and the end effector 5 .
[0033] A central axis C is defined at the shaft 3 . The shaft 3 extends from the proximal side to the ...
no. 2 Embodiment approach
[0103] Next, use Figure 14A and Figure 14B The second embodiment will be described. This embodiment is a modified example of the first embodiment including various modified examples. Members that are the same as those described in the first embodiment or have the same functions are given the same reference numerals as much as possible, and detailed descriptions are omitted. illustrate.
[0104] In the first embodiment including the first modification to the seventh modification, an example in which the end effector 5 can actively move at the distal end of the shaft 3 has been described. In addition, a pair of holding pieces 16, 17 of the end effector 5 (refer to figure 1 and figure 2 ) is described as an example where it can be opened and closed relatively. Here, an example in which the end effector 5 is integrally formed on the distal end of the shaft 3 and the end effector 5 is bent relative to the shaft 3 has been described. That is, in the present embodiment, the ...
no. 3 Embodiment approach
[0110] Next, use Figure 15 ~ Figure 17 The third embodiment will be described. This embodiment is a modified example of the first embodiment including the first modified example to the seventh modified example and a modified example of the second embodiment, and the same members as those described in the first embodiment and the second embodiment are described. Or components having the same function are denoted with the same reference signs as much as possible, and detailed descriptions are omitted.
[0111] In the first embodiment, an example in which the rotating member 25 is arranged at the distal end portion of the casing main body 11 has been described. Here, if Figure 15 As shown, an example in which a part of the rotary knob 26A of the rotary member 25 protrudes from the side of the housing main body 11 will be described.
[0112] In the first embodiment, if Figure 4 and Figure 5 As shown, an example in which the rotating member 25 is supported at one position ...
