Abstract
A medical treatment endoscope includes: a flexible sheath capable of a bending operation; a viewing unit for observing the vicinity of the tip relative to the sheath; an arm section protruding from the tip of the sheath and capable of bending operation; an operation section for operating the arm section; and at least a transmission member, connected to the arm section and the operation section, for transmitting the operation of the operation section to the arm section. The transmission member is detachably connected to the operation section.
Claims9
A medical treatment apparatus comprising:
- an endoscope having a bending part configured to do a first bending motion in a first direction in accordance with a first linear motion of a first transmission member and configured to do a second bending motion in a second direction which is different from the first direction in accordance with a second linear motion of a second transmission member;
- an operation input unit which inputs an operation for actuating the first and the second bending motions in the first and the second direction in the bending part, the operation input unit being configured to be operated by an operator;
- a first axis member which connects and rotatably supports the operation input unit;
- a second axis member crossing the first axis member which connects and rotatably supports the operation input unit;
- a first conversion member being connected to the first axis member, converting a rotation motion of the first axis member to a linear motion, and transmitting the linear motion thereof to the first transmission member;
- a second conversion member being connected to the second axis member at a position distant from the first conversion member, converting a rotation motion of the second axis member to a linear motion, and transmitting the linear motion thereof to the second transmission member;
- a first attaching-detaching mechanism detachably connecting the first conversion member to the first axis member;
- a second attaching-detaching mechanism detachably connecting the second conversion member to the second axis member;
- and
- a connecting member connecting the first conversion member and the second conversion member with the second conversion member being spaced from the first conversion member, wherein
- the first axis member is configured to be rotated by a tilting movement of the operation input unit in the first direction provided by the operator;
- and
- the second axis member is configured to be rotated by a tilting movement of the operation input unit in the second direction provided by the operator.
