Abstract

Provided is a bendable treatment instrument that enables an individual doctor who is performing an endoscopic procedure to reliably and intuitively manipulate forceps, a knife, or the like. A bendable treatment instrument ( 1 ) includes a mechanism connecting, via a flexible tube body ( 4 ) encasing a transmission member, a bending section ( 3 ) configured to perform a bending action and a manipulation member ( 8 ) configured to receive a manipulation with respect to the bending section ( 3 ) from an operator. The mechanism is capable of transmitting a manipulation by the manipulation member ( 8 ) to the bending section ( 3 ). The bendable treatment instrument further includes a support member ( 7 ) configured to support the manipulation member ( 8 ) while clasping the flexible tube body ( 4 ), and a rotation support member ( 11 ) configured to support the manipulation member ( 8 ) so as to allow the manipulation member ( 8 ) to axially rotate with respect to the flexible tube body ( 4 ) at the support member ( 7 ).

First claim

1 . A bendable treatment instrument, comprising a mechanism connecting, via a flexible tube body encasing a transmission member, a bending section configured to perform a bending action and a manipulation member configured to receive a manipulation with respect to the bending section from an operator, the mechanism being capable of transmitting a manipulation by the manipulation member to the bending section, the bendable treatment instrument further comprising:
a support member configured to support the manipulation member while clasping the flexible tube body; and a rotation support member configured to support the manipulation member with respect to an axis of the flexible tube body at the support member so as to allow an axis of the manipulation member to axially rotate about the axis of the flexible tube body.

2 . The bendable treatment instrument according to claim 1 , further comprising a lock member configured to inhibit or to permit axial rotation of the manipulation member at the rotation support member.

3 . The bendable treatment instrument according to claim 1 , wherein the support member is configured to stand upright from a predetermined base.

4 . The bendable treatment instrument according to claim 1 , wherein the support member comprises a sliding mechanism configured to slide on the predetermined base.

5 . The bendable treatment instrument according to claim 1 , wherein the flexible tube body is encased in an outer tube fixed to the base.

6 . The bendable treatment instrument according to claim 1 , wherein forceps or a high-frequency knife is provided at a tip end of the bending section.

7 . The bendable treatment instrument according to claim 1 , wherein the flexible tube body has an outer diameter that is smaller than 2.8 mm.

8 . The bendable treatment instrument according to claim 2 , wherein the support member is configured to stand upright from a predetermined base.

9 . The bendable treatment instrument according to claim 2 , wherein the support member comprises a sliding mechanism configured to slide on the predetermined base.

10 . The bendable treatment instrument according to claim 2 , wherein the flexible tube body is encased in an outer tube fixed to the base.

11 . A bendable treatment instrument, comprising a mechanism connecting, via a flexible tube body encasing a transmission member, a bending section configured to perform a bending action and a manipulation member configured to receive a manipulation with respect to the bending section from an operator, the mechanism being capable of transmitting a manipulation by the manipulation member to the bending section, the bendable treatment instrument further comprising:
a support member configured to support the manipulation member; and a rotation support member configured to support the manipulation member at the support member so as to allow an axis of the manipulation member to axially rotate about an axis of the flexible tube body.

12 . The bendable treatment instrument according to claim 11 , further comprising a lock member configured to inhibit or to permit axial rotation of the manipulation member at the rotation support member.

13 . The bendable treatment instrument according to claim 11 , wherein the support member is configured to stand upright from a predetermined base.

14 . The bendable treatment instrument according to claim 11 , wherein the support member comprises a sliding mechanism configured to slide on the predetermined base.

15 . The bendable treatment instrument according to claim 11 , wherein the flexible tube body is encased in an outer tube fixed to the base.

16 . The bendable treatment instrument according to claim 11 , wherein forceps or a high-frequency knife is provided at a tip end of the bending section.

17 . The bendable treatment instrument according to claim 11 , wherein the flexible tube body has an outer diameter that is smaller than 2.8 mm.

18 . The bendable treatment instrument according to claim 12 , wherein the support member is configured to stand upright from a predetermined base.

19 . The bendable treatment instrument according to claim 12 , wherein the support member comprises a sliding mechanism configured to slide on the predetermined base.

20 . The bendable treatment instrument according to claim 12 , wherein the flexible tube body is encased in an outer tube fixed to the base.
