Patent ID: 8465501

Claim:
A ligating apparatus for ligating a body tissue, said apparatus comprising: a clip that comprises freely openable/closeable arm portions and that is configured to ligate a body tissue with the arm portions; a clip connecting member that comprises a connecting member end portion connected continuously to a clip base portion; a clip holding member that comprises a communicating hole for causing the clip and the clip connecting member to be inserted into the communicating hole; an operating wire that connects to a wire connecting portion provided at a connecting member base portion of the clip connecting member and that is configured to perform an operation of pulling the clip connecting member; an inner sheath member that is configured to be extended to enclose the operating wire and that supports the clip holding member at a distal-end portion of the inner sheath member; an outer sheath member that is arranged to cover an outer periphery of the inner sheath member and that is arranged to freely advance and retreat; and first and second movement restricting portion that are configured to restrict movements of the clip holding member with respect to the inner sheath member, wherein the outer sheath member changes a degree of opening of the arm portions by causing the arm portions to abut on an inner peripheral surface of the outer sheath member, wherein the first movement restricting portion restricts a movement of the clip holding member in a direction toward an axially back end side of the inner sheath member, wherein the second movement restricting portion restricts a movement of the clip holding member in a direction toward an axially distal end side of the inner sheath member, wherein the first movement restricting portion includes catching-surfaces respectively formed on the clip holding member and the inner sheath member to abut against each other, wherein the catching-surfaces include a bottom surface of a conical body portion formed in the clip holding member and an inner sheath bearing surface formed on the distal-end portion of the inner sheath member, wherein the second movement restricting portion includes an elastically bending leg-element extended from the communicating hole of the clip holding member to the inner sheath member, wherein the elastically bending leg-element is spread when the clip connecting member is inserted into the communicating hole, and wherein an end narrowing portion of the inner sheath member is sandwiched by a leg end portion of the leg-element and the bottom surface of the conical body portion.
