Patent ID: 7736363

Claim:
A hemostatic forceps for an endoscope used together with a flexible endoscope, comprising: an operation dud part inserted in a channel for a treatment tool formed in an insert unit of the endoscope; a pair of clamp pieces connected to a distal side of the operation duct part, which is openable and closeable; and an operation part connected to a bottom side of the operation dud part, which controls opening-and-closing action of the pair of clamp pieces, wherein a support section supporting the pair of clamp pieces so that the pair of clamp pieces is rotatable and changeable in their distal directions, is provided to a bottom side of the pair of clamp pieces; clamp faces of the pair of clamp pieces facing each other can be parallel to each other while having a gap therebetween over the entire faces even when the clamp faces are not completely closed; shapes of the pair of clamp pieces are fanned so that widths of the pair of clamp pieces gradually decrease in a direction from a side of the support section thereof to a side of distal parts of the pair of the clamp pieces; a length of the pair of clamp pieces at an arbitrary location along the direction from the side of the support section to the side of the distal parts, times a width of the pair of clamp pieces at the same location, is set to be sufficiently constant; and in a state where the pair of clamp pieces is completely closed, width of a gap formed between peripheral edges of the clamp faces of the pair of clamp pieces gradually increases throughout the entire clamp faces from the side of the distal parts to the side of the support section, and distal ends of the clamp faces contact with each other so that there is no space between the distal ends of the clamp faces.
