Embodiment Construction

[0049] In the clamp device for living tissue (hereinafter simply referred to as "clamp device") and the clamp of the present invention, the so-called front end side refers to the living body tissue side in use state, and the so-called base end side refers to the biological tissue side. the opposite side of the body tissue. A clamp according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3 . As shown in FIGS. 1 and 2 , the pliers 10 of this example include a pliers main body 1 obtained by bending an elongated metal leaf spring at a central portion, and a cylindrical clip ring 2 . The clamp main body 1 includes clamping parts 3 and 3 for clamping living tissue at the front end, a base end part 4 showing a substantially U-shaped cross-section, and two self-expanding parts extending from the base end part 4 at the front end. Wrist 11, 11. The width dimension w of the metal leaf spring constituting the clamp main body is limited so that i...

Abstract

A clipping instrument for biological tissues equipped with an outer casing which can be inserted into a biological cavity, an operating member freely passed through the outer casing, an operating wire freely passed through the operating member, a self-opening holder which can be opened and closed by the action of the operating member attached to the edge of the operating wire, and a self-opening clip having a clipping member for clipping a biological tissue which is attached to the edge of the holder in a detachable manner by opening / closing the holder. Using this clipping instrument, a lesion site can be surely clipped over a long period of time in ligating a breeding site in a biological tissue, stitching a laceration, marking in excision of a mucosal tissue and so on with an endoscope.

Description

[0001] This application is a divisional application of the application with the filing date of March 16, 2004, the application number of 200480006894.X, and the title of the invention "Clamp and Clamp Device for Biological Tissue". technical field [0002] The present invention relates to a clamp and a clip for living tissue used as an endoscopic treatment tool for ligation of a bleeding part of living tissue, suturing of a wound, and marking of mucosal tissue excision through an endoscope. clamp device. Background technique [0003] Clips used as endoscopic treatment tools are used in many cases, for example, to ligate a bleeding site through an endoscope, to suture a wound, or to use as a marker for mucosal resection. The clamp device for living tissue disclosed in JP Real Opening No. 62-170010 is shown in FIG. The connecting plate 803 which can be attached and detached to the operation wire of the hook is attached to the front end which is not shown in figure. When the ...
