Embodiment Construction

[0049] In the living tissue clamping device of the present invention (hereinafter simply referred to as "clamping device") and the clamp, the term "front end side" refers to the side of the body tissue in use, and the term "proximal end side" refers to a side that is close to the biological tissue. 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 . Figure 1 and figure 2 As shown, the clamp 10 of this example includes a clamp body 1 and a cylindrical clamp ring 2 obtained by bending an elongated metal leaf spring at the center. The clamp main body 1 includes gripping parts 3 and 3 for gripping living tissue at the distal end; a proximal end part 4 showing a substantially U-shaped cross section; Wrist 11, 11. The width dimension w of the metal leaf spring constituting the clamp main body is restricted so as to be able to be inserted into the cavity of the later-described operati...

Abstract

A clipping instrument for biological tissues equipped with an outer tube which can be inserted into a biological cavity, an operating member freely passed through the outer tube, an operating wire freely passed though 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 clop having a clipping member for clopping a biological tissue which is attached to the edge of the holder in a detachable manner by opening / closing the holder. Using this clopping 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, making in excision of a mucosal tissue and so on with an endoscope.

Description

technical field [0001] The present invention relates to a clamp used as an endoscopic treatment tool for ligation of a bleeding site of living tissue, suturing of a laceration, and a marker at the time of mucosal tissue excision by an endoscope, and a clamp for living tissue Clamp device. Background technique [0002] A clamp used as an endoscopic treatment tool is used in many cases, for example, for ligation of a bleeding site through an endoscope, for suturing a laceration, or as a marker for mucosal excision. The gripping device for living tissue disclosed in JP Kokai Sho 62-170010 is as follows: Figure 35 As shown, it consists of a clamp 801 having an opening habit, a clamp tightening ring 802 closing the front end of the clamp, and a connecting plate 803 attachable to and detachable from an operation wire having a hook attached to the front end (not shown). In this living tissue clamp device 800, when clamping a living tissue such as a lesion, the connecting plate 80...
