Benefits of technology

[0014] Also, the present invention provides a clip holder having one or two or more clip accommodating grooves for accommodating a clip comprising a self-opening clip body having a clipping part on a tip and equipped with

Problems solved by technology

However, it is difficult to fill into a cavity of a small clip securing ring 802 from a viewpoint of manufacturing and, upon clipping a biological tissue, there is a problem that a fixing agent 804 filled into a cavity of a clip securing ring 802 is peeled and fallen.
Since in this clipping equipment, a clip is directly mounted on a hook provided on a tip of an operating wire, there is a problem that, when a clip is dwelled, a clipping equipment must be moved forwardly and backwardly, and left and right in order to remove a clip from a hook, thus, a way to use it is troublesome.
Although this clipping equipment 900 improved troublesome operation of removing a clip from a hook, since a connecting plate 903 is engaged with an operating wire 901 also after clip dwelling, a connecting plate 903 must be removed after taken out from an endoscope, and there is a problem of disposal of a connecting plate 903 which has become an unnecessary part.
In addition, there is a problem that, since a connecting plate 903 is small, it is sucked into a sucking port of an endoscope rarely, and this becomes a cause for worse suction.
In addition, as a common problem of clipping equipments described in JP-A No. 50-75797 and JP-U No. 2-6011, there is a problem that, when a clip is mounted on a clipping equipment, since a hook is a cantilevered type, balance is worse, and a clip is easily detached from a hook.
However, since attachment of a clip and operation of opening are performed by a ratchet mechanism, there is a problem that, in order to assuredly stop a clip at an intended position, an operator must perform position adjusting operation while seeing a clip, and operation is troublesome.
Further, in many cases where a lesion must be grasped with a clip, it is difficult to perform rapid operation.
Such the operation needs a skill and is troublesome.

Embodiment Construction

[0050] In a clipping equipment for a biological tissue (hereinafter, simply also referred to as “clipping equipment”) of the present invention and a clip, a tip side refers to a biological tissue side in the use state, and a basal side refers to a side opposite to a biological tissue. A clip in an embodiment of the present invention will be explained by referring to FIG. 1 to FIG. 3. As shown in FIG. 1 and FIG. 2, a clip 10 of the present example comprises a clip body 1 obtained by bending an elongate metal plate spring at a central part, and a cylindrical securing ring 2. A clip body 1 comprises clipping parts 3,3 for clipping a biological tissue on a tip, a basal part 4 exhibiting a generally U-shaped cross section, and twin-arm parts 11,11 having self-opening property on a tip which extend from a basal part 4. Since a metal plate spring constituting a clip body is movably inserted in a cavity of an operating member described later, a width size w thereof is restricted.

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 clip and a clipping equipment for biological tissues, which are used as a treating equipment for an endoscope for ligating a bleeding site in a biological tissue, stitching a laceration, and marking in excision of a mucosal tissue with an endoscope. BACKGROUND TECHNIQUE [0002] A clip used as a treating equipment for an endoscope is used in many cases, such as ligating a bleeding site, stitching a laceration, and marking in excision of a mucosal tissue with an endoscope. A clipping equipment for biological tissues disclosed in Japanese Utility Model Application Laid-Open (JP-U) No. 62-170010 is constructed of a clip 801 having opening habit, a clip securing ring 802 for closing a clip tip part, and a connecting plate 803 which is detachable on an operating wire in which a hook is attached to a tip (not shown), as shown in FIG. 35. In this clipping equipment 800 for biological tissues, when the clipping equipment holds a biolog...
