ABSTRACT:
Apparatus for ligating blood vessels, nerves or other anatomical structures, such as Fallopian tubes, utilizing a modified form of a standard hemostat, including a removable pair of hemostat jaw inserts of non-toxic, substantially rigid material, each releasably secured to a jaw of the hemostat, each insert having removably formed therein at least one clip member, locking structure contained by at least one of said clip members adapted lockingly to engage the other of said clip members, whereby the jaws of the hemostat can be opened to any desired width and then closed, locking the clip members to form a ligating clip over or in a blood vessel or other anatomical structure and opening the jaws causes said joined clip members to break away from the inserts.
In a preferred embodiment of the invention, fail-safe structure is provided to ensure that the clip members break cleanly away from the inserts.
Apparatus comprising a modified hemostat, wherein said insert and clip members form a planar extension of the inner surface of the hemostat jaw.
