Abstract
Abstract A clip member of substantially a figure "eight" shape is detachably attached to an instrument body. The instrument body has an outer flexible tube, an actuating tubular member inserted into the outer tube, and a wire inserted into the actuating tubular member. A holder is detachably mounted through a guide member to the forward end portion of the actuating member. To the forward end of the wire is secured a hook member for anchoring the clip member. A pair of clamping portions of the clip member is opened by forcefully engaging a pair of offset portions of the clip member with the inner surface of the holder, and closed by forcefully engaging a pair of intersecting portions with the inner surface of the holder. As a result, any affected portion of a body cavity of a human being is clipped by the clip member associated with the holder. The clip member, together with the holder, is left within the body cavity with the clamping portions thereof closed.

Claim 1
Independent Claim
328 words
A surgical instrument for clipping any affected portion of a body cavity of a human being, comprising a clip member formed into a substantially figure "eight" shape and having a rear end portion, a pair of offset portions having one end connected to the rear end portion and the other end extending away from the longitudinal axis of the clip member, a pair of portions respectively connected at one end to the opposite ends of the offset portions and intersecting each other, and a pair of clamping portions respectively connected to the opposite ends of the intersecting portions; an instrument body through an interior of which the clip member is introduced into the body cavity; a hook member mounted within the instrument body so as to anchor the rear end portion of the clip member; first actuating member for moving the hook member anywhere between a first position in which the hook member is exposed and a second position in which the hook member is retracted within the instrument body; engaging means adapted to be forcefully engaged with the offset portions of the clip member, when the hook member is retracted a predetermined distance from the first position, to cause the offset portions to be urgingly compressed to move the clamping portions of the clip member to an opened position, adapted to be forcefully engaged with the intersecting portions of the clip member, when the hook member is further retracted by the first actuating means, to cause the clamping portions of the clip member to be closed to clip the affected portion of the body cavity, and adapted to be left, together with the clip member within the body cavity when the clip member associated therewith is separated from the instrument body; and second actuating means for moving the engaging means relative to the hook member anywhere between a first position in which the engaging means is exposed and a position in which the engaging means is retracted.

A surgical instrument for clipping any affected portion of a body cavity of a human being, comprising a clip member formed into a substantially figure "eight" shape and having a rear end portion, a pair of offset portions having one end connected to the rear end portion and the other end extending away from the longitudinal axis of the clip member, a pair of portions respectively connected at one end to the opposite ends of the offset portions and intersecting each other, and a pair of clamping portions respectively connected to the opposite ends of the intersecting portions; an instrument body through an interior of which the clip member is introduced into the body cavity; a hook member mounted within the instrument body so as to anchor the rear end portion of the clip member; first actuating member for moving the hook member anywhere between a first position in which the hook member is exposed and a second position in which the hook member is retracted within the instrument body; engaging means adapted to be forcefully engaged with the offset portions of the clip member, when the hook member is retracted a predetermined distance from the first position, to cause the offset portions to be urgingly compressed to move the clamping portions of the clip member to an opened position, adapted to be forcefully engaged with the intersecting portions of the clip member, when the hook member is further retracted by the first actuating means, to cause the clamping portions of the clip member to be closed to clip the affected portion of the body cavity, and adapted to be left, together with the clip member within the body cavity when the clip member associated therewith is separated from the instrument body; and second actuating means for moving the engaging means relative to the hook member anywhere between a first position in which the engaging means is exposed and a position in which the engaging means is retracted.
Claim 3
Dependent Claim
19 words
A surgical instrument according to claim 1, in which said clip member is made of a sheet of metal.
Claim 4
Dependent Claim
29 words
A surgical instrument according to claim 1, in which the clamping portion of the clip member is wider than the offset portion and intersecting portion of the clip member.
Claim 5
Dependent Claim
31 words
A surgical instrument according to claim 1, in which said clip member is anchored by the hook member and, when retracted to its extreme extent, is received within the instrument body.
Claim 6
Dependent Claim
32 words
A surgical instrument according to claim 1, in which said first actuating means includes a lengthy wire movable within the instrument body and having a free end connected to the hook member.
Claim 7
Dependent Claim
22 words
A surgical instrument according to claim 1, in which said engaging means is a cylindrical member opened at both the ends thereof.
Claim 8
Dependent Claim
50 words
A surgical instrument according to claim 6, in which said second actuating means comprises a lengthy tubular actuating member movable within the instrument body and thin-walled cylindrical guide member opened at both the ends thereof, said cylindrical member being slidably fitted into the forward end portion of the guide member.
Claim 9
Dependent Claim
47 words
A surgical instrument according to claim 7, in which said cylindrical member is stepped in its outer diameter and has a front large diameter portion and a rear small diameter portion, and the small diameter portion is fitted into the forward end portion of the guide member.
Claim 10
Dependent Claim
95 words
A surgical instrument according to claim 8, in which, when the intersecting portions of the clip member are urgingly engaged with the cylindrical member by withdrawing the hook member by virtue of the first actuating means, the offset portion of the clip member are positioned within an inner hole of the guide member and between the forward end of the diameter of the inner hole of the guide member is large enough to allow a clearance to be formed with respect to a junction between the offset portion and intersecting portion of the clip member.
Claim 11
Dependent Claim
49 words
