Abstract

Abstract A surgical clip is formed from a resilient strip piece and comprises a pair of elongated clip legs for clipping a blood vessel therebetween, and an annular bight portion connecting said clip legs at their respective one ends, said clip legs having opposed surfaces which are normally in contact with each other substantially over their whole lengths owing to the resilience of said bight portion which can be opened when the inner diameter of said annular bight portion is forcibly spread.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 247 words
A blood circulation stopping clip assembly comprising a plurality of elemental blood circulation stopping clips each elemental clip being formed of a resilient strip piece and comprising a pair of elongated clip legs for clipping a blood vessel therebetween and an annular bight portion connecting said clip legs at their respective one ends, each of said clip legs being formed in an elongated tongue shape having tapered side edges each of said clip legs having opposed surfaces which are normally urged to be in contact with each other substantially over their whole areas owing to the resilience of said bight portion and can be opened when the inner diameter of said annular bight portions forcibly spread; and a connection clip for supporting and connecting said plurality of elemental clips in parallel and in a spaced relationship, said connection clip being formed of a resilient strip piece and comprising a pair of elongated clip legs for clipping said elemental clips at their annular bight portions and an annular bight portion connecting said clip legs of said connection clip at their respective one ends, said clip legs of said connection clip having opposed surfaces which are normally urged to be in contact with each other owing to the resilience of said bight portion to hold said annular bight portions of said elemental clips while they can be opened to release said elemental clips when the inner diameter of said annular bight portion of said connection clip is forcibly spread.
Claim 2
Dependent Claim 247 words
A blood circulation stopping clip assembly comprising a plurality of elemental blood circulation stopping clips each elemental clip being formed of a resilient strip piece and comprising a pair of elongated clip legs for clipping a blood vessel therebetween and an annular bight portion connecting said clip legs at their respective one ends, each of said clip legs being formed in an elongated tongue shape having tapered side edges each of said clip legs having opposed surfaces which are normally urged to be in contact with each other substantially over their whole areas owing to the resilience of said bight portion and can be opened when the inner diameter of said annular bight portions forcibly spread; and a connection clip for supporting and connecting said plurality of elemental clips in parallel and in a spaced relationship, said connection clip being formed of a resilient strip piece and comprising a pair of elongated clip legs for clipping said elemental clips at their annular bight portions and an annular bight portion connecting said clip legs of said connection clip at their respective one ends, said clip legs of said connection clip having opposed surfaces which are normally urged to be in contact with each other owing to the resilience of said bight portion to hold said annular bight portions of said elemental clips while they can be opened to release said elemental clips when the inner diameter of said annular bight portion of said connection clip is forcibly spread.
Claim 3
Dependent Claim 40 words
A blood circulation stopping clip assembly as defined in claim 1, in which each said clip legs of said connection clip has a width smaller than the inner diameter of said annular bight portion of each of said elemental clips.
Claim 4
Dependent Claim 36 words
A blood circulation stopping clip assembly as defined in claim 1, in which said clip legs of said connection clip provided at their free ends with lock means for preventing said leg portions from being opened.
Claim 5
Dependent Claim 58 words
A blood circulation stopping clip assembly as defined in claim 1, in which said elemental clips are supported and connected by said connection clip in such a manner that one elemental clip is held at a fixed portion while the other elemental clip is held so as to be slidable along said clip legs of said connection clip.
Claim 6
Dependent Claim 44 words
A blood circulation stopping clip assembly as defined in claim 1, in which said clip legs of said connection clip are insertable into said bight portions of said elemental clips and engageable with the inner peripheries of said bight portions of said elemental clips.
Claim 7
Dependent Claim 255 words
A combination of a blood circulation stopping clip and a forceps for opening and closing said clip in which said blood circulation stopping clip is formed of a resilient strip piece and comprises a pair of elongated clip legs for clipping a blood vessel therebetween and an annular bight portion connecting said clip legs at their respective one ends, each of said clip legs being formed in an elongated tongue shape having tapered side edges, each of said clip legs having opposed surfaces which are normally urged to be in contact with each other substantially over their whole area owing to the resilience of said bight portion which can be opened when the inner diameter of said bight portion is forcibly spread and said forceps for opening and closing said clip is provided with a pair of frusto-conical tips at its working ends, said frusto-conical tips having round end surfaces opposed to each other and being engageable with said bight portion of said clip to forcibly spread said bight portion when said forceps is closed, the outer diameter of the frusto-conical tips of said forceps being slightly greater than the inner diameter of the annular bight portion of said blood circulation clip so that the opposed surfaces of said clip legs of said clip may be opened by a fixed angle at a point where the smaller round end surfaces of the frusto-conical tips contact each other whenever the frusto-conical tips of said forceps are inserted into said annular bight portion to the fullest extent.
Claim 8
Dependent Claim 255 words
A combination of a blood circulation stopping clip and a forceps for opening and closing said clip in which said blood circulation stopping clip is formed of a resilient strip piece and comprises a pair of elongated clip legs for clipping a blood vessel therebetween and an annular bight portion connecting said clip legs at their respective one ends, each of said clip legs being formed in an elongated tongue shape having tapered side edges, each of said clip legs having opposed surfaces which are normally urged to be in contact with each other substantially over their whole area owing to the resilience of said bight portion which can be opened when the inner diameter of said bight portion is forcibly spread and said forceps for opening and closing said clip is provided with a pair of frusto-conical tips at its working ends, said frusto-conical tips having round end surfaces opposed to each other and being engageable with said bight portion of said clip to forcibly spread said bight portion when said forceps is closed, the outer diameter of the frusto-conical tips of said forceps being slightly greater than the inner diameter of the annular bight portion of said blood circulation clip so that the opposed surfaces of said clip legs of said clip may be opened by a fixed angle at a point where the smaller round end surfaces of the frusto-conical tips contact each other whenever the frusto-conical tips of said forceps are inserted into said annular bight portion to the fullest extent.
