Abstract

A multiple clip applicator system for tissue clamping of hemostasis includes clip devices of a train and a flexible sheath. To load the flexible sheath with clip devices, a coupling device is used. A shaft head is positioned on an operating wire in the flexible sheath. A receiving opening is formed in the coupling device, for receiving insertion of the shaft head, for mating by press-fit with the fastening clip device. The shaft head is a selected one of plural shaft heads which are different in a shape according to the plural multiple clip assemblies. The receiving opening is a selected one of plural receiving openings having a shape according to corresponding shapes of the plural shaft heads, and adapted to preventing a second shaft head from entry in a first receiving opening and preventing a first shaft head from entry in a second receiving opening.

Claims

1. A clip package comprising:

a multiple clip assembly having plural clip devices connected with one another in a train by use of claws positioned at distal ends of openable arms, a fastening clip device connected with a final one of said clip devices, and a fitting connector, disposed on said fastening clip device, for mating with a shaft head in a direction transverse to a direction of said train of said clip devices at a distal end of an operating wire for operating said clip devices;

a housing for containing said multiple clip assembly;

a coupling device, including;

a stage portion for introducing said multiple clip assembly from said housing, to enable coupling with a flexible sheath through which said operating wire extends;

a receiving opening, having a form slightly larger than a profile of said shaft head and a portion of said operating wire as viewed in said transverse direction, for receiving insertion of said shaft head and said portion of said operating wire to mate said shaft head with said fitting connector on said stage portion;

wherein said coupling device operates upon pull of said operating wire after mating said shaft head with said fitting connector, to enter said multiple clip assembly from said stage portion into said flexible sheath in a proximal direction thereof.

2. A clip package as defined in claim 1, wherein said multiple clip assembly is a selected one of at least first and second multiple clip assemblies which are different in at least one of a length of said arms and a number of said clip devices in said train;

said shaft head is a selected one of first and second shaft heads which are different in a shape in association with said first and second multiple clip assemblies;

said receiving opening is selected from first and second receiving openings according to said first or second shaft head;

further comprising a prevention device, positioned in at least one of said first and second receiving openings, for preventing said second shaft head from entry in said first receiving opening, and preventing said first shaft head from entry in said second receiving opening.

3. A multiple clip applicator system, including a multiple clip assembly having plural clip devices connected with one another in a train by use of claws positioned at distal ends of openable arms, a fastening clip device connected with a final one of said clip devices, and a fitting connector, disposed on said fastening clip device, for mating with a shaft head in a direction transverse to a direction of said train of said clip devices at a distal end of an operating wire for operating said clip devices, said multiple clip applicator system comprising:

a housing for containing said multiple clip assembly;

a coupling device, including;

a stage portion for introducing said multiple clip assembly from said housing, to enable coupling with a flexible sheath through which said operating wire extends;

a receiving opening, having a form slightly larger than a profile of said shaft head and a portion of said operating wire as viewed in said transverse direction, for receiving insertion of said shaft head and said portion of said operating wire to mate said shaft head with said fitting connector on said stage portion;

wherein said coupling device operates upon pull of said operating wire after mating said shaft head with said fitting connector, to enter said multiple clip assembly from said stage portion into said flexible sheath in a proximal direction thereof;

a handle device for moving said operating wire relative to said flexible sheath with stroke according to a length of said arms and a sequence of said train, to carry out treatment with each one of said clip devices in said multiple clip assembly.

4. A multiple clip applicator system as defined in claim 3, wherein said multiple clip assembly is a selected one of at least first and second multiple clip assemblies which are different in at least one of a length of said arms and a number of said clip devices in said train;

said shaft head is a selected one of first and second shaft heads which are different in a shape in association with said first and second multiple clip assemblies;

said receiving opening is selected from first and second receiving openings according to said first or second shaft head;

further comprising a prevention device, positioned in at least one of said first and second receiving openings, for preventing said second shaft head from entry in said first receiving opening, and preventing said first shaft head from entry in said second receiving opening.

5. A multiple clip applicator system as defined in claim 4, wherein said handle device is a selected one of first and second handle devices which are different in stroke of said shaft head and said operating wire in association with respectively said first and second multiple clip assemblies;

said coupling device is a selected one of first and second coupling devices having respectively said first and second receiving openings.

6. A multiple clip applicator system as defined in claim 5, wherein said shaft head includes:

a first hook projection, having a common shape between said first and second multiple clip assemblies, for engagement with said fitting connector;

a second hook projection having a shape different between said first and second multiple clip assemblies.

7. A multiple clip applicator system as defined in claim 6, wherein said second hook projection is positioned on a proximal side from said first hook projection.

8. A multiple clip applicator system as defined in claim 6, wherein said second hook projection includes at least one peripheral groove of which a position, number or size is different between said first and second multiple clip assemblies;

said prevention device includes an internal projection, formed with each of said first and second receiving openings, for insertion in said peripheral groove.

9. A multiple clip applicator system as defined in claim 6, wherein said second hook projection includes a coil associated with at least one of said first and second multiple clip assemblies, and disposed about a distal end of said operating wire;

said receiving opening has a width for passing said coil.

10. A multiple clip applicator system as defined in claim 6, wherein said second hook projection is in a drum shape, and has a difference between said first and second multiple clip assemblies in at least one of a number, outer diameter and length thereof.

11. A multiple clip applicator system as defined in claim 6, wherein said at least first and second multiple clip assemblies include:

a multiple clip assembly of a standard size;

a multiple clip assembly of a long size having said clip devices of which said arms are longer than said arms in said standard size;

a multiple clip assembly of a short size having said clip devices of which said arms are shorter than said arms in said standard size.

12. A prevention device for preventing mismatch in a multiple clip applicator system;

said multiple clip applicator system including;

a multiple clip assembly having plural clip devices and a fastening clip device, said clip devices being connected with one another in a train by use of claws positioned at distal ends of openable arms, said fastening clip device being connected with a final one of said clip devices;
