Abstract

A method and device for cutting and sealing of disposable multilumen tubing is disclosed. The method comprises providing a first surface and an opposite second surface, placing a portion of the multilumen tubing between the first and the second surface and applying heat and pressure to at least one of the first and the second surface so as to plastically deform and cut the said portion of the multilumen tubing and to heat-seal the cut ends thereof. The device for cutting and sealing comprises a first jaw and juxtaposed therewith a second jaw, said first and said second jaw are provided with respective first and second surface. The device further comprises biasing member exerting pressure on at least one of the said first and the second surface and a source of energy suitable for heating of at least one of the said first and the second surface.

Claims

1. A method for cutting and sealing of a disposable multilumen tubing used with an endoscopic apparatus, said method comprising:

a) providing a first surface and a second surface positioned opposite said first surface,

b) placing a portion of the multilumen tubing between the first and the second surface,

c) applying heat and pressure to at least one of the first and the second surface so as to plastically deform and cut the said portion of the multilumen tubing and to heat-seal the cut ends thereof.

2. The method for cutting and sealing as defined in claim 1, in which said heat and pressure are applied simultaneously.

7. The method for cutting and sealing as defined in claim 1, comprising supplying of electrical power for heating of at least one of the first and the second surface.

8. The method for cutting and sealing as defined in claim 7, in which said electrical power is supplied to the second surface.

9. The method for cutting and sealing as defined in claim 1, in which said first and second surface are made of an electrically resistant material.

10. The method for cutting and sealing as defined in claim 1, in which said first and second surface are flat.

3. The method for cutting and sealing as defined in clam 2, comprising relative displacement of the first and the second surface before applying the heat and pressure to provide room for placement of the portion of the multilumen tubing between the first and the second surface.

4. The method for cutting and sealing as defined in claim 3, comprising displacement of the first surface with respect to the second surface.

5. The method for cutting and sealing as defined in claim], in which said pressure is applied by a biasing member.

6. The method for cutting and sealing as defined in claim 5, in which said pressure is applied to the first surface.

11. A device for cutting and sealing of a disposable multilumen tubing used with an endoscopic apparatus, said device comprising:

a) a first jaw and a second jaw juxtaposed to said first jaw, said first jaw and second jaw being relatively displaceable with respect to each other, said first and said second jaw being provided with respective first and second surfaces,

b) a biasing member bringing the first jaw in proximity with the second jaw and exerting pressure on at least one of the said first and the second surfaces,

c) a source of energy for heating of at least one of the said first and the second surface.

12. The device for cutting and sealing as defined in claim 11, wherein the first jaw is displaceable with respect to the second jaw.

13. The device for cutting and sealing as defined in claim 12, wherein said source of energy supplies electrical power to at least one of the first and second surface, wherein said first and second surface being made of electrically resistant material.
