Abstract

The present invention is related to a suction device especially designed for endoscopic instruments, including at least two cylindrical suction ports located at both sides of the distal end of the endoscopic instrument. Each suction port has inside and next to the distal end thereof at least one sharp traversing blade. Each suction port is connected to a suction line in turn connected to a suction pump. The external end of said suction line is connected to a disposal recipient into which the debris, blood, coagula, etc. removed from the surgical site will be disposed.

Claims

1. Suction device for endoscopic instruments, including suction ports located at the distal end of the endoscopic instrument;

said suction port includes at least one sharp traversing blade; and

each suction port is connected to a suction line in turn connected to a suction pump;

the external end of said suction line is connected to a disposal recipient.

2. The suction device for endoscopic instruments, in accordance with claim 1, wherein the instrument includes at least two cylindrical suction ports.

3. The suction device for endoscopic instruments, in accordance with claim 2, wherein said suction ports are located at both sides of the distal end of the instrument.

4. The suction device for endoscopic instruments, in accordance with claim 1, wherein the instrument is an endoscopic biopsy forceps.

5. The suction device for endoscopic instruments, in accordance with claim 1, wherein the instrument is an endoscopic scissor

6. The suction device for endoscopic instruments, in accordance with claim 1, wherein the device has four suction ports surrounding the distal end of the endoscopic instrument.

7. The suction device for endoscopic instruments, in accordance with claim 1, wherein into said disposal recipient debris, blood, coagula removed from the surgical site are disposed.

8. The suction device for endoscopic instruments, in accordance with claim 1, wherein inside each suction port a diametrically disposed sharp blade defines a cutting means inside said port capable of cutting any debris, coagula or the like removed from the surgical field during the endoscopic procedure.

9. The suction device for endoscopic instruments, in accordance with claim 1, wherein said ports are connected to two independent parallel suction tubes which are part of the suction line.

10. The suction device for endoscopic instruments, in accordance with claim 1, wherein the suction lines are connected to a disposal bag.

11. The suction device for endoscopic instruments, in accordance with claim 10, wherein the disposal bag is especially designed for containing and disposing biological material.

12. The suction device for endoscopic instruments, in accordance with claim 4, wherein the endoscopic biopsy forceps includes at its distal end two movable grabbing jaws pivotally connected to the distal end, being said jaws connected through a commanding cable to a control device.

13. The suction device for endoscopic instruments, in accordance with claim 12, wherein said control device comprises a mechanical piston linearly movable on longitudinal tracks and a manipulation handle.

14. The suction device for endoscopic instruments, in accordance with claim 5, wherein said endoscopic scissor includes at its distal end two movable blades pivotally connected to the distal end, and said blades are connected through a commanding cable to a control device.

15. The suction device for endoscopic instruments, in accordance with claim 14, wherein said control device comprises a mechanical piston linearly movable on longitudinal tracks, and a manipulation handle.

16. The suction device for endoscopic instruments, in accordance with claim 1, wherein the instrument is one of the following:

clips, lups, injectors, polypectomy snare, ERCP catheters, graspers.

17. The suction device for endoscopic instruments, in accordance with claim 1, wherein the instrument is an endoscopic scissor

18. A suction method for endoscopic procedures, comprising the steps of:

a) introducing an endoscopic instrument into the patient'"'"'s stomach transorally, including said instrument suction ports at its distal end;

b) activating the control command located at the instrument external end to open the instrument;

c) approaching the instrument to the stomach section to be studied;

d) activating a suction pump connected to the suction ports;

e) creating a suction effect in the suction ports around the instrument grabbing the stomach tissue;

f) removing blood through the suction ports while the instrument grabs the tissue;

g) transferring blood, coagula and debris sucked by the suction port from the surgical site are to a disposal bag.

19. The method of claim 18, wherein the instrument is an endoscopic biopsy forceps.

20. The method of claim 18, wherein the instrument is one of the following:

scissors, clips, lups, injectors, polypectomy snare, ERCP catheters, graspers.
