Abstract

A trocar tube incorporating integral irrigation and aspiration capabilities with positioning control. These capabilities can be used in conjunction with endoscopic tools which can be fed through the trocar housing. Specifically, the invention can be used to clean the lens of a laparoscope while it is in place in the trocar tube to eliminate the need for removal of the laparoscope for cleansing. The trocar tube telescoping tip permits independent control of the position of irrigation and aspiration while other tools are in use. Trocar tube channels in the wall of the trocar tube enable fluids to be fed to the distal end of the trocar tube, and enable material to be aspirated from the distal end of the trocar tube. The trocar tube channels are connected to a fluid source and an aspirating device. Aspiration and fluid flow are controlled by a foot pedal or other device that allows hands-free control. The specific improvements in endoscopic procedures afforded by this device inhere in the ability to leave irrigation and aspiration capabilities in place throughout an endoscopic procedure, the ability to supply irrigation and aspiration capabilities to various types of endoscopic tools, including existing laparoscopic tools without self-cleaning capabilities, the ability to direct irrigation and aspiration flow, the minimization of the need to place and remove multi-purpose tools during the procedure.

Claims

1. A trocar tube comprising:

a tubular member having flexible wall, a proximal end and a distal end;

at least one tube channel disposed axially within said wall;

said channel capable of supplying irrigation or aspiration to the distal end of the tubular member.

2. A trocar tube of claim 1, further comprising a trocar tube channel telescoping tip in fluid communication with said tube channel.

3. A trocar tube according to claim 2 further comprising means for positioning said telescoping tip within a patient.

4. A trocar tube according to claim 2 further comprising a wire mechanically linked to said telescoping tip for controlling said telescoping tip.

5. A trocar tube according to claim 2 further comprising a diverter near a distal end of said telescoping tip for directing flow of a fluid passing through said telescoping tip.

6. A trocar tube according to claim 1, wherein said proximal end of said tubular member is enlarged relative to said distal end of said tubular member.

7. A trocar tube according to claim 1, further comprising a control valve attached to a proximal end of said tube channel.

8. A trocar tube according to claim 1, wherein said control valve comprises one of a foot pedal and a knee pedal.

9. A trocar tube according to claim 2, further comprising a flange at a distal end of said tube channel and a flange at a proximal end of said telescoping tip.

10. A trocar comprising:

a tubular member having an elongated tubular wall, a proximal end and a distal end;

a suction channel connected to said tubular member along a length of said tubular wall; and

an irrigation channel connected to said tubular member along a length of said tubular wall.

11. A trocar according to claim 10 further comprising a telescoping tip connected to a distal end of said suction channel.

12. A trocar according to claim 11 further comprising a telescoping tip connected to a distal end of said irrigation channel.

13. A trocar according to claim 11 further comprising means for controlling said telescoping distal end ofsaid suction channel.

14. A trocar according to claim 11, further comprising a flange at a distal end of said suction tube a flange at a proximal end of said telescoping tip connected to said suction tube.

15. A trocar according to claim 10 further comprising a telescoping tip connected to a distal end of said irrigation channel.

16. A trocar according to claim 10 wherein said suction channel is formed within said tubular wall of said trocar.

17. A trocar comprising:

a tubular member having an elongated tubular wall, a proximal end and a distal end; and

a plurality ofchannels formed within said tubular wall.

18. A trocar according to claim 17, wherein at least one of said plurality of channels formed within said tubular wall extends from said proximal end ofsaid tube to said distal end of said tube.
