Abstract
A remote tubing assembly is provided which includes a remote tubing attachment which is connected at a first end to a surgical suction/irrigation valve and at a second end to either an instrument insert probe, trocar(s), or a handpiece to provide concurrent smoke evacuation, suction and irrigation at an operative site while a surgeon is simultaneously utilizing surgical hand instruments at the operative site. The remote tubing assembly allows for major smoke removal as well as suction and irrigation while utilizing hand instruments. Thus, the present invention allows a surgeon to concentrate on detailed dissection, while keeping the operative field free of smoke and debris.
Claims23
A tubing assembly for supplying concurrent suction and irrigation to an operative site from a remote surgical valve of the type having an irrigation chamber, a suction chamber, and valve controls for controlling irrigation and suction flows through the chambers, said tubing assembly comprising:
- a first tubing member having a first end and a second end, said first tubing member defining a first internal passageway extending from said first end to said second end;
- a second tubing member having a first end and a second end, said second tubing member defining a second internal passageway extending from said first end to said second end of said second tubing member and being isolated from said first internal passageway;
- a valve connection member coupled to said first ends of said first and second tubing members, said valve connection member being shaped to engage the surgical valve, said valve connection member having a first channel fluidly coupling said first passageway and one of the irrigation and suction chambers of the valve and a second channel fluidly coupling said second passageway and the other of the irrigation and suction chambers, wherein said first and second channels are isolated from each other to maintain said first and second internal passageways isolated from each other to permit concurrent irrigation through the irrigation chamber into one of said internal passageways and suction through the other of said internal passageways and the said suction chamber without interference between said first and second internal passageways;
- and
- an instrument connector coupled to said second ends of said first and second tubing members, said instrument connector being shaped to engage separate connector attachments on a surgical instrument used at the operative site and to maintain said first passageway isolated from said second passageway, such that said first and second internal passageways are isolated from each other to permit concurrent irrigation through one of said passageways and suction through the other of said passageways without interference with each other.
A tubing assembly for supplying concurrent suction and irrigation to an operative site from a remote surgical valve, the surgical valve being of the type having an irrigation chamber, a suction chamber, valve controls for controlling irrigation and suction flows through each of the irrigation and suction chambers, and a common channel communicating with the irrigation chamber and suction chamber, said tubing assembly comprising:
- a first tubing member having a first open end and a second open end, said first tubing member defining a first internal passageway extending from said first open end to said second open end;
- a second tubing member having a first open end and a second open end, said second tubing member defining a second internal passageway extending from said first open end to said second open end of said second tubing member and isolated from said first internal passageway;
- a valve attachment member coupled to said first open ends of said first and second tubing member and having a first end and a second end, said first end of said valve attachment member having a first port and a second port isolated from said first port, said first open end of said first tubing member being coupled to and in fluid communication with said first port, said first open end of said second tubing member being coupled to and in fluid communication with said second port, said second end of said valve attachment member being shaped to engage the surgical valve and to maintain said first internal passageway isolated from said second internal passageway, such that irrigation through one of said tubing members is isolated from suction through the other of said tubing members thereby permitting concurrent irrigation and suction through said isolated internal passageways of said tubing members without interference;
- and
- an instrument connector coupled to said second ends of said first and second tubing members, such that irrigation through one of said tubing members is isolated from irrigation through the other of said tubing members thereby permitting concurrent irrigation and suction through separate internal passageways of said tubing members without interference.
A tubing assembly for supplying concurrent suction and irrigation to an operative site from a remote surgical valve, the surgical valve having an irrigation chamber, a suction chamber, and a common channel communicating with the irrigation chamber and suction chamber, said tubing assembly comprising:
- a first tubing member having a first end and a second end, said first tubing member defining a first internal passageway extending from said first end to said second end;
- a second tubing member having a first end and a second end, said second tubing member defining a second internal passageway extending from said first end to said second end of said second tubing member;
- a valve attachment member having a first end and a second end, said first end defining a first internal port and a second internal port, the first end of said first tubing member disposed within said first internal port and the first end of said second tubing member disposed within said second internal port, the second end of said valve attachment member being shaped for removable connection to the surgical valve;
- a rod member having a first end and a second end and defining a passageway therebetween, said second end of said rod defining a boss member, the second end of said rod being shaped to be disposed within a surgical valve to isolate the suction chamber from the irrigation chamber, said first end of said rod being disposed within said attachment member to isolate said first internal port from said second internal port to isolate said first passageway from said second passageway, and to provide communication between said first internal passageway and the passageway of said rod;
- a first luer member disposed at the second end of such first tubing member;
- and
- a second luer member disposed at the second end of said second tubing member, at least one of said first luer and said second luer being shaped for removable connection to a surgical instrument used at the operative site.
