Abstract:
A smoke evacuation apparatus adapted to receive and hold a surgical device which may produce smoke, the device having proximal and distal ends, and which apparatus can be connected to a suction tube; the apparatus comprising:an elongated unitary holder formed of elastic material for receiving a device, the unitary holder having proximal and distal ends and including an upper U-shaped cradle having a first end at the proximal end of the unitary holder and a second end spaced inwardly of the distal end of the unitary holder, a conically shaped portion for capturing a distal end portion of a device, the conically shaped portion being spaced inwardly of the distal end of the unitary holder, the conically shaped portion having a large diameter proximal end adjacent the distal end of the cradle and a small diameter distal end, an oval shaped lumen located adjacent the cradle and the conically shaped portion, and an elongated tubular opening at the distal end of the unitary holder through which smoke may pass; and a tubular substantially rigid back end piece provided with a proximal end portion, a distal end portion, and an intermediate retaining element which may bear against the proximal end of a device, the distal end portion of the back end piece being snugly received within the oval shaped lumen of the unitary holder, and the proximal end portion of the back end piece being adapted to be connected to a suction tube; the unitary holder being elastically stretched when the parts are assembled to cause the device to be retained between the conically shaped portion and the retaining element, smoke to be evacuated passing through the elongated tubular opening, the oval shaped lumen, and the tubular back end piece to a suction tube.
