ABSTRACT:
A gas-sealed instrument for use in laparoscopic procedures in a gas-insufflated body cavity. The instrument comprises a static portion, a moving portion, and a sealing means for preventing gas from escaping from the body cavity through the static portion. The static portion includes a handle, and an elongate outer tube having a bore, a proximal portion attached to the handle, and a distal portion adapted for inserting into the body cavity. The moving portion includes an operating lever pivotally mounted in the handle, and an elongate operating rod mounted in the bore of the elongate outer tube, and sliding axially relative thereto in response to the operating lever.
The sealing means includes a cylinder in the handle and a piston slidably mounted in the cylinder. The cylinder is in gas-tight communication with the bore of the outer tube, and the piston interconnects the operating lever and the operating rod.
