摘要： A hand access device includes a housing defining a longitudinal axis and having a passageway therethrough dimensioned to permit passage of a surgeon's arm and a fabric seal mounted within the opening and being dimensioned to form a substantial sealing relation with the surgeon's arm. The fabric seal is elongated extending along the longitudinal axis and may define a general hour glass configuration. A pair of flexible bands may be mounted about the fabric seal. The flexible bands are adapted to engage an outer surface of the seal to bias the fabric seal to a closed position thereof.

摘要： A surgical access apparatus includes a liner base and an access housing for positioning outside the body. The liner base includes an inner member adapted for insertion through an opening within body tissue for positioning within the body; a sleeve member connected to the inner member and dimensioned to extend from the inner member through the opening within the body tissue, and a plurality of tensioning elements connected to the inner member and associated with the sleeve member to impart a tensioning effect on the sleeve member. The access housing includes a first element and a second element. The second element is operatively connected to the tensioning elements and adapted for rotational movement relative to the first member to cause the tensioning elements to displace the inner member toward the access housing and to cause the sleeve member to engage and retract tissue defining the opening within the body.

摘要： A surgical stapling instrument including a handle assembly, an elongated body portion extending distally from the handle assembly, and a head portion. The handle assembly includes a firing trigger and a firing indicator. The firing trigger is movable between a first non-actuated position and a second actuated position. The head portion is disposed adjacent a distal portion of the elongated body portion and includes an anvil assembly and a shell assembly. The anvil assembly is movable in relation to the shell assembly between spaced and approximated positions. Engagement structure of the firing trigger moves the firing indicator from a first position to a second position when the firing trigger is moved from its first non-actuated position toward its second actuated position.

摘要： A surgical stapling device few sequentially applying a plurality of fasteners to body tissue and simultaneously incising tissue is provided. The device is adapted to receive disposable loading units having staples in linear rows whose surgical stapling length can be Between about 30 mm and 60 mm. The disposable loading unit includes a proximal body portion, a mounting assembly and a tool assembly. The mounting assembly is secured to the proximal end of the tool assembly and pivotally mounted about a pivot axis to the distal end of the proximal body portion. A support member or blow-out plate assembly is positioned on opposite sides of the pivot axis and extends between the proximal body portion and the mounting assembly.
