Abstract

A surgical apparatus includes a seal anchor member. The seal anchor member includes a first end, a second end, at least one longitudinal port extending between the two ends, and a seal assembly disposed within the at least one longitudinal port. The seal assembly can be positioned at any location along the length of the at least one longitudinal port. The seal assembly comprises a seal housing which is dimensioned to receive a surgical instrument inserted into the at least one longitudinal port and form a substantially fluid-tight seal therewith. The seal housing may comprise a pivotable member to pivot the surgical instrument inserted therein. The at least one longitudinal port may define two gradually enlarging openings to facilitate the maneuverability of the surgical instrument inserted therein. The at least one longitudinal port may comprise a protective sleeve to protect it from accidental penetration by the surgical instrument.

Claims

1. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:

a seal anchor member comprising a first end, a second end, and at least two longitudinal ports extending between the first and second ends, each longitudinal port of the at least two longitudinal ports defining a proximal end and a distal end; and

at least two seal assemblies configured for substantially sealed reception of an object therein, a first seal assembly of the at least two seal assemblies disposed within a first longitudinal port of the at least two longitudinal ports and positioned at a first distance from the proximal end of the first longitudinal port, and a second seal assembly of the at least two seal assemblies disposed within a second longitudinal port of the at least two longitudinal ports and positioned at a second distance from the proximal end of the second longitudinal port, the first distance being different than the second distance, wherein the first and second seal assemblies are selectively movable from the proximal to the distal ends of the respective first and second longitudinal ports.

2. The surgical apparatus according to claim 1, wherein each seal assembly of the at least two seal assemblies comprises a seal housing for receiving the object and forming a substantially fluid-tight seal therewith.

3. The surgical apparatus according to claim 1, wherein each seal assembly of the at least two seal assemblies comprises a closure valve configured to inhibit communicating insufflation gas therethrough.

4. The surgical apparatus according to claim 1, wherein each seal assembly of the first seal assembly and the second seal assembly defines a radial diameter larger than a respective radial diameter of the first longitudinal port and the second longitudinal port.

5. The surgical apparatus according to claim 1, wherein at least one longitudinal port of the at least two longitudinal ports includes a seal receiving cavity configured to receive one seal assembly of the at least two seal assemblies therein, the seal receiving cavity oriented transverse to a longitudinal axis of the at least one longitudinal port.

6. The surgical apparatus according to claim 1, wherein the first and second longitudinal ports define first and second longitudinal axes, respectively, the first and second longitudinal axes being non-collinear.
