Abstract

Various methods and devices are provided for allowing multiple surgical instruments to be inserted into sealing elements of a single surgical access device. The sealing elements can be movable along predefined pathways within the device to allow surgical instruments inserted through the sealing elements to be moved laterally, rotationally, angularly, and vertically relative to a central longitudinal axis of the device for ease of manipulation within a patient's body while maintaining insufflation.

Claims20

Dependent claims

A surgical device, comprising:

a housing defining a working channel configured to provide access to a surgical site, the housing including
a base member having formed therein a first hole defining a first hole area and a second hole defining a second hole area, and
a flexible member having formed therein a first opening defining a first opening area, and a second opening defining a second opening area, the first opening being aligned with the first hole and the first opening area being less than the first hole area, and the second opening being aligned with the second hole and the second opening area being less than the second hole area, and the flexible member being configured to provide a fluid seal of the working channel;
a first sealing element seated in the first opening in a sealed relationship with the flexible member, the first sealing element being configured to provide a fluid seal around a first instrument inserted therethrough;
and
a second sealing element seated in the second opening in a sealed relationship with the flexible member, the second sealing element being configured to provide a fluid seal around a second instrument inserted therethrough;
wherein the first sealing element is movable within the first hole relative to both the base member and the second sealing element, movement of the first sealing element being configured to cause deformation of the flexible member while maintaining the sealed relationship with the flexible member;
and
wherein the second sealing element is movable within the second hole relative to both the base member and the first sealing element, movement of the second sealing element being configured to cause deformation of the flexible member while maintaining the sealed relationship with the flexible member.

6 more elements

A surgical device, comprising:

a retractor having an inner lumen extending therethrough, the retractor being configured to be positioned within tissue to provide a pathway therethrough;
a housing coupled to the retractor, the housing including a base member and a deformable seal member, the base member having a plurality of predefined tracks formed therein, and a surface of the deformable seal member defining a horizontal plane;
and
a plurality of sealing elements each seated in the deformable seal member and each being configured to form a seal around an instrument inserted therethrough and into the inner lumen of the retractor, wherein:
each one of the sealing elements is movable within one of the predefined tracks,
each one of the sealing elements is movable horizontally along the horizontal plane within its associated one of the predefined tracks independent of the others of the sealing elements and relative to the base member, the horizontal movement causing deformation of the deformable seal member, and
each one of the sealing elements is configured to move vertically out of the horizontal plane independent of the others of the sealing elements and relative to the base member, the vertical movement causing deformation of the deformable seal member.
