Surgical access assembly and method of using same

摘要

A surgical access assembly is described that includes an outer sheath and a selectively removable obturator. The outer sheath is defined by an open distal end and an open proximal end and includes a hollow body portion therebetween. The obturator is defined by a distal end and a proximal end, wherein the distal end further comprises a tapered distal tip member. The obturator is configured to be received within the outer sheath such that the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator is in an introducing configuration. The outer sheath further includes a gripping member, wherein the gripping member includes at least one retaining notch formed on an outer surface thereof.

1. A surgical access system, comprising
an outer sheath defined by an open distal end and an open proximal end and including a hollow body portion therebetween a central axis extending therethrough; an obturator defined by a distal end and a proximal end, wherein the distal end further comprises a tapered distal tip member; wherein the obturator is configured to be received within the outer sheath such that the tapered distal tip member protrudes from the open distal end of the outer sheath when the obturator is in an introducing configuration; and wherein the outer sheath further includes a gripping member attached to the open proximal end, wherein the gripping member has a proximal end face surface, an outer periphery, and an access opening formed through the proximal end face surface and wherein at least one retaining notch is formed on the proximal end face surface thereof such that the at least one retaining notch extends from the access opening to the outer periphery of the gripping ring and wherein at least one retaining opening is disposed through the proximal end face surface, wherein the at least one retaining opening is configured to cooperate with a fastening element to selectively secure the outer sheath within a patient.
