NAVIGATING INTRODUCER FOR TISSUE ACCESS SYSTEM

摘要

A surgical access system is disclosed that includes an outer sheath, an introducer, and a navigational stylet. 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. The distal end further comprises a tapered distal tip member that terminates in a distal tip. The navigational stylet is configured to be selectively fixed to the obturator and is configured to indicate the location of the obturator within a patient during use. 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.

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; an introducer defined by a distal end and a proximal end, wherein the distal end further comprises a tapered distal tip member that terminates in a distal tip, wherein the introducer further comprises a channel disposed through the introducer; and a navigational stylet selectively positioned within the channel of the introducer; wherein the navigational stylet is configured to indicate a location of the introducer within a patient during use; wherein the introducer 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 introducer is in an introducing configuration.
