ABSTRACT:
A surgical port and dilator are useful for creating access to surgical sites having tortuous geometries and/or requiring relatively long and narrow access to the surgical site. The surgical port or dilator can be provided with an oblique distal end to facilitate placement and the displace tissue near angled surfaces. The surgical port can be inserted into the operative site following dilation in the same fashion as a conventional port. Once inserted, however, the surgical port may then be elongated to provide relatively long and narrow, elliptically- shaped access to the surgical site. The elongation of the port allows the surgeon access to long and narrow surgical sites, such as the spine, without having to expand radially. This reduces trauma to the patient. A locking means is also provided to hold the surgical port in the open position until a release mechanism is activated.
