Abstract
An access port or retractor tube provides access through tissue to a surgical site or field, such as at the brain or spine, in a minimally invasive manner. The access port permits a user to clearly view and access the surgical field, including areas medial thereto, in a minimally invasive manner by dilating of separating tissue rather than cutting tissue. Neuro monitoring and neuro navigation are tools essential to neuro surgery to protect vital and eloquent tissues. Combining navigation and monitoring into the access ports/reactor tubes would enable the surgeon to be more precise and efficient during minimally invasive procedures while still being maximally effective in protecting non operative tissues.
Claims20
A retractor tube comprising:
- a distal end configured to incorporate any of a gasket, a boot or an expandable sleeve;
- and
- a base plate, at a proximal end of the retractor tube, configured to secure the retractor tube to any of an operating room table, a patient fixation device and a boney structure of a patient.
A cylindrical sleeve configured to cover and expand with an outer side of an expandable iris cylinder of a retractor tube.
A locator rod comprising:
- a proximal end configured to incorporate neuro navigation and neuro monitoring sensors.
A series of dilating tubes respectively comprising:
- a distal end configured to accommodate expansion of any of a gasket or boot.
A gasket, wherein
- the gasket is configured to attach to at least any distal end of a retractor, a dilating tube and a locator rod.
A method of retracting human tissue during brain or spinal surgery, the method comprising:
- inserting a locator rod with neuro monitoring and neuro navigation capabilities to identify a desired surgical site.
