Abstract
Access devices including access ports and retractors, which enhance the working area and access to a surgical site. The access port includes a tubular body with at least one sidewall defining an interior path along the length of the tubular body. The sidewall includes a rigid portion and a flexible portion. The flexible portion is able to stretch or deform, for example, to accommodate an angled trajectory of a surgical implement. A surgical access device for retracting tissue includes a plurality of retractor blades. The outer surface of the retractor blades form a substantially circular cross-sectional configuration with a plurality of spiral ridges projecting therefrom such that advancement of the retractor into the surgical site may be improved.
Claims13
A tubular surgical access device for providing access to a patient during surgery comprising:
- a first end defining a first opening configured to receive a surgical implement;
- a second end defining a second opening configured to access the patient;
- a length extending from the first end to the second end;
- and a sidewall comprising a substantially non-elastic rigid portion extending annularly around the entire periphery of the second end and a flexible portion extending along a portion of the length of the tubular surgical access device and a portion of the periphery of the first end of the tubular surgical access device, wherein the sidewall defines an interior path along the length of the tubular surgical access device, wherein the flexible portion is resilient such that the flexible portion returns to or near its original shape after being expanded;
- and wherein the first end comprises both the rigid portion and the flexible portion.
