Abstract
A surgical retractor designed to retract large areas in abdominal cavity surgery. The retractor is comprised of a handle that may be used interchangeably with different sized retractor blades to suit a particular surgical purpose. The handle is disposed or can be adjusted to be disposed at an angle of generally 90.degree. with respect to the retractor blade to afford an easier and more comfortable hold and pull than that experienced with any other designed retractor. The retractor may be fitted with one large retractor blade where previously two or three small retractors were used, and is, therefore, useful in small hospitals in major surgery such as aneurysms, Whipples and node dissections.
