Abstract

A novel surgical retractor is provided including a handle assembly, a housing and a collapsible retractor assembly connected to a distal end of the housing. The handle assembly includes a stationary handle in cooperation with an actuating structure for manipulating the collapsible retractor assembly through the housing.
The handle assembly may be configured in a variety of forms including palm grips, pistol grips, axial grips, ring grips, etc. The housing includes a tubular structure having an inner tube axially disposed within an outer tube.
The outer tube is fixed in the stationary handle with the inner tube passing through the outer tube and connected to the actuating structure. Where desired, either the outer or inner tube may be rotatably attached to the stationary handle.
The retractor assembly is attached to the distal end of the housing and includes a reciprocal yoke assembly interconnected with a plurality of collapsible interleaved retractor blades. One element of the yoke assembly is typically maintained stationary while the other is allowed to reciprocate axially to deploy the interleaved retractor blades into a fan configuration.
