Illuminated and modular soft tissue retractor

摘要

A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

主权项

1. A surgical retractor, said retractor comprising: a handle having a proximal portion and a distal portion, and a vacuum line disposed alongside or within the handle; an elongate retractor blade coupled to the handle having a proximal portion and a distal portion; at least one smoke evacuation channel disposed along a length of the elongate retractor blade; and at least one vacuum regulating element adjacent the elongate retractor blade, wherein the at least one vacuum regulating element comprises at least one vane, wherein the at least one vane comprises a first vane and a second vane adjacent the elongate retractor blade, wherein the first vane and the second vane are slidably disposed over one another, wherein the first vane comprises a plurality of through holes, and wherein the second vane is slidably disposed over the first vane such that movement of the second vane relative to the first vane controls a number of through holes that are exposed.
