Abstract
A surgical retractor comprising a blade having first and second opposing surfaces, and a handle extending from a proximal end of the blade, wherein the first surface of the blade includes a non-slip texture having a preferential grip in a first direction corresponding to direction of extraction of the surgical retractor from an incision and having a minimal or no grip in a second direction opposite to the first direction and in a third direction transverse to the first and second directions.
Claims30
A surgical retractor comprising:
- a blade;
- a handle extending from the blade;
- a cover attached to the blade, the cover defining a plurality of light openings;
- and
- a plurality of direct light sources positioned adjacent a surface of the blade, each of the plurality of direct light sources being aligned with a corresponding one of the plurality of light openings and arranged at an angle relative to the surface of the blade, wherein the angle of the plurality of direct light sources relative to the surface of the blade and the alignment of each of the plurality of direct light sources with the corresponding one of the plurality of light openings causes light emitted by the plurality of direct light sources to travel toward a distal end portion of the blade when the plurality of direct light sources are activated.

A surgical retractor comprising:
- a blade;
- a handle extending from the blade, the handle comprising an end portion that is angled relative to a grip portion of the handle such that the end portion of the handle is offset from a longitudinal axis of the grip portion of the handle;
- a cover attached to the blade, the cover defining a plurality of openings;
- a plurality of direct light sources positioned adjacent a surface of the blade and arranged at an angle relative to the surface of the blade, each of the plurality of direct light sources being aligned with a corresponding one of the plurality of openings in the cover, wherein the angle of the plurality of direct light sources relative to the surface of the blade and the alignment of each of the plurality of direct light sources with the corresponding one of the plurality of openings causes light emitted by the plurality of direct light sources to travel toward a distal end portion of the blade when the plurality of direct light sources are activated;
- a switch positioned on the handle, the switch being configured to be operated by a user when the user is grasping the grip portion of the handle, and the switch being configured to activate the plurality of direct light sources when the switch is operated by the user;
- and
- a smoke evacuation channel extending between the surface of the blade and the cover, the smoke evacuation channel being laterally spaced from each of the plurality of direct light sources.
