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.
Core Innovation
The invention describes a surgical retractor comprising a handle and a blade extending at an angle relative to one another. Multiple direct light sources are positioned on or adjacent to the blade surface at a non-zero angle relative to it. A cover secured to the blade defines openings aligned with respective light sources, permitting emitted light to travel toward the distal end portion of the blade.
A further configuration incorporates an illumination assembly with a smoke evacuation assembly configured for coupling to a vacuum source and a controller for operating the illumination assembly. The handle extends at an angle from the blade, wherein the distal end of the handle extends into a curved section offset from the central plane of the handle.
Claims Coverage
The two independent claims cover three main inventive features across the claimed surgical retractor configurations.
Angled blade-mounted light sources and aligned cover openings
Claims 1 and 16 recite multiple direct light sources positioned on or adjacent to a blade surface at a non-zero angle, with each light source aligned with an opening defined in a cover secured to the blade to direct emitted light toward the distal end portion of the blade.
Smoke evacuation assembly and illumination controller
Claim 16 recites a smoke evacuation assembly configured to be coupled to a vacuum source and a controller for controlling operation of the illumination assembly.
Offset curved handle section
Claim 16 recites a handle extending at an angle from the blade, with the distal end of the handle extending into a curved section offset from a central plane of the handle.
The independent claims cover blade-mounted angled illumination with aligned cover openings, vacuum-coupled smoke evacuation, illumination control, and an offset curved handle section.
Stated Advantages
The angled light sources and aligned cover openings direct emitted light toward the distal end portion of the blade.
The smoke evacuation tubes convey smoke, fluids, and debris away from an operating site.
Documented Applications
A surgical retractor providing illumination directed toward the distal end portion of a blade and evacuating smoke, fluids, and debris away from an operating site via smoke evacuation tubes.
