Abstract
A portable dual-blade retractor comprising a handle having a first end and a second end, a first blade extending from the first end of the handle, a second blade extending from the second end of the handle, and an illumination assembly including (a) one or more first direct light sources provided on the first blade and (b) one or more second direct light sources provided on the second blade, wherein the first and second direct light sources are individually controlled.
Core Innovation
The invention is a portable dual-blade retractor with a handle, a first blade, a second blade, and an illumination assembly. The assembly has a direct light source on each blade, electrically connected to a control circuit and individually controlled. The supplied description also identifies onboard battery power, a shared switch for blade-specific lighting control, angled lighting, and flexible circuits that dissipate heat.
The retractor also includes a smoke evacuation assembly configured to provide suction to the blades. The description identifies separate internal suction conduits, recessed outlet openings, and a removable adapter that couples an opening to a vacuum source without obstructing the user's field of view. The supplied partial content does not include the abstract, summary, or background sections, so the problem being solved is not explicitly described.
Claims Coverage
The supplied claim information identifies three independent claims, each covering a dual-blade retractor. The claims address individually controlled blade lighting, a smoke evacuation assembly with a nonprotruding adapter opening, and an adapter opening positioned at a handle-and-blade joint.
Individually controlled blade lighting
Claim 1 covers a portable dual-blade retractor with a handle and a blade extending from each end. An illumination assembly includes a control circuit and a direct light source positioned on each blade, with the light sources individually controlled. The retractor is configured to position an internal power source so that it overlaps with the control circuit.
Smoke evacuation through a nonprotruding adapter opening
Claim 18 covers a dual-blade retractor with a smoke evacuation assembly configured to provide suction to both blades. An opening in the outer housing accommodates a removable adapter that fluidly couples to a vacuum source and provides suction to at least one blade; the opening does not protrude from the outer-housing surface.
Smoke evacuation through an opening at a blade joint
Claim 25 covers a dual-blade retractor with a smoke evacuation assembly configured to provide suction to both blades. An opening in the outer housing accommodates a removable adapter for fluidly coupling to a vacuum source and providing suction to at least one blade, and the opening is located at a joint between the handle and one of the blades.
The three independent claims cover a dual-blade retractor with individually controlled lighting, and two smoke evacuation configurations distinguished by the placement and surface relationship of the adapter opening.
Stated Advantages
The flexible circuits dissipate heat.
The removable adapter connects to a vacuum source without obstructing the user's field of view.
