Abstract: A retractor for use in surgical operations can include a first blade assembly comprising a first blade, a first actuator configured to translate the first blade along a first translation direction, a first lock handle configured to limit translation along a direction opposite the first translation direction. The retractor can include a second blade assembly comprising a second blade. The method can include providing a retractor comprising a first blade assembly comprising a first blade, a first actuator, a first lock handle, and second blade assembly comprising a second blade. The method can include translating the first blade along a first translation direction with the first actuator. The first lock handle can limit translation along a direction opposite the first translation direction.

Abstract: Nicheless lighting assemblies principally for swimming pools and spa are detailed. The lighting assemblies include features configured to dissipate heat. The assemblies additionally are designed to reduce possibility of water intrusion. Some versions of the assemblies may include thermally-conductive plastic overmolded onto at least one of a lens or a heat spreader. Versions of the assemblies additionally or alternatively may include a generally annular heat sink to which a printed circuit board containing at least one light-emitting diode (LED) is attached. Versions of the assemblies may be divided into subassemblies, one subassembly fitting into another, or include protective covers.
