Abstract
An illuminated surgical retractor embodiment includes a blade, a handle, a curved section and an illumination assembly. The blade has a top surface and a bottom surface. The handle extends at an angle from a proximal end of the blade. The curved section connects the handle to the blade. The illumination assembly includes at least one light source, at least one battery and an activation device for energizing the light source. In an embodiment, the blade, handle, and curved section are molded from a glass-fiber reinforced polymer.
Claims26
An illuminated surgical retractor, comprising:
- a blade having a top surface and a bottom surface;
- a handle extending at an angle from a proximal end of the blade;
- a curved section connecting the handle to the blade;
- and
- an illumination assembly comprising at least one light source, at least one battery and an activation device comprising one of a switch and a removable dielectric tab for energizing the light source, and the illumination assembly being non-releasably attached to the retractor;
- wherein the blade, handle, and curved section are molded from a glass-fiber reinforced polymer having a flexural strength of at least 300 Mpa;
- and
- wherein the blade, being molded from the glass-fiber reinforced polymer, deforms less than 10 mm under 15 lbs of force applied thereto.
An illuminated surgical retractor, comprising:
- a blade having a top surface and a bottom surface;
