Organic light emitting diode illuminated surgical retractor
A retractor having a housing having a handle portion at a first end and a blade portion at a second, opposite end. The retractor includes a light system having an organic light source for illuminating the blade portion. The light system is positioned within the housing such that it is fully encased by said housing. A pair of polarized light panels are attached to the blade portion for varying direction of light from the blade portion.
1. A retractor comprising:
a housing defining a blade portion and comprising:
a light system fully encased therein;
the light system comprising:
an organic light-emitting source to illuminate the blade portion;
a pair of longitudinally spaced-apart polarized light panels flanking the organic light-emitting source to pass polarized light from the light-emitting source to locations external to the blade portion, the spaced-apart polarized light panels to vary direction of the polarized light from the blade portion;
a separately-formed handle portion to accommodate a battery and one or more finger controls; and
a locking coupler, disposed between the housing and the separately-formed handle portion, to disengageably mechanically couple the handle portion to the housing and to electrically couple and decouple the one or more finger controls from the light system.
2. The retractor of claim 1 , wherein the organic light source is an organic light emitting diode.
3. The retractor of claim 1 , wherein the pair of polarized light panels are substantially rectangular-shaped.
4. The retractor of claim 1 , wherein the separately-formed handle portion is configured to permit removal of the battery.
5. The retractor of claim 1 , wherein the one or more finger controls are to vary intensity of light from the organic light-emitting source.
6. The retractor of claim 1 , wherein the one or more finger controls are to vary opaqueness or translucence of polarized light panels.
7. The retractor of claim 1 , wherein the organic light source and the pair of polarized light panels are configured to produce illumination of both sides of the blade portion or only a single side of the blade portion.
8. A retractor comprising:
a housing defining a blade portion and comprising:
a light system fully encased therein;
the light system comprising:
an organic light-emitting source to illuminate the blade portion;
a pair of longitudinally spaced-apart polarized light panels flanking the organic light-emitting source to pass polarized light from the light-emitting source to locations external to the blade portion, the spaced-apart polarized light panels to vary direction of the polarized light from the blade portion, wherein the organic light emitting diode unit extends along substantially an entire length of the pair of longitudinally spaced-apart polarized light panels such that light is emitted along an entire length of the organic light emitting diode unit;
a separately-formed handle portion to accommodate a battery and one or more finger controls; and
a locking coupler, disposed between the housing and the separately-formed handle portion, to disengageably mechanically couple the handle portion to the housing and to electrically couple and decouple the one or more finger controls from the light system.
9. The retractor of claim 8 , wherein the one or more finger controls is to control the power supplied to the organic light emitting diode unit.
10. The retractor of claim 9 , wherein the one or more finger controls is to control power supplied to the pair of polarized light panels.
11. The retractor of claim 8 , wherein the blade portion is configured to be disposable.
12. The retractor of claim 8 , wherein the
housing includes a first electric element connecting the battery to the organic light-emitting source.
13. A retractor comprising:
a housing defining a blade portion and comprising:
a light system fully encased therein;
the light system comprising:
an organic light-emitting source to illuminate the blade portion;
a pair of longitudinally spaced-apart polarized light panels flanking the organic light-emitting source to pass polarized light from the light-emitting source to a surgical field external to the blade portion, the spaced-apart polarized light panels to vary direction of the polarized light from the blade portion;
a separately-formed handle portion to accommodate a battery and one or more finger controls disposed between the battery the one or more finger controls to control intensity and direction of the polarized light from the organic light-emitting source; and
a locking coupler, disposed between the housing and the separately-formed handle portion, to disengageably mechanically couple the handle portion to the housing and to electrically couple and decouple the one or more finger controls from the light system.
14. The retractor of claim 13 , wherein the organic light source one or more organic light-emitting diodes.
15. The retractor of claim 13 , wherein the pair of voltage-controlled polarized light panels are substantially rectangular-shaped.
16. The retractor of claim 13 , wherein the separately-formed handle portion is configured to permit removal of the battery.
17. The retractor of claim 13 , wherein the one or more finger controls comprises a dimming switch to vary the intensity of the organic light source.
18. The retractor of claim 13 , wherein the spaced-apart polarized light panels are configured to produce multiple light configurations.
