Illuminated retractor for use in connection with harvesting a blood vessel from the arm
View Patent ↗An illuminated surgical retractor for defining and illuminating a subcutaneous surgical field in the space near a vessel (such as the radial artery or the basilic vein) during a procedure for harvesting the vessel, wherein the illuminated surgical retractor includes a handle member pivotally connected at an acute angle to a first elongate section that has a non-liner shape, and includes a second elongate section releasably connected to the first elongate section, wherein a portion of the second elongate section defines an illumination input end portion, which is optically coupled to a light source to substantially illuminate the second elongate section, and further including an insertion area positioned on the proximal end portion of the first elongate section to allow the second elongate section to be inserted into the first elongate section.
1. An illuminated surgical retractor comprising:
a handle member having a first handle member end portion and a second handle member end portion;
a first elongate section having a first elongate proximal end portion, a first elongate distal end portion, and a first elongate inner surface extending from the first elongate proximal end portion to near the first elongate distal end portion and having a substantially bent shape therebetween, the second handle member end portion of said handle member connected to the first elongate distal end portion of said first elongate section such that said handle member is pivotal with respect thereto and forms an acute angle with said first elongate section;
a second elongate section having a second elongate proximal end portion, a second elongate distal end portion, and a second elongate outer surface extending from the second elongate proximal end portion to near the second elongate distal end portion, and a second elongate inner surface extending from the second elongate proximal end portion to near the second elongate distal end portion, the second elongate distal end portion of said second elongate section defining an illumination output member;
wherein the vertex of the bending angle forming the substantially bent shape commences at approximately the midpoint between the first elongate distal end portion and the first elongate proximal end portion.
2. The illuminated surgical retractor of claim 1 , wherein the first elongate inner surface is bent at an angle in the range of about 80° to 175°.
3. The illuminated surgical retractor of claim 2 , wherein the first elongate inner surface is bent at an angle in the range of about 140° to 160°.
4. The illuminated surgical retractor of claim 1 , wherein the second elongate outer surface has a bent shape that substantially corresponds to the bent shape of the first elongate inner surface.
5. The illuminated surgical retractor of claim 4 , wherein the second elongate outer surface has a shape that is substantially identical to the bent shape of the first elongate section prior to connection thereof to the first elongate section, and that does not substantially change following connection thereof to the first elongate section.
6. An illuminated surgical retractor comprising:
a handle member having a first handle member end portion and a second handle member end portion;
a first elongate section having a first elongate proximal end portion and a first elongate distal end portion, with a first elongate inner surface extending between the first elongate proximal end portion and the first elongate distal end portion, the first elongate inner surface having a substantially bent shape therebetween, wherein said second handle member end portion of said handle member is connected to said first elongate section;
a second elongate section having a second elongate proximal end portion and a second elongate distal end portion with a second elongate outer surface extending between the second elongate proximal end portion and the second elongate distal end portion, a second elongate inner surface extending between the second elongate proximal end portion and the second elongate distal end portion, the second elongate distal end portion of said second elongate section defining an illumination input end portion;
a connector releasably coupling the illumination input end portion to an optical cable; and
a pivotal connector pivotally coupling the handle member to the first elongate section;
wherein the vertex of the bending angle forming the substantially bent shape commences at approximately the midpoint between the first elongate distal end portion and the first elongate proximal end portion.
7. The illuminated surgical retractor of claim 6 , wherein the first elongate inner surface is bent at an angle in the range of about 80° to 175°.
8. The illuminated surgical retractor of claim 7 , wherein the first elongate inner surface is bent at an angle in the range of about 140° to 160°.
9. The illuminated surgical retractor of claim 6 , wherein the second elongate outer surface has a bent shape that substantially corresponds to the bent shape of the first elongate inner surface.
10. The illuminated surgical retractor of claim 9 , wherein the second elongate outer surface has a shape that is substantially identical to the bent shape of the first elongate section prior to connection thereof to the first elongate section, and that does not substantially change following connection thereof to the first elongate section.
11. An illuminated surgical retractor comprising:
a handle member having a first handle member end portion and a second handle member end portion;
a first elongate section having a first elongate proximal end portion, a first elongate distal end portion, a first elongate inner surface extending from the first elongate proximal end portion to near the first elongate distal end portion, and a first elongate convex outer surface extending from the first elongate proximal end portion to near the first elongate distal end portion, the second handle member end portion of said handle member connected to the first elongate distal end portion of said first elongate section
such that said handle member is pivotal with respect thereto and forms an acute angle with said first elongate section;
a second elongate section having a second elongate proximal end portion, a second elongate distal end portion, and a second elongate outer surface extending from the second elongate proximal end portion to near the second elongate distal end portion, and a second elongate inner surface extending from the second elongate proximal end portion to near the second elongate distal end portion, the second elongate distal end portion of said second elongate section defining an illumination output member.
12. The illuminated surgical retractor of claim 11 , wherein at least a portion of the first elongate inner surface comprises a mirrored surface.
13. The illuminated surgical retractor of claim 11 , wherein at least a portion of the second elongate inner surface comprises a micro-lens surface.
14. The illuminated surgical retractor of claim 11 , wherein at least a portion of the second elongate inner surface comprises a graded dot screen surface.
15. The illuminated surgical retractor of claim 11 , wherein at least a portion of the second elongate inner surface comprises a reflective surface.
16. The illuminated surgical retractor of claim 11 , wherein the first elongate section comprises a metal or alloy.
17. The illuminated surgical retractor of claim 11 , wherein the second elongate section comprises a semi-rigid material.
18. The illuminated surgical retractor of claim 17 , wherein the second elongate section comprises an acryl resin.
