Abstract

A surgical retractor frame that is easily reconfigurable and self-maintaining in a desired position. The surgical retractor frame is formed from first and second rigid frame portions that are easily adjusted to various desired configurations. The first and second portions cooperate to define a support adapted to surround a surgical field and operable to releasably receive a plurality of surgical stays for temporary retraction of tissue during a surgical procedure. A malleable connector secures the first frame portion to the second frame portion, and permits the frame portions to be moved relative to one another to permit adjustment and proper positioning of the frame relative to the surgical field. The connector is a preferably a plastic coated wire that is adhesively affixed to the first and second frame portions.

Claims

1. A retractor frame formed from a substantially rigid material, said frame comprising a first frame portion and a second frame portion which cooperate to define a support adapted to surround a surgical field and to releasably receive a plurality of surgical stays for temporary retraction of tissue during a surgical procedure, the improvement comprising:

means for permanently securing the first frame portion to the second frame portion, said securing means being deformable to permit the first and second portions to be moved relative to one another.

2. A retractor frame according to claim 1, wherein said securing means comprises a connector that extends between said first and second frame portions, said connector being permanently attached to each of said first and second portions.

3. A retractor frame according to claim 1, wherein said securing means comprises a pair of connectors, each of said pair of connectors extending between said first and second frame portions and being permanently attached to each of said first and second frame portions.

4. A retractor frame according to claim 1, wherein deformation of said securing means is reversible.

5. A retractor frame according to claim 2, wherein said first and second frame portions are made from a molded material and said connector is made from a malleable material, said securing means having a first end affixed to said first frame portion and a second end affixed to said second frame portion.

6. A retractor frame according to claim 3, wherein said first and second frame portions are made from a molded material and said pair of connectors are made from a malleable material, each of said pair of connectors having a first end affixed to said first frame portion and a second end affixed to said second frame portion.

7. A retractor frame according to claim 4, wherein said securing means comprises a connector that extends between said first and second frame portions, said connector being permanently attached to each of said first and second frame portions.

8. A retractor frame according to claim 4, wherein said securing means comprises a pair of connectors, each of said pair of connectors extending between said first and second frame portions and being permanently attached to each of said first and second frame portions.

9. A retractor frame according to claim 7, wherein said first and second frame portions are made from a molded material and said connector is formed made a malleable material, said connector having a first end affixed to said first frame portion and a second end affixed to said second frame portion.

10. A retractor frame according to claim 8, wherein said first and second frame portions are made from a molded material and said pair of connectors are made from a malleable material, each of pair of connectors having a first end affixed to said first frame portion and a second end affixed to said second frame portion.

11. A retractor frame according to claim 9, wherein said connector comprises at least one wire.

12. A retractor frame according to claim 11, wherein said at least one wire is adhesively attached to said first and second frame portions.

13. A retractor frame according to claim 12, wherein said at least one wire is surrounded by a plastic sheath.

14. A retractor frame according to claim 10, wherein each of said pair of connectors comprise at least one wire.

15. A retractor frame according to claim 14, wherein said at least one wire is adhesively attached to said first and second frame portions.

16. A retractor frame according to claim 15, wherein said at least one wire is surrounded by a plastic sheath.
