Abstract

A surgical stay apparatus provides a frame that can be annular and conforming to a patient'"'"'s body at a surgical site. An opening allows a surgeon to access the surgical site through the central portion of the frame. A stay includes a handle body having proximal and distal ends. The first bore extends through the handle body communicating at least with the proximal end of the handle body. The second bore extends at least a partial distance through the handle body and communicates with the proximal surface of the body. An elastic member extends through the first bore, the elastic member having an elongated portion that extends from the distal end of the handle body and a short proximal end that is positioned at the handle body occupying at least a portion of the first bore. A hook member having proximal and distal end portions occupies the second bore of the handle body, the hook member has a curved hook at the distal end portion of the handle body for retracting body tissue. The handle body can be of an injection molded plastic construction. The elastic member can be an elongated section of hollow silicone tubing. The hook can be shaped to snap into one of the bore of the handle body for anchoring the hook to the handle body. In one embodiment, a plastic injection molded stay handle can have a "V" slot to retain the distal end of the elastic tubing.

Claims

1. A surgical retractor stay apparatus comprising:

a) frame that conforms to a patient'"'"'s body at a surgical site;

b) a stay connectable to the frame that includes a handle body having proximal and distal ends;

c) a first bore with a central longitudinal axis that extends through the handle body, communicating with at least the proximal end of the handle body;

d) a second bore that extends at least a partial distance through the handle body and communicating with the proximal end of the body;

e) an elastic member that extends through the first bore, the elastic member having an elongated portion that extends from the distal end of the handle body and a short proximal end that is positioned at the handle body occupying at least a portion of the first bore;

f) a hook member having proximal and distal end portions, the proximal end portion occupying the second bore of the handle body; and

g) the hook member having a curved hook at the distal end portion of the handle body.

2. The surgical retractor stay of claim 1, wherein the first bore has a linear central longitudinal axis.

3. The surgical retractor stay of claim 1, wherein the first bore has a central longitudinal axis that includes two sections that offset with respect to one another.

4. The surgical retractor stay of claim 1, wherein the first bore includes two sections that are generally parallel to one another.

5. The surgical retractor stay of claim 1, wherein the first bore has a smaller diameter section and a larger section that is larger in diameter than the smaller diameter section.

6. The surgical retractor stay of claim 1 further comprising a locking member that forms a connection with the first bore and a portion of the elastic member, said locking member locking the elastic member to the handle body at the first bore.

7. The surgical retractor stay of claim 1 further comprising a locking plug inserted into the handle body at an open end portion of the first bore for anchoring the elastic member to the handle body.

8. The surgical retractor stay of claim 1, wherein the first bore has a proximal end portion that communicates with the proximal end of the handle body and a distal end portion.

9. The surgical retractor stay of claim 8 further comprising a locking plug inserted into the handle body at the distal end portion of the first bore.

10. The surgical retractor stay of claim 8 further comprising a tapered locking plug inserted into the handle body at the distal end of the first bore, the elastic member being hollow and the plug having a pointed end that is shaped to fit into and expand the distal end of the elastic member.

11. The surgical retractor stay of claim 8, wherein the first bore has a distal tapered section and further comprising a locking plug that can be inserted into the handle body at the tapered section of the first bore, wherein the first bore has a maximum diameter at the distal end of the hand body.

12. The surgical retractor stay of claim 1, wherein the elastic member is hollow along at least a portion of its length.

13. The surgical retractor stay of claim 12 further comprising a locking plug inserted into the handle body at an open end portion of the first bore for anchoring the elastic member to the handle body.

14. The surgical retractor stay of claim 13, wherein the plug occupies a portion of the elastic member bore.

15. The surgical retractor stay of claim 12, wherein the first bore has a proximal end portion that communicates with the proximal end of the handle body and a distal end portion.

16. The surgical retractor stay of claim 15 further comprising a locking plug inserted into the handle body at the distal end portion of the first bore.

17. The surgical retractor stay of claim 1, wherein the second bore comprises multiple bore sections having axes that are generally parallel.

18. The surgical retractor stay of claim 1, wherein the second bore comprises multiple bore sections having axes that are angularly oriented relative to one another.

19. The surgical retractor stay of claim 1, wherein the hook member curved hook portion extends away from the handle body, positioned to grip selected patient tissue and further comprising a hook anchor and a shoulder on the handle body that receives the hook anchor for transferring load between the hook member and handle body.
