Abstract

Various devices and methods are provided with respect to inserting multiple surgical instruments through a single surgical access device. A medical device including a flexible tissue retractor and a releasable insert having multiple instrument openings is disclosed. The insert can be in the form of an insert assembly including multiple components. A method of using the insert is also described, and includes releasably positioning an insert having multiple instrument openings into the tissue retractor

Claims

1. A method of accessing a body cavity through an incision, the method comprising:

positioning a tissue retractor in the incision;

releasably positioning an insert having multiple instrument openings into the tissue retractor.

2. The method of claim 1 wherein the step of positioning the insert comprises pressing the insert into the tissue refractor.

3. The method of claim 1 wherein the step of positioning the insert comprises deforming at least a portion of the tissue refractor.

4. The method of claim 1 wherein the step of positioning the insert comprises stretching at least a portion of the tissue refractor.

5. The method of claim 1 comprising positioning the insert in the tissue retractor to provide a passageway through the tissue retractor having a predetermined size and shape.

6. The method of claim 1 further comprising inserting at least one instrument through the insert and into the body cavity.

7. The method of claim 1 further comprising the step of removing the insert from the tissue retractor without removing the tissue retractor from the incision.

8. The method of claim 1 wherein the step of positioning the insert comprises positioning at least one instrument opening distally of a proximal end of the tissue retractor.

9. The method of claim 1 wherein the step of positioning the insert comprises positioning at least one instrument exit distally of a proximal end of the tissue retractor.

10. The method of claim 1 wherein the step of positioning the insert comprises positioning at least one instrument exit distally of a distal end of the tissue retractor.

11. The method of claim 1 wherein the step of positioning the insert comprises positioning at least one seal associated with an instrument passageway distally of a proximal end of the tissue retractor.

12. The method of claim 1 wherein the step of positioning the insert comprises positioning at least one seal associated with an instrument passageway distally of a distal end of the tissue retractor.

13. The method of claim 1 wherein the step of positioning the tissue refractor in the incision is performed before the step of positioning the insert in the tissue retractor.

14. A method of accessing a body cavity, the method comprising:

forming an incision;

positioning a tissue retractor in the incision;

positioning a sleeve to extend at least partially within the tissue retractor; and

positioning an insert having at least one instrument opening into the sleeve.

15. The method of claim 14 wherein the step of positioning the tissue retractor in the incision is performed before the step of inserting the sleeve into the refractor.

16. The method of claim 14 wherein the step of positioning the insert comprises positioning at least one instrument exit distally of a proximal end of the tissue retractor.
