Abstract

An electromechanical surgical assembly includes a surgical device, an adapter, and a filter. The surgical device includes a connecting portion having a distal facing recess including an electrical plug. The adapter includes a proximal facing cap configured to mate with the recess of the surgical device, the proximal facing cap including an electronic assembly including a plurality of electrical contact pins configured for electrical connection with the electrical plug. The filter is removably positioned within the recess of the surgical device. The plurality of electrical contact pins extend through the filter when the adapter is connected to the surgical device.

Claims

1. An electromechanical surgical assembly comprising:

a surgical device including a connecting portion having a distal facing recess including an electrical plug;

an adapter including a proximal facing cap configured to mate with the recess of the surgical device, the proximal facing cap including an electronic assembly including a plurality of electrical contact pins configured for electrical connection with the electrical plug; and

a filter removably positioned within the recess of the surgical device, wherein the plurality of electrical contact pins extend through the filter when the adapter is connected to the surgical device.

2. The electromechanical surgical assembly of claim 1, wherein the filter includes at least one layer of material selected from the group consisting of fabrics, foams, elastomers, thermoplastics, gels, and combinations thereof.

3. The electromechanical surgical assembly of claim 2, wherein the filter is composite of two or more layers of material.

4. The electromechanical surgical assembly of claim 1, wherein the filter includes a therapeutic agent.

5. The electromechanical surgical assembly of claim 4, wherein the therapeutic agent is selected from the group consisting of antimicrobials, antibacterials, antiseptics, astringents, disinfectants, and combinations thereof.

6. The electromechanical surgical assembly of claim 1, wherein the filter has a shape complementary to a shape of the recess.

7. The electromechanical surgical assembly of claim 1, wherein the filter includes slits.

8. The electromechanical surgical assembly of claim 1, wherein the filter is self-supporting.

9. The electromechanical surgical assembly of claim 1, wherein the filter is attached to a base plate mounted within the recess.

10. An electromechanical surgical device interconnectable with an adapter for selectively interconnecting a surgical loading unit with the surgical device, the surgical device comprising:

a handle housing;

a connecting portion extending distally from the handle housing, the connecting portion including at least one rotatable drive shaft and an electrical plug defined within a distal facing recess; and

a filter disposed within the recess distal to the at least one rotatable drive shaft and the electric plug, the filter configured to prevent contaminants from communicating with the electrical plug.

11. The electromechanical surgical device of claim 10, wherein the filter includes at least one layer of material selected from the group consisting of fabrics, foams, elastomers, thermoplastics, gels, and combinations thereof.

12. The electromechanical surgical device of claim 11, wherein the filter is composite of two or more layers of material.

13. The electromechanical surgical device of claim 10, wherein the filter includes a therapeutic agent.

14. The electromechanical surgical device of claim 13, wherein the therapeutic agent is selected from the group consisting of antimicrobials, antibacterials, antiseptics, astringents, disinfectants, and combinations thereof.

15. The electromechanical surgical device of claim 10, wherein the filter has a shape complementary to a shape of the recess.

16. The electromechanical surgical device of claim 10, wherein the filter includes slits.

17. The electromechanical surgical device of claim 10, wherein the filter is self-supporting.

18. The electromechanical surgical device of claim 10, wherein the filter is attached to a base plate mounted within the recess.

19. A method of using an electromechanical surgical assembly, the method comprising:

positioning a filter within a distal facing recess of a connecting portion of a surgical device, the distal facing recess including an electrical plug; and

connecting an adapter to the surgical device, the adapter including a proximal facing cap configured to mate with the distal facing recess, the proximal facing cap including an electronic assembly including a plurality of electrical contact pins configured to extend through the filter for electrical connection with the electrical plug.

20. The method of claim 19, further comprising the step of moistening the filter with a therapeutic agent prior to positioning the filter within the distal facing recess of the connecting portion of the surgical device.

21. The method of claim 19, further comprising the steps of:

disconnecting the adapter from the surgical device; and

removing the filter from the recess of the surgical device.

22. The method of claim 21, further comprising the steps of:

positioning a new filter within the distal facing recess of the surgical device; and

attaching the adapter or a different adapter to the surgical device.

23. The method of claim 19, wherein the step of positioning the filter within the distal facing recess of the connecting portion of the surgical device includes attaching the filter to a base plate mounted within the recess.
