Abstract

A floating connector adapted for use with microwave surgical instruments is presented. The disclosure provides for the use of cost-effective and readily available non-floating connectors in a floating housing which can compensate for dimensional variations and misalignments between the connectors. Multiple connectors of varying types can therefore be used within a single support housing without requiring the costly precision manufacturing processes normally associated with such multiple connector assemblies. The floating connector is suitable for use with electrical connections as well as fluidic connections.

Claims

1. A floating connector, comprising:

a floating member having a connector fixedly disposed therethrough, the connector including a mating end adapted to couple to a mating connector and a mounting end which mounts to the floating member;

a support member having an opening defined therein, the opening including an internal dimension greater than the mounting end of the connector to define a clearance between the opening and the mounting end of the connector, the floating member and the connector being positioned in substantial concentric alignment with the opening; and

an elastomeric coupling fixedly disposed between the floating member and the support member.

2. The floating connector according to claim 1, wherein the floating member includes a perimeter which extends beyond the edge of the opening and wherein the elastomeric coupling is fixedly disposed between the floating member and the support member along a perimetric interstice defined by the overlap therebetween.

3. The floating connector according to claim 1, wherein the floating member is concentrically disposed within the opening, the floating member and the opening defining an annular interstice therebetween, and wherein the elastomeric coupling is fixedly disposed between the floating member and the support member along the annular interstice.

4. The floating connector according to claim 1, wherein the elastomeric coupling is constructed from material selected from a group consisting of rubber, neoprene, nitrile, silicone, foam rubber, and polyurethane foam.

5. The floating connector according to claim 1, further comprising:

a positive stop configured to limit the inward displacement of the floating member, the positive stop including an aperture defined therein having an internal dimension greater than the mounting end of the connector and further having an internal dimension less than the dimension of the outer floating member, the positive stop being fixedly disposed to the support member along the inner perimeter of the opening.

6. The floating connector according to claim 5, further comprising a standoff disposed between the positive stop and the support member.

7. The floating connector according to claim 6, wherein the standoff is integral to the positive stop.

8. The floating connector according to claim 2, wherein the elastomeric coupling includes a plurality of elastomeric elements.

9. The floating connector according to claim 8, wherein the plurality of elastomeric elements are arranged in a mutually parallel configuration.

10. The floating connector according to claim 8, wherein the plurality of elastomeric elements are arranged generally orthogonally to a desired axis of motion of the floating member.

11. The floating connector according to claim 8, wherein an elastomeric element has a shape selected from the group consisting of substantially bar-shaped, substantially square-shaped, and substantially dot-shaped.

12. The floating connector according to claim 8, wherein the plurality of elastomeric elements are configured in a lattice arrangement.

13. The floating connector according to claim 8, wherein the motion of the floating assembly is substantially limited to a single axis of motion.

14. The floating connector according to claim 8, wherein the plurality of elastomeric elements are configured in a lattice arrangement.

15. A floating connector, comprising:

a floating member having a connector fixedly disposed therethrough, the connector including a mating end adapted to couple to a mating connector and a mounting end which mounts to the floating member;

a support member having an opening defined therein, wherein the floating member is substantially concentrically disposed within the opening;

a first semicircular recess disposed along an inner edge of the opening;

a second semicircular recess disposed along an outer edge of the floating member, the first semicircular recess and the second semicircular recess forming a substantially toroidal interstice therebetween; and

an elastomeric coupling fixedly disposed within the substantially toroidal interstice.

16. The floating connector according to claim 15, wherein the elastomeric coupling is an 0-ring captured within the substantially toroidal interstice.

17. The floating connector according to claim 15, wherein the elastomeric coupling is constructed from material selected from a group consisting of rubber, neoprene, nitrile, silicone, foam rubber, and polyurethane foam.

18. A floating connector, comprising:

a floating member having a connector fixedly disposed therethrough, the connector including a mating end adapted to couple to a mating connector and a mounting end which mounts to the floating member;

a support member having an opening defined therein, the opening including an internal dimension greater than the mounting end of the connector to define a clearance between the opening and the mounting end of the connector, the floating member and the connector positioned in substantial concentric alignment with the opening and wherein the floating member is substantially concentrically disposed within the opening;

a first semicircular recess disposed along an inner edge of the opening;

a second semicircular recess disposed along an outer edge of the floating member, the first semicircular recess and the second semicircular recess forming a substantially toroidal interstice therebetween; and

an elastomeric o-ring captured within the substantially toroidal interstice.

19. The floating connector according to claim 18, wherein the elastomeric o-ring is constructed from material selected from a group consisting of rubber, neoprene, nitrite, silicone, foam rubber, and polyurethane foam.
