Abstract

An electrical medical device assembly that includes a handheld unit, adapted to be manipulated by a medical professional and requiring multi-conductor electrical connection to a base unit; a base unit adapted to provide electrical power to the handheld unit; a multi-conductor electrical cable connecting the handheld unit to the base unit; and a multi-conductor electrical connector interposed between the handheld unit and the base unit, the connector including a first half and a second half and wherein relative rotation is permitted between the first half and the second half.

Claims

1. A method of performing a surgical procedure using an electrical surgical device, comprising:

(a) providing an electrical surgical assembly including said surgical device connected to a base station by a cable having a plurality of mutually electrically insulated conductors, and an electrical connector interposed at a point between said base station and said device;

(b) wherein said connector is comprised of a first half and a second half that, when connected together, have freedom of rotation relative to each other; and

(c) performing said surgical procedure and permitting said connector to permit said relative rotation thereby avoiding a problem of cable twisting.

2. The method of claim 1, wherein said first half of said connector is fixed into said base station.

3. The method of claim 1, wherein said surgical device is an angioplasty catheter.

4. The method of claim 1, wherein said surgical device is an electric scalpel.

5. The method of claim 1, wherein said connector said cable comprises a first cable portion and a second cable portion and wherein said connector is interposed between said first cable portion and said second cable portion.

6. An electrical medical device assembly, comprising:

(a) a handheld unit, adapted to be manipulated by a medical professional and requiring multi-conductor electrical connection to a base unit;

(b) a base unit adapted to provide electrical power to said handheld unit;

(c) a multi-conductor electrical cable connecting said handheld unit to said base unit; and

(d) a multi-conductor electrical connector interposed between said handheld unit and said base unit, said connector including a first half and a second half and wherein relative rotation is permitted between said first half and said second half.

7. The assembly of claim 6, wherein said first half of said connector is fixed into said base station.

8. The assembly of claim 6, wherein said surgical device is an angioplasty catheter.

9. The assembly of claim 6, wherein said surgical device is an electric scalpel.

10. The assembly of claim 6, wherein said cable comprises a first cable portion and a second cable portion and wherein said connector is interposed between said first cable portion and said second cable portion.

11. The assembly of claim 6, wherein said first half of said connector defines a set of contacts having circular conductive surfaces and wherein said second half of said connector includes a set of resilient contacts, each positioned to contact one said circular conductive surfaces to create an electrical connection.

12. The assembly of claim 11, wherein each of said circular conductive surfaces is contacted by a single resilient contact.

13. The assembly of claim 11, wherein said circular conductive surfaces are concentric and said resilient contacts are spring-loaded pins.

14. The assembly of claim 11, wherein said circular conductive surfaces are stacked and said resilient contacts are bent metal sheets.

15. The assembly of claim 13, wherein said second half of said connector clamps around said first half.

16. The assembly of claim 11, wherein said circular conductive surfaces are stacked and said resilient contacts are resilient horseshoe shaped elements.

17. A connector comprising:

(a) a first half that defines a plurality of contacts having circular conductive surfaces; and

(b) a second half that includes a set of resilient contacts, each positioned to contact one of said circular conductive surfaces to create an electrical connection.

18. The connector of claim 17, wherein said circular conductive surfaces are concentric and said resilient contacts are spring-loaded pins.

19. The connector of claim 17, wherein said circular conductive surfaces are stacked and said resilient contacts are bent metal sheets.

20. The connector of claim 19, wherein said second half of said connector clamps around said first half.

21. The connector of claim 17, wherein said circular conductive surfaces are stacked and said resilient contacts are resilient horseshoe shaped elements.
