Abstract

A garment is provided with a tube that may be used to facilitate placement of needle electrodes into a patient to facilitate intraoperative monitoring during surgical procedures.

Claims

1. A garment to facilitate the implantation of needle electrodes for intraoperative monitoring during a surgical procedure comprising:

a fabric having a thickness separating a skin surface adapted to reside proximate to the skin of a patient and a top surface opposite the skin surface;

at least one tube comprising an actuator, a spring, and a stop residing in the fabric between the skin surface and the top surface, the tube having a cover proximate the skin surface and a port in fluid communication with an interior of the tube to generate a pressure differential across the actuator such that the actuator and spring advance and retract the needle electrode; and

a needle electrode, whereby the tube is adapted to receive the needle electrode and the needle electrode is adapted to be inserted through the skin of the patient such that the needle electrode will be positioned proximate a nerve to be monitored.

2. The garment of claim 1 wherein the actuator is coupled to the needle electrode and is slidingly coupled to the tube, the actuator operatively coupled to engage the stop.

3. The garment of claim 2 wherein the actuator is a plunger.

4. The garment of claim 1 comprising a retractor coupled to the needle electrode and adapted to retract the needle electrode from a patient.

5. The garment of claim 1, wherein the actuator comprises a plunger and wherein pressure in the interior of the tube maybe be decreased through the port to reduce the pressure such that the actuator advances the needle electrode and pressure in the interior of the tube may be increased through the port to retract the needle electrode.

6. The garment of claim 1 wherein the garment is selected from a group of garments consisting of:

a glove, a wrist band, a sleeve, a shirt, a legging, a pair of pants, a cap, a body suit, or a combination thereof.

7. The garment of claim 6 wherein the fabric is selected from a group of fabrics consisting of:

gauze, foam, rubber, wraps, or cloth.

8. The garment of claim 1 wherein the cover has a convexly curved surface adapted to apply pressure to a wound.

9. The garment of claim 1 further comprising an air bladder proximate the cover such that inflating the air bladder applies pressure to the cover and is adapted to apply pressure to a wound to facilitate clotting.

10. The garment of claim 9 further comprising a diaphragm residing in the tube that forms a chamber in which the air bladder expands when inflated.

11. The garment of claim 10 wherein the air bladder causes the cover to form a convexly curved surface.

12. The garment of claim 1 wherein the tube is formed of a material selected from the group of materials consisting of a gel material or a rubber material.

13. The garment of claim 1 further comprising a cartridge contained in the tube.

14. The garment of claim 1 wherein a cartridge comprises the cover of a diaphragm defining a chamber that is filled with a penetrable material.

15. The garment of claim 1 wherein the needle electrode comprises a surface to cooperatively engage the stop.

16. The garment of claim 15 wherein the surface is selected from the group of surfaces consisting of:

a flanged surface or a flared surface.

17. A garment to facilitate the implantation of needle electrodes for intraoperative monitoring during a surgical procedure comprising:

a fabric having a thickness separating a skin surface adapted to reside proximate to the skin of a patient and a top surface opposite the skin surface;

at least one tube residing in the fabric between the skin surface and the top surface, the tube having a cover proximate the skin surface and a plunger opposite the cover slidingly received in the at least one tube;

a needle electrode; and

means for advancing and retracting the needle electrode, wherein the means for advancing the needle electrode comprises at least the plunger and a port in fluid communication with the tube, wherein the port at least one of feeds or bleds pressure to the interior of the tube to advance or retract the needle electrode, means for retracting the needle electrode, whereby the tube is adapted to receive the needle electrode and the needle electrode is adapted to be inserted through the skin of the patient such that the needle electrode will be positioned proximate a nerve to be monitored.

18. The garment of claim 17 wherein the means for advancing and retracting the needle electrode further comprises a compression spring and the port is in fluid communication with the tube to bled pressure from the tube whereby the spring expands as pressure decreases to advance the needle electrode.

19. The garment of claim 18 wherein the means for advancing and retracting comprises the port in fluid communication with a fluid supply to increase the pressure in the tube and compress the spring and retract the needle electrode.
