Abstract

The Light Cable Safety Sleeve is a safety product to be used in minimally invasive surgery or surgery that uses light cable/guide visualization. Light cable/guides emit heat creating a potential fire risk to the patients and surgical team. The Light Cable Safety Sleeve slides over the end of a light cable covering the tip and connection to a telescope or retractor on the sterile field, therefore, providing a protective barrier between the heated end of the cable and the patient's skin and or surgical drapes in the event of accidental disconnection. The Light Cable Safety Sleeve is a single use silicone sleeve with perforations on the shaft for heat release/dissipation, and shaped collars at each end for placement stability and suspension of the light cable and connection assembly (within the sleeve).

Description

THE LIGHT CABLE SAFETY SLEEVE
Field of the Invention
The Light Cable Safety Sleeve is a safety product for miirhnally invasive surgery or surgery that uses light cable/visualization. Surgical light cables are noted as a source of heat and ignition. The "Fire Triad" in the Operating Room describes three components necessary to produce a fire: heat and ignition source, fuel and an oxidizer. A fire during a surgical procedure can be ignited in approximately ten seconds when a light cable is plugged into a light source and powered on with an exposed distal end (caused from accidental detachment or premature ignition of the light source at the proximal end).
Most light sources are equipped with a "stand by" mode to temporarily prevent light and heat emission, without the need to turn off the light source. Light sources lie outside the sterile field" or area designated for the scrubbed surgical team which means that the circulating personnel manually control the ignition of the light cable at the proximal end or light source. Attention and immediate response on behalf of the circulating personnel would be required to prevent injury and/or fire hazard in the case of accidental disconnection.
The light cable safety sleeve covers the end of a light cable and telescope or retractor connection providing a protective barrier between the heated end of the cable and the patient's skin and/or surgical drapes. The safety sleeve provides more time for the surgical team to react in the case of accidental disconnection or premature ignition of the light source.
Description of Prior Art
A prior act to provide a safety receptacle for the light cable was developed by SensorMed Inc., and referred to as the CableCap required one of the scrubbed surgical team members to manually screw on and manually screw off the CableCap through out the procedure (i.e. screw the CableCap on the cable during set up of the surgical field, disconnect Cable Cap in order to connect the telescope to the light cable for light visualization, disconnect the telescope, and re-connect the CableCap to the light cable, at the end of the case). If the light cable and telescope/retractor became disconnected (i.e. either accidently or purposely for a telescope change) during the procedure the CableCap would not be in-situ to provide a protective barrier between the heated end of the light cable and the patient's skin and/or surgical drapes.
In contrast, the Light Cable Safety Sleeve is slid on the cable during surgical set-up of the case and remains in place for the duration of the surgical procedure providing a convenient and protective barrier in the case of accidental disconnection of the cable end from the telescope/retractor connection.
The CableCap protects only the initial point of connection on the light cable whereas the Light
Cable Safety Sleeve protects the cord and connection housed within the sleeve.
The CableCap has to be purchased in different sizes to adapt to each brand of light cable, whereas the Light Cable Safety Sleeve is a sleeve mat adaptable to all brands of light cables and connections.
Summary
The Light Cable Safety Sleeve is an easy to use product to manage the heated end of the light cable. It is designed to be slid on the cord (at set-up of the surgical field) and remain in place for the duration of the procedure. The one-piece sleeve design with collared ends protects Ihe cable end/connection housed within and provides a barrier between the patient and/or surgical drapes in the event of an accidental disconnection. The collared ends of the safety sleeve are both a different size to accommodate different sized light cable diameters and connection assemblies.

Description of the Embodiment
The light cable provides light visualization during surgery when it is plugged into a machine called a light source. The light transmits from the machine end (proximal end) to the connector end of the cable (distal end). The distal end of the light cables can generate up to 400 degrees of heat. The distal end of the light cable is screwed or pushed onto a lighted retractor or telescope to enhance visualization inside the body/body spaces. If the telescope isn't screwed or pushed on completely, or loosens during surgery (from movement), there is a possibility that the cord could disconnect at the distal end. The safety sleeve is designed to slide over the light cord and tip to protect the hot tip from touching anything, therefore, rninimizing the risk of harm in the event of a disconnection.
The safety sleeve is at least 2 inches long, as seen in Figures 1, 2 and 3. It is made of silicone material, similar in nature to the silicone rubber oven mitts, which are safe for very intense heat. The safety sleeve has vent holes on the sides of the sleeve to dissipate or release heat, generated from the light energy, as seen in Figures 1, 2 and more specifically as three rows of vent holes, as seen in example 5 of Figure 3.
Each end of the sleeve has two different sized collars to accommodate light cables wide and narrow light cable diameters as seen in Figure 1 and 2. The collar shape helps the cord slide on easily and stay in place when required- There are two different shaped collars that we have chosen:
1) a star-shaped collar with 6 points on one end and 7 points on the other, as seen in example 1 and 2 of Figure 1.
2) a modified diamond-shaped collar with four points on both ends, as seen in example 3 and 4 of Figure 2.
The safety sleeve is x-ray detectable.
The safety sleeve is a sterile single use item. No medical device reprocessing is required in the use of the safety sleeve.
The safety sleeve is to be placed on the distal end of the light cable during surgical field set-up (by the scrubbed OR team member), slid into place over the connection and left in-situ for the entire case to provide a barrier between the heated distal end of the light cable and connection assembly, and the patient and/or drapes. The safety sleeve would be disposed of at the end of the surgical case. The safety sleeve provides a resistance barrier (i.e. in the event that the light cable is dropped) for the light cable and connection assembly within the sleeve housing.
Alternative use
The Light Cable Safety Sleeve can also be used to protect the proximal end of the cable (that connects to the light source) by providing a resistance barrier within the sleeve housing, in the event that the light cable is dropped on disconnection. For this application, the sleeve diameter and length would need to be modified to accommodate the different sized cable connections (i.e. the sleeve would need to be longer in length and wider in diameter). The safety sleeve collar design would utilize the same options presented in example 1 and 2 of Figure 1 and example 3 and 4 of Figure 2. It would also be used in a similar manner for the proximal end of the light cable: The surgical team member would slide the safety sleeve on the light cable covering the proximal end at surgical field set-up, hand off the proximal end to the circulating OR team member who would slide the safety sleeve up the cable to expose the proximal end for insertioii into the light source. At the end of the procedure, the circulating OR team member would slide the safety sleeve down over the proximal tip at disconnection from the light source.
