Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates generally to a fiberoptic coil tray and carrier package, and more particularly pertains to a fiberoptic cable coil tray and carrier package, and a method of packaging a fiberoptic coil, wherein a plurality of fiberoptic coil retainer notches or clips are formed on select portions of the carrier to provide a stable, self-contained and restrained coil which remains properly seated in the package during handling and storage. The carrier provides increased ease of handling of the fiberoptic coil by restraining the fiberoptic coil with the plurality of separate retainers which are positioned along the length of the fiberoptic coil until it is used, such that a selected length of the fiberoptic coil can be removed from the carrier without the remaining coils springing out therefrom.

[0003] The fiberoptic coil package consists of a tray, a carrier to which the fiberoptic coil is attached and which is inserted into the tray, and a lid for the tray. The carrier coils the fiberoptic cable and secures each end thereof, such that either end can be removed separately while the remainder of the fiberoptic coils remain secured to the carrier. Features of the tray and carrier restrain the coiled fiberoptic cable to provide for easier handling of the coiled fiberoptic cable and to decrease the likelihood of the coiled fiberoptic cable springing out when the package is opened.

[0004] 2. Discussion of the Prior Art

[0005] A fiberoptic cable is one component of a medical device which must be handled gently and in a sterile fashion throughout a surgical procedure. The fiberoptic cable is generally packaged and shipped as a coil. The entire length of the coil must be controlled to avoid contamination, and the diffuser end of the fiberoptic must be handled with caution to avoid breakage. The length of the coiled fiberoptic cable (8-10 feet) and the spring-like tendency of the fiberoptic coil create problems with control and handling of the fiberoptic coil. Additional limitations on the packaging include the need to maintain a minimum bend radius of the fiberoptic coil and the need to provide EtO (ethylene oxide) sterilization rather than sterilization by gamma irradiation.

[0006] The current fiberoptic product is packaged as a multi-loop coil held together with twist-ties. The coil is placed in a protective tray with a snap-on lid. The connector end and the tip end of the coil are held at different corners of the tray via snap-lock retainers. The entire assembly is contained within a flexible sterile pouch.

[0007] To unpackage the current fiberoptic coil, the surgeon/user removes the fiberoptic coil from the tray, removes the nylon clips from the coil, hands one end to a technician, and threads the opposite end into an endoscope. However, the entire length of the fiberoptic coil must be controlled by hand as soon as the nylon clips are removed.

[0008] The current fiberoptic coil package, while useful for holding the fiberoptic coil, is cumbersome, and makes it difficult for the user to remove the fiberoptic coil. The current package has two pieces, a lid and a tray. The lid is removed, and the fiberoptic coil is disassembled from the tray and is then uncoiled. The current fiberoptic coil packaging (tray lid with straight crimped-on tip protector) makes the fiberoptic coil difficult to remove.

SUMMARY OF THE INVENTION

[0009] Accordingly, it is a primary object of the present invention to provide a fiberoptic coil tray and carrier package, and a method of packaging a fiberoptic coil, which provides a stable, self-contained and restrained fiberoptic coil without the need for nylon cable ties, and without the risk of the fiberoptic coil springing open out of the package as it is being opened.

[0010] The subject invention makes unpacking of the fiberoptic coil easier by maintaining a more stable coil with a plurality of integral parts, rather than with external cable ties as in the prior art, and makes it easier to remove a fiberoptic coil in its wound state.

[0011] The fiberoptic coil package comprises a tray, a carrier to which the fiberoptic coil is attached and which is inserted into the tray, and a lid for the tray. The carrier coils the fiberoptic cable and secures each end thereof, such that either end can be removed separately while the remainder of the fiberoptic coil remains in a coil on the carrier. The carrier has an attachment such as a clip which may be used to attach the assembled carrier and fiberoptic coil to a surgical drape on a patient being treated. The carrier is sterilized and packaged in a blister tray with a lid such as a Tyvek lid.

[0012] The present invention provides an improved package for the next generation of fiberoptic coil with an improved tip protector, wherein the fiberoptic coil consistently remains properly seated in the package tray during shipment. Molded features of the carrier restrain the coiled fiberoptic cable to greatly decrease the likelihood of the tip springing out when the lid is removed from the tray.

[0030] FIGS. 7 is an exploded view of a preferred embodiment of a combined packaging tray 96 and fiberoptic coil carrier 98 designed to secure and package a coil of fiberoptic cable, wherein the top portion of FIG. 7 illustrates a separated Tyvek lid 100, the middle portion of FIG. 7 illustrates just the fiberoptic coil carrier 98 securing a coil of fiberoptic cable thereto, and the bottom portion of FIG. 7 illustrates just the packaging tray 96.

[0031] Referring to FIG. 7, the blister tray 96 has a rectangular form, and is preferably thermoformed from clear PETG plastic. The blister tray has a bottom surface 101, sidewalls 102, and a flange 103 at the top of and extending around the sidewalls. The bottom surface is generally flat with raised studs 105 and I-shaped relief areas 104 defining a depression to receive the I-shaped carrier 98. The relief areas accommodate the larger components of the fiberoptic cable such as the connector handle, and provide sufficient room and clearance to allow fingers to grasp and remove the carrier. The carrier 98 and fiberoptic coils are supported by plateau surfaces 115, with the raised studs 105 rising above the plateau surfaces 115, and the relief areas 104 being below the plateau surfaces 115. The tray is configured to create a stable horizontal base having the shape of a large I which does not tip or rock when the tray is placed on a tabletop or stacked in multiples. The raised studs 105 maintain the carrier in position within the tray and provide support for the Tyvek lid 100 which is sealed to the flange 103 extending around the upper perimeter of the sidewalls 102. One flange corner 106 is recessed slightly, to provide an unsealed corner piece of the Tyvek lid 100 which is suitable for grasping to pry the Tyvek lid away from the blister tray.

[0032] FIG. 8 is a perspective view of just the fiberoptic coil carrier as shown in the middle of FIG. 7 but without an optical fiberoptic coil positioned thereon and without a spring clip thereon, and illustrates more clearly the molded contour of the carrier. Referring to FIGS. 7 and 8, the carrier 98 is generally flat, and is preferably thermoformed from clear or white PETG or high-impact polystyrene plastic. The exterior profile and I-shape thereof is shaped to fit within the sidewalls 102 and studs 105 and on top of the plateau surface 115 of the blister tray. Possible configurations for the carrier 98 include a cross, a Y shape, or the general shape of the letter I, as shown in FIGS. 7 and 8. Raised ribs 107 and a channel 108 near the center of the profile provide rigidity for the carrier. The uppermost area of the I has an attachment means, shown as a spring clip 114, which provides for attaching the carrier to a surgical drape.

[0033] The connector handle end 116 of the fiberoptic coil is seated in an uppermost area of the carrier in a recess 110 which is shaped to generally match the profile of the connector. Two thermoformed posts 111 directly across from each other are formed with a negative profile to match the circular barrel of the connector, to retain the connector barrel in place therein. The carrier 98 retains the fiberoptic cable in a coiled configuration by multiple snap fit recesses 112 located in the ribs. Each snap fit comprises a series of three (3) offsets which are formed with a negative degree draft which matches the profile of the fiberoptic cable while allowing ample room for ease in the forming process. The lowermost snap-fit recess in the top portion of the carrier at 113 has a larger size in order to secure therein the tip protector assembled to the treatment end of the fiberoptic cable. The fiberoptic coil is maintained at a diameter which is sufficiently large to allow long-term storage of the fiberoptic cable without inducing stress which might degrade the fiberoptic cable strength.

[0034] The carrier 98 can be securely attached to a surgical drape by a spring clip 114 at the top portion of the carrier. The attachment at 114 is centered side-to-side with respect to the center of gravity of the assembled carrier and fiberoptic coil so that the carrier will not skew to one side when hanging from the attachment. The clip can be formed of a combination of sterilizable metal and plastic materials such as a spring device (BGR, part number 2115). Alternatively, the attachment of the carrier to a surgical drape can be by an adhesive area or strip which adheres to the surgical drape. In one embodiment, the top portion of the carrier can fold back upon itself to enclose a portion of the drape and lock together via a mating stud and a hole.

[0035] The packaging concept of the present invention provides increased ease of handling of coils of fiberoptic cable by retaining the fiberoptic coils at a plurality of separate areas along the length of the fiberoptic cable until it is ready to be used. Each of the connector and treatment ends of the fiberoptic coil are separately retained, and can be removed and handled separately, while the opposite end and/or excess length are retained and controlled in the carrier. The sterile device can be conveniently accessible to a surgeon by clipping the carrier onto the surgical drape of a patient.

[0036] The carrier 98 of FIG. 7 can selectively incorporate therein features from the embodiments of FIGS. 1-6, particularly the carrier features of FIGS. 2, 4, 5 and 6.

[0037] The blister tray 96 with a sealed Tyvek lid 100 provides for sterilization of the carrier/fiberoptic coil assembly in the lid-sealed blister tray. This sterilization can be, for example, by ethylene oxide which is particularly suitable in the sealed tray, electron-beam radiation, gas plasma or pulsed light.

[0038] The tray 96 is not specific to a particular carrier for a particular surgical device, and can accommodate any standard sized fiberoptic coil carrier regardless of the features required to retain the fiberoptic coils. The exterior bottom of the tray 96 is designed to allow easy stacking of multiple trays in a stable manner without the stack becoming skewed or tipping over.

[0039] Each carrier 98 is generally designed and contoured to be specific to a particular surgical device, and is configured to retain the device until it is removed for usage. The carrier can be attached to the surgical drape of a patient, such that it is positioned conveniently to and requires a minimum of handling by the surgeon.

[0040] The entire package of carrier 98, tray 96 and Tyvek lid 100 is cost competitive with alternate package configurations which utilize multiple thermoformed blisters and/or pouches. The assembly secures a proper coil configuration for long term storage of the fiberoptic coil, and maintains the fragile working ends thereof in a stable, protected manner to prevent breakage during shipping, handling and removal.

[0041] While several embodiments and variations of the present invention for a fiberoptic coil tray and carrier package are described in detail herein, it should be apparent that the disclosure and teachings of the present invention will suggest many alternative designs to those skilled in the art.
