Abstract

Surgical sutures, including ligatures, are wound from a needled or free end on a printed reel-label. The reel-label is made from sealed together thicknesses of stiff inert sterilizable label stock, with means, such as an aperture or grommet, to act as a rotable axis to permit holding between a finger and thumb for unwinding. A needle, if attached, is held in a pocket between the thicknesses with the armed portions of the needle protected. The friction between the thicknesses and the suture permits retention of the suture during storage and unwinding from either end. The suture reel assembly is stored in a sterile envelope which may be completely dry. The thus formed package protects the suture from kinks during storage, it protects the suture from the needle and the package from the needle. It permits unwinding from either end without tangling and it is capable of being rewound.

6 Claims, 16 Drawing Figures SUTURE REEL-LABEL PACKAGE BACKGROUND OF THE INVENTION In this modern day of convenience packaging, more and more effort is being put into attempting to package in a form which is convenient and economical and which meets requirements for the particular item being packaged.

In the packaging of surgical sutures, it is necessary that the sutures be released in sterile condition, ready for use by the surgeon with the economic requirement that the packaging be as economical as consistent with the qualities required and to the extent possible that a minimum of number pieces and minimum quantity of packaging materials result from releasing the suture for use. A count is often kept to insure that each needle and each reel and envelope is removed from the operating field.

An acceptable package needs to be inexpensive and completely reliable. The package must release a sterile suture for the surgeon's use with his positive knowledge that the suture is, in fact, sterile and none of its design characteristics have been compromised during storage prior to use. Sutures may be stored in hospitals for several years before use, although the usual storage time is much shorter.

There are many sizes of sutures, and many materials of construction, such as catgut, or polyglycolic acid for absorables, and non-absorbables of silk, cotton, nylon, dacron, polyethylene, polypropylene, stainless steel, insulated stainless steel, and other materials of construction, There are several different needle types in common use, including pointed straight, pointed curved, three cornered straight, three cornered curved, both regular and reverse, and needles with side cutting edges of various types. The variations and combinations of each of these to meet the preferences of many surgeons for different operative procedures means that a suture manufacturer needs to supply different suture combinations running into the thousands. Some of these are fast moving items, others meet only with occasional demand. For purposes of convenience and storage in the hospital as well as economy of manufacture, it is highly desirable that as many suture combinations as feasible be packaged in a minimum number of different package styles and shapes and storage units. It is quite common to package three dozen identical sutures in a box. It is convenient to have most of the boxes about the same size and shape, so that the hospi tal may store them most conveniently. It is also convenient from the manufacturers standpoint to be able to reduce his inventory of box sizes and to be able to use the same components for the maximum number of suture combinations in the product line.

It is essential that a package for a side cutting needle; that is, a needle which has a sharp edge on the side, protect the suture from contact with the sharp side, or armed edge, ofthe needle which could partially cut the suture and to avoid having the sharp edges cut the package. Also, the armed needle edges need to be protected so as to maintain their sharpness.

Additionally, it is highly desirable that the needles and sutures be oriented in a consistent relationship within packages so that the using surgeon, directly, or the nurse who passes the sutures to the surgeon, will be able to rapidly and reliably grip the needle without having to take time to orient the needle with respect to the needle forceps at the time of use.

These requirements are so rigorous and of such importance that many different package designs have been tried, some have been used, and many have been found wanting in one or more particulars.

Most of the suture packages today are strippable, double envelope packages of the type first disclosed in U.S. Pat. No. 3,043,067, Rynkiewicz and Ayres, Suture Package, July 10, 1962.

The outer envelope and certain details are disclosed in U.S. Pat. No. 2,949,181, Buccino, Suture Package And Process Of Making Same, Aug. I6, 1960.

U.S. Pat. No. 3,357,550, Holmes and Murphy, Combination Reel And Label For Surgical Sutures", Dec. 12, I967, shows a system in which the reel also serves as a label with the reel being torn apart to release the suture wound on the label.

U.S. Pat. No. 3,376,973, Granowitz and Buccino, Package For Surgical Sutures, Apr. 9, I968, shows a molded plastic reel fitting in a hub for surgical sutures with the assembled reel, hub and suture being packaged in outer envelopes.

U.S. Pat. No. 3,038,475, Orcutt, Surgical Needles And Manufacture Of Same, June l2, l962, shows certain forms of surgical needles, including curved, triangular shaped needles with the edges being sharp or round and which sharp side edges can damage sutures or packages.

U.S. Pat. No. 2,84l,l 50, Riall, Cutting Edge Suture Needle, July 1, 1958, shows another type of side cut ting needle, the sharp edges of which can damage sutures or packages.

SUMMARY OF THE INVENTION It has now been found that a suture package meeting the requirements set forth above is advantageously formed from sheet label stock one side of which is coated with a thermoplastic adhesive, such as polyethylene, with either a single sheet of such a material being doubled on itself to provide two thicknesses, or two separate sheets of material being sealed together and appropriately folded, so that the suture is wrapped between at least two thicknesses of the label stock which are sealed together. The suture is retained between the two sheets of material sealed together, whereby the suture is held in position until time for use and the suture is readily unreeled from either end from between the two thicknesses of label stock. Conveniently. the needled end is placed first and the free end is wound around the reel-label. At the time of use, the needle is pulled free and the suture is unwound from the needled end with the various turns of the suture passing each other in the V-groove between the label stock thicknesses, without tangling and without compromise of suture quality.

In preferred embodiments of the invention, an additional thickness of label stock which may be transparent covers and protects the needle from contact with either the turns of the suture or the envelope. The needle is inserted in retaining means in the reel-label. The additional thickness of label stock covers the needle in such fashion that the covering portion can be turned back to release the needle in oriented relationship so that it may be picked up by the user in consistent orientation. Any of the usual types of needle forceps may be used.

The reel-Iable having the suture wound thereon may be packaged dry or in a selected tubing fluid in an interiorly and exteriorly sterile inner envelope. which inner envelope is packaged in a strippable outer envelope.

As is conventional in the art, the suture is served to a surgeon by stripping the outer envelope, and either with forceps. or by manually projecting, the inner envelope is passed across the sterile barrier, into the sterile areas of the operating room.

The inner envelope is opened at time of use.

As used herein, the term sutures includes ligatures. Ligatures technically are used without a needle for tying, whereas sutures are used with a needle for penetration of tissues as well as tying. The same material can be used for both purposes and frequently parts of the same strand are actually used as both a suture and a ligature depending upon the requirements of the surgeon at a particular time during a surgical procedure.

The sutures may have a needle on one or both ends. Frequently a needle is placed on each end so that the suture is cut and each needle used separately, and sometimes each needle is used for penetration for particular tissues at a particular time. Conveniently, the needles are of the eyeless type that is permanently attached to the end of the suture and designed for but a single use. Such needles cause less trauma to tissues in which they are used and are becoming surgically preferred.

The present invention is particularly adapted for the packaging of polyglycolic acid sutures. These are a new class of synthetic absorbable suture which is to be packed and stored dry. The requirement for dryness is disclosed in US. Pat. No. 3,728,839, Glick, Storage Stable Surgically Absorbable Polyglycolic Acid Products". Apr. 24, I973.

The sutures may be collagen, either natural catgut or regenerated catgut, which sutures are usually packaed in a conditioning fluid such as a mixture ofone or more alcohols in water so that the collagen will have a preferred flexibility Non-absorbable sutures may be packed on the present reel-label and include such materials as silk, silicone or wax coated, or cotton or linen, or one of the newer synthetic materials such as nylon, polyester. isotactic polypropylene, or linear polyethyl ene. stainless steel wire or other wire, either insulated or bare, or the suture may be of such other composition as preferred by the surgeon for the surgical procedure in progress.

The reel-label is preferably of a label paper which is manufactured for suture labels and is a sterilizable paper designed for either letter press or offset printing. A paper with a 90 lb. weight basis and designed to withstand heat, steam, or gas sterilization without discoloration, and which accepts alcohol and water insoluble ink is satisfactory. It is preferred that such paper be coated with about one-half mil of polyethylene so that it becomes heat scalable. Such paper is known in the trade and readily available. The sealing may be by heated dies. or heat may be internally generated by ultrasonic means.

The present reel-label is and remains as a single piece, so that there is only one piece for disposal. In a preferred embodiment, the inner envelope which en closes and protects the suture on its reellabel is notched and fits around the reel-label so that it may be breached starting at the notch and torn open without tearing the envelope into more than one piece so that the inner envelope is a single piece for discarding.

It is important that the various pieces be identifiable so that after an operation, the surgical team can reliably find and count all components of packaging as well as surgical needles to be certain that undesired foreign elements are not sewn into the patient at the time of use.

Time and motion studies show that the serving of a suture using the present reel-label is faster and more efficient than with conventional reels. Saving time reduces the time a patient is in surgery, and, hence, the duration of risk, risks, saves time of the medical operat ing team, and reduces time charges for the operatingtheater, all of which are conducive to better and more economical patient care.

The present reel-label can have size and type designations for the suture and needle. The reel itself as well as the envelopes and boxes used may be color coded to designate the type of suture material. and/or other useful information.

The present invention, and its advantages are also apparent from the detailed description of certain embodiments thereof which follow.

As shown in FIG. I, a reel-label is cut out and scored from a sheet of stiff material such as pound, sterilizable offset printing paper which has thereon a coating of one-half mil polyethylene so that it is heat scalable. The label is conveniently, but not necessarily, die cut from rolls of paper stock and conveniently may be cut out and printed in continuous rolls, except for a final cut which is made at the time the label is folded and sealed.

As shown in FIG. 1, with the printed side up and the polyethylene coated side down, face panel 21 has attached thereto along score lines a first and a second accordion pleat panels 22 and 23, to the second of which is attached the back panel 24. On the other side of the rectangular panel are the third and fourth accordion pleat panels 25 and 26. Conveniently, but not necessarily, the third accordion pleat panel 25 is just slightly wider than the fourth accordion pleat panel 26 so that. in folding, when adhesively united to the back panel, the edge of the fourth accordion pleat panel is just slightly back of the edge of the back panel to insure that no edges stick out which can snag a suture being wound on the reel-label, Conveniently. when the reellabel is being cut, score lines are formed where the panels are to bend to insure that the bending occurs at a designed fold line.

To the top and bottom of the face panel and the back panel are attached ears, respectively, the top face panel ear 27, the bottom face panel ear 28, top back panel ear 29, and the bottom back panel ear 30. These ears are attached to the respective panels with score lines 31 being stamped into the label stock at the time of cutout. These score lines permit accurately positioned folds to be readily made between the panels. A tab notch 32 is formed in each of the four ears. A tab 33 is cut on three sides near the top and bottom of each ofthe face and back panels pointing towards the center of the panels.

As shown in FIG. 2, the four ears are folded inwardly against the face and back panels with the adhesive coated sides coming into the contact and similarly the accordion pleat panels are folded inwardly from each panel so that the face and back panels can then be folded towards each other, as shown in F103, with the adhesive of the face and back panels being sealed to each other at the tabs, through the tab notches 32, in the upper tab seal zone 34 and the lower tab seal zone 35. This holds the face and back panels together in resilient spring-like configuration. The face and back panels and united with side seal zones 36 on each side which adhesively unite the accordion pleat panels to the face and back panels for the length of the accordion pleat panels and adhesively unite the panel ears to the respective panels. The seals may be formed consecutively or concurrently.

The ears are advantageously fractionally smaller than the face and back panel to which they are adhesively united. Conveniently, they may be about a sixty-fourth of an inch narrower, so that allowing for manufacturing tolerances in cutting and folding the ears, the ears are necessarily slightly back from the face and back panels so that no corners protrude on which the suture can be snagged. The corners may be slightly rounded to reduce the chance of snagging.

The back panel has four intermediate radius rounded corners 37. The face panel has diagonally oriented two smaller radius rounded corners 38 and two diagonal larger radius rounded corners 39. By having the larger and smaller radii on the front face, as the reel-label is assembled, two corners have the face panel protruding slightly beyond the back panel so that they may be lifted easily with the finger and the other two corners with a larger radius and, hence, are slightly back of the back panel so that on each of the corners, one of the panels may be conveniently manipulated to open up the winding notch 49 between the panels.

Near the center ofthe face panel is a face panel rotating hole 40 and near the center of the back panel is a back panel rotating hole 41. These holes extend through the panel so that in unwrapping the suture, the surgeon may hold the reel-label with the thumb and a finger on each side and touching throuch the hole to permit the reel-lable to rotate during release of the suture. Preferably, the rotating hole is of a rounded poly gon configuration. As shown, it is conveniently a diamond shaped hole with rounded corners. By having the hole other than round, the suture reel-labels may be mounted on a spindle and positively driven by a nonround spindle which is shaped to match the rotating hole. Conveniently, a diamond shaped hole with rounded corners is used but a hexagonal, triangular, or other shaped hole may be used for the purpose if desired.

A separate needle protective cover 42 is cut from similar stiff label paper of 5 size and shape to nearly cover the face of the assembled panels with a cover seal flap 43. The needle protective cover is sealed along one edge to position the cover seal flap close to the face panel of the reel-label assembly, as shown in FIG. 5. One corner of the needle protective cover is a lifting corner 44 which extends slightly beyond "the face panel so that it may be lifted by the thumb of the user.

Identifying indicia 45 may be printed on the needle protective cover. Conveniently, but not necessarily, a cover rotating hole 46 is formed in the needle protective cover so that the cover may be either in the closed position or in the open position as the reellabel is rotated to unwind a suture.

The needle protective cover may also be of a trans parent material, for example, a mylar polyethylene laminate which permits inspection of the needle and suture while protecting the needle and suture. If trans parent, the identifying indicia may either be printed on the needle protective cover or on the face panel of the reel-label.

In FIG. 7 is shown a curved needle 47 which is inserted through the cut-out notch of the tab 33 so that the needles extend between the tab and the panel car. This keeps the needle away from the suture and holds it in a positively oriented position until time of use. The suture 48 extends from the curved needle 47 and is wound up and into the winding notch 49 which winding notch is formed by the tabs sealed together in the tab seal zones at the top and bottom and the accordion pleated panels on the edges. The suture may be wound in this winding notch by wrapping the suture in either direction with the free end being wound down into the notch or left free. At the time of use, the needle may be removed from its pocket and unwound with the turns of the suture passing each other in the winding notch.

By having the suture fit in the winding notch 49 in such fashion that turns can pass each other. the suture may be wound or unwound from either end at any time. This permits placing the needle 47 first, and winding the suture in the winding notch without slack and yet without tension. The needle pocket 50, which is formed by the cut-out for the tab 33 and the panel ear, permits a needle to be placed between two thicknesses of the panel stock and out of contact with the suture independently of whether the needle is curved. straight, triangular in cross-section, or duck-billed with sharp sides, the needle pocket provides a receptacle in which the point may be placed and the diagonal from the pocket is long enough for the entire needle to be placed between the face panel and the needle protective cover 42.

If the tabs 33 are narrower than the tab notches, the reel-label is easier to assemble and has more resiliency. If the tab is slightly wider, the needle is necessarily more certainly diverted from passing into the winding notch rather than being retained between the face panel and the face panel ear.

For those packages in which the suture is doublearmed, that is, has a needle on each end, a pocket at the top and a pocket at the bottom can be used, one for each needle. Alternatively, both needles may be placed in the same pocket.

In FIG. 8 is shown the suture wound between the accordion pleat panels. In this, as in other figures. the thickness of the panel stock is exaggerated for clarity.

The niceties of having the radii of curvature on the face panel and the back panel different in each corner and having all corners slightly rounded, and slightly smaller so that even with manufacturing tolerances, none of the ears or accordion panels stick out enough to snag the suture are features which are preferred for the best practice of the invention. For many purposes, a less refined reel-label may be adequate.

The cover 42, as well as the paper stock from which the panels are formed, may be colored in order that the color of the reel-label give a clue as to the type of suture material wound around. Similarly, the suture size, the suture material. and the type of needle may be printed on the needle protective cover on the face panel or the back panel. Usually. to avoid confusion, a minimum of printing is desirable in order that the user may very rapidly identify the data which is needed and not be too confused with extraneous information.

The size of the reel-label is, of course, commensurate with the size of the suture and its needle. Conveniently, a face panel which is 2 7/16 inches long and 1 /4inches wide gives good results. The radii of carvature of the back panel can conveniently be about a quarter of an inch whereas the smaller radius can be one-sixteenth inch and the larger radius three-eighths inch on the face panel with the ears one-sixty-fourth inch less on each corner. The accordion folds are conveniently a quarter of an inch for the first and second accordion pleat and a sixty-fourth of an inch more for the third accordion pleat panel and a sixty-fourth of an inch less for the fourth accordion pleat panel. Such a size permits sutures normally in use in a hospital to be conveniently packaged. For metric countries or where desired, panels may be varied considerably in size to accommodate sutures of selected sizes and appropriate needles.

In FIG. 9 is shown the reel-label with the needle protective cover attached in a notched tearable inner envelope 51 in a strippable outer envelope 55. The inner envelope may conveniently be made of a moisture proof material such as a 25 pound. calendered, bleached. pouch paper laminated with about a half a mil of polyethylene to a metallic foil such as about a one mil aluminum foil which is again laminated to one mil polyethylene as an inner sealable layer. Such a material is disclosed in U.S. Pat. No. 3,728,839, supra. Such material is essentially moisture proof so that synthetic absorbable sutures such as those of polyglycolic acid are protected from hyrolytic degradation. The same material may be used for the packaging of catgut sutures which are packaged with a desired quantity of water to maintain plasticity. Some sutures in which the moisture content is immaterial may be also packaged in the same material to maintain consistency of packaging standards.

By having a peaked sea] 53 and a tearing notch 52 therein, when the inner envelope is to be opened, the user can use the tearing notch as a start, and tear the laminate longitudinally along the face of the reel-label as shown in FIG. 10 so that without detaching the torn portion, the suture on the reel-label can be removed with forceps 54 or with the gloved fingers to release the reel-label having the suture thereon for use.

The notched tearable inner envelope 51 is packaged in a strippable outer envelope 55 of the type disclosed in U.S. Pat. No. 2,949,181, supra.

A modification of this invention is shown in FIG. 11. As shown in FIGS. 15 and 16, a round reel 56 is formed from sealing together a round face panel 57 and a round back panel 58 with an annular seal 59. The annular seal is inside the periphery ofthe face and back panels. As shown in FIG. 16, this leaves an external notch in which the suture is wound. As shown in FIG. 15, a threading notch 60 is formed in at least one of the panels in order that one or more needles 61 may be placed in an internal slit 62 with the suture 63 being wound into the winding notch formed between the round face panel and the round back panel.

From the constructional standpoint, the panels may be sealed together before the round face pane] and the round back panel are cut out from larger stock.

As shown in FIG. 16, conveniently, an X-ray opaque grommet 64 may be inserted to hold the panels together and also serve as a turning axis for unreeling the suture. The metal grommet gives positive indication by X-ray ifa package is accidentally dropped into an incision during an operation.

In FIG. 13 is shown a similar type of reel except that the face panels are rectangular and long enough so that a straight needle 65 can be inserted into the retaining slit 66 with the rear end being held in a positioning slit 67. In this modification, an annular seal 68 is used to hold the panels together and a square hold 69 is used for a rotatable axis. The square hole has the advantage that it may be used on a square drive shaft in winding 16 turns, depending on length, to wind a suture onto the present reel-labels. It is convenient to have one or more suture reel-labels ganged on a single spindle with the needles being inserted into the needle pockets. All of the sutures are wound on the reels by mechanically turned spindles simultaneously. Gang winding permits saving of time and effort, even though winding eight turns by hands is comparatively quick.

The use of rectangular reels gives a larger printing surface for identification of the suture type, size, and needle. Additionally, it provides a longer diagonal so that long straight needles can be inserted in the pocket and protected for their entire length. A rectangular reel permits the use of a rectangular envelope which maintains the orientation so that the user can expect to find a needle in the same relative position with respect to the envelope each time the sterile inner envelope is opened. This permits more raipd seizing of the needle with needle forceps with positive knowledge that orientation is as planned.

By having no sharp corners around which the suture is wound, even sutures which tend to attain a permanent set are curved minimally when unreeled for use.

By using the cover and having the needle point between the face panel and a face panel ear, the needle is positively positioned and is protected during winding so that the needle neither harms the suture nor the envelope nor has its sharpness compromised during the assembly and storage prior to actual use. The light frictional crimp from the sealed together panels permits as many as three sutures to be wound on a single reel and yet each one can be positively unwound without tangling. It also permits a longer length material to be wound for use as ligatures.

A radio opaque or magnetic grommet or ink permits detection of the package should it be inadvertently dropped into an incision.

By only having one part to the reel, the number ofextraneous pieces in the operating theater are reduced. It permits more positive counting in and out of the operating room of each of the elements of packaging to insure that all needles and extraneous items are accounted for before an incision is closed. The paper stock from which the panels are made, as well as the envelope, are free from traps which would pick up and retain contaminants and are readily sterilized by conventional sterilizing procedures. The package is such that any sterilizing cycle which is adaptable to the suture may be used. The package, for instance, will stand heat, dry or wet, ethylene oxide, radiation, ultrasonic vibration, or other sterilizing agents or combinations of these. The reel-label and package are sufficiently sturdy that only the characteristics of the suture material need to be considered as controlling parameters during packaging, sterilization, and storage.

Whereas, it is usually most convenient to cut the reellabel blank of HO. 1 from strip material and fold on score lines to form the finished reel-label, the face and back panels and accordion pleats as well as ears may be cut from separate strips or cut out as separate panels and adhered together. For constructions such as shown in FIGS. 13 and 15 where the edges of the panels extend beyond the annular seals, it is essentially necessary that separate panels be used. The feasibility of using folded panels is an alternative that must be placed in its proper economic context with, of course, the cost of each method of operation being considered before the final decision is made.

The reel-label may be made of plastic, or a plastic laminate, or foam, or paper of unique characteristics as well as conventional label stock.
