Description
Feb. 21, 1961 M. DEKER SURGICAL SPONGE Filed Dec. 30, 195'?- 2 Sheets-Sheet 1 ATTORNEY Feb, 21, 1961 M. DEKER SURGICAL SPONGE 2 Sheets-Sheet 2 Filed Dec. 30, 1957 INVENTOR flr/Aem DEA EA ATTOR NEY SURGICAL SPONGE Deker, New Brunswick, N.J., assignor to Johnson & Johnson, a corporation of New Jersey Filed Dec. 30, 1957, Ser. No. 705,948 16 Claims. (Cl. 128296) Marta The present invention relates to surgical sponges and more particularly to surgical sponges having a rounded contour and to a method of manufacturing the same.
In the surgical field, there is a demand for dressings adapted to be used Within the body in surgical operations. These may be used for stanching the flow of blood, apply ing medication, separating or removing tissue, or other uses to which the surgeon may wish to put them. These dressings are generally referred to as surgical sponges.
Surgical sponges may be of various shapes and sizes. It is important, however, that the sponge contain no loose threads or fibers that may become detached fromthe sponge during its use.
Sponges having a rounded contour are especially useful for fitting into body cavities, the application of medication, or use as a blunt instrument for the separation of body tissues or removal, through friction, of tissue segments. For this latter use, a surgical sponge is preferred that is substantially harder and more dense than the surgical sponges used for stanching the flow of blood.'
One of the objects of the present invention is to make surgical sponges of a design that can be readily adapted for the preparation of soft highly absorbent sponges or the preparation of relatively dense compact surgical sponges. A further object is to formrounded sponges of simple design so that they can be manufactured without the need of complex machinery.
These and other objects are accomplished by forming the sponge in a U-shape wherein a roll of absorbent material is first prepared-and then the roll is bent on itself tobringthe endstogether. The ends are then secured by any suitable means, cementing, tying, stitching, etc.
The absorbent roll from which the sponges are made may be a preformed cellular rod such, for example, as rolls of synthetic cellular sponge material, 'suchas polyurethane foam sponge, synthetic cellulose foam sponge or other preformed absorbent roll or may be specially prepared as hereinafter described.
It is generally highly desirable that surgical sponges have some X-ray opaque indicator so that the same may be readily detected if inadvertently left within the body. Although sponges are always counted both before and after an operation, the feature of X-ray detectability is very important andgives an excellent check, particularly where there maybe some doubt as to the count. The sponges of the present invention are readily'made X-ray detectable either by including within the roll a strip or thread of X-ray opaque material or by using an X-ray opaque cement When securing theends' offthe sponge together. i' In order to better understand the practice of the invention, attention is called to the drawings in which:
Figure 1 illustrates an absorbent roll or rod prior to forming into the sponge of Figure 2; g
= Figure 2 illustrates a sponge made from a roll of abso rbent material wtih sub-figures (a) through le) illustrating different ways of securing the ends together;
ice
Figure 3 is a tapered absorbent roll or rod used for forming the sponge of Figure 4;
V Figure 4 is a sponge made from a tapered roll;
Figure 5 is a sponge formed from a roll of folded gauze in which the center of the roll contains further absorbent material; and V Figure 6 (a) through (g), illustrates the steps in preparing a surgical sponge in'accordance with the preferred practice of the presentinvention.
Referring to the drawings, the basic sponge construction of the present invention comprises a roll 10 of absorbent material bent into the form of a U and having its ends 11 and 12 secured together. The roll may be formed of any suitable absorbent material which does not have loose fibers. Materials found to be suitable are synthetic cellular sponge materials, cotton rolls, if the cotton is covered by a woven fabric or a non-woven fabric in which the fibers are sufficiently bonded so that they will not come loose in use, rolls of surgical fabric or rolls formed in the manner hereinafter described.
In order to make the sponge X-ray detectable, an X- ray opaque insert may be placed in the sponge. This may be in the form of a thread or strip 13 passed through the roll so as to be enclosed within the same. The ends of the sponge may be secured together by any suitable means, various manners of securing the ends 11 and 12 being illustrated in Figure 2, sub-figures (a) through (e). In Figure 2(a), the ends are secured by cementing as illustrated at 14. In Figure'2(d), the X-ray opaque member 13 is of thermoplastic material. The endsof the X-ray opaque member extend beyond the ends 11 and 12 of the absorbent roll 10 and are bent over between the ends of the roll. Heat and pressure are then applied to melt the X-ray detectable material and fuse the ends 11 and 12 together.
In Figure 2(a), the ends 11 and 12 of the absorbent roll 10 are secured together by extending the ends of the X-ray opaque member 13 beyond the roll ends 11 and 12 and then securing the ends together at 16 either by tying or cementing or by fusing where the X-ray opaque member is formed of a thermoplastic material. If desired, a non-X-ray opaque thread or strip may be used inthe manner of 13 in Figure 2(e) to bond the ends 11 and 12 of the sponge together. This may be combined with an X-ray opaque material, as by impregnating a portion of a non-X-ray opaque strip with an X-ray opaque substance. With such structure, the X-ray opaque portion would preferably be enclosed in the sponge body.
In Figure 2(2 the ends 11 and 12 of the absorbent rollare secured together by Wrapping with thread 17. Wherethe ends are secured by wrapping with thread, it is preferable to also use a cement to secure the thread to the sponge to assure its not coming loose while the sponge is being used. Since useof a relatively soft cement has certain advantages in that there is less chance for damage to body tissues, it is frequently desirable to use both the thread wrapping and cement together rather than to only cement the ends as done in Figure 2(a).
In Figure 2(c), a still further modification is shown in which the ends 11 and 12 of the absorbent roll 10 are taped together with an adhesive-coated tape 18. In the embodiment shown, the tape is brought together above the end of the sponge, as illustrated at 1? to form a tab. The tab is preferably short where the sponge is of the hard or compact type. For the softer absorbent type sponge, the tab is'preferably sufiiciently long to facilitate holding.
Any cement may be used that is relatively insoluble in body fiuids'and non-irritating to body tissues under operating conditions. The cement should also be able to with? stand sterilizing conditions. Among cements suitable for this purpose are the polyvinyl chloride and polyvinyl chloride copolymer latexes'. Also, any X-ray opaque element may be used that is not harmful 'to the body under the conditions of use. Suitable materials, for example, may be thermoplastic threads or strips of cellulose esters, vinyl chloride polymers, polymers of acrylic acid and polymers of acrylic acid esters and their derivatives which have dispersed through them very finely divided particles of an X-ray opaque material such as barium sulfate.
The sponge of Figure 4 is similar to that of Figure 2, the primary difference being that the sponge of Figure 4 is formed of a tapered absorbent roll having a configuration similar to that shown in Figure 3. Theends 20 and 21 of the roll can be bonded together in any of the manners described for the sponge of Figure 2. Also, the sponge of Figure 3 would preferably contain an X-ray opaque thread or strip 22. This X-ray detectable member may be used for securing the ends 20 and 21 in the same manner as illustrated in Figure 2.
The preferred practice of the invention is illustrated by Figures and 6, Figure 5 illustrating the formed sponge and Figure 6 illustrating the various steps of forming the same. When the surgical sponge is formed in this manner, a wide degree of control can be exercised to form sponges of high absorptive capacity or sponges which are relatively hard and dense, depending on the final use to which the surgical sponge is to be put.
The sponge of Figure 5 is formed as follows: Two opposed edges 23 and 24 of a piece of gauze 25 are folded over as indicated by dotted lines 26 and 27 to form the blank of Figure 6(b). An absorbent pad 28, formed of any suitable absorbent material, such as folded gauze, non-woven fabrics, absorbent papers, etc., is then placed on the blank 6(b) between the folded edges 23 and 24. The absorbent pad 28 is substantially narrower than the folded gauze sheet. 25. An X-ray opaque strip '29 is then laid on top of the pad 28 to form the assembly of Figure 6(a). The assembly of Figure 6(c) is folded over on itself along dotted line 28 with the gauge 25 on the outside into the form illustrated in Figure 6(d). If it is desired to have the strip of X-ray opaquematerial extend along the legs of the U, as illustrated in Figure 2, the X-ray opaque strip would be laid across the blank of Figure 6(c), the ends extending beyond the edges of the blank where it was desired to use the ends of the X- ray opaque strip to secure the ends' of' the sponge together. However, the preferred manner of inserting the X-ray opaque member is that illustrated in Figure 6(a).
' The folded blank 6(d) is then rolled, starting from the edge opposite the fold 31, into the form illustrated in Figure 6(f). In forming the roll of Figure 6(f), care should be taken to first roll in the corners 32 and 33 as illustrated in Figure 6(2). It will be noted that the'resulting roll, illustrated in Figure'6(f), has all edges of the gauze fabric folded within the roll. This avoids any possibility of loose threads. The roll of Figure 60) is then bent in the center into a U shape and the ends 34 and 35 secured together to form the completed sponge as illustrated in Figure 6(g). In the preferred modification, particularly for the absorbent type of sponge, the ends of the X-ray opaque material terminate within the roll and the ends of the U are held together both by cementing and'by tying the ends 34 and 35, as by wrapping with thread 36. The tie, combined with the cement, is preferred particularly where a soft sponge. is desired since in such cases a relatively soft cement is used. The cement, as previously stated with reference to Figure 2(d), should cover the tying threads so that the same cannot become detached during use of the sponge.
Where it is desired that the sponge have a highly absorbent character and be soft and pliable, the absorbent filling 26 is preferably made of relatively bulky absorbent materials, such as non-woven fabrics, cotton, cellulose wadding or macerated wood pulp, and the folded blank of Figure 6(d) loosely rolled. Also, the X-ray detectable material should preferably be in 'the form of a thread.
Where it is desired that the sponge have a compact, relatively hard structure, the filler 26 is preferably made of several folds of gauze and the blank of Figure 6(d) is tightly rolled. Also, the X-ray detectable element is in strip form. In this form it adds substantially to the compactness and relative hardness of the sponge. Where the X-ray opaque material is used in this manner to increase the compactness of the sponge body, the ends will, of course, not protrude nor will the X-ray opaque material be parallel to the length of the roll.
The sponge structures of the present invention are simple to manufacture and permit a wide degree of variation with respect to absorbency and compactness. They also can be made in varying sizes. Although applicants, in their specification, have described their preferred embodiment of the invention and several modifications thereof, further modifications will, of course, be apparent to one skilled in the art after reading the specification. The invention includes all such modifications and is to be limited only by the appended claims.
