Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a small pad for use in, for example, brain surgery or orthopedic surgery, which can be found in the body by X-ray imaging or the like.
[0002]
[Prior art]
In surgical operations, many gauze and small surgical pads are used for the purpose of absorbing bleeding, protecting the tissue surface around the surgical site, and as a filter at the tip of the suction tube when sucking blood or the like. In particular, in the case of performing an operation on a fine part such as a brain surgery or an orthopedic surgery, a small surgical pad is exclusively used.
[0003]
If such a small surgical pad remains in the body, it may cause damage by pressing the brain, etc., and may cause various physical problems such as pain, discomfort, or slight fever. At that time, it is necessary to remove all small pads from the body.
[0004]
In particular, since the small pad is small (for example, 7 mm × 7 mm, 10 mm × 10 mm, 20 mm × 20 mm, 30 mm × 60 mm, etc.), there is a concern that it cannot be completely removed. Therefore, a technique is adopted in which a thread is sewn to the small pad (this thread may be referred to as a drawn thread in the present specification), and the other end of the drawn thread is extended outside the body for a mark. Yes.
[0005]
On the other hand, if the pad portion of the small surgical pad is made of gauze or absorbent cotton, lint etc. easily fall off from the cut end, and it is not good that this lint etc. remains in the body. A pad section has been proposed. That is, a large number of nonwoven fabrics laminated and entangled in the thickness direction (hereinafter sometimes referred to as laminated nonwoven fabrics), and a nonwoven fabric laminated on the front and back surfaces of the gauze and entangled in the thickness direction (hereinafter referred to as the following) It may be referred to as a nonwoven fabric laminated gauze). Since the laminated nonwoven fabric is a nonwoven fabric, the cut ends are rarely broken and yarn waste is hardly generated, and the nonwoven fabric laminated gauze is hardly unwound at the end of the nonwoven fabric layer. It also prevents the gauze from dissolving. Furthermore, although there is a concern that the strength is insufficient when the nonwoven fabric is thin, the nonwoven fabric laminated gauze has an excellent characteristic that a sufficient strength can be secured by the gauze of the intermediate layer.
[0006]
FIG. 2 is a perspective view showing a conventional small surgical pad 60. The small surgical pad 60 is composed of an absorbent pad portion 61 made of non-woven fabric and a cotton drawn yarn 62, and the pad portion 61 is zigzag-sewn by one end portion of the drawn yarn 62 (zigzag stitched portion). 62a), a drawn-out thread 62 is attached to the pad portion 61. The zigzag stitching portion 62a also serves to stop the nonwoven fabrics of the pad portion 61 from falling apart.
[0007]
[Problems to be solved by the invention]
As described above, the conventional small surgical pad is marked by the sewn thread, but the concern that the small pad remains in the body has not been completely wiped out, so it can be removed more reliably. Is desired.
[0008]
Therefore, the present inventor attaches an X-ray impermeable thread to the pad portion of the small surgical pad, performs X-ray contrast (X-ray imaging) before closing the surgical site at the end of the operation, and performs the X-ray impermeable operation. Using the thread as a clue, I came up with a method of checking for the presence of a small pad and removing it if it remained. As the X-ray impermeable yarn, a polypropylene resin filament kneaded with barium sulfate or a vinyl chloride resin or silicon resin filament kneaded with barium sulfate is generally used. Using the property of the heat-fusible resin used for the radiopaque yarn, a method of attaching the radiopaque yarn to the surface of the pad portion by thermal fusion was considered.
[0009]
However, the X-ray-impermeable yarns once fused and solidified tend to be hard, and especially when microstimulation is also a problem, as in brain surgery, heat fusion is likely to produce a hard mass. It is better to avoid wearing by wearing.
[0010]
Accordingly, an object of the present invention is to provide a small surgical pad that can be removed from a surgical field more reliably while maintaining flexibility while using an X-ray impermeable thread.
[0011]
[Means for Solving the Problems]
The small surgical pad according to the present invention is a small surgical pad in which a drawn yarn is attached to an absorbent pad portion having a plurality of laminated structures, and an X-ray impermeable substance-containing yarn (between layers of the absorbent pad portion ( The gist of the present invention is that it is sandwiched between X-ray non-transparent yarns hereinafter.
[0012]
Since the X-ray impermeable yarn is sandwiched between the layers of the pad portion of the laminated structure in this way, the X-ray impermeable yarn can be attached to the absorbent pad portion without melting and solidifying. The non-permeable yarn remains flexible and therefore retains the flexibility of the entire surgical pad. And it is good to confirm the presence or absence of a small pad by performing X-ray contrast as described above and using this X-ray impermeable thread as a clue.
[0013]
In addition to the above-mentioned barium sulfate, examples of the X-ray non-transparent material include silver sulfate, titanium oxide, silicon, and the like. This X-ray non-transparent material is contained in a resin such as polypropylene, polyethylene terephthalate, and vinyl chloride. It is better to use a thread.
[0014]
Furthermore, in the small surgical pad according to the present invention, it is preferable that the drawn thread is sewn across the X-ray impermeable substance-containing thread. Note that “the drawn yarn is sewn across the X-ray impermeable thread” includes not only the case of straddling the entire X-ray impermeable thread but also the case of striding a part of the X-ray impermeable thread. . It is more preferable to sew the whole X-ray impermeable thread with the drawn thread.
[0015]
Since the X-ray impermeable yarn is generally a filament mainly composed of a synthetic resin as described above, the surface thereof is smooth and slippery, the absorbent pad portion is small, and the portion of the X-ray impermeable yarn to be sandwiched is also short. Therefore, there is some concern that the X-ray impermeable thread slips through the pinch. However, by sewing with the drawn-out thread so as to straddle the X-ray impermeable thread as described above, the X-ray impermeable thread can be firmly fixed to the pad portion and will not easily fall off. In addition, since it is not attached by heat fusion, the X-ray impermeable thread can maintain flexibility, and the entire surgical small pad can also maintain flexibility.
[0016]
As the X-ray impermeable thread, if a very thin thread is difficult to find in X-ray contrast, it is preferable to use a thick thread, but when sewing such a thick thread to the absorbent pad portion, It is not always necessary that the first seam crosses over the entire diameter direction of the thick thread. Even if it is sewn so as to penetrate the X-ray non-transparent thread, that is, even if it is sewed over a part of the X-ray non-transmissible thread good. Examples of the sewing method include zigzag sewing using a sewing machine.
[0017]
In the present invention, the X-ray non-transparent substance-containing yarn is preferably a non-twisted multifilament.
[0018]
Non-twisted multifilaments are excellent in flexibility, and are preferable compared to monofilaments and twisted yarns having the same thickness, that is, the same degree of visibility during X-ray imaging.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1A is a perspective view showing a small surgical pad according to an embodiment of the present invention, and FIG. 1B is a cross-sectional view taken along line B-B shown in FIG.
[0020]
The small surgical pad 10 comprises an absorbent pad portion 11 and a cotton drawn yarn 12. The absorbent pad portion 11 has an X-ray impermeable yarn 18 placed on two cellulose nonwoven fabrics 13 and 14, and A cupra cotton 15 is laminated, a cellulose nonwoven fabric 16 is further laminated, and this is entangled and integrated in the thickness direction (FIG. 1B). The X-ray impermeable yarn 18 is a multifilament made of polypropylene in which barium sulfate is kneaded and arranged without twisting.
[0021]
The drawn yarn 12 is zigzag-sewn so as to straddle the X-ray impermeable yarn 18 at one end portion thereof (zigzag stitching portion 12a), and is sewn to the pad portion 11.
[0022]
Since the X-ray impermeable thread 18 is pressed against the pad portion 11 by the zigzag stitching portion 12a of the drawn thread 12 in this way, the X-ray impermeable thread 18 is firmly fixed and hardly comes off. .
[0023]
In addition, the X-ray non-transparent yarn 18 is flexible because it is a non-twisted multifilament, and the X-ray non-transparent yarn 18 is not fused so that it remains flexible. Therefore, the entire small surgical pad 10 is also flexible, and there is little risk of damaging the tissue during surgery.
[0024]
As described above, the small surgical pad according to the present invention has been specifically described with reference to the drawings showing examples. However, the present invention is not limited to the illustrated examples but can be adapted to the above-described purpose. It is also possible to carry out by appropriately changing the range, and all of them are included in the technical scope of the present invention.
[0025]
For example, although the nonwoven fabric or cotton laminated as the pad portion is mentioned, the present invention is not limited to this, and a nonwoven fabric laminated on gauze and an X-ray impermeable thread sandwiched between the layers may be used. . In the above example, the case of a pad portion having a four-layer structure is shown, but it is of course possible to have a two-layer, three-layer, or five-layer or six-layer structure.
[0026]
Further, in the above example, the drawn thread 12 is sewn so as to straddle the X-ray impermeable thread 18. However, the present invention is not limited to this, and the pad thread 11 does not have the X-ray impermeable thread 18. The drawn thread 12 may be sewn. In the above example, the X-ray impermeable thread 18 is arranged along the moving direction of the zigzag stitched portion 12a of the drawn thread 12. However, the present invention is not limited to this, for example, the moving direction of the zigzag stitched portion 12a The X-ray non-transparent yarn 18 may be arranged orthogonally, and the X-ray non-transparent yarn is transmitted to the pad portion 11 by crossing the X-ray non-transparent yarn 18 existing portion and the zigzag stitching portion 12a. The sex thread 18 can be sewn firmly.
[0027]
【The invention's effect】
The small surgical pad according to the present invention is provided with a non-radiation-impervious substance-containing yarn and has good flexibility, so that there is little fear of damaging the tissue in the surgical field. A small surgical pad can be found by X-ray contrast using the X-ray impermeable substance-containing yarn as a mark.
