Description

本発明は、眼科での手術等に際して用いられる眼科手術用覆布に関するものである。   The present invention relates to an ophthalmic surgical covering used for ophthalmic surgery and the like.

外科手術に際しては、手術野を無菌状態に保つ目的で手術野以外の身体表面をドレープで覆うことが一般に行われており、例えば白内障治療手術の様な眼の手術を行うにあたっては、手術野に対応した位置を開孔した眼科手術用覆布(例えば90cm×90cmや120cm×120cmの不織布)が用いられている。この覆布を使用するにあたっては、一般に手術台に仰臥した患者の眼の部分に覆布の開孔を合わせ、開孔の周縁に貼着された両面粘着テープで眼の回りに貼り付けて固定する。   During surgery, it is common practice to cover the body surface other than the surgical field with drape for the purpose of keeping the surgical field sterile. For example, when performing eye surgery such as cataract treatment surgery, An ophthalmic surgical covering (for example, a 90 cm × 90 cm or 120 cm × 120 cm non-woven fabric) having a corresponding hole opened is used. When using this covering cloth, generally align the opening of the covering cloth with the eye part of the patient who is supine on the operating table, and fix it by sticking around the eye with a double-sided adhesive tape attached to the periphery of the opening. To do.

ところで眼の周りは、鼻や額,こめかみ,ほお骨と連続した複雑な凹凸を有しているので、上記の様に両面粘着テープで貼り付けたつもりであっても、覆布の復元力によって凹部分が持ち上がり、手術中に剥がれてしまうことがある。そしてこの様にしてテープ面の貼り付け部に所々隙間ができると、この隙間から手術の際の洗浄液や血液等が覆布の内側(肌側)に漏れてしまうことがある。   By the way, the eyes have complex indentations that are continuous with the nose, forehead, temples, and cheekbones. The part may lift and peel off during surgery. If there are gaps in the tape-applied portion in this way, the cleaning liquid or blood during the operation may leak from the gap to the inside (skin side) of the covering cloth.

従って上記両面粘着テープとしては皮膚に強力に付着できるものが望ましいものの、あまりに強力な粘着テープであると、手術後に覆布を取り除くときに患者に苦痛を与えたり、また皮膚表面を剥がす等の損傷を与えたりするおそれがある。殊に老人の場合では皮膚が脆弱になっているので、接着力が強すぎることは問題である。   Therefore, it is desirable that the double-sided adhesive tape adheres strongly to the skin. However, if the adhesive tape is too strong, it may cause damage to the patient when the cover is removed after surgery, or the skin surface may be peeled off. There is a risk of giving. Especially in the case of elderly people, the skin is fragile, and it is a problem that the adhesive strength is too strong.

また患者によって皮膚の状態は様々で、ある患者では両面粘着テープが皮膚に付着し難く、貼付箇所に隙間を生じてしまうのに対し、他の患者では同様の粘着テープを用いても強く付着し過ぎて剥がす際に皮膚を傷つける場合もある。   The skin condition varies from patient to patient. In some patients, double-sided adhesive tapes are difficult to adhere to the skin, and gaps are created at other locations, while other patients adhere strongly even when similar adhesive tapes are used. In some cases, the skin may be damaged when it is peeled off.

そこで上記の問題を解消したものとして、覆布の手術野開孔の周縁部裏面側に肉厚のゲル状粘着剤層を設けた眼科手術用覆布が提案されている(特許文献1参照)。この覆布では、上記肉厚のゲル状粘着剤層が伸縮することによって覆布の復元力が吸収されるから、手術中に容易に剥がれない。またこの様に容易に剥がれないから、ゲル状粘着剤層として比較的粘着力の低い材料を用いることができ、手術後に剥離する際に皮膚を殆ど傷つけないという効果を奏する。
特開2003−325544号公報
Therefore, as a solution to the above problem, an ophthalmic surgical covering cloth in which a thick gel-like adhesive layer is provided on the back side of the peripheral edge of the surgical field opening of the covering cloth has been proposed (see Patent Document 1). . In this covering cloth, since the restoring force of the covering cloth is absorbed by the expansion and contraction of the thick gel-like pressure-sensitive adhesive layer, it is not easily peeled off during the operation. Moreover, since it does not peel off easily as described above, a material having a relatively low adhesive strength can be used as the gel-like pressure-sensitive adhesive layer, and there is an effect that the skin is hardly damaged when peeling off after the operation.
JP 2003-325544 A

上記の如く特許文献1の覆布によれば、開孔の周縁にぴったりと貼り付けることができるものであるが、貼着箇所からの洗浄液等の肌側への漏れの原因は、上述した覆布の復元力による凹部分の持ち上がりだけではなく、貼着操作時の貼り付け不良による場合もある。つまり上記の如く眼の周りは複雑な凹凸を呈しているので、貼付に際して覆布がシワになり易く、従って丁寧に貼り付けないと、隙間を生じたままとなるのである。   As described above, according to the covering cloth of Patent Document 1, it can be attached to the periphery of the opening exactly. However, the cause of leakage of the cleaning liquid or the like from the attaching portion to the skin side is the above-described covering. In addition to the lifting of the concave portion due to the restoring force of the cloth, it may be due to a sticking failure during the sticking operation. That is, as described above, since the eye has complicated irregularities, the covering cloth is likely to be wrinkled at the time of application, and therefore a gap is left if not applied carefully.

そこで本発明の目的は、開孔周囲において隙間を生じさせずに貼り付けるという操作を容易に行うことのできる眼科手術用覆布を提供することにある。   Accordingly, an object of the present invention is to provide an ophthalmic surgical covering cloth that can be easily attached without causing a gap around the opening.

本発明に係る眼科手術用覆布は、眼科手術野に対応した開孔を備え、該開孔の周縁部を皮膚に貼り付けて用いる眼科手術用覆布であって、少なくとも前記周縁部がポリウレタンフィルムにより構成され、該ポリウレタンフィルムの皮膚側面に粘着剤層が設けられたものであることを特徴とする。尚本明細書及び特許請求の範囲において、フィルムと称した場合にはシートが含まれ、シートと称した場合にはフィルムが含まれる。   An ophthalmic surgical covering according to the present invention is an ophthalmic surgical covering provided with an opening corresponding to an ophthalmic surgical field, and the peripheral edge of the opening is attached to the skin, and at least the peripheral edge is polyurethane. It is comprised by the film, The adhesive layer was provided in the skin side surface of this polyurethane film, It is characterized by the above-mentioned. In the present specification and claims, a sheet is included when referred to as a film, and a film is included when referred to as a sheet.

従来では専ら覆布に用いる布やシートに孔を開けただけであり、開孔の周縁部についても覆布の他の部分と同じ素材であって、伸び難いものである為に、眼の周りの凹凸に追従し難く、皺になり易かった。しかし本発明では上述の様に、開孔周縁部にポリウレタンフィルムを用いており、このポリウレタンフィルムは柔軟性に富み良く伸びる素材であるから、眼の周りの様な凹凸のある箇所に貼り付けるに際して、該凹凸に沿って伸ばしながら貼り付けることができ、従って皺が寄り難く、容易に隙間を生じさせずに貼付することができる。尚、皮膚への貼着はポリウレタンフィルムの皮膚側面に設けられた上記粘着剤層によって成される。   In the past, only holes or holes were made in the cloth or sheet used for the covering cloth, and the periphery of the opening was the same material as the other parts of the covering cloth and was difficult to stretch. It was difficult to follow the unevenness of the and it was easy to become a habit. However, in the present invention, as described above, a polyurethane film is used at the peripheral edge of the aperture, and since this polyurethane film is a material that is flexible and stretches well, it is necessary to apply it to uneven portions such as around the eyes. It can be applied while extending along the unevenness, so that the wrinkles are not easily moved and can be easily applied without generating a gap. In addition, the sticking to the skin is made by the pressure-sensitive adhesive layer provided on the skin side surface of the polyurethane film.

また上記の通りポリウレタンフィルムは良く伸びる素材であり、復元力による凹部分の持ち上がりの力も小さいから、持ち上がって浮くということも起き難い。   Further, as described above, the polyurethane film is a material that stretches well, and since the lifting force due to the restoring force is small, it is difficult for the polyurethane film to lift and float.

加えてポリウレタンフィルムは伸縮性が良好であり、一旦貼った後に外したとき、初めに貼った際に伸びた箇所が縮んで元に戻るので、再び貼り直すことができる。つまり例えばポリオレフィンフィルムの場合には、一旦伸びると、伸びたままで縮まないから、これの貼り直しを行うとすると、その伸びた箇所が皺になる虞がある。これに対して上述の様にポリウレタンフィルムであれば、皺を生じさせずに貼り直すことができる。   In addition, the polyurethane film has good stretchability, and when it is removed after being pasted, the stretched portion contracts when it is first pasted and returns to its original state, so that it can be pasted again. That is, for example, in the case of a polyolefin film, once it is stretched, it remains stretched and does not shrink. Therefore, when the film is reapplied, the stretched portion may become wrinkles. On the other hand, if it is a polyurethane film as mentioned above, it can reapply, without producing a wrinkle.

斯様な前記ポリウレタンフィルムとしては、そのMD方向(フィルムの製造流れ方向)及びTD方向(MD方向と直交する方向)における100%伸び時の引張応力(JIS K 7311による)が8.0MPa以下、引張破断時伸び(JIS K 7311による)が500%以上であることが好ましい。   As such a polyurethane film, the tensile stress at 100% elongation (according to JIS K 7311) in the MD direction (the production flow direction of the film) and the TD direction (the direction perpendicular to the MD direction) is 8.0 MPa or less, It is preferable that the elongation at break (according to JIS K 7311) is 500% or more.

フィルムの引張応力が高すぎると、皮膚に貼付する際に力を要する上、瞼周辺の凹凸への追従性に乏しく、また引張破断時伸びが低すぎると、伸ばした際に破れる虞があるが、上記の様な引張応力及び引張破断時伸びを示すポリウレタンフィルムであれば、弱い力で良く伸びるので、皮膚への貼り付け操作を非常に容易に行えると共に、凹凸への追従性が良好であり、また十分な強度を備える。尚、100%伸び時の引張応力とは、試験片に100%の伸びを与えたときの応力であり、引張破断時伸びとは、試験片を引っ張って破断した時の標線間距離を測定したときの伸び率である。   If the tensile stress of the film is too high, it will require force when affixing to the skin, and it will have poor ability to follow the irregularities around the heel, and if the elongation at break is too low, it may break when stretched. If it is a polyurethane film that exhibits tensile stress and elongation at break as described above, it will stretch well with a weak force, so that it can be applied to the skin very easily and has good conformity to irregularities. And with sufficient strength. The tensile stress at 100% elongation is the stress when 100% elongation is given to the test piece, and the tensile elongation at break is the distance between the marked lines when the test piece is pulled and broken. It is the rate of elongation when

また上記ポリウレタンフィルムにおける引張強さ(JIS K7311による)が50MPa以上であることが好ましい。50MPa以上であれば、貼付操作中等においてポリウレタンフィルムが破ける心配が殆どないからである。   The tensile strength (according to JIS K7311) of the polyurethane film is preferably 50 MPa or more. This is because if it is 50 MPa or more, there is almost no fear that the polyurethane film will be broken during the sticking operation or the like.

前記粘着剤層としては、患者の皮膚に対して刺激が少なく、瞼周辺の凹凸形状や皺に対して柔軟に追従できるものが望ましい。そして粘着剤層の粘着力としては高い方が剥がれ難いことから好ましいのであるが、粘着力が高すぎると、手術後に皮膚から剥がす際に皮膚を痛める懸念があるので、あまり強いものを用いることができない。この点において本発明の如くポリウレタンフィルムに設ける場合であれば、上述の様にフィルムが良く伸びて凹部分が持ち上がって浮くということが生じ難いので、粘着剤層として、比較的粘着力の低い素材のもの(例えば180度引きはがし粘着力が0.9〜2.5N/25mm(測定法:JIS Z 0237、試験板;ベークライトパネル))を採用しても、十分な粘着力(剥離強度)が確保されて手術中に容易に剥離することがない。よって比較的皮膚の弱い患者に適応させた弱い粘着力の粘着剤層を用いることが可能となって、手術終了後の覆布剥離時における皮膚の損傷をかなり防ぐことができる。   The pressure-sensitive adhesive layer is preferably one that has little irritation to the patient's skin and can flexibly follow the uneven shape around the heel and the heel. And as the adhesive strength of the pressure-sensitive adhesive layer is high, it is preferable because it is difficult to peel off, but if the adhesive strength is too high, there is a concern that it may damage the skin when peeling from the skin after surgery, so use a strong one Can not. In this respect, if it is provided on a polyurethane film as in the present invention, it is difficult to cause the film to stretch well and the concave portion is lifted and floated as described above. Adhesive strength (peeling strength) can be obtained even if one is used (for example, 180-degree peeling adhesive strength is 0.9 to 2.5 N / 25 mm (measurement method: JIS Z 0237, test plate; bakelite panel)) Secured and not easily peeled off during surgery. Therefore, it is possible to use an adhesive layer having a weak adhesive force adapted to a patient with relatively weak skin, and skin damage at the time of peeling the covering after the operation can be considerably prevented.

斯様な前記粘着剤層の粘着力(JIS Z 0237 180度引きはがし粘着力の測定法による)としては、0.9〜2.5N/25mmであることが好ましい。ポリウレタンフィルムに設ける粘着剤層として上記粘着力のものを用いれば、手術中に容易に外れることがなく、また剥がす際に殆ど皮膚を痛めない。   The pressure-sensitive adhesive strength of the pressure-sensitive adhesive layer (according to JIS Z 0237 180-degree peeling pressure measurement method) is preferably 0.9 to 2.5 N / 25 mm. If an adhesive layer having the above adhesive strength is used as a pressure-sensitive adhesive layer provided on a polyurethane film, it does not easily come off during surgery, and hardly hurts the skin when peeled off.

また前記粘着剤層の保持力(JIS Z 0237による(ずれ長さ)(貼付面積12mm×20mm、荷重200gで30分間放置))としては、0.1〜0.5mmであることが好ましい。この程度の保持力を有していれば、一旦瞼周辺に貼着したポリウレタンフィルムが、手術中にずれるということが殆どない。   Further, the holding force of the pressure-sensitive adhesive layer ((shift length) according to JIS Z 0237 (attached area 12 mm × 20 mm, left at a load of 200 g for 30 minutes)) is preferably 0.1 to 0.5 mm. If it has this level of holding power, the polyurethane film once attached to the periphery of the heel rarely shifts during the operation.

粘着剤層の厚みとしては20〜50μmが好ましい。この厚みであれば貼着力が十分に確保され、また手術後に覆布を取り外すにあたって、投錨破壊に起因する皮膚への粘着剤残りが生じ難い。このうち特に30μm±10%程度が推奨される。   The thickness of the pressure-sensitive adhesive layer is preferably 20 to 50 μm. If it is this thickness, adhesive force is fully ensured, and when removing a cover cloth after an operation, it is hard to produce the adhesive residue to the skin resulting from throwing destruction. Of these, about 30 μm ± 10% is recommended.

更に本発明に係る眼科手術用覆布においては、前記ポリウレタンフィルムが透明ないし半透明であることが好ましい。覆布の開孔周縁部を皮膚に貼り付けるにあたって、従来では皮膚への貼着状態が分からないことから、浮き等の隙間を生じたままにしてしまい、この隙間から手術の際の洗浄液等が患者側(裏側)に漏れるということがあったが、上記の如くポリウレタンフィルムが透明ないし半透明であれば、粘着剤層による皮膚への貼着状態を表側(反皮膚側)から容易に目視により確認することができ、従って隙間を生じている箇所を見つけた場合には、ここを押す等してしっかりと貼り付けて塞ぐことが可能となる。   Furthermore, in the ophthalmic surgical covering according to the present invention, the polyurethane film is preferably transparent or translucent. When pasting the peripheral edge of the opening of the cover cloth to the skin, the state of sticking to the skin is not known in the past, so a gap such as a float is left, and from this gap the cleaning liquid at the time of surgery etc. When the polyurethane film is transparent or translucent as described above, the adhesive state of the adhesive layer on the skin can be easily visually checked from the front side (anti-skin side). Therefore, when a portion where a gap is generated is found, it is possible to close it by firmly sticking it by pressing it.

この様なポリウレタンフィルムとしては、全光線透過率(JIS K 7105による)が60〜80%で、この全透過光線に占める拡散透過光率(ヘーズ値)(JIS K 7105による)が60〜85%であることが好ましい。全光線透過率が60〜80%であれば、表側(反皮膚側)からフィルムを通して貼着状態を十分に確認できる程度に透明感があるからである。またヘーズ値が60〜85%であれば、ポリウレタンフィルムがくすむ様になって目立たず、これと相対して手術野の視認性を向上させることが期待できるからである。   As such a polyurethane film, the total light transmittance (according to JIS K 7105) is 60 to 80%, and the diffuse transmittance (haze value) in the total transmitted light (according to JIS K 7105) is 60 to 85%. It is preferable that This is because if the total light transmittance is 60 to 80%, there is a transparency to the extent that the sticking state can be sufficiently confirmed through the film from the front side (anti-skin side). Further, if the haze value is 60 to 85%, the polyurethane film becomes dull and unnoticeable, and it can be expected to improve the visibility of the surgical field in contrast to this.

加えてポリウレタンフィルムの反皮膚側面の表面グロスとしては20%前後であることが好ましい。20%前後であれば、表面の光沢があまりなく、従って貼着状態を確認し易くなるからである。   In addition, the surface gloss of the anti-skin side surface of the polyurethane film is preferably around 20%. If it is around 20%, there is not much gloss on the surface, so it is easy to confirm the state of sticking.

またポリウレタンフィルムの厚みとしては、0.04〜0.1mmのものが推奨される。厚みが薄い程、より細かな凹凸に対する追従性が増すことから好ましいものの、十分な強度を確保する観点からは厚い方が良い。これらの観点から上記の如く厚み範囲が望ましい。   The thickness of the polyurethane film is recommended to be 0.04 to 0.1 mm. The thinner the thickness, the better the followability to finer irregularities, but the thicker the better, from the viewpoint of ensuring sufficient strength. From these viewpoints, the thickness range is desirable as described above.

本発明に係る眼科手術用覆布によれば、該覆布の開孔周縁部を皮膚に貼り付けるに際し、シワ等の隙間を生じさせずに貼付することが容易に行え、従って作業者の手間が軽減され、加えて隙間なく貼れることで、患者側(覆布裏側)に手術中の洗浄液等が漏れることを防止することができる。   According to the covering cloth for ophthalmic surgery according to the present invention, when the peripheral edge portion of the opening of the covering cloth is attached to the skin, it can be easily attached without generating a gap such as wrinkles, and therefore, it is troublesome for the operator. In addition, since it can be applied without any gaps, it is possible to prevent leakage of cleaning fluid or the like during surgery on the patient side (back side of the covering cloth).

FIG. 1 is a view (front view) of a cover 20 for ophthalmic surgery according to Embodiment 1 of the present invention as viewed from the front side (anti-skin side), and FIG. 2 is a cross-sectional view taken along line AA shown in FIG. .

この覆布20は、患者を大きく覆う覆布本体21と、手術野開孔周囲の開孔周縁部17から構成され、該周縁部17の皮膚側全面に粘着剤層19が設けられた構造となっている。覆布本体21は撥水性のポリエステル(或いはポリプロピレン)製不織布からなり、周縁部17は伸縮性,柔軟性に優れたポリウレタンフィルムからなり、粘着剤層19はアクリル系樹脂から構成されている。   This covering cloth 20 is composed of a covering cloth main body 21 that largely covers a patient and an opening peripheral edge 17 around the surgical field opening, and a structure in which an adhesive layer 19 is provided on the entire skin side of the peripheral edge 17. It has become. The covering cloth body 21 is made of a water-repellent polyester (or polypropylene) non-woven fabric, the peripheral edge portion 17 is made of a polyurethane film excellent in stretchability and flexibility, and the adhesive layer 19 is made of an acrylic resin.

開孔周縁部17には眼科手術野に対応して開孔62が設けられ(図中、17aは周縁部17の開孔縁を示す)、覆布本体21にはこの開孔62よりも大きく且つ周縁部17の外縁サイズ(図中、17bは周縁部17の外縁を示す)よりも小さい開孔が設けられており(図中、21aは覆布本体21の開孔縁を示す)、図1、2に示す様に、この覆布本体21の開孔内(開孔縁21aの内側)のほぼ中央に周縁部17の開孔62が位置する様に配置されている。そしてこれら周縁部17と覆布本体21は上記粘着剤層19によって貼り付けられている。   An opening 62 is provided in the opening peripheral edge portion 17 corresponding to the ophthalmic surgical field (in the figure, 17a indicates an opening edge of the peripheral edge portion 17), and the covering cloth main body 21 is larger than the opening 62. In addition, an opening smaller than the outer edge size of the peripheral edge portion 17 (in the drawing, 17b indicates the outer edge of the peripheral edge portion 17) is provided (in the drawing, 21a indicates the opening edge of the covering cloth body 21). As shown in FIGS. 1 and 2, the opening 62 of the peripheral edge portion 17 is arranged at the approximate center in the opening of the covering cloth body 21 (inside the opening edge 21 a). And these peripheral edge part 17 and the covering fabric main body 21 are affixed by the said adhesive layer 19. FIG.

覆布本体21の開孔内(開孔縁21aの内側)に露出する粘着剤層19の幅、つまり周縁部17の開孔縁17aから覆布本体21の開孔縁21aの幅(B1、B2、…)は大凡10〜30mmであり、覆布20を手術野開孔62周縁に貼り付けるにあたって適度な大きさである。尚、製品の保管時(或いは運搬時)等においては、粘着剤層19の露出面を覆う様にしてその皮膚側面に離型紙18が貼付されている(図1,2に仮想線(二点鎖線)で示す)。 The width of the adhesive layer 19 exposed in the opening of the covering cloth body 21 (inside the opening edge 21a), that is, the width of the opening edge 21a of the covering cloth body 21 from the opening edge 17a of the peripheral edge portion 17 (B 1 , B 2 ,...) Is approximately 10 to 30 mm, which is an appropriate size for attaching the covering cloth 20 to the periphery of the surgical field opening 62. When the product is stored (or transported) or the like, a release paper 18 is affixed to the side of the skin so as to cover the exposed surface of the adhesive layer 19 (virtual lines (two points in FIGS. 1 and 2). Indicated by chain line)).

次に本実施形態1の覆布20の折り畳み方について説明する。   Next, how to fold the cover cloth 20 of the first embodiment will be described.

図3の(a)〜(c),図4の(a)〜(d)及び図5の(a)〜(g)は覆布20の折り畳み手順を表す正面図であって、覆布20の表側(反皮膚側)から見た図である(分かり易くする為、図3,4ではほんの少しだけ斜め方向から画いている)。尚離型紙18は使用直前に剥離するものであるから、製品としては離型紙18が付いたものとなっている(尚便宜上、離型紙18の取り付けられたものも覆布20と称することがある)。   FIGS. 3A to 3C, FIGS. 4A to 4D, and FIGS. 5A to 5G are front views showing a folding procedure of the cover cloth 20. FIG. 3 is a view seen from the front side (anti-skin side) of FIG. Since the release paper 18 is peeled off immediately before use, the product is provided with the release paper 18 (for convenience, the paper attached with the release paper 18 may also be referred to as a cover cloth 20). ).

先ず図3(a)に示す様に、覆布20の四辺のうちの一辺21b1を持ち、この辺21b1が周縁部17を覆う程度の深さとなる様にして折り畳む(矢印C)。尚このとき表側(反皮膚側)が折り畳みの内側となる。続いてこの折り畳み縁C1を持ち、折り畳み縁C1が本体開孔縁21aよりもやや外側の位置となる様に内側に折り畳む(図3(b)、矢印D)。次いで覆布20の上記辺21b1を持ち、上記折り畳み縁C1に沿う様にして外側に折り畳む(図3(c)、矢印E)。 First, as shown in FIG. 3 (a), has one side 21b 1 of the four sides of the drapes 20, the edges 21b 1 is folded in the manner a deep enough to cover the peripheral portion 17 (arrow C). At this time, the front side (the anti-skin side) is the inside of the folding. Subsequently, the folding edge C 1 is held, and the folding edge C 1 is folded inward so that the folding edge C 1 is located slightly outside the main body opening edge 21a (FIG. 3B, arrow D). Next, the cover cloth 20 has the side 21b 1 and is folded outward along the folding edge C 1 (FIG. 3 (c), arrow E).

次に上記と同様に、辺21b1と対向する辺21b2を持ち、この辺21b2が周縁部17を覆う程度の深さとなる様にして、表側(反皮膚側)を内側に折り畳む(図4(a)、矢印F)。続いてこの折り畳み縁F1を持ち、折り畳み縁F1が本体開孔縁21aよりもやや外側の位置となる様に内側に折り畳む(図4(b)、矢印G)。次いで覆布20の上記辺21b2を持ち、上記折り畳み縁F1に沿う様にして外側に折り畳む(図4(c)、矢印H)。 Next, similarly to the above, the side 21b 2 is opposed to the side 21b 1 and the front side (anti-skin side) is folded inward so that the side 21b 2 is deep enough to cover the peripheral edge 17 (FIG. 4). (A), arrow F). Subsequently, the folding edge F 1 is held, and the folding edge F 1 is folded inward so that the folding edge F 1 is positioned slightly outside the main body opening edge 21a (FIG. 4B, arrow G). Next, the cover cloth 20 has the side 21b 2 and is folded outward along the folding edge F 1 (FIG. 4C, arrow H).

次に、辺21b1と辺21b2の間の一方の辺21b3を持ち、この辺21b3が周縁部17を覆う程度の深さとなる様にして、表側(反皮膚側)を内側に折り畳む(図4(d)、矢印I)。続いてこの折り畳み縁I1を持ち、折り畳み縁I1が本体開孔縁21aよりもやや外側の位置となる様に内側に折り畳む(図5(a)、矢印J)。次いで覆布20の上記辺21b3を持ち、上記折り畳み縁I1に沿う様にして外側に折り畳む(図5(b)、矢印K)。 Next, one side 21b 3 between the side 21b 1 and the side 21b 2 is provided, and the front side (anti-skin side) is folded inward so that the side 21b 3 is deep enough to cover the peripheral edge 17 ( FIG. 4 (d), arrow I). Subsequently, the folding edge I 1 is held, and the folding edge I 1 is folded inward so that the folding edge I 1 is positioned slightly outside the main body opening edge 21a (FIG. 5A, arrow J). Next, the covering cloth 20 has the side 21b 3 and is folded outward along the folding edge I 1 (FIG. 5B, arrow K).

次に上記と同様に、辺21b3と対向する辺21b4を持ち、この辺21b4が周縁部17を覆う程度の深さとなる様にして、表側(反皮膚側)を内側に折り畳む(図5(c)、矢印L)。続いてこの折り畳み縁L1を持ち、折り畳み縁L1が本体開孔縁21aよりもやや外側の位置となる様に内側に折り畳む(図5(d)、矢印M)。次いで覆布20の上記辺21b4を持ち、上記折り畳み縁L1に沿う様にして外側に折り畳む(図5(e)、矢印N)。 Next, similarly to the above, the side 21b 4 is opposed to the side 21b 3, and the front side (anti-skin side) is folded inward so that the side 21b 4 is deep enough to cover the peripheral edge 17 (FIG. 5). (C), arrow L). Subsequently, the folding edge L 1 is held, and the folding edge L 1 is folded inward so that the folding edge L 1 is positioned slightly outside the main body opening edge 21a (FIG. 5 (d), arrow M). Next, the covering cloth 20 has the side 21b 4 and is folded outward along the folding edge L 1 (FIG. 5 (e), arrow N).

この様にして折り畳むと、図5(f)に示す様に本体開孔縁21aの内側における周縁部17の全てが視認できる状態となって現れる。尚、図示例の様に辺21b1と辺21b2が折り畳んだ外幅端よりも内側に位置しているのに対して、辺21b3及び辺21b4は折り畳んだ外幅端よりも外側(或いは折り畳んだ外幅端程度)に位置しているが、これは周縁部17が横長の長方形であったり、覆布本体21の大きさによるものである。 When folded in this manner, as shown in FIG. 5 (f), the entire peripheral edge portion 17 inside the main body opening edge 21a appears. Note that the side 21b 1 and the side 21b 2 are located on the inner side of the folded outer width end as in the illustrated example, whereas the side 21b 3 and the side 21b 4 are outside the folded outer width end ( Alternatively, the peripheral edge 17 is a horizontally long rectangle or is due to the size of the covering cloth main body 21.

その後、辺21b3側と辺21b4側とを合わせる様にして二つ折りにする(図5(f)、矢印O)。以上の様にして折り畳んだ状態の覆布製品が出来上がる(図5(g))。 After that, the side 21b 3 side and the side 21b 4 side are matched and folded in two (FIG. 5 (f), arrow O). The folded cloth product in the folded state is completed as described above (FIG. 5 (g)).

次にこの覆布20の使用方法について説明する。   Next, the usage method of this covering cloth 20 is demonstrated.

先ず図5(g)に示す覆布製品から離型紙18を外して周縁部17の粘着剤層19を露出させ、上記の二つ折りを解きつつ患者の手術野周辺(瞼周辺)に周縁部17を貼り付ける。   First, the release paper 18 is removed from the covering cloth product shown in FIG. 5 (g) to expose the adhesive layer 19 of the peripheral portion 17, and the peripheral portion 17 is provided around the patient's surgical field (periphery of the heel) while unfolding the above two folds. Paste.

このとき、図5(f)や図6[覆布20製品の使用方法を説明する為の正面図]の(a)に示す様に、覆布20は折り畳んだコンパクトな状態でありながらも、本体開孔縁21aの内側における周縁部17の全てが外側から見える。そして周縁部17は柔軟性に富み良く伸びるから、目の周りの凹凸に良好に追従させることができて、粘着剤層19によって皮膚に密着させて貼り付けることができ、しかもこの操作が容易である。詳しく述べると、上記の通り周縁部17のMD及びTD方向の伸びが大凡580%と大きいから、凹凸が激しい場合であっても伸ばして貼ることができて皺が寄り難く、加えて周縁部17のMD及びTD方向の10%伸び時の引張応力が2.4MPa程度、20%伸び時の引張応力が3.7MPa程度であって、大凡1.1N程の力で伸び、他方、瞼周りの凹凸に追従させるには大抵20%程度伸ばすだけで済むから、簡単に隙間を作らない様に貼り付けることができる。   At this time, as shown in FIG. 5 (f) and FIG. 6 (a front view for explaining how to use the covering cloth 20 product), the covering cloth 20 is in a folded and compact state, All of the peripheral edge 17 on the inner side of the main body opening edge 21a is visible from the outside. Since the peripheral edge portion 17 is rich in flexibility and can be extended well, it can follow the unevenness around the eyes well, and can be adhered and adhered to the skin by the adhesive layer 19, and this operation is easy. is there. More specifically, since the elongation in the MD and TD directions of the peripheral edge portion 17 is as large as about 580% as described above, it can be stretched and pasted even when the unevenness is severe, and the wrinkle is difficult to move. The tensile stress at 10% elongation in the MD and TD directions is about 2.4 MPa, the tensile stress at 20% elongation is about 3.7 MPa, and it grows with a force of about 1.1 N, while In order to follow the irregularities, it is usually only necessary to stretch about 20%, so it can be pasted so as not to make a gap easily.

更に周縁部17は半透明であるから貼着状態を表側(反皮膚側)から確認することができる。具体的には貼り付いた箇所と浮いた箇所では色が違って見える。そして浮いている箇所(皺や貼り付けムラ、浮き上がりによって隙間を生じている箇所)があれば、そこを押さえる等してしっかりと密着させることで、簡単に隙間のない様にできる。   Furthermore, since the peripheral edge part 17 is translucent, the state of attachment can be confirmed from the front side (anti-skin side). Specifically, the color looks different in the pasted and floating areas. And if there is a floating part (a part that has a gap due to wrinkles, sticking unevenness, or floating), it can be easily made free of gaps by pressing it firmly.

加えて貼り直したいときでも、コンパクトに折り畳まれた覆布20であるから、清潔且つ容易に貼り直しを行うことができる。つまり、一旦覆布を展開した後で貼り直す場合は、大きいことから操作し辛く、この為に覆布の様々な箇所を触って汚染する危険があるが、上記の様にコンパクトな状態であれば、汚染の事態を避けることが可能である。また上記の如くコンパクトであるから、一人で操作する場合にも簡単に行うことができる。加えて貼り付け自体の操作についても、周縁部17は復元性が良好であるから、一旦伸びた部分も元に戻り、皺となって残ることが殆どない。   In addition, even when it is desired to re-paste, since the cover cloth 20 is compactly folded, the re-paste can be performed cleanly and easily. In other words, once the cover cloth is unfolded and re-applied, it is difficult to operate because of its large size, and for this reason there is a risk of touching and contaminating various parts of the cover cloth. It is possible to avoid contamination. Further, since it is compact as described above, it can be easily performed even when it is operated alone. In addition, as for the operation of pasting itself, since the peripheral edge portion 17 has a good restoration property, the stretched portion returns to its original state and hardly remains as a wrinkle.

この様にして周縁部17を隙間のない様にして皮膚に貼り付けた後、辺21b3及び辺21b4付近(例えば図6(a)に示す星印の箇所)を掴み、外側にスライドさせて広げる(矢印P)。続いて辺21b1及び辺21b2付近(例えば図6(b)に示す星印の箇所)を掴み、外側にスライドさせて広げる(矢印Q)。 In this way, after the peripheral edge portion 17 is attached to the skin without a gap, the vicinity of the side 21b 3 and the side 21b 4 (for example, the star mark shown in FIG. 6A) is grasped and slid outward. (Arrow P). Subsequently, the vicinity of the side 21b 1 and the side 21b 2 (for example, the star mark shown in FIG. 6B) is grasped and slid outward to expand (arrow Q).

この様にして覆布20が広げられ(図1)、患者を覆布20で覆う操作が完了する。   In this way, the covering cloth 20 is spread (FIG. 1), and the operation of covering the patient with the covering cloth 20 is completed.

その後手術を行うが、このとき上記の様に瞼周りの開孔周縁部17はしっかりと密着する様に隙間なく貼り付けられているから、手術の際の洗浄液等は覆布20の裏側(皮膚側)に漏れることが回避される。   Thereafter, an operation is performed. At this time, the peripheral edge 17 of the opening around the heel is affixed without a gap so as to be tightly adhered. Side) is avoided.

<Embodiment 2>
FIG. 7 is a view of the ophthalmic surgical covering cloth 10 according to the second embodiment of the present invention as viewed from the front side (anti-skin side). The same components as those in FIGS. 1 and 2 are denoted by the same reference numerals to avoid redundant description.

この覆布10は受液ポケットタイプのものであり、全体の大きさは上記実施形態1のものよりも小さく、覆布本体11の目尻側の部分を折り返して両側縁12,13を接着することにより受液ポケット14を形成したものである。この覆布本体11はポリエチレン製シートでからなり、防水性を示す。ポケット14における反皮膚側のシートには、そのポケット入口14aと平行してその縁近傍に棒状の保形部材16が取り付けられている。この保形部材16は合成樹脂製の塑性変形可能なもの(例えば比較的硬質で変形可能なポリエチレン樹脂製帯状物)である。尚この保形部材16をその略中央部分を突き出す様に折り曲げることにより、ポケット入口14aが大きく開き、手術中の洗浄液等をポケット14内に良好に捕集できる(図8:実施形態2に係る眼科手術用覆布10についてポケット14を広く開けた状態を表す正面図)。実施形態2の覆布10におけるその他の構成は上記実施形態1と同様である。   The covering cloth 10 is of a liquid-receiving pocket type, the overall size is smaller than that of the first embodiment, and the side edges 12 and 13 are bonded by folding back the portion of the covering cloth body 11 on the outer corners. Thus, the liquid receiving pocket 14 is formed. This covering cloth main body 11 consists of a sheet | seat made from a polyethylene, and shows waterproofness. A rod-shaped shape retaining member 16 is attached to the sheet on the side opposite to the skin in the pocket 14 in the vicinity of the edge in parallel with the pocket inlet 14a. The shape-retaining member 16 is made of synthetic resin and can be plastically deformed (for example, a relatively hard and deformable polyethylene resin strip). In addition, by folding the shape-retaining member 16 so as to protrude the substantially central portion thereof, the pocket inlet 14a is greatly opened, and the cleaning liquid and the like during the operation can be collected well in the pocket 14 (FIG. 8: Embodiment 2) The front view showing the state which opened pocket 14 widely about covering cloth 10 for ophthalmic surgery). Other configurations of the cover cloth 10 of the second embodiment are the same as those of the first embodiment.

本実施形態2においても、周縁部17は柔軟性に富み良く伸びるから、目の周りの凹凸に追従し易く、容易に密着させて貼り付けることができる。また周縁部17は半透明であるから、貼着状態を確認しつつ貼れるので、貼り残しを防止できる。   Also in the second embodiment, since the peripheral edge portion 17 is rich in flexibility and extends well, it is easy to follow the irregularities around the eyes and can be easily adhered and pasted. Moreover, since the peripheral part 17 is translucent, since it can affix while confirming the sticking state, it can prevent a sticking remaining.

尚実施形態2の覆布10は、これ単独で用いても良いし、或いは例えば大判の覆布(手術野開孔を大きくしたもの)の反皮膚側面に重ねる様にして貼り付け、使用しても良い。   In addition, the covering cloth 10 of Embodiment 2 may be used alone or, for example, pasted and used so as to overlap the anti-skin side surface of a large covering cloth (with a larger surgical field opening). Also good.

The polyethylene sheet covering cloth main body 11 is pasted by a double-sided adhesive tape 39 in the vicinity of the main body opening edge 21a (they are overlapped so that each main body opening edge 21a just fits), and the peripheral part on the anti-skin side of the covering cloth body 11 17 (with the adhesive layer 19) is attached (FIG. 10).

本実施形態3の場合も、実施形態1で説明した様に折り畳んだものとすることが推奨される。この折り畳みに際しては、ポケットタイプ部分の覆布10を覆布本体21と一体的に取り扱うと良い。   In the case of the third embodiment, it is recommended that it is folded as described in the first embodiment. At the time of folding, the cover-type cloth 10 of the pocket type portion is preferably handled integrally with the cover-cloth main body 21.

本実施形態3においても、周縁部17は柔軟性に富み良く伸びるから、目の周りの凹凸に追従し易く、容易に密着させて貼り付けることができる。また周縁部17は半透明であるから、貼着状態を確認しつつ貼れるので、貼り残しが生じるのを防止できる。   Also in the third embodiment, since the peripheral edge portion 17 is rich in flexibility and extends well, it is easy to follow the unevenness around the eyes and can be easily adhered and pasted. Moreover, since the peripheral part 17 is translucent, since it can affix while confirming a sticking state, it can prevent that a sticking residue arises.
