【発明の詳細な説明】 DETAILED DESCRIPTION OF THE INVENTION

【0001】 [0001]

【発明の属する技術分野】この発明は、涙道再建用挿管器具に関するものである。 [Field of the Invention The present invention relates to apparatus for intubation for lacrimal duct reconstruction.

【0002】 [0002]

【従来の技術】挿管法は、涙道の再建に有効な治療法である。 BACKGROUND OF THE INVENTION intubation is an effective treatment for reconstruction of the lacrimal duct. しかし、クロフォード法に代表される従来のシリコーンチューブ留置法は、日本においてはヌンチャク型シリコーンチューブに比較して一般には普及していない。 However, conventional silicone tube indwelling method represented in Crawford methods generally are not widespread in comparison with Nunchuk silicone tubing in Japan. これは、涙道内に留置されたシリコーンチューブに十分な安定性がなかったためである。 This is because there was not enough stability to the left in lacrimal duct silicone tube.

【0003】従来のシリコーンチューブは、例えばシリコーンゴムで形成されるが、柔軟性が充分でなかった。 Conventional silicone tubing, for example, be formed of silicone rubber, the flexibility is not sufficient.
従って、その中央部をピンセットで持ち上げても、逆U Therefore, even if lifting the central part with tweezers, inverted U
字形に楽に折れ曲ることはなかった。 It did not comfortably broken flex in shape. この弾力性が涙道内での不安定性の一因になっていた。 This elasticity has been a cause of instability in the lacrimal duct.

【0004】また、クロフォード法では、チューブの先端を鼻腔内で結び、鼻涙管下端の開口部の大きさより大きな結び目を作りそのまま放置する構成になっていた。 [0004] In Crawford method, the distal end of the tube connected by intranasal, creating a large knot than the size of the opening of the nasolacrimal duct lower end was still intact on standing configuration.
しかし、鼻涙管下端の開口部の大きさを確認することは困難である。 However, it is difficult to confirm the size of the opening of the nasolacrimal duct bottom. また、結び目が鼻涙管下端の開口部より小さいときは、結び目が上方に移動して涙嚢内に入ってしまう難点もあった。 Moreover, the knot is smaller than the opening of the nasolacrimal duct lower end, the knot was also difficulty accidentally get tears sac moves upward. 涙小管の径が非常に小さいため、一度涙嚢に入った結び目を抜去することは非常に困難であった。 Since the diameter of the canaliculus is very small, it is very difficult to removed the knot entering once lacrimal sac.

【0005】そこで本発明者は、図1に示すように全長が80〜130mmであり、中央部の20〜40mmが細くしなやかになったチューブを提案した。 [0005] The present inventors have, overall length as shown in FIG. 1 is a 80~130Mm, proposed a tube 20~40mm the central portion becomes thin and supple. このチューブは、中央部が細くかつしなやかで、その両側が太く硬めになっていて、図2に示すように中央部を支持すると重力で楽に逆U字形に湾曲する構成になっている。 This tube is a middle portion thin and flexible, they become both sides thicker stiffer, and is configured to bend to comfortably inverted U in the supporting force of gravity the central portion as shown in FIG. 従って、このチューブは、従来のシリコンチューブと比較して安定性が格段に優れていて、抜け出しが起ることは非常に稀である。 Thus, the tube, stability is not much better in comparison with the conventional silicon tube, the exit occurs is very rare.

【0006】また、このチューブは両端が盲端になっていて、消息子を挿入する切れ目を有するので、涙道内への挿入も容易である。 [0006] In addition, the tube ends have become a blind end, because it has a cut to insert an anti-son, insertion into the lacrimal duct is also easy. さらに、抜去も容易にできる等の利点を有している。 Further it has advantages such removal can be facilitated.

【0007】本発明者は、このチューブを100例以上の涙道閉塞の症例に適用したが、涙道内での安定性及び抜け出しが稀であることが確認されている。 [0007] The present inventors has been applied to the tube to cases 100 cases over lacrimal duct obstruction, it has been confirmed that stability in the lacrimal duct and exit are rare.

【0008】 [0008]

【発明が解決しようとする課題】しかしながら、一般に、チューブの両端は涙道の働きによって鼻腔の方に引っ張られる。 [SUMMARY OF THE INVENTION However, in general, both ends of the tube is pulled toward the nasal cavity by the action of lacrimal duct. このため、図3に示すように、チューブ中央部の細くしなやかな部分40が涙点や涙小管に食い込んで、涙点や涙小管に裂傷19が生じる場合があった。 Therefore, as shown in FIG. 3, thin flexible portion 40 of the tube central portion bites into the lacrimal punctum and canaliculus, there are cases where fissures 19 occurring in the punctum or canaliculus.
裂傷は、チューブ中央部が細く硬いほど生じ易い傾向があった。 Lacerations, the center of a tube there is a tendency to occur harder thinner. また、両側からの張力が大きい場合には、チューブ中央部がさらに細くなることによってさらに裂傷1 Further, when the tension from both sides is large, further laceration by the tube center portion is further thinner 1
9が生じ易くなっていた。 9 had become liable to occur.

【0009】このような従来技術の問題点に鑑み、本発明は、涙道内での安定性が良く、涙道内への挿入も容易であって、留置後に涙点や涙小管に裂傷が生じる恐れが無い涙道再建用挿管器具を提供することを目的としている。 [0009] fear view of such problems of the prior art, the present invention has good stability in the lacrimal duct, insertion into the lacrimal duct even easier, the laceration punctum or canaliculus after placement occurs is an object of the present invention to provide a there is no tears road reconstruction for intubation device.

【0010】 [0010]

【課題を解決するための手段】本発明の解決手段は、請求項1〜25に記載された涙道再建用挿管器具である。 Solution of the invention To achieve the above object, according to a lacrimal duct reconstructive intubation device of claim 1 to 25.
