Description
(1.開示の分野)
本開示は、痔疾部を処置することにおける使用のための器具、そしてより特定すれば、痔疾部組織を切断およびシールするためのエネルギーを基礎にしたデバイスに関する。
痔疾部は、肛門の丁度内側に位置決めされる結節状静脈の膨潤し捩れた塊である。痔疾部は、慢性的な緊張形態、例えば、便秘および出産により引き起こされる。慢性的な緊張は、静脈内の弁を損傷し、そして静脈血が集まり、そして静脈を通常サイズの多数倍まで膨張する。静脈内の血液の遅延した流れは、静脈にさらなる損傷、および血栓症を引き起こし得る。患者が年をとるにつれ、肛門の組織の弾力性は変化し、そして痔疾部の状態は悪化し得、脱肛および肛門出血を引き起こす。致死的であることは稀であるが、痔疾部はしばしば痛みをともなう。処置は、熱パックおよびベッド休息(温和な場合)から手術(極度の場合)の範囲であり得る。
本開示は、新規なエネルギーを基礎にした部分的周縁痔疾部修復デバイスを提供し、これは、侵入し、かつこのデバイスによってシールされる痔疾部組織の改良された見通しを可能にする。本開示のデバイスは、巾着配置の必要性を取り除く。なぜなら、痔疾部組織が標準的なグラスパー(把持器)を通じて、またはこの痔疾部修復デバイスアセンブリ内の痔疾部組織を取り囲むことにより引き出され得るからである。このエネルギーを基礎にした部分的周縁痔疾部修復デバイスの形態は、完全な周縁の代わりに、個々の痔疾部または特異的領域の除去を可能にする。しかし、このエネルギーを基礎にした部分的周縁痔疾部修復デバイスはまた、その場にある間、全周縁の周りで痔疾部組織を除去するために回転され得ることが企図される。
本明細書で開示されるエネルギーを基礎にした部分的周縁痔疾部修復デバイスの実施形態を図面を参照してここで説明し、図面では、同様の参照番号は、いくつかの図面を通じて対応する要素を識別する。
アクチュエータアセンブリ、およびこのアクチュエータアセンブリに作動可能に連結されたエネルギーを基礎にした部分的周縁痔疾部修復デバイスヘッドアセンブリを含むエネルギーを基礎にした部分的周縁痔疾部修復デバイスであって、ここで、このヘッドアセンブリは、近位電極アセンブリおよび遠位電極アセンブリを含み、そしてさらにここで、少なくとも1つの電極アセンブリは、その上に取り付けられた電極を含み、この2つの電極アセンブリが接近するとき、痔疾部組織のシールを容易にする。
