Description
本出願は、「骨盤の症状を治療するための、器具、及び方法」と題された2011年6月13日出願の米国仮特許出願第61/482,430号、及び、「骨盤の症状を治療するための、インプラント、器具、及び方法」と題された2011年5月4日出願の米国仮出願第61/496,127号について、35U.S.C§119(e)に基づく権利を主張する。両方の文献共、参照されることによって、それらの全体が本明細書に組み込まれるものとする。
本発明は、骨盤組織をサポートするための骨盤インプラントを用いて骨盤の症状(状態)を治療する器具及び関連方法に関するものである。骨盤の治療には、例えば、腹腔鏡下での、開腹での、及び経膣での、外科手術による脱膣の治療、が含まれる。
男性及び女性の骨盤の健康は、人々の高齢化のために、少なくとも幾分は重要性が増している医療分野である。一般的な骨盤の病気の例としては、失禁(例えば、便失禁や尿失禁)、骨盤組織の脱出症(例えば、女性の膣脱)、そして骨盤底に影響を与える他の症状が含まれる。このような骨盤障害は、衰弱又は通常の骨盤を支えるシステムの損傷によって引き起こされることがある。共通の病因は、分娩、子宮の摘出、結合組織の欠陥、長期の肉体重労働、及び閉経後の萎縮症を含む。
本明細書に記載された、器具、システム、及び方法は、例えば、失禁(例えば、大便失禁、腹圧性尿失禁、急迫性失禁、混合型尿失禁などの種々の症状)、膣脱(例えば、腸ヘルニア、膀胱瘤、直腸瘤、尖部又は円蓋の脱症状、子宮降下などの様々な症状)、及び、筋肉や靭帯の衰弱、子宮摘出などによって引き起こされる他の症状、のような骨盤の症状を治療するために使用できる。本発明によれば、仙骨膣固定術の処置は、開腹した開口部を介して、腹腔鏡下で、又は経膣で、行うことができ、その処置は、本発明の手段及び/又は方法の実施形態を使用できるそれぞれ異なるアプローチが必要になる。
本発明を、さらに、添付の図面を参照しながら説明する。ここでは、同様の構造は、いくつかの図面を通して同じ番号にて参照される。
ここで説明する方法及び器具は、仙骨膣固定術の処置(例えば、経膣での、及び開腹での)に限定されるものではなく、一緒に行う直腸脱、膀胱瘤、腸ヘルニア及び他の原因に起因する膣円蓋脱を治療するための処置を含む、膣組織を支持する処置に有用である。仙骨膣固定術は、膣円蓋の吊り上げを行う処置であり、メッシュ又は他の材料から成る帯(細長片)のようなインプラントの使用によって達成することができる。他の材料とは、仙骨(骨自体)、周辺仙靭帯、子宮仙骨靱帯、又は仙骨岬角での前縦靱帯などの仙骨の解剖学的構造の部位又は要素に対する後方の膣組織(例えば、膣カフ)のものであり、仙骨に移植される骨ねじを用いて達成することができる。仙骨固定術は、腹部切開、膣切開、又は腹腔鏡を介して実行されてもよい。合成メッシュのようなインプラントは、慎重に外科医によって、特殊な形状にカスタマイズされたり、組み立てられたりすることができる。また、子宮摘出を含むいくつかの仙骨膣固定術の処置では、インプラントは、子宮及び子宮頸部の除去後に残る膣組織後部に代替的に取り付けることができる。また、解剖学的構造に、仙骨の又はその周りの膣組織をサポートするために、例えば、子宮仙骨神経の靭帯又は仙骨自体に(すなわち、仙骨の解剖学的構造の要素に)取り付けることができる。
