Description
Claims (8)
- 管腔内に挿入される挿入機器の挿入部に装着されて、該挿入部の長手軸周りに回転自在に配置されるユニット本体と、
前記ユニット本体の外周面に接着または溶着によって直立状態に固定して突設され、前記ユニット本体の長手軸に沿って螺旋状に延設された、予め定めた可撓性及び弾発性を有する弾性部材からなる弾性凸部と、
を具備し、
前記弾性凸部を前記挿入部の先端側に向けて倒すために必要な第1力量を、管腔壁を圧縮しつつ前記挿入部を管腔深部に向けて前進させる際、前記弾性凸部の挿入部基端側に圧縮された管腔壁が元の状態に戻ろうとする管腔壁からの反力よりも大きな力量に設定すると共に、前記弾性凸部を前記挿入部の基端側に向けて倒すために必要な第2力量を、前記挿入部を管腔深部に向けて前進させる際に、管腔壁から前記弾性凸部に付与される外力より小さな力量に設定し、更に、前記第1力量が前記第2力量より大きくなるように設定した、装着ユニット。 - 前記弾性凸部は、細長で中実に形成されている、請求項1に記載の装着ユニット。
- 前記弾性凸部は、前記弾性部材を第1接着剤および該第1接着剤と異なる第2接着剤によって前記ユニット本体の外周面に固定され、
前記ユニット本体の外周面に設けられた前記弾性凸部は、該弾性凸部の挿入部先端側に前記第1接着剤が硬化した第1硬化部を有し、当該弾性凸部の挿入部基端側に前記第2接着剤が硬化した第2硬化部を有し、
前記第1硬化部の硬度が前記第2硬化部の硬度より高い、請求項2に記載の装着ユニット。 - 前記弾性凸部は、前記弾性部材が接着、または、溶着によって前記ユニット本体の外周面に固定されてなり、
前記ユニット本体の外周面に設けられた前記弾性凸部は、該弾性凸部の挿入部先端側に第1固定部を有し、当該弾性凸部の挿入部基端側に第2固定部を有し
前記第1固定部の断面積が前記第2固定部の断面積より大きい、請求項2に記載の装着ユニット。 - 前記弾性凸部に、該弾性凸部が延設される方向に沿って延びる中空部を設けた、請求項1に記載の装着ユニット。
- 前記中空部は、前記弾性凸部の挿入部先端側における肉厚と挿入部基端側における肉厚とが異なる、請求項5に記載の装着ユニット。
- 前記弾性凸部は二種類の板状弾性部材を一体にして形成されると共に、前記弾性凸部の挿入部先端側に設けられた第1板状弾性部材の剛性が、該弾性凸部の挿入部基端側に設けられた第2板状弾性部材の剛性より高く設定されている、請求項2に記載の装着ユニット。
- 前記第1板状弾性部材の厚みが前記第2板状弾性部材の厚みより厚く形成されている、請求項7に記載の装着ユニット。
