WO2019131064A1 ジョイント部材、処置具、処置具の屈曲制御方法 审中-公开

ジョイント部材、処置具、処置具の屈曲制御方法
摘要：
互いに略共軸に並設されて屈曲可能な処置具を構成する略筒状のジョイント部材１２であって、ジョイント部材１２の軸方向ＡＤの一端側に凹部Ｃ１１、１２が形成され、ジョイント部材１２の軸方向ＡＤの他端側に凸部Ｐ１１、１２が形成され、互いに隣接する２つのジョイント部材における一方のジョイント部材の凹部Ｃ１１、１２が、他方のジョイント部材の凸部Ｐ１１、１２と摺接するようになっており、ジョイント部材１２は、管状部材１２１と、管状部材１２１に対して軸方向ＡＤと垂直方向に横断して配置された板状部材１２２と、を備え、板状部材１２２は、板状部材１２２を軸方向ＡＤに貫通する屈曲用貫通孔、及び、板状部材１２２を軸方向ＡＤに貫通するデバイス用貫通孔を備える、ジョイント部材１２。
摘要（英）：

Substantially cylindrical joint members 12 are arranged in parallel substantially coaxial to one another and constitute a treatment tool that allows for flexure, wherein: recesses C11, C12 are formed on one end side of each joint member 12 in an axial direction AD; protrusions P11, P12 are formed on the other end side of each joint member 12 in the axial direction AD; the recesses C11, C12 of one joint member among two adjacent joint members are brought into sliding contact with the protrusions P11, P12 of the other joint member; each joint member 12 is provided with a tube-shaped member 121, and a plate-shaped member 122 disposed across a direction perpendicular to the axial direction AD with respect to the tubular member 121; and each plate-shaped member 122 is provided with a flexure through-hole that passes through the plate-shaped member 122 in the axial direction AD, and a device through-hole that passes through the plate-shaped member 122 in the axial direction AD.
