Abstract
【解決手段】ロッド受取り部材(4,20,59)のボア(6,6a,73)内において外科手術装置(16,51)のロッド部(2,2a,67)を固定するためのロッド接続部(1)は、内径を有するボアを含むロッド受取り部材と、外径を有するロッド部とを含み、ロッド部はボアに導入され、ボアの内径およびロッド部の外径は、ロッド部がロッド受取り部材のボアにプレス嵌めされるように選択され、さらにボアはロッド部の外壁面(9,77)に対向する内壁面(8,75)を有し、内壁面または外壁面は、ロッド部とロッド受取り部材との間の接触表面積を減じるために少なくとも1つの凹部(12,71)を備える。
【選択図】図5B
Description
なる。
う設計された領域内では内壁面が突出部も凹部も有さない、(円筒状)内壁面108を有する。ロッド状部材102は外径を有し、外径は、結果として両方の部材間に固定したプレス嵌めを生じる締め代を与えるために、ボア106の内径よりも僅かに大きい。
14fの10mm−15mmの値に向かって減少する(これがL5−S1を安定化する)。したがって、下部胸部を考えると、ロッド装置16およびその部品の小型化に関する要求が強くなる。
