医疗的保持臂
摘要：
本发明涉及一种医疗的保持臂，其包括至少一个具有两个关节体(40、42)的关节(24、26、28、30、32)，所述关节体绕旋转轴线(D)相互可扭转，其中，所述关节体的第一关节体(40)具有多个卡锁销(46)并且所述关节体的第二关节体(42)具有多个卡锁凹部(48)，卡锁销(46)的数量不同于卡锁凹部(48)的数量，卡锁销(46)分别具有一个沿轴向逐渐变细的嵌接部分(66)，卡锁凹部(48)分别沿轴向逐渐变细地构造，用于可选择地、闭锁关节(24、26、28、30、32)地容纳每个所述嵌接部分(66)，并且在关节(24、26、28、30、32)闭锁时，至少其中一个卡锁销(46)以其逐渐变细的嵌接部分(66)完全容纳在其中一个逐渐变细的卡锁凹部(48)中，而至少其中一个另外的卡锁销(46)以其逐渐变细的嵌接部分(66)仅部分容纳在其中一个另外的逐渐变细的卡锁凹部(48)中。相应的卡锁销(46)的嵌接部分(66)具有至少一个削平的第一贴靠面(68)，并且相应的卡锁凹部(48)具有至少一个削平的第二贴靠面(72)。在相应的卡锁销(46)的嵌接部分(66)容纳在相应的卡锁凹部(48)中时，第一和第二贴靠面(68、72)至少部分地相互面接触。
摘要（英）：

A medical holding arm is described, comprising at least one joint (24, 26, 28, 30, 32) with two joint bodies (40, 42) which are pivotable relative to each other about a pivot axis (D), wherein a first of the joint bodies (40) has a plurality of locking pins (46) and a second of the joint bodies (42) has a plurality of locking recesses (48), the number of locking pins (46) differs from the number of locking recesses (48), the locking pins (46) each have an axially tapered engagement part (66), the locking recesses (48) are each axially tapered to receive each of the engagement parts (66) for locking the joint (24, 26, 28, 30, 32), and, when the joint (24, 26, 28, 30, 32) is locked, at least one of the locking pins (46) is received with its tapered engagement part (66) completely in one of the tapered locking recesses (48), while at least one of the other locking pins (46); is received with its tapered engagement part (66) only partially in one of the other tapered locking recesses (48). The engagement part (66) of the respective locking pin (46) has at least one first flattened contact face (68), and the respective locking recess (48) has at least one second flattened contact face (72). When the engagement part (66) of the locking pin (46) is received in the respective locking recess (48), the first and second contact faces (68, 72) are at least partially in planar contact with each other.
