Embodiment Construction

[0030] figure 1 A holding arm 10 is shown which has a plurality of rigid holding parts 12 , 14 , 16 , 18 , 20 and 22 which are coupled to one another via joints 24 , 26 , 28 , 30 and 32 . At one end of the holding arm 10 there is provided a fastening device 34 for mounting the holding arm 10 on a slide rail (not shown) of the operating table. At the other end of the holding arm 10 there is a handle 36 which can be manually actuated by the user in order to unlock the holding arm 10 .

[0031] If no actuating force is applied to the handle 36 , the holders 12 , 14 , 16 , 18 , 20 and 22 of the holder arm 10 are rigidly coupled to one another via the joints 24 , 26 , 28 , 30 and 32 . In this state, the holding arm 10 forms a rigid unit.

[0032] If the user presses the handle 36, the holders 12, 14, 16, 18, 20 and 22, which are coupled to each other via the joints 24, 26, 28, 30 and 32, can move relative to each other via the unlocking mechanism, so that the user can The holdin...

Abstract

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.

Description

technical field [0001] The invention relates to a medical holding arm according to the preamble of claim 1 . Background technique [0002] Currently, for surgical applications there is an increasing use of auxiliary systems comprising, for example, articulated arms which can be mounted on slide rails of operating tables. Such holding arms are used, for example, for arm support during shoulder surgery. The holding arm has a plurality of rigid holding parts which are movably coupled to one another via joints. As a result, the holding arm can move freely in all spatial directions and is held securely in the desired position. [0003] The joints, which respectively couple the two rigid holding parts of the holding arm to one another in a freely movable manner, have a first joint body connected to a holding part and a second joint body connected to the second joint body. Another holder is connected. In order to secure the two holding parts to one another in the desired config...
