FASTENING DEVICE FOR FASTENING ACCESSORY PARTS TO MEDICAL DEVICES

摘要

A fastening device (1) for fastening accessory parts to medical devices has a first stationary claw (3), a second claw (4) which can be displaced towards the first claw (3), and a drive device for displacing the second claw (4) in the direction of clamping (a). The drive device has a cam slot (6) and a support device (9), the cam slot (6) being provided with a control surface (10) for transmitting a movement of the cam slot (6) in a direction of actuation (b) to the second claw (4) and also being provided with a support surface (7). The support device (9) is designed such that the cam slot (6) is supported by the support surface (7) relative to the first claw (3) on the support device (9), the control surface (10) enclosing a first angle (a) in a first region (I) of the control surface (10) in the direction of clamping (a) and enclosing a second angle (ß) in at least one second region (II) of the control surface (10), and a distance becoming substantially continuously larger in the direction of clamping (a) between the control surface (10) and the support surface (7) along the control surface (10) in a direction of actuation (b).
