Hanging apparatus for fixing a medical device to a substantially horizontal or substantially vertical support structure
First Claim
1. A medical device hanging apparatus for facilitating the removable attachment of a medical instrument alternately to a vertical or a horizontal longitudinal support structure, the hanging apparatus comprising:
- a clamp shaft rotatable about a central longitudinal axis;
a clamp arm extending orthogonally from the clamp shaft;
an internal shaft positioned within the clamp shaft;
a tension spring fixed at a first end to at least one of the internal shaft and the clamp shaft;
a clamp housing that receives the clamp shaft, the clamp arm positioned external to the housing, a second end of the tension spring fixed to the clamp housing such that telescoping withdrawal of the clamp shaft from the clamp housing is resisted by the tension spring; and
a rotational cam mechanism, the cam mechanism positioned between the clamp housing and the internal shaft, wherein rotation of the internal shaft directs a longitudinal movement of the internal shaft and the clamp arm to effect a displacement of the internal shaft further into the clamp housing.

Abstract
A hanging apparatus is provided that facilitates the attachment of a medical instrument to a support structure. The mechanism includes a generally longitudinal, telescoping assembly that extends outward from the back of the medical instrument and positions a rotatable arm to serve as one face of a clamp, opposing the back of the medical instrument as the second face of the clamp. The mechanism assembly includes a cylindrical shaft that extends outward against the tension force of a spring from a housing component of the assembly. A cam mechanism within the hanging apparatus allows for locking and tightening of the clamp against the support structure after closure of the clamp under the influence of the tensioning spring.

7. A medical device hanging apparatus for facilitating the removable attachment of a medical instrument alternately to a vertical or a horizontal longitudinal support structure, the hanging apparatus comprising:
-
a clamp housing defining a longitudinal enclosure along which are positioned a first plurality of teeth; a clamp shaft retractably positioned within the longitudinal enclosure, the clamp shaft being rotatable about a central longitudinal axis; a clamp arm extending from the clamp shaft; an internal shaft rotatably positioned within the clamp shaft, the internal shaft having a substantially flat surface; and a locking member rotatably positioned on the internal shaft and including a second plurality of teeth, the locking member being positioned on the substantially flat surface of the internal shaft when the internal shaft is in an unlocked position, the locking member being moved off of the substantially flat surface when the internal shaft is rotated into a locked position, the placement of the internal shaft in the locked position displacing the locking member radially outward relative to the internal shaft such that the second plurality of teeth lockingly engage the first plurality of teeth. - View Dependent Claims (8, 9, 10, 11)
