Abstract

A mounting apparatus of the present invention is used in a medical environment to releasably secure a device to a support member. The mounting apparatus has a flexible shaft with a first end for releasable attachment to the support member and a second end for releasable attachment to the device. A generally C-shaped clamping member at the first end releasably attaches the apparatus to the support member. The clamping member has an inner surface, an outer surface, and at least two apertures including a first aperture through which a securing rod passes and a second aperture for releasable attachment of the flexible shaft. The present invention is also directed to a powered medical device assembly having a medical device and a flexible shaft capable of selective mounting of the medical device on a support.

Claims

1. A clamping apparatus for use in a medical environment to releasably secure a device to a support member, said clamping apparatus comprising:

a flexible shaft having a first end for attachment to the support member and a second end for attachment to the device; and

a clamp including a securing rod and a generally C-shaped clamping member at said first end for selectively mounting the apparatus to said support member, said clamping member having a lower portion, a middle portion extending generally upwardly from the lower portion, a first upper portion extending from the middle portion and upwardly bent relative to the middle portion, a second upper portion extending from the first upper portion and downwardly bent relative to the first upper portion forming a bend between the first and second upper portions, a first threaded aperture in the lower portion, a second threaded aperture in the bend and a third aperture in the clamp, the flexible shaft being attachable to the middle portion of the clamping member;

the first and second threaded apertures each being configured for receiving the securing rod to mount the apparatus to said support member, the first aperture opening toward the first and second upper portions and the second aperture opening toward the lower portion.

2. A clamping apparatus as set forth in claim 1 wherein the clamping member comprises an inner surface having an opening sized to receive said support member, the clamp having a modular configuration such that the inner surface is adapted to receive a support member in the form of a pole and a support in the form of a planar support such that the inner surface contacts the support member at least two points of contact, the two points of contact being on the first end second upper portions, respectively.

3. A clamping apparatus as set forth in claim 1 further comprising a threaded fastener, and wherein the third aperture is a bore and the flexible shaft has a threaded bushing mounted on said first end, said clamping member being secured to the flexible shaft by the threaded fastener passing through the bore and mating with the threaded bushing.

4. A clamping apparatus as set forth in claim 3 wherein the clamping member has an outer surface and a shoulder extending from the outer surface, and the threaded bushing comprises a notch, the shoulder being sized to be received in the notch when the flexible shaft is connected to the clamping member to prevent rotation between the clamp and flexible shaft.

5. A clamping apparatus as set forth in claim 3 wherein said flexible shaft comprises a locking collar mounted for sliding, linear movement at said second end for quick release connection to the device, said locking collar having at least one detent element for releasable engagement with the device.

6. A clamping apparatus as set forth in claim 1 wherein the flexible shaft comprises a spring forming a part of the shaft and a rigid tube forming another part of the shaft.

7. A clamping apparatus for use in a medical environment to releasably secure a device to a support member, said clamping apparatus comprising:

a flexible shaft having a first end for attachment to the support member and a second end for attachment to the device; and

a clamp including a securing rod and a generally C-shaped clamping member at said first end for selectively mounting the apparatus to said support member, said clamping member having an inner surface, an outer surface and at least two apertures including a first aperture through which the securing rod passes and a second aperture for attachment of the clamping member to said flexible shaft;

the flexible shaft comprising a locking collar mounted for sliding, linear movement at said second end for quick release connection to the device, said locking collar having at least one detent element for releasable engagement with the device.

8. A clamping apparatus as set forth in claim 7 in combination with a mounting stud adapted to be mounted on the device, the mounting stud including a locking recess adapted to accept the at least one detent element.
