Abstract

A cervical traction assembly for use with a patient support apparatus includes an adjustment carriage track member including a connecting bracket assembly that releasably connects to a mount support member of the patient support apparatus. The adjustment track member includes a track body including a pair of opposing sidewalls that are spaced-apart from each other to define an elongated channel therebetween. Each sidewall includes a guide track that extends along a length of the respective sidewall. A rope angle adjustment carriage is located within the channel. The rope angle adjustment carriage includes a first track engagement member that is received by one of the guide tracks of one of the sidewalls and a second track engagement member that is received by another of the guide tracks of another of the sidewalls. The first track engagement member has a locked configuration that inhibits movement of the rope angle adjustment carriage.

First claim

What is claimed is:

1. A cervical traction assembly for use with a patient support apparatus, the cervical traction assembly comprising:
an adjustment carriage track member that mounts to a mount support member of a forward column assembly of the patient support apparatus, the adjustment carriage track member comprising a track body comprising an elongated channel and a guide track that extends along a length of the elongated channel; and
a rope angle adjustment carriage that is located within the elongated channel, the rope angle adjustment carriage comprising a track engagement member comprising an engagement projection received by the guide track;
wherein the track engagement member has a locked configuration that inhibits movement of the rope angle adjustment carriage along the elongated channel and an unlocked configuration that allows movement of the rope angle adjustment carriage along the elongated channel.

2. The cervical traction assembly of claim 1 , wherein the guide track is a first guide track, the first guide track having a first side and second side opposing the first side, the second side having undulating peaks and valleys that provide the first guide track with regions of decreased and increased width.

3. The cervical traction assembly of claim 2 , wherein the track engagement member comprises:
a body; and
the engagement projection that extends a width of the body;
wherein the track engagement member is moveable between the locked configuration with the engagement projection received within one of the valleys of the first guide track to prevent movement of the track engagement member along the first guide track and the unlocked configuration with the engagement projection removed from the one of the valleys of the first guide track to allow movement of the track engagement member along the first guide track.

4. The cervical traction assembly of claim 3 , wherein the adjustment carriage track member comprises a second guide track that extends along a length of the elongated channel, the second guide track having a first side and second side opposing the first side of the second guide track, the second side of the second guide track having undulating peaks and valleys that provide the second guide track with regions of decreased and increased width.

5. The cervical traction assembly of claim 4 , wherein the rope angle adjustment carriage comprises a second track engagement member comprising:
a body; and
an engagement projection that extends a width of the body;
wherein the second track engagement member is moveable between a locked configuration with the engagement projection of the second track engagement member received within one of the valleys of the second guide track to prevent movement of the second track engagement member along the second guide track and an unlocked configuration with the engagement projection of the second track engagement member removed from the one of the valleys of the second guide track to allow movement of the second track engagement member along the second guide track.

6. The cervical traction assembly of claim 5 , wherein the first track engagement member is a first track engagement member, wherein the first track engagement member and the second track engagement member are configured to be depressed to their unlocked configurations.

7. The cervical traction assembly of claim 6 , wherein the body of the first track engagement member includes a recessed region that engages an edge of the first guide track with the first track engagement member in the locked configuration.

8. The cervical traction assembly of claim 1 , wherein the rope angle adjustment carriage has a rope pass-through opening.
