Arm stabilizer device and methods
A device for supporting a patient's arm includes a rail clamp configured to be secured to a rail or other structure on a table such as an operating table. The rail clamp includes a clamp body and a socket configured to receive a base of an attachment such as a support arm or lateral brace. The base may be inserted longitudinally in the socket on the rail clamp. A stabilizer bar extends from the base in some embodiments. The base is moveable in the socket such that the stabilizer bar may be raised or lowered relative to the rail clamp. One or more modular attachments for supporting various regions of a patient's arm may be secured to the stabilizer bar or the rail clamp.
1. An arm positioning apparatus for mounting on a universal rail of an operating table and for supporting a patient's arm when the patient is lying in a supine position on the table, the apparatus comprising:
a rail clamp configured for attachment to the rail, the rail clamp including a clamp base and a clamp body protruding upwardly from the clamp base, the clamp body including a longitudinal section configured to extend away from the rail during use;
a humeral support mount disposed on the clamp body of the rail clamp, wherein the humeral support mount is moveable longitudinally along the clamp body on the rail clamp and the humeral support mount is configured to accept at least one attachment;
a humeral support fastener disposed on the humeral support mount, the humeral support fastener configured to secure the humeral support mount at a desired location relative to the rail clamp;
a socket defined in the rail clamp; and
a support arm including a base and a stabilizer bar extending from the base,
wherein the base is configured to be inserted longitudinally in the socket.
2. The apparatus of claim 1 , wherein the base is vertically adjustable in the socket relative to the rail clamp.
3. The apparatus of claim 2 , wherein the stabilizer bar is pivotable relative to the base.
4. The apparatus of claim 3 , further comprising a wrist support attachment disposed on the stabilizer bar.
5. The apparatus of claim 4 , wherein the wrist support attachment includes a wrist support mount disposed on the stabilizer bar and a wrist support bar extending from the wrist support mount.
6. The apparatus of claim 5 , further comprising an attachment groove defined on the stabilizer bar, wherein the wrist support mount is mounted in the attachment groove.
7. The apparatus of claim 6 , further comprising a reducer attachment disposed on the stabilizer bar.
8. The apparatus of claim 7 , wherein the reducer attachment includes a reducer attachment mount slidably disposed on the stabilizer bar.
9. The apparatus of claim 5 , wherein the wrist support mount is moveable along the stabilizer bar.
10. The apparatus of claim 7 , further comprising a humeral support attachment disposed on the humeral support mount on the rail clamp.
11. The apparatus of claim 3 , further comprising a clamp groove on the rail clamp.
12. The apparatus of claim 11 , wherein the clamp groove is a blind groove.
13. The apparatus of claim 11 , wherein the clamp groove is a clearance groove open to the base when the base is disposed in the socket, wherein the position of the base in the rail clamp is visible in the socket through the clamp groove.
