Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to an upper limb side-lying hand rest. Background Art

[0002] The surgical position is a passive position placed during surgery to meet the needs of the operation. The correct surgical position is the premise for exposing the surgical field and successfully completing the operation, and is an important guarantee for the patient's safety. Improper surgical position leads to nerve damage, among which unreasonable arm placement leads to brachial plexus damage. The use of a side-lying armrest can meet the needs of supporting the patient's arm and ensure the surgical process. At present, the armrest is usually temporarily assembled using existing instruments in the operating room, which not only wastes time and is inconvenient to use, but also often affects intraoperative fluoroscopy, bringing many hidden dangers to the operation.

[0012] The armrest is fixed to the operating bed through the supporting fixing columns at the bottom and the components conventionally equipped in the operating room. The armrest is divided into two shelf parts, the upper arm and the forearm. In order to meet the arm length requirements of different patients, the plug-in rod and the slide groove provided on the upper arm shelf can adjust the length of the upper arm shelf, thereby improving the applicability of the upper limb side-lying armrest. The two rotating adjustment mechanisms can adjust the angle between the upper arm shelf and the forearm shelf and the horizontal angle of the upper arm shelf, thereby better meeting the needs during surgery, further avoiding obstruction of the limbs during fluoroscopy, and better ensuring the smooth progress of the operation.

When the pull ring 47 is released, the ratchet 42 is reset under the elastic action of the spring 43, so that the ratchet 42 locks the ratchet wheel 48 to prevent the forearm rest 2 from rotating. At the same time, the pull ring 47 is also placed in the pull ring seat 46 for fixation.

[0028] In this embodiment, the surfaces of the first upper arm rest 12 , the second upper arm rest 13 and the forearm rest 2 are all fixedly connected with a soft support pad 7 .

[0029] Specifically, the soft support pad 7 can effectively increase the comfort of the patient's upper limb support without affecting the perspective.
