Description

TECHNICAL FIELD The present invention relates to an operation assisting tool that is placed on a table and a part of an upper limb is placed thereon for use.

With respect to the operation assisting tool, various types have been proposed, for example, as disclosed in Patent Documents 1 and 2 below. However, since these operation aids are used by placing part of the upper limbs (hands, wrists, forearms, elbows, upper arms and shoulders), specifically the hands, wrists, or forearms, they are used to reduce fatigue in the upper limbs. Although effective, it is not so effective in reducing neck, back and waist fatigue.

Fatigue of the neck, back and lower back is related to the posture of the upper body during operation. That is, when the posture of the upper body is proper, the burden on the neck, back, and waist is greater when the posture is forward leaning, and the burden causes fatigue on the neck, back, and hips, and the accumulation of the fatigue causes daily fatigue. There is also a possibility that it may lead to a life-threatening medical condition such as cervical disc herniation or lumbar disc herniation.
