Abstract: A support mechanism for operation auxiliary tools includes a fixing unit, a support lever movably mounted on the fixing unit, a first bar movably connecting with an end of the support lever, a limiting unit engaging with another end of the first bar, and a second bar connecting with the limiting unit. The fixing unit engages with the operation bed, and operation auxiliary tools are placed on the second bar. The support lever, the first bar and the second bar are adjusted freely and positioned by the limiting unit. The limiting unit maintains the first bar and the second bar at desired freedom. The support mechanism is placed firmly with a predetermined angle and position, making operations more stable.

Abstract: An expansion mechanism for minimally invasive lumbar operation has a support member, a plurality of sliders movably assembled on the support member, at least a couple of outside muscle hook members mounted on adjacent sliders, an inside muscle hook member assembled on the slider, and a nerve hook member assembled on the slider. The expansion mechanism for minimally invasive operation makes small incisions and hurts less tissues. Furthermore, the expansion mechanism protects nerve tissues from repeated stirring. Muscles can be drawn apart without the need of removing ligament, obtaining clear and large operation vision.
