A kind of Clairvoyant type Extension support of this case system this case what operating table is to be made of a frame, two groups of sliders and two pairs of supporting pads. The frame has a pair of the first parallel sliding rail axial each other,And this is equipped with the bridging axis that a pair radially extends to the first sliding rail front end outer side； Two groups of sliders have it is opposite be arranged what this to before the first sliding rail,Two pairs of sliding seats of Hou side,Wherein each pair of sliding seat the second sliding rail that radially one nonmetallic materials of tipping are made,And each sliding seat be spirally connected one can to this first,Second sliding rail solid lock and the first knob of release,Use adjust two pairs of sliding seats before this is to the first sliding rail,Hou distance； And each pair of supporting pad is arranged what the second sliding rail left and right sides,Each supporting pad has a sliding rack,And each sliding rack be spirally connected one can to second knob of the second sliding rail solid lock and release,Use adjustment each pair of supporting pad second sliding rail a left side,Right distance.本案係一種本案用於手術台之透視型延伸架，其係由一框架、兩組滑動器及兩對支撐墊所組成。該框架具有一對互為軸向平行之第一滑軌，且該對第一滑軌前端外側設有一對徑向延伸之跨接軸；該兩組滑動器具有相對套設於該對第一滑軌前、後側之兩對滑動座，其中各對滑動座徑向接裝一非金屬材料製成之第二滑軌，且各滑動座螺接一可對該第一、第二滑軌固鎖及鬆開之第一旋鈕，藉以調整該兩對滑動座在該對第一滑軌的前、後距離；而各對支撐墊套設於該第二滑軌左右側，該各支撐墊具有一滑動架，且各滑動架螺接一可對該第二滑軌固鎖及鬆開之第二旋鈕，藉以調整各對支撐墊在該第二滑軌的左、右距離。
