Problems solved by technology
[0005] However, the above-mentioned scheme still has deficiencies. There is a certain processing error or accuracy range in the barrel diameter and piston rod diameter of the large and small oil cylinders, and there is always an error in the actual effective area. In addition, there is always infiltration between the rodless chamber and the rod chamber of the same oil cylinder. Leakage, these internal leakage and errors gradually accumulate, will affect the synchronization and balance of the two cylinders

Embodiment Construction
[0018] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0019] figure 1 A simplified representation of an operating table with a column is shown. Such as figure 1 As shown, the patient support table is installed on the top of the column, and the patient support table is composed of a first section 1 , a second section 2 , a third section 3 and a fourth section 4 . The present invention is installed under the second section 2 and the third section 3, and includes a set of series double oil cylinder system and two pairs of arc-shaped slider slide rail pairs, which are used to realize the adjacent second section 2 and the third section Mutually adjusted turns between the segments 3 . Among them, the two oil cylinders 9 and two pairs of arc-shaped slider slide rail pairs of the series double oil cylinder system are respectively installed on both sides of the patient support surface of the operatin...

The invention relates to a turning supporting mechanism of a patient supporting surface of an operating table, comprising a tandem double oil cylinder system and two pairs of circular-arc slide block and slide rail pairs, wherein two oil cylinders of the tandem double oil cylinder system and the two pairs of circular-arc slide block and slide rail pairs are respectively installed on two sides of the patient supporting surface of the operating table; the two oil cylinders are fixed in the same section; the ends of piston rods of the two oil cylinders are respectively connected with one ends ofthe circular-arc slide blocks; the circular-arc slide blocks are arranged in the circular-arc slide rails to form the circular-arc slide block and slide rail pairs; the other ends of the circular-arcslide blocks are connected with the other adjacent section; two opposite one-way valves are respectively installed on the pistons of the two oil cylinders of the tandem double oil cylinder system; and a firing pin opposite to the one-way valves is respectively installed at the bottoms of rodless cavities of the two oil cylinders. Under the premises that the cost is not increased and the light transmittance is not affected, the invention realizes synchronous turning of the sections of the operating table, and enables a turning center to be above a supporting turning machine of the patient supporting surface.
Description
technical field [0001] The invention relates to the field of medical beds, in particular to a folding support mechanism for a patient support surface of an operating table that realizes synchronous folding of operating table sections without increasing costs and affecting light transmission. Background technique [0002] There are various types of patient support surfaces, the individual sections or segments of which can be pivoted or adjusted relative to one another. Turning can be manual or electric (motor, electro-hydraulic), realized by hinge mechanism. In order to increase the X-ray transmission range of each section, the deflection and adjustment mechanisms are located on both sides of each section. If the two sides of the same section are not evenly loaded, it will increase the difficulty of synchronizing the turning mechanisms on both sides. Because the two sides of the turning mechanism are not synchronized, the patient's support surface is distorted, which affect...
