The invention relates to a surgical operating table (1), which is intended for shoulder operations or surgical procedures performed on a similar part of the body. The surgical table comprises a platform (2) for the patient and an adjustment pedestal portion (3) with the platform (2) rested thereupon. The platform (2) has preferably a plurality of sections (21, 22, 23), which are connected to each other and capable of being pivoted at least in vertical plane, and upon which the patient is rested while a surgical procedure is performed. These sections include a back support (23), which comprises a basic back section (4), a middle back section (5) protruding therefrom, and two shoulder sections (6; 6a, 6b) disposed on either side of the middle back section (5) and releasably secured to the basic back section (4) by means of attachment elements (7). According to the invention, the attachment elements (7) comprise first and second attachment elements (7a, 7b), such that the shoulder section (6; 6a, 6b) is provided with first attachment elements (7a), which comprise an inclined protrusion (62) and, in engagement therewith, a gutter (63) which is disposed at an end (61) of the shoulder section, and the basic back section (4), particularly sides (40; 40a, 40b) of the basic back section, are provided with second attachment elements (7; 7b) comprising a frame portion (71), a rod (72), and a gap (73) therebetween. In a securing process of the shoulder section (6; 6a, 6b), the inclined protrusion (62) of the first attachment elements (7a) is pushed into the gap (73) while the shoulder section is at an inclined angle relative to the basic back section's plane in such a way that the rod (72) finds the gutter (63) of the protrusion (62) and is supported therein, which is followed by pivoting the shoulder section (6) from the inclined angle to a position coplanar with the basic back section (4) and the middle back section (5) with the rod (72) constituting a pivoting axis, whereby the protrusion (62) is wedged and clamped between the frame portion (71; 711) and the rod (72) and maintains the shoulder panel (6; 6a, 6b) locked to the side (40; 40a, 40b) of the basic back section (4), and wherein, in its releasing process, the shoulder section (6; 6a, 6b) is first pivoted to an inclined angle downward from a plane of the basic back section (4) and the middle back section (5), thus enabling the protrusion (62) to be released from the clamping of the frame portion (71; 711) and the rod (72), after which the shoulder section (6; 6a, 6b) is capable of being pulled out of the gap (73) and removed from the basic back section (4). |
