Arrangement and method for connecting an accessory part to an operating table

摘要

An accessory part to be connected to an operating table has a connecting element (12, 16) and a component part of the operating table has a receiving area (14) for receiving at least an area of the connecting element (12, 16). An engagement element (22, 24) projects laterally from the connecting element (12, 16). The receiving area (14) has at least one guideway (18, 20) with which the engagement element (22, 24) engages during insertion of at least an area of the connecting element (12, 16) into the receiving area (14). When deformed, an elastically deformable element (52) exerts a force on the engagement element (22, 24). By the force exerted on the engagement element (22, 24) and by the course of the guideway (18, 20) a force (FA) is exerted in the direction of insertion (P2) on the connecting element (12, 16) when the accessory part and the operating table are connected.

主权项

1. An arrangement for connecting an accessory part to an operating table, the arrangement comprising:
a connecting element adapted to be connected to the accessory part, the connecting element having a substantially cylindrical portion with a hollow interior, at least one opening into the hollow interior being formed in a circumferential surface of the cylindrical portion; an engagement element having an inner cylinder rotationally disposed within the hollow interior of the connecting element and having at least one cylindrical pin that projects radially outward from the inner cylinder and through the at least one opening of the connecting element; an elastically deformable element disposed within the hollow interior of the connecting element, the elastically deformable element resisting rotation of the engagement element within the hollow interior of the connecting element; a component part having a receiving are for receiving at least and area of the substantially cylindrical portion of the connecting element, the component part adapted to be connected to the operating table; wherein the receiving are has a guideway with which the at least one cylindrical pin of the engagement element engages during insertion of the at least an area of the substantially cylindrical portion of the connecting element into the receiving area, wherein the guideway has a rising area and a falling area; wherein upon insertion of the connecting element into the receiving area the engagement element is rotated within the hollow interior against the force of the elastically deformable element by engagement of the at least one cylindrical pin with the rising area of the guideway, and wherein the elastically deformable element, when deformed, exerts a force on the engagement element, wherein by means of the force exerted on the engagement element and by the course of the guideway, when the at least one cylindrical pin of the engagement element engages the falling area of the guideway, a force FA acts in the direction of insertion (P2) on the connecting element when the accessory part and the operating table are connected.
