Description

The display element 92 allows the user to determine the rotational position of the rotational element 70 in order to determine the bending surface as a bending parameter. The following are the features of the technology disclosed herein. (Item 1) In particular, a medical bending system for bending an object (14) to be bent, which is a rod (18), At least one object to be bent (14) and A bending device (12) capable of bending the object (14) to be bent, A navigation device (16) having a detection unit (78) and a data processing unit (76), Equipped with, The object to be bent (14) and the bending device (12) are provided with a plurality of markings (22, 40, 42, 62, 72) arranged or formed on their respective surfaces (24, 44) and optically detectable by the detection unit (78), The bending system is characterized in that the data processing unit (76) is configured to determine at least one bending parameter during a bending operation based on information from the detection unit (78) regarding the detected marking. (Item 2) The bending system according to item 1, characterized in that the plurality of markings (22, 40, 42, 62, 64, 72) are integrated or formed on the surface (24, 44) of the object to be bent (14) and/or the bending device (12), preferably by anodizing, shape-changing exposure, or water-printing coating. (Item 3) The bending system according to item 1 or 2, characterized in that the plurality of markings are formed separately from the object to be bent (14) and/or the bending device (12) and connected thereto. (Item 4) The bending system according to any one of items 1 to 3, characterized in that the navigation device (16) is an integrated navigation device (16) comprising the detection unit (78), the data processing unit (76), and the instruction unit (82), or comprises the same, and in particular, the navigation device (16) is a smartphone (74), a tablet computer, or a head-mounted device (HMD), or comprises the same. (Item 5) The bending system according to any one of items 1 to 4, characterized in that the desired shape of the object to be bent (14) can be determined by the data processing device (76) based on data from the sensor unit of the navigation device (16), so that the object to be bent (14) can connect a plurality of connecting elements arranged in a predetermined relative positional relationship. (Item 6) A predetermined desired shape of the object to be bent (14) is stored in the memory unit (80) of the navigation device (16), and instructions are given to the user regarding at least one of the following: Instructions for operating the bending machine (12) are provided, wherein the value of at least one bending parameter is determined, the actual shape of the object to be bent (14) is determined based on that value, and compared with the desired shape, and preferably, instructions are provided when the value of at least one bending parameter has a desired value or is different from that value. - Instructions for selecting an object (14) to be bent from a set of multiple available objects (14) to be bent. The bending system according to item 5, characterized in that it outputs to the instruction unit (82) of the navigation device (16). (Item 7) The bending system according to item 6, characterized in that the plurality of markings are detected by the detection unit (78) during the bending operation, and instructions to the user are provided by the data processing unit (76) in relation to the actual shape of the object to be bent (14), in particular the actual value of at least one bending parameter, and a desired value of at least one bending parameter. (Item 8) The bending system according to any one of items 1 to 7, characterized in that the object to be bent (14) comprises a plurality of markings (22) in the form of a surrounding ring (26) arranged on the object to be bent (14) at a distance from each other in the longitudinal direction of the object to be bent (14). (Item 9) The bending device (12) has a plurality of markings (40, 42, 62, 64, 72) in at least one of the following forms, namely, - Multiple markings (40, 42) extending flat on the surface of the branch portions (36, 38) of the bending device (12), - At least one marking (72) on a rotational receiver that holds the object to be bent (14) on the bending device (12) so that it can rotate around an axis (68), - At least one marking (62, 64) on the support element (54) for positioning the object (14) to be bent during the bending operation, A bending system according to any one of items 1 to 8, characterized by comprising: (Item 10) The bending system according to any one of items 1 to 9, characterized in that the data processing unit (76) uses at least one marking on the bending device (12) to define a reference coordinate system in a space (12) in which the position of the object to be bent (14) relative to the bending device (12) can be determined. (Item 11) Based on the multiple markings (22, 40, 42, 62, 64, 72) det
