The current invention refers to the exoskeleton structure system inside the hospital, which provides a system for the lower limbs. Its characteristics are that it moves through an axis of heart, through the degree of freedom, the three main links of each axis interact. Allows special surgical postures to support medical staff, as well as cycling on the patient's limbs to avoid passage through porous ulcers, or a rehabilitation process, including: a first system, low end, A lower end (1.1) consisting of a bracket,a. Rotate through the lower positioning element at the hip level (3.5)；There is a lower motion system (1.2),It allows a bicycle movement, a secondary system, for the upper limbs, consisting of a catheter (2.4),a. Rotation by positioning element (3.5)；1. There is an upper power system (2.2) to provide the upper members with the main bicycle movement； there is a No. 3 system for logs and heads, consisting of log supports (3.1)；It has a driving factor of log and head (3.2), which produces the main bicycle movement for log and head； there is also a non-4 system, which can be selected, for the exoskeleton to locate through the rotation of element (4.1), which is fixed on the platform of element (4.2),3. Position it in any of the three main axes (x, z)；It has transport elements for exoskeletons (4.2).La presente invencion, se refiere a un sistema estructural exoesqueleto intrahospitalario del tipo que presenta un sistema para la extremidad inferior, caracterizado porque genera movimientos cardioides en un eje, mediante un grado de libertad, interactuando tres eslabones principales por cada extremidad； permitiendo posturas especificas para procesos quirurgicos en apoyo al personal medico, asi como movimientos ciclicos sobre extremidades del paciente para evitarle la ulcera por decubito o para un proceso de rehabilitacion, comprendiendo: un Sistema No 1, para extremidades inferiores, conformado por una pieza de soporte para una extremidad inferior (1.1), la cual gir
