Title: Multipositional surgical operating table with electric drives - has virtual longitudinal rotation axis and adjustable electrically controlled head support
Inventor: BUFFET JEAN-MICHEL
IPC: A61G13/12
Filed: 1982-02-22
Abstract: The operating table has a stand, and a rectangular table which is mounted such that it is mobile w.r.t. the stand and can make a vertical translational movement, and a pivoting movement around a horizontal axis transversal w.r.t. the longitudinal axis of the table. It can also make a rotational movement around an axis parallel to the longitudinal axis of the table. The longitudinal rotation axis is virtual and situated above the plane of the table. Coupling between the stand and the table is via a support chassis whose longitudinal axis extends parallel to that of the table. An auxiliary chassis is fixed near one end of the table having a circular roller-track which together with a longitudinal shaft mounted at the other end of the table, defines the longitudinal rotation axis position. A head-support is pivotally mounted on one end of the table, its angular position about the transverse axis being controlled by an electric actuator. When the table is in the desired position it is blocked by a brake. A second table above the first enables the patient to be supported in any desired position to facilitate surgical operations.
