Definitions

  • the present invention relates to operating tables of universal use, especially adapted for different types of surgery.
  • Surgical operations are commonly made on operating tables which essentially comprise a support column with a base platform laid on the ground and supporting an operating plane member on which the patient to be operated lies.
  • the table must be provided with a surface supporting the patient, said surface being adaptable to all body sizes, usable for al! types of surgery and, overall, being displaceable by the operator without effort and without hindering the action field of operators and surgeons.
  • the removal of the plane members from the column or from the plane/column system can be performed from one side or from both, e.g. along the direction head to feet or laterally.
  • Operating tables of the known type are not provided with memory apt to deliver statistical data concerning the use of the table, manoeuvring errors that occurred in a certain period of time, the quantity of operations, alarms, breakdowns and similar events.
  • Supports that hold the patient's feet are not transparent to radio signals even if they are can be displaced by translating motion and spread for giving an easier access to users. On the contrary if they are transparent to radio signals, they cannot be translated and spread.
  • the protection elongating bellows being rich in folds where dust and dirt easily accumulate, make difficult cleaning and sterilisation of said table.
  • the tables of the known types are provided with joints and linkages. They produce clearances that can give place origin to dangerous oscillations of the table.
  • the main purpose of the present invention is to eliminate the above mentioned disadvantages by means of an operating table allowing patients to be placed on a stretcher from all four sides.
  • Another purpose of the invention is to provide an operating table with variable velocity apt to produce more or less rapid movements depending on the type of surgery to be carried out.
  • Another purpose of the invention is to provide an operating table allowing positioning of patients in extreme positions, e.g. in very high or very low positions or with very high inclinations of head or feet side.
  • Another purpose of the invention is to provide an operating table having a diagnostic system allowing to give information to users on the state of the system, so as to help said users to correct the possible manoeuvre errors.
  • Another purpose of the invention is to provide an operating table allowing the display of multilingual messages, easily accessible to operators.
  • Another purpose of the invention is to provide an operating table allowing storage in memory of the most recurrent positions so as to be able to call them back at any moment and rapidly.
  • Another purpose of the invention is to provide an operating table that can provide statistical data on its state of usage and reliability.
  • Another purpose of the invention is to provide an operating table that can give operators information not visible on digital displays.
  • Another purpose of the invention is to provide an operating table where the connection between table and supporting column allows power supply.
  • Another purpose of the invention is to provide an operating table allowing spreading and widening of the feet supporting sections in a way totally transparent to radio signals.
  • Yet another important purpose of the invention is to provide an operating table with high stiffness and stability.
  • an operating table in accordance with the main claim, comprising a support column with a support ground platform, an operating plane member adapted to support the patient to be operated and means for removably connecting said column to said plane member, wherein said column defines a longitudinal symmetry plane, characterised in that said removable connection means comprise mechanical coupling means with complementarily shaped profiles tapered towards the upper side thereof, to which electronic means for the transmission of information and electrical means for power transmission are associated.
  • the mechanical coupling means connecting the plane member to the column can advantageously transmit both power supply and information, independently from the position or inclination of the operating plane member, without any danger of multifunctioning interference due to dirt penetration.
  • the table according to the invention allows advantageously more flexibility for the users, for the following reasons:
  • Yet another advantage is provided by the lack of joints and linkages which allows operating tables according to the invention to reach higher performances, compared to operating tables of the known kind, by avoiding mechanical clearances.
