Definitions

  • the present invention relates, in general, to devices for protection against ionizing radiations for use in the medical field and, more specifically, the surgical field.
  • the invention relates to methods and systems for the protection of a healthcare professional, notably a surgeon, exposed to ionizing radiation, e.g. X- rays, while performing his professional activity.
  • Procedures involved in this issue may be of a therapeutic, diagnostic and/or surgical type, and related, for example, to the need for imaging a body district during an open surgery, laparoscopy or minimally invasive surgery in general.
  • imaging devices used for example those for intraoperative fluoroscopy, provide for limited emissions of ionizing radiation, it is required ensuring that the repeated exposure over time does not to lead to exceeding the safety limits established by law, for example in Directive 2013/59/Euratom.
  • glasses with protective lenses against ionizing radiations constrain, by their nature, the visual field of the user.
  • glasses have the disadvantage of discharging their weight upon the nasal septum and ears, giving rise to possible sensations of itching or pain that cannot be addressed while the operator is performing medical procedures, especially when the latter is wearing also a helmet and a protective hood.
  • several procedures, in particular surgical procedures can last very long over time.
  • the protection against ionizing radiation provided by a certain material is a function of the thickness of the material itself.
  • a pair of glasses intended to ensure a high level of protection must necessarily increase its weight, with a resultant greater occurrence of all aforementioned drawbacks.
  • the technical problem posed and solved by the present invention is therefore to provide a protection device which allows overcoming the aforementioned drawbacks with reference to the prior art.
  • the invention further provides a system according to claim 15, a kit according to claim 17 and a method according to claim 19.
  • Preferred features of the present invention are the subject of the dependent claims.
  • the present invention provides several remarkable advantages.
  • the main advantage lies in that the protection systems of the invention are directly connectable or connected, in a removable way where appropriate, to the structure of a protection helmet and to a medical garment, in this regard ensuring a perfect integration with the equipment of the surgeon, or healthcare professional in general, who wears them.
  • the proposed protection systems are more comfortable to wear than a known type of safety glasses, since there is lack of bars under the helmet, which may create discomfort, and it is avoided to discharge the glasses’ weight upon the operator's nose.
  • the protection systems of the invention precisely by virtue of the presence of a dedicated connection to the helmet or to a medical garment, provide greater guarantees for completely shielding the face and further ensure a broad and complete field of vision.
