  • the need for human intervention determines a series of inconveniences of various kinds that can affect the safety of the operators at work, the correctness and effectiveness of the performed treatments, the execution times, the need to use particularly specialized personnel, the costs of processing, etc.
  • a drawback relates to the movement of the instruments between the different stations, often with the need to introduce the instruments into the chambers set up for one or more treatment phases at the stations of the plant.
  • Another drawback relates to the different configuration that the instruments must assume according to the treatment phase to which they are subjected, in particular as a function of the conformation of the station chamber dedicated to this treatment phase.
  • US2019/201571 e US5893618 describe containers for surgical instruments that have to be wound by a further coating for obtaining a hermetic closure.

  • the capsule allows an extremely significant increase in the safety relating to the sterility of sterilized instruments thanks to the use of the same capsules as chambers within which the various phases of the washing / disinfection / sterilization treatment take place; the capsule allows to optimize the times and resources necessary for the entire washing / disinfection / sterilization treatment, as well as for the final storage thanks to an automated management of the movement of the instruments between the various processing stations and any possible waiting stations; the capsule allows the instruments to be housed in a configuration in which the same instruments can be placed, within containing grids, on at least two different horizontal planes for the treatment, as well as stored and used after treatment, with the possibility of being removed from any of these planes without the need to move the instruments placed on a different plane; it is also possible to move the containers between the different stations using an autonomous vehicle, preferably provided with a device for reading and writing codes interacting with corresponding identification elements (for example of the radio frequency or RFID type) present on the

  • a first support plane (67) is provided on the second portion (6’ ) on which a first video camera (66) fixed to a horizontal crosspiece (65) of the second portion (6’ ) acts.
  • the first camera (66) is able to scan what is placed on the support plane (67).
  • first portion (6) there is a second support plane (600) on which a second video camera (69) is acting, fixed to a pair of horizontal crosspieces (68) of the first portion (6).
  • the second camera (69) is able to scan what is placed on the second support plane (600).
  • the capsule (2) arrived at the station (C) is placed on the appendix (60) and is opened, moving the instruments contained therein, for example an entire drawer (27), on the support plane (67).
  • the first camera (66) scans the instruments present on the support plane (67) to provide an indication of their nature and arrangement.
  • the data detected by the first video camera (66) are used by the articulated arm (63) to pick up the instruments by means of the gripping member (64); in practice, the scan performed by the first video camera (66) allows the gripping member (64) to pick up an instrument knowing where the instrument is on the plane (67) as well as the type of instrument picked up. Therefore, the gripping member (64) can be moved to take a specific instrument and grasps the instrument at a point compatible with the shape of the instrument itself, or with the relative weight distribution on it.
  • the instrument taken from the gripping member (64) is placed on the second support plane (600), where the second camera (69) scans the instrument and, comparing it with a series of sample images, is able to provide information relating to the correctness of the treatments carried out up to that point and on the state of wear of the examined instrument.
  • the second camera can perform two types of controls, for example of the type called “shape” and “color”.
  • the “shape” control allows to compare the actual shapes of the instrument under examination with a series of archived sample images to check, for example, the sharpness of a blade or the presence of dents to determine the state of wear of the instrument and therefore the functionality requirements of the same.
  • the “color” control thanks to a different transmission of the received light, allows to check for any residues and/or stains e therefore to control the previous washing operation.
  • the opening of the capsule (2) can be done manually, as can the arrangement of an instrument drawer (27) on the first support plane (67).
  • the remaining movement of the instruments is preferably performed by robotic means, in which the extensible portion (602) allows the base (601) and the articulated arm (63) supported by it to be moved vertically, while the articulation of the arm (63) allows to move the gripping member (64) freely between the various areas of the structure (6, 6’ ).
  • the sterilization phase is performed in the sterilization station (D), which consists of an autoclave apparatus in which the capsule (2) constitutes the sterilization chamber for the instruments.
  • the instruments therefore remain inside the capsule (2) in all stations of the plant, with the exception of the control station (C) in which the capsule (2) is temporarily opened for an accurate examination of the instruments.
  • the sterilization station (D) performs the sterilization of the inside and the outside of the capsule (2) and comprises a substantially parallelepiped support structure (8) which has an access portion (80) in correspondence with one of its minor vertical faces defined by two parallel horizontal guides (81).
  • the vehicle (3) can pass through said access portion (80) to arrange the capsule (2) to be treated in the station (D).
  • the instruments to be sterilized always remain inside the capsule (2) which, as previously mentioned, is therefore used as a sterilization chamber for the instruments.
  • a first conveyor (84) is provided which carries the capsule (2) inwards, until reaching an internal chamber (82) delimited by a door (84), beyond which a second conveyor (85) is provided and acts which carries the capsule (2) inside the internal chamber (82).
  • connectors (86) Inside the internal chamber (82) there are connectors (86) in a number corresponding to the accesses (24) provided on the capsule (2).
  • the connectors (86) are four like the accesses of the capsule (2), of which only two are visible in Figs.9F and 9G because they are arranged aligned in pairs.
  • each connector (86) is provided with a nozzle terminal (87) which can be coupled with the access (24) of the capsule (2).
  • the nozzle terminal (87) is connected to a relative supply duct (88) through which the fluids used for sterilization pass.
  • the conduit (88) can be used for saturated steam, for vacuum extraction, or introduction of external air, for example with the succession of air/vacuum pulsations in the final drying phase of the instruments
  • the access (24) is connected to the inside of the capsule (2) through an internal conduit (29) for the sterilization of the instruments and of the inside of the capsule itself.
  • the internal chamber (82) is equipped with a dispenser (800) connected to a supply line (89) to introduce flows of steam, steam, or air into the chamber (82), to hit the outer walls of the capsule (2) in the sterilization phase.
  • the references (802) and (803) of the station (D) schematically represent the means for dispensing and feeding the fluids used for sterilization.
  • the sterilization station (D) can be connected to the feeding systems of the fluids necessary for the treatment such as, for example, the centralized vacuum group (H) or the centralized steam group (S) mentioned in precedence.
  • the surveys carried out by the robotic means of the station (C) are sent to a central unit (not described or illustrated) which, being connected at least to the vehicles (3) as well as to the stations (A), (B), ( C) and (D), can be delegated to the activation and control of the washing, disinfection and sterilization phases in order to perform these operations automatically.
  • Means may also be provided for manual entry of commands (for example a keyboard) for programming the vehicles (3), the operating stations (A, B , C, D) and the central unit itself.
  • the invention relates to a container or capsule for the containment of surgical instruments in a sterilization treatment in which the washing, disinfection and sterilization of the surgical instruments is carried out.
