  • an endoscopy unit consists of an optical unit used for imaging and a light source, usually implemented in optical waveguide technology, for illuminating the object under consideration.
  • the optical unit was conventionally removed from the corresponding body cavity and cleaned extracorporeally with, for example, warmed saline solution and reinserted into the corresponding body cavity through a trocar.
  • This is fundamentally time-consuming and involves an increased risk of complications, since during this time the operating area cannot be observed, the operating team is additionally burdened and the operating times are extended. This may result in poor surgical outcomes.
  • the laparoscopic operation has to be stopped and the conventional method continues with large body sections.
  • the problem underlying the present invention therefore generally consists in creating an optical cleaning device which cleans the optical unit in the body when necessary.

  • the angle of the current deflection device with respect to the optical plane can thus be realized for an optimal reflection of the gas and liquid flow onto the image entry surface. This offers a significant advantage in particular in the case of optical units which have a certain inclination with respect to the axis of symmetry of the endoscopy device.
  • a fastening device is integrally formed on the shell section. This is intended to achieve an additional clamping effect and to prevent the optical cleaning device from slipping on the endoscopy device housing.
  • the shell section is formed from an elastically deformable plastic. This results in low manufacturing costs on the one hand and no major disposal problem on the other.
  • the optical cleaning device can be attached as an attachment to differently dimensioned endoscopy devices, for example with different diameters. As a result, the existing endoscopy devices can continue to be used and high acquisition costs for new endoscopy devices including optics cleaning devices can be avoided.
  • the shell section partially encloses the outer circumference of the endoscopy device housing. This depends on the diameter of the corresponding endoscopy device.
  • the fastening device is designed as a spring clip or clip.

  • the fastening rail has plug connections connected to the flow channels at the distal end for a connection to the flow deflecting device, the flow deflecting device having through holes which are designed to conform to the plug connections and thus a gas and / or liquid flow through the flow channels to the flow deflecting device is ensured ,
  • the shell section together with the current deflecting device can have a smaller size and no bores in it are necessary for the formation of flow channels.
  • the flow is supplied via channels formed in the fastening rail.
  • the fastening rail can be mounted on or on the shell section on the endoscopy device housing by means of fastening elements.

  • the shell section and the fastening device are formed from materials approved in laparoscopic medicine.
  • the shell section and the fastening device are sterile packed and made from recyclable material. As the relevant facilities are used only once due to the risk of infection, attention should be paid to these circumstances.
