Definitions

  • the invention relates to a surgical utensil in the form of a gas supply device for supplying gas in the region of a temporarily opened by surgical intervention point of a human or animal body, with a gas supply line which is connectable to a gas source , and a gas outlet region with at least one gas outlet opening, preferably a plurality of gas outlet openings.
  • Such a device is known from AT394075T.
  • the purpose of such a device is to form a protective atmosphere in the area of an opened body site, which keeps non-sterilized air of the operating room away from the surgical site, whereby infections can be prevented.
  • gases such as carbon dioxide, oxygen, nitrogen, sterilized air-containing gases, or other medical gases. Medicines and / or narcotic drugs may be added.
  • a disadvantage of the device disclosed in AT394075T is that the staff working on the operating table can not check whether gas is flowing into the area of the opened body site or not. If at all, a gas flow can be determined indirectly only via a pressure gauge, which may be present on the gas cylinder. However, the gas cylinder is regularly in the operating room in the offside and is not seen by operating on the operating table staff. Interruptions or a complete failure of the gas flow can therefore not be detected and pose a threat to the patient.
  • the object of the present invention is to provide a gas supply device which does not have this disadvantage and allows the surgeon or assistant at any time to convince himself of an existing gas flow or to establish immediately if the gas flow is interrupted.
  • This control option should be available to the surgeon or assistant even if he can not move away from the operating table.
  • This object is achieved with a gas supply device mentioned above in that the gas supply device has a gas flow indicator for making a gas flow detectable by the gas supply device.
  • the gas flow or the presence of a gas flow can also be controlled by the position of the operating personnel, since the gas supply device itself has a gas flow indicator.
  • the invention thus ensures that the gas flow can be controlled at any time and consequently the surgical site is reliably and sufficiently supplied with gas.
  • Carbon dioxide, oxygen, nitrogen, sterilized air containing gases or other medical gases can be used as gases.
  • Medicines and / or narcotics may be added to the gas.
  • the visualization is a visualization of the gas flow, however, it could alternatively or additionally be acoustically identifiable, e.g. when a ball constantly strikes against a wall of the gas supply by the gas flow.
  • the gas flow indicator is arranged in the interior of the gas supply device, wherein the gas supply device is at least partially transparent at least in the area of the gas flow indicator.
  • the gas flow indicator is protected from external influences in the volume flowed through by the gas and at the same time is visible from the outside.
  • the gas flow indicator is arranged in the region of the gas outlet region.
  • the gas outlet region is to be understood as that end region of the gas supply device which is opposite to the end of the gas supply device which can be connected to the gas source.
  • the gas flow is made visible to the surgeon or assistant directly at the place of use, ie in the region of the opened body site, and thus in his immediate field of vision.
  • the gas flow indicator in the region of the gas supply line, ie as part of the gas supply line, so that the gas flow can also be seen by assistants who are slightly away from the opened body site.
  • the gas supply device has a housing into which the gas supply line opens, wherein particularly preferably the at least one gas outlet opening is formed in the wall of the housing and the gas flow indicator is arranged within the housing.
  • the formation of a housing which differs from the gas supply line in the mold can make the actual gas outlet area more easily locatable to the personnel; on the other hand, the housing can be adapted to the shape of the gas flow indicator used.
  • the housing is detachably formed by the gas supply line to provide access to the gas flow indicator or to remove the gas flow indicator, if stored by the housing, together with the housing.
  • the housing has, at least in sections, a larger cross-section than the gas supply line, whereby larger, e.g. from the outside more visible designs can be used for the gas flow indicator.
  • the cross-section of the housing decreases in the direction of the side facing away from the junction of the gas supply line and gas outlet openings are provided in this querroughsabigadem region of the housing.
  • the emerging (and not visible) gas stream can be directed more targeted to the opened body site.
  • the housing is egg-shaped or spherical. This promotes the reduction of turbulence in the gas outlet and allows for special designs of the gas flow indicator.
  • the gas flow indicator is arranged in an end region of the gas supply line. It is that end region of the gas supply line, which faces the region of the gas outlet region, whereby also the Recognizability of a gas flow in the immediate vicinity of the site is guaranteed.
  • the gas flow indicator is formed from at least one, movably mounted within the Gaszu211 adopted and displaceable by the gas flow in motion movement element.
  • such devices can be made particularly simple and inexpensive.
  • the moving element is preferably a rotatable element mounted rotatably within the gas supply device, such as a turbine or an impeller.

  • the moving element is preferably a thread or a flag fastened at one end within the gas supply device. This (r) is moved or streamlined in the gas stream. Preferably, at least a portion of the moving element is arranged at the level of the at least one gas outlet opening. As a result, the gas flow is detected immediately before the gas outlet. In addition, the moving element ensures a reliable mixing in case of several added gas components. In addition, turbulences of the exiting gas are minimized, whereby a possible laminar gas supply takes place without (turbulent) mixing with the non-sterilized ambient air.

  • the bendable and shaping wire allows by bending the specification of a desired course of the gas supply.
