Abstract

A cleaning and / or drying device 1 for human and veterinary applications, with which a sterile compressed gas jet can be directed by means of substantially one-handed guidance to a point to be cleaned and / or dried and controlled by fingering with respect to exposure time and gas volume comprises a handpiece 2, in which a controllable by an actuator 3 valve 4 is arranged, whose output side is connected to a nozzle 5 fixed to the handpiece 2 in gas-tight connection, and the input side of the valve 4 is connectable to at least one removable in the handpiece 2 replaceable compressed gas tank 7.

Description

  • The The invention relates to a cleaning and / or drying device for use in human and veterinary medicine, with which z. B. wounds cleaned before further treatment by a compressed gas jet or for the Implantation of endoprostheses prepared bone areas of loose tissue particles, bone chips, Blood and body fluids as well as previously used rinsing fluids can be freed and dried. This is the one nozzle outgoing compressed gas jet through essentially one-handed leadership directed to be cleaned and / or to be dried place and the Gas jet as required with respect to exposure time and gas volume by fingering controlled.
  • Devices with the aforementioned function are z. B. off US Pat. No. 5,037,437 B1 known. They include a pistol-shaped handling device, which is connected via a compressed gas hose with a central compressed gas supply or a compressed gas cylinder. The mouth of the gun-shaped handling device is designed as a nozzle for an outgoing compressed gas jet, and by means of a trigger to be operated with the forefinger, the gas jet can be controlled as required with respect to exposure time and gas volume. The surgeon directed by essentially one-handed guidance the gas jet to be cleaned and / or to be dried place and blows the Verun cleanings such. As loose tissue particles, bone chips and liquids aside, the exposed tissue is dried by the dry gas jet simultaneously with the elimination of the impurities or after. In this way, z. B. Prepare prepared bone stock excellent for receiving endoprostheses. By taking place immediately before the onset of the endoprosthesis sterile cleaning and drying the best conditions for a good bonding of the bone cement used for the attachment of the prosthesis and for a good connection of the endoprosthesis with the bone and thus for their long-term tight fit in the bone stock created.
  • In addition to the above-described advantages in the supply of open tissue sections in human and veterinary medicine, the known pistol-shaped cleaning and drying devices to which the compressed gas is supplied from central compressed gas supplies or compressed gas cylinders via compressed gas hoses, but also considerable disadvantages:
    The guarantee of sterility is extremely problematic and costly when using central compressed gas supplies or gas cylinders and the supply of compressed gas to the cleaning and drying device via compressed gas hoses. Although compressed gas bottles are commercially available with sterile content, ensuring the sterility of the bottles themselves and their connections z. B. during transport is almost impossible with reasonable effort. The handling of non-sterile bottles in their connection with the sterile supply hoses or with the usually non-sterile lines of central pressurized gas supplies is so complicated that the z. B. known from the aforementioned US patent device has been virtually never used. Against the application of this known device also speaks that the feed hoses are extremely hindering for a free manipulation of the surgeon. In addition, the hoses must be disposed of or sterilized after each use, which causes an unreasonable expense.
  • Of the The invention is therefore based on the object, a cleaning and / or Drying device for human and veterinary To create applications with which a sterile compressed gas jet by one-handed guide targeted and precise directed to a specific location to be cleaned and / or dried can be, and what a disability-free work at relatively low labor and cost allows.
  • The The object is achieved by the characterizing features of claim 1 solved. advantageous embodiments the invention form the characterizing features of the dependent claims 2 to 9th
  • The invention will be described below with reference to a preferred embodiment in conjunction with the single 1 be explained in more detail.
  • 1 shows a cleaning and drying device according to the invention 1 in a schematic cross-sectional view.
  • The cleaning and drying device 1 includes a handpiece 2 in which one by an actuator 3 controllable valve 4 is arranged. The exit side 9 of the valve 4 stands with a handpiece 2 attached nozzle 5 in gas-tight connection. According to the invention, the input side 10 of the valve 4 with at least one in a chamber 6 of the handpiece 2 removable replaceable compressed gas tank 7 connectable.
  • In 1 is the input side 10 of the valve 4 shown as a hollow mandrel, with which when inserting the cartridge 7 in the chamber 6 a cartridge opening sealing closure, z. As a flat plug made of aluminum or plastic, is pierced and in this way the gas stored in the cartridge via the channel of the hollow mandrel on the input side 10 of the valve 4 is exhaustible. The valve is in 1 schematically as a under bias of the compression spring 11 standing two-sided lever 3 shown, the short lever arm of the spring 11 presses on the top of the hollow spike channel and prevents outflow of the compressed gas until the operator by fingering the long lever arm of the lever 3 against the bias of the compression spring 11 raises the short lever arm and thereby the outflow of the compressed gas from the hollow mandrel channel and the forwarding via the valve outlet 9 and the nozzle 5 allows. By the finger operation on the long lever arm of the lever 3 Both the discharge duration of the compressed gas and the outflow volume can be sensitively controlled by the surgeon as required.
  • This in 1 illustrated valve 4 is merely the schematic representation of one possible embodiment, and this may be replaced by any other form of manually operable valve.
  • Preferably, that is in the chamber 6 of the handpiece 2 Recordable and replaceable compressed gas tanks 7 a compressed gas cartridge. Such compressed gas cartridges, which z. B. made of metal, preferably made of stainless steel, are filled with CO 2 commercially available and are used for the preparation of carbonated water or for expelling beer and other carbonated beverages from canister-like containers. Although this compressed gas used for food has a high degree of purity, but is not sterile in the medical sense. The sterilization of such compressed gas cartridges and their contents can be done relatively easily by irradiation of the cartridge with gamma rays. The thus achieved sterilization can be achieved by immediately subsequent packaging of the cartridges, z. B. by gas-tight welding under sterile conditions, are maintained for transport to the user in a simple manner. The devices 1 themselves, like other medical devices, can be thermally sterilized locally in the usual way.
  • The nozzle 5 is z. B. by screwing or by a bayonet connection with the handpiece 2 in gas-tight connection, so that, over the valve 4 controlled, from the cartridge 7 escaping compressed gas lossless and without secondary flows through the nozzle reaches the application site.
  • Preferably, the nozzles are interchangeable, ie they can from the handpiece 2 be solved and replaced by other forms of nozzles, so that each roof use nozzles with different beam directions, opening widths, etc. can be used.
  • It is possible, too, that the nozzles even in terms of their opening width, their beam direction, etc. can be adjusted so that one for the application suitable beam direction, nozzle opening width etc. can be adjusted without requiring a change of nozzle is.
  • As already mentioned, the control of the compressed gas jet takes place with regard to exposure time and gas volume by finger actuation. The surgeon can by means of the actuator 3 the valve 4 open and close as required and enlarge or reduce the outflowing compressed gas volume. This makes it possible that the compressed gas jet used for cleaning and / or drying by means of one-hand operation not only targeted and precisely directed to the desired location but also its intensity can be adapted to the requirements.
  • at the release of the pressurized gas from the nozzle occurs a cool down of the gas, which in any case was perceived by the patient as pleasant becomes.
  • The inventive cleaning and / or Drying devices are compared to the known devices much easier to handle. in addition, and this falls in comparison to the known devices to which the compressed gas is supplied via hoses, Of particular importance is the sterility of the device and the compressed gas ensured in a simple manner become.
