Definitions
- the invention relates to a spray probe for the application of flowable two-component substances, in particular a two-component medical adhesive, such as, for example, a fibrinogen-thrombin tissue adhesive (fibrin sealant).
- a two-component medical adhesive such as, for example, a fibrinogen-thrombin tissue adhesive (fibrin sealant).
- the spray probe should have a simple construction.
- the invention relates to a spray probe for the application of flowable two-component substances, in particular a two-component medical adhesive comprising a flexible or substantially rigid multi-lumen tube with a plurality of separate lumens along the multi-lumen tube, which at one end of the multi-lumen tube, the sprayer, each open for himself and are connected at its other end, the supply end, with separate connections for the supply of the substance components and compressed gas.
- the multi-lumen tube has a cladding tube and arranged in the cladding partitions, in the cladding tube at least at the spray end in a located approximately in the middle of the cladding tube cross-sectional area two adjacent lumens each for one of the two components and substance Divide a running on both sides of the cross-sectional area of the substance lumens lumen region for the compressed gas, wherein the total clear cross-sectional area of the gas-lumen region is greater than the clear cross-sectional area of the two substance lumens together.
- the pressurized gas nebulizing the two substance components, which is preferably carbon dioxide gas, emerges symmetrically on both sides of the outlet region of the substance components determined by the two substance lumens. This ensures an improved turbulence of the substance components. Since the available for the supply of compressed gas clear cross-sectional area of the gas-lumen region is greater than the clear cross-sectional area of the two substance lumens together, the spray end of the multi-lumen tube for the vaporizing the substance components sufficient compressed gas volume can be supplied without the exit velocity of the gas excessively to have to increase.
- a spray probe is particularly suitable for micro-invasive use, for example in laparoscopy or in conjunction with an endoscope.
- the two substance lumens extend at least in the region of the spray end substantially over the entire width of the cladding tube and divide two gas lumens from each other, whose
- Cross-sectional area together is greater than the cross-sectional area of the two
- the two substance lumens run around at least in the region of the spray end substantially at a distance from the inner jacket of the cladding tube.
- the substance lumina are expediently abutting one another in the region of the spray end or are firmly connected to one another and are supported at the distance from the spray end either directly or via webs or the like on the cladding tube.
- the two gas lumens are completely surrounded by the compressed gas. In this way, a narrow spray cone with a substantially circular base cross-section can be achieved.
- the inner shell of the cladding tube has at least one helical groove and / or helical rib at least in the region of the spray end, which gives the compressed gas stream a twist.
- Several helical grooves or helical ribs can be arranged in the manner of a multi-start helix.
- the cladding tube preferably has a circular cross section and the two substance lumina are expediently next to one another at least in the area of the spray end on a diameter plane of the cladding tube.
- the substance lumens can likewise have a circular cross-section, which has the advantage in the case of circular partitions that the gas lumens comprise the two substance lumens over a comparatively large circumferential length, which is flushed with pressurized gas at the end of the spray.
- the substance lumens Both sides of the diameter plane of the cladding tube by mutually parallel partitions of the gas lumens and by a partition extending transversely between the partitions are separated from each other.
- the divider is for simplicity, designed as a right angle to the partitions extending plate-shaped web, but may also have any other shape, for example, be bent or inclined to the partitions.
- the divider extends centrally between the partitions and separates substance lumens with approximately equal cross-sectional areas. It is understood that the cross-sectional areas of the substance lumina both here and in the previously explained variants can also be chosen to be of different sizes in order to adapt them in this way possibly different flow properties of the two substance components.
- further partition wall may be provided which separates the two substance lumens from each other.
- the substance lumens and the cladding tube at the spray end of the multi-lumen tube open substantially in a common axis-normal plane.
- the width of the spray cone may also be affected when the cladding tube and / or each substance lumen at the spray end of the multi-lumen tube forms a muzzle cone widening towards the spray end of its inner jacket.
- the cladding tube and the partition walls arranged in the cladding tube expediently have substantially the same axial cross-sectional shape over the entire longitudinal extension of the multi-lumen tube. This simplifies the production of the spray probe.
- the cladding tube and the two substance lumens can in this case by mutually separate tubes, in particular metal tubes be formed.
- the cladding is preferably made of metal, such as stainless steel, since the spray probe in this embodiment is very rigid in practice desirable manner. If necessary, the two substance lumens can be made of plastic to reduce costs.
- the cladding tube and the two substance lumens can also be formed together by a extruded profile tube.
- the spray properties of the spray probe can be influenced if the cladding tube near the spray end has at least one passage opening for gas in its wall delimiting the gas-lumen region.
- the size and / or inclination of this passage opening relative to the longitudinal axis of the cladding tube, the size of the misting droplets and / or the width and shape of the spray cone can be influenced. If the outlet direction of the passage opening directed towards the spray end, a portion of the gas flow supplied through the cladding tube is directed from the outside against the spray cone, which is thereby narrower. Overall, a thinner spray can be achieved in this way.
- the passage opening flows from radially inward to radially outward, as viewed against the exit direction of the spray cone, then the gas flow in the jacket tube sucks in additional gas from the environment. This leads to a finer atomization and due to the increased turbulence to a wider spray cone.
- the passage opening is designed as a symmetrical slot extending in a plane inclined obliquely to the axis of the cladding tube and symmetrical with respect to a plane of axial longitudinal section of the cladding tube running at right angles to this plane.
- a slot can be easily produced by oblique sawing the cladding tube and has the advantage that it can influence the spray cone on a large part of its circumference.
- a plurality of slots are expediently distributed uniformly in the circumferential direction, but for the sake of simplicity only two diametrically opposite slots.
- the narrowest distance between the spray end and the slot is less than 5 mm, in particular less than 3 mm, in order to achieve a sufficient influence on the spray cone.
- the plane containing the slot should be inclined by less than 45 °, preferably by about 30 °, against the AxiallCodesitessbene.
- the passage openings or slots can be incorporated directly into the otherwise integrally formed cladding tube.
- the spray end of the cladding tube can also be designed as a replaceable head which contains the passage openings or slots.
- the two substance lumens are connected at the feed end via a flexible tube with one of the substance connections, wherein the two substance connections are mounted with parallel connection direction side by side on a split holder, the holder halves in the direction in the substance connections are arranged side by side, are guided relative to each other slidably together.
- a flexible tube connecting the substance lumens with the substance connections can be made elastically resilient.
- the substance components are comparatively viscous substances, which due to the relatively narrow substance lumens
- Spraying need to be pushed out. As far as the delivery pressure manually over
- Piston spraying is generated, comparatively large pressing forces manually be applied to the syringe.
- Another disadvantage of conventional spray probes is that the substance lumens form a dead volume for the substance components, which can no longer be ejected at the stroke end of the syringe and is lost.
- these disadvantages can be avoided if, in the area of the feed end, between each substance lumen and its substance connection, a one-way valve which opens toward the substance connection and opens toward the spray end is arranged in the substance supply path and if in the region of the feed end between the one-way valve and the spray end, a supply path for pressurized gas opens into the substance supply path.
- the compressed gas injected into the substance supply path conveys the substance components to the spray end independently of the supply of the substance components at the substance connections.
- the substance components can be inserted in portions, for example from piston syringes into the substance lumens, where they are conveyed from the compressed gas to the spray end and blown out there.
- the above-described aspect of the invention can also be used with other spray probes than the spray probe explained above, in particular also with spray probes, which mix and atomize the two substance components without compressed gas supplied separately until the end of spraying, for example in a mixing nozzle.
- the aspect thus has independent inventive significance.
- the substance connection of each substance supply path, together with the one-way valve and a compressed gas connection for the compressed gas to be introduced into the substance supply path, is combined to form a structural unit.
- the pressurized gas which promotes the substance components in the substance lumina improves the mixing and atomization at the end of the spray. If appropriate
- Dimensioning of the gas flow can also be dispensed with bringing compressed gas separately to the spraying end, so that the two substance Components are mixed and atomized, for example, in a mixing nozzle at the spray end.
- the pressurized gas which promotes the two substance lumens during application spreads the substance lumens after the application, so that they do not clog in application pauses.
- the compressed gas is supplied during the application of the two-component substance to the substance supplying lumens at a first pressure and during an application pause with a second pressure which is lower than the first pressure. Since in this way the substance lumens are continuously purged with compressed gas, the clogging is particularly reliably prevented.
- the first pressure is preferably between 1.5 and 2.5 bar, while the second pressure is between 0.2 and 0.8 bar, in particular approximately 0.5 bar.
- the two substance components can continuously or in portions in the continuously flowing in turn
- Compressed gas are introduced.

- the cladding tube 3 as well as the tubes 5, 7 which extend essentially over the entire length of the multi-lumen tube 1 have a circular cross-section.
- the tubes 5, 7 have an outer diameter which is approximately equal to half the inner diameter of the cladding tube 3. Without being connected to the cladding tube 3 along its length, the two tubes 5, 7 therefore orient themselves next to each other in a diameter plane of the cladding tube 3.

- the multi-lumen tube 1 is rigid and the cladding tube and the tubes 5, 7 are made of metal.
- the cladding tube 3 and / or the tubes 5, 7 may be made of plastic and in particular may also be flexible, but metal, in particular stainless steel for the cladding tube 3 is preferred, even if the tubes 5, 7 of the production costs because of plastic.

- Substance components supplied via the substance connections 19b, 21b can thus pass to the spray end.
- the compressed gas fed to the connections 59, 61 promotes the delivery of the substance components through the comparatively narrow substance lumens and is able to blow off dead volumes from the substance lumens.

- the slots 73e are in the range the gas lumens bounded by the cladding tube 3e, however, define gas passage openings which, due to the gas flowing in the gas lumens, suck additional gas from the environment, which exits at the spray end 15d.
- This design of the slots 73e causes a finer atomization of the substance components to be sprayed and a widening of the spray cone.
- the configuration of the slots 73e completely corresponds to the exemplary embodiment of FIGS. 6 and 7, and here too more than two of these slots may be provided at different distances from the spray end 15e.
