Definitions
- the invention relates to a method and a device for moistening a liquid-absorbing medical implant or graft made of essentially biological material.
- An implant is a piece of tissue or other material inserted into the (human) body that remains at least temporarily in the recipient body.
- Bone grafts are particularly suitable (human or bovine). It is also known in the prior art to remove particles from e.g. To use bone as a medical filler, e.g. in the dental field for filling extraction cavities. Filling materials of this type are also regularly rehydrated (ie moistened) before use, and the present invention is particularly suitable for this. If, according to the present invention, it is stated that the material should be "essentially biological", this means that the material has been obtained at least largely by another living being or also by the patient himself. However, the material may contain minor additives (up to a few percent, usually less than 10%) of non-biological, i.e. not contain material obtained in the manner mentioned above.
- the surgeon receives pieces of bone intended for transplantation in sterile packaging. These pieces of bone are brought into contact with a moistening agent, such as saline or plasma.
- the moistening agent can optionally also contain a medicament as an additive. This procedure for moistening implants or grafts is expensive. dig and takes time. It also usually requires too much humectant, ie there is an unused excess of humidifier.
- the invention has for its object to provide a method and an apparatus for moistening porous medical substances, with which easy handling and an effective use of the moistening agent are made possible.
- the method and the device according to the invention provide that the moistening of the porous medical substance is promoted by a vacuum suction effect.
- the penetration of the substance, that is to say the implant or transplant, with the moistening agent is promoted according to the invention by a suction effect which creates a pressure gradient which drives the moistening agent into the implant or transplant.
- the moistening of the implant or transplant can also be promoted by other effects such as the capillary effect. This capillary effect is regularly present anyway.
- the suction effect according to the invention has a considerable advantage over the time required for the moistening and also with regard to the homogeneity of the moistening, i. H. the completely uniform penetration of the material (the implant or the graft) with the humectant.
- the invention also enables precise metering of the amount of the dampening agent, so that the excess of dampening agent (ie the amount of the dampening agent that is not required for the dampening of the material) can be largely reduced.
- the implant or transplant is evacuated at a time interval before moistening.
- the suction effect is generated directly by the vacuum in the pores of the material.
- the suction effect can also be generated by evacuating a cavity which can be brought into a gas-conducting connection with the implant or transplant. If this gas-conducting connection is then established shortly before or during moistening and the moistening agent is supplied to the implant or transplant at another point (for example on the side opposite the gas-conducting connection), the moistening agent becomes due to the suction effect, so to speak, that it is drawn into and through the material of the implant or transplant, thus achieving uniform moistening inside the material. In this embodiment, the material is evacuated immediately before it is moistened.
- the device in the manner of an evacuable container with walls that essentially do not deform due to a vacuum.
- the porous medical material to be moistened can then be kept in stock in this container, the material of the implant or of the transplant also being evacuated.
- devices according to the invention are designed in the manner of an elastic vacuum packaging.
- a first chamber is provided, in which the implant or transplant is contained, and a second chamber, in which a moistening agent, ie a liquid, is contained.
- these chambers can then optionally be connected to one another in a liquid-conducting manner, when this connection is established for the purpose of moistening, a vacuum in the first chamber causes the moistening agent to be sucked into the material of the implant or transplant.
- the device has a septum for injecting a liquid with which the implant or transplant is to be at least partially moistened.
- the moistening agent contains a medicament.
- the device is a two-chamber system with a first chamber, in which the evacuated porous material is contained, and a second chamber for the moistening agent, wherein a septum can additionally be provided at a suitable point, through which a medicament can optionally be injected in addition to the moistening agent, so that when moistened together with the moistening agent it is homogeneous the material penetrates.
- the septum can be arranged so that the medication can be injected into the moistening agent or into the already flowing moistening agent.
- this liquid-conducting connection is first interrupted and this interruption, e.g. in the form of a membrane or the like, can be broken open by external pressure.
- this interruption e.g. in the form of a membrane or the like
- the user can force the membrane to break by pressure on the chamber in which the humidifying agent is contained, so that the humidifying agent is sucked in the direction of the implant to be moistened.
- a free space on the side located downstream of the implant or transplant e.g. in the form of a relatively rigid sleeve (compared to the elasticity of the film of the vacuum packaging), so that excess liquid which remains after saturation of the porous material is sucked away from the porous material, so that the material is loaded with exactly the required amount of liquid and no residues of liquid that could possibly interfere remain on it.
- an open hollow body e.g. to arrange a sleeve.
- This arrangement in an open hollow body is particularly preferred if the material does not have sufficient dimensional stability even when evacuated under the effect of the external air pressure (ie the atmospheric pressure).
- the arrangement in a hollow body can also be advantageous with material that is dimensionally stable with respect to the external air pressure.
- the moistening agent can thus enter the material at a precisely defined location and it can also be ensured that the moistening agent passes completely through the biological or organic material to be moistened. Excess moistening agent can also be removed in a simple manner by means of such a hollow body.
- a saline solution or a plasma are particularly suitable as humectants.
- Bones cancellous bone
- bone-like materials for example materials made from bone, are particularly suitable as medical porous material.
- the grafts can be xenografts or allografts.
- cancellous particles are known in the prior art, which are known as so-called.
- Such cancellous granules are used in a variety of surgical applications, e.g. in orthopedics, neurosurgery, ENT, or even in dental medicine.
- the dental fields of application include augmentation e.g. Implants in extraction alveoli, the augmentation of fenestration defects, furthermore the localized comb augmentation, in particular for the purpose of a later implantation, the reconstruction of the comb with prosthetic restoration, the reconstruction of defects, the filling of extraction alveoli, the filling of defects after e.g. root tip resection, filling after a cystectomy or filling after removal of retained teeth, etc.
- Such granules are also used after an osteotomy.
- Other areas of application are e.g. the filling of cranium defects or applications in the jaw area.
- Compressed tablets are also suitable as the porous body, for the moistening of which the invention is also well suited.
- such tablets can be pressed from the bone particles (so-called chips) described above in such a way that the resulting tablet is porous. In general, this process can be carried out with collagen-containing materials.
- the invention also relates to a method for producing the above-described porous medical implants or grafts, in which bone material is comminuted into particles and the particles are then compacted into porous bodies.
- "compacting” means that the bone particles are compressed and compressed to such an extent that they form a dimensionally stable composite which is porous throughout without any significant damage to the microbone structure.
- the manufacturing process for such compacted porous tablets made of bone particles involves painting the starting bone material, e.g. in a mortar, sieving to suitable particle sizes, and then compressing to a stable tablet. It has been shown (surprisingly) that a relatively dimensionally stable porous tablet can be obtained simply by pressing. If this tablet is then rehydrated, e.g. preferably with the vacuum suction effect described above, it swells up a little and can therefore be easily modeled so that the surgeon can fit and model the tablet or parts thereof (tablets of different sizes can also be made available) directly at the place of use.
- the porous body made of spongiosa particles compacted according to the invention as such already facilitates application in a large number of areas of application, for example those mentioned above, and on the other hand the porous body shaped in this way can be rehydrated much more easily and better than the granules, with rehydration is particularly preferred according to the evacuation technique described above.
- the term "rehydrating” is to be understood here in a broader sense - following the general medical usage - and generally includes moistening with a suitable liquid, not just with water or a saline solution. "Re- To hydrate "means here in particular” to moisten with (blood plasma).
- FIG. 1 shows a device for moistening a porous medical material in a disassembled state
- FIG. 2A, 2B, 2C and 2D a device according to FIG. 1 in various stages of assembly
- FIG. 3 shows a further exemplary embodiment of a device for moistening an absorbent medical material with a vacuum packaging.
- the device shown in the figures is particularly suitable for moistening a porous bone graft 10 previously produced and rehydrated in a known manner.
- a porous bone graft 10 can e.g. Have dimensions of typically a few centimeters.
- the porous bone graft 10 can e.g. without comminution (chip production) can only be obtained by sawing bones or according to the compacting of particles or chips explained above.
- the bone graft 10 used in this exemplary embodiment stands for a porous medical body of biological origin.
- the device has a lower part 12 made of e.g. clear plastic.
- the lower part 12 is made of a so-called blister material which, despite a certain elasticity, has sufficient strength to maintain dimensional stability in relation to the external air pressure on a few square centimeters, depending on the size of the graft 10, when a negative pressure is applied to the inside ,
- a depression 14 is formed in the lower part 12, into which the transplant fits precisely.
- An upper part 16 closes the trough 14 in an airtight manner against the external atmosphere in the manner of a cover.
- a septum 18 known as such (cf. also FIG. 2B) is also attached to the upper part 16 in an airtight manner and protrudes downward in FIG second trough 22 in the lower part 12.
- the septum 18 can be constructed in a manner known as such and has a membrane 20 at the top through which an injection needle (not shown) can be pierced.
- the terms “above” and “below” are used here in the sense of the usual position of use of the device.
- the said troughs 14 and 22 form a system of two chambers which are connected to one another by a channel 24.
- the channel 24 is designed in the form of a relatively flat and wide depression in the lower part 12.
- FIGS. 2A to 2D show individual stages of the assembly of a device according to FIG. 1.
- FIGS. 2A to 2D each show a bottom view of the lower part or the upper part and above it a cross section perpendicular to the main plane of the lower part at the level of the trough 22, with additional the trough 14 (the actual ones would not be included in the cut) is shown.
- FIG. 2A shows the lower part 12 (blister) made of a transparent film with a thickness of 0.2 to 0.4 mm.
- the sizes of the troughs 14 and 22 are based on requirements, i.e. the dimensions of the graft 10 or the intended septum 18 can be adjusted.
- FIG. 2B shows the upper part 16 with the septum 18 attached to it in an airtight manner.
- the upper part 16 can e.g. consist of a cover film which is more elastic than the lower part and has thicknesses in the range of 0.1 to 0.2 mm.
- FIG. 2C shows the lower part 12 and the upper part 16 in a partially assembled state.
- a welding strip 26 partially connects the lower part and the upper part, an area 25 initially remaining unsealed, so that air can be sucked out of the troughs 14, 22 through the open area 25 with a vacuum pump (not shown).
- the lower part and the upper part lie against one another over a large area and a graft 10 arranged in the depression 14 is also evacuated.
- the trough 22 assigned to the septum 18 and also the septum are evacuated.
- the lower part 12 and upper part 16 are sufficiently stable to enable the evacuation (a modified exemplary embodiment with a more elastic material in the manner of a vacuum packaging is explained further below).
- a further welding strip 28 is e.g. thermally activated or applied, which closes the entire space between the lower part 12 and the upper part 16 with the exception of two tear-open edges 30a, 30b, together with the adhesive strip 26 already mentioned.
- a label 32 is placed on top 26 to provide the user with the required information about graft 10.
- the user injects a suitable liquid, e.g. a saline solution or a plasma, if necessary with added medication.
- a suitable liquid e.g. a saline solution or a plasma
- the size of the trough 22 is adapted to the size of the septum in such a way that the liquid reaches the trough 14 and thus the transplant 10 directly via the channel 24. Since the trough 22 is adapted in size to the external dimensions of the septum 18 and also the size of the trough 14 to the size of the transplant 10, the user can adapt the amount of liquid supplied to the actual need, that is to say only add as much liquid, as is required to moisten the graft 10. For example, the amount of liquid to be supplied can be displayed to the user on the label 32.
- FIGS. 1 and 2 can be modified, for example, in such a way that vacuum packaging with full elasticity is provided as the material for the wrapping of the parts mentioned.
- a vacuum packaging is shown schematically in Figure 3.
- the vacuum packaging 40 has a flat carrier 42 on which two foils 44, 46 are laminated one above the other. Between the foils 44, 46, a liquid container 48 is formed like a cushion, which is filled to the brim with a liquid with which a medical, liquid-absorbing material 50 is to be moistened.
- the material 50 is located in a sleeve 45 which is sufficiently firm to largely protect the material 50 against external influences such as extreme pressure or the like.
- the material of the sleeve 54 is nevertheless somewhat elastic given the dimensional stability mentioned above.
- a ring 56 at the entrance to the sleeve 54 secures the sleeve against squeezing, and likewise a relatively rigid receptacle 52 for excess liquid is provided at the other end of the sleeve 54, into which a nozzle 58 projects, through which the excess liquid enters the container 52 occurs.
- the interior between the foils 44, 46 including the sleeve 45 and the container 52 is evacuated.
- the user presses the liquid container 48 so strongly (for example with the fingers) that a predetermined breaking point for the sleeve 54 breaks open, which is located approximately at the location of the arrow in FIG. 3 between the foils 44, 46, so that liquid from the container 48 enters the interior of the sleeve 54 through the ring 56 and rehydration is carried out there in the sense described above.
- a certain suction effect is created in the interior of the sleeve via the nozzle 58 and excess liquid is removed from the material to be moistened. In this way, precise control of the humidification can be carried out if the volume of the container 52 and thus, among other things. the above-mentioned suction effect is also adapted to the material 50 to be moistened.
- This exemplary embodiment according to FIG. 3 can also be modified such that a septum for injecting the liquid is arranged between the elastic foils 44, 46 of the vacuum packaging 40, insofar as similar to the exemplary embodiment according to FIGS. 1 and 2.
- the invention can also be implemented with a relatively rigid container into which the porous implant or transplant is arranged to be evacuated.
- a protective gas is used to temporarily load the porous material with it.
- an inert gas can be used, but preferably a gas that is soluble in the liquid used for humidification.
- CO 2 is a preferred gas in order to fill more or less the voids in the porous material.
- CO 2 is very soluble in a variety of liquids that are used for medical applications, especially water.
- the use of a protective gas to feed the porous material has the advantage that the protection is improved during the storage of the material prepared in this way. During storage, the protective gas is kept in the chamber, which also contains the porous material, whereby the pressure can be selected as follows:
- the pressure of the protective gas is lower than the pressure of the external atmosphere, a suction effect with regard to the liquid occurs when the material is moistened. If the pressure of the protective gas is selected so that it is greater than the pressure of the external atmosphere, the protective effect is improved.
- the pressure of the protective gas corresponds to the pressure of the external atmosphere, the charging of the gas into the porous material is facilitated.
- the selection of the print ultimately depends on the circumstances and the desired effect.
- the shielding gas can be filled into the porous material in the factory where the device containing the material is manufactured, which material is later to be humidified in a hospital or the like.
- a protective gas can also be combined with the system described above, in which a cavity is provided downstream of the material, in such a way that a vacuum can be applied to this cavity, which, at least at times, is in liquid-conducting connection with the one containing the porous material Chamber stands so that excess liquid and, at least partially, the protective gas are sucked away from the material, both the excess liquid and at least part of the protective gas being transferred away from the porous material into the cavity, so that the porous material is completely homogeneously moistened , without excess liquid that could cause difficulties in medical applications of the material.
