Definitions
- the present invention relates to a syringe for viscoelastic solutions used in the medical and surgical fields.
- Such solutions are currently used in rheumatology in the form of intra-articular injections, in dermatology for filling wrinkles, in plastic surgery, in abdominal surgery, and in ophthalmic surgery, without this list of applications necessarily being limited in the time.
- the present invention can be applied during cataract surgery, with the placement of an intraocular lens.
- the role of viscoelastic solutions is to create the spaces necessary for surgical procedures, and to protect the ocular tissues, in particular the corneal endothelium.
- An important condition is that this type of solution must be withdrawn by suction at the end of the intervention, otherwise there is a risk of causing a harmful increase in intraocular pressure.
- a product generally having a higher dynamic viscosity at high shear rate is generally used first. This is particularly the case during the surgical stages called capsulorhexis and phacoemulsification, which are surgical techniques well known to those skilled in the art.
- a product having a lower dynamic viscosity for similar shear conditions is preferably used second, when the intraocular lens is placed.
- the present invention aims to provide a syringe for viscoelastic solutions in the medical field which does not reproduce the aforementioned drawbacks.
- the present invention aims to provide a syringe for viscoelastic solutions which simplifies the task of the surgeon, and which allows the use of products having optimal characteristics at each stage of the intervention.
- the present invention also aims to provide such a syringe for viscoelastic solutions which is simple and inexpensive to manufacture and assemble.
- the present invention therefore relates to a device for dispensing viscoelastic solutions consisting of a syringe which contains at least two viscoelastic solutions having different properties, said solutions being successively dispensed, in a predetermined order, characterized in that said syringe comprises at least a movable diaphragm, separating said at least two viscoelastic solutions.
- said diaphragm includes seals.
- said movable diaphragm incorporates an opening, preferably of small size, allowing the expulsion of the viscoelastic solution disposed upstream of the diaphragm after total distribution of the viscoelastic solution disposed downstream of the diaphragm.
- said opening is closed by a membrane, said syringe comprising opening means, such as a piercing tip, adapted to open said membrane when the viscoelastic solution disposed downstream of the diaphragm has been completely distributed.
- a micro air bubble is placed in said opening of the diaphragm, to avoid any contact between the viscoelastic solutions.
- said diaphragm is connected by a temporary mechanical connection to the piston of the syringe during the distribution of the viscoelastic solution disposed downstream of the diaphragm, said mechanical connection temporary being removed after total distribution of said viscoelastic solution, to allow distribution of the viscoelastic solution disposed upstream of the diaphragm.
- said at least two viscoelastic solutions have different rheological properties.
- said at least two viscoelastic solutions have chemical compositions and / or molecular weights of their active principle and / or different concentrations of their active principle.
- said at least two viscoelastic solutions have different dynamic viscosities, at high shear rate.
- the present invention also relates to the use of a syringe as described above in cataract surgery.
- - Figure 1 is a schematic cross-sectional view of a syringe according to a first embodiment of the present invention
- - Figure 2 is a schematic cross-sectional view of a syringe according to a second embodiment of the present invention.
- a syringe 1 comprises a generally cylindrical syringe body 2 comprising on the one hand a dispensing orifice 3 and on the other hand a piston 4 actuated by an actuating rod 5.
- the user presses on the rod d actuation 5 to move the piston 4 inside the body 2 to dispense the product contained in the syringe through the dispensing orifice 3.
- the syringe 1 comprises at least two viscoelastic solutions VI, V2 which have different properties, said solutions VI, V2 being distributed successively, in a predetermined order. More particularly, the at least two viscoelastic solutions VI, V2 are distinguished by their chemical nature, and / or the molecular weight of their active principle and / or the concentration of this active principle. More generally, the viscoelastic solutions of the present invention have different rheological properties, and advantageously they have different dynamic viscosities, for high shear rates.
- a movable diaphragm 10 between the solutions VI, V2.
- This diaphragm 10 preferably comprises seals 15 on its external periphery which cooperate with the body, the body 2 of the syringe 1.
- this diaphragm 10 can slide against the internal wall of the body of the syringe in a sealed manner, while being guided like the plunger of the syringe.
- the diaphragm 10 moves at the same time as the piston 4, under the effect of the thrust which is transmitted by the second viscoelastic solution V2.
- the diaphragm 10 has an opening 11, preferably arranged centrally, preferably of small size. This is generally sufficient for the solutions VI and V2 to mix before the solution VI is fully dispensed, as shown in the example in FIG. 1, even if this opening 11 is not closed.
- the force to be exerted to cause the passage of the second viscoelastic solution V2 through the small opening 11 must generally be greater than the friction of the diaphragm 10 against the wall of the syringe, taking into account the possible presence of the mechanical connection.
- the diaphragm 10 is shown in a completely sealed manner, with a membrane 12 which closes the opening 11, which in this case can be of larger dimension than in the embodiment shown in Figure 2.
- This implementation can be considered in the case where solutions VI and V2 tend to mix, for example by simple osmotic rebalancing or during the distribution of the first solution VI.
- the syringe 1 then comprises opening means, such as a piercing tip 8, which are adapted to open said membrane 12 when the diaphragm 10 comes into contact with the bottom of the syringe, that is to say when the first viscoelastic solution VI which is disposed downstream of the diaphragm has been completely distributed.
- the syringe may have at its dispensing opening 3 a safety system
- Luer-Lock which allows to lock a cannula or an injection needle on the tip of the syringe.
- a particularly advantageous use of the present invention relates to cataract surgery, but the present invention is not limited to this use.
