DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a device and a method for simulating an examination and/or a surgical operation, performed by an operator on a simulated organ.
The term organ is intended to mean any clearly differentiated part of a living body which fulfils a specific function, such as an eye, an ear, a nose, etc.
The invention has a particularly important, but not exclusive, application in the field of ophthalmology, in the context of teaching the examination of the eye and the treatment of the fundus of eye by photocoagulation, using a laser radiation.
It is known that, like the surgical technique of photocoagulation by impact of a laser radiation, the examination of the eye uses a device comprising an apparatus referred to as a biomicroscope, including a binocular, magnifying optics, a source (slit lamp) for illuminating the eye and, if appropriate, a laser radiation source in the case of an apparatus equipped for treating the eye by photocoagulation.
The apparatus is activated by a control stage system arranged on an examining table.
The device also comprises an examination lens designed to be manipulated by the operator performing the examination. The examination lens is placed directly on the cornea and its optical design makes it possible to observe the various regions of the eye.
Currently, training or teaching in the field of eye examination and laser-radiation treatment can only take place during interventions performed on patients.
This practice has the drawback of limiting the training just to those pathologies which are encountered.
Furthermore, it entails risks of injury due to mistakes in manipulating the laser.
Another teaching method consists in using porcelain phantom eyes. However, such a method is limited just to observation and does not allow prior evaluation of the effects of a laser radiation in some particular circumstances.
The object of the invention is to remedy these drawbacks by proposing a device and a method which suit practical requirements better than those previously known, in particular because they no longer require intervention on the organ proper and because it allows genuine dissociation of the therapy process from the learning process.
To this end, the invention essentially proposes a device for simulating an intervention on an organ by an operator, characterized in that it includes control stage system actuable manually by the operator, the said system being designed to displace the binocular in an orthonormal triaxial frame Ox, oy, Oz, adjusting the dimensioning of the said slit lamp which is capable of illuminate the organ, organ to be examined and of projecting the said image onto the said miniaturized video screen or screens, with means for manual actuation by an operator, which are designed to simulate the relative displacement of the said simulated examination lens relative to the said video image, the said simulation means and the said computation means being designed so that the changing of any one of the parameters relating to the displacement of the binocular, to the adjustment of the slit lamp, to the magnification or to the examination lens modifies the video image of the simulated organ in real-time or substantially in real-time.
The general concept of the invention actually relies on the simulation of the image of the patient's organ by a synthetic computer image.
The usual observation conditions are furthermore sure to be respected by virtue of the preservation of the binocular and its control stage system, which remain identical to those in the prior art.
The emission of a laser radiation and its control panel, the slit lamp and its adjustment means, the magnification of the biomicroscope and the examination lens are, on the other hand, entirely simulated.
For its part, the patient's organ is replaced by one or two video screens, integrated with the biomicroscope.
A single screen will make it possible to supply the two objectives of the binocular with the same image, whereas two screens make it possible to supply one image per objective.
