The present invention refers to an apparatus for the detection of at least one parameter, in particular kinetic, in relation to the heart, or myocardium, of a human being or an animal.
In particular, the apparatus can be used during surgical operations, in particular performed on the heart, or myocardium itself, inside a corresponding operating theatre.
An apparatus for the detection of at least one parameter, in particular kinetic, in relation to the heart, or myocardium, of a human being or an animal, especially for use during surgical operations, in particular performed on the heart, or myocardium itself, inside a corresponding operating theatre, is known.
Said already known apparatus comprises a detection means for the detection of spatial or mechanical, movements of said heart, or myocardium, and a control means, or processor of the apparatus, in particular adapted to, or configured to, process the signals, or data, provided by said detection means for providing at least one corresponding parameter, in particular kinetic, in relation to said heart, or myocardium, of said human being or animal.
This already known apparatus uses a 2D television camera for the detection of the patient's heart, but this has many limitations and does not allow a good kinetics of the patient's heart to be obtained, which cannot therefore be conveniently assessed by the clinician.
In addition, due to the fact that there are very bright lights in the operating theatre that the surgeon needs in order to have a good view at all times during the operation, however, light refractions occur that can lead to problems in processing the 2D images detected, with the risk of obtaining totally misleading data.
Moreover, said already known apparatus is manually positioned, with difficulty and discomfort on the part of the operator, at the patient's heart, in the pre-operating step, then removed and repositioned, again at the same heart of the patient, in the post-operating step, which leads, for obvious reasons, to positions that will never be perfectly coincident with each other and which consequently lead to clinical comparisons that are invalidated by such a technical distortion.
In particular, according to the prior art, it is not possible to obtain a particularly accurate detection of the kinetics of the heart, and in particular it is not possible to assess the ejection fraction, the fractional shortening and the ventricular hemodynamic load of said heart, or myocardium, without resorting to particularly invasive techniques for the patient.
With the present invention it is therefore wished to propose a new solution and an alternative to the solutions known up to now and in particular it is proposed to overcome one or more of the drawbacks or problems referred to above, and/or to satisfy one or more requirements referred to above and/or in any case experienced in the art, and in particular which can be deduced from the above.
An apparatus is therefore provided for the detection of at least one parameter, in particular kinetic, in relation to the heart, or the myocardium, of a human being or an animal, especially the apparatus being usable during surgical operations, in particular performed on the heart, or myocardium, itself, inside a corresponding operating theatre; comprising a detection means for the detection of spatial or mechanical, movements of said heart, or myocardium, and a control means, or processor, of the apparatus, in particular adapted to, or configured to, process the signals, or data, provided by said detection means for providing at least one corresponding parameter, in particular kinetic, in relation to said heart, or myocardium, of a human being or animal; characterized in that said detection means for the detection of the spatial, or mechanical, movements of said heart, or myocardium, is adapted to detect the distance, or depth, i.e. the variation in distance, or depth, of one or more points of said heart, or myocardium, in particular of one or more points of a corresponding surface or wall of said same heart, or myocardium, by the detection means for detecting the spatial, or mechanical, movements of said heart, or myocardium.
In this way, a particularly accurate detection of the kinetics of the heart is obtained, in particular it is possible to assess the ejection fraction, the fractional shortening and the ventricular hemodynamic load of said heart, or myocardium, all with an apparatus that is in itself non-invasive for the patient.
This and other innovative aspects or respective advantageous embodiments, are however, set forth in the appended claims, the technical characteristics of which can be found, together with corresponding advantages achieved, in the following detailed description, illustrating a purely non-limiting example of the embodiment of the invention, which is made with reference to the appended drawings, in which:
