CAMPO DE LA INVENCIÓN FIELD OF THE INVENTION
Esta invención tiene su aplicación dentro de la industria auxiliar de la medicina cirugía y veterinaria. This invention has its application within the auxiliary industry of surgery and veterinary medicine.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Los bisturíes quirúrgicos generalmente empleados, consisten en un mango sstsrilteabie y rsuii toóle, en suyo extremo existe una lengüeta para alojamiento de ie cuchilla. The surgical scalpels generally used, consist of a handle sstsrilteabie and rsuii toóle, in its end there is a tongue for accommodation of ie blade.
Las cuchillas,, tanto por cuestión de higiene quirúrgica, corno por su propia efectividad, son de un solo uso, o incluso, en función de la naturaleza de la intervención quirúrgica, pueden usarse diferentes cuchillas en une misma operación, de características también diferentes, según los tejidos o pedes del cuerpo en los que se practique la intervención o iguales, si han sufrido desgaste que las hace peco adecuadas para seguir siendo utilizadas. The blades, both for the sake of surgical hygiene, as for their own effectiveness, are for single use, or even, depending on the nature of the surgical intervention, different blades can be used in the same operation, with different characteristics, according to the tissues or pedes of the body in which the intervention is performed or the same, if they have suffered wear that makes them suitable sin to continue being used.
Por el centrarlo, al mango se reutiliza, previa esterilización; o en los casos antes señalados de uso de diferentes cuchillas, en una misma intervención, generalmente se intercambia la cuchilla, pero al cirujano sigue usando el mismo mango. By centering it, the handle is reused, after sterilization; or in the aforementioned cases of use of different blades, in the same intervention, the blade is usually exchanged, but the surgeon continues to use the same handle.
La operación de retirada y sustitución de la cuchilla, exige generalmente el uso de las dos manas, y requiere la realización de ciertas operaciones sobre la cuchilla, Esta operación manual presenta ciertas dificultadas, en particular si el mango y la propia cuchilla están mojados como suele ser habitual, pero sobre todo presenta graves riesgos, derivados del peligro de sufrir un corte accidental con las consiguientes consecuencias, directas corno son las derivadas de la lesión que se produce, o indirectas como las derivadas del riesgo de contagio de enfermedades.
En razón esencialmente de la proliferacion de enfermedades de transmisión sanguínea, como el Sida, Hepatitis, etc, se han desarrollado diversos dispositivos, que pretenden proporcionar una simplification en la retirada y sustitución de la cuchilla del bisturí, y que proponen tanto solucionas que afectan a la conformacion del propio bisturí, como a dispositivos externos que simplifican su retirada y sustitución. Entre dichas Patentes pedemos citar la Patente Australiana 64111/90, o Patentes Europeas 589233, 1009301 ó 779797, asi como las Patentes US 4998334 y 5361902. The operation of removing and replacing the blade generally requires the use of the two handles, and requires the performance of certain operations on the blade. This manual operation presents certain difficulties, particularly if the handle and the blade itself are wet as usual. be habitual, but above all it presents serious risks, derived from the danger of suffering an accidental cut with the consequent consequences, direct as they are derived from the injury that occurs, or indirect as those derived from the risk of contagion of diseases. Due essentially to the proliferation of blood-borne diseases, such as AIDS, Hepatitis, etc., various devices have been developed, which aim to provide a simplification in the removal and replacement of the scalpel blade, and which propose both solutions that affect the conformation of the scalpel itself, as to external devices that simplify its removal and replacement. Among these patents we can mention Australian Patent 64111/90, or European Patents 589233, 1009301 or 779797, as well as US Patents 4998334 and 5361902.
Sin embargó, la mayor parte de los antecedentes conocidos presentan ciertas desvéntajas o inconvenientes en su aplicación. Por un lado, muchos de ellos requieren la utilización de un dispositivo eterno, lo que se traduce en la necesidad de su esterilización, puesto que de otro modo no seria factible su uso en al caso de mirada y sustitución durante una intervención quirúrgica: otros requieren et uso de ambas manos, o la realización da operaciones complicadas qué distraen la atencion del punto esencial que es la intervención quírurgica. However, most of the known antecedents present certain disadvantages or inconveniences in their application. On the one hand, many of them require the use of an eternal device, which translates into the need for sterilization, since otherwise its use would not be feasible in the case of look and replacement during a surgical intervention: others require The use of both hands, or the realization, gives complicated operations that distract attention from the essential point that is the surgical intervention.
Para evitar ia problemática antes descrita, tamo m relación con la seguridad en ta retirada y sustitución da cuchillas en bisturíes, como la derivada del uso de dispositivas extamos, como al riesgo de caída accidental de la cuchilla, la presente invención propone un bisturí con empujador de seguridad, que permite la expulsión de la cuchilla sin manipularla o impide el accionamiento accidental o involuntario del eistema de retirada de las cuchillas, y mejora su funcionamiento,de modo tal que sin accionar previamente este sistema de segundad, de funcionamiento simple pero efectivo, es imposible retirar la cuchilla, lo que imposibilita tambien la caida accidental de la misma. In order to avoid the problem described above, it also relates to the safety in the removal and replacement of blades in scalpels, such as that derived from the use of extendable devices, such as the risk of accidental fall of the blade, the present invention proposes a scalpel with a pusher safety, which allows the expulsion of the blade without manipulating it or prevents accidental or involuntary activation of the blade removal system, and improves its operation, so that without previously operating this safety system, simple but effective operation, it is impossible to remove the blade, which also makes it impossible to accidentally drop it.
