Abstract

The system is designed to locate or detect if in a surgical operation compresses or surgical instruments have been forgotten inside the patient. The system comprises the incorporation of a receiver in the compresses, said receiver being formed of a coil and a capacitor for generating an electric current induced when the receiver is subjected to the electromagnetic field created by an external emitter provided with means for setting in operation the receiver and with a coil connected to a capacitor, so that the self-induced current created in the receiver when stopping the electromagnetic field is detected by the emitter itself, thus generating in the emitter a current capable of activating a supply circuit for a light and/or acoustic signalling device which forms part of the emitter itself, to indicate, in the case of activation, the existence of the surgical compress inside the patient who has been operated.

Description

SISTEMA DE DETECCIÓN DE COMPRESAS DENTRO DEL CAMPO QUIRÚRGICO MEDIANTE ELEMENTOS ACTIVOS O PASIVOS COLOCADOS SYSTEM OF DETECTION OF COMPRESSES WITHIN THE SURGICAL FIELD THROUGH ACTIVE OR LIABILITIES PLACED
EN LAS COMPRESASIN THE COMPANIES
La invención se refiere a un sistema de detección de compresas dentro del campo quirúrgico mediante elementos activos o pasivos colocados en las compresas, cuya evidente finalidad es conseguir de manera fácil, segura y eficaz, la localización de los textiles (compresas y gasas) e instrumental quirúrgico que se utilizan necesariamente en las intervenciones quirúrgicas. El sistema se basa en incorporar sobre los propios textiles quirúrgicos, un receptor que en combinación funcional con un emisor externo posibilita la detección pretendida; o bien incorporar un código magnético en los textiles y en el instrumental detectable mediante un receptor en movimiento cercano.The invention relates to a system for detecting compresses within the surgical field by means of active or passive elements placed in the compresses, whose obvious purpose is to easily, safely and effectively achieve the location of textiles (compresses and gauze) and instruments Surgical that are necessarily used in surgical interventions. The system is based on incorporating on the surgical textiles themselves, a receiver that in functional combination with an external emitter enables the intended detection; or incorporate a magnetic code in textiles and instruments detectable by a receiver in close motion.
Actualmente, no existen medios que permitan una eficaz localización de compresas y material quirúrgico utilizadas en las intervenciones quirúrgicas, sin que suponga riesgos para el paciente. Únicamente se puede realizar la localización cuando la intervención ha finalizado, pero no durante el desarrollo de la misma.Currently, there are no means that allow an effective location of compresses and surgical material used in surgical interventions, without involving risks for the patient. The location can only be done when the intervention has finished, but not during its development.
Uno de los sistemas que actualmente se utiliza para conocer si ha quedado o no un instrumento o compresa en el interior del paciente, se basa en la utilización de hilos que contienen sulfato de bario, substancia radiopaca detectable mediante rayos X, y cuya utilización rutinaria no está justificada por el riesgo aumentado de cáncer que produciría en la comunidad, o por procedimientos tan primitivos y expuestos al error humano, consistentes en contar las compresas que se utilizan y colgar pinzas de un cordel representando a cada compresa.One of the systems currently used to determine whether or not an instrument or compress has been left inside the patient is based on the use of threads containing barium sulfate, a radiopaque substance detectable by X-rays, and whose routine use is not is justified by the increased risk of cancer that would occur in the community, or by procedures so primitive and exposed to human error, consisting of counting the compresses used and hanging clamps from a string representing each compress.
Hay incluso situaciones agravantes que pueden alterar el contaje, tal como empaquetamiento indebido de un número erróneo de compresas en un paquete, intervenciones complicadas que obligan a descuidar el contaje para atender la urgencia vital, que alguna compresa o instrumental quirúrgico pueda acompañar a una pieza extirpada ( o a un recién nacido), que se produzca un relevo, por turno de trabajo, de personal durante la intervención, etc.. Por lo expuesto no existe ningún método seguro β inocuo que permita la seguridad de dejar un campo operatorio libre de material quirúrgico.There are even aggravating situations that can alter the count, such as improper packaging of an erroneous number of packs in a package, complicated interventions that make it necessary to neglect the count to attend to the vital urgency, that some compress or surgical instrument can accompany an excised piece (or to a newborn), that there is a relief, by work shift, of personnel during the intervention, etc. For the abovementioned, there is no safe β-safe method that allows the safety of leaving an operative field free of surgical material .
Como excepción, ante una duda razonable, puede realizarse una radiografía intraoperatoria, pero ésta exige movilizar a un paciente inconsciente e intubado, con el consiguiente riesgo de una lesión traqueal, de un vaso sanguíneo canalizado o de una articulación del enfermo. Si la localización se produce "a posteriori", será porque el instrumental ha producido una complicación, lo que obligará a una nueva rβintervención de mayor riesgo que la primera.As an exception, when faced with a reasonable doubt, an intraoperative radiograph may be performed, but this requires mobilizing an unconscious and intubated patient, with the consequent risk of a tracheal lesion, a channeled blood vessel or a joint of the patient. If the location occurs "a posteriori", it will be because the Instrumentation has produced a complication, which will force a new intervention with a higher risk than the first.
La incidencia estimada de abandono involuntario de compresas, con mucho el material quirúrgico predominante, es de 1 entre 100 a 3.000 intervenciones. Estas compresas pueden producir una reacción supurativa, comportándose de manera similar a un absceso, lo que obliga a una intervención quirúrgica para extraer el material extraño, o por otra parte, producir una reacción de fibrosis y encapsulamiento que en el mejor de los casos no producirá ninguna molestia durante la vida del paciente, o por el contrario asemejarse tanto a un proceso neoplásico que haga someterse innecesariamente al paciente a una cirugía radical oncológica. Con todo la mortalidad podría ascender, atendiendo a algunas fuentes, a un 20% del total de compresas abandonadas.The estimated incidence of involuntary abandonment of compresses, by far the predominant surgical material, is 1 in 100 to 3,000 interventions. These compresses can produce a suppurative reaction, behaving similarly to an abscess, which forces a surgical intervention to extract the foreign material, or on the other hand, produce a fibrosis and encapsulation reaction that will not produce at best no discomfort during the life of the patient, or on the contrary resemble so much a neoplastic process that makes the patient unnecessarily undergo radical oncological surgery. With all the mortality it could amount, taking care of some sources, to 20% of the total abandoned packs.
Tampoco hay que olvidar otro factor, cada día mas importante y que hace cada vez más necesario encontrar un método seguro para detectarlas. Se trata del enorme cúmulo de reclamaciones judiciales que está soportando la clase médica, ante el posible daño que puedan sufrir los pacientes. Se calcula que más de un 10% de las demandas ganadas contra médicos son por este concepto.Nor should we forget another factor, each day more important and that makes it increasingly necessary to find a safe method to detect them. This is the huge accumulation of legal claims that the medical class is supporting, given the possible harm that patients may suffer. It is estimated that more than 10% of the claims won against doctors are for this concept.
El sistema que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, basándose en un método electromagnético que puede tener varías vías de realización.The system that has been recommended has been conceived to solve the problem described above, based on an electromagnetic method that can have several ways of realization.
Así, el sistema de la invención, se basará fundamental y preferentemente en la incorporación a textiles quirúrgicos (gasas y compresas) de un receptor que incorpora un circuito constituido por una bobina y un condensador eléctricos conectados entre sí, permitiendo que se genere una corriente eléctrica inducida cuando es sometido a un campo electromagnético, de manera que al cesar éste se generará una corriente inducida en el aludido receptor, que a su vez podrá ser detectada por un emisor concebido y constituido convenientemente.Thus, the system of the invention will be fundamentally and preferably based on the incorporation into surgical textiles (gauze and compresses) of a receiver that incorporates a circuit consisting of an electric coil and capacitor connected to each other, allowing an electric current to be generated. induced when it is subjected to an electromagnetic field, so that when it ceases it will generate an induced current in the aforementioned receiver, which in turn can be detected by an emitter conceived and conveniently constituted.
El receptor estará montado en el interior de una envolvente o carcasa de plástico con las características de flexibilidad e inocuidad adecuadas para evitar la rotura y la toxicidad en el ser humano. Estructuralmente, dicho receptor estará determinado por la superposición de tres capas, siendo las externas conductoras de la electricidad y la intermedia aislante para completar la formación del condensador eléctrico.The receiver will be mounted inside a plastic enclosure or housing with the appropriate flexibility and safety features to prevent breakage and toxicity in humans. Structurally, said receiver will be determined by the superposition of three layers, the external conductors of electricity and the insulating intermediate to complete the formation of the electric capacitor.
En cuando al emisor, en el mercado existen numerosos generadores susceptibles de realizar la función correspondiente. Por otro lado, el sistema puede estar basado en la incorporación de un código magnético en las compresas y en los instrumentos quirúrgicos, de manera que un campo magnético en movimiento generará una corriente eléctrica inducida en un circuito compuesto por una bobina eléctrica, en cuyo caso el movimiento no provendrá del material quirúrgico portador del código magnético, sino del receptor en movimiento cercano.As for the issuer, in the market there are numerous generators capable of performing the corresponding function. On the other hand, the system may be based on the incorporation of a code magnetic in the compresses and in the surgical instruments, so that a moving magnetic field will generate an electric current induced in a circuit composed of an electric coil, in which case the movement will not come from the surgical material carrying the magnetic code, but from the receiver in close motion
Las ventajas que se pueden obtener mediante el sistema propuesto, son innumerables, pudiβndo destacar como más importantes las siguientes:The advantages that can be obtained through the proposed system are innumerable, being able to highlight as more important the following:
- Eliminación de la presencia indeseada de compresas lo que supone para los pacientes evitar riesgos sobre añadidos a los de la propia intervención quirúrgica, consistentes en infecciones más o menos graves, fracturas tardías, someterse a cirugías radicales oncológicas por falsos diagnósticos, e incluso , la muerte. En el mejor de los casos será precisa una reintervención.- Elimination of the unwanted presence of compresses, which means that patients avoid risks over additions to those of the surgery itself, consisting of more or less serious infections, late fractures, undergo radical oncological surgeries for false diagnoses, and even the death. In the best case, a reintervention will be necessary.
- Eliminación de un factor de riesgo para los módicos, hoy en día no evitable, en las intervenciones quirúrgicas y, evitar, por una parte que se ponga en entredicho su honorabilidad profesional y, por otra, eliminar reclamaciones judiciales, tanto civiles como penales.- Elimination of a risk factor for the modicos, nowadays not avoidable, in the surgical interventions and, to avoid, on the one hand that their professional honorability is called into question and, on the other, to eliminate judicial claims, both civil and criminal.
- Es evidente que existen terceros ajenos al acto quirúrgico, que podrían verse favorecidos, si no hay reclamaciones judiciales contra los médicos, al eliminarse la existencia indeseada de compresas. Entre ellos podríamos citar las Compañías de Seguros, que han de soportar en la actualidad el pago de elevadas indemnizaciones, pero que por ello cobran también primas muy elevadas a los asegurados.- It is clear that there are third parties outside the surgical act, which could be favored, if there are no legal claims against doctors, by eliminating the unwanted existence of compresses. Among them we could mention the Insurance Companies, which currently have to bear the payment of high indemnities, but for that reason they also charge very high premiums to the insured.
Podemos citar asimismo, a los diversos sistemas de Salud a los que muchos pertenecemos y en los que se practican un elevadísimo número de intervenciones quirúrgicas. Para complementar la descripción que seguidamente se va a realizar y con objeto de ayudar a una mejor comprensión de las características de la invención, se va a realizar una descripción detallada en base a un juego de dibujos que se acompañan a esta memoria descriptiva, formando parte integrante de la misma, y en donde con carácter meramente orientativo y no limitativo, se ha representado lo siguiente: En la figura 1a, se muestra una representación esquemática de una materialización de un emisor que forma parte del sistema objeto de la invención.We can also mention the various health systems to which many belong and in which a very high number of surgical interventions are performed. To complement the description that will then be made and in order to help a better understanding of the characteristics of the invention, a detailed description will be made based on a set of drawings that accompany this descriptive report, forming part integral of the same, and where with merely indicative and non-limiting nature, the following has been represented: In figure 1 a , a schematic representation of a materialization of an emitter that is part of the system object of the invention is shown.
En la figura 2a, se muestra una representación también esquemática de una compresa dotada del receptor que también forma parte del sistema de la invención.In figure 2 a , a schematic representation of a compress provided with the receiver which is also part of the system of the invention is also shown.
Según y como puede verse en las figuras referidas, una forma de realización práctica del sistema es aquella que se basa en la utilización de un emisor (1 ) y de un receptor (2), siendo éste segundo componente o elemento el que se incorporará a la compresa (3) cuya detección se pretende.According to and as can be seen in the aforementioned figures, a practical embodiment of the system is one that is based on the use of an emitter (1) and a receiver (2), this second component or element being the one to be incorporated into the compress (3) whose detection is intended.
Dicho receptor (2) incluye un circuito (4) formado básicamente por una bobina y un condensador eléctricos, estando éstos dispuestos en el interior de una carcasa de plástico (5) con asas (5').Said receiver (2) includes a circuit (4) basically formed by an electric coil and capacitor, these being arranged inside a plastic housing (5) with handles (5 ').
Por su parte, el emisor (1 ) incluirá un generador (6) de corriente eléctrica capaz de crear un campo magnético; un circuito (7) formado por una bobina y un condensador eléctricos; un circuito eléctrico (8) asociado a un elemento señalizador, tal como una lámpara incandescente, led o incluso a un señalizador acústico; un interruptor (9) de puesta en marcha del generador (6), y la correspondiente carcasa (10) en la que van incluidos dichos componentes del emisor (1).For its part, the emitter (1) will include an electric current generator (6) capable of creating a magnetic field; a circuit (7) formed by an electric coil and capacitor; an electrical circuit (8) associated with a signaling element, such as an incandescent lamp, led or even an acoustic signaling device; a generator start-up switch (9) (6), and the corresponding housing (10) in which said transmitter components (1) are included.
El funcionamiento es como sigue:The operation is as follows:
Mediante la activación del emisor (1) a través de su correspondiente interruptor (9), se creará una corriente eléctrica en el generador (6), dando origen a un campo magnético, el cual si encuentra en su camino la bobina del receptor (2) incorporado a la compresa (3) creará en dicha bobina una corriente eléctrica que, por efecto o fenómeno Faraday, creará un campo magnético que vuelve hacia la bobina (7) del emisor (1 ), de manera que ésta, al captar ese campo magnético procedente del receptor (2), creará una pequeña corriente eléctrica que activa el señalizador asociado al circuito (7), lo que indicará que efectivamente en el paciente intervenido ha quedado una compresa.By activating the emitter (1) through its corresponding switch (9), an electric current will be created in the generator (6), giving rise to a magnetic field, which if it finds in its path the receiver coil (2 ) incorporated into the compress (3) will create in said coil an electric current that, by Faraday effect or phenomenon, will create a magnetic field that returns to the coil (7) of the emitter (1), so that it, when capturing that field magnetic from the receiver (2), will create a small electric current that activates the signaling device associated with the circuit (7), which will indicate that a compress has been left in the operated patient.
En caso de no activación del señalizador acústico o luminoso del emisor (1 ), quiere decir que no existe compresa en el paciente. In case of non-activation of the acoustic or luminous signaling device of the transmitter (1), it means that there is no compress in the patient.
