Abstract

The curette invented belongs to the technical field of implantology and maxillofacial surgery. The shapes of curettes available on the market are designed so that the tip must be removed and changed to be able to file the different parts of the bone and eliminate infection following a dental extraction or to bleed the bone before inserting an implant. With this curette, which is traction-operated and has a 360° cutting edge, it is not necessary to change the tip in order to curette. The main advantages of using the curette are that: the blunt tip prevents damage to arteries, veins, nerves and membranes at the end of the cavity to be treated; the tips can be inserted into cavities made for inserting dental implants, to bleed the bone if necessary; the depth of the cavity can be measured during the curettage thereof because the curette is graduated in millimetres.

DESCRIPCIÓN DESCRIPTION

CURETA PARA HUESO DE EXTREMOS REDONDOS ROMOSBONE CURETTE OF ROMOS ROUND EXTREME

Y CON FILOS LATERALES EN 360°AND WITH 360 ° SIDE FILES

OBJETO DELA INVENCIÓNOBJECT OF THE INVENTION

La presente invención desarropa «na cureta quirúrgica de dos extremos activos que tenga en los dos extremos un elemento redondo romo, con ligera convexidad externa para que no dañe ias estructuras nobles que se puedan encontrar en el fondo dei lecho quirúrgico y además incorpora filos laterales en 360°. The present invention develops a surgical curette with two active ends having a blunt round element at both ends, with slight external convexity so that it does not damage the noble structures that can be found at the bottom of the surgical bed and also incorporates lateral edges in 360 °

ESTADO DE LA TÉCNICASTATE OF THE TECHNIQUE

Dado que, la presente invención supone un nuevo tipo de artículo o aparato en el mercado aún por desarrollar, se han investigado diferentes sectores técnicos para poder llevar a cabo dicha invención. Since, the present invention involves a new type of article or apparatus on the market yet to be developed, different technical sectors have been investigated in order to carry out said invention.

Actualmente no se encuentran curetas con filos laterales en 360° fondo convexo y romo que proteja las estructuras nobles que se puedan encontrar en el fondo de ios lechos quirúrgicos. Las que se encuentran actualmente disponibles en el mercado tienen una continuidad entre la parte de conexión y la parte activa que obliga a retirar continuamente las curetas y cambiarla por otra o girarla para poder raspar las distintas paredes del lecho quirúrgico. Currently there are no curettes with lateral edges in 360 ° convex and blunt bottom that protect the noble structures that can be found at the bottom of the surgical beds. Those that are currently available in the market have a continuity between the connection part and the active part that forces to continuously remove the curettes and change it for another or rotate it to be able to scrape the different walls of the surgical bed.

El nuevo diseño es mucho más práctico en este sentido ya que no hace falta remover la cureta dei lecho gracias a los 360° de sus filos laterales. The new design is much more practical in this regard since it is not necessary to remove the curette from the bed thanks to the 360 ° of its lateral edges.

Tampoco encontramos una que pueda utilizarse cómodamente dentro de ias pequeñas cavidades creadas para la inserción de! implante (tanto para la remoción de infecciones, remoción del períodonto, como para poder hacer sangrar el lecho quirúrgico u obtener pequeñas porciones de hueso autólogo del paciente). Nor do we find one that can be used comfortably within the small cavities created for the insertion of! implant (both for the removal of infections, removal of the periodontium, as well as to be able to bleed the surgical bed or obtain small portions of the patient's autologous bone).

La continuidad entre ios mangos, conexión y parte activa utilizados actualmente no hacen diferencia entre la conexión necesaria para trabajar cómodamente en el sector anterior y el sector posterior. The continuity between the handles, connection and active part currently used makes no difference between the connection necessary to work comfortably in the previous sector and the subsequent sector.

También la forma de la parte activa es totalmente diferente a ias utilizadas actualmente lo que le confiere al instrumento una practicidad .comodidad y seguridad mayores a las utilizadas actualmente. Also, the form of the active part is totally different from those currently used, which gives the instrument a practicality, comfort and safety greater than those currently used.

Hay que aclarar que lo que se intenta no es un reemplazo de ias utilizadas actualmente sí no una colaboración entre ambos diseños ya que las actuales son imprescindibles para trabajar con bordes afilados en el fondo del lecho quirúrgico cuando sea necesario.It should be clarified that what is being attempted is not a replacement for the currently used yes a collaboration between both designs since the current ones are essential to work with sharp edges at the bottom of the surgical bed when necessary.

EXHIBITION OF THE INVENTION

En ia cureta para hueso de extremos redondos romos y con filos laterales en 360° se distinguen tres zonas:In the bone curette with blunt round ends and with 360 ° lateral edges, three zones are distinguished:

=> La zona central o mango que tiene que ser antideslizante y recta con unos 10 centímetros de longitud aproximada => The central area or handle that has to be non-slip and straight with an approximate length of 10 centimeters

=> La zona de conexión entre el mango y ios extremos activos que mide unos 3 centímetros de longitud aproximadamente en cada extremo y puede ser recta o angulada para acceder correctamente al sitio de trabajo. Pudiendo estar milímetrada para saber exactamente la profundidad a la que se está trabajando. => The connection zone between the handle and the active ends that measures approximately 3 centimeters in length at each end and can be straight or angled to correctly access the work site. Being able to be millimeter to know exactly the depth at which it is working.

Los extremos que son convexos hacía afuera romos en la punta y con filos laterales en ios 360° de la circunferencia. Se fabrican en distintos diámetros para tener fácil acceso a diferentes lechos quirúrgicos, tanto para ia remoción de infecciones como para poder trabajar en el lecho impiantoiógico. Los diámetros podrían variar desde 2 milímetros hasta 8 milímetros. The ends that are convex outward blunt at the tip and with lateral edges at ios 360 ° of the circumference. They are manufactured in different diameters to have easy access to different surgical beds, both for the removal of infections and to be able to work in the impiantoiotic bed. The diameters could vary from 2 millimeters to 8 millimeters.

Esto comporta que el largo total de la cureta debería ser de unos 17 cm. aproximadamente. La cureta se fabricará en diferentes materiales usados actualmente en cirugía, tanto titanio como acero inoxidable quirúrgico. La misma no debe alterarse en los procesos de desinfección y tiene que poder esterilizarse y afilarse como las actuales para mantener correctamente su actividad en el tiempo. This means that the total length of the curette should be about 17 cm. approximately. The curette will be manufactured in different materials currently used in surgery, both titanium and surgical stainless steel. It should not be altered in the disinfection processes and must be sterilized and sharpened as the current ones to properly maintain its activity over time.

Dada la forma especial de los extremos, debemos realizar una fuerza de tracción para accionar la cureta lo que permite evitar lesiones en estructuras nobles (vasos, nervios y membranas) que hubiesen en el fondo de ia cavidad donde sea utilizada, garantizando así la máxima segundad posible en su uso. Evidentemente todas las cúrelas podrán fabricarse en distintas medidas y con distintas angutaciones en la zona de conexión dentro de tas medidas máximas y mínimas detalladas en los dibujos. Given the special shape of the ends, we must make a tensile force to actuate the curette, which avoids injuries to noble structures (vessels, nerves and membranes) that were at the bottom of the cavity where it is used, thus guaranteeing maximum safety. possible in its use. Obviously all the curelas can be manufactured in different sizes and with different angutations in the connection area within the maximum and minimum measures detailed in the drawings.

Lo realmente innovador y que lo configura como modelo de utilidad es el extremo por su pluñfuncionalídad, seguridad y su diseño que se adapta perfectamente a los lechos creados para la inserción de implantes y a los dejados por los dientes extraídos. What is really innovative and that configures it as a utility model is the extreme due to its functionality, safety and design that adapts perfectly to the beds created for implant insertion and those left by the extracted teeth.
