    [0001] ORAL SURGICAL RETRACTOR WITH PROTECTIVE ADDITION FOR TECHNIQUES
    [0002]
    [0003]
    [0004]
    [0005] OBJECT OF THE INVENTION
    [0006]
    [0007] The invention, as stated in the present specification, refers to an oral surgical retractor with protective attachment for particle projection techniques that provides, to the function to which it is intended, advantages and novelty characteristics, which are described in detail later, that suppose an improvement of the current state of the art.
    [0008]
    [0009] More specifically, the object of the invention focuses on an instrument for surgical use to separate the lips during the treatments of the oropharyngeal cavity, which has been conceived and carried out in order to obtain significant advantages over other existing instruments of analogous purposes. In particular, the instrument is equipped with an innovative structural configuration to maintain adequate lip retraction during treatments, ensuring patient comfort and correct access to the surgical field, expanding in the field of vision obtainable through conventional separators, without the other the party prevents its use in the later oral sectors if deemed necessary. The invention also includes an attachment that attaches to the retractor and protects the patient's face from the liquids in the form of a spray coming from the oral cavity during the performance of techniques that involve projection of particles which, in addition, reduces the risk of cross infection in the clinical environment.
    [0010]
    [0011] FIELD OF APPLICATION OF THE INVENTION
    [0012]
    [0013] The field of application of the present invention falls within the sector of the industry dedicated to the manufacture of sanitary instruments, more specifically that related to dental material, while covering the surgical field of various medical specialties, such as stomatology, surgery oral and maxillofacial, or otolaryngology.
    [0014] BACKGROUND OF THE INVENTION
    [0015]
    [0016] As is known, oropharyngeal cavity surgery has the function of preventing or correcting anatomical, evolutionary, traumatic and pathological defects of the oropharyngeal structures. All surgical intervention requires adequate access to the area to be treated to allow correct vision, thus reducing the duration of the intervention and the trauma inflicted on surrounding tissues. In addition, numerous oral therapeutic procedures, whether surgical or not, involve either the projection of particles or the generation of sprays. These elements sometimes fall on the patient's eyes or skin causing discomfort and / or health risks, as long as they are carriers of biological elements.
    [0017]
    [0018] Lip retraction has been carried out using two large groups of instruments:
    [0019]
    [0020] In a first group, the retraction requires the constant action of the clinician or auxiliary personnel by pulling lips and / or cheeks with hand instruments, such as dental mirrors, surgical separators or both simultaneously to ensure good access.
    [0021]
    [0022] The second group of existing instruments is elements that, based on the elasticity of the materials used in its construction, ensure a separation of the lips based on lateral or external orientation forces, depending on their configuration.
    [0023]
    [0024] The present invention provides obvious advantages over the first group of instruments as long as the continuous action of the operator or auxiliary is not necessary, thus freeing it for other tasks, while not preventing the use of surgical separators in subsequent sectors if necessary. . The advantages over the second group of retractors are evident, since it is an element that allows adequate access to soft tissues in the upper and lower incisors, which is not possible in retractors based on external orientation forces (they are supported intraorally over that area) and very difficult in those based on lateral orientation forces (they push the lips at the corners, which forces the soft tissue labial coverage in the previous sextants). As an additional advantage over both groups, the present invention incorporates the extraoral protection attachment which makes it manifestly superior to the alternatives existing in the market.
    [0025]
    [0026] Thus, although documents disclosing instruments of the type concerned herein are known in the state of the art, none describes the present invention as claimed. In particular, as closer, those described in patents US6500002B2, CN202960443 (U), CN202740152U, US4200089A and DE422782C can be cited, since they consist of open retractors formed by two lateral elements joined together by a connecting element, however all they are provided in the mentioned lateral elements with a single channel for their adaptation to the lips, instead of two with which the retractor of the present invention has and, on the other hand, none incorporates a protective attachment, which, although described In other documents, such as in patents US4721465A, US4344758A or ES2103776, it also constitutes an innovative element with respect to those disclosed in said documents, thanks to the fact that it attaches to the retractor and the malleable guides that it has to adapt it on the patient's face .
    [0027]
    [0028] EXPLANATION OF THE INVENTION
    [0029]
    [0030] The oral surgical retractor with protective attachment for particle projection techniques that the invention proposes is thus configured as a novelty within its field of application, since according to its implementation and in a restrictive way the previously stated objectives are satisfactorily achieved , the characterizing details distinguishing it conveniently included in the final claims that accompany the present description.
    [0031]
    [0032] More specifically, what the invention proposes, as noted above, is an instrument for surgical use to separate the lips, which also comprises a protective attachment.
    [0033]
    [0034] The invention is thus configured by two independent parts, a constituent of the retractor, consisting of a monobloc body of elastic and autoclavable material that, applied on the lips, maintains its separation, while externally pulling the most anterior portion of the cheeks.
    [0035]
    [0036] The second piece consists of a protective attachment that is incorporated into the retractor once placed, being formed by an impermeable laminar element, preferably disposable, which is also reinforced with malleable guides, preferably made of soft metal rods, which allow to adequately model the protection on the patient's face, sticking to the first piece, that is to say the retractor, by means of an elastic rubber integrated in said laminar body.
    [0037]
    [0038] The set of the invention that form said retractor and the protective attachment has important contributions against what is known in terms of the group of lip retractors based on lateral orientation forces, specifically referring to the fact that the labial separation is carried out completely and comfortably, facilitating access to both subsequent and previous sectors, as well as providing a new element of protection that does not exist in the market to date.
    [0039]
    [0040] For this, the retractor is based on the common structure of the retractors of this group, in the sense that the piece that forms it comprises a lower element in the form of an ellipse half in charge of joining the side elements together, where the lips are coupled and that, being deformed, provide the lateral forces necessary for labial retraction by virtue of the elastic properties of the material used for its construction.
    [0041]
    [0042] As with the retractors of this group, the lateral elements intended to push the corners describe a partially elliptical curve and have a groove to accommodate the lips, whose intraoral side edges in their middle third are significantly larger than those that would remain outside the mouth, to be partially equalized as they reach the upper and lower areas of the retractor, in order to ensure the stability of the retractor and prevent it from being ejected when the mouth is closed.
    [0043]
    [0044] Well, from this already known configuration, the particularities of the present invention begin in the form of these lateral sectors, because at their upper and lower ends, the grooves intended to accommodate the lips follow an upward and outward path, deviating from the initial ellipse to ensure the separation of the lips of the incisors.
    [0045]
    [0046] In any case, the retractor is especially distinguished because it includes a second groove, housed on the extraoral face of the model and of smaller size but equal length, designed to house the protective attachment, which is inserted in it and is kept in position using an integrated elastic band. This rubber, in turn, ensures a tensile force towards the center of the ellipse described by the lateral elements of the retractor, with a component with intraoral direction, which induces a rotation in the lateral sectors, more evident in the areas farthest from the center of the ellipse, and thus contributing to a better separation in the area of the cheeks.
    [0047]
    [0048] The protective attachment is a laminar piece, preferably, it is disposable, which is made up of three bonded layers: a waterproof interior and two absorbent (upper and lower) exteriors, to avoid the concretion of spray liquid, in drops and its subsequent displacement, as well as avoiding the accumulation of drops on the face due to the perspiration of the patient.
    [0049]
    [0050] The attachment also has malleable material guides, preferably metal, that leave radially from a central opening (which gives access to the mouth and is surrounded by the elastic rubber with which it is attached to the retractor) towards the ends. These malleable guides allow the piece to be shaped and placed in the desired position, once placed in the retractor, so that it does not interfere with the clinical work and limits the spray projection outside the operative field, in addition to protecting the patient's face.
    [0051]
    [0052] The described oral surgical retractor with protective attachment for particle projection techniques represents, therefore, an innovation of structural and constitutive characteristics unknown until now, reasons that together with its practical utility, provide it with sufficient foundation to obtain the privilege of exclusivity that is request.
    [0053]
    [0054] DESCRIPTION OF THE DRAWINGS
    [0055]
    [0056] To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, this descriptive report is attached, as an integral part thereof, of a set of drawings in which with an illustrative and non-limiting the following has been represented:
    [0057]
    [0058] Figure number 1.- Shows a schematic view in front perspective of an example of the oral surgical retractor object of the invention, its general configuration and the main parts comprising, specifically the lateral elements and the connecting element being appreciated.
    [0059] Figure number 2.- Shows a plan view of the example of the oral surgical retractor of the invention shown in figure 1, in particular the configuration of the two grooves presenting the lateral elements, for the lips and for holding the protective attachment .
    [0060]
    [0061] And figure number 3.- Shows an elevation view of an example of the protective attachment comprising the invention, its configuration and main parts being appreciated.
    [0062]
    [0063] PREFERRED EMBODIMENT OF THE INVENTION
    [0064]
    [0065] In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a non-limiting embodiment of the recommended oral surgical retractor can be observed, which comprises the parts and elements indicated and described in detail below.
    [0066]
    [0067] Thus, as observed in said figures, the retractor (1) in question, consisting of a piece of elastic and autoclavable material comprising a central lower element (2) responsible for joining two lateral elements (3) together, where the lips are coupled, it is distinguished by having two grooves, in said lateral elements (3), one in the intraoral or posterior face (4), to couple the lips, and another in the extraoral or anterior face (5) in which is coupled a protective attachment (6) consisting of a piece independent of the retractor (1) formed by a laminar element with a central hole (7) whose edges fit into said anterior groove (5), and which is reinforced with malleable guides (8), which allow modeling its shape and position to adapt the protection it provides on the patient's face.
    [0068]
    [0069] Preferably, this protective attachment (6) is attached to the retractor (1) by being attached to it by means of an elastic band (9) integrated in the edge of the aforementioned central hole (7) of the attachment and which conforms to the anterior groove (5) of the retractor (1) provided for this purpose.
    [0070]
    [0071] Preferably, the laminar element constituting the protective attachment (6) is disposable, and is made up of three bonded layers: a waterproof interior and two absorbent (upper and lower) outer layers. And for its part, also preferably, the guides (8) incorporating said attachment (6) are soft metal rods, and are arranged so that they leave radially from the central hole (7) towards the ends.
    [0072] Finally, it should be noted that, in the preferred embodiment, the respective upper (4a) and lower (4b) ends of the grooves of the intraoral or posterior face (4) of both lateral elements (3) of the retractor (1), intended for lodge the lips, follow a path that deviates up and out of the imaginary line (t) that would follow
    [0073] the trajectory of the ellipse that initially defines the curve they present in its central part, causing the lips to separate from the incisors.
    [0074]
    [0075] Describing sufficiently the nature of the present invention, as well as the way of putting it into practice, it is not considered necessary to make its explanation more extensive so that any person skilled in the art understands its scope and the advantages that derive from it, stating that, within its essentiality, it may be carried out in other embodiments that differ in detail from that indicated by way of example, and to which it will also achieve the protection that is sought provided that it does not alter, change or modify its fundamental principle .
