Description

Technical Field

[0001] This utility model relates to the field of maxillary sinus lifting technology, specifically a maxillary sinus lifting tool. Background Technology

[0002] Maxillary sinus lift is a surgical procedure that involves surgically separating the bone wall and mucosa of the maxillary sinus on the inner side of the maxillary posterior teeth region, pushing the mucosa upwards, and implanting artificial bone material between the mucosa and bone wall. This restores the bone height of the maxillary posterior teeth region, achieving the goal of long-term stability of the implant.

[0003] The maxillary sinus lift tool is a tool used to lift the maxillary sinus. It uses the dissection part of its head to dissect the mucosa. However, the traditional maxillary sinus lift tools currently on the market have a dissection part that is too short to penetrate into the cavity, resulting in an insufficient range of mucosal dissection. Utility Model Content

[0004] The purpose of this invention is to provide a maxillary sinus lift tool to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are only used to explain the relevant content and are not intended to limit the present application. It should also be noted that, for ease of description, only the parts related to the present application are shown in the accompanying drawings.

[0024] It should be noted that, where there is no conflict, the embodiments and features described in this application can be combined with each other. The technical solutions of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways to implement the technical concept of this application in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concept of this application.

[0026] In the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0027] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0028] For descriptive purposes, this application may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0029] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0045] The working principle of this utility model is as follows:

[0046] In use, first grasp the handle 1 and extend the dissecting part 3 into the cavity inside the mouth. At this time, the dissecting head 22 first dissects a portion of the mucosa, separating a portion of the bone and mucosa in the cavity, allowing the instrument to enter part of the cavity first. Then, the pushing block 12 pushes the movable column 6 to slide in the movable cavity 5. The movable column 6 drives the elastic soft rod 7 to move in the guide groove 4. The elastic soft rod 7 drives the first folding arm 9 to move upward through the connecting block 8. The first folding arm 9 and the second folding arm 10 fold each other, so that the hinge of the first folding arm 9 and the second folding arm 10 extends out from the through groove 11, forming a longer dissection. At this time, under the action of the first spring 20, the insertion rod 15 is inserted into the insertion hole 16 to limit the movable column 6, thereby further expanding the dissection range of the mucosa. When the tool needs to be removed, press the pressing member 18. The pressing member 18 is partially inserted into the shrink groove 19. The pressing member 18 drives the insertion rod 15 to disengage from the insertion hole 16 through the connecting member 17. As a result, the movable column 6 is reset under the action of the second spring 21, and the first folding arm 9 and the second folding arm 10 are straightened. When the movable column 6 is reset to the limit position, the first folding arm 9 and the second folding arm 10 are still slightly protruding towards the groove 11.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
