Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a visual nasal cavity dilation device. Background Technology

[0002] Endoscopic sinus surgery is a procedure performed using a high-resolution, angle-adjustable endoscope. First, the surgeon inserts a nasal dilator based on their hand preference and preference for their nostrils. The pressure from the instrument expands the soft tissue inside the nasal cavity, thereby improving nasal stenosis and allowing other surgical instruments to pass through the cavity and directly target the lesion. Then, one hand stabilizes the light source and the endoscope while the other hand continuously exchanges various specialized instruments to perform the procedure.

[0003] Endoscopic sinus surgery has grown from nothing to become one of the most important branches of rhinology. Nearly 20 years of exploration, popularization, and improvement have enabled surgeries on the nasal cavity and sinuses, especially deep ones, to be performed under direct vision. Direct vision results in less tissue damage, less bleeding, and a clear intraoperative field of view, which can help avoid some complications. While endoscopic sinus surgery has many advantages, it also has some disadvantages. The endoscope lens is easily contaminated by secretions and blood, affecting the field of view. This requires constant clearing of blood and secretions to maintain a clear view. Furthermore, the narrow nasal cavity limits the operating space, making repeated instrument changes inconvenient and potentially causing accidental nerve damage. Utility Model Content

[0004] In view of the above-mentioned shortcomings in the existing technology, the present invention provides a visual nasal cavity dilation device to solve the above-mentioned problems.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A visual nasal cavity dilation device includes a first blade and a second blade detachably connected to the first blade. Both the first blade and the second blade have multiple light-transmitting holes. The bottom of each light-transmitting hole has a step of different diameter. A visual structure for intranasal detection is installed in the light-transmitting hole.

[0007] Furthermore, the visualization structure is a light source installed inside the light-transmitting hole.

[0008] Furthermore, the visualization structure consists of a light source and an endoscope installed inside the light-transmitting hole.

[0009] Furthermore, an endoscope is installed in the light-transmitting hole on the first blade, and a light source is installed in the light-transmitting hole on the second blade.

[0010] Furthermore, both the first blade and the second blade are arc-shaped.

[0011] Furthermore, the first blade has a first connecting hole at its end, and the second blade has a second connecting hole at its end. Bearings are fitted into the first and second connecting holes to allow the first and second blades to be detachably connected.

[0012] Compared with the prior art, this utility model has the following advantages:

[0013] This invention relates to a visual nasal cavity dilator with a hollow blade structure that allows light to pass through. The light source or lens is installed inside the blade, and the light source is transmitted to the depths of the nasal cavity through the dilator. This device integrates the light source, endoscope, and dilator into one unit, achieving multiple functions in one device. It reduces the number of surgical instruments used, facilitates the operation, and effectively prevents blood and secretions from directly contaminating the lens. It creates a visual environment, allowing for clearer observation of the dilator's location and surrounding tissues, thus improving surgical precision. Compared to other dilators that can only dilate, this device has more comprehensive functions, making the diagnosis and treatment process more accurate and safer. Attached Figure Description

[0020] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0021] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0022] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0023] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example Example 1

[0024] like Figure 1 The diagram shows the structure of a visualized nasal cavity dilation device. To ensure the light source reaches deep into the nasal cavity, a highly translucent material is selected, preferably transparent PC or PVC. The device consists of a first blade 1, a second blade 2, and a bearing 3. The blade ends have a first connecting hole 4 and a second connecting hole 5, which are coaxial and connected by the bearing 3. Each blade has several light-transmitting holes 6. The diagram illustrates one possible configuration; the number of holes can be increased to accommodate different light sources, such as cold light sources or fiber optic light guides, to reduce the risk of thermal damage to patient tissues, allowing doctors to perform endoscopic examinations and surgeries more safely. To accommodate different light source models, the tips of the light-transmitting holes are designed with a gradually tapering diameter. Figure 2 As shown, light sources A and B are interference-fitted with diameters 2 and 3, respectively. In nasal surgery, the light source is first inserted into the aperture, ensuring an interference fit between the tip of the light source and the variable-diameter position of the aperture tip. Then, the dilator is inserted into the nasal cavity through the nostril. Figure 3 As shown, the surgical area is illuminated.

[0025] The visual nasal cavity dilation device proposed in this invention has multiple light source points evenly distributed on both blades, resulting in good light uniformity. This ensures that the light distribution in the illuminated area is uniform, avoiding the interference of shadows caused by a single light source on the judgment of the lesion site. It provides high-brightness illumination, ensuring that doctors have a clear and bright field of vision during the operation, enabling them to observe the details of the lesion more accurately and make precise judgments. This is of great significance for improving the surgical effect. Example 2

[0026] like Figure 4 As shown, based on Example 1 above, one of the light sources is replaced with an endoscope. Specifically, the endoscope is installed through the light-transmitting hole on the first blade, and the light source is installed through the light-transmitting hole on the second blade. The light source and endoscope work together. This structure integrates the light source, endoscope, and dilator into a single unit for one-time insertion, enabling visualization of the nasal cavity dilation device and providing the surgeon with a clear surgical field.

[0027] The difference between this example and the previous ones lies in the visualization. The lens is located inside the blade, avoiding contact with tissue and blood. The entire surgical process is clearly visible and easy to understand, allowing for more precise surgical results. Furthermore, by changing the endoscope from being passed through the dilator to being mounted on the side wall of the blade, the number of instruments in the surgical channel is reduced, giving the doctor more room to operate, reducing damage to tissues, and avoiding some complications.

[0028] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
