Description

Technical Field

[0001] This utility model relates to medical auxiliary devices, specifically a 3D-printed lung model for doctor-patient communication. Background Technology

[0002] Effective communication between doctors and patients is a primary means of resolving many existing doctor-patient conflicts. Currently, in preoperative communication for surgeries treating lesions inside the thoracic and abdominal cavities, such as pulmonary nodules, patients lack necessary physiological knowledge, and doctors lack intuitive means of demonstration. This leads to unclear, inadequate, and subjective communication. The common approach in current techniques is to use a standard model combined with the doctor's explanation to introduce the procedure to the patient, but due to individual differences, this communication is often limited. Summary of the Invention

[0003] The purpose of this invention is to provide a 3D-printed lung model for doctor-patient communication that can improve the accuracy and efficiency of doctor-patient communication.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this utility model is: a 3D-printed lung model for doctor-patient communication, comprising a lung model body 3D-printed based on the patient's lung data;

[0005] The lung model body includes a hollow lung lobe formed by splicing two mold flaps, a tracheal body 3D printed in different colors on the lung lobe, and a lesion body 3D printed in different colors on the lung lobe and / or tracheal body.

[0006] The lung lobe is also provided with at least one perforated observation port for observing the lesion.

[0007] Preferably, the edge of the mold piece is provided with a connecting edge along the splicing seam, and a magnetic adhesive strip is bonded and fixed on the connecting edge.

[0008] Preferably, the mold lobe is provided with a plurality of slots extending from the edge toward the center of the mold lobe, and a slot hole is provided at one end of the slot located in the center of the mold lobe.

[0009] It also includes a connecting rubber band, which includes a rib body. Each end of the rib body is provided with a clip and a short sleeve. The clip gradually increases in size from one end away from the rib body to the other end to form an expansion part. The size of the expansion part is larger than the size of the clip hole on the mold flap, and the size of the rib body is smaller than the size of the clip slot on the mold flap.

[0010] Preferably, the edge of the mold piece is provided with a plurality of 3D printed serrated patterns.

[0011] The beneficial effects of this invention are mainly reflected in the following aspects: Using actual lung data from patients for 3D printing, it can fully and intuitively display the spatial structure of lung lesions, facilitating accurate communication between doctors and patients; by using different colors to 3D print the lung lobes, trachea, and lesions separately, it can more clearly display the overall structure and features of the patient's lungs in a layered manner. This invention employs a two-lobed lung structure, which not only allows observation of the lesions after opening the two lobes, but also allows direct external observation through the perforated viewing port, enabling patients or their families to have a more comprehensive understanding of their condition, thus improving the efficiency of doctor-patient communication and reducing doctor-patient conflicts. Attached Figure Description

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 2 This is a schematic diagram of the structure for connecting rubber bands;

[0014] Figure 3 This is a structural diagram illustrating the application of multiple connecting rubber bands in combination. Detailed Implementation

[0015] like Figure 1-3 The illustration depicts a 3D-printed lung model for doctor-patient communication, primarily used in the diagnosis and treatment of lung diseases for communication with patients or their families, and also as a consultation and discussion model. This invention includes a lung model body 3D-printed based on the patient's lung data, which can be modeling data collected by high-precision diagnostic scanning equipment commonly used in hospitals, such as MRI and CT scans. Compared to traditional standard models, this model can be printed according to the patient's actual condition, making it more suitable for the patient's illness.

[0016] To facilitate communication and demonstration, the main body of the lung model of this utility model includes a hollow lung lobe 2 composed of two molded pieces 1 joined together. That is, the main body of the lung model consists of at least two molded pieces 1, but generally only two. When the lesion area is small and the number of lesions is limited, too many molded pieces 1 would be detrimental to the demonstration. It also includes a tracheal body 3 3D printed in a different color on the lung lobe 2, and a lesion body 4 3D printed in a different color on the lung lobe 2 and / or tracheal body 3. In other words, the tracheal body 3 is formed on the lung lobe 2, while the lesion body, depending on the actual situation, may be formed on the tracheal body 3 or the lung lobe 2. The lung lobe 2, tracheal body 3, and lesion body 4 are printed in different colors to distinguish the tissues. Often, since the lesion 4 is located inside the lung lobe 2 after assembly, at least one hollow observation port 5 for observing the lesion 4 can be opened on the lung lobe 2 for easy observation. The hollow observation port 5 is generally located near the lesion 4, but its opening does not occupy the display space of important related tissues near the lesion 4. It can be formed directly during printing or opened manually after printing, but the former is the main one.

[0017] Since the lung lobe 2 is composed of two molded pieces 1, to achieve good and stable assembly of the molded pieces 1, one possible method is to provide a connecting edge along the seam of the molded pieces 1 of the lung lobe 2, and to adhere and fix a magnetic strip to the connecting edge. In this method, because the connecting edge is directly formed by printing, secondary processing of the modeling data is often required, and more printing material is consumed.

[0018] Therefore, this utility model can also adopt the following approach: Figure 2 and 3 The connection shown in the diagram has several slots 6 extending from the edges towards the center of the mold segment 1. A locking hole 7 is provided at one end of the slot 6 located in the center of the mold segment 1. Generally, 2-3 slots and holes on each mold segment 1 are sufficient for a stable connection. Connecting the two mold segments 1 with a connecting rubber band is not only easy to handle but also relatively inexpensive.

[0019] like Figure 2 As shown, this utility model also includes connecting rubber bands, which can be used individually or in combination. To facilitate combination, this utility model employs connecting rubber bands with a specific structure, such as... Figure 2 As shown, the connecting rubber band includes a rib body 8, with a locking head 9 and a short sleeve 10 respectively provided at both ends of the rib body 8. The locking head 9 gradually increases in size from one end away from the rib body 8 to the other end to form an expansion portion 11. The size of the expansion portion 11 is larger than the size of the locking hole 7 on the lung lobe 2 mold flap 1, and the size of the rib body 8 is smaller than the size of the locking seam 6 on the lung lobe 2 mold flap 1.

[0020] In addition, to further improve the stability of the connection between the two mold pieces 1, several 3D printed serrated patterns can be provided on the edge of the mold piece 1. That is to say, the edge of the mold piece 1 is serrated, which can improve the stability after the two mold pieces 1 are joined. Of course, the serrations on the two mold pieces 1 should match.
