Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a 3D-printed navigation guide plate for locating lung ground-glass nodules. Background Technology

[0002] Lung nodule localization and navigation guides combine patient CT data with real-time surgical images to provide surgeons with precise visual guidance, helping to quickly and accurately locate lung nodules during surgery, especially suitable for nodules that are located deep or small. It not only reduces surgical time and radiation exposure but also avoids damage to surrounding tissues, improving the safety and success rate of the surgery, making it an important auxiliary tool in minimally invasive lung nodule surgery.

[0003] Existing positioning and navigation guides are all integrally formed by 3D printing and then fixed to the patient's body to position and guide the puncture needle. However, existing navigation guides are prone to loosening after fixation. In addition, during the puncture process, different diameter puncture needles need to be selected according to different lesions. Existing navigation guides need to be printed according to different diameter puncture needles, thus wasting their work efficiency.

[0004] Therefore, this invention provides a 3D-printed pulmonary ground-glass nodule positioning and navigation guide plate to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing positioning and navigation guides are all integrally formed by 3D printing and then fixed on the patient's body to position and navigate the puncture needle. However, existing navigation guides are prone to loosening after fixing. At the same time, during the puncture process, different diameter puncture needles need to be selected according to different lesions. Existing navigation guides need to be printed according to different diameter puncture needles, which wastes their work efficiency.

[0006] This utility model provides the following technical solution: a 3D-printed pulmonary ground-glass nodule positioning and navigation guide plate, including a fixing plate, a fixing suction cup, a limiting hole, and an adjustment device. The fixing plate is set as a triangle that conforms to the structure of the human body. The fixing plate is provided with fixing suction cups around its perimeter. The fixing plate is provided with a limiting hole for limiting the position at its center. An adjustment device is installed in the limiting hole. The adjustment device is used to fine-tune the puncture needle inserted into the limiting hole, thereby ensuring the accuracy of its puncture.

[0007] Preferably, the adjusting device includes a fixing rod, a fixing ring, a limiting groove, a locking block, and a locking buckle. The fixing rod array is installed in the limiting hole, the fixing ring is installed at the end of the fixing rod, the limiting groove corresponding to the fixing rod is installed on the outer side of the fixing ring array, the locking block is provided in the limiting groove, and the locking buckle is provided on the fixing rod.

[0008] Preferably, the fixing plate is provided with an adhesive groove for placing the fixing strap.

[0009] Preferably, the fixing plate has a double-layer hollow structure, and an anti-slip rubber pad is provided on the side closest to the skin.

[0010] Preferably, the fixing ring is provided with a sensor for sensing the puncture needle.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention uses an adjustment device to fix the fixing ring through the cooperation between the limiting groove and the fixing rod. Simultaneously, because the fixing ring has a limiting groove and a locking block on its outer side, and the fixing rod has a locking buckle, the fixing ring is locked by the cooperation between the locking block and the locking buckle. This detachable connection allows for the replacement of the puncture needle during the puncture process in conjunction with CT scans. That is, when a different puncture needle size needs to be changed under CT visualization, simply remove the fixing ring from the fixing rod and replace it with the corresponding size. This method avoids the need to print navigation guides for different diameter puncture needles when different lesions require different diameter needles during the puncture process, thus improving work efficiency.

[0023] The present invention aims to address the problem that existing positioning and navigation guides are integrally formed by 3D printing and then fixed to the patient's body for positioning and navigation of puncture needles. However, existing navigation guides are prone to loosening after fixing. In addition, during the puncture process, different diameter puncture needles need to be selected according to different lesions, and existing navigation guides need to be printed according to different diameter puncture needles, thus wasting their work efficiency. In view of this, this disclosure proposes a 3D-printed navigation guide for locating lung ground-glass nodules. An adjustment device is used to fix the fixed ring through the cooperation between the limiting groove and the fixing rod. Simultaneously, a limiting groove and a locking block are provided on the outer side of the fixed ring, and a locking buckle is provided on the fixing rod. The locking ring is locked through the cooperation between the locking block and the locking buckle. This detachable connection allows for the replacement of the puncture needle during the puncture process in conjunction with CT scans. That is, when a different puncture needle size needs to be used under CT visualization, simply remove the fixed ring from the fixing rod and replace it with the corresponding size. This method avoids the need to print navigation guides for different diameter puncture needles depending on the lesion during the puncture process, thus improving work efficiency.

[0024] like Figures 1 to 4 As shown, a 3D-printed pulmonary ground-glass nodule positioning and navigation guide plate includes a fixing plate 1, a fixing suction cup 2, a limiting hole 3, and an adjustment device 4. The fixing plate 1 is set as a triangle that conforms to the structure of the human body. The fixing suction cup 2 is arranged around the fixing plate 1. The limiting hole 3 for limiting is arranged at the center of the fixing plate 1. The adjustment device 4 is installed in the limiting hole 3. The adjustment device 4 is used to fine adjust the puncture needle inserted into the limiting hole 3, thereby ensuring the accuracy of its puncture.

[0025] The fixing ring 42 is fixed by means of the adjustment device 4 through the cooperation between the limiting groove 43 and the fixing rod 41. At the same time, the fixing ring 42 is provided with a limiting groove 43 and a locking block 44 on the outside, and the fixing rod 41 is provided with a locking buckle 45. The fixing ring 42 is locked by the cooperation between the locking block 44 and the locking buckle 45. This detachable connection allows for the replacement of the puncture needle model during the puncture process in conjunction with CT. That is, when a different specification of puncture needle needs to be replaced under CT visualization, it is only necessary to remove the fixing ring 42 from the fixing rod 41 and replace it with a fixing ring 42 of the corresponding size. The above method avoids the need to print navigation guide plates according to different diameter puncture needles when different diameter puncture needles are selected according to different lesions during the puncture process, thereby improving work efficiency.

[0026] like Figures 1 to 3As shown, the adjusting device 4 includes a fixing rod 41, a fixing ring 42, a limiting groove 43, a locking block 44, and a locking buckle 45. The fixing rod 41 is arranged in an array inside the limiting hole 3. A fixing ring 42 is installed at the end of the fixing rod 41. A limiting groove 43 corresponding to the fixing rod 41 is arranged in an array outside the fixing ring 42. A locking block 44 is provided in the limiting groove 43. A locking buckle 45 is provided on the fixing rod 41.

[0027] The locking ring 42 is locked by the cooperation of the locking block 44 and the locking buckle 45. This detachable connection allows for the replacement of the puncture needle model during the puncture process in conjunction with CT. That is, when it is necessary to replace the puncture needle with another specification under the CT display, it is only necessary to remove the fixing ring 42 from the fixing rod 41 and replace it with a fixing ring 42 of the corresponding size to achieve the work of limiting and guiding puncture needles of different diameters.

[0028] like Figures 1 to 4 As shown, the fixation plate 1 is provided with an adhesive groove 11 for placing the fixation strap. By providing the adhesive groove 11, the fixation strap can pass through the adhesive groove 11 and thus fix the fixation plate 1 to the patient's body. In conjunction with the suction cup, the fixation plate 1 can be firmly fixed to the human body, thereby achieving better navigation and positioning, and avoiding displacement of the fixation plate 1 during the puncture process, which would affect the puncture effect.

[0029] like Figure 4 As shown, the fixation plate 1 has a double-layer hollow structure, and an anti-slip rubber pad 12 is provided on the side closest to the skin. The double-layer hollow structure effectively reduces the weight of the fixation plate 1 while providing good breathability and heat dissipation, avoiding discomfort to the patient caused by pressure from the fixation plate 1 during puncture. In addition, the hollow design enhances the fit of the fixation plate 1, allowing it to better adapt to the curvature of the human body, thereby improving the stability of the fixation plate 1. The anti-slip rubber pad 12 on the side closest to the skin further enhances the friction between the fixation plate 1 and the skin, preventing the fixation plate 1 from shifting during puncture, thus ensuring the accuracy and safety of the puncture.

[0030] like Figure 3 As shown, a sensor 421 for sensing the puncture needle is provided inside the fixing ring 42. The sensor 421 monitors the position and status of the puncture needle in real time, which can significantly improve the accuracy and efficiency of puncture.

[0031] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
