Description

Technical Field

[0001] This utility model relates to the field of auxiliary positioning technology, specifically a CT-guided auxiliary positioning device for lung nodules. Background Art

[0002] Pulmonary sarcoidosis is a multi-system, multi-organ granulomatous disease of unknown etiology, commonly affecting the lungs, bilateral hilar lymph nodes, eyes, skin, and other organs. Chest involvement rates are as high as 80%–90%.

[0003] A search revealed a Chinese utility model patent, CN217938332U, which discloses an auxiliary positioning device for CT-guided lung nodules. This device includes a mesh pad, a flexible rod, a soft rubber strip, and adhesive tape. The mesh pad is formed by multiple interwoven longitudinal and transverse lines. The ends of the mesh pad are fixed to the soft rubber strip. The soft rubber strip is located at the bottom of the flexible rod. The flexible rod is inserted into the soft rubber strip. A retainer is provided between the two ends of the two soft rubber strips. The two retainers are arranged in parallel. The adhesive tape is fixed to the retainers. The advantage of this application is that it provides an auxiliary positioning device for CT-guided lung nodules, which uses adhesive tape to fix the soft rubber strip to the patient's body surface, thereby allowing the doctor to determine the needle insertion point on the body surface before lung nodule surgery using the mesh pad formed by interwoven longitudinal and transverse lines.

[0004] However, when the device comes into contact with the patient's body, the mesh pad changes shape with the patient's body during use, causing discomfort to the patient. In addition, the device lacks the function of adjusting the internal distance of the mesh pad. When a large area needs to be punctured for biopsy, surgical resection, or ablation treatment, and the internal distance of the mesh pad is too small, it may be impossible to puncture or perform surgery in a timely manner.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A CT-guided lung nodule auxiliary positioning device includes a clamp 1. A first connecting rod 2 is fixedly connected to one side of the front of the clamp 1. A connecting groove 3 is opened inside the first connecting rod 2, and a first bolt 4 is engaged inside the connecting groove 3. A second connecting rod 5 is fixedly connected to one side of the back of the clamp 1. A sliding groove 6 is opened at the bottom of the front of the clamp 1, and a rubber pad 7 is engaged inside the sliding groove 6. A threaded groove 8 is opened on one side of the top of the clamp 1, and a second bolt 9 is engaged inside the threaded groove 8. A first handle 10 is fixedly connected to the top of the second bolt 9. The device is configured by the first connecting rod 2, the second connecting rod 5, the first bolt 4, and a first nut 13. Both the first connecting rod 2 and the second connecting rod 5 have connecting grooves 3 inside. When the two clamps move, the first nut 13 is in the groove, so that there is no jamming during movement.

[0024] In this embodiment, preferably, a fixing groove 11 is provided on one side of the bottom end of the clamp 1, and a sponge pad 12 is fixedly connected to the outer surface of the fixing groove 11. By setting the sponge pad 12, the cushioning can be reduced when in contact with the patient, while protecting the patient's skin.

[0025] In this embodiment, preferably, the second connecting rod 5 is internally engaged with a first bolt 4, and one end of the first bolt 4 is threadedly connected to a first nut 13. With the first bolt 4, the first nut 13, the first connecting rod 2, and the second connecting rod 5 in this configuration, when the two clamps are moved and adjusted, the first bolt 4 is engaged in the first connecting rod 2 and the second connecting rod 5, making left and right adjustments quick and convenient, while the first nut 13 is used for fixing.

[0026] In this embodiment, preferably, screw grooves 14 are provided on both sides of the top of the rubber pad 7, and a second bolt 9 is engaged inside the screw groove 14. After the rubber pad 7 has been used with a patient, the second bolt 9 can be rotated to clean and replace the rubber pad 7, thus avoiding infection.

[0027] In this embodiment, preferably, the sliding groove 6 has a rotating groove 15 inside, and a second bolt 16 is engaged inside the rotating groove 15. Through the rotating groove 15 and the second bolt 9, the rotating groove 15 is threadedly connected to the second bolt 9, so that the rubber pad 7 and the clamp 1 are integrated.

[0028] In this embodiment, preferably, the rubber pad 7 has a rod groove 16 inside, and a rubber rod 17 is inserted inside the rod groove 16. Through the rod groove 16 and the rubber rod 17, the rubber pad 7 has a plurality of rod grooves 16 inside. If the area between them is too small, the rubber rod 17 can be detached from them.

[0029] This embodiment of a CT-guided lung nodule auxiliary positioning device allows medical staff to adjust the distance between the two clamps 1 according to the patient's body size. The medical staff can loosen the first nut 13, causing the first bolt 4 to move back and forth inside the first connecting rod 2 and the second connecting rod 5, allowing the patient to be clamped in the fixing groove 11. The sponge pad 12 protects the patient's skin and reduces cushioning. The first connecting rod 2 and the second connecting rod 5 are then fixed by the first nut 13. Simultaneously, the rubber pad 7 can be stretched. The medical staff can rotate the first handle 10 and the second bolt 9 to attach the rubber pad 7 to the sliding groove 6. It can be removed after one patient's use to avoid infection. After the location is determined by CT, if the area is too large, the rubber rod 17 can be removed from the rubber pad 7 to avoid excessively large resection areas and the inability to adjust the distance between the rubber rods 17 in a timely manner.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. 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 preferred examples and are not intended to limit the utility model.
