Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a CT-guided lung nodule localization needle. Background Technology

[0002] CT-guided percutaneous pulmonary nodule puncture and localization has become a common auxiliary procedure before thoracoscopic pulmonary nodule resection in clinical practice. Currently, there are numerous methods and techniques for preoperative localization of pulmonary nodules during thoracoscopic pulmonary nodule resection, such as the hookwire method. Nowadays, when pulmonary nodules need to be resected clinically, it is essential to use CT guidance and a localization needle for precise positioning of the pulmonary nodule to increase the accuracy of the pulmonary nodule resection surgery and thus minimize surgical trauma.

[0003] However, since some lung nodules are located in different places and require puncture at different angles, it is difficult to insert the needle into the lung nodule. Ordinary positioning needles need to be manually adjusted at the angle or a disposable guide is used to help determine the angle, which greatly reduces the success rate of fixing the positioning guidewire. This not only causes great trauma to the patient, but also increases the surgical risk of removing lung nodules and brings great inconvenience to the surgeon. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A CT-guided lung nodule localization needle includes a puncture needle, the puncture needle comprising a needle tube, a needle handle at the top of the needle tube, and a rotating assembly inserted into the top of the needle handle. The rotating assembly includes a limiting block, a rotating shaft, and a fixing sleeve. One end of the fixing sleeve has an insertion hole, and the needle handle is inserted into the insertion hole. The rotating shaft is sleeved on the other end of the fixing sleeve. The limiting block is located on the upper part of the rotating shaft, and a positioning component is fixedly installed on one side of the limiting block. The positioning component includes a U-shaped fixing plate and a support. The device comprises a plate, a vertical clamping plate, a horizontal clamping plate, a fixed shaft, and a protractor. The two ends of the U-shaped fixed plate are fixedly installed to the two ends of the limiting block. A support plate is welded to one side of the U-shaped fixed plate. One end of the vertical clamping plate is fixedly installed to both ends of the support plate. The two ends of the horizontal clamping plate are fixedly installed to the other end of the vertical clamping plate. The fixed shaft is fixedly installed in the middle of the horizontal clamping plate. The protractor is fixedly installed on the top of the fixed shaft. A clamping assembly is fixedly installed on the other side of the limiting block.

[0006] As an improvement to the above technical solution, the rotating assembly further includes a ring plate, which is fixedly installed in the middle of the limiting block and sleeved on the top of the rotating shaft.

[0007] As an improvement to the above technical solution, the limiting block has a waist-shaped slot in the middle, the rotating shaft is inserted into the middle of the waist-shaped slot, and the side wall of the limiting block has a limiting groove.

[0008] As an improvement to the above technical solution, the clamping assembly includes a bidirectional screw, a slider, and a limiting plate. The two ends of the bidirectional screw are provided with fixing blocks. The slider is symmetrically sleeved on both sides of the bidirectional screw. The limiting plate is fixedly connected to one side of the limiting plate and clamps the bottom of the rotating shaft.

[0009] As an improvement to the above technical solution, bolts are provided at both ends of the U-shaped fixing plate, and the bolts are used to fix the U-shaped fixing plate to both ends of the limiting block.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] A CT-guided lung nodule localization needle includes a puncture needle 1, which includes a needle tube 11. A needle handle 12 is located at the top of the needle tube 11. A rotating assembly 2 is inserted into the top of the needle handle 12. The rotating assembly 2 includes a limiting block 21, a rotating shaft 23, and a fixing sleeve 24. One end of the fixing sleeve 24 has an insertion hole 241, and the needle handle 12 is inserted into the insertion hole 241. The rotating shaft 23 is fitted onto the other end of the fixing sleeve 24. The limiting block 21 is located on the upper part of the rotating shaft 23. A positioning assembly 3 is fixedly installed on one side of the limiting block 21. The positioning assembly 3 includes a U-shaped fixing plate 31. The system includes a support plate 32, a vertical clamping plate 33, a horizontal clamping plate 34, a fixed shaft 35, and a protractor 36. The two ends of the U-shaped fixed plate 31 are fixedly installed to the two ends of the limiting block 21. The support plate 32 is welded to one side of the U-shaped fixed plate 31. One end of the vertical clamping plate 33 is fixedly installed to both ends of the support plate 32. The two ends of the horizontal clamping plate 34 are fixedly installed to the other end of the vertical clamping plate 33. The fixed shaft 35 is fixedly installed in the middle of the horizontal clamping plate 34. The protractor 36 is fixedly installed on the top of the fixed shaft 35. The clamping assembly 4 is fixedly installed on the other side of the limiting block 21.

[0022] In this embodiment, the limiting block 21 of the rotating component 2 works in conjunction with the rotating shaft 23 and the fixing sleeve 24 to achieve rotation of the puncture needle 1 within a specific range. The design of the limiting block 21 can limit the rotation angle of the puncture needle 1 and prevent damage caused by excessive rotation. The rotating shaft 23 is sleeved on the other end of the fixing sleeve 24, allowing the limiting block 21 and the positioning component 3 to rotate around the rotating shaft 23. One end of the fixing sleeve 24 has an insertion hole 241 for inserting the needle handle 12. The design of the fixing sleeve 24 can ensure a stable and reliable connection between the puncture needle 1 and the rotating component 2. The U-shaped fixing plate 31 of the positioning component 3 is fixedly installed at both ends of the limiting block 21, providing a stable support structure for the positioning component 3. The support plate 32 is welded to one side of the U-shaped fixing plate 31 to support the vertical clamping plate 33 and the horizontal clamping plate 34. The vertical clamping plate 33 and the horizontal clamping plate 34 are fixedly connected together to form a clamping structure for clamping the needle handle 12. The fixing shaft 35 is fixedly installed on the horizontal clamping plate. The middle of plate 34 provides support for protractor 36, which is fixedly mounted on top of fixed shaft 35. Protractor 36 is used to measure and display the angle of rotation of puncture needle 1, helping doctors to accurately control the angle during puncture and improve positioning accuracy. Clamping component 4 is used to clamp the bottom of rotating shaft 23 to ensure that these devices remain stable during puncture and do not interfere with the puncture operation. Through the combined use of rotating component 2 and positioning component 3, doctors can accurately control the angle and position of puncture needle 1, thereby improving the accuracy of lung nodule positioning. The design of rotating component 2 allows puncture needle 1 to rotate within a certain range to adapt to lung nodules of different positions and shapes. The design of positioning needle takes safety and reliability into consideration. Through a stable connection structure and precise measuring tools, safety and accuracy during puncture are ensured. By accurately controlling the angle and position of puncture needle 1, doctors can more effectively perform lung nodule resection surgery, thereby reducing damage to surrounding tissues and lowering surgical risks.

[0023] Specifically, the rotating assembly 2 also includes a ring plate 22, which is fixedly installed in the middle of the limiting block 21 and is sleeved on the top of the mounting shaft 23.

[0024] In this embodiment, the ring plate 22 is a circular plate structure, fixedly installed in the middle of the limiting block 21. The ring plate 22 provides a stable support surface for the limiting block 21 and the positioning component 3. Since the ring plate 22 is fixedly installed in the middle of the limiting block 21, it can ensure that the limiting block 21 will not deform or shift due to uneven force during rotation. The ring plate 22 is sleeved on the top of the rotating shaft 23, which limits the range of movement of the limiting block 21 and the positioning component 3 on the rotating shaft 23. By adjusting the cooperation relationship between the ring plate 22 and the rotating shaft 23, the rotation angle of the limiting block 21 and the positioning component 3 can be precisely controlled, thereby achieving precise control of the puncture needle 1. This makes the CT-guided lung nodule positioning needle more flexible and accurate in clinical applications. Doctors can precisely control the direction and depth of the puncture needle 1 by adjusting the angle and position of the rotating component 2 according to the patient's specific condition and surgical needs. This not only improves the accuracy and safety of the operation, but also reduces the surgical risk and the patient's pain.

[0025] Specifically, the limiting block 21 has a waist-shaped slot 211 in the middle, the rotating shaft 23 is inserted into the middle of the waist-shaped slot 211, and the side wall of the limiting block 21 has a limiting groove 212.

[0026] In this embodiment, the waist-shaped slot 211 is formed in the middle of the limiting block 21 to accommodate and support the rotating shaft 23, which increases the flexibility of the rotating component 2 and allows the limiting block 21 to be finely adjusted relative to the rotating shaft 23 to adapt to different operating requirements. The limiting groove 212 is formed on the side wall of the limiting block 21, and the limiting groove 212 creates a certain range of motion for the clamping component 4.

[0027] Specifically, the clamping assembly 4 includes a bidirectional screw 41, a slider 42, and a limiting plate 43. The two ends of the bidirectional screw 41 are provided with fixing blocks 411. The slider 42 is symmetrically sleeved on both sides of the bidirectional screw 41. The limiting plate 43 is fixedly connected to one side of the limiting plate 43, and the limiting plate 43 clamps the bottom of the rotating shaft 23.

[0028] In this embodiment, the two ends of the bidirectional screw 41 are provided with fixing blocks 411 to fix the bidirectional screw 41 to one side of the limiting block 21. The slider 42 is symmetrically sleeved on both sides of the bidirectional screw 41. The slider 42 is designed with threaded holes that match the threaded part of the bidirectional screw 41. When the bidirectional screw 41 rotates, the slider 42 will move along the axial direction of the bidirectional screw 41. The limiting plate 43 is threadedly connected to both sides of the slider 42. When the bidirectional screw 41 rotates, the slider 42 will drive the limiting plate 43 to move towards the middle, thereby clamping the rotating shaft 23.

[0029] Specifically, bolts 311 are provided at both ends of the U-shaped fixing plate 31, and bolts 311 are fixedly connected to both ends of the U-shaped fixing plate 31 and the limiting block 21. Fixing rods 331 are provided at both ends of the vertical clamping plate 33, and the vertical clamping plate 33 is symmetrically fixedly installed at both ends of the fixing rods 331.

[0030] In this embodiment, bolts 311 are provided at the ends of the two side walls of the U-shaped fixing plate 31. The bolts 311 pass through the holes of the U-shaped fixing plate 31 and are aligned with the corresponding holes on the limiting block 21. The bolts 311 are tightened with nuts, thereby firmly fixing the U-shaped fixing plate 31 to both ends of the limiting block 21. Fixing rods 331 are provided at both ends of the vertical clamping plate 33. The vertical clamping plate 33 is connected to the fixing rods 331 through the holes at both ends. The vertical clamping plate 33 is symmetrically fixed at both ends of the fixing rods 331 using the fixing rods 331. The U-shaped fixing plate 31 and the vertical clamping plate 33 together form a stable fixing structure for clamping the needle handle 12 of the puncture needle 1, which can ensure the stability and accuracy of the puncture needle 1 during the operation and also provide doctors with more flexible and accurate surgical operation methods.

[0031] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
