Description

Technical Field

[0001] This invention relates to the field of respiratory medicine technology, and in particular to a thoracentesis positioning device for use in respiratory medicine. Background Technology

[0002] In the clinical diagnosis and treatment of respiratory diseases, thoracentesis is a common and important procedure. Its purpose is to remove effusion or gas from the pleural cavity to assist in the diagnosis of diseases and relieve patient symptoms. However, thoracentesis requires extremely high accuracy in localization. The precise puncture location not only affects the reliability of the diagnostic results but also directly impacts the patient's treatment outcome and safety.

[0003] Traditional methods of thoracentesis rely heavily on the experience of medical staff and simple surface landmarks to determine the puncture point, which has significant limitations. Firstly, due to individual patient differences, such as body size and chest shape, relying solely on surface landmarks makes it difficult to guarantee accuracy in every puncture, easily leading to deviations in puncture location, increased patient discomfort, and potential complications such as pneumothorax and hemothorax. Secondly, relying on experience for puncture location results in significant differences in technique between different medical staff, lacking standardization and precision, which negatively impacts the consistency and reliability of the puncture results.

[0004] Furthermore, while existing positioning devices improve accuracy to some extent, they are often complex in structure, cumbersome to operate, and require lengthy preparation times, which may delay treatment in clinical practice. Moreover, these devices struggle to achieve precise control when adjusting the position of puncture-related components, failing to meet the individualized needs of different patients. This limitation is particularly evident when dealing with special patients, such as those with scoliosis or other chest deformities, or children and the elderly with lower physical tolerance. Not only may they fail to accurately locate the optimal puncture point, but improper operation may also introduce additional risks and discomfort to the patient. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a thoracentesis positioning device for respiratory medicine, thereby solving the technical problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A thoracentesis positioning device for respiratory medicine includes a mounting frame. A positioning mechanism is fixedly mounted on the top of the mounting frame. The positioning mechanism includes a servo motor, which is fixedly mounted on the top of the mounting frame. A second gear is fixedly mounted on the side wall of the output shaft of the servo motor. A limit plate is fixedly mounted on the top of the mounting frame. A third gear is provided on the side wall of the second gear. A first damping telescopic rod is fixedly mounted inside the third gear. A magnetic coupler is fixedly mounted at the bottom of the first damping telescopic rod. A first gear is fixedly mounted at the bottom of the magnetic coupler. A second mounting plate is rotatably mounted at the bottom of the first gear. A fifth gear is rotatably mounted inside the second mounting plate. A fourth gear is fixedly mounted on the top of the fifth gear. A first synchronous belt drive assembly is driven and mounted on the side wall of the fifth gear. A rack is slidably mounted inside the second mounting plate. An electromagnet is installed inside the second mounting plate. A bidirectional lead screw is fixedly mounted at the output end of the servo motor. A second synchronous belt drive assembly is driven and mounted on the side wall of the bidirectional lead screw. The first mounting plate is threaded onto the side wall of the second synchronous belt drive assembly.

[0008] In one possible implementation, the servo motor output shaft is rotatably mounted inside the limiting plate, and the second gear is located above the limiting plate.

[0009] In one possible implementation, the third gear meshes with the second gear, and the first damping telescopic rod is rotatably mounted inside the limiting plate.

[0010] In one possible implementation, the rack meshes with a fifth gear, and a seat is slidably mounted above the first mounting plate.

[0011] In one possible implementation, a second damping telescopic rod is fixedly installed at the bottom of the seat, and a slider is fixedly installed at the bottom of the second damping telescopic rod.

[0012] In one possible implementation, the slider is slidably mounted on the bottom of the mounting bracket, and a U-shaped fixing block is fixedly mounted on the bottom of the rack.

[0013] In one possible implementation, an electric switch is fixedly mounted on the side wall of the mounting bracket, and an electric wire is fixedly mounted on the top of the electric switch.

[0014] In one possible implementation, the end of the wire away from the electrical switch is fixedly installed with an electromagnet, and a rotating plate is rotatably installed inside the U-shaped fixing block.

[0015] In one possible implementation, an illumination lamp is fixedly installed on the side wall of the rotating plate, and a damping distance measuring ruler is fixedly installed on the side wall of the rotating plate. The illumination lamp and the damping distance measuring ruler are located on opposite sides, and a ring is fixedly installed on the end of the damping distance measuring ruler away from the rotating plate.

[0016] In one possible implementation, a rotating cylinder is rotatably mounted inside the rotating plate, a perforated cylinder is fixedly mounted inside the rotating cylinder, a retaining ring is sleeved on the side wall of the rotating cylinder, a sponge ring is fixedly mounted at the end of the retaining ring away from the rotating plate, and a third damping telescopic rod is fixedly mounted at the bottom of the second mounting plate, with the bottom of the third damping telescopic rod fixedly mounted to the mounting frame.

[0017] Beneficial effects compared to existing technologies:

[0018] 1. In this solution, the illumination lamp projects a light ring to indicate the puncture site, making it easier for medical staff to quickly locate the puncture position. Furthermore, the coordinated movement of all components allows for precise adjustment of puncture-related parts to the appropriate position. For example, the multi-stage gear transmission and synchronous belt transmission assembly enable the rack to drive the U-shaped fixing block and rotating plate to the accurate position, making the operation convenient and improving the accuracy of puncture positioning.

[0019] 2. In this design, the damping telescopic rods and damping bearings, along with the second and third damping telescopic rods, play a supporting and buffering role. The second damping telescopic rod is located at the bottom of the seat. When a patient sits on the seat, the weight distribution and pressure exerted on the seat vary. The second damping telescopic rod can adaptively adjust its extension and retraction according to the pressure applied by the patient, providing just the right amount of support. This ensures the patient's sitting posture is stable and comfortable while effectively buffering vibrations caused by the patient's body movement or the movement of other components, avoiding unnecessary interference or discomfort to the patient. The third damping telescopic rod connects the second mounting plate to the mounting frame. During device operation, as the second mounting plate moves due to position adjustments, the third damping telescopic rod buffers the impact force during movement through its own extension and retraction, ensuring smooth movement of the second mounting plate and maintaining the stability of the entire device structure. When the rotating plate is adjusted to the accurate position for puncture, the damping bearing provides appropriate resistance, firmly holding the rotating plate in that position and preventing displacement due to minor external interference or accidental contact, thus ensuring accurate puncture positioning. When medical staff need to fine-tune the position of the rotating plate, it can rotate relatively flexibly to adapt to the individualized puncture needs of different patients, such as chest shape and puncture angle. Whether the patient is tall or short, broad or narrow, the device flexibly meets the body shape and puncture requirements of various patients while ensuring overall stability, providing reliable positioning support for thoracentesis.

[0020] 3. In this design, the application of a magnetic coupler ensures that even when the electromagnet attracts the rack and pinion, causing some components to appear stuck, the entire transmission system can still maintain a certain power state, preventing device failure due to localized jamming. This design achieves precise positioning and fixation of the puncture site while ensuring the reliability of the power transmission system, thus improving the overall performance and stability of the device.

[0029] Preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. However, the present invention can also be implemented in various different forms, and therefore the present invention is not limited to the embodiments described below. In addition, for the purpose of more clearly describing the present invention, parts not connected to the invention will be omitted from the drawings.

[0030] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0031] Example:

[0032] Please refer to Figures 1 to 6As shown, this embodiment introduces a thoracentesis positioning device for respiratory medicine, including a mounting frame 11. When in use, the patient is first guided to sit face down on the associated seat 26. A servo motor 12 is fixedly mounted on the top of the mounting frame 11. When the servo motor 12 is started, the servo motor 12 drives the second gear 13 to rotate counterclockwise.

[0033] A second gear 13 is fixedly installed on the side wall of the output shaft of the servo motor 12. A limit plate 14 is fixedly installed on the top of the mounting bracket 11. The output shaft of the servo motor 12 is rotatably installed inside the limit plate 14. The second gear 13 is located above the limit plate 14. The limit plate 14 restricts the third gear 16, so that the third gear 16 and the second gear 13 are always meshed.

[0034] The second gear 13 has a third gear 16 on its side wall. The second gear 13 drives the third gear 16 to rotate clockwise. The third gear 16 meshes with the second gear 13. The third gear 16 has a first damping telescopic rod 15 fixedly installed inside it (the first damping telescopic rod 15 has rectangles installed on both sides of a cylinder inside, and a groove is opened inside the outer side of a sleeve. The groove is shaped like a cylinder with rectangles installed on both sides). The third gear 16 drives the first damping telescopic rod 15 to rotate clockwise. The first damping telescopic rod 15 is rotatably installed inside the limiting plate 14. When the second mounting plate 41 and the first mounting plate 25 move respectively, the first damping telescopic rod 15 will extend to maintain the power transmission between the second gear 13, the third gear 16 and the magnetic coupler 17.

[0035] A magnetic coupler 17 is fixedly installed at the bottom of the first damping telescopic rod 15. The third gear 16 drives the magnetic coupler 17 to rotate clockwise. A first gear is fixedly installed at the bottom of the magnetic coupler 17, and the magnetic coupler 17 drives the first gear to rotate clockwise. A second mounting plate 41 is rotatably installed at the bottom of the first gear. The first gear drives the fourth gear 18 to rotate counterclockwise. A fifth gear 19 is rotatably installed inside the second mounting plate 41. The fourth gear 18 drives the fifth gear 19 to rotate counterclockwise. The fourth gear 18 is fixedly installed at the top of the fifth gear 19. A first synchronous belt drive assembly 21 is installed on the side wall of the fifth gear 19. Wheel 19 drives the first synchronous belt drive assembly 21 to rotate counterclockwise. A rack 22 is slidably installed inside the second mounting plate 41. The fifth gear 19 will cause the rack 22 to move towards the mounting bracket 11. The rack 22 and the fifth gear 19 mesh with each other. An electromagnet is installed inside the second mounting plate 41. When the light ring shines on the position to be pierced, the power switch 31 is pressed. The power switch 31 will supply power to the electromagnet through the wire. The electromagnet will firmly attract the rack 22, making it unable to move. At this time, the third gear 16 will be jammed. However, under the action of the magnetic coupler 17, the third gear 16 can rotate normally, while the first gear will no longer rotate.

[0036] A bidirectional lead screw 23 is fixedly mounted on the output end of the servo motor 12. Simultaneously, the servo motor 12 drives the bidirectional lead screw 23 to rotate counterclockwise. A second synchronous belt drive assembly 24 is mounted on the side wall of the bidirectional lead screw 23, driving the second synchronous belt drive assembly 24 to rotate counterclockwise. A first mounting plate 25 is threaded onto the side wall of the second synchronous belt drive assembly 24. Under the action of the bidirectional lead screw 23, the second mounting plate 41 and the first mounting plate 25 move from top to bottom and from bottom to top, respectively. A seat 26 is slidably mounted above the first mounting plate 25. The seat 26 can also slide on the first mounting plate 25. When the seat 26 slides, it drives the second damping extension... The telescopic rod 27 slides, and a second damping telescopic rod 27 is fixedly installed at the bottom of the seat 26. Simultaneously, the second damping telescopic rod 27 and the third damping telescopic rod 42 extend and retract respectively, supporting the seat 26 and the second mounting plate 41. A slider 28 is fixedly installed at the bottom of the second damping telescopic rod 27, driving the slider 28 to slide inside the mounting frame 11. The slider 28 is slidably installed at the bottom of the mounting frame 11. A U-shaped fixing block 29 is fixedly installed at the bottom of the rack 22. An electric switch 31 is fixedly installed on the side wall of the mounting frame 11. When in use, the light ring emitted by the irradiation lamp 33 will be positioned above the patient, and the light ring emitted by the irradiation lamp 33 is also used for puncture. The location is convenient for finding the puncture site. A wire is fixedly installed on the top of the electric switch 31, with the end of the wire away from the electric switch 31 fixedly installed to the electromagnet. A rotating plate 32 is rotatably installed inside the U-shaped fixing block 29. When the rotating plate 32 is adjusted to the position where the patient needs puncture, the retaining ring 38 is fastened to the side wall of the rotating cylinder 37, and the rotating plate 32 is rotated counterclockwise. A damping bearing exists between the rotating plate 32 and the U-shaped fixing block 29, so the rotating plate 32 will not easily rotate. An illumination lamp 33 is fixedly installed on the side wall of the rotating plate 32, and a damping distance measuring ruler 34 is also fixedly installed on the side wall of the rotating plate 32. The illumination lamp 33 and the damping distance measuring ruler 34 are located on opposite sides, with the damping distance measuring ruler 34 away from the rotating plate. A ring 35 is fixedly installed at one end of the rotating plate 32. A rotating cylinder 37 is rotatably installed inside the rotating plate 32. A perforated cylinder 36 is fixedly installed inside the rotating cylinder 37. A retaining ring 38 is sleeved on the side wall of the rotating cylinder 37. A sponge ring 39 is fixedly installed at the end of the retaining ring 38 away from the rotating plate 32. When the sponge ring 39 is in contact with the patient's skin, the rotating cylinder 37 is rotated to disinfect the puncture site. The ring 35 is pulled up, and the ring 35 drives the damping distance measuring ruler 34 to extend. The side wall of the damping distance measuring ruler 34 is marked with the value of how deep the puncture is. The needle is inserted into the perforated cylinder 36 and the patient is punctured. When the end of the needle is flush with the ring 35, the puncture reaches the depth marked by the damping distance measuring ruler 34.

[0037] The bottom of the second mounting plate 41 is fixedly installed with a third damping telescopic rod 42, and the bottom of the third damping telescopic rod 42 is fixedly installed with the mounting bracket 11.

[0038] Working principle: The device is based on the mounting frame 11. When in use, the patient is first guided to sit face down on the seat 26 associated with the mounting frame 11. At this time, the electric switch 31 fixedly installed on the side wall of the mounting frame 11 is in the unpressed state, the servo motor 12 fixedly installed on the top of the mounting frame 11 is not started, and all components are in the initial position. The illumination lamp 33 installed on the side wall of the rotating plate 32 emits a light circle. This light circle is above the patient, and its indicated position is the site for subsequent thoracentesis, which makes it convenient for medical staff to quickly find the puncture site.

[0039] When the servo motor 12 is started, its output shaft drives the second gear 13, which is fixed to its side wall, to rotate counterclockwise. The output shaft of the servo motor 12 is rotatably mounted inside the limiting plate 14, which is fixed to the top of the mounting bracket 11. The second gear 13 is located above the limiting plate 14, which restricts the position of the third gear 16, ensuring that the third gear 16 and the second gear 13 are always meshed. The third gear 16, meshing with the side wall of the second gear 13, rotates clockwise under the drive of the second gear 13. A first damping telescopic rod 15 is fixedly mounted inside the third gear 16. Its special structure (the inside is equivalent to a cylinder with rectangles on both sides, and the outside is equivalent to a sleeve with a groove, the groove being the shape of a cylinder with rectangles on both sides) allows the third gear 16 to drive the first damping telescopic rod 15 to rotate clockwise synchronously. The first damping telescopic rod 15 is rotatably mounted inside the limiting plate 14. When the second mounting plate 41 and the first mounting plate 25 move respectively, the first damping telescopic rod 15 extends, thus maintaining the position of the second gear 16. Stable power transmission between gear 13, third gear 16 and magnetic coupler 17. The magnetic coupler 17, which is fixedly installed at the bottom of the first damping telescopic rod 15, rotates clockwise with the rotation of the third gear 16 and the first damping telescopic rod 15. The first gear, which is fixedly installed at the bottom of the magnetic coupler 17, also rotates clockwise under the drive of the magnetic coupler 17. The bottom of the first gear is rotatably installed on the second mounting plate 41. The rotation of the first gear drives the fourth gear 18, which meshes with it, to rotate counterclockwise. The fourth gear 18 drives the fifth gear 19, which is rotatably installed inside the second mounting plate 41, to rotate counterclockwise. The fourth gear 18 is fixedly installed on the top of the fifth gear 19. The two rotate synchronously. The first synchronous belt drive assembly 21, which is driven by the fifth gear 19, performs counterclockwise transmission. At the same time, the rack 22, which meshes with the fifth gear 19, moves towards the mounting frame 11 under the drive of the fifth gear 19. At this time, the electromagnet installed inside the second mounting plate 41 is not energized and does not attract the rack 22.

[0040] As the components rotate, the light ring emitted by the illumination lamp 33 mounted on the rotating plate 32 moves. When the light ring accurately illuminates the puncture site, the medical staff presses the power switch 31. The wire fixedly mounted on the top of the power switch 31 conducts current to the electromagnet inside the second mounting plate 41. After the electromagnet is energized, it generates magnetic force, firmly attracting the rack 22 and preventing it from moving. At this time, since the rack 22 is fixed, the associated fifth gear 19, fourth gear 18 and first gear cannot continue to rotate, causing the third gear 16 to appear to be stuck. However, the magnetic coupler 17 plays a role, allowing the third gear 16 to still rotate normally relative to the first gear even when it is stuck. This ensures that when some components of the entire transmission system are fixed, other components can still maintain a certain power state, avoiding the failure of the entire device due to partial jamming.

[0041] While the aforementioned positioning is fixed, the bidirectional lead screw 23, fixedly installed at the output end of the servo motor 12, rotates counterclockwise under the drive of the servo motor 12. The second synchronous belt drive assembly 24, which is driven by the side wall of the bidirectional lead screw 23, rotates counterclockwise with the rotation of the bidirectional lead screw 23. A first mounting plate 25 is threadedly installed on the side wall of the second synchronous belt drive assembly 24. Under the action of the bidirectional lead screw 23 and the second synchronous belt drive assembly 24, the second mounting plate 25 moves from top to bottom, and the first mounting plate 25 moves from bottom to top. A seat 26 is slidably installed above the first mounting plate 25. A second damping telescopic rod 27 is fixedly installed at the bottom of the seat 26. As the seat 26 moves with the first mounting plate 25, the second mounting plate 26 moves from top to bottom. When the plate 25 moves, it can extend or compress as needed to support and cushion the seat 26. At the same time, the seat 26 can slide on the first mounting plate 25. The slider 28 fixedly installed at the bottom of the second damping telescopic rod 27 slides at the bottom of the mounting frame 11 when the seat 26 moves the second damping telescopic rod 27, ensuring the smoothness of the seat 26's movement. The third damping telescopic rod 42 fixedly installed at the bottom of the second mounting plate 41 compresses or extends when the second mounting plate 41 moves, supporting and cushioning the second mounting plate 41. It works in conjunction with the second damping telescopic rod 27 to ensure the stability of the entire device during the adjustment process.

[0042] A rotating plate 32 is rotatably mounted inside a U-shaped fixing block 29 fixedly installed at the bottom of the rack 22. When the rotating plate 32 is adjusted to the accurate position where the patient needs to be punctured, the retaining ring 38 is fastened to the side wall of the rotating cylinder 37, and then the rotating plate 32 is rotated counterclockwise. Because a damping bearing is installed between the rotating plate 32 and the U-shaped fixing block 29, the rotating plate 32 will not easily rotate and can be maintained in the adjusted position. The illumination lamp 33 fixedly installed on the side wall of the rotating plate 32 continues to indicate the puncture position. The damping distance measuring ruler 34 on the opposite side begins to function after the rotating plate 32 is adjusted into place. The rotating cylinder 37 rotatably mounted inside the rotating plate 32 has a perforation cylinder 36 fixedly installed inside it. The retaining ring 38, which is sleeved on the side wall of the rotating cylinder 37, has a sponge ring 39 fixedly installed at the end away from the rotating plate 32. When the sponge ring 39 is in contact with the patient's skin, the puncture site can be disinfected by rotating the rotating cylinder 37. After disinfection, the ring 35 fixedly installed at the end of the damping distance measuring ruler 34 away from the rotating plate 32 is pulled up, causing the damping distance measuring ruler 34 to extend. The side wall of the damping distance measuring ruler 34 is marked with the value of the puncture depth, providing a quantitative basis for the puncture operation. Finally, the needle is placed inside the perforation cylinder 36. When the end of the needle is flush with the ring 35, it indicates that the needle has punctured to the depth marked by the damping distance measuring ruler 34. At this time, the medical staff can perform the thoracentesis operation.

[0043] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
