Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a thoracic cavity tube fixation stent for cardiothoracic surgery. Background Technology

[0002] In the field of cardiothoracic surgery, postoperative patient care after thoracic surgery is a complex and meticulous process, in which the fixation and management of thoracic tubes is a crucial aspect. Thoracic tubes, such as drainage tubes and urinary catheters, not only serve the important functions of draining fluid and monitoring the patient's condition, but the appropriateness of their fixation method directly affects the patient's comfort, recovery speed, and the incidence of postoperative complications. For example, Chinese patent application CN218871033U discloses a thoracic tube fixation stent for cardiothoracic surgery. This patent allows for adjustment of the stent's position by moving a movable block, which in turn moves a clamp, facilitating adjustment by medical staff according to the patient's chest cavity location.

[0003] Pipe fixing supports like these typically only provide basic fixing functions and lack flexibility and adaptability.

[0004] First, although the stent in the aforementioned patent can meet the adjustment requirements for height and angle to a certain extent, its main structure is made of rigid materials. This means that in practical applications, especially in complex medical scenarios, it is impossible to arbitrarily bend or adjust the fixed path of the tube according to the patient's specific position, surgery or treatment needs.

[0005] Secondly, existing technologies for adjusting the pipe fixing points are often limited to fine-tuning or simple rotation of fixed positions, failing to achieve truly arbitrary adjustments and rotations. This limitation not only increases the difficulty of operation for medical staff but also may lead to safety hazards such as pipe detachment or twisting due to insecure fixing or improper adjustment, affecting the patient's treatment outcome and comfort.

[0006] Furthermore, with the continuous advancement of medical technology, real-time monitoring of patient conditions has become an essential component of modern medical care. However, most existing medical stents only provide physical support and lack the ability to monitor the patient's fluid and physical condition in real time. If abnormalities in fluids or the patient's body could be detected promptly during the drainage process, rapid rescue and treatment could be initiated. This lack of information makes it difficult for medical staff to promptly grasp changes in the patient's condition, potentially delaying treatment or affecting its effectiveness. Summary of the Invention

[0007] The purpose of this invention is to provide a thoracic tube fixation stent for cardiothoracic surgery, which can adjust the height and orientation of the device according to needs, as well as the position, path, and orientation of the tube during fixation.

[0025] The moving component, lifting component, and rotating component of this invention can adjust the height and orientation of the device according to needs, and can freely control the movement or fixation of the device. In the normal state, the support part of the moving component fixes the support rod. When movement is required, the rolling part of the moving component is rotated downward so that the rolling part contacts the ground surface to assist the device in moving. When adjusting the height, it is only necessary to rotate the driving part of the lifting component to drive the lifting and lowering part of the lifting component to adjust the height. At the same time, rotation can also drive the rotating component to perform positioning rotation, thereby improving the applicability and versatility of the device.

[0026] The fixation component of this invention allows for adjustment of the tube fixation position as needed, and the positioning path and orientation of the tube during fixation can be freely adjusted to improve patient comfort. During tube fixation, the fixation path can be bent as needed to customize the required fixation path. Then, the positioning component is moved and positioned as required. Subsequently, the thoracic tube is placed in the center of the clamping component and clamped and fixed by the clamping part of the clamping component. Simultaneously, the main body of the clamping component is rotated to adjust the tube's orientation, and fixation is performed after adjustment. This allows for diverse fixation methods for the thoracic tube, improving patient comfort and the applicability of the device.

[0027] The detection component and cannula of this invention can detect the drainage of pleural fluid in a timely manner and monitor the patient's physical condition in real time to improve safety. During the construction of the pleural tube, the tube is connected to the inlet and outlet of the cannula, and the skin-contact part of the detection component is fixed at the end of the tube and in contact with the patient's body surface. At this time, the skin-contact part will detect the patient's body temperature and pleural pressure. At the same time, when the fluid in the pleural cavity is drained, it will also be observed and detected through the cannula, which facilitates the timely detection of adverse conditions and improves the efficiency of treatment.

[0045] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0046] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in a preferred embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0047] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include the three-dimensional spatial dimensions of length, width, and depth.

[0048] Please see the appendix Figures 1-14 As shown, this embodiment provides a thoracic surgery nursing thoracic cavity tube fixation stent, including a support rod 10, with a sleeve 11 fixedly connected to the middle of the support rod 10;

[0049] Adjustment component 20 includes a moving component 21 disposed at the bottom of support rod 10, a lifting component 22 disposed in the inner cavity of support rod 10, and a rotating component 23 disposed at the top of lifting component 22.

[0050] The fixing component 30 includes a bending component 31 disposed on the top of the rotating component 23, a positioning component 32 slidably connected inside the bending component 31, and a clamping component 33 disposed at the bottom of the positioning component 32.

[0051] Detection component 40 is disposed on the rotating component 23 and the sleeve 11;

[0052] When the thoracic tube is clamped by the clamping component 33, the positioning component 32 slides along the bending component 31 to adjust the position of the clamping component 33. The bending component 31 is used to change the path and orientation of the positioning component 32.

[0053] The detection component 40 is used to detect fluid in the pleural tube and the patient's body, and the moving component 21 is used to control the movement or fixation of the device.

[0054] It should be noted that the main body of the cannula 11 is made of transparent material, and both the upper and lower ends are equipped with sealing layers, which is intended to facilitate timely observation of the color of the pleural fluid. In addition, the outer ring of the support rod 10 is provided with multiple sets of connecting grooves, which are intended to fix the cannula 11 in a suitable position according to the needs.

[0055] In this embodiment, under normal conditions, the bottom of the moving component 21 can be fixed by the support rod 10. When movement is required, the rolling part of the moving component 21 can be rotated downwards to lift the device, thereby enabling movement. After the device is lifted, the locking part of the moving component 21 will insert into its rolling part for fixation, ensuring stability during movement. When the height needs to be adjusted, the driving part of the lifting component 22 can be rotated to move its lifting part up and down to adjust the height. At the same time, the rotating component 23 can be pushed to rotate, adjusting the overall orientation of the device. When the thoracic tube needs to be fixed, the clamping component 33 can be used to fix the thoracic tube, and the position of the clamping component 33 can be adjusted by rotating the positioning component 32 to control the fixed position of the tube. The clamping component 33 can also be rotated at will to adjust the orientation of the tube during fixation. If the path of the tube fixation needs to be adjusted, the bending component 31 can be bent at will to adjust the path of the tube fixation. During the use of the chest tube, the tube can be connected to the inlet and outlet of the cannula 11, allowing the effusion to flow through the cannula 11 for observation of its color and state. Simultaneously, the detection component 40 can monitor the fluid level within the chest tube and the patient's condition in real time. If any abnormalities occur in the fluid within the chest tube or in the patient's condition, the detection component 40 will promptly transmit the information, enabling medical personnel to understand the situation and take appropriate measures.

[0056] Secondly, please refer to again Figures 1-6 The movable component 21 includes a support leg 211 fixedly connected to the bottom of the support rod 10. A universal wheel 212 is rotatably connected to the bottom of the support leg 211. A limit block 213 is slidably connected to the bottom surface of the support leg 211. The bottom of the limit block 213 is movably inserted into the top of the universal wheel 212. A pull rod 214 is fixedly connected to the top of the limit block 213. The pull rod 214 is slidably connected to the top of the support leg 211. A first spring 215 is fixedly connected to both the front and rear sides of the top of the limit block 213. The top of the first spring 215 is fixedly connected to the top of the inner cavity of the support leg 211. A magnetic suction plate 216 is fixedly connected to the bottom surface of the support leg 211.

[0057] The lifting assembly 22 includes a lifting rod 221 slidably connected to the inner cavity of the support rod 10. A lead screw 222 is rotatably connected to the bottom of the inner cavity of the support rod 10. The top of the lead screw 222 is threadedly connected to the inner cavity of the lifting rod 221. A gear ring 223 is fixedly connected to the outer ring of the bottom of the lead screw 222. A gear rod 224 is rotatably connected to the middle of the support rod 10. The gear part of the gear rod 224 extends into the support rod 10 and meshes with the outer ring of the gear ring 223. A threaded groove is opened on the part of the gear rod 224 located outside the support rod 10, and a nut 225 is threadedly connected in the groove.

[0058] The rotating assembly 23 includes a shaft tube 231 fixedly connected to the top of the lifting rod 221. A rotating frame 232 is rotatably connected to the inner cavity of the shaft tube 231. A cylindrical rod 233 is slidably connected to the inner cavity of the shaft tube 231. A second spring 234 is fixedly connected to the middle of the cylindrical rod 233. The second spring 234 is fixedly connected to the inner cavity of the shaft tube 231. A groove is opened on the bottom outer ring of the rotating frame 232, and the cylindrical rod 233 is movably inserted into the groove.

[0059] The top of the caster wheel 212 is also provided with a magnetic plate 216, and the magnetic plate 216 on the caster wheel 212 is arranged opposite to the magnetic plate 216 on the support leg 211.

[0060] It should be noted that the limiting block 213 is positioned above the pivot of the universal wheel 212, so that the limiting block 213 cannot push the universal wheel 212 to rotate downwards in the normal state.

[0061] The outer ring of the nut 225 is provided with a handle, and the part of the nut 225 that contacts the surface of the support rod 10 is provided with an anti-slip layer, which is intended to improve the tightness of the nut 225 and ensure the stability of the gear rod 224.

[0062] In this embodiment, under normal conditions, the outrigger 211 is fixed to the ground and supported by the support rod 10. At this time, the caster wheel 212 is attracted to the bottom surface of the outrigger 211 by the magnetic plate 216. When the device needs to be moved, the caster wheel 212 can be rotated downwards and placed against the ground to lift the outrigger 211, thereby propelling the device forward. During the downward rotation of the caster wheel 212, the limiting block 213 moves downwards due to the thrust of the first spring 215, engaging the caster wheel 212 to ensure that it does not rotate accidentally during movement, thus maintaining the stability of the device. When the device needs height adjustment, rotating the gear rod 224 rotates the gear ring 223, which in turn rotates the lead screw 222, pushing the lifting rod 221 up and down to adjust the height of the device. Then, rotating the nut 225 contacts and fixes it to the surface of the support rod 10, ensuring the stable fixation of the gear rod 224. Meanwhile, the rotating frame 232 can rotate around the central tube 231 to adjust the overall orientation of the device. During the rotation, the cylindrical rod 233 will be continuously pushed out by the groove at the bottom of the rotating frame 232, and after the rotating frame 232 continues to rotate, it will be pushed back into the groove at the bottom of the rotating frame 232 by the second spring 234, forming a jerky tactile sensation and improving the positioning accuracy.

[0063] Secondly, please refer to again Figures 6-11 The bending assembly 31 includes a soft rubber strip 311 fixedly connected to the right side of the rotating frame 232, a corrugated pipe 312 fixedly connected to the top right side of the rotating frame 232, the corrugated pipe 312 fixedly connected to the top of the inner cavity of the soft rubber strip 311, and a cover plate 313 fixedly connected to the right end of the soft rubber strip 311.

[0064] The positioning component 32 includes a slider 321 slidably connected within a soft rubber strip 311. Friction plates 322 are slidably connected to both the front and rear sides of the inner cavity of the slider 321. A push rod 323 is slidably connected to the inner cavity of the slider 321. A trapezoidal block 324 is fixedly connected to one end of the push rod 323 located within the inner cavity of the slider 321. The inclined surface of the trapezoidal block 324 contacts the bottom of the friction plate 322. A third spring 325 is fixedly connected to the outer ring of the middle section of the push rod 323. The other end of the third spring 325 is fixedly connected to the middle of the inner cavity of the slider 321. A pressing plate 326 is fixedly connected to one end of the push rod 323 located outside the slider 321. An auxiliary rod 327 is fixedly connected to the rear side of the pressing plate 326. The auxiliary rod 327 is slidably connected to the inner cavity of the slider 321.

[0065] The clamping assembly 33 includes a turntable 331 rotatably connected to the bottom of the slider 321. The top outer ring of the turntable 331 is evenly provided with positioning grooves 332. The middle part of the slider 321 is threaded with a positioning bolt 333, which is in contact with the positioning groove 332. The bottom of the turntable 331 is rotatably connected with a clamping rod 334.

[0066] It should be noted that by opening the cover plate 313, the slider 321 can be removed from the soft rubber strip 311, or more sliders 321 can be added, thereby arbitrarily expanding the fulcrum for fixing the thoracic tube and improving its applicability.

[0067] The side of the friction plate 322 that contacts the soft rubber strip 311 is provided with an anti-slip strip to improve friction and ensure that the slider 321 can be fixed after the friction plate 322 contacts the soft rubber strip 311. The part of the friction plate 322 that contacts the inner cavity of the slider 321 is provided with a spring sheet (not shown in the figure) to ensure that the friction plate 322 will quickly return to its original position after it is released from the limit of the trapezoidal block 324, thus keeping the slider 321 fixed.

[0068] The clamping rod 334 consists of two sets of intersecting arc-shaped rods, and a torsion spring is provided at the top of the clamping rod 334. The purpose of the clamping rod 334 is to fix pipes of different sizes. At the same time, even if the pipe deforms during use, the clamping rod 334 will contract or open with the deformation of the pipe, thereby improving the stability of the pipe fixation.

[0069] The bottom of the positioning bolt 333 is equipped with an anti-slip pad, which is designed to improve the stability of the turntable 331.

[0070] In this embodiment, when adjusting the path of the tube fixation during the construction of the thoracic tube, the flexible rubber strip 311 can be bent into any shape. The corrugated pipe 312 provides sufficient flexibility and support to accommodate different bending angles. The bending shape of the flexible rubber strip 311 can be achieved by adjusting the position of the rotating frame 232, while opening the cover plate 313 facilitates the adjustment and maintenance of the flexible rubber strip 311. During tube fixation, the slider 321 can slide freely within the flexible rubber strip 311. By pressing the pressing plate 326, the push rod 323 pushes the trapezoidal block 324 inward, causing the friction plate 322 to disengage from the flexible rubber strip 311, thereby reducing friction and ensuring the slider 321 can slide. When it is necessary to fix the slider 321, simply release the pressing plate 326. The elastic force of the third spring 325 will pull the trapezoidal block 324 back, and the friction plate 322 will quickly reset, re-engaging with the flexible rubber strip 311, thus fixing the slider 321 in its original position. The turntable 331 can rotate freely to adjust the orientation of the tube during fixation. By rotating the positioning bolt 333 to contact the positioning groove 332, the turntable 331 can be fixed. At the same time, the thoracic tube can be placed between the two clamping rods 334 for clamping and fixation.

[0071] Secondly, please refer to again Figures 12-14The detection assembly 40 includes a display 41 fixedly connected to the top of the rotating frame 232. Multiple sets of wire clips 42 are fixedly connected to the rear side of the display 41. A data cable 43 is clipped into the wire clip 42. One end of the data cable 43 is electrically connected to the display 41, and the other end is electrically connected to a contact plate 44. Multiple sets of sensor heads 45 are fixedly connected to the bottom of the contact plate 44. A wire clip 46 is fixedly connected to the top of the contact plate 44. A spring wire 47 is electrically connected to the left side of the display 41. A pH detection head 48 is electrically connected to the bottom of the spring wire 47. The pH detection head 48 is fixedly connected to the inner cavity of the sleeve 11.

[0072] The sensor head 45 integrates a pressure sensor, a temperature sensor, and a humidity sensor. The pressure sensor is a surface-mount sensor, designed so that it can be attached to the surface in contact with the chest cavity.

[0073] It should be noted that silicone protrusions are provided on the front and rear sides of the contact plate 44, which are designed to improve the tactile sensation when the contact plate 44 contacts the patient's skin, and can also be fixed to the patient's skin by medical tape or other tools.

[0074] The wire clamp 46 is used to fix the port position of the thoracic tube to prevent the tube from shaking or shifting during use, which could affect the patient's wound.

[0075] In this embodiment, before using the thoracic tube, it is necessary to ensure that the inside of the tube and its connections are clean and leak-free. At this time, the contact plate 44 can be gently placed against the skin near the patient's chest cavity and secured with medical tape. The wire clamp 46 is used to hold the port of the thoracic tube, ensuring its stable position during testing and reducing errors caused by tube movement. Then, the display 41 is activated, and the pressure sensor built into the sensor head 45 monitors the pressure changes within the patient's chest cavity in real time via the signal transmitted through the data cable 43. Simultaneously, temperature and humidity sensors also work synchronously to collect temperature and humidity data of the environment surrounding the tube. This data is valuable for analyzing the tube's working status and predicting potential problems. Furthermore, the pH detection head 48, connected by the spring wire 47, extends into the inner cavity of the cannula 11 to directly detect the acidity and alkalinity of the body fluids within the thoracic cavity. pH value, as an important indicator of body fluid acid-base balance, plays an irreplaceable role in assessing the patient's physiological state and guiding treatment plans. The display 41 will display these detection data in real time, providing medical personnel with intuitive and accurate reference information.

[0076] During the testing process, medical staff can adjust the setup of the chest tubes or the patient's treatment plan in a timely manner based on changes in the data displayed on monitor 41. For example, if an abnormally high intrathoracic pressure is detected, it may be necessary to adjust the opening of the chest drainage tube or increase the drug dosage in a timely manner; if the pH deviates from the normal range, it is necessary to consider adjusting the infusion composition or taking other corrective measures.

[0077] The working principle of this invention is as follows: Under normal conditions, the outrigger 211 is fixed to the ground by supporting the support rod 10. When the device needs to be moved, the caster wheel 212 can be rotated downwards and placed on the ground to lift the outrigger 211, thereby pushing the device to move. At the same time, the limiting block 213 will be pushed downwards by the first spring 215 and locked into the caster wheel 212 to ensure the stability of the device's movement. When the height needs to be adjusted, the rotating gear rod 224 drives the gear ring 223 to rotate, which in turn causes the lead screw 222 to drive the lifting rod 221 to rise and fall, adjusting the height of the device. At the same time, the rotating frame 232 can rotate around the central tube 231, thereby adjusting the overall orientation of the device. During the construction of the thoracic cavity tube, when it is necessary to adjust the path of the tube fixation, the soft rubber strip 311 can be bent into any shape to change the path. During the tube fixation process, the slider 321 can slide freely within the soft rubber strip 311. By pressing the pressing plate 326, the push rod 323 will push the trapezoidal block 324 inward, causing the friction plate 322 to disengage from the soft rubber strip 311, thereby reducing friction and ensuring that the slider 321 can slide. Conversely, the friction plate 322 will contact the soft rubber strip 311, fixing the slider 321 in place. The turntable 331 can rotate freely to adjust the orientation of the tube during fixation. The chest tube can be placed between the two clamping rods 334 for clamping and fixation. Before use, the chest tube is connected to the inlet and outlet of the sleeve 11. At this time, the contact plate 44 can be placed on the skin near the patient's chest cavity. The wire clamp 46 is used to clamp the port of the chest tube, ensuring its stable position during testing. Subsequently, the pressure sensor built into the sensor head 45 will monitor the pressure changes within the patient's chest cavity in real time. Simultaneously, temperature and humidity sensors will also work synchronously to collect temperature and humidity data of the environment surrounding the tube. In addition, the pH testing head 48 connected to the spring wire 47 directly measures the acidity or alkalinity of the fluid in the pleural cavity. The display 41 will show these test data in real time, providing medical staff with intuitive and accurate reference information.
