Description

Technical Field

[0001] This invention belongs to the technical field of surgical auxiliary equipment, specifically a surgical guidewire interventional auxiliary device. Background Technology

[0002] In surgical procedures, guidewire intervention is a common technique used to guide surgical instruments to target sites or locate lesions. Current techniques rely heavily on manual operation by medical staff or simple stents. However, manual operation is susceptible to hand tremors, leading to insufficient guidewire positioning accuracy. Simple stents, on the other hand, have limited adjustment dimensions, cannot flexibly adapt to the needs of different surgical sites and angles, and lack stability, potentially shifting during surgery, affecting surgical outcomes and even posing safety risks. Therefore, there is an urgent need for a guidewire intervention auxiliary device that can achieve multi-dimensional precise adjustment and stable fixation to overcome the shortcomings of existing technologies. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a surgical guidewire interventional auxiliary device.

The lower end of the second pin is directly opposite the second through hole. The diameter of the second through hole is equal to the diameter of the second plug hole, and the diameter of the second pin is equal to the diameter of the second through hole.

[0009] Furthermore, the height adjustment assembly includes a mounting block, a first screw, a slide rod, and a rotating handle. There are two mounting blocks, both of which are fixedly mounted on the upper end of the movable block. The first screw is rotatably mounted inside one of the mounting blocks, and the slide rod is fixedly mounted inside the other mounting block. The rotating handle is fixedly mounted on the upper end of the first screw. One end of the guide wire tube is threadedly connected to the first screw, and the other end of the guide wire tube is slidably connected to the slide rod.

[0010] Furthermore, the threaded connection between the guide tube and the first screw satisfies the thread self-locking condition, that is, the thread helix angle α is less than or equal to the equivalent friction angle ρv of the thread pair, where α≤ρv.

[0014] The explanations of the nouns, conjunctions, or adjectives used in the above technical solutions are as follows: Fixed connection: refers to a connection in which parts or components are fixed in place and there is no relative movement. It is divided into two types: detachable connection and non-detachable connection.

[0015] (1) Detachable connection: The components are fixed together using screws, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connecting parts used must be correct (such as the length of the bolts, keys, wedges) and properly tightened.

[0016] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction, polishing, etc.) when making connections.

[0017] The beneficial effects of this invention are: 1. The overall height of the auxiliary interventional component can be adjusted by sliding the support plate along the support frame, the longitudinal adjustment can be achieved by sliding the moving block along the support plate, the overall lateral fine adjustment of the auxiliary interventional component can be achieved by the drive component, and the height adjustment component can adjust the height of the guidewire tube. This can accurately adapt to the guidewire interventional needs of different surgical sites and different patient body shapes, and solve the problem of limited adjustment dimensions of traditional stents.

[0018] 2. All adjustment parts adopt a double fixing design. The plug-in component achieves quick locking through spring-driven pins, and the threaded connection part meets the self-locking condition, ensuring that the components will not move on their own due to surgical vibration, external force touch, or other factors after adjustment. The guide wire tube provides a stable guiding channel for the guide wire, avoiding the shaking error of manual operation, greatly improving the guide wire positioning accuracy, and reducing surgical risks.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] A surgical guidewire interventional aid device, such as Figures 1-5As shown, it includes: a fixing component 1 and an auxiliary intervention component 2. The auxiliary intervention component 2 is installed on the side of the fixing component 1. The auxiliary intervention component 2 includes a support frame 3, a support plate 4, a moving block 5, a guide wire tube 6, and a height adjustment component 7 for adjusting the height of the guide wire tube 6. The support frame 3 has a circular structure, and a groove 8 is formed at the upper end of the support frame 3. The support plate 4 is disposed at the upper end of the support frame 3, and both ends of the support plate 4 are located within the groove 8. The support frame 3 has a plurality of first insertion holes 9 evenly distributed at the bottom of the groove 8. One of the support plates 4... A first plug-in assembly 10 for fixing the support plate 4 is fixedly installed at the end. A through groove 11 is opened in the middle of the support plate 4. The moving block 5 is slidably installed at the through groove 11 of the support plate 4. A plurality of second plug holes 12 are evenly distributed on both sides of the through groove 11 at the upper end of the support plate 4. A second plug-in assembly 13 for fixing the moving block 5 is fixedly installed on the moving block 5. The height adjustment assembly 7 is fixedly installed at the upper end of the moving block 5. The guide wire tube 6 passes through the moving block 5, and both ends of the guide wire tube 6 are connected to the height adjustment assembly 7.

[0024] The device consists of a fixed component 1 and an auxiliary intervention component 2. The auxiliary intervention component 2 is installed on the side of the fixed component 1, forming a dual-layer functional architecture of basic fixation and precise intervention. This ensures the overall stability of the device while focusing on the precise adjustment of the guidewire, solving the problem of traditional devices struggling to balance fixation and adjustment. A multi-dimensional adjustment system for planar position and height is initially constructed through the combination of a circular support frame 3, a sliding support plate 4, a movable moving block 5, and a height adjustment component 7. The support plate 4 slides along the groove 8 of the support frame 3, and the moving block 5 slides along the through groove 11 of the support plate 4 to adjust the planar position of the guidewire tube 6. The height adjustment component 7 adjusts the height of the guidewire tube 6 to adapt to the spatial position requirements of different surgical sites, breaking the limitations of traditional simple stents with single-dimensional adjustment. A first insertion component 10 is designed to fix the support plate 4, and a second insertion component 13 is designed to fix the moving block 5. Together with the height adjustment component 7, the guidewire tube 6 is fixed, achieving three-level fixation of the support plate 4, the moving block 5, and the guidewire tube 6. This prevents component displacement during surgery, improves guidewire positioning accuracy, and reduces surgical risks caused by component loosening. The support frame 3 adopts a circular structure, which fits the spatial layout around the operating table better and can flexibly avoid the surgical operation area. At the same time, the design of the grooves 8 embedded at both ends of the support plate 4 ensures the stability of the support plate 4 when sliding and avoids displacement, laying a structural foundation for subsequent precise adjustment.

[0025] In a preferred embodiment of the present invention, the bottom of the support frame 3 is provided with first sliding grooves 14 on both sides of the groove 8, and first sliders 15 are fixedly installed on both sides of the support plate 4. The first sliders 15 are adapted to the first sliding grooves 14 and are disposed within the first sliding grooves 14. By providing first sliding grooves 14 on both sides of the groove 8 of the support frame 3 and installing adapted first sliders 15 on both sides of the support plate 4, a sliding fit structure of sliding grooves and sliders is formed. Compared with the sliding method where the support plate 4 is simply placed directly in the groove 8, the lateral displacement of the support plate 4 can be limited, ensuring that the support plate 4 slides stably along the direction of the groove 8, avoiding jamming or displacement caused by uneven force during sliding, and improving the smoothness and positional accuracy of the adjustment process.

[0026] In a preferred embodiment of the present invention, the first plug-in assembly 10 includes a first connecting plate 16, a first connecting spring 17, and a first pin 18. A first through hole 19 is provided on one side of the support plate 4. The first plug-in assembly 10 is fixedly installed at the first through hole 19 of the support plate 4. The first connecting plate 16 is fixedly connected to the support plate 4 by two first connecting springs 17. The first pin 18 is fixedly installed at the lower end of the first connecting plate 16, with the lower end of the first pin 18 facing the first through hole 19. The diameter of the first through hole 19 is equal to the diameter of the first insertion hole 9, and the diameter of the first pin 18 is equal to the diameter of the first through hole 19. The first plug-in assembly 10 is composed of the first connecting plate 16, the first connecting spring 17, and the first pin 18. The pin is unlocked by pressing the first connecting plate 16 to compress the spring, and locked by releasing the connecting plate and restoring the spring. The operation is simple and intuitive, requiring no additional tools. Medical personnel can complete the fixing and unlocking actions with one hand, significantly reducing adjustment time.

[0027] In a preferred embodiment of the present invention, the support plate 4 has second sliding grooves 20 on both sides of the groove 8, and the moving block 5 has second sliders 21 fixedly installed on both sides. The second sliders 21 are adapted to the second sliding grooves 20 and are installed within the second sliding grooves 20. The second sliding grooves 20 on both sides of the through groove 11 of the support plate 4 and the adapted second sliders 21 installed on both sides of the moving block 5 maintain a stable sliding structure, limit the longitudinal offset of the moving block 5, ensure that the moving block 5 slides accurately along the through groove 11 of the support plate 4, and avoid tilting or offset caused by force when the moving block 5 slides, further refining the planar position adjustment accuracy of the guide tube 6. The cooperation of the second sliding grooves 20 and the second sliders 21 can disperse the pressure when the moving block 5 slides, reduce the direct friction between the moving block 5 and the through groove 11 of the support plate 4, reduce component wear, extend the service life of the moving block 5 and the support plate 4, and at the same time ensure the smoothness of the sliding process of the moving block 5, avoiding jamming that affects the adjustment efficiency.

[0028] In a preferred embodiment of the present invention, the second plug-in assembly 13 is fixedly installed on the upper end of the movable block 5. The second plug-in assembly 13 includes a second connecting plate 22, a second connecting spring 23, and a second pin 24. The second connecting plate 22 is fixedly connected to the movable block 5 by two second connecting springs 23. There are two second pins 24, and both second pins 24 are fixedly installed on the lower end of the second connecting plate 22. The upper end of the second slider 21 is provided with a second through hole 25. The lower end of the second pin 24 is directly opposite the second through hole 25. The diameter of the second through hole 25 is equal to the diameter of the second plug hole 12, and the diameter of the second pin 24 is equal to the diameter of the second through hole 25. The second insertion assembly 13 employs two second pins 24, corresponding to the second through holes 25 of the second sliders 21 on both sides of the moving block 5. Compared to single-pin fixation, it can be locked simultaneously from both sides of the moving block 5, distributing the fixing force and avoiding loosening or deformation caused by excessive force on a single pin, thus improving the stability of the moving block 5. This is especially suitable for fixing the moving block 5 when the guide wire 6 is under force during surgery. By pressing the second connecting plate 22 to compress the second connecting spring 23, the two pins are unlocked synchronously. After release, the springs synchronously reset and lock, making the operation convenient and highly synchronized, avoiding tilting of the moving block 5 caused by asynchronous unlocking / locking of a single pin. At the same time, the size matching of the second through hole 25 diameter = the second insertion hole 12 diameter = the diameter of the second pin 24 ensures that the pins fit tightly against the hole wall without gaps or loosening, further improving the fixing accuracy of the moving block 5.

[0029] In a preferred embodiment of the present invention, the height adjustment assembly 7 includes a mounting block 26, a first screw 27, a slide rod 28, and a rotating handle 29. There are two mounting blocks 26, both of which are fixedly mounted on the upper end of the movable block 5. The first screw 27 is rotatably mounted inside one of the mounting blocks 26, and the slide rod 28 is fixedly mounted inside the other mounting block 26. The rotating handle 29 is fixedly mounted on the upper end of the first screw 27. One end of the guide wire tube 6 is threadedly connected to the first screw 27, and the other end of the guide wire tube 6 is slidably connected to the slide rod 28. The height adjustment assembly 7 consists of two mounting blocks 26, a first screw 27, a slide rod 28, and a rotating handle 29. The first screw 27 is rotatably mounted on one mounting block 26, and the slide rod 28 is fixed to the other mounting block 26. One end of the guidewire tube 6 is threadedly connected to the screw, and the other end is slidably connected to the slide rod 28. Rotating the rotating handle 29 drives the screw to rotate, and the guidewire tube 6 moves up and down along the slide rod 28 through threaded transmission. Compared with manually pushing the guidewire tube 6 to adjust the height, threaded transmission can achieve micro-adjustment of the height, with higher precision, meeting the precise requirements for guidewire intervention height during surgery. The symmetrical layout of the screw and slide rod 28 ensures that the guidewire tube 6 is subjected to balanced forces at both ends when moving, preventing the guidewire tube 6 from tilting. At the same time, the sliding guide rod 28 restricts the rotational deviation of the guidewire tube 6, ensuring that the guidewire tube 6 always moves in the vertical direction, improving the stability and positional accuracy of height adjustment.

[0030] In a preferred embodiment of the present invention, the threaded connection between the guidewire tube 6 and the first screw 27 satisfies the thread self-locking condition, that is, the thread helix angle α is less than or equal to the equivalent friction angle ρv of the threaded pair, where α ≤ ρv. By ensuring that the threaded connection between the guidewire tube 6 and the first screw 27 satisfies the self-locking condition of thread helix angle α ≤ equivalent friction angle ρv of the threaded pair, automatic locking of the guidewire tube 6 after height adjustment can be achieved without the need for an additional locking mechanism. This prevents the guidewire tube 6 from sliding down or moving up on its own during surgery due to vibration, external force contact, or other factors, ensuring stable guidewire intervention height.

[0031] In a preferred embodiment of the present invention, the fixing component 1 includes a fixing block 30, a supporting vertical plate 31, a connecting rod 32, and a driving component 33. The supporting vertical plate 31 is fixedly installed on the upper end of the fixing block 30, the driving component 33 is installed inside the supporting vertical plate 31, the connecting rod 32 is installed on the side end of the driving component 33, and the auxiliary intervention component 2 is fixedly installed on the side end of the connecting rod 32. The fixing block 30 provides basic support, the supporting vertical plate 31 provides a mounting carrier for the driving component 33 and the connecting rod 32, and the connecting rod 32 connects the driving component 33 and the auxiliary intervention component 2, forming a complete fixing system of fixing, supporting, and transmitting, ensuring that the entire device can be stably fixed on the operating table, and at the same time providing a transmission path for the position adjustment of the auxiliary intervention component 2. By driving the connecting rod 32 to move up and down through the driving component 33, the height of the auxiliary intervention component 2 can be adjusted.

[0032] In a preferred embodiment of the present invention, the drive assembly 33 includes a drive motor 34 and a threaded rod 35. The threaded rod 35 is rotatably mounted inside the support vertical plate 31. The drive motor 34 is fixedly mounted on the upper end of the support vertical plate 31, and the output end of the drive motor 34 is fixedly connected to one end of the threaded rod 35. One end of the connecting rod 32 is threadedly connected to the threaded rod 35, and the threaded connection between the connecting rod 32 and the threaded rod 35 satisfies the thread self-locking condition, that is, the thread helix angle α is less than or equal to the equivalent friction angle ρv of the threaded pair, where α≤ρv. The drive assembly 33 employs a structure of drive motor 34 and threaded rod 35. Drive motor 34 rotates threaded rod 35, which in turn drives connecting rod 32 to move horizontally up and down via threaded transmission, achieving automated adjustment and reducing human error. The threaded connection between connecting rod 32 and threaded rod 35 meets self-locking requirements; once adjusted to the target horizontal position, no additional locking is needed. The threaded self-locking ensures stable fixation of connecting rod 32, preventing lateral displacement due to vibration or external force during surgery, thus improving the overall stability of the device. It also reduces operational steps and lowers the workload for medical personnel. Drive motor 34 provides stable power output, ensuring smooth movement of connecting rod 32 and preventing jamming or misalignment caused by uneven force during manual adjustment.

[0033] In a preferred embodiment of the present invention, the upper end of the fixing block 30 is provided with a threaded hole 36, and a long screw 37 is threadedly installed at the threaded hole 36. The upper end of the long screw 37 is provided with a rotating handle 38, and the lower end of the long screw 37 is fixedly installed with a rotating plate 39. The lower end of the rotating plate 39 is rotatably installed with a locking block 40. By opening a threaded hole 36 at the upper end of the fixing block 30 and installing the long screw 37, together with the rotating handle 38, the rotating plate 39 and the locking block 40, a fixed structure of threaded transmission and clamping is formed. By rotating the rotating handle 38, the long screw 37 is driven to move up and down, thereby pushing the locking block 40 to press against the fixing surface such as the operating table, which can be adapted to fixing surfaces of different thicknesses and materials.

[0034] Working principle and usage process of this invention: In use, the device is first fixed in a suitable position on the operating table by fixing component 1: rotate the handle 38 at the upper end of the long screw 37 to drive the long screw 37 to move down along the threaded hole 36 of the fixing block 30, and the rotating plate 39 at the lower end of the long screw 37 moves down accordingly, thereby pushing the locking block 40 to press against the surface of the operating table, completing the overall fixing of the device and preventing the device from shifting during the operation. Then, adjust the planar position of the auxiliary intervention component 2, press the first connecting plate 16 of the support plate 4, compress the first connecting spring 17, and move the first pin 18 upward with the first connecting plate 16, disengaging from the first insertion hole 9 at the bottom of the groove 8 of the support frame 3, thus releasing the support plate 4 from fixation; push the support plate 4 so that it slides along the first sliding groove 14 of the support frame 3 via the first sliders 15 on both sides, and after adjusting to a suitable lateral position, release the first connecting plate 16, the first connecting spring 17 resets, and drives the first pin 18 downward, passing through the first through hole 19 of the support plate 4 and inserting into the corresponding first insertion hole 9 of the support frame 3, thus re-fixing the support plate 4; then press the second connecting plate 22 of the moving block 5, compress the second connecting spring 23, and move the second pin 24 upward to disengage from the second insertion hole 12 of the support plate 4, thus releasing the moving block 5 from fixation. The movable block 5 is fixed; the movable block 5 is pushed so that it slides along the second slide groove 20 of the support plate 4 through the second sliders 21 on both sides. After adjusting to a suitable longitudinal position, the second connecting plate 22 is released, the second connecting spring 23 is reset, and the second pin 24 is driven to move down, pass through the second through hole 25 of the second slider 21 and insert into the corresponding second insertion hole 12 of the support plate 4 to fix the movable block 5; finally, the drive motor 34 on the support vertical plate 31 is started, and the output end of the drive motor 34 drives the threaded rod 35 to rotate. The connecting rod 32, which is threaded to the threaded rod 35, moves laterally along the threaded rod 35, thereby driving the auxiliary intervention component 2 to be adjusted to the height required for the operation. The drive motor 34 is turned off. Due to the thread self-locking characteristics of the connecting rod 32 and the threaded rod 35, the auxiliary intervention component 2 is stably maintained in the target position. Finally, the height of the guidewire tube 6 is finely adjusted: Rotating the handle 29 of the height adjustment component 7 causes the first screw 27 to rotate around the mounting block 26. The guidewire tube 6, threadedly connected to the first screw 27, slides up and down along the slide rod 28 under the force of the thread. After adjusting to the required height for guidewire intervention, stop rotating the handle 29. Due to the self-locking characteristic of the thread between the guidewire tube 6 and the first screw 27, the guidewire tube 6 is stably fixed at the target height. Pass the surgical guidewire through the guidewire tube 6, and the precise guidewire interventional surgical procedure can begin.
