Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a universal ultrasound interventional guidance device for convex array and linear array ultrasound probes. Background Technology

[0002] In the current era of rapid development in clinical ultrasound-guided interventional diagnosis and treatment, abdominal convex array probes and high-frequency linear array probes are key tools. The guide frame, in conjunction with the ultrasound probe, can precisely guide the puncture needle to the target location under the guidance of real-time ultrasound images.

[0003] However, the guide frames used with ultrasound probes face a low adoption rate, primarily due to their poor compatibility. They cannot widely accommodate different types of ultrasound probes, significantly limiting their flexible clinical application. Their stability is also somewhat lacking; the needle fixation structures on existing guide frames often use a single, relatively large aperture, making the needle prone to shifting or vibrating, affecting puncture accuracy. Furthermore, the fixed angle of the needle on existing guide frames makes it difficult to adapt to special situations. Due to these shortcomings, clinicians often rely on manual guidance, which not only increases learning time but also raises the difficulty of guidance, reducing the efficiency and accuracy of ultrasound interventional procedures. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a universal ultrasound interventional guidance device for convex array and linear array ultrasound probes, which solves the problems of poor adaptability, insufficient stability and limited puncture angle of the existing guide frame.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a universal ultrasound interventional guidance device for convex array and linear array ultrasound probes, including an elastic band and a banding mechanism for tightening the elastic band, and a guiding mechanism for guiding and adjusting the puncture angle of the puncture needle.

[0006] The guiding mechanism includes a mounting block connected to the elastic band, a guide block slidably connected to the mounting block, and an adjusting rod threadedly connected to the mounting block along the sliding direction of the guide block, the end of the adjusting rod being rotatably connected to the guide block;

[0007] The guide block is rotatably connected to a first perforated ball, and the mounting block is rotatably connected to a second perforated ball. The puncture needle can pass through the through holes on the first and second perforated balls, and the inner wall of the through hole is provided with an elastic pad that can cover the outer periphery of the puncture needle.

[0008] Optionally, the gathering mechanism includes a gathering box with a built-in cavity, and the gathering box is provided with a gathering port communicating with the cavity;

[0009] The cavity contains two gathering shafts that are rotatably connected to the gathering box, and the two ends of the elastic gathering band can pass through the gathering opening and be connected to the two gathering shafts respectively.

[0010] The gathering box is provided with a first gathering knob that can engage with the two gathering shafts from the outside to the inside. When the end of the first gathering knob is placed outside the gathering box and is attached to the surface of the gathering box, the first bevel tooth on the first gathering knob can engage with the second bevel tooth on the surface of the gathering box.

[0011] Optionally, two parallel racks are movably threaded through the spool box, and one end of each rack is connected to a clamp that can be placed in the cavity. A second spool knob that can mesh with the two racks is movably threaded through the spool box from the outside to the inside. When the end of the second spool knob is placed outside the spool box and is attached to the surface of the spool box, the third bevel tooth on the second spool knob can engage with the fourth bevel tooth on the surface of the spool box.

[0012] Furthermore, when the second gathering knob is rotated, the two clamps can move synchronously toward the elastic gathering bands respectively connected to the two gathering shafts.

[0013] Optionally, a section of the rack connected to the clamp is C-shaped, and this section of the rack is located outside the gathering box.

[0014] Optionally, the elastic band is flat.

[0015] Optionally, the elastic band and the gathering box can be arranged to form a closed loop structure, and the inner surface of the elastic band is provided with a plurality of silicone pillars.

[0016] Optionally, the gathering box includes a gathering base box and a cover detachably connected to the gathering base box, and the two ends of the gathering shaft are respectively rotatably connected to the cover and the gathering base box, and the first gathering knob is movably inserted through the cover.

[0017] Optionally, the end of the adjusting rod located outside the mounting block is provided with a knob, and the surface of the knob is provided with anti-slip texture.

[0018] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: Through the combined design of the convergence mechanism and the elastic convergence band, different models and sizes of ultrasound probes can be adapted by adjusting the length of the elastic convergence band extending beyond the convergence plate. Simultaneously, the position of the guide block can be precisely adjusted by rotating the adjusting rod, and with the use of the first and second perforated ball bearings, the tilt angle of the puncture needle can be flexibly adjusted, solving the problem of limited puncture angle. Furthermore, the elastic pads provided on the first and second perforated ball bearings ensure the stability of the puncture needle position while adapting to the needs of puncture needles with different orifice diameters, effectively increasing the flexibility and versatility of the guiding device.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the invention and therefore only show the components relevant to the invention.

[0028] It should be noted that if directional indicators (such as up, down, bottom, top, etc.) are involved in this embodiment, these directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature. Unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0029] like Figures 1-6As shown, a universal ultrasound interventional guidance device for convex array and linear array ultrasound probes includes an elastic band 1, a tightening mechanism for tightening the elastic band 1, and a guiding mechanism for guiding and adjusting the puncture angle of the puncture needle 2. The guiding mechanism is connected to the elastic band 1, which is made of a flexible material and has a certain degree of elasticity. Therefore, within the original length and extended length range of the elastic band 1, it can be operated to wrap around probes of different specifications, and when the tightening mechanism is used to tighten the elastic band 1, the guiding mechanism can be stably fixed to the probe. Further, the guiding mechanism includes a mounting block 3 connected to the elastic band 1, a guiding block 4 slidably connected to the mounting block 3, and an adjusting rod 5 threadedly connected to the mounting block 3 along the sliding direction of the guiding block 4. The end of the adjusting rod 5 is rotatably connected to the guiding block 4. The mounting block 3 is fixedly connected to the elastic band 1, and when the adjusting rod 5 is twisted, the guiding block 4 can move along a fixed path and direction under the traction of the adjusting rod 5. Furthermore, a first perforated ball bearing 401 is rotatably connected to the guide block 4, and a second perforated ball bearing 301 is rotatably connected to the mounting block 3. The puncture needle 2 can pass through the through holes on the first perforated ball bearing 401 and the second perforated ball bearing 301, and the inner wall of the through hole is provided with an elastic pad that can cover the outer periphery of the puncture needle 2. The second perforated ball bearing 301 is rotatably connected to a fixed position on the mounting block 3. When the operator operates the puncture needle 2 to pass through the first perforated ball bearing 401 and the second perforated ball bearing 301, the tip of the puncture needle 2 can be exposed outside the mounting block 3. When the operator continues to operate the puncture needle 2 to pass through the second perforated ball bearing 301, the puncture needle 2 can be inserted into the human body. It is important to note that because the second perforated ball 301 is rotatably connected to a fixed position on the guide block 4, and when the operator twists the adjusting rod 5 to drive the guide block 4 to slide, the puncture needle 2 rotates around the second perforated ball 301 as its axis of rotation, thereby flexibly adjusting the puncture angle of the puncture needle 2. The elastic pads provided on the first and second puncture balls increase the friction between the puncture needle 2 and the inner wall of the through hole when the puncture needle 2 enters through it, ensuring the stability of the puncture needle 2's position. Simultaneously, because the elastic pads possess good elasticity and deformation recovery capability, within the range of the elastic pads' deformation recovery capability, the guiding mechanism can accommodate different types of puncture needles 2, thereby effectively increasing the versatility of the guiding device.

[0030] Furthermore, such as Figure 2 , Figure 3As shown, the displacement of the guide block 4 and the rotation of the first perforated ball 401 and the second perforated ball 301 allow the puncture needle 2 to be angled within a fixed operating plane. Furthermore, when the guide mechanism is fixed to the probe via the elastic band 1 and the retraction mechanism, the operating plane of the puncture needle 2 is fixed relative to the probe. During actual operation, the operator can adjust the position of the probe to change the position of the operating plane of the puncture needle 2, thereby changing the initial puncture angle of the puncture needle 2. Combined with the ability of the puncture needle 2 to further adjust the puncture angle within the operating plane, the guide device in this technical solution can adapt to the operator's needs for using the puncture needle 2 in special circumstances.

[0031] Furthermore, in this technical solution, the guide block 4 can be slidably connected to the limiting groove provided on the mounting block 3. The sliding fit between the limiting groove and the guide block 4 can adopt the existing fit structure such as dovetail groove and dovetail block, T-shaped block and T-shaped groove, or rectangular block and rectangular groove. Preferably, in this technical solution, the guide block 4 is rectangular, and one end of the adjusting rod 5 can extend into the rectangular groove (limiting groove) and be rotatably connected to the guide block 4, thereby restricting the range of motion of the guide block 4 within the rectangular groove (limiting groove), and the guide block 4 can move along the corresponding rectangular groove (limiting groove) under the traction of the adjusting rod 5. It should be noted that in this technical solution, the end of the adjusting rod 5 located outside the mounting block 3 is provided with a knob part 501, and the surface of the knob part 501 is provided with anti-slip texture to facilitate the operator to manually rotate the adjusting rod 5.

[0032] The above, such as Figure 2 , Figure 4As shown, the gathering mechanism includes a gathering box 6 with a built-in cavity, and a gathering opening 601 communicating with the cavity. Two gathering shafts 7 are respectively rotatably connected to the gathering box 6 within the cavity. The two ends of the elastic gathering band 1 can pass through the gathering opening 601 and are respectively connected to the two gathering shafts 7. A first gathering knob 8, capable of engaging with the two gathering shafts 7, is movably inserted from the outside to the inside of the gathering box 6. Specifically, the rotation axes of the two gathering shafts 7 and the first gathering knob 8 are parallel to each other. Both the two gathering shafts 7 and the first gathering knob 8 are provided with teeth, and the teeth on the first gathering knob 8 engage with the teeth on the two gathering shafts 7. It should be noted that the tooth grooves on the teeth are straight teeth, that is, the tooth grooves are linearly distributed along the axial direction of the gathering shafts 7 and the first gathering knob 8, allowing the first gathering knob 8 to move up and down along its axis. Furthermore, when the end of the first gathering knob 8 outside the gathering box 6 is attached to the surface of the gathering box 6, the first bevel tooth 801 on the first gathering knob 8 can engage with the second bevel tooth 602 on the surface of the gathering box 6. It should be noted that, since the elastic gathering band 1 has a certain elasticity, when the elastic gathering band 1 is tightened by twisting the first gathering knob 8, the elastic gathering band 1 will exert a certain tension on the gathering shaft 7 due to its extension. This tension can drive the first gathering knob 8 to rotate. Therefore, when the first gathering knob 8 is pressed down to be attached to the gathering box 6, the first bevel tooth 801 on it can engage with the second bevel tooth 602 on the gathering box 6, thereby effectively locking the tightened elastic gathering band 1, so that the gathering band can be stably looped around the probe.

[0033] Furthermore, in this embodiment, as Figure 1 , Figure 4As shown, two parallel racks 9 are movably threaded through the collection box 6. One end of each rack 9 is connected to a clamping plate 10 that can be placed in the cavity. A second collection knob 11, which can mesh with the two racks 9, is movably threaded through the collection box 6 from the outside to the inside. When the end of the second collection knob 11 outside the collection box 6 is attached to the surface of the collection box 6, the third bevel tooth 1101 on the second collection knob 11 can engage with the fourth bevel tooth 603 on the surface of the collection box 6. Specifically, when the second collection knob 11 is manually rotated, the two clamping plates 10 can move synchronously toward (or away from) the elastic collection bands 1 connected to the two collection shafts 7 respectively. When the two clamping plates 10 move toward the elastic collection bands 1, they can further contract the elastic collection bands 1 wrapped around the probe, ensuring the elastic collection bands 1 are firmly wrapped around the probe and improving the stability of the puncture needle 2 operation. At the same time, when the two clamping plates 10 on the rack 9 move towards each other and retract the elastic band 1 inward, the elastic band 1 will drive the two clamping plates 10 to move in opposite directions due to its own elasticity. Therefore, after the second retraction knob 11 is pressed down until the third bevel tooth surface and the fourth bevel tooth surface are engaged, the positions of the two clamping plates 10 can be effectively locked.

[0034] As described above, the section of the rack 9 connected to the clamping plate 10 is C-shaped, and this section of the rack 9 is placed outside the tucking box 6, so that the operator can directly press the rack 9 into the tucking box 6 to further tighten the elastic tucking band 1, which is convenient for operation.

[0035] Furthermore, such as Figure 1 As shown, in this technical solution, the elastic band 1 is flat to increase the contact area between the elastic band 1 and the probe surface, thus dispersing the pressure range exerted by the elastic band 1 on the probe. Simultaneously, the elastic band 1 and the band box 6 can form a closed-loop structure, and several silicone pillars 101 are provided on the inner surface of the elastic band 1 to increase the friction between the elastic band 1 and the probe surface, preventing relative sliding between the elastic band 1 and the probe after tightening.

[0036] Furthermore, such as Figure 2 As shown, the slugging box 6 includes a slugging base box 61 and a cover 62 detachably connected to the slugging base box 61. The two ends of the slugging shaft 7 are rotatably connected to the cover 62 and the slugging base box 61, respectively. A first slugging knob 8 is movably inserted through the cover 62. That is, the slugging base box 61 and the cover 62 can be connected by bolts, latches, snaps, or other structures (not shown in the figure) to facilitate the assembly and disassembly of the components, and to facilitate daily maintenance and disinfection.

[0037] Working principle: The front end of the ultrasound probe is placed within the closed-loop structure formed between the elastic band 1 and the collection box 6. The length of the elastic band 1 is then adjusted by rotating the first tightening knob 8, thus adjusting the loop size of the closed-loop structure, ensuring that the side of the elastic band 1 with the silicone pillar 101 fits tightly against the front end surface of the probe. The first tightening knob 8 is then pressed down until its first conical tooth 801 engages with the second conical tooth 602 on the collection box 6, effectively locking the tightened elastic band 1. The second tightening knob 11 is then rotated, or the section of the rack 9 outside the collection box 6 is pressed down, further tightening the elastic band 1 around the probe to ensure stable probe fixation. The puncture needle 2 is then passed through the first perforated ball 401 on the guide block 4 and the second perforated ball 301 on the mounting block 3, allowing the operator to adjust the tilt angle of the puncture needle 2 by rotating the adjusting rod 5 to drive the guide block 4 to move. Finally, the operator can perform the puncture procedure safely and accurately under the real-time guidance of the ultrasound probe.

[0038] Based on the preferred embodiments of the present invention described above, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
