Description

Technical Field

[0001] The present invention relates to the field of ultrasound guidance technology, in particular to an ultrasound intervention device for assisting puncture biopsy. Background Art

[0002] Ultrasonic interventional devices are a branch of modern ultrasound medicine. They are developed on the basis of ultrasound imaging and are used to meet the needs of clinical diagnosis and treatment. This device allows doctors to complete various puncture biopsies, X-ray angiography, aspiration, intubation, injection and other operations under real-time ultrasound monitoring or guidance. Ultrasonic interventional devices mainly include components such as ultrasound probes, puncture needles and puncture stents.

[0003] Existing puncture stents are generally made of stainless steel or plastic. When in use, the knob needs to be opened and the stent as a whole needs to be put on the ultrasound probe. However, it is necessary to ensure that the puncture guide point on the stent is aligned with the axis of the ultrasound probe to reduce the error of puncture. Therefore, it is necessary to ensure that the stent and the ultrasound probe fit perfectly. This results in each stent only matching one size of ultrasound probe, which has poor matching and is not conducive to the promotion of puncture stents.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Embodiment 1

[0040] See also Figure 1-6 The present invention provides a technical solution: an ultrasonic intervention device for assisting puncture biopsy, comprising an ultrasonic probe 1, wherein an outer surface of one side of the ultrasonic probe 1 is provided with a puncture frame 5 for puncture guidance;

[0043] See also Figure 1-2, a transverse bracket 2, the two sides of the transverse bracket 2 are respectively fixedly connected to the two groups of longitudinal brackets 3, the overall length of the transverse bracket 2 and the longitudinal bracket 3 is adjustable, which is convenient for matching with ultrasound probes 1 of different sizes, the transverse bracket 2 includes a connecting plate 20, an adjusting cavity 21 is opened inside the connecting plate 20, and a rotating gear 22 is connected to the middle position of the adjusting cavity 21 through a rotating shaft, and a coil spring 24 is fixedly connected to the outer surface of the transmission gear 22, and two groups of tooth plates 23 are meshed on the annular outer surface of the rotating gear 22, and the two groups of tooth plates 2 3 are respectively located at the upper and lower sides of the rotating gear 22, and the tooth plate 23 is fixedly connected to the longitudinal bracket 3 on the side away from the rotating gear 22, and the rotating gear 22 is provided with a rotational torque by the coil spring 24. When the tooth plate 23 on one side is squeezed and changes its length, it will synchronously drive the other set of tooth plates 23 to move, and the movement amount of the two sets of tooth plates 23 is consistent, so that the puncture frame 5 is always aligned with the axis of the ultrasonic probe 1, so that the entire puncture bracket can be adapted to more ultrasonic probes 1, thereby improving the versatility of the puncture bracket. The known ultrasonic probes 1 are all symmetrically designed;

[0044] See also Figure 6 , a longitudinal bracket 3, wherein the longitudinal bracket 3 includes a connecting block 30, one end of the connecting block 30 is fixedly connected to one of the two groups of transverse brackets 2, and the other end of the connecting block 30 is provided with a connecting block 2 31, and the end of the connecting block 2 31 away from the connecting block 30 is fixedly connected to the other group of transverse brackets 2, and the connecting block 1 30 and the connecting block 2 31 are both fixedly connected to the tooth plate 23, and an adjusting groove 32 is provided on the outer surface of the connecting block 2 31, and an adjusting block 34 is slidably connected inside the adjusting groove 32, and a spring 33 is fixedly connected between the two, and the adjusting block 34 is fixedly connected to the connecting block 30, and the adjusting block 34 slides inside the adjusting groove 32, and the spring 1 33 provides traction, so that the longitudinal bracket 3 can clamp and fix the ultrasonic probes 1 of different thicknesses, which is used to match the transverse bracket 2, increase the clamping force of the puncture bracket as a whole on the ultrasonic probe 1, and increase stability.

[0045] See also Figure 4-5A circular hole 29 is provided on the outer surface of one group of the connecting plates 20, and a telescopic block 27 is rotatably connected to the inner surface of the circular hole 29 through a bearing shaft, and the telescopic block 27 is aligned with the rotating gear 22. The end of the coil spring 24 away from the rotating gear 22 is fixedly connected to the telescopic block 27, and the end of the telescopic block 27 away from the coil spring 24 is provided with a knob 25, and a telescopic groove 26 is provided on the outer surface of the knob 25, and the telescopic block 27 is located inside the telescopic groove 26. One end of the knob 25 is fixedly connected to a plug plate 251, and a slot 28 is provided at the corresponding position of the connecting plate 20 and the plug plate 251, which is connected to the rotating gear 22 through the coil spring 24, so as to achieve the effect that the two groups of tooth plates 23 can automatically retract. At the same time, a rotatable telescopic block 27 is provided on one side of the coil spring 24, the purpose of which is to increase the elastic force generated by the coil spring 24 within the elastic limit of the coil spring 24 by rotating the coil spring 24, thereby increasing the lateral clamping force of the tooth plate 23 pulling the longitudinal bracket 3 to the ultrasonic probe 1, and preventing the puncture bracket from being offset as a whole during use. The number of the slots 28 is several groups, and they are distributed in a circular array around the circular hole 29. The knob 25 is made of magnetic material, and the connecting plate 20 and the knob 25 are magnetically adsorbed. The annular outer surface of the telescopic block 27 is fixedly connected to the limiting block 271, and the limiting slot 261 is provided at the corresponding position of the telescopic slot 26 and the limiting block 271, and the limiting block 271 is located inside the limiting slot 261;

[0046] See also Figure 5 When in use, the user toggles the knob 25 along the axial direction of the knob 25, so that the knob 25 gradually moves away from the connecting plate 20 along the telescopic slot 26 under the guidance of the limit slot 261 and the limit block 271, and the plug plate 251 moves synchronously with the knob 25 and disengages from the slot 28, so that the knob 25 and the telescopic block 27 are in a rotatable state. Then the user rotates the knob 25 as needed to change the deformation of the coil spring 24, thereby achieving the purpose of changing the elastic force of the coil spring 24. After the adjustment is completed, the user directly releases the knob 25. The knob 25 will move back toward the connecting plate 20 under the action of the magnetic force until the plug plate 251 is inserted into the slot 28 to complete the restriction of the telescopic block 27. The above technical solution can clamp and fix ultrasound probes 1 of different sizes, thereby improving the universal efficiency of the puncture bracket.

[0047] Embodiment 2

[0048] See also Figure 7-14 , this embodiment is further extended on the basis of the first embodiment;

[0049] One end of the transverse bracket 2 is fixedly connected to the longitudinal bracket 3, and the number is a group, and the overall distribution is L-shaped. A connecting frame 1 4 designed for an L-shaped structure is provided opposite to the transverse bracket 2. The other end of the transverse bracket 2 is fixedly connected to a connecting frame 2 6, and the connecting frame 2 6 is connected to the connecting frame 1 4. The upper and lower ends of the connecting frame 1 4 are provided with L-shaped sliding grooves 47, and the puncture frame 5 is slidably connected to the sliding groove 47;

[0050] Since ultrasound guidance has short-axis guidance and long-axis guidance, specifically out-of-plane puncture method and in-plane puncture method, the puncture bracket can be fixed on the ultrasound probe 1 of different sizes, so that the puncture bracket 5 can slide along the slide groove 47, so that when the user uses the puncture bracket, the long-axis guidance and short-axis guidance can be directly switched according to the scanning image of the ultrasound probe, and there is no need to replace the puncture bracket, thereby improving the puncture efficiency.

[0051] See also Figure 9-10 The connecting frame 14 is provided with a second sliding groove 46 inside, and a second sliding rod 44 is slidably connected inside the second sliding groove 46. The connecting frame 14 is also provided with a first sliding groove 41 inside, and a first sliding rod 43 is slidably connected inside the first sliding groove 41. The outer surfaces of the first sliding rod 43 and the second sliding rod 44 are provided with teeth. The first sliding groove 41 and the second sliding groove 46 are rotatably connected with a reduction gear 42. The second sliding groove 46 and the first sliding groove 41 are provided with circular grooves of the same size as the reduction gear 42. The reduction gear The wheel 42 is composed of a small gear and a large gear. The small gear meshes with a sliding rod 1 43, and the large gear meshes with a sliding rod 2 44. The contact direction of the two is on the same side of the reduction gear 42. The circumference of the small gear is half of the large gear. The end of the sliding rod 2 44 away from the reduction gear 42 is fixedly connected to the longitudinal bracket 3. The end of the sliding rod 1 43 is fixedly connected with a magnetic body 1 45. The magnetic body 1 45 is magnetically adsorbed to the puncture frame 5. A part of the sliding groove 1 41 is designed to be open, which is convenient for the magnetic body 1 45 to slide.

[0052] In this embodiment, the puncture frame 5 is connected to the outer surface of the connecting frame 1 4 and is aligned with the midpoint of the connecting plate 20, and further aligned with the axis of the ultrasonic probe 1. When the fixed ultrasonic probe 1 is reduced in size, the coil spring 24 drives the two sets of tooth plates 23 to shrink through elastic force. Since the length of the connecting frame 1 4 is not adjustable, the connecting plate 20 and the longitudinal bracket 3 move relative to the connecting frame 1 4 toward the connecting frame 2 6, and the moving speed of the longitudinal bracket 3 is twice that of the connecting plate 20. In order to keep the puncture frame 5 always aligned with the connecting plate 2 0, it is necessary to ensure that the puncture frame 5 also moves toward the connecting frame 26 at the same speed as the connecting plate 20. When the longitudinal bracket 3 drives the sliding rod 244 to move inside the sliding groove 246, the reduction gear 42 rotates. The sliding speed of the sliding rod 1 43 is reduced by the design of the large gear and the small gear, and its speed is half of the speed of the sliding rod 1 44, so that the magnetic body 1 45 fixedly connected to the sliding rod 1 43 pushes the puncture frame 5 to move, thereby ensuring that the puncture frame 5 is aligned with the axis of the ultrasonic probe 1.

[0053] See also Fig.14 The puncture frame 5 includes a carrier 50, and a slider 53 is connected to the position of the carrier 50 corresponding to the slide groove 47. The slider 53 is embedded in the slide groove 47. The slider 53 is in three groups to increase the stability of the carrier 50. A guide frame 51 is fixedly connected to the side of the carrier 50 away from the slider 53. The angle of the guide frame 51 can be adjusted, and the puncture needle is guided by the guide frame 51 for puncture.

[0054] See also Fig.14 The carrier 50 is slidably connected with the slider 53, and a socket 54 is provided at one end of the slider 53 close to the carrier 50, and a spring 55 is fixedly connected to the inner wall of the socket 54. A plug rod 52 matching the socket 54 is fixedly connected to the corresponding positions of the carrier 50 and the socket 54. The carrier 50 is slidably connected with the slider 53 in a telescopic manner through the plug rod 52, the socket 54, and the slider 53, so that a certain margin can be generated between the carrier 50 and the slider 53, thereby making it easy for the carrier 50 to slide at the corner of the connecting frame 14.

[0055] See also Fig.13 , the connection frame 1 4 and the connection frame 2 6 have an accommodating chamber 61 with an overall C-shaped structure design at a position corresponding to the connection frame 1 4 , the accommodating chamber 61 is slidably connected to a push rod 64 near the upper end area, and the end of the push rod 64 is fixedly connected to the connection frame 2 6 , and the accommodating chamber 61 has a driving groove 66 near the lower end area, and a driving plate 62 is slidably connected inside the driving groove 66, and a spring 3 63 is fixedly connected between the driving plate 62 and the driving groove 66, and the driving plate 62 is designed in an L-shaped structure, and a magnetic body 2 65 is fixedly connected to the end thereof away from the spring 3 63, and the magnetic body 2 65 is magnetically connected to the carrier 50, and the magnetic body corresponds to the carrier 50;

[0056] When the puncture frame 5 moves to the short axis area of ​​the ultrasonic probe 1 through the slide slot 47, it is still necessary to keep the puncture frame 5 aligned with the short axis axis of the ultrasonic probe 1. Since the connecting frame 1 4 is in an immovable state, when the distance of the longitudinal bracket 3 is shortened, with the connecting frame 1 4 as a reference, the connecting block 1 30 moves toward the connecting block 2 31 under the action of the spring 1 33 pulling the adjusting block 34. Similarly, the connecting frame 2 6 also moves toward the connecting frame 1 4. At this time, the push rod 64 slides inside the accommodating chamber 61 to compress the space inside the accommodating chamber 61. The driving plate 62 is designed as an L-shaped structure. The shorter part of the driving plate 62 is away from the spring 3 63. One side has an area twice that of the push plate, and liquid is injected into the accommodating chamber 61. The push plate and the driving plate 62 are sealed from the accommodating chamber 61. When the connecting frame 2 6 moves toward the connecting frame 1 4, the driving plate 62 is driven by the push plate to squeeze the liquid and drives the magnetic body 2 65 to move toward the connecting frame 1 4, thereby pushing the carrier 50 magnetically connected to the magnetic body 2 65 to move toward the axis of the ultrasonic probe 1. Through the above technical structure, the puncture frame 5 is restricted by the magnetic body 1 45 and the magnetic body 2 65 on the long axis side of the connecting frame 1 4 and the short axis side of the connecting frame 1 4, respectively, and is aligned with the axis of the ultrasonic probe 1.
