Description

Technical Field

[0001] The present invention relates to the technical field of medical puncture, and in particular to a puncture device based on ultrasound guidance. Background Art

[0002] Ultrasound-guided puncture is a technology developed on the basis of ultrasound imaging to meet the needs of clinical diagnosis and treatment. During ultrasound-guided puncture, ultrasound needs to be emitted to the corresponding part of the patient through a probe, and then the puncture needle can be used to easily extract the diseased tissue in the patient's body or inject drugs into a target part of the patient's body. Therefore, it has made great contributions to doctors' accurate understanding of the patient's condition, formulation of medical plans, and auxiliary treatment. In the existing patent with patent number CN116549072B, an ultrasound-guided puncture device is disclosed.

[0003] However, in actual operation, when the user needs to change the out-of-plane guidance to the in-plane guidance of the ultrasound-guided puncture device in the above patent, the angle of the probe needs to be changed greatly. However, at this time, the puncture needle has been inserted into the patient's skin. Therefore, when the user changes the position of the probe, it is easy to cause the problem of unstable holding and falling when the finger changes its position on the outer wall of the probe, and there is a risk of the probe falling and being damaged. If the finger holding position is not changed, it is necessary to change the palm angle or the user's sitting posture, etc., which affects the stability of holding the ultrasound probe; at the same time, the puncture angle and puncture depth that can be provided by the traditional puncture assembly are usually fixed, while the puncture angle and puncture depth required for different affected parts of the patient are different. Therefore, when performing multiple sets of interleaving, it is necessary to prepare puncture assemblies of various specifications, which is more troublesome in terms of operation steps; in addition, in the actual puncture process, once the patient's limbs move under the influence of themselves or the external environment, it is easy to cause some slight deviations in the puncture process, thereby affecting the puncture accuracy, and then affecting the subsequent treatment effect. In view of the above problems, the present invention document proposes a puncture device based on ultrasound guidance. Summary of the invention

As the second lead screw 706 rotates, the moving block 707 is driven to continuously move up and down inside the placement frame 702, thereby driving the mounting sleeve 708 and the puncture needle 704 to move together.配合安置框702上设置的刻度盘710,方便令穿插针704伸出安置框702合适的长度,之后,在实际使用穿刺针704进行穿刺操作时,通过转向球709,方便对穿刺针704的角度进行实时调节,从而能够随时对穿刺角度和穿刺深度进行合适的调节,以满足病人不同患处的需求,在进行多组穿插时,无需准备多种规格的穿刺组件,使得操作步骤上更加简便。With the scale 710 provided on the placement frame 702, it is convenient to make the insertion needle 704 extend from the placement frame 702 by an appropriate length. After that, when actually using the puncture needle 704 for puncture operation, through the steering ball 709, it is convenient to adjust the angle of the puncture needle 704 in real time, so that the puncture angle and puncture depth can be adjusted appropriately at any time to meet the needs of different affected parts of the patient. When performing multiple groups of insertions, there is no need to prepare puncture components of various specifications, making the operation steps more convenient.

[0051] In the present invention, the restraining mechanism 8 includes a first fixed frame 801, one of the support blocks 2 is fixedly connected to the first fixed frame 801, the first fixed frame 801 is internally rotatably connected to a connecting shaft 805, a storage roller 806 is fixedly connected to the connecting shaft 805, a strap 807 is wound around the storage roller 806, a spring 808 is wound around both sides of the connecting shaft 805, one end of the spring 808 is fixedly connected to the connecting shaft 805, and the other end is fixedly connected to the inner wall of the first fixed frame 801, the first fixed frame 801 is fixedly connected to the connecting shaft 805, and the other end is fixedly connected to the inner wall of the first fixed frame 801. A gusset plate 803 is engaged with the fixed frame 801, a pull block 802 is fixedly connected to the gusset plate 803, one end of the strap 807 is fixedly connected to the storage roller 806, and the other end is fixedly connected to the gusset plate 803, a second fixed frame 809 is fixedly connected to the other support block 2, a screw 810 is threadedly connected to the second fixed frame 809, and a screw hole 804 is provided on the gusset plate 803. By setting the first fixed frame 801, the pull block 802, the gusset plate 803, the screw hole 804, the connecting shaft 805, the storage roller 806 ... The strap 807, the spring spring 808, the second fixing frame 809 and the screw 810 are used. In actual operation, when it is necessary to puncture the affected part of the patient's body, after the affected part of the patient is anesthetized, the user can hold the pull block 802 and pull it, and the pull block 802 drives the buckle plate 803 to move together, and the buckle plate 803 moves to drive the strap 807 to gradually unfold, and the storage roller 806 and the connecting shaft 805 rotate accordingly, thereby causing the spring spring 808 to gradually contract, and the strap 807 will gradually fit the patient appropriately. The body part is restrained, and then the buckle plate 803 can be snapped into the corresponding slot inside the second fixed frame 809, and then the screw 810 is rotated to make the end of the screw 810 screw into the screw hole 804 of the buckle plate 803, so as to facilitate the fixation of the buckle plate 803 and then limit the strap 807, so as to facilitate the restraint and limitation of the corresponding body part of the patient when needed, reduce some minor deviations produced during the puncture process, ensure the puncture accuracy, and then ensure the subsequent treatment effect.

[0052] Working principle: When in use, the two mounting rods 1 can be installed at appropriate positions on both sides of the operating table or bed respectively, and then the two support blocks 2 can be slid on the two mounting rods 1 respectively. When the support block 2 is moved to the required appropriate position, the hand wheel 403 is rotated again, and the rotation of the hand wheel 403 drives the first screw rod 402 to rotate. Through the drive of the first screw rod 402, the interference block 401 can be continuously moved inside the support block 2 until the interference block 401 is clamped and interfered with the mounting rod 1, thereby facilitating the limit fixation of the support block 2, and then the limit fixation of the entire device.

[0053] When it is necessary to puncture the affected part of the patient's body, after the affected part of the patient is anesthetized, the user can hold the pull block 802 and pull it, then the pull block 802 drives the buckle plate 803 to move together, and the movement of the buckle plate 803 drives the strap 807 to gradually unfold, and the storage roller 806 and the connecting shaft 805 rotate accordingly, thereby causing the spring spring 808 to gradually shrink, and the strap 807 will gradually restrain the patient's appropriate body part. Then, the buckle plate 803 can be engaged into the corresponding slot inside the second fixing frame 809, and then the screw 810 is rotated to make the end of the screw 810 screw into the screw hole 804 of the buckle plate 803, so as to fix the buckle plate 803 and then limit the strap 807, so as to facilitate the restraint and limitation of the corresponding body part of the patient when needed, reduce some minor deviations generated during the puncture process, ensure the puncture accuracy, and thus ensure the subsequent treatment effect.

[0054] Then, the user can directly hold the ultrasound probe body 501 and aim the search end at the corresponding affected part of the patient. During this process, the ultrasound probe body 501 can automatically rotate forward and backward through the connecting rod 503, and the connecting rod 503 and the first spring 504 facilitate the free left and right swing of the ultrasound probe body 501. Furthermore, through the second spring 506 and the guide rod 507, the ultrasound probe body 501 can be automatically shaken up and down, so that the ultrasound probe body 501 can be grasped and controlled flexibly and the search angle of the ultrasound probe body 501 can be freely adjusted without changing the hand's grasping posture or sitting posture, etc., thereby ensuring the stability of holding the ultrasound probe body 501 and reducing the risk of the ultrasound probe body 501 falling and being damaged.

[0055] Furthermore, in actual operation, the sleeve 601 can be held and pressed in the direction of the mounting frame 3, so that the sleeve 601 is displaced relative to the sleeve rod 603, and the movement of the sleeve 601 drives the connecting plate 602 to move together, and the third spring 605 is compressed at the same time until the limiting tooth 604 at the end of the sleeve rod 603 is disengaged from the tooth groove part inside the sleeve 601. At this time, the sleeve 601 can be rotated to facilitate adjusting the connecting plate 602 to the required appropriate angle, and then the sleeve 601 is released. Under the action of the third spring 605, the limiting tooth 604 is re-engaged into the tooth groove part inside the sleeve 601 to fix the connecting plate 602.

[0056] After adjusting the connecting plate 602, the flexible rod 701 can be directly held and bent to adjust, so as to facilitate the docking block 703 and the placement frame 702 to move together. After the placement frame 702 is moved to an approximate position, the rotating wheel 705 can be held and rotated, and the rotating wheel 705 rotates to drive the second screw rod 706 to rotate together. As the second screw rod 706 rotates, the moving block 707 is driven to continuously move up and down inside the placement frame 702, thereby driving the installation sleeve 708 and the puncture needle 704 to move together, and cooperating with the dial 710 provided on the placement frame 702, it is convenient to make the insertion needle 704 extend out of the placement frame 702 to a suitable length. Afterwards, when the puncture needle 704 is actually used for the puncture operation, the steering ball 709 is used to facilitate the real-time adjustment of the angle of the puncture needle 704, so that the puncture angle and puncture depth can be appropriately adjusted at any time to meet the needs of different affected parts of the patient. When performing multiple groups of insertions, there is no need to prepare puncture components of various specifications, which makes the operation steps simpler.
