[0032] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example

[0034] like Figure 1 As shown, the inner opposite sides of the mounting plate 1 are slidably connected with clamping plates 43, and the upper surfaces of the two clamping plates 43 are rotatably connected with adjusting screws 5 through rotating shafts, and the outer side walls of the two adjusting screws 5 are respectively connected with the inner threads of the mounting plate 1;

[0035] The staff can adjust the two adjusting screws 5 on both sides according to the thickness of the workbench or bracket to which the device needs to be fixed, so that the two clamping plates 43 are extended to an appropriate length until the two clamping plates 43 can fit tightly against the upper and lower surfaces of the workbench or bracket. The clamping force of the clamping plates 43 on both sides on the workbench or bracket can stably fix the entire device in the target position, effectively preventing the device from being displaced or shaken during subsequent puncture operations, thereby ensuring the stability and accuracy of the puncture operation.

[0036] like Figures 1-9As shown, an ultrasonic interventional puncture device for imaging ultrasonic medicine is provided, comprising a mounting plate 1, the upper surface of which is provided with a through-type adjustment slot 2, a movable plate 3 being slidably connected to the upper surface of the mounting plate 1, an operating box 4 being fixedly connected inside the movable plate 3, the operating box 4 being a hollow structure, a catheter 6 being provided inside the operating box 4, a puncture assembly 7 being provided inside the catheter 6, a drainage tube 8 being provided on the upper surface of the interior of the puncture assembly 7; a baffle 9 being provided on the lower surface of the operating box 4 and on the opposite side below the catheter 6; a baffle 9 being fixedly connected on the opposite side of the outer wall of the catheter 6 Rack plate 10, the inner left side and the inner right side of the operation box 4 are both provided with movable grooves 11, the inner rear surfaces of the two movable grooves 11 are rotatably connected to gear 12 via a rotating shaft, the outer side walls of the two gears 12 are respectively meshed with the outer side walls of the two rack plates 10, and the centers of the front surfaces of the two gears 12 are fixedly connected to fixed rods 13, the front ends of the two fixed rods 13 extend to the front of the operation box 4, and are fixedly connected to gear 2 14, and the front surface of the operation box 4 and located between the two gears 2 14 are rotatably connected to gear 3 15 via a rotating shaft;

[0037] First, according to the position requirement of the patient's puncture site, push the movable plate 3 slidably connected to the upper surface of the mounting plate 1, so that the movable plate 3 slides along the adjustment slot 2, thereby driving the operation box 4 fixedly connected to the movable plate 3 to move to a suitable initial position. Then, since the front surface of the operation box 4 is located between the two gears 2 14, the two gears 3 15 connected by the friction resistance shaft can stably support the catheter 6. The staff can control the two gears 3 15 to rotate in opposite directions to drive the two gears 2 14 meshing therewith to rotate. When the gear 2 14 rotates, it will drive the fixed rod 13 fixed at its center to rotate synchronously, thereby making the gear 1 12 connected to the rear end of the fixed rod 13 rotate in the movable slots 11 on the left and right sides of the inside of the operation box 4. The rotation of the gear 12 will drive the rack plate 10 meshing therewith to move up and down, and finally realize the downward adjustment of the catheter 6 until the catheter 6 is accurately moved to the right according to the patient's body shape. The puncture site, then the two baffles 9 are opened to expose the puncture channel under the catheter 6, and the puncture assembly 7 is exposed to facilitate the puncture operation. At the same time, because the puncture assembly 7 is always inside the catheter 6, it can effectively avoid its contact with the external environment. The horizontal position of the operation box 4 can be adjusted by cooperating with the movable plate 3 and the adjusting slot 2 to meet the horizontal positioning requirements of different puncture sites. With the help of the transmission structure of gear three 15, gear two 14, gear one 12 and rack plate 10, the lifting and lowering of the catheter 6 can be accurately controlled to ensure accurate positioning of the puncture site. The gear three 15 connected to the friction resistance shaft can stably support the catheter 6 to prevent it from falling at the initial position, and the puncture assembly 7 is placed inside the catheter 6 to prevent external contamination, thereby improving the safety and cleanliness of the puncture operation. The setting of the baffle 9 can protect the bottom of the catheter 6 in the non-puncture state, further ensuring the standardization of the device during use.

[0038] like Figure 1 As shown, a plurality of sockets 21 are provided on the upper surface of the mounting plate 1 and located behind the adjustment slot 2, and a positioning pin 22 is provided on the upper surface of the movable plate 3 and located behind the operation box 4, and the bottom end of the positioning pin 22 extends to the interior of the middle socket 21;

[0039] At the same time, after the positioning pin 22 is inserted into the socket 21, it can effectively limit the sliding of the movable plate 3, thereby preventing the operation box 4 from accidentally sliding during the puncture process and affecting the puncture accuracy, thereby further ensuring the stability of the ultrasonic interventional puncture operation.

[0040] like Figure 2 、 Figure 5 and Figure 8 As shown, a groove 23 is provided at the bottom of the front surface of the operation box 4, and a gear column 24 is rotatably connected to the bottom of the inner rear surface of the groove 23 through a rotating shaft, and a gear column 25 is rotatably connected to the upper surface of the inner rear surface of the groove 23 through a rotating shaft. The front surface of the gear column 1 24 and the front surface of the gear column 2 25 are fixedly connected to a pulley 26, and the inner side walls of the two pulleys 26 are jointly connected to a transmission belt 27 for transmission. The upper surfaces of the two baffles 9 are fixedly connected to movable sleeves 28, and the top ends of the two movable sleeves 28 extend to the top of the movable plate 3. The front surfaces of the two movable sleeves 28 and the tops of the movable plates 28 are fixedly connected to L-shaped toggle plates 29 above the movable plate 3, and the opposite sides of the two L-shaped toggle plates 29 are fixedly connected to a plurality of tooth blocks 30, and the outer side walls of the gear column 1 24 are respectively meshed and connected between the plurality of tooth blocks 30;

[0041] When the catheter 6 moves to the designated puncture point, the pulley 26 fixedly connected to the front surface of the tooth column 2 is driven to rotate synchronously by rotating the tooth column 25. Since the pulley 26 on the front surface of the tooth column 1 24 and the pulley 26 of the tooth column 25 form a common transmission structure through the transmission belt 27 on the inner wall, when the pulley 26 of the tooth column 25 rotates, it will drive the pulley 26 of the tooth column 1 24 to rotate synchronously through the transmission belt 27, thereby causing the tooth column 1 24 to rotate around the shaft connected to the lower rear surface of the groove 23. In addition, because the outer wall of the tooth column 1 24 is connected to the two L-shaped toggle plates The multiple tooth blocks 30 fixed on the opposite sides of 29 are meshed and connected, so when the tooth column 24 rotates, the two L-shaped toggle plates 29 will be driven by the tooth blocks 30 to move horizontally in opposite directions. The movement of the L-shaped toggle plate 29 will drive the movable sleeve plate 28 to move synchronously, and finally the two baffles 9 fixed to the movable sleeve plate 28 will be separated to both sides, thereby opening to form a puncture channel for the puncture component 7 to pass through. At the same time, the retractable structure of the two movable sleeve plates 28 can cooperate with the catheter 6 to descend together, so that the entire process does not require contact with the puncture component 7, further ensuring the sterility of the device.

[0042] like Figure 5 、 Figure 6 and Figure 8 As shown, a toggle slot 16 is provided on the front surface of the mounting plate 1 and below the two gears 3 15. A limit slider 17 is slidably connected to the lower portion of the toggle slot 16. A main gear 18 is rotatably connected to the center of the front surface of the limit slider 17 via a rotating shaft. A connecting rod 19 is fixedly connected to the center of the front surface of the main gear 18. A rotating handle 20 is fixedly connected to the front end of the connecting rod 19.

[0043] When it is necessary to adjust the position of the catheter 6 and open the puncture channel, the staff first pulls up the rotating handle 20. Therefore, pulling the rotating handle 20 will drive the main gear 18 to slide upward along the toggle slot 16 along the limit slider 17 until the main gear 18 moves to a state of meshing with the right gear 2 14. At this time, turning the rotating handle 20 will drive the main gear 18 to rotate through the connecting rod 19. The rotation of the main gear 18 drives the right gear 2 14 meshed with it to rotate, and then drives the two gears 2 14 to rotate in the opposite direction. The two gears 2 14 rotate in the opposite direction to accurately move the catheter 6 to the designated puncture position. When the catheter 6 is positioned, the staff dials down The main gear 18 is moved so that the main gear 18 slides downward along the toggle slot 16 with the limit slider 17, disengaging from the meshing state with the right gear 2 14 and moving to mesh with the gear column 2 25. At this time, the rotating handle 20 is turned to drive the main gear 18 to rotate through the connecting rod 19, and finally the two baffles 9 are separated to both sides, opening the puncture channel. Thus, by rotating the handle 20 and the main gear 18 that can slide up and down, the lowering of the catheter 6 and the opening of the puncture channel are integratedly controlled. There is no need to switch different operating components, the operation is more consistent and convenient, and the operating steps and hand movement range of the staff are reduced, thereby further improving the convenience and stability of the device.

[0044] like Figure 4 and Figure 9 As shown, a through-type pressing groove 31 is symmetrically opened at the lower part of the interior of the catheter 6, and the inner side walls of the two pressing grooves 31 are slidably connected to the movable blocks 32, and the interiors of the two movable blocks 32 are slidably connected to the sliding plates 33, and the opposite sides of the two sliding plates 33 are fixedly connected to the support rods 34, and the opposite ends of the two support rods 34 extend to the opposite sides of the two movable blocks 32, and are fixedly connected to the arc-shaped clamping plates 35, and the opposite sides of the two sliding plates 33 are fixedly connected to the pressing blocks 36, and the opposite sides of the two pressing blocks 36 extend to the opposite sides of the two movable blocks 32, respectively. The opposite sides of the two sliding plates 33 and the opposite sides of the interiors of the two movable blocks 32 are respectively fixedly connected to a plurality of return springs 37.

[0045] When the puncture channel is opened, the two pressing blocks 36 are pressed by both hands at the same time. After the pressing block 36 is subjected to force, the sliding plate 33 will slide in the relative direction along the inside of the movable block 32, and the return spring 37 will be compressed. When the sliding plate 33 slides, it will drive the support rod 34 fixed on the opposite side to move synchronously, and the support rod 34 will push the arc-shaped clamping plate 35 at the opposite end toward the puncture assembly 7 until the inner side walls of the two arc-shaped clamping plates 35 are tightly fitted with the puncture assembly 7, thereby clamping and fixing the puncture assembly 7. After the puncture assembly 7 is stably clamped, the staff maintains the pressing state of the pressing block 36 and pushes the puncture assembly 7 to slide downward along the pressing groove 31 of the catheter 6. During the process of the puncture assembly 7 sliding down along the pressing groove 31 with the movable block 32, it always maintains a stable posture and direction until it pierces the catheter 6. The puncture channel below acts precisely on the designated puncture point to complete the puncture operation. After the puncture is completed, the pressing block 36 is released, and the return spring 37 pushes the sliding plate 33 to slide in the opposite direction under the action of the elastic restoring force, and then drives the arc clamping plate 35 to disengage from the puncture assembly 7 through the support rod 34, releasing the clamping state for subsequent removal or adjustment of the puncture assembly 7, thereby quickly achieving the clamping and loosening of the puncture assembly 7 through the cooperation of the pressing block 36 and the return spring 37. The operation is simple and flexible, and no additional tools are required. It adapts to the needs of rapid fixation during the puncture process. At the same time, the sliding cooperation between the movable block 32 and the pressing groove 31 provides a stable sliding trajectory for the puncture assembly 7, effectively preventing the puncture assembly 7 from deflecting or shaking during the sliding process, ensuring the accuracy of the puncture direction, and improving the safety and success rate of the puncture operation.

[0046] like Figure 3 、 Figure 4 and Figure 9 As shown, the inner lower surfaces of the two pressing grooves 31 are each provided with a sealing groove 38, and the lower surfaces of the two movable blocks 32 are fixedly connected with a sealing plate 39, and the lower surfaces of the two sealing plates 39 extend to the upper inner portions of the two sealing grooves 38 respectively;

[0047] When the worker presses the pressing block 36 and pushes the puncture assembly 7 to slide downward along the pressing groove 31, the sealing plate 39 will move downward synchronously with the movable block 32. Since the lower surface inside the pressing groove 31 is provided with a sealing groove 38 matched with the sealing plate 39, the lower surface of the sealing plate 39 will gradually extend above the inside of the sealing groove 38 during the downward movement of the sealing plate 39, and the outer side wall of the sealing plate 39 is always tightly fitted with the inner side wall of the sealing groove 38. When the movable block 32 slides to adjust the position in the pressing groove 31, the sealing plate 39 will also always move synchronously in the sealing groove 38. The sealing groove 38 provides a moving space for the sealing plate 39, avoids the sealing plate 39 from leaving the sealing position due to the sliding of the movable block 32, and thus continuously isolates the pressing groove 31 from the external environment, preventing dust, bacteria and other pollutants in the external air from entering the inside of the catheter 6 through the gap of the pressing groove 31 to contact the puncture assembly 7. Thus, through the close cooperation of the sealing plate 39 and the sealing groove 38, the internal and external communication of the pressing groove 31 can be effectively blocked, a continuous sterile environment is built for the puncture assembly 7 and the puncture channel, the risk of infection during the puncture process is reduced, the sterile requirement of the ultrasonic intervention puncture operation is met, and the practicability and safety of the device are further improved.

[0048] As shown in Figure 2 and Figure 7 , the inner front surface and the inner rear surface of the operation box 4 are both provided with a guide groove 40, and the opposite sides of the two pressing blocks 36 respectively extend into the two guide grooves 40.

[0049] When the worker moves the catheter 6, the two guide grooves 40 and the two pressing blocks 36 form a cooperative effect, and the opposite sides of the two pressing blocks 36 respectively extend into the two guide grooves 40. When the catheter 6 moves downward with the rack plate 10, the pressing block 36 will move downward along the inner side wall of the guide groove 40 synchronously until it is extended, which is convenient for the worker to control the puncture assembly 7 for subsequent puncture operation.

[0050] As shown in Figure 4 and Figure 5 , the lower surface of the catheter 6 is embeddedly installed with a magnet one 41, and the upper surface of the two baffles 9 is embeddedly installed with a magnet two 42. The lower surface of the two magnet ones 41 is respectively magnetically connected with the upper surface of the two magnet twos 42.

[0051] A magnet 1 41 is embedded in the lower surface of the catheter 6, and a magnet 2 42 is embedded in the corresponding position of the upper surface of the two baffles 9. When the two baffles 9 are in the closed state, the two magnets 2 42 are precisely aligned with the two magnets 1 41 and form a magnetic connection. The adsorption force between the magnets is used to firmly fix the two baffles 9 under the catheter 6 to prevent the baffles 9 from loosening or shifting during the movement of the device and the adjustment of the catheter 6, thereby ensuring the integrity and stability of the overall structure of the catheter 6. When a puncture operation is required, the staff controls the rotation of the gear column 2 25 through the main gear 18 to drive the two baffles 9 to separate to both sides. At this time, the magnet 2 42 moves with the baffle 9 and is separated from the magnetic connection with the magnet 1 41, opening the puncture channel for the puncture assembly 7 to slide down. After the puncture is completed, the reverse operation is performed to control the baffles 9 to close, and then the two movable sleeves 28 are pushed upward to make the magnetic Iron 2 42 will be accurately adsorbed with magnet 1 41 again to re-fix the catheter 6 and the baffle 9. Therefore, after each puncture operation, the staff will first remove the used puncture component 7 from the inside of the catheter 6. Since the fixation of the catheter 6 and the baffle 9 only relies on magnetic connection, there is no need to disassemble complex components. It is only necessary to directly replace the new sterile puncture component 7 and install it into the catheter 6, ensuring that the new component is compatible with the arc splint 35 and the pressing groove 31. After the replacement is completed, since the catheter 6, baffle 9 and magnet fixing structure are not affected by the puncture operation, the next puncture preparation process can be directly entered without replacing or repairing the overall structure of the catheter 6. The device can be reused by replacing the puncture component 7, which greatly reduces the consumables cost of the device, while shortening the preparation time for each operation and improving clinical use efficiency. It is especially suitable for high-frequency ultrasonic interventional puncture scenarios.

[0052] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
