Description

Technical Field

[0001] This invention relates to the field of clinical medical technology, specifically to an adjustable anesthesia-assisted positioning and puncture device for ultrasound anesthesia. Background Technology

[0002] Aspiration, a common medical surgical term, is a diagnostic and treatment technique that involves inserting a needle into a body cavity to extract secretions for testing, injecting gas or contrast agents into the cavity for imaging examinations, or injecting medication into the cavity. The purposes of aspiration include blood sampling, blood transfusions, intravenous infusions, and catheter placement for angiography.

However, when performing puncture manually, unexpected situations may occur during the procedure, such as the doctor becoming too tired and experiencing blurred vision, or the doctor's hand tremors. These situations may lead to inaccurate positioning in the early stages, thus affecting the subsequent puncture results. Summary of the Invention

[0008] Preferably, a third telescopic member is installed on the inner wall of the bracket, a movable frame is fixed to the output end of the third telescopic member, a fourth telescopic member is installed on the inner wall of the movable frame, and the output end of the fourth telescopic member is fixed to the movable block.

[0009] Preferably, a toothed belt is fixed on the outer wall of the rotating plate, and a second drive source is installed at the top of the moving block. The output end of the second drive source passes through the inner top wall of the moving block and is fixed with a gear, which meshes with the toothed belt.

[0010] Preferably, the movable block has a connecting hole and a plurality of mounting holes.

[0011] Preferably, the prismatic clamp has a connecting groove that matches the arc-shaped clamp, and a rubber pad is fixed to one end of both the arc-shaped clamp and the prismatic clamp.

[0012] Preferably, the end of the bidirectional screw away from the first driving source is rotatably connected to the bracket, both ends of the limiting post are fixed to the bracket, and the bottom end of the bracket is provided with a moving groove that matches the connecting block.

[0013] Preferably, both ends of the movable frame and the movable block are fixed with stabilizing blocks, and both ends of the inner wall of the bracket and the movable frame are provided with stabilizing grooves that match the stabilizing blocks.

[0014] Preferably, a third driving source is installed on the inner wall of the rotating plate, the output end of the third driving source is fixed to the mounting plate, and a first telescopic member is installed at the top of the prismatic clamp, the output end of the first telescopic member is fixed to the support plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In this invention, the second telescopic component enables flexible switching between a prismatic clamp and an arc-shaped clamp. The optimal clamping method can be selected based on the different shapes of the operating table or the patient's body surface. The prismatic clamp is suitable for operating tables with flat or regular edges. The arc-shaped clamp can be hidden within the connecting groove by retracting the second telescopic component, ensuring a flat clamping surface. When facing an arc-shaped or irregular body surface area, the second telescopic component pushes the arc-shaped clamp out of the prismatic clamp to form a wraparound clamping action. Combined with a rubber pad to increase friction, this switching design significantly reduces the difficulty of installation and disassembly, shortens preoperative preparation time, and enhances the device's adaptability to different surgical scenarios. Through the fifth telescopic component and the pressure ring, when the fifth telescopic component drives the pressure ring downwards, its uniform downward pressure can slightly fix the local skin and subcutaneous soft tissue in the puncture area, reducing target position deviation caused by skin traction and tissue elastic deformation during puncture. This ensures that the actual puncture point and the ultrasound positioning point remain highly aligned, effectively reducing the risk of accidental injury to important tissue structures such as blood vessels and nerves, and improving surgical safety.

[0017] 2. In this invention, multiple sets of drive and transmission structures achieve precise and adjustable puncture positioning across all dimensions. The third telescopic component drives the moving frame to move, and the fourth telescopic component drives the moving block to move within the moving frame, completing the positioning of the positioning point or puncture point along the XY axis in the plane. The operation of the second drive source drives the gear to rotate, thereby driving the meshing toothed belt to rotate, which in turn drives the rotating plate to rotate within the moving block, achieving horizontal adjustment of the puncture or positioning angle. Furthermore, the operation of the third drive source can directly drive the mounting plate to rotate, further fine-tuning the tilt angle of the puncture or positioning. This composite control mode of "planar positioning + angle adjustment" completely eliminates the reliance on the doctor's experience, effectively avoiding positioning deviations caused by human factors such as hand tremors and fatigue, significantly improving the accuracy and controllability of puncture. In addition, the setting of stabilizing blocks and stabilizing grooves increases the stability of the moving frame and moving block, avoiding the problem of damage caused by the third and fourth telescopic components being supported alone, resulting in stronger stability.

[0018] 3. In this invention, the spacing between the two sets of prismatic clamps is adjusted through a driving structure, which can be adapted to operating tables of different sizes. The operation of the first driving source drives the bidirectional screw to rotate, so that the two moving plates move towards or away from each other under the limitation of the limiting post. The spacing between the two sets of support plates is adjusted synchronously through the connecting block. The first telescopic component can adjust the height of the prismatic clamps to ensure the fit between the device and the operating table. This adaptive adjustment design allows one device to meet the needs of different departments and operating tables of different specifications. Attached Figure Description

[0027] 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.

[0028] Example 1: As Figures 1-6As shown, the present invention provides a technical solution: an adjustable anesthesia-assisted positioning puncture device for ultrasound anesthesia, including a support 1, two support plates 2 symmetrically arranged on both sides of the bottom end of the support 1, a prismatic clamping plate 3 arranged below the support plate 2, a moving block 13 arranged inside the support 1, a rotating plate 16 rotatably connected inside the moving block 13, an mounting plate 20 rotatably connected inside the rotating plate 16, an adjustment structure 5 for clamping the arc-shaped surface arranged on the outer side of the prismatic clamping plate 3, a driving structure 8 for driving the two sets of support plates 2 to move in opposite directions, a fifth telescopic member 24 installed at the bottom end of the moving block 13, and a pressure ring 25 fixed at the output end of the fifth telescopic member 24.

[0029] In this embodiment, the core design of "base adaptive fixation + puncture all-dimensional positioning" fundamentally solves the problems of inaccurate positioning and significant influence from human factors during manual puncture. It achieves rapid adaptation of the device to the operating table, precise positioning of the puncture point, and stable control of the puncture process, significantly improving the safety and accuracy of ultrasound anesthesia puncture. The device uses the bracket 1 as the main load-bearing structure and is fixed to the edge of the operating table by the prismatic clamp 3 below the support plate 2. The adjustment structure 5 can switch the clamping method according to the shape of the clamping surface (planar or arc-shaped) to ensure stable installation of the device. The drive structure 8 can adjust the distance between the two sets of support plates 2 to adapt to operating tables of different sizes. During the positioning stage, the rotating plate 16 and the mounting plate 20 in the moving block 13 can achieve multi-dimensional adjustment of the puncture angle, so that the puncture needle is accurately aligned with the target point. The fifth telescopic component 24 drives the pressure ring 25 to press down, fixing the initial position of the puncture needle and preventing deviation during the puncture process.

[0030] Example 2: As Figures 1-6 As shown, the adjustment structure 5 includes a fixing frame 501 fixed to one end of the prismatic clamping plate 3. A second telescopic member 502 is installed on the end of the fixing frame 501 facing the prismatic clamping plate 3. An arc-shaped clamping plate 503 is fixed to the output end of the second telescopic member 502. One end of the arc-shaped clamping plate 503 passes through the prismatic clamping plate 3. The drive structure 8 includes a first drive source 801 installed at one end of the bracket 1. A bidirectional screw 802 is fixed to the output end of the first drive source 801. Moving plates 803 are threaded to both ends of the outer wall of the bidirectional screw 802. The ends of the two moving plates 803 away from the bidirectional screw 802 are slidably connected to a limit post 804. Connecting blocks 805 are fixed to both sides of the bottom end of the two moving plates 803. The bottom end of the connecting blocks 805 passes through the bracket 1 and is fixed to the support plate 2.

[0031] In this embodiment, flexible switching between the prismatic clamp 3 and the arc-shaped clamp 503 is achieved, significantly improving the device's adaptability to different clamping surfaces. Simultaneously, the rubber pad 7 enhances clamping stability and safety, preventing damage to the patient's skin or the operating table. When clamping a planar structure, the second telescopic member 502 retracts, causing the arc-shaped clamp 503 to be hidden within the communicating groove 6 of the prismatic clamp 3, allowing the prismatic clamp 3 to directly contact the plane and ensure a flat clamping surface. When facing an arc-shaped or irregular body surface area, the second telescopic member 502 pushes the arc-shaped clamp 503 outwards, engaging with... The rhomboid clamps 3 work together to form a ring-shaped clamping mechanism, and the rubber pads 7 increase friction and improve fixation stability. The spacing between the two sets of support plates 2 is adjustable, allowing the device to quickly adapt to operating tables of different sizes, thus improving the device's versatility and clinical application range. After the first drive source 801 is started, it drives the bidirectional screw 802 to rotate, causing the two moving plates 803 to move towards or away from each other under the limitation of the limiting post 804. Through the two sets of connecting blocks 805, the two sets of support plates 2 move synchronously, thereby adjusting the spacing between the two sets of rhomboid clamps 3 until it matches the size of the operating table.

[0032] Example 3: As Figures 1-6 As shown, a third telescopic member 10 is installed on the inner wall of the bracket 1. A movable frame 11 is fixed to the output end of the third telescopic member 10. A fourth telescopic member 12 is installed on the inner wall of the movable frame 11. The output end of the fourth telescopic member 12 is fixed to the movable block 13. A toothed belt 17 is fixed to the outer wall of the rotating plate 16. A second drive source 18 is installed at the top of the movable block 13. The output end of the second drive source 18 passes through the inner top wall of the movable block 13 and is fixed with a gear 19. The gear 19 meshes with the toothed belt 17. A connecting hole 23 is opened in the movable block 13. Multiple mounting holes 22 are opened in the movable block 13. A connecting groove 6 matching the arc-shaped clamp 503 is opened in the prismatic clamp 3. Rubber pads 7 are fixed to one end of both the prism clamp 3 and the prism clamp 3; the end of the bidirectional screw 802 away from the first drive source 801 is rotatably connected to the bracket 1; both ends of the limiting post 804 are fixed to the bracket 1; the bottom end of the bracket 1 is provided with a moving groove 9 that matches the connecting block 805; both ends of the moving frame 11 and the moving block 13 are fixed with stabilizing blocks 14; both ends of the inner walls of the bracket 1 and the moving frame 11 are provided with stabilizing grooves 15 that match the stabilizing blocks 14; a third drive source 21 is installed on the inner wall of the rotating plate 16; the output end of the third drive source 21 is fixed to the mounting plate 20; the top end of the prism clamp 3 is installed with a first telescopic member 4; the output end of the first telescopic member 4 is fixed to the support plate 2.

[0033] In this embodiment, precise positioning of the puncture point along the X and Y axes in the plane is achieved. Through the coordinated action of the third telescopic member 10 and the fourth telescopic member 12, the moving block 13 can move freely within the support 1, precisely aligning with the target puncture area. The third telescopic member 10 drives the moving frame 11 to move, completing the positioning in the X-axis direction. The fourth telescopic member 12 drives the moving block 13 to move within the moving frame 11, completing the positioning in the Y-axis direction. The cooperation between the stabilizing block 14 and the stabilizing groove 15 ensures structural stability during movement, preventing shaking from affecting positioning accuracy. Horizontal adjustment of the puncture angle is achieved. Through the meshing transmission of the gear 19 and the toothed belt 17, the rotating plate 16 can rotate smoothly within the moving block 13, precisely adjusting the horizontal angle of the puncture needle. After the second drive source 18 is started, it drives the gear 19 to rotate. Because the gear 19 is meshed with the toothed belt 17 on the outer wall of the rotating plate 16, it drives the toothed belt 17 to rotate, thereby driving the rotating plate 16 to rotate within the moving block 13, adjusting the horizontal angle of the puncture needle, so that the puncture path is precisely aligned with the target point; it provides a standardized installation interface for the puncture needle and the ultrasound probe, which facilitates the quick replacement of consumables of different specifications, while ensuring the coaxiality of the puncture needle and the ultrasound image, improving the positioning accuracy; the puncture needle is fixed on the mounting plate 20 through the mounting hole 22, and the ultrasound probe is coaxially set with the puncture needle through the connecting hole 23, ensuring that the ultrasound image and the puncture path are precisely corresponded, realizing the precise guidance of "what you see is what you puncture"; the smoothness of operation of the adjustment structure 5 is optimized. For clamping safety, the connecting groove 6 provides precise motion guidance for the arc-shaped clamping plate 503, while the rubber pad 7 enhances clamping stability and comfort. Driven by the second telescopic component 502, the arc-shaped clamping plate 503 smoothly extends or retracts along the connecting groove 6, preventing jamming during movement. The rubber pad 7 increases the friction of the clamping surface, while also providing cushioning and some deformation protection. This ensures the operational stability and reliability of the drive structure 8; the rotation of the bidirectional screw 802 and the movement of the moving plate 803 are effectively constrained, preventing offset and swaying during movement. Driven by the first drive source 801, the bidirectional screw 802 rotates, the moving plate 803 moves smoothly along the limiting post 804, and the connecting block 805 moves synchronously along the moving groove 9, driving the support... The support plate 2 precisely adjusts the spacing, ensuring a smooth and reliable process. This enhances the stability of the moving frame 11 and moving block 13 during movement. The cooperation between the stabilizing block 14 and the stabilizing groove 15 effectively prevents positioning deviations caused by shaking. When the moving frame 11 and moving block 13 move under the drive of the telescopic component, the stabilizing block 14 remains embedded in the stabilizing groove 15, limiting vertical shaking and ensuring smooth movement and positioning accuracy. It achieves fine adjustment of the puncture angle and adaptive adjustment of the device height. Through the synergistic effect of the third drive source 21 and the first telescopic component 4, the accuracy of puncture and the adaptability of the device are further improved. The third drive source 21 directly drives the mounting plate 20 to rotate, finely adjusting the tilt angle of the puncture needle.The first telescopic component 4 adjusts the height of the prismatic clamp 3, allowing the device to fit more closely to the operating table and improving overall stability.

[0034] In this invention, the adjustable anesthesia-assisted positioning puncture device for ultrasound anesthesia is used as follows: First, before surgery, the first drive source 801 is activated according to the size of the operating table. The first drive source 801 drives the bidirectional screw 802 to rotate, causing the two moving plates 803 to move towards or away from each other under the limitation of the limiting post 804. The distance between the two sets of support plates 2 is adjusted synchronously through the connecting block 805. After adjusting to the distance matching the operating table, the clamping method is selected according to the edge of the operating table or the shape of the patient's body surface: If it is a planar structure, the second telescopic member 502 retracts, so that the arc-shaped clamp 503 is hidden in the communicating groove 6 of the prism clamp 3, and the prism clamp 3 directly clamps; if it is an arc structure, the second telescopic member 502 pushes the arc-shaped clamp 503 to extend, forming a ring-shaped clamping, and the rubber pad 7 increases the friction to complete the device fixation; then the first telescopic member 4 is activated to adjust the height of the prism clamp 3 so that the device fits the operating table. During positioning, first activate the third telescopic component 10, which drives the moving frame 11 to move. Then activate the fourth telescopic component 12, which drives the moving block 13 to move within the moving frame 11, completing the XY axis positioning of the puncture point or positioning point. Next, activate the second drive source 18, which drives the gear 19 to rotate. Because the gear 19 meshes with the toothed belt 17 on the outer wall of the rotating plate 16, it drives the toothed belt 17 to rotate, thereby driving the rotating plate 16 to rotate within the moving block 13, adjusting the puncture or positioning angle. Then activate the third drive source 21, which directly drives the mounting plate 20 to rotate, further fine-tuning the tilt angle of the puncture needle or positioning. After positioning is completed, activate the fifth telescopic component 24, which drives the pressure ring 25 to press down, fixing the initial position of the puncture needle and ensuring stability during the puncture process. The piercing mechanism and positioning mechanism can be installed on the mounting plate 20 through the cooperation of the mounting hole 22 and the connecting hole 23. The first driving source 801, the second driving source 18 and the third driving source 21 in this invention are components such as motors, which only need to drive the corresponding components at their output ends to rotate. The first telescopic member 4, the second telescopic member 502, the third telescopic member 10, the fourth telescopic member 12 and the fifth telescopic member 24 are components such as electric telescopic rods and electric push rods, which only need to drive the corresponding components at their output ends to move. They are not limited. This invention also has an external power supply device and a controller for supplying power and controlling the first driving source 801, the second driving source 18, the third driving source 21, the first telescopic member 4, the second telescopic member 502, the third telescopic member 10, the fourth telescopic member 12 and the fifth telescopic member 24. Therefore, they will not be described in detail.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
