Description

Technical Field

[0001] This invention relates to the field of puncture needle technology, specifically to a puncture auxiliary device for anesthesia in the anesthesiology department. Background Technology

[0002] Anesthesia puncture assist devices are a class of medical devices used to assist anesthesia puncture operations, improve puncture accuracy and safety. Their core function is to provide guidance, stable support or visual guidance for the puncture needle, reduce the risk of operational errors, increase the success rate of puncture on the first attempt, reduce damage to surrounding tissues, and reduce the risk of complications.

[0003] Before using the puncture assist device, a preoperative assessment and instrument preparation are completed. Medical personnel assist the patient in positioning themselves appropriately to expose the puncture area. Standard disinfection and draping are performed around the puncture point, and local anesthesia is administered. The assist device is then used to fix the puncture direction and confirm the puncture depth. The puncture needle is then slowly inserted along the pre-set path. Once the target location is confirmed, anesthetic drugs are injected or an indwelling catheter is inserted. After the procedure, the puncture needle is withdrawn, and the puncture point is fixed. Existing puncture assist devices are prone to slight deviation and wobbling of the puncture needle during insertion, making it difficult for the device to correct deviation and monitor its status in real time. Rigid clamping can also damage the puncture needle, resulting in low puncture accuracy and the risk of accidentally injuring human tissue. In addition, the assist device lacks limiting and axial locking structures, making it difficult to control the puncture depth. Components are also prone to movement, posing safety hazards. Furthermore, the overall operation and debugging are cumbersome and inconvenient for clinical use.

[0004] To address the above issues, a puncture assistance device for anesthesia in the anesthesiology department is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a puncture assistance device for anesthesia in the anesthesiology department. By using this device, the problems mentioned above are solved, such as the puncture needle being prone to slight deviation, the device being difficult to correct and monitor, rigid clamping being prone to damaging the instrument and causing tissue damage, the lack of limiting and locking functions, difficulty in controlling the puncture depth, cumbersome operation procedures, and poor safety and practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a puncture auxiliary device for anesthesia in anesthesiology, comprising a supporting column, a clamping base fixedly connected to the bottom of the supporting column, a clamping locking bolt threaded to one end of the clamping base, a movable clamping plate slidably connected inside the clamping base, a lifting slider slidably connected to the inner wall of the supporting column, a rotating locking shaft provided at one end of the lifting slider, an angle adjustment component rotatably connected inside the rotating locking shaft, a guide correction component inserted inside the angle adjustment component, a locking adjustment component provided at the end of the guide correction component, a puncture needle inserted inside the guide correction component, a threaded rod threadedly connected inside the lifting slider, and an adjusting handwheel fixedly connected to the top of the threaded rod.

[0007] Furthermore, the angle adjustment assembly includes a support shaft rotatably connected inside the rotary locking shaft, an arc-shaped alloy track fixedly connected to the end of the support shaft, and a sliding support seat slidably connected inside the arc-shaped alloy track.

[0008] Furthermore, a threaded sleeve is provided through the interior of the sliding support, and a threaded push rod is threadedly connected inside the threaded sleeve. A locking knob is fixedly connected to the end of the threaded push rod, and a mounting base is fixedly connected to one end of the sliding support.

[0009] Furthermore, the guiding and correcting assembly includes a medical positioning guide cylinder inserted into the mounting base. A rubber bushing is fixedly connected to the surface of the medical positioning guide cylinder, and an axial limiting flange is also provided on the surface of the medical positioning guide cylinder, with the axial limiting flange located below the rubber bushing.

[0010] Furthermore, an outer guide cylinder is fitted onto the outer surface of the rubber bushing, and an annular groove is formed on the outer surface of the outer guide cylinder. A limit adjustment frame is rotatably connected to the inner wall of the outer guide cylinder. The bottom of the limit adjustment frame is hollow, and an ear block is provided on the inner wall of the bottom. A tapered guide bushing is fixedly connected to the bottom end of the inner wall of the outer guide cylinder.

[0011] Furthermore, the bottom of the tapered guide bushing is fixedly connected to multiple elastic grippers, the ends of the multiple elastic grippers are in contact with the middle surface of the puncture needle, the tapered guide bushing is disposed below the limit adjustment frame, the inner wall of the limit adjustment frame is fixedly connected to an annular circuit board, and the inner wall of the annular circuit board is fixedly connected to multiple photoelectric sensors.

[0012] Furthermore, the inner wall of the limiting adjustment frame is provided with multiple electric push rods, the output end of the electric push rod is fixedly connected to a push block, the push block is in contact with the top surface of the puncture needle, the bottom end of the outer guide cylinder is inserted with multiple locking positioning pins, and the axial limiting flange is set on the movement trajectory of the locking positioning pins.

[0013] Furthermore, the locking adjustment assembly includes a guide rail fixedly connected to the surface of the outer guide cylinder, with an elastic tooth elastically connected to one top end of the guide rail, and an axial groove slidably connected to the surface of the guide rail.

[0014] Furthermore, a pressing block is fixedly connected to the top of the axial slide groove, and a row of teeth is fixedly connected to one end of the pressing block. The row of teeth meshes with the elastic locking teeth, and an axial pressing ring is fixedly connected to the bottom of the axial slide groove.

[0015] Furthermore, the bottom of the axial pressing ring is rotatably connected to a plurality of friction contact plates, which are disposed inside the mounting base. The bottom end of the plurality of friction contact plates is rotatably connected to a rotating shaft, and the surface of the rotating shaft is provided with a telescopic frame. The end of the telescopic frame away from the friction contact plate is hinged to the outer guide cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This device, with its angle adjustment component, can flexibly adjust the clamping range according to the thickness of the operating table edge, and is fixed to the side of the operating table, fundamentally preventing slippage and shaking during operation, thus significantly improving overall stability. Combined with the angle adjustment component consisting of a rotating locking shaft and an arc-shaped alloy track, it can achieve continuous and precise adjustment of the puncture pitch angle, adapting to patients in different positions and body types, and meeting the needle insertion requirements of various puncture procedures such as spinal anesthesia and nerve blocks, greatly expanding the clinical applicability of the device.

[0017] By setting up a guide correction component, a double-layer guide structure is formed by a medical positioning guide cylinder and an outer guide cylinder. Combined with the bottom elastic gripper, the puncture needle is flexibly held. This effectively limits the radial swing of the needle body and ensures that the puncture proceeds in a straight line. It also avoids the problems of scratching and wearing the puncture needle caused by traditional rigid clamping. Medical staff can complete the puncture operation by pushing the outer guide cylinder. At the same time, the photoelectric sensor integrated in the limit adjustment frame can monitor the posture and movement of the puncture needle in real time. When a slight deviation of the needle body is detected, the electric push rod drives the push block to correct the posture of the needle body from multiple directions, quickly correcting the deviation of the puncture path. This effectively reduces the risk of the needle body deviating from the target area and accidentally injuring human tissue, and comprehensively improves the accuracy and safety of the puncture operation.

[0018] By setting up a locking adjustment component, the maximum travel depth of the puncture needle can be controlled, preventing errors such as punctures that are too deep or too shallow. At the same time, when the puncture needle deviates at a large angle, it can also be locked by a friction locking structure composed of elastic locking teeth, toothed teeth, and friction contact plates to prevent further risks. Moreover, medical staff can complete the locking and unlocking actions with one hand without the need for other auxiliary tools. It can lock the working position of the guide component and the puncture needle to prevent component slippage and axial movement of the needle body. It can also be quickly reset when the operation is completed or parameters need to be adjusted, simplifying the preoperative adjustment and intraoperative emergency operation procedures, effectively shortening the preparation time, and improving the overall efficiency of anesthesia puncture.

[0021] 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.

[0022] like Figures 1-15As shown, the following preferred technical solution is provided: A puncture assistance device for anesthesia in anesthesiology departments includes a supporting column 1. The supporting column 1 serves as the basic load-bearing component of the device, providing a stable mounting base and positioning constraints for the entire device, ensuring the regularity and operational stability of the device, and providing a stable basic support for clinical puncture operations. A clamping base 2 is fixedly connected to the bottom of the supporting column 1. The clamping base 2 serves as the bottom carrier of the device, used to stably install the device at the edge of the operating table, improving the overall flexibility of the device, and also providing a stable mounting base for the supporting column 1, avoiding instability factors such as overall device displacement and shaking during puncture operations, and providing a stable load-bearing base for puncture operations. One end of the clamping base 2 is threadedly connected to a clamping lock. Bolt 3 and movable clamping plate 4 are slidably connected inside the clamping base 2. The clamping locking bolt 3 is a clamping drive and locking component. It relies on thread transmission to realize the feeding push and completes the clamping action in conjunction with the movable clamping plate 4. This allows the clamping base 2 to flexibly adjust the clamping stroke according to the thickness of the operating table edge, so as to realize the effective locking of the device and the bed body, improve the device's adaptability to different specifications of bed edges, and prevent the device from slipping and loosening during operation. The inner wall of the support column 1 is slidably connected to the lifting slider 5. The lifting slider 5 is the load-bearing sliding component in the support column 1. It realizes vertical linear sliding along the support column 1 and adjusts the parallel height between the device and the patient by its own lifting height to adapt to different patient positions and puncture site height requirements. One end of the lifting slider 5 is equipped with a rotary locking shaft 11. The rotary locking shaft 11 serves as a rotary connection and locking component, establishing a rotary connection structure between the lifting slider 5 and the device. It provides a rotational reference for the device, enabling fine-tuning of the puncture angle and locking after adjustment to prevent accidental deviation. The rotary locking shaft 11 internally connects to an angle adjustment component 6. The angle adjustment component 6 is a functional component used to adjust the puncture pitch angle. Through rotational coordination and angle adjustment, it allows for continuous and precise adjustment to match the needle insertion angle requirements for different patient positions in clinical practice, ensuring that the needle insertion trajectory conforms to treatment guidelines and improving the puncture operation. For precision, the angle adjustment component 6 is internally connected to a guide correction component 7. The guide correction component 7 provides a guiding basis for the travel direction of the puncture needle 12 in the auxiliary device. The device uses low-voltage DC power supply. The sensor needs to be calibrated before use. It is compatible with conventional anesthesia puncture needle 12 and standard operating table edge. It can form radial limit and centering constraint on puncture needle 12, effectively suppressing problems such as needle body shaking and needle insertion deviation. During the insertion of puncture needle 12, if it is squeezed or deviated, the guide correction component 7 can slightly correct abnormal puncture path, reduce the operational risk caused by needle insertion deviation, and ensure the smooth operation of puncture. The end of the guide correction component 7 is equipped with a locking adjustment component 8. The locking adjustment component 8 serves as a position control and status locking component, capable of locking and fixing the extension length and working position of the guide correction component 7 and the puncture needle 12. This prevents component displacement and needle movement during puncture, and also allows for manual locking by medical personnel when significant needle deviation occurs, ensuring the safety and stability of the puncture operation. It can also be flexibly unlocked and reset, facilitating readjustment of puncture parameters by medical personnel based on the on-site conditions. The puncture needle 12 is inserted into the guide correction component 7, serving as the direct execution component for the anesthesia puncture operation. Under the limiting guidance of the guide correction component 7... After completing the puncture and needle insertion, anesthesia is administered. The internal thread of the lifting slider 5 is connected to a threaded rod 9, which is the power transmission component that enables the vertical lifting of the lifting slider 5. It can convert its own rotation into linear driving force to drive the lifting slider 5 to slide up and down along the inner wall of the support column 1, providing power support for the height adjustment of the auxiliary device and ensuring smooth and precise operation of the lifting action. The top of the threaded rod 9 is fixedly connected to an adjustment handwheel 10. The adjustment handwheel 10 is a manual control component and is the part where medical staff apply force. By rotating the adjustment handwheel 10, the threaded rod 9 can be driven to rotate, and the overall height of the device can be easily adjusted. The operation is simple and labor-saving, meeting the needs of rapid operation in the operating room. The angle adjustment component 6 is used to adjust the deflection angle of the auxiliary device, which can realize stepless fine adjustment of the puncture pitch angle. It can flexibly match the standard needle insertion angle requirements of different clinical puncture procedures such as spinal anesthesia, nerve block, and local anesthesia. At the same time, it can adapt to the puncture point requirements of patients with different body types and different lying positions, greatly expanding the clinical application range of the device. It can ensure the accuracy and standardization of needle insertion of puncture needle 12. Meanwhile, the adjustment process is smooth and without jamming or stuttering. Medical staff can complete the angle adjustment with one hand. The operation is simple and convenient, effectively shortening the preoperative adjustment time, improving the overall efficiency of puncture operation and ensuring the puncture effect. The guide correction component 7 limits the radial travel of the puncture needle 12, effectively suppressing problems such as needle shaking, swaying, and radial deviation during needle insertion, ensuring that the puncture needle 12 always advances along a straight trajectory. Secondly, the guide correction component 7 can correct the path of the puncture needle 12 in real time during the puncture process. When a slight deviation occurs during needle insertion, the posture of the puncture needle 12 can be corrected in time to prevent the needle from deviating from the target puncture area, reduce the probability of accidentally injuring human tissues and organs, and improve the accuracy and safety of puncture operations. Furthermore, the smooth transition of the inner wall of the guide correction component 7 can reduce the frictional resistance of the puncture needle 12 during its movement, making the needle insertion process smoother and gentler, reducing the stinging and discomfort caused by needle shaking to the patient, and improving the patient's treatment experience. The locking adjustment component 8 can lock and fix the axial extension length and working position of the guide correction component 7 and the internal puncture needle 12 in all directions. It can effectively prevent the puncture needle 12 from moving axially or the guide component from slipping throughout the puncture operation, firmly locking the preset puncture depth and working position, and eliminating operational errors such as puncture too deep or too shallow due to component displacement. At the same time, the locking adjustment component 8 can also lock the puncture needle 12 and maintain its current state when a large deviation is found and it cannot be corrected by the guide correction component 7. Then, it can be precisely removed by personnel to achieve controllable risks. In addition, the locking adjustment component 8 can accurately adapt to puncture sites of different depths to meet the needs of different anesthesia puncture depths. The adjustment method is simple and intuitive, and the parameters can be reset without the need for additional tools. It adapts to the ever-changing clinical operating conditions. At the same time, the operating end is clear and tactile and comfortable to hold. Medical staff can quickly complete a series of actions such as locking, unlocking, and fine adjustment, further improving the efficiency of clinical operation.

[0023] like Figures 3-5 As shown, the angle adjustment component 6 includes a support shaft 61 rotatably connected inside the rotary locking shaft 11. An arc-shaped alloy track 62 is fixedly connected to the end of the support shaft 61, and a sliding support seat 63 is slidably connected inside the arc-shaped alloy track 62. When medical staff prepare for puncture, the angle adjustment component 6 starts to operate. First, it adjusts the deflection angle of the arc-shaped alloy track 62 according to the patient's position, puncture site, and puncture angle. When the arc-shaped alloy track 62 is flipped, the support shafts 61 at both ends of the arc-shaped alloy track 62 begin to rotate inside the rotary locking shaft 11. As the arc-shaped alloy track 62 rotates to the appropriate puncture angle, the rotary locking shaft 11 is rotated to lock the support shaft 61. During complete puncture, the adjustment of the elevation angle lays the foundation for subsequent precise puncture operations.

[0024] like Figure 4 and Figure 5 As shown, a threaded sleeve 64 is provided through the interior of the sliding support 63. A threaded push rod 65 is threadedly connected inside the threaded sleeve 64. A locking knob 66 ​​is fixedly connected to the end of the threaded push rod 65. A mounting base 67 is fixedly connected to one end of the sliding support 63. Then, according to the patient's position, the deflection angle of the sliding support 63 in the arc-shaped alloy track 62 is adjusted. After determining the deflection angle, the threaded push rod 65 is rotated in the threaded sleeve 64 by rotating the locking knob 66. As the threaded push rod 65 moves continuously, it gradually passes through the sliding support 63 and contacts the inner wall of the arc-shaped alloy track 62, generating a contact and stopping the movement of the sliding support 63, achieving gapless locking and ensuring the output angle of the mounting base 67, thereby locking the puncture angle and ensuring the stability of the auxiliary device when the subsequent puncture needle 12 is inserted.

[0025] like Figure 4 and Figure 5 As shown, the guide correction assembly 7 includes a medical positioning guide cylinder 71 inserted into the mounting base 67. A rubber bushing 72 is fixedly connected to the surface of the medical positioning guide cylinder 71. An axial limiting flange 73 is also provided on the surface of the medical positioning guide cylinder 71, and the axial limiting flange 73 is located below the rubber bushing 72. After the angle adjustment assembly 6 completes the adjustment of the needle insertion angle, the guide correction assembly 7 starts to operate. The medical positioning guide cylinder 71, which is inserted into the mounting base 67, can be quickly disassembled and maintained. The rubber bushing 72 on the surface of the medical positioning guide cylinder 71 has the functions of buffering, shock absorption and anti-slip, which can effectively weaken the small vibrations generated during the puncture operation and avoid vibration transmission affecting the puncture accuracy. At the same time, the axial limiting flange 73 can achieve precise axial position limiting, restrict the axial movement of subsequent structures, and prevent the structure from over-positioning.

[0026] like Figures 5-8 As shown, an outer guide cylinder 74 is fitted onto the outer surface of the rubber bushing 72. An annular groove is formed on the outer surface of the outer guide cylinder 74. A limit adjustment frame 75 is rotatably connected to the inner wall of the outer guide cylinder 74. The bottom of the limit adjustment frame 75 is hollow, and an ear block is provided on the inner wall of the bottom. A conical guide bushing 76 is fixedly connected to the bottom end of the inner wall of the outer guide cylinder 74. The outer guide cylinder 74 is fitted over the rubber bushing 72, forming a double-layer guide structure, which improves the guiding accuracy and structural stability of the puncture needle 12 in the overall device. The rubber bushing 72 not only reduces the impact of vibration but also ensures that the outer guide cylinder 74 can be used for medical positioning guidance. The outer guide cylinder 74 moves smoothly to the outside of the outer guide cylinder 71. The annular groove on the surface of the outer guide cylinder 74 provides a basic space for subsequent locking. The limit adjustment frame 75 is connected to the outer guide cylinder 74 by the lug at the bottom. When the puncture needle 12 is inserted into the guide correction component 7, after the bottom of the puncture needle 12 is inserted into the medical positioning guide cylinder 71, the top of the puncture needle 12 contacts the conical guide bushing 76. Then, the limit adjustment frame 75 is manually rotated so that the lug at the bottom of the limit adjustment frame 75 rotates to the top of the puncture needle 12, thereby locking the puncture needle 12 to prevent it from being deflected or dislodged during the puncture process.

[0027] like Figures 7-10As shown, a plurality of elastic grippers 77 are fixedly connected to the bottom of the tapered guide bushing 76. The ends of the plurality of elastic grippers 77 are in contact with the middle surface of the puncture needle 12. The tapered guide bushing 76 is located below the limiting adjustment frame 75. An annular circuit board 78 is fixedly connected to the inner wall of the limiting adjustment frame 75. A plurality of photoelectric sensors 79 are fixedly connected to the inner wall of the annular circuit board 78. As the puncture needle 12 is inserted, the plurality of elastic grippers 77 adhere to the outer wall of the puncture needle 12 based on their own elastic properties, which can flexibly clamp and position the puncture needle 12. This can limit the radial displacement of the puncture needle 12, ensure the straightness of the puncture, and avoid damage to the puncture needle 12 body by rigid clamping. At the same time, the annular circuit board 78 inside the limiting adjustment frame 75 integrates and deploys a plurality of photoelectric sensors 79 to form an annular full-area perception and detection structure, which can monitor the position displacement, posture deviation and puncture travel status of the puncture needle 12 in real time, and provide real-time feedback on abnormal puncture operation, providing data monitoring support for precise puncture operation.

[0028] like Figures 6-10 As shown, the inner wall of the limit adjustment frame 75 is provided with multiple electric push rods 710. The output end of each electric push rod 710 is fixedly connected to a push block 711, which contacts the top surface of the puncture needle 12. Multiple locking and positioning pins 712 are inserted into the bottom end of the outer guide cylinder 74. The axial limit flange 73 is positioned on the movement trajectory of the locking and positioning pins 712. During the puncture correction operation, when multiple photoelectric sensors 79 detect a slight deviation in the puncture needle 12, the photoelectric sensors 79 and the electric push rods 710 are electrically connected via a controller (existing technology, not shown in the figure). Then, the multiple electric push rods 710 can extend and retract synchronously or independently, driving the push block 711 to precisely push and fine-tune against the top of the puncture needle 12. The bottom elastic gripper 77 enables multi-directional posture correction of the puncture needle 12, correcting minor deviations during the puncture process. Before the puncture operation, when the puncture needle 12 is inserted into the outer guide cylinder 74, the push block 711 will retract and avoid it by adhering to the surface of the puncture needle 12. After the puncture needle 12 is fixed to the outer guide cylinder 74, the push block 711 makes slight contact with the surface of the puncture needle 12. The locking positioning pin 712 at the bottom of the outer guide cylinder 74 can achieve hard limiting when the puncture needle 12 moves to the dangerous depth. The axial limiting flange 73 limits the movement of the locking positioning pin 712 to avoid excessive displacement or loosening of the locking structure, ensuring the reliability of the structural locking throughout the puncture operation and eliminating puncture deviation caused by loosening of the guide structure.

[0029] like Figures 5-14As shown, the locking adjustment assembly 8 includes a guide rail 81 fixedly connected to the surface of the outer guide cylinder 74. One end of the guide rail 81 is elastically connected to an elastic locking tooth 82, and the surface of the guide rail 81 is slidably connected to an axial groove 83. The locking adjustment assembly 8 relies on the guide rail 81 on the outer guide cylinder 74 as a sliding bearing base. The axial groove 83 can slide smoothly axially along the guide rail 81. The elastic locking tooth 82 at the end of the guide rail 81 has elastic reset and engagement locking functions. It can achieve dynamic engagement positioning through elastic deformation, eliminating the need for complex manual locking operations and simplifying the device adjustment process. At the same time, the guide rail 81 and the axial groove 83, together with the elastic locking structure, realize the adjustment and precise fixation of the axial position of the device, adapting to the puncture operation requirements of different depths and working conditions, ensuring the stability of puncture, and, when faced with a large degree of deviation of the puncture needle 12, can quickly lock the puncture needle 12 to avoid further risks.

[0030] like Figures 11-14 As shown, a pressing block 84 is fixedly connected to the top of the axial slide groove 83, and a toothed bar 85 is fixedly connected to one end of the pressing block 84. The toothed bar 85 meshes with the elastic locking tooth 82. An axial pressing ring 86 is fixedly connected to the bottom of the axial slide groove 83. When the puncture needle 12 reaches the target depth or deviates, medical staff can press the pressing block 84 to drive the toothed bar 85 to move. The elastic deformation of the elastic locking tooth 82 enables the toothed bar 85 to mesh and separate from the elastic locking tooth 82, thereby unlocking or locking the sliding state of the axial slide groove 83. When the toothed bar 85 and the elastic locking tooth 82 are fully meshed, the axial slide groove 83 can be rigidly positioned to prevent sliding displacement and ensure structural stability. The axial pressing ring 86 moves synchronously with the axial slide groove 83 in the annular groove on the surface of the outer guide cylinder 74.

[0031] like Figures 13-15 As shown, a plurality of friction contact plates 87 are rotatably connected to the bottom of the axial pressing ring 86. These friction contact plates 87 are disposed inside the mounting base 67. A rotating shaft 88 is rotatably connected to the bottom end of each friction contact plate 87. A telescopic frame 89 is provided on the surface of the rotating shaft 88. The end of the telescopic frame 89 away from the friction contact plates 87 is hinged to the outer guide cylinder 74. When the axial pressing ring 86 is subjected to downward force, it can drive the plurality of friction contact plates 87 to rotate and open / close along the rotating shaft 88, causing the friction contact plates 87 to tightly press against the interior of the mounting base 67. The contact surface relies on friction to achieve a tight connection between the locking adjustment component 8 and the mounting base 67. The telescopic frame 89 extends and retracts synchronously with the rotation of the friction contact plate 87, playing a role in linkage support and limiting guidance. It can stabilize the opening and closing angle of the friction contact plate 87, avoid uneven force on one side of the plate causing displacement or jamming, greatly improve the overall locking and fastening effect and structural stability of the device, effectively avoid puncture errors and safety hazards caused by equipment loosening or displacement during puncture operations, and ensure the accuracy, stability and safety of puncture operations.
