Description

Technical Field

[0001] This invention relates to the field of probe support frame technology, specifically a multifunctional probe support frame for ultrasound-guided nerve block. Background Technology

[0002] The multifunctional probe support frame for ultrasound-guided nerve block is an auxiliary medical device. Its main function is to support and fix the ultrasound probe during ultrasound-guided nerve block, freeing the operator's hands, improving puncture accuracy, and reducing operator fatigue. Currently, when this device is used to perform ultrasound-guided nerve blocks on patients, the operator usually needs to manually support the ultrasound probe. The ultrasound image is easily affected by external factors and the operator's hand tremors, resulting in blurred images and increased artifacts. At the same time, when adjusting the height of the support, bolts are usually used for adjustment, which can easily cause the bolts to strip after long-term tightening, affecting the normal use of the support. Summary of the Invention

[0003] Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a multifunctional probe support frame for ultrasound-guided nerve blocks. After the ultrasound probe penetrates the interior of the first and second fastening support rings, tightening the screw block and nut continuously shortens the distance between the two rings. Through this continuous contraction, the compression block presses against the surface of the ultrasound probe, improving the fit between them. Once the ultrasound probe is fixed to the first and second fastening support rings, the connection between the sphere and the movable plate allows for multi-directional rotation and positioning of the probe. The movable plate's pitch angle is adjusted via a hinged structure between a shaft and the support plate. The rubber plate absorbs vibrations during operation through the first and second connecting blocks, preventing probe displacement and thus improving the stability and accuracy of ultrasound images during nerve block guidance. After the height of the support plate is adjusted, the fixing rod can be inserted through the slide plate and the moving seat, and the fastening fitting rod can be fitted into both ends of the fixing rod. The rubber sleeve increases the friction between the fastening fitting rod and the fixing rod, making it less likely for the fastening fitting rod to slide inside the fixing rod. After the fastening fitting rod and the fixing rod are fitted, the first and second fixing blocks increase the weight at both ends of the fixing rod. The elasticity of the first spring allows the weight of the second fixing block to pull the first spring, thus concentrating the weight at both ends of the fixing rod downwards, which prevents the moving seat from shifting inside the slide plate.

[0004] (II) Technical Solution To solve the above technical problems, the present invention provides the following technical solution: A base is included, a sliding plate is fixedly connected to the upper surface of the base, a movable seat is slidably connected inside the sliding plate, support plates are fixedly connected to both sides of the movable seat, a movable plate is movably connected to the upper surface of the support plate via a shaft, a sphere is movably connected to the rear surface of the movable plate, a connecting rod is fixedly connected to the rear surface of the sphere, a second fastening support ring is fixedly connected to the rear end of the connecting rod, fixed plates are fixedly connected to both sides of the second fastening support ring, a threaded rod passes through the interior of the fixed plate, a first fastening support ring is sleeved on the outer surface of the threaded rod, and the second fastening support ring is located above the first fastening support ring. Extrusion blocks are fixedly connected to the inner walls of both the first and second fastening support rings.

[0005] Preferably, a fixing rod is fitted inside the skateboard, and the rear end of the fixing rod passes through the interior of the movable seat.

[0006] Preferably, the front and rear ends of the fixing rod are both fitted with fastening fitting rods, and the outer surface of the fastening fitting rods is covered with rubber sleeves.

[0007] Preferably, a first fixing block is fixedly connected to the front end of the fastening fitting rod, a first spring is fixedly connected to the lower surface of the first fixing block, and a second fixing block is fixedly connected to the bottom end of the first spring.

[0008] Preferably, baffles are fixedly connected to both sides of the movable seat, and a handle is fixedly connected to the upper surface of the movable plate.

[0009] Preferably, the rear surface of the support plate is provided with a first connecting block, the rear surface of the first connecting block is provided with a rubber plate, the rear surface of the rubber plate is provided with a second connecting block, and the upper surface of the second connecting block is fixedly connected to the lower surface of the movable plate.

[0010] Preferably, the rear surface of the support plate is movably connected to a telescopic tube via a joint, and the telescopic tube is located below the movable plate. A slider is slidably connected inside the telescopic tube, and a sliding rod is fixedly connected to the lower surface of the slider. A metal block is movably connected to the rear end of the sliding rod via a ball, and a smoothing ring is fixedly connected to the rear surface of the metal block.

[0011] Preferably, the inner wall of the telescopic tube is provided with a rubber bladder, the rear surface of the rubber bladder is provided with a second spring, and the rear end of the second spring is fixedly connected to the front end of the slide rod.

[0012] Preferably, the lower surface of the base is provided with a brake wheel, and the upper surface of the base is provided with a groove.

[0013] Preferably, a screw block is fixedly connected to the bottom end of the threaded rod, and a nut is sleeved on the outer surface of the threaded rod, with the nut fitting against the front surface of the fixing plate.

[0014] Compared with the prior art, the present invention provides a multifunctional probe support frame for ultrasound-guided nerve block, which has the following advantages: 1. In this invention, after the ultrasound probe penetrates the interior of the first and second fastening support rings, tightening the screw block and nut continuously shortens the distance between the first and second fastening support rings. Through the continuous contraction of the first and second fastening support rings, the compression block can press against the surface of the ultrasound probe, thereby improving the fit between the first and second fastening support rings. After the ultrasound probe is fixed to the first and second fastening support rings, the connection between the sphere and the movable plate allows the probe to rotate and be positioned in multiple directions. The movable plate achieves pitch angle adjustment through the hinge structure between the shaft and the support plate. The rubber plate absorbs vibrations during operation through the first and second connecting blocks, preventing probe displacement, thereby improving the stability and accuracy of the ultrasound image during nerve block guidance.

[0015] 2. After the height of the support plate is adjusted, the fixed rod can be inserted through the interior of the slide plate and the movable seat. The fastening fitting rod is fitted into both ends of the fixed rod. The rubber sleeve can increase the friction when the fastening fitting rod and the fixed rod are fitted together, making it difficult for the fastening fitting rod to slide inside the fixed rod. After the fastening fitting rod and the fixed rod are fitted together, the weight at both ends of the fixed rod can be increased by the first fixed block and the second fixed block. The elasticity of the first spring can make the weight of the second fixed block pull the first spring, so that the weight at both ends of the fixed rod can be concentrated downward, thereby preventing the movable seat from displacing inside the slide plate.

[0016] 3. When the ultrasound probe is placed inside the first and second fastening support rings to detect and guide nerve block on a patient, the smoothing ring can fit against the surface of the ultrasound probe. Utilizing the elasticity of the second spring and the gas inside the rubber bladder, the smoothing ring can push the slide rod according to the movement of the ultrasound probe, allowing the slide rod to enter the telescopic tube and compress the second spring and the rubber bladder, thereby changing the movement of the ultrasound probe and reducing the shaking of the ultrasound probe during detection and guidance of nerve block.

[0019] 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.

[0020] Please see Figure 1-5A multifunctional probe support frame for ultrasound-guided nerve block includes a base 1. A slide plate 10 is fixedly connected to the upper surface of the base 1. A movable seat 3 is slidably connected inside the slide plate 10. Support plates 4 are fixedly connected to both sides of the movable seat 3. A movable plate 7 is movably connected to the upper surface of the support plate 4 via a shaft. A sphere 21 is movably connected to the rear surface of the movable plate 7. A connecting rod 14 is fixedly connected to the rear surface of the sphere 21. A second fastening support ring 18 is fixedly connected to the rear end of the connecting rod 14. Fixed plates 15 are fixedly connected to both sides of the second fastening support ring 18. A threaded rod 20 passes through the interior of the fixed plate 15. A first... A fastening support ring 17 is provided, and a second fastening support ring 18 is located above the first fastening support ring 17. The inner walls of both the first fastening support ring 17 and the second fastening support ring 18 are fixedly connected with compression blocks 23. A screwing block 16 is fixedly connected to the bottom end of the threaded rod 20. A nut 19 is sleeved on the outer surface of the threaded rod 20, and the nut 19 is in contact with the front surface of the fixed plate 15. A handle 6 is fixedly connected to the upper surface of the movable plate 7. A first connecting block 8 is provided on the rear surface of the support plate 4. A rubber plate 26 is provided on the rear surface of the first connecting block 8. A second connecting block 25 is provided on the rear surface of the rubber plate 26, and the upper surface of the second connecting block 25 is fixedly connected to the lower surface of the movable plate 7.

[0021] Different models of ultrasound probe handles are placed inside the first and second fastening support rings 17 and 18. The threaded rod 20 passes through both rings using the fixing plate 15, achieving initial fitting and pre-fixation to accommodate the basic placement requirements of different ultrasound probe models. By tightening the screw block 16 and nut 19, the distance between the first and second fastening support rings 17 and 18 can be flexibly shortened to accommodate the differences in the thickness of different ultrasound probe models. As the distance between the two rings decreases, the compression block 23 inside the rings will tightly compress against the surface of different ultrasound probe models. This compression force compensates for the differences in surface morphology of different ultrasound probes, enhancing the fit between the two rings and the probe. The fit of the ultrasound probe ensures stable fixation for different models of ultrasound probes, meeting the fixation requirements for ultrasound probes of different sizes and shapes. After the ultrasound probe is fixed with the first fastening support ring 17 and the second fastening support ring 18, the connection between the ball 21 and the movable plate 7 allows the probe to be rotated and positioned in multiple directions. The movable plate 7 achieves pitch angle adjustment through the hinge structure between the shaft and the support plate 4. The rubber plate 26 absorbs vibrations during operation through the first connecting block 8 and the second connecting block 25, preventing probe displacement, thereby improving the stability and accuracy of ultrasound images when guiding nerve blocks.

[0022] The sliding plate 10 is internally fitted with a fixing rod 9, and the rear end of the fixing rod 9 passes through the interior of the movable seat 3. The front and rear ends of the fixing rod 9 are both fitted with fastening fitting rods 29. The outer surface of the fastening fitting rod 29 is covered with a rubber sleeve 28. The front end of the fastening fitting rod 29 is fixedly connected to a first fixing block 27. The lower surface of the first fixing block 27 is fixedly connected to a first spring 31. The bottom end of the first spring 31 is fixedly connected to a second fixing block 30. Both sides of the movable seat 3 are fixedly connected with baffles 2.

[0023] After the height of the support plate 4 is adjusted, the fixing rod 9 can be passed through the interior of the slide plate 10 and the movable seat 3, and the fastening fitting rod 29 can be fitted into both ends of the fixing rod 9. The rubber sleeve 28 can increase the friction when the fastening fitting rod 29 and the fixing rod 9 are fitted, making it difficult for the fastening fitting rod 29 to slide inside the fixing rod 9. After the fastening fitting rod 29 and the fixing rod 9 are fitted, the weight at both ends of the fixing rod 9 can be increased by the first fixing block 27 and the second fixing block 30. The elasticity of the first spring 31 can pull the weight of the second fixing block 30 on the first spring 31, so that the weight at both ends of the fixing rod 9 can be concentrated downward, thereby preventing the movable seat 3 from displacing inside the slider 24.

[0024] The rear surface of the support plate 4 is movably connected to a telescopic tube 5 via a joint, and the telescopic tube 5 is located below the movable plate 7. A slider 24 is slidably connected inside the telescopic tube 5. A slide rod 22 is fixedly connected to the lower surface of the slider 24. A metal block 12 is movably connected to the rear end of the slide rod 22 via a ball. A smoothing ring 13 is fixedly connected to the rear surface of the metal block 12. A rubber bladder 32 is provided on the inner wall of the telescopic tube 5. A second spring 33 is provided on the rear surface of the rubber bladder 32, and the rear end of the second spring 33 is fixedly connected to the front end of the slide rod 22.

[0025] When the ultrasound probe is placed inside the first fastening support ring 17 and the second fastening support ring 18 to detect and guide nerve block on the patient, the smoothing ring 13 can fit against the surface of the ultrasound probe. Utilizing the elasticity of the second spring 33 and the gas inside the rubber bladder 32, the smoothing ring 13 can push the slide bar 22 according to the movement of the ultrasound probe, allowing the slide bar 22 to enter the telescopic tube 5 to compress the second spring 33 and the rubber bladder 32, thus smoothing the movement of the ultrasound probe and reducing the shaking of the ultrasound probe during detection and guidance of nerve block.

[0026] The lower surface of the base 1 is provided with a brake wheel 34, and the upper surface of the base 1 is provided with a groove 11.

[0027] When the device is in use, medical staff can step into the groove 11 to fix the base 1, and use the brake wheel 34 to push the device. The brake wheel 34 is fixed because the surface of the brake wheel 34 is provided with brake pads.

[0028] In use, the ultrasound probe is placed inside the first fastening support ring 17 and the second fastening support ring 18. The threaded rod 20 is inserted through the first fastening support ring 17 and the second fastening support ring 18 using the fixing plate 15, thus pre-fixing the ultrasound probe by fitting it into the first fastening support ring 17 and the second fastening support ring 18. After the ultrasound probe penetrates the first fastening support ring 17 and the second fastening support ring 18, tightening the screw block 16 and the nut 19 continuously shortens the distance between the first fastening support ring 17 and the second fastening support ring 18. This is achieved through the first fastening... As the support ring 17 and the second fastening support ring 18 continuously contract, the compression block 23 can press against the surface of the ultrasound probe, thereby improving the fit between the first fastening support ring 17 and the second fastening support ring 18. After the ultrasound probe is fixed to the first fastening support ring 17 and the second fastening support ring 18, the connection between the sphere 21 and the movable plate 7 allows the probe to be rotated and positioned in multiple directions. The movable plate 7 achieves pitch angle adjustment through the hinge structure between the shaft and the support plate 4. The rubber plate 26 absorbs the pressure through the first connecting block 8 and the second connecting block 25. To prevent probe displacement due to vibration during operation, a fixing rod 9 is inserted through the interior of the slide plate 10 and the movable seat 3. A fastening fitting rod 29 is fitted into both ends of the fixing rod 9. Rubber sleeves 28 increase the friction between the fastening fitting rod 29 and the fixing rod 9, preventing the fastening fitting rod 29 from sliding inside the fixing rod 9. After the fastening fitting rod 29 and the fixing rod 9 are fitted, the first fixing block 27 and the second fixing block 30 increase the weight at both ends of the fixing rod 9. The elasticity of the first spring 31 allows the weight of the second fixing block 30 to pull on the first spring 31, thus securing the two ends of the fixing rod 9. The weight of the end can be concentrated downwards. When the ultrasound probe is placed inside the first fastening support ring 17 and the second fastening support ring 18 to detect and guide nerve block, the smoothing ring 13 can fit against the surface of the ultrasound probe. Utilizing the elasticity of the second spring 33 and the gas in the rubber bladder 32, the smoothing ring 13 can push the slide bar 22 according to the movement of the ultrasound probe, allowing the slide bar 22 to enter the telescopic tube 5 to compress the second spring 33 and the rubber bladder 32, thus smoothing the movement of the ultrasound probe and reducing the shaking of the ultrasound probe during detection and guidance of nerve block.

[0029] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
