Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a nerve block device that enhances ultrasound-guided imaging. Background Technology

[0002] Nerve block devices are a combination of medical devices used to precisely locate and temporarily block the signal transmission of specific nerves. They are mainly used for intraoperative anesthesia, postoperative analgesia, and chronic pain management. In order to improve the accuracy and safety of ultrasound-guided nerve blocks, modern devices achieve dynamic visualization of nerve structures and operational optimization through multi-dimensional technological innovation.

[0003] For example, Chinese patent CN215018619U discloses a nerve block puncture device. By setting an auxiliary mechanism inside the handle, the spiral blade can drive the airflow inside the handle. The airflow can dissipate heat from the hands of medical personnel holding the outside of the handle, avoiding excessive sweating of the palms, and can also assist in cooling some of the liquid inside the needle, improving the puncture effect. By setting an adjustment mechanism, the toothed ring can drive the illumination lamp to rotate, and the light emitted by the illumination lamp can more accurately irradiate the surface of the puncture site, improving the visibility of the puncture site.

[0004] Existing nerve block devices require medical staff to manually puncture specific nerve sites and inject nerve-blocking agents. However, in practice, the medical staff need to control the puncture position and angle with their hands, which can lead to errors in the puncture location. Furthermore, during the injection of the nerve-blocking agent, the shaking of the medical staff's hands can not only cause deviations in the injection location, but also pose a risk of nerve damage due to the movement of the puncture tool inside the patient's body, thus presenting certain safety hazards during the operation. Summary of the Invention

[0005] To address the problem of inaccurate injection location of nerve blockers in existing technologies, this invention utilizes a guide groove to accurately adjust and control the puncture angle of the puncture tube, thereby enabling precise injection of nerve blockers to the appropriate site under ultrasound guidance. Simultaneously, the guide frame stabilizes the position of the puncture tube. The purpose of this invention is to provide a nerve blocker device that enhances effective ultrasound-guided imaging.

[0012] Optionally, an expansion assembly is provided between the slide rod and the baffle. The expansion assembly includes an embedded mounting groove on the outer surface of the slide rod. A bladder is fixedly connected to the inner surface of the mounting groove away from the baffle. A contact plate is fixedly connected to the outer surface of the bladder near the baffle. Both the outer surfaces of the bladder and the contact plate are annular.

[0013] Optionally, an air guide groove 1 is embedded in the inner side of the slide rod, and an air guide groove 2 is embedded in the inner side of the clamping plate.

[0017] Compared with the prior art, the technical solution provided by this invention has at least the following beneficial effects:

[0018] In the above scheme, by setting the adjustment component, not only can the puncture angle of the puncture tube be accurately adjusted and controlled, so that the nerve blocking agent can be accurately injected into the appropriate site under ultrasound guidance, but the guide frame can also keep the position of the puncture tube stable, which helps to reduce the puncture error caused by the hand movement of medical staff during the puncture process, and keep the puncture depth within an appropriate range, thereby further improving the puncture accuracy and effectively ensuring the nerve blocking effect.

[0019] By setting a limiting component, the squeezing force between the squeezing block and the guide groove can play a certain limiting role on the slide rod, thereby fixing the slide rod to the outside of the guide frame. By setting a limiting component, the slide rod can be limited and fixed at different positions in the guide groove, which can not only improve the stability of the blocking agent during the injection process, but also effectively reduce the probability of the slide rod accidentally sliding, thereby further improving the treatment accuracy.

[0020] By setting up an expansion component, the second capsule will cause the friction plate to adhere to the outer surface of the injection tube. The friction between the friction plate and the injection tube can further improve the clamping effect of the clamp on the injection tube, thereby keeping the position of the injection tube stable. This helps to further reduce the probability of the injection tube shifting during the injection of the nerve blocker, and thus effectively improves the safety of the nerve blocker during operation.

[0021] By setting up the adhesion component, a certain negative pressure will be created between the suction cup and the patient's skin, thus allowing the suction cup to be stably attached to the patient's skin surface. The suction cup fixes and supports the guide frame, which can further improve the placement stability of the guide frame. The swing arm will drive the extrusion wheel to roll and press the upper surface of the film, which helps to accelerate the expulsion of air between the film and the skin, thereby making the film adhere more tightly to the patient's skin. By improving the sealing effect between the suction cup and the skin, the adhesion stability of the suction cup can be further improved. Attached Figure Description

[0038] like Figures 1 to 7 As shown, this embodiment of the invention provides a nerve block device for enhanced ultrasound-guided imaging, including a fixing sleeve 13. A frame 11 is engaged with the inner surface of the fixing sleeve 13. A probe 12 is fixedly connected to the outer surface of the lower end of the frame 11. An adjustment assembly is provided on the outer side of the fixing sleeve 13. The adjustment assembly includes a mounting plate 15 fixedly connected to the outer surface of the fixing sleeve 13. A guide frame 16 is detachably connected to the inner side of the mounting plate 15. A guide groove 17 is formed through the outer surface of the guide frame 16. A slide rod 27 is damped and slidably connected to the inner side of the guide groove 17. A sleeve 19 is fixedly connected to the outer surface of the slide rod 27. A clamping plate 25 is fixedly connected to the outer surface of the sleeve 19. An injection tube 20 is engaged with the inner side of the clamping plate 25. A puncture tube 21 is fixedly connected to the lower end of the injection tube 20. A squeezing rod 22 is slidably connected to the inner side of the injection tube 20.

[0039] Both the guide frame 16 and the guide groove 17 are arc-shaped. The clamping plate 25 has a C-shaped structure and is made of elastic material. The data cable 14 is fixedly connected to the upper outer surface of the frame 11. The rear end of the sleeve 19 slides in contact with the front outer surface of the guide frame 16. The injection tube 20 is made of transparent material. The outer surface of the injection tube 20 has scale lines. The outer surface of the guide frame 16 has angle lines.

[0040] By adopting the above technical solution, when using the nerve block device, the ultrasound probe 12 is placed on the patient's body surface via the frame 11. The enhanced ultrasound probe 12 scans and visualizes the surrounding nerves. Then, the fixing sleeve 13 is fitted onto the outside of the frame 11, and the guide frame 16 is snapped into the mounting plate 15 on the surface of the fixing sleeve 13, thereby achieving rapid assembly of the guide frame 16. After the guide frame 16 is installed, according to the nerve position scanned by the probe 12, the slide rod 27 slides along the inside of the guide groove 17. The slide rod 27 and the guide groove 17 are connected by damped sliding. Under no external force, the friction between the slide rod 27 and the guide groove 17 keeps the slide rod 27 relatively stable. During the movement of the slide rod 27, it drives the sleeve 19 to move synchronously. The sleeve 19 clamps and fixes the injection tube 20 through the clamp 25, thereby keeping the position between the injection tube 20 and the slide rod 27 relatively stable. The guide groove 17 is arc-shaped. During the sliding of the slide rod 27 inside the guide groove 17, the position between the injection tube 20 and the probe 12 is relatively stable. The angle will also change accordingly. The deflection angle can be directly observed through the angle lines on the surface of the guide frame 16. After the injection tube 20 moves the puncture tube 21 to the appropriate angle, the operator slides the injection tube 20 along the inner side of the clamp 25, so that the injection tube 20 moves the puncture tube 21 into the patient's limb. After the puncture tube 21 is inserted into the appropriate position, the operator installs the squeezing rod 22. Through the squeezing rod 22, the nerve blocking agent inside the injection tube 20 can be injected from the puncture tube 21 into the patient's body, thereby achieving precise nerve block. By setting the adjustment component, not only can the puncture angle of the puncture tube 21 be accurately adjusted and controlled, so that the nerve blocking agent can be accurately injected into the appropriate site under ultrasound guidance, but the guide frame 16 can also keep the position of the puncture tube 21 stable, which helps to reduce the puncture error caused by the movement of the medical staff's hands during the puncture process, and keep the puncture depth within the appropriate range, thereby further improving the puncture accuracy and effectively ensuring the nerve block effect.

[0041] like Figures 4 to 6 As shown, a limiting component is provided on the inner side of the slide rod 27. The limiting component includes a storage groove 40 embedded in the inner side of the slide rod 27. A push rod 28 is threadedly connected to the inner side of the storage groove 40. A guide seat 42 is fixedly connected to the inner surface of the storage groove 40. A slot 44 is provided through the outer surface of the slide rod 27. The slot 44 is connected to the inside of the storage groove 40. A pressing block 41 is slidably connected to the inner side of the slot 44.

[0042] The outer surface of the guide seat 42 is conical, and the outer surface of the extrusion block 41 is in sliding contact with the guide seat 42. The number of slots 44 and extrusion blocks 41 are several groups and arranged in a ring array. The side of the extrusion block 41 away from the guide seat 42 is in contact with the inner wall of the guide groove 17. The inner surface of the receiving groove 40 is slidably connected to a movable block 38, and the outer surface of the movable block 38 is in sliding contact with the extrusion block 41.

[0043] A spring 43 is fixedly connected to the outer surface of the movable block 38. The spring 43 is sleeved on the outside of the guide seat 42. A top sleeve 39 is fixedly connected to the outer surface of the movable block 38 away from the spring 43. The top sleeve 39 is in rotatable contact with the outer surface of the push rod 28. A baffle 26 is fixedly connected to the end of the push rod 28 away from the top sleeve 39. The pressing block 41 is made of elastic wear-resistant material.

[0044] By adopting the above technical solution, in order to further improve the puncture stability, a limiting component is set. When the slide bar 27 moves to the appropriate position, the operator turns the push bar 28 through the baffle 26. The push bar 28 is threadedly connected to the receiving groove 40. During the rotation, it slides into the receiving groove 40. During the movement, the push bar 28 drives the movable block 38 to slide linearly along the inside of the receiving groove 40. The movable block 38 pushes the extrusion block 41 through the top sleeve 39. The groove 44 can play a certain limiting role for the extrusion block 41. During the movement, the extrusion block 41 will slide into contact with the outer surface of the guide seat 42. The outer surface of the guide seat 42 is conical. Under the guidance of the guide seat 42, the extrusion block 41 will extend outward along the inside of the groove 44. After the extrusion block 41 moves a certain distance outward from the slide bar 27, its outer surface will contact the guide groove. The internal contact between the squeezing block 41 and the guide groove 17 can limit the sliding rod 27, thereby fixing the sliding rod 27 to the outside of the guide frame 16. By setting the limiting component, the sliding rod 27 can be limited and fixed at different positions in the guide groove 17. This not only improves the stability of the blocking agent during injection, but also effectively reduces the probability of the sliding rod 27 sliding accidentally, thereby further improving the treatment accuracy. When the movable block 38 is pushed by the squeezing block 41 through the top sleeve 39, the squeezing block 41, together with the storage groove 40, will squeeze the spring 43. When adjusting the position of the sliding rod 27, the operator rotates the push rod 28 in the opposite direction. At this time, the squeezing block 41 will move in the opposite direction under the elastic force of the spring 43, thereby disengaging the squeezing block 41 from the inner wall of the guide groove 17.

[0045] like Figure 4 and Figure 5As shown, an expansion assembly is provided between the slide rod 27 and the baffle 26. The expansion assembly includes an embedded mounting groove 31 on the outer surface of the slide rod 27. A bladder 32 is fixedly connected to the inner surface of the mounting groove 31 away from the baffle 26. A contact plate 33 is fixedly connected to the outer surface of the bladder 32 near the baffle 26. The outer surfaces of both the bladder 32 and the contact plate 33 are annular.

[0046] The inner side of the slide bar 27 is provided with an air guide groove 30, and the inner side of the clamping plate 25 is provided with an air guide groove 34. One end of the air guide groove 30 extends into the interior of the first bladder 32, and the other end is connected to the interior of the second air guide groove 34. The second bladder 36 is fixedly connected to the inner surface of the clamping plate 25. The end of the second air guide groove 34 away from the air guide groove 30 is connected to the interior of the second bladder 36.

[0047] A friction plate 37 is fixedly connected to the outer surface of the second capsule 36. The outer surface of the friction plate 37 away from the second capsule 36 is in contact with the outer surface of the injection tube 20. There are two sets of second capsules 36, which are symmetrically distributed on both sides of the injection tube 20. The outer surface of the second capsule 36 is arc-shaped. A guide strip 35 is fixedly connected to the inner surface of the clamp 25. The outer surface of the guide strip 35 is in sliding contact with the injection tube 20.

[0048] By adopting the above technical solution, after the slide bar 27 moves to the appropriate position, the operator pushes the injection tube 20 along the inner side of the clamp 25. The clamp 25, together with the guide strip 35, can play a certain limiting role for the injection tube 20, so that the injection tube 20 can slide linearly and accurately puncture into the patient's body. When the slide bar 27 is fixed and limited, when the baffle 26 moves to one side of the slide bar 27, the slide bar 27 will come into contact with the outer surface of the contact plate 33 and squeeze the contact plate 33. The slide bar 27 is fixedly installed on the capsule 32 through the mounting groove 31, and the baffle 26 drives the contact plate 33 to press against the capsule 32. When compressed, the gas inside the first capsule 32 enters the second capsule 36 through the first gas guide groove 30 and the second gas guide groove 34. The second capsule 36 gradually inflates and expands. At this time, the second capsule 36 drives the friction plate 37 to adhere to the outer surface of the injection tube 20. The friction between the friction plate 37 and the injection tube 20 can further improve the clamping effect of the clamping plate 25 on the injection tube 20, thereby keeping the position of the injection tube 20 stable. This helps to further reduce the probability of the injection tube 20 shifting during the injection of the nerve blocking agent, and thus effectively improves the safety of the nerve blocking device during operation.

[0049] Such as 1 and Figure 7As shown, a bonding component is provided on the lower side of the guide frame 16. The bonding component includes a suction cup 23 fixedly connected to the lower outer surface of the guide frame 16. A guide tube 24 is fixedly connected to the upper outer surface of the suction cup 23. A control valve 45 is fixedly connected to the inner surface of the guide tube 24. A folding groove 18 is embedded in the outer surface of the suction cup 23. The number of folding grooves 18 is several groups and they are distributed in a parallel array.

[0050] The suction cup 23 is made of elastic material. An ear seat 47 is fixedly connected to the upper side of the inner surface of the suction cup 23. A pin 29 is fixedly connected to the outer surface of the ear seat 47. A swing arm 49 is rotatably connected to the outer surface of the pin 29. A second pin 48 is fixedly connected to the end of the swing arm 49 away from the first pin 29. A pressing wheel 50 is rotatably connected to the outer surface of the second pin 48. A film 46 is fixedly connected to the lower side of the inner surface of the suction cup 23. The film 46 is annular. The lower side of the outer surface of the pressing wheel 50 slides in contact with the film 46. The pressing wheel 50 consists of several groups and is distributed in a ring array.

[0051] By adopting the above technical solution, when the probe 12 is placed on the patient's body surface, the suction cup 23 is simultaneously placed on the patient's outer body surface. The film 46 will adhere to the outer side of the patient's skin. Then, the patient presses the suction cup 23 to expel the air inside the suction cup 23 through the conduit 24 and the control valve 45. At this time, a certain negative pressure will appear between the suction cup 23 and the patient's skin, so that the suction cup 23 is stably attached to the patient's skin surface. The suction cup 23 fixes and supports the guide frame 16, which can further improve the placement stability of the guide frame 16. The folded groove 18 on the surface of the suction cup 23 can reduce the deformation resistance of the suction cup 23 to a certain extent, so that the suction cup 23 can better adapt to the skin surface. Due to the curvature change of the surface, the suction cup 23 is fixed and supported by the ear seat 47 and the pin 29. The pin 29 is supported by the swing arm 49 and the second pin 48. The second pin 48 is used to support the rotation of the extrusion wheel 50. When the suction cup 23 is pressed down, the suction cup 23 will undergo elastic deformation and its thickness will decrease. At this time, the angle between the swing arm 49 and the horizontal direction will gradually increase. The swing arm 49 will drive the extrusion wheel 50 to roll and press the upper surface of the film 46, which helps to accelerate the expulsion of air between the film 46 and the skin, thereby enabling the film 46 to adhere more tightly to the patient's skin. By improving the sealing effect between the suction cup 23 and the skin, the adsorption stability of the suction cup 23 can be further improved.

[0052] The workflow of the technical solution of this invention is as follows:

[0053] When using the nerve block device, the ultrasound probe 12, carried by the frame 11, is placed on the patient's body surface. The enhanced ultrasound probe 12 scans and visualizes the surrounding nerves. Then, the suction cup 23 is simultaneously placed on the patient's outer surface, and the film 46 adheres to the patient's skin. Simultaneously, the swing arm 49 drives the compression wheel 50 to roll and press the upper surface of the film 46, helping to accelerate the expulsion of air between the film 46 and the skin, thus ensuring a tighter fit. Based on the nerve location scanned by the probe 12, the slide bar 27 slides along the guide groove 17. As the slide bar 27 slides within the guide groove 17, the angle between the injection tube 20 and the probe 12 changes accordingly. Once the injection tube 20 moves the puncture tube 21 to the appropriate angle, the operator pushes the injection tube 20 along the inner side of the clamp 25. The clamp 25, in conjunction with the guide bar 35, provides support for the injection tube 20. A certain limiting effect allows the injection tube 20 to slide linearly and accurately puncture the patient's body. During the movement of the push rod 28, the movable block 38 will slide linearly along the inside of the receiving groove 40. The movable block 38 pushes the squeezing block 41 through the top sleeve 39. Under the guidance of the guide seat 42, the squeezing block 41 will extend outward along the inside of the groove 44. The squeezing force between the squeezing block 41 and the guide groove 17 can play a certain limiting role on the slide rod 27, thereby fixing the slide rod 27 to the outside of the guide frame 16. The baffle 26 drives the contact plate 33 to squeeze the first capsule 32. The gas inside the first capsule 32 will enter the second capsule 36 through the first gas guide groove 30 and the second gas guide groove 34. The second capsule 36 will drive the friction plate 37 to adhere to the outer surface of the injection tube 20. The friction between the friction plate 37 and the injection tube 20 can further improve the clamping effect of the clamp 25 on the injection tube 20.
