[0001] The present invention relates to the technical field of hydro - acupuncture needles, and particularly to a graduated hydro - acupuncture needle with enhanced ultrasonic imaging effect. Background Technique

[0002] The hydro - acupuncture needle is a medical device that combines an acupuncture needle, a small needle knife, and an injection needle. It is developed on the basis of the traditional small needle knife, integrating the characteristics of acupuncture and small needle knife techniques, and can perform drug injection. The hydro - acupuncture needle belongs to a type of surgical cutting instrument. Its front end has a small needle - knife part, similar to a small needle knife, which can perform operations such as cutting and peeling on diseased tissues. However, it is different from traditional surgical cutting instruments because it also has an injection function. While performing operations such as cutting, it can inject drugs around the diseased area to enhance the treatment effect.

[0003] In the prior art, during the use of the hydro - acupuncture needle, it is necessary to hold the needle handle part and then push the hydro - acupuncture needle forcefully to connect it with the plug of the syringe. During the process of pinching the needle handle, it is very easy to slip, resulting in the fingers of medical staff slipping off the needle handle, increasing the risk of accidents such as needle - stick injuries. If accidentally colliding with the syringe, it will also cause finger pain or injury, which is not conducive to the normal progress of subsequent work.

[0004] Therefore, we propose a graduated hydro - acupuncture needle with enhanced ultrasonic imaging effect to solve the problems raised in the above - mentioned background technique. Summary of the Invention

[0010] Preferably, the two ends of the two central shafts are respectively fixedly installed on both sides inside the two storage grooves near the fixing blocks, and the two ends of the two limiting rods are respectively fixedly installed on both sides inside the two storage grooves near the fixing rods.

[0011] Preferably, on one side outer surface of each of the two metal sheets, they are respectively fixedly installed on one side outer surface of the two auxiliary clips. The inner parts of the four outer tooth rubber rings are respectively fixedly connected to the outer surfaces of the two fixing rods near both ends.

[0012] Preferably, one end of each of the two return springs is respectively fixedly connected to the bottom of the two movable plates, and the other end of each of the two return springs is respectively fixedly connected to the inner walls of the two fixing blocks. One end of each of the two ejector rods respectively movably penetrates to the top of the two fixing blocks, and the outer surfaces of the two auxiliary clips are respectively in contact with the outer surfaces of the two fixing blocks near the movable holes.

[0013] Preferably, the enhancement component includes a needle body. On the outer surface of the needle body, there are provided scale marks.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When the present invention is used, the adjusting gear is rotated to drive the limit gear to rotate, and the limit plate is driven to rotate at the same time, so that the magnet is separated from the metal sheet. When the limit plate rotates to the top of the limit gear, the adjusting gear is stopped. At the same time, the two arc plates are pressed to push the two push rods to move relative to each other, so that one end of each of the two push rods passes through the two movable holes to push one side of the auxiliary clip to rotate inside the storage slot. Under the limit of the central axis, the other side of the auxiliary clip is rotated out of the storage slot. At this time, the two auxiliary clips are unfolded in an airfoil shape, and the pressure on the two arc plates is released. The medical staff clamps the needle handle body between the index finger and the middle finger, so that the index finger and the middle finger are respectively located at the two storage slots, and are against the two unfolded auxiliary clips. The auxiliary clip unfolded in an airfoil shape provides a force support point, which reduces the dependence on the pinching force of the needle handle body, and is more stable during operation, avoiding slipping, causing the needle handle to slip off. Under the action of the auxiliary component, the finger is prevented from slipping off and accidentally colliding with the syringe, causing finger pain, and the safety is higher.

[0019] 2. When the present invention is used, the scale markings facilitate the doctor to accurately control the depth of the water needle knife entering the tissue and perform standardized operations according to the scale. The metal layer is made of medical stainless steel and is the main structure of the water needle knife, providing support and puncture rigidity. The nanoscale ultrasonic development coating can improve the reflected signal of the ultrasonic wave, improve the clarity and contrast of ultrasonic imaging, and enhance the development effect of the water needle knife in the ultrasonic image. The protective layer provides mechanical protection and increases the durability of the needle body. The inner layer of the injection channel is used to guide the drug from the external syringe through the injection hole to be accurately injected into the surrounding area of ​​the diseased tissue. The anti-adhesion coating can reduce the resistance of the drug when passing through the injection hole, and the drug will not adhere to the inner wall of the injection hole, reducing the possibility of drug residue.

[0020] 3. When the present invention is used, when the ultrasonic wave encounters a micro-metal reflective ball, a strong reflection will occur, allowing the doctor to easily identify the position of the needle blade head. The micro-metal reflective balls set at a certain distance form a series of bright spots. These bright spots are distributed along the needle body, like a "signal chain". The doctor observes the position and arrangement of these bright spots to accurately judge the direction of the needle body and the depth of the needle blade head, thereby achieving precise positioning. The micro-metal reflective balls in the enhancement plate are distributed in a circle, which can provide more comprehensive information on the position of the needle body, and make up for the defect that a single reflective ball may have unclear signals due to angle problems. The formed signal is more continuous on the ultrasonic image, which is more helpful for doctors to accurately judge the position and direction of the needle body, greatly improving the ultrasonic imaging effect.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Example 1: Please refer to Figures 1 - 10As shown in the figure, the present invention provides a technical solution: a graduated water acupuncture knife for enhancing ultrasonic imaging effect, which includes a needle handle body 1.

Auxiliary clips 302 are movably sleeved on the outer surfaces of the two central shafts 301. Fixed rods 303 are fixedly installed inside the two storage grooves 4. Limiting gears 304 are movably sleeved on the outer surfaces of the two fixed rods 303. Adjusting gears 305 are meshed with the outer surfaces of the two limiting gears 304. Limiting rods 306 are movably embedded inside the two adjusting gears 305. Limiting plates 307 are fixedly installed on the outer surfaces of the two adjusting gears 305. Magnets 308 are fixedly installed on the outer surfaces of one side of the two limiting plates 307. Metal sheets 309 are magnetically connected to the bottoms of the two magnets 308. Fastening rings 310 are fixedly installed on the outer surfaces of both sides of the two limiting gears 304. Inner tooth rubber rings 311 are fixedly connected to the inner walls of the four fastening rings 310. Outer tooth rubber rings 312 are meshed with the interiors of the four inner tooth rubber rings 311. A plurality of ball grooves 313 are opened on the outer surfaces of one side of the four fastening rings 310. Ball bearings 314 are fixedly installed inside the plurality of ball grooves 313. Fixed blocks 315 are fixedly installed inside the two storage grooves 4 away from the fixed rods 303. Movable plates 316 are movably embedded inside the two fixed blocks 315. Thrust rods 317 are movably embedded inside the two movable plates 316. Return springs 318 are movably sleeved on the outer surfaces of the two thrust rods 317. Arc-shaped plates 319 are fixedly installed at one ends of the two thrust rods 317. Movable holes 320 are opened on the outer surfaces of the two fixed blocks 315. The two ends of the two central shafts 301 are respectively fixedly installed on both sides of the two storage grooves 4 close to the fixed blocks 315. The two ends of the two limiting rods 306 are respectively fixedly installed on both sides of the two storage grooves 4 close to the fixed rods 303. The outer surfaces of one side of the two metal sheets 309 are respectively fixedly installed on the outer surfaces of one side of the two auxiliary clips 302. The interiors of the four outer tooth rubber rings 312 are respectively fixedly connected to the outer surfaces of the two fixed rods 303 close to both ends. The plurality of ball bearings 314 distributed in a circle for each group of the plurality of ball bearings 314. The outer surfaces of the four groups of ball bearings 314 are respectively in contact with both sides inside the two storage grooves 4. One ends of the two return springs 318 are respectively fixedly connected to the bottoms of the two movable plates 316. The other ends of the two return springs 318 are respectively fixedly connected to the inner walls of the two fixed blocks 315. One ends of the two thrust rods 317 respectively movably penetrate through the tops of the two fixed blocks 315. The outer surfaces of the two auxiliary clips 302 are respectively in contact with the outer surfaces of the two fixed blocks 315 close to the movable holes 320.

[0035] In this embodiment, when in use, the adjusting gear 305 is rotated to drive the limiting gear 304 to rotate, and at the same time, the limiting plate 307 is driven to rotate upward with the limiting rod 306 as the center, and the magnet 308 is driven to rotate together, so that the magnet 308 is separated from the metal sheet 309. When the limiting gear 304 rotates, the two fastening rings 310 are driven to rotate, so that the two inner-toothed rubber rings 311 rotate on the outer surfaces of the corresponding outer-toothed rubber rings 312. When the limiting plate 307 rotates to the top of the limiting gear 304, the adjusting gear 305 stops rotating. At this time, the fastening ring 310 and the limiting gear 304 are limited by the cooperation of the inner-toothed rubber ring 311 and the outer-toothed rubber ring 312, so that the rotating adjusting gear 305 and the limiting plate 307 are limited, so as to prevent the limiting gear 304 from rotating by itself and affecting the rotation state of the adjusting gear 305 and the limiting plate 307. Then, the two arc plates 319 are pressed at the same time, pushing the two push rods 317 to move relative to each other, and driving the two movable plates 316 to move in the corresponding fixed blocks 315, so that the reset spring 318 is squeezed and contracted together, and one end of the two push rods 317 passes through the two movable holes 320 respectively, and contacts the two auxiliary clamps 302. As the push rod 317 continues to move, one side of the auxiliary clamp 302 is pushed to rotate toward the inside of the storage groove 4. Under the limitation of the central axis 301, the other side of the auxiliary clamp 302 is turned out from the storage groove 4. At this time, the two auxiliary clamps 302 are unfolded in a wing shape, and the pressure on the two arc plates 319 is released. The reset spring 318 pushes the push rod 317 and the arc plate 319 to reset. At this time, the two auxiliary clamps 302 are in an open state. The medical staff clamps the needle handle body 1 between the index finger and the middle finger, and makes the index finger and the middle finger respectively resist the two auxiliary clamps 302. The two auxiliary clamps 302 provide a force support point, reduce the dependence on the pinching force of the needle handle body 1, and make the operation more stable, avoid slipping, and cause the needle handle to slip off. Under the action of the auxiliary component 3, the fingers are prevented from slipping and accidentally colliding with the syringe, causing finger pain. It is safer and solves the problem of pinching the needle handle to connect the water needle knife to the syringe during use. In the process of pinching the needle handle, it is easy to slip, causing the finger to slip off the needle handle, increasing the risk of accidents such as needle sticks. If it collides with the syringe, it will also cause finger pain or injury. After connecting the syringe to the syringe jack connector 5, the two auxiliary clips 302 are rotated back into the receiving slot 4, and then the limiting plate 307 is rotated in the opposite direction so that the magnet 308 is magnetically attracted to the metal sheet 309 again. With the cooperation of the fixing block 315, the auxiliary clip 302 is limited so that it is stored in the receiving slot 4 to avoid affecting the subsequent use of the water needle knife.

[0036] Embodiment 2: Figures 1 - 5As shown, the enhancement component 2 includes a needle body 201, the outer surface of the needle body 201 is provided with a scale mark 202, one end of the needle body 201 is fixedly connected to a needle cutter head 203, the interior of the needle body 201 is provided with a first injection hole 204, the interior of the needle cutter head 203 is provided with a second injection hole 205, the interior of the needle body 201 is provided with an enhancement cavity 206, the interior of the enhancement cavity 206 is fixedly installed with a plurality of enhancement plates 207, the outer surfaces of the plurality of enhancement plates 207 are provided with a plurality of mounting holes 208, the interiors of the plurality of mounting holes 208 are fixedly installed with miniature metal reflective balls 209, one end of the needle body 201 is connected to the needle body 201, and the second injection hole 205 is provided with a second injection hole 205. One end of the needle handle body 1 is fixedly connected, and the other end of the needle handle body 1 is fixedly connected to the syringe jack connector 5. An injection cavity 6 is opened inside the needle handle body 1. The first injection hole 204, the second injection hole 205, the injection cavity 6 and the interior of the syringe jack connector 5 are connected. The needle body 201 includes a metal layer 2011, an ultrasonic development coating 2012 is arranged on the top of the metal layer 2011, a protective layer 2013 is arranged on the top of the ultrasonic development coating 2012, an injection channel inner layer 2014 is arranged on the bottom of the metal layer 2011, and an anti-adhesion coating 2015 is arranged on the bottom of the injection channel inner layer 2014.

[0037] In this embodiment, when in use, the outer surface of the needle body 201 is provided with a scale mark 202, which allows the doctor to accurately control the depth of the water needle knife entering the tissue, avoid damaging important nerves, blood vessels or internal organs due to too deep needle insertion, and prevent the needle from being inserted too shallowly and failing to achieve the treatment effect. Different doctors can perform standardized operations according to the scale during operation, which is convenient for recording and communicating the treatment process, and helps to achieve standardization of the treatment process. The metal layer 2011 is made of medical stainless steel and is the main structure of the water needle knife, providing support and rigidity for puncture. Medical stainless steel has good strength, toughness and corrosion resistance. High strength enables it to withstand the pressure during puncture, toughness ensures that it is not easy to break when bent at a certain angle, and corrosion resistance prevents rusting due to contact with human tissue fluid during use, ensuring the safety of the water needle knife. The outer surface of the metal layer 2011 is coated with a nano-scale ultrasonic development coating 2012, which is a mixture of metal oxide microparticles and high molecular polymers. The nano-scale coating thickness can ensure effective reflection of ultrasonic signals without significantly increasing the diameter of the needle body 201, affecting the puncture operation. The metal oxide microparticles can efficiently reflect ultrasonic signals, while the high molecular polymer plays a role in bonding and protecting the microparticles, ensuring the stability and durability of the coating, so that the development effect can be maintained well during multiple uses. The ultrasonic development coating 2012 can improve the reflected signal of the ultrasonic wave, improve the clarity and contrast of ultrasonic imaging, and enhance the development effect of the water needle knife in the ultrasonic image. When the ultrasonic signal encounters the coating, due to the large difference in the acoustic properties of the coating and the surrounding tissue, the ultrasonic signal will be reflected at the interface between the two, allowing the doctor to more clearly observe the position of the needle body 201 in the human tissue, facilitating precise operation. The protective layer 2013 is made of high-strength plastic material to provide mechanical protection to prevent external damage, increase the durability of the needle body 201, and provide a smooth outer surface. The injection channel inner layer 2014 is made of the same medical stainless steel material as the metal layer 2011, ensuring integration and sealing with the metal layer 2011, and is used to guide the drug from the external syringe through the injection hole to accurately inject around the diseased tissue. The anti-adhesion coating 2015 uses polytetrafluoroethylene coating. Polytetrafluoroethylene has an extremely low friction coefficient and extremely stable chemical properties. It hardly reacts with any chemical substances. It also has good corrosion resistance and non-stick properties. Its extremely low friction coefficient can greatly reduce the resistance of the drug when it passes through the injection hole, ensuring that the drug can be smoothly injected into the lesion site at a stable flow rate and flow rate. The non-stick property prevents the drug from adhering to the inner wall of the injection hole, reducing the possibility of drug residue. This not only ensures the accuracy of each injection dose, but also prevents the residual drug from drying and deteriorating in the injection hole. Figure 2As shown, a plurality of enhancement plates 207 are arranged inside the enhancement cavity 206, and miniature metal reflection balls 209 are arranged at certain intervals. The acoustic impedance of the miniature metal reflection balls 209 is much higher than that of human tissue. When ultrasonic waves encounter the miniature metal reflection balls 209, strong reflection will occur. This reflected signal appears as a bright spot in the ultrasonic image, which is in sharp contrast with the echo of the surrounding tissue, allowing the doctor to easily identify the position of the needle blade head 203. The miniature metal reflection balls 209 are inlaid at certain intervals, and the multiple miniature metal reflection balls 209 form a series of bright spots. These bright spots are distributed along the needle body 201 like a "signal chain". The doctor can accurately judge the direction of the needle body 201 and the depth of the needle blade head 203 by observing the position and arrangement of these bright spots, thereby achieving precise positioning, avoiding unnecessary damage to the surrounding normal tissues, and improving the treatment effect. The miniature metal reflection balls 209 in each enhancement plate 207 are distributed in a circle, such as Figure 4 As shown, in ultrasound imaging, the circumferentially distributed micro-metal reflective balls 209 can reflect ultrasound in all directions, providing more comprehensive information on the position of the needle 201, making up for the defect that a single reflective ball may have unclear signals due to angle problems. In addition, the signal formed by a circle of multiple micro-metal reflective balls 209 is more continuous on the ultrasound image, which is more helpful for doctors to accurately determine the position and direction of the needle 201, especially when the needle 201 needs to perform complex operations such as rotation and tilting, it can provide more complete information, and under the action of the enhancement component 2, the ultrasound imaging effect is improved.

[0038] The effect and working principle of the whole mechanism are as follows: when in use, the adjusting gear 305 is rotated to drive the limiting gear 304 to rotate, and at the same time, the limiting plate 307 is driven to rotate, so that the magnet 308 is separated from the metal sheet 309. When the limiting plate 307 rotates to the upper part of the limiting gear 304, the adjusting gear 305 stops rotating, and at this time, the fastening ring 310 and the limiting gear 304 are limited by the cooperation of the inner tooth rubber ring 311 and the outer tooth rubber ring 312, thereby limiting the rotating adjusting gear 305 and the limiting plate 307. Then, the two arc plates 319 are pressed at the same time, the two push rods 317 are pushed to move relative to each other, and the two movable plates 316 are driven to squeeze the two reset springs 318, and one end of the two push rods 317 pushes one side of the two auxiliary clamps 302 to rotate inside the two storage slots 4, and under the limit of the central axis 301, the other side of the auxiliary clamp 302 is turned out from the storage slot 4, and the pressure on the two arc plates 319 is released, and the two auxiliary clamps 302 are in an open state. The medical staff clamps the needle handle body 1 between the index finger and the middle finger, and makes the index finger and the middle finger respectively against the two auxiliary clamps 302, and provides a force support point through the two auxiliary clamps 302, reducing the dependence on the pinching force of the needle handle body 1, making the operation more stable, avoiding slipping, and having higher safety. After the syringe is connected to the syringe jack connector 5, the two auxiliary clips 302 are rotated and returned to the receiving slot 4, and then the limiting plate 307 is rotated in the opposite direction so that the magnet 308 is magnetically attracted to the metal sheet 309 again. With the cooperation of the fixing block 315, the auxiliary clip 302 is limited so that it is stored in the receiving slot 4. The scale mark 202 allows the doctor to accurately control the depth of the water needle knife entering the tissue, which helps to achieve the standardization of the treatment process. The metal layer 2011 is made of medical stainless steel and is the main structure of the water needle knife, providing support and puncture rigidity. The nano-scale ultrasonic development coating 2012 is a mixture of metal oxide microparticles and high molecular polymers, which can improve the reflected signal of the ultrasonic wave, improve the clarity and contrast of ultrasonic imaging, and enhance the development effect of the water needle knife in the ultrasonic image. The protective layer 2013 provides mechanical protection and a smooth outer surface. The injection channel inner layer 2014 is made of the same medical stainless steel as the metal layer 2011. The anti-adhesion coating 2015 uses polytetrafluoroethylene coating, which has extremely low friction coefficient, corrosion resistance and non-stickiness, reducing the resistance of the drug when passing through the injection hole, and the non-stickiness prevents the drug from adhering to the inner wall of the injection hole. Figure 2As shown, multiple enhancement plates 207 are arranged inside the enhancement cavity 206, and miniature metal reflective balls 209 are arranged at intervals. When the ultrasonic wave encounters the miniature metal reflective balls 209, a strong reflection will occur. This reflected signal appears as a bright spot in the ultrasonic image, which is in sharp contrast with the echo of the surrounding tissue, allowing the doctor to easily identify the position of the needle blade 203. The miniature metal reflective balls 209 arranged at a certain distance form a series of bright spots, which are distributed along the needle body 201 like a "signal chain". The doctor can accurately judge the direction of the needle body 201 and the depth of the needle blade 203 by observing the position and arrangement of these bright spots, thereby achieving precise positioning, avoiding unnecessary damage to the surrounding normal tissues, and improving the treatment effect. The miniature metal reflective balls 209 in each enhancement plate 207 are distributed in a circle, providing more comprehensive information on the position of the needle body 201, and making up for the defect that the signal of a single reflective ball is not obvious due to angle problems. Moreover, the signal formed by a circle of multiple micro-metal reflective balls 209 is more continuous on the ultrasound image, which is more helpful for the doctor to accurately determine the position and direction of the needle body 201. Under the action of the enhancement component 2, the ultrasound imaging effect is improved.
