Description

Technical Field

[0001] This invention relates to the field of puncture needle positioning technology, specifically to an ultrasonic therapy puncture needle positioning device. Background Technology

[0002] Ultrasound therapy is a technique that uses ultrasound technology to treat lesions. It has the advantages of precision, minimal invasiveness, and safety. A puncture needle is a thin and long medical device, mainly used to extract tissue fluid or inject drugs. In the medical process, ultrasound can be used in combination with the puncture needle to locate the lesion. Moreover, during the use of the puncture needle, in order to facilitate puncture, the puncture needle is also used in conjunction with a puncture needle positioning frame to achieve a better puncture effect.

[0003] While current acoustic therapy puncture techniques are widely used, they still have the following drawbacks: During the puncture process, medical personnel manually adjust the angle and speed of the puncture needle, which introduces significant uncertainty and error. Furthermore, it requires a high level of experience from the operator, making it unfriendly to novice doctors. The adjustment precision is also low, potentially causing secondary injury to the patient. In addition, existing puncture needle positioning frames are generally clipped onto the ultrasound probe, and the puncture needle is then mounted on the positioning frame for puncture. This method limits the angle adjustment of the puncture needle, typically allowing only 2-3 levels of adjustment, not stepless adjustment. Because the positioning frame is clipped onto the ultrasound probe, the puncture needle and probe are essentially one unit during use. This prevents the ultrasound probe from being moved slightly to probe the surrounding tissue during puncture, leading to the puncture needle hitting surrounding tissue or becoming misaligned.

[0004] To address the above issues, a positioning device for ultrasound-guided puncture needles is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasound therapy puncture needle positioning device. Using this device solves the problem mentioned above: when medical personnel manually adjust the insertion angle and speed of the puncture needle during the puncture process, there is significant uncertainty and error, which can easily cause secondary injury to the patient. Furthermore, it solves the problem that existing puncture needle positioning frames are fixed to the ultrasound probe, making the puncture needle and the ultrasound probe an integral unit during use. This prevents the ultrasound probe from being moved slightly to probe the surrounding area of ​​the puncture needle during the puncture process, leading to problems such as the puncture needle hitting surrounding tissue and misalignment.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an ultrasonic therapy puncture needle positioning device, comprising an ultrasonic probe, a positioning frame clamped on the ultrasonic probe, an annular plate fixedly mounted on the positioning frame, a moving mechanism mounted on the annular plate, an adjusting mechanism fixedly mounted on the moving mechanism, a needle insertion mechanism fixedly mounted at the end of the adjusting mechanism away from the moving mechanism, a plurality of clamping mechanisms fixedly mounted inside the needle insertion mechanism, a rotating mechanism mounted on the needle insertion mechanism, the rotating mechanism being meshed with the needle insertion mechanism, and a plurality of adsorption mechanisms mounted inside the annular plate.

[0007] Furthermore, the positioning component includes a frame, with a positioning groove on the inner side wall of the frame, and a positioning post fixedly installed on the side wall of the ultrasonic probe. The positioning post can be inserted into the positioning groove. A pair of clamping arms are symmetrically hinged on the frame, and an electromagnet is fixedly installed on the inner side wall of the two clamping arms away from the frame, and the two electromagnets are arranged in symmetrical positions.

[0008] Furthermore, the annular plate includes a plate body fixedly installed on the bottom surface of the frame, a track is provided on the plate body, a transfer mechanism is set on the track, and a number of mounting grooves are provided on the bottom surface of the plate body, with an adsorption mechanism set inside the mounting grooves.

[0009] Furthermore, the transfer mechanism includes a drive assembly and a rotating wheel rotatably mounted on the drive assembly. The rotating wheel is rolled on a track. A mounting column is fixedly mounted on the outer wall of the drive assembly. A mounting plate is fixedly sleeved on the mounting column. Several brake components are slidably mounted through the mounting plate. A push plate is fixedly mounted on the end of the several brake components away from the drive assembly. The push plate is elastically connected to the side wall of the end of the mounting column by a spring. An electromagnet is fixedly mounted on the outer wall of the push plate. A permanent magnet is fixedly mounted on the side wall of the end of the mounting column, and the electromagnet and the permanent magnet are aligned.

[0010] Furthermore, the adjustment mechanism includes a spherical component fixedly installed on the side wall of the end of the mounting column. A sleeve is movably fitted on the spherical component. A positioning bolt is threaded onto the sleeve. A rotating shaft is rotatably installed through the end of the sleeve away from the positioning bolt. A positioning bolt is threaded onto the rotating shaft. A connecting component is fixedly fitted on the outer circumference of the rotating shaft. The connecting component is fixedly connected to the needle insertion mechanism.

[0011] Furthermore, the needle insertion mechanism includes a mounting cylinder fixedly mounted on the connector, a sliding cylinder slidably mounted inside the mounting cylinder, and several toothed blocks fixedly mounted on the outer wall of the sliding cylinder.

[0012] Furthermore, the rotating mechanism includes mounting brackets symmetrically fixedly mounted on the outer wall of the mounting cylinder, with gears rotatably mounted on both mounting brackets, the gears meshing with the gear blocks, and a knob fixedly mounted on one end of the gear's side wall.

[0013] Furthermore, the clamping mechanism includes a mounting base fixedly installed on the side wall of the inner cavity of the slide cylinder. Two grippers are slidably installed inside the mounting base. The side walls of the two grippers are elastically connected to the side wall of the inner cavity of the mounting base by springs. A pair of electromagnets are fixedly installed on the opposite side walls of the two grippers.

[0014] Furthermore, the adsorption mechanism includes a mounting rod fixedly installed on the top surface of the inner cavity of the mounting groove, a piston fixedly installed at the lower end of the mounting rod, a pair of electric push rods fixedly installed on the top surface of the inner cavity of the mounting groove, a piston cylinder fixedly installed at the output ends of the two electric push rods, the piston being movably disposed inside the piston cylinder, and a suction cup being fixedly installed at the lower end of the piston cylinder.

[0015] Furthermore, the suction cup is made of a soft and resilient material.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] By adjusting the mechanism, the puncture angle of the needle can be infinitely adjusted, with a wider adjustment range, providing high practicality and flexibility during puncture. The needle insertion, clamping, and rotating mechanisms eliminate the need for medical personnel to continuously hold the needle during puncture, reducing workload and avoiding uncertainties and errors inherent in manual puncture. Furthermore, it requires less experience from the operator, making it more suitable for novice doctors and reducing the risk of secondary injury to the patient. Compared to traditional puncture needles that are integrated with the ultrasound probe during use, this invention allows for better observation of the needle's status, reduces the probability of secondary injury to the patient, and ensures accurate puncture.

Detailed Implementation

[0031] 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.

[0032] To address the technical problem of significant uncertainty and error in manually adjusting the angle and speed of needle insertion during puncture procedures, which can easily cause secondary injury to patients, such as... Figures 1-8 , Figure 10 and Figure 12 As shown, the following preferred technical solutions are provided:

[0033] An ultrasonic therapy puncture needle positioning device includes an ultrasonic probe 1, which is used to locate the lesion site of the patient to facilitate subsequent puncture treatment. A positioning frame 2 is mounted on the ultrasonic probe 1, and an annular plate 3 is fixedly mounted on the positioning frame 2. A moving mechanism 4 is mounted on the annular plate 3, which moves the components along the annular plate 3 to determine the most suitable needle insertion angle, thus assisting medical personnel in finding the optimal needle insertion angle. An adjustment mechanism 5 is fixedly mounted on the moving mechanism 4, and a needle insertion mechanism 6 is fixedly mounted at the end of the adjustment mechanism 5 away from the moving mechanism 4. The adjustment mechanism 5 is used to adjust the angle of the needle insertion mechanism 6. Compared with the traditional 2-3 level angle adjustment, the adjustment mechanism 5 can achieve stepless adjustment, with a wider adjustment range, and has higher practicality and flexibility of use.

[0034] The needle insertion mechanism 6 has several clamping mechanisms 7 fixedly installed inside. The puncture needle is inserted into the needle insertion mechanism 6 and fixed in place by the clamping mechanisms 7 to facilitate subsequent puncture operations. The needle insertion mechanism 6 is equipped with a rotating mechanism 8, which is engaged with the needle insertion mechanism 6. Medical personnel can move the needle insertion mechanism 6 and the puncture needle together towards the skin by rotating the rotating mechanism 8, which can be used for subsequent puncture operations. The annular plate 3 has several suction mechanisms 9 inside. During the needle insertion process, the ultrasound probe 1 may need to be slightly moved for clearer observation. The position of the puncture needle and whether it has caused damage to the surrounding tissue are determined. At this time, the adsorption mechanism 9 extends from the inside of the annular plate 3 and firmly adheres to the human skin, providing auxiliary positioning for the annular plate 3, the positioning frame 2, and other components. Then, the electromagnetic force is used to release the locking relationship between the ultrasonic probe 1 and the positioning frame 2, allowing the ultrasonic probe 1 to move slightly within the inner ring of the annular plate 3, which is beneficial for observing the puncture status of the puncture needle. After the observation is completed, the ultrasonic probe 1 is returned to its original position, and the electromagnetic force is used to restore the locking relationship between the ultrasonic probe 1 and the positioning frame 2, so that the puncture can continue.

[0035] The positioning frame 2 includes a frame body 21. A positioning groove 22 is formed on the inner wall of the frame body 21. A positioning post 10 is fixedly installed on the side wall of the ultrasound probe 1. The positioning post 10 can be inserted into the positioning groove 22. Through the cooperation of the positioning groove 22 and the positioning post 10, medical personnel can ensure that the positioning frame 2 is properly installed on the ultrasound probe 1, preventing the positioning frame 2 from becoming loose during puncture. A pair of clamping arms 23 are symmetrically hinged to the frame body 21. Electromagnets 24 are fixedly installed on the inner wall of the ends of the two clamping arms 23 away from the frame body 21, and the two electromagnets 24 are symmetrically positioned. When installing the positioning frame 2, opposite currents are first applied to the two electromagnets 24. The current causes the two electromagnets 24 to exhibit opposite magnetic properties, which in turn causes the two clamping arms 23 to rotate in opposite directions. When the opening between the two clamping arms 23 is large enough, the positioning pin 10 on the ultrasonic probe 1 is inserted into the positioning groove 22 to achieve the initial positioning of the ultrasonic probe 1. Then, the two electromagnets 24 are de-energized. Since the hinge between the frame 21 and the clamping arms 23 has elasticity, when the two electromagnets 24 are de-energized, the two clamping arms 23 rotate toward the ultrasonic probe 1, thereby locking the clamping arms 23 onto the ultrasonic probe 1, thus realizing the installation operation of the positioning frame 2. When it is necessary to remove the positioning frame 2, simply reverse the above steps.

[0036] The annular plate 3 includes a plate 31 fixedly installed on the bottom surface of the frame 21. A track 32 is provided on the plate 31, and a moving mechanism 4 is provided on the track 32. Several mounting grooves 33 are provided on the bottom surface of the plate 31, and an adsorption mechanism 9 is provided inside the mounting grooves 33.

[0037] The transfer mechanism 4 includes a drive assembly 41 and a rotating wheel 42 rotatably mounted on the drive assembly 41. The rotating wheel 42 is rolled on a track 32. The drive assembly 41 drives the rotating wheel 42 to roll on the track 32, enabling the transfer mechanism 4, adjustment mechanism 5, needle insertion mechanism 6, clamping mechanism 7, and rotation mechanism 8 to move synchronously on the track 32. This helps medical personnel find the optimal needle insertion position. A mounting post 43 is fixedly mounted on the outer wall of the drive assembly 41. A mounting plate 44 is fixedly sleeved on the mounting post 43. Several brake components 46 are slidably mounted through the mounting plate 44. A push plate 45 is fixedly mounted on the end of the brake components 46 away from the drive assembly 41. The push plate 45 and the side wall of the end of the mounting post 43 are elastically connected by a spring 47. An electromagnet 48 is fixedly mounted on the outer wall of the push plate 45. A permanent magnet 49 is fixedly mounted on the side wall of the end of the mounting post 43, and the electromagnet 48 and the permanent magnet 49 are aligned.

[0038] Once the optimal needle insertion position has been found, electromagnet 48 is energized, causing it to have the same magnetism as permanent magnet 49. This causes push plate 45 to move brake 46 away from plate 31, preventing brake 46 from contacting the side wall of plate 31 and thus releasing the braking relationship between brake 46 and plate 31. Then, drive assembly 41 to drive wheel 42 to roll on track 32, causing transfer mechanism 4, adjustment mechanism 5, needle insertion mechanism 6, clamping mechanism 7, and rotation mechanism 8 to move synchronously on track 32 to the needle insertion position. After electromagnet 48 is de-energized, under the elastic force of spring 47, push plate 45 moves brake 46 closer to plate 31, restoring contact between brake 46 and the side wall of plate 31 and resuming the braking state. This achieves the positioning effect for transfer mechanism 4, adjustment mechanism 5, needle insertion mechanism 6, clamping mechanism 7, and rotation mechanism 8, facilitating subsequent puncture operations.

[0039] The adjusting mechanism 5 includes a spherical part 51 fixedly installed on the side wall of the end of the mounting column 43. A sleeve 52 is movably sleeved on the spherical part 51. A positioning bolt 53 is threadedly connected to the sleeve 52. A rotating shaft 54 ​​is rotatably installed through the end of the sleeve 52 away from the positioning bolt 53. A positioning bolt 55 is threadedly connected to the rotating shaft 54. A connecting piece 56 is fixedly sleeved on the outer circumference of the rotating shaft 54. The connecting piece 56 is fixedly connected to the needle insertion mechanism 6.

[0040] Specifically, before performing ultrasonic puncture, the ultrasonic probe 1 is first used to locate the lesion site on the patient. After the location is determined, the drive assembly 41 drives the rotating wheel 42 to roll on the track 32, which in turn drives the moving mechanism 4, adjusting mechanism 5, needle insertion mechanism 6, clamping mechanism 7, and rotating mechanism 8 to move the lesion site synchronously on the track 32. Then, the positioning bolt 53 is loosened, allowing the sleeve 52 to rotate freely on the spherical part 51. After reaching the appropriate angle, the positioning bolt 53 is tightened, thus achieving the positioning between the spherical part 51 and the sleeve 52. After the positioning operation between the spherical part 51 and the sleeve 52 is completed, loosen the second positioning bolt 55 and adjust the angle of the needle insertion mechanism 6. After the angle of the needle insertion mechanism 6 is adjusted, tighten the second positioning bolt 55 to realize the positioning operation of the needle insertion mechanism 6. After the above positioning operation is completed, it means that the needle insertion angle of the puncture needle has been determined and subsequent puncture needle operations can be carried out. By adjusting the setting of the mechanism 5, the puncture angle of the puncture needle can be infinitely adjusted, the adjustment angle range is wider, and it has high practicality and flexibility in use during the puncture process.

[0041] The needle insertion mechanism 6 includes a mounting cylinder 61 fixedly mounted on the connector 56, a sliding cylinder 62 slidably mounted inside the mounting cylinder 61, and a number of toothed blocks 63 fixedly mounted on the outer wall of the sliding cylinder 62.

[0042] The rotating mechanism 8 includes mounting brackets 81 symmetrically fixedly mounted on the outer side wall of the mounting cylinder 61. Gears 82 are rotatably mounted on both mounting brackets 81. Gears 82 are meshed with tooth blocks 63, and a knob 83 is fixedly mounted on one side wall of one end of gear 82.

[0043] The clamping mechanism 7 includes a mounting base 71 fixedly installed on the inner wall of the slide cylinder 62. Two grippers 72 are slidably installed inside the mounting base 71. The side walls of the two grippers 72 are elastically connected to the side wall of the inner cavity of the mounting base 71 by springs 73. A pair of electromagnets 74 are fixedly installed on the opposite side walls of the two grippers 72.

[0044] Specifically, when the transfer mechanism 4 brings the needle insertion mechanism 6, clamping mechanism 7, and mounting bracket 81 to the puncture position, the puncture needle is placed inside the slide cylinder 62. Then, opposite currents are supplied to the electromagnets 74 on the two grippers 72, causing the two electromagnets 74 to attract each other, which in turn causes the two grippers 72 to move closer together and firmly clamp the puncture needle. After determining the final needle insertion position, the medical staff rotates the gear 82 by turning the knob 83 at a constant speed. Because the gear 82 is meshed with the gear block 63, the rotation of the gear 82... During the procedure, the toothed block 63 drives the sliding cylinder 62 to slide towards the skin inside the mounting cylinder 61 until the puncture needle is inserted into the designated position. At this point, the medical staff stops turning the knob 83, and the puncture is complete. With this setup, the medical staff does not need to continuously hold the puncture needle during the puncture process, which not only reduces the workload but also avoids the uncertainty and error in manual puncture. In addition, the above setup requires less experience from the operator, is more user-friendly for novice doctors, and is less likely to cause secondary harm to the patient.

[0045] To address the technical issues that arise during puncture, where the ultrasound probe 1 cannot be moved even slightly to probe the area around the puncture needle, leading to the needle hitting surrounding tissue and becoming misaligned, such as... Figures 5-6 and Figures 8-11 As shown, the following preferred technical solutions are provided:

[0046] The adsorption mechanism 9 includes an installation rod 91 fixedly installed on the top surface of the inner cavity of the installation groove 33. A piston 92 is fixedly installed at the lower end of the installation rod 91. A pair of electric push rods 95 are fixedly installed on the top surface of the inner cavity of the installation groove 33. The output ends of the two electric push rods 95 are fixedly installed together with a piston cylinder 94. The piston 92 is movably disposed inside the piston cylinder 94. A suction cup 93 is fixedly installed at the lower end of the piston cylinder 94. The suction cup 93 is made of a soft and tough material.

[0047] Specifically, such as Figure 12As shown, during the insertion of the puncture needle, the ultrasonic probe 1 may need to be slightly moved to more clearly observe the position of the puncture needle and whether the puncture needle has caused damage to the surrounding tissue. At this time, the electric actuator 95 is activated to extend and drive the piston cylinder 94 to extend from the inside of the mounting groove 33 and firmly press the suction cup 93 onto the human skin. Since the suction cup 93 is made of a soft and tough material, when the suction cup 93 contacts the human skin, the electric actuator 95 can still drive the piston cylinder 94 to move downward a certain distance, so that the inside of the suction cup 93 is drawn into a negative pressure, thereby firmly adhering the suction cup 93 to the human skin, which is used to assist in the positioning of the plate 31, the positioning frame 2 and other components. At this time, opposite currents are supplied to the two electromagnets 24. The current causes the two electromagnets 24 to exhibit opposite magnetism, which in turn causes the two clamping arms 23 to rotate in opposite directions. The locking relationship between the ultrasonic probe 1 and the clamping arms 23 is released, allowing the ultrasonic probe 1 to move slightly within the inner ring of the plate 31. This facilitates observation of the puncture needle's puncture status. After observation, the ultrasonic probe 1 is returned to its original position, and then the locking relationship between the ultrasonic probe 1 and the clamping arms 23 is restored using electromagnetic force, allowing puncture to continue. Compared to the traditional method where the puncture needle and ultrasonic probe 1 are integrated during use, this setup is more conducive to observing the puncture needle's status, reducing the probability of secondary injury to the patient, and ensuring that the puncture needle is inserted correctly.
