Description

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

[0003] The current acoustic therapy puncture technology has been widely used, but it still has the following defects: when medical staff manually adjust the puncture needle insertion angle and speed during the puncture process, there is great uncertainty and error, and the operator's experience requirements are high, which is not friendly to novice doctors, and the adjustment accuracy is not high, which can easily cause secondary damage to patients. In addition, the existing puncture needle positioning frame is generally stuck on the ultrasonic probe, and then the puncture needle is installed on the puncture needle positioning frame for puncture. When puncture is performed using this setting, the angle adjustment of the puncture needle will be limited, and generally 2-3 levels of angle adjustment can be achieved, and stepless adjustment cannot be achieved.

DETAILED DESCRIPTION

[0031] 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 described embodiments 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.

[0032] In order to solve the technical problem that medical staff manually adjust the puncture needle insertion angle and speed during the puncture process, there is a large uncertainty and error, which is easy to cause secondary harm to the patient. Figure 1-Figure 8 , Fig.10 and Fig.12As shown, the following preferred technical solutions are provided:

[0033] An ultrasonic treatment puncture needle positioning device comprises an ultrasonic probe 1, which is used to locate the lesion site of a patient for subsequent puncture treatment. A positioning frame 2 is clamped on the ultrasonic probe 1, a ring plate 3 is fixedly arranged on the positioning frame 2, a moving mechanism 4 is arranged on the ring plate 3, the moving mechanism 4 moves various components on the ring plate 3 to determine the most suitable needle insertion angle, and is used to assist medical personnel in finding the best needle insertion angle. An adjusting mechanism 5 is fixedly arranged on the moving mechanism 4, a needle insertion mechanism 6 is fixedly arranged at one end of the adjusting mechanism 5 away from the moving mechanism 4, and the adjusting mechanism 5 is used for the angle of the needle insertion mechanism 6. Compared with the traditional 2-3 level angle adjustment, the adjusting mechanism 5 can realize stepless adjustment, and the adjustment angle range is wider, which has higher practicality and flexibility of use.

[0034] The needle insertion mechanism 6 is internally fixed with a plurality of clamping mechanisms 7. The puncture needle is placed inside the needle insertion mechanism 6 and fixed with the clamping mechanism 7 to facilitate subsequent puncture operations. The needle insertion mechanism 6 is provided with a rotating mechanism 8, which is meshed with the needle insertion mechanism 6. The medical staff can move the needle insertion mechanism 6 and the puncture needle together in a direction close to the human skin by rotating the rotating mechanism 8, which can be used for subsequent puncture operations. The annular plate 3 is internally provided with a plurality of adsorption mechanisms 9. During the puncture needle insertion process, it may be necessary to slightly move the ultrasonic probe 1 for a clearer observation. The position of the puncture needle and whether the puncture needle causes damage to the surrounding tissue. At this time, the adsorption mechanism 9 extends from the inside of the annular plate 3 and is firmly adsorbed on the human skin, thereby realizing the auxiliary positioning of the annular plate 3, the positioning frame 2 and other components. At this time, the electromagnetic force is used to release the clamping relationship between the ultrasonic probe 1 and the positioning frame 2, so that the ultrasonic probe 1 can move slightly in the inner circle of the annular plate 3, which is conducive to observing the puncture state of the puncture needle. After the observation is completed, the ultrasonic probe 1 is restored to its original position, and then the electromagnetic force is used to restore the clamping relationship between the ultrasonic probe 1 and the positioning frame 2, and the puncture can continue.

[0035] The positioning frame 2 includes a frame body 21, and a positioning groove 22 is provided on the inner side wall of the frame body 21. A positioning column 10 is fixedly installed on the side wall of the ultrasonic probe 1, and the positioning column 10 can be inserted and arranged inside the positioning groove 22. Through the coordination of the positioning groove 22 and the positioning column 10, the medical staff can ensure that the positioning frame 2 is installed in place on the ultrasonic probe 1 to prevent the positioning frame 2 from loosening during the puncture process. A pair of clamping arms 23 are symmetrically hinged on the frame body 21, and electromagnets 24 are fixedly installed on the inner side walls of the two clamping arms 23 away from the frame body 21, and the two electromagnets 24 are symmetrically arranged. When installing the positioning frame 2, firstly, opposite currents are passed through the two electromagnets 24. Flow makes the two electromagnets 24 present opposite magnetism, thereby making the two clamping arms 23 rotate in opposite directions. When the opening between the two clamping arms 23 is large enough, the positioning column 10 on the ultrasonic probe 1 is inserted into the interior of the positioning groove 22 to achieve the preliminary positioning of the ultrasonic probe 1 and the ultrasonic probe 1, and then the two electromagnets 24 are powered off. Since the hinge between the frame 21 and the clamping arms 23 has resilience, when the two electromagnets 24 are powered off, the two clamping arms 23 rotate in the direction close to the ultrasonic probe 1, thereby making the clamping arms 23 stuck on the ultrasonic probe 1, and the installation operation of the positioning frame 2 is achieved. When the positioning frame 2 needs to be removed, just reverse the above steps.

[0036] The annular plate 3 includes a plate body 31 fixedly mounted on the bottom surface of the frame body 21 , a track 32 is provided on the plate body 31 , the moving mechanism 4 is arranged on the track 32 , a plurality of mounting grooves 33 are provided on the bottom surface of the plate body 31 , and the adsorption mechanism 9 is arranged inside the mounting groove 33 .

[0037] The moving mechanism 4 includes a driving component 41 and a rotating wheel 42 rotatably mounted on the driving component 41. The rotating wheel 42 is rollingly arranged on the track 32. The driving component 41 drives the rotating wheel 42 to roll on the track 32, so that the moving mechanism 4, the adjusting mechanism 5, the needle insertion mechanism 6, the clamping mechanism 7 and the rotating mechanism 8 can move synchronously on the track 32, so as to assist medical personnel in finding the best needle insertion position. A mounting column 43 is fixedly mounted on the outer wall of the driving component 41, and a mounting plate 44 is fixedly sleeved on the mounting column 43. A plurality of brake members 46 are slidingly mounted on the mounting plate 44. A push plate 45 is fixedly mounted on one end of the plurality of brake members 46 away from the driving component 41. The push plate 45 is elastically connected to the side wall of the end of the mounting column 43 by a spring 1 47. An electromagnet 2 48 is fixedly mounted on the outer wall of the push plate 45, and a permanent magnet 49 is fixedly mounted on the side wall of the end of the mounting column 43, and the electromagnet 2 48 and the permanent magnet 49 are aligned.

[0038] When the best needle insertion position has been found, the electromagnet 2 48 is energized so that the electromagnet 2 48 and the permanent magnet 49 have the same magnetism, so that the push plate 45 will drive the brake member 46 to move in the direction away from the plate body 31, so that the brake member 46 is not in contact with the side wall of the plate body 31, and the braking relationship between the brake member 46 and the plate body 31 is released. Then, the drive assembly 41 drives the rotating wheel 42 to roll on the track 32, driving the moving mechanism 4, the adjusting mechanism 5, the needle insertion mechanism 6, the clamping mechanism 7 and the rotating mechanism 8 to move synchronously on the track 32 to the needle insertion position, and then the electromagnet 2 48 is de-energized. Under the elastic force of the spring 1 47, the push plate 45 will drive the brake member 46 to move in the direction close to the plate body 31, so that the brake member 46 and the side wall of the plate body 31 are restored to the contact state, and then the braking state is restored, so as to achieve the positioning effect of the moving mechanism 4, the adjusting mechanism 5, the needle insertion mechanism 6, the clamping mechanism 7 and the rotating mechanism 8, so as to facilitate the subsequent puncture operation.

[0039] The adjusting mechanism 5 includes a spherical member 51 fixedly mounted on the side wall of the end of the mounting column 43, a sleeve 52 movably sleeved on the spherical member 51, a positioning bolt 1 53 is threadedly connected to the sleeve 52, a rotating shaft 54 ​​is rotatably mounted through the end of the sleeve 52 away from the positioning bolt 1 53, a positioning bolt 2 55 is threadedly connected to the rotating shaft 54, a connecting member 56 is fixedly sleeved on the circumferential outer wall of the rotating shaft 54, and the connecting member 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 patient's lesion site. After the positioning is completed, the driving component 41 drives the rotating wheel 42 to roll on the track 32, driving the moving mechanism 4, the adjusting mechanism 5, the needle insertion mechanism 6, the clamping mechanism 7 and the rotating mechanism 8 to synchronously move the lesion site on the track 32, and then loosen the positioning bolt 53 to allow the sleeve 52 to rotate freely on the spherical part 51. After reaching a suitable angle, the positioning bolt 53 is tightened to achieve the positioning between the spherical part 51 and the sleeve 52. After the positioning operation between the spherical member 51 and the sleeve 52 is completed, the second positioning bolt 55 is loosened to adjust the angle of the needle insertion mechanism 6. After the angle adjustment of the needle insertion mechanism 6 is completed, the second positioning bolt 55 is tightened to realize the positioning operation of the needle insertion mechanism 6. After the above-mentioned positioning operation is completed, it means that the needle insertion angle of the puncture needle has been determined, and the subsequent puncture needle operation can be performed. Through the setting of the adjustment mechanism 5, the puncture angle of the puncture needle can be infinitely adjusted, and the adjustment angle range is wider, which can have high practicality and flexibility in use during the puncture process.

[0041] The needle insertion mechanism 6 comprises a mounting cylinder 61 fixedly mounted on the connecting member 56 , a slide cylinder 62 is slidably mounted inside the mounting cylinder 61 , and a plurality of tooth blocks 63 are fixedly mounted on the outer wall of the slide cylinder 62 .

[0042] The rotating mechanism 8 includes mounting frames 81 symmetrically fixedly mounted on the outer wall of the mounting tube 61 , and gears 82 are mounted on the two mounting frames 81 for common rotation. The gears 82 are meshedly connected with the gear block 63 , and a knob 83 is fixedly mounted on the side wall of one end of the gear 82 .

[0043] The clamping mechanism 7 includes a mounting seat 71 fixedly mounted on the side wall of the inner cavity of the slide cylinder 62, a clamping claw 72 is slidably mounted inside the mounting seat 71, the side wall of the clamping claw 72 is elastically connected to the side wall of the inner cavity of the mounting seat 71 through a spring 2 73, and a pair of electromagnets 3 74 are fixedly mounted on the opposite side walls of the two clamping claws 72.

[0044] Specifically, when the needle insertion mechanism 6, the clamping mechanism 7 and the mounting frame 81 are brought to the puncture position by the moving mechanism 4, the puncture needle is placed inside the slide 62, and then opposite currents are respectively applied to the electromagnets 74 on the two clamping jaws 72, so that the two electromagnets 74 attract each other, and then the two clamping jaws 72 approach each other and firmly clamp the puncture needle. After determining the final needle insertion position, the medical staff drives the gear 82 to rotate by twisting the knob 83 at a uniform speed. Since the gear 82 is meshed with the tooth block 63, the gear 82 rotates faster than the tooth block 63. During the process, the tooth block 63 will drive the slide tube 62 to slide in the direction close to the human skin inside the mounting tube 61 until the puncture needle is inserted into the specified position. The medical staff stops twisting the knob 83, and the puncture is completed. Through the above arrangement, the medical staff does not need to continuously hold the puncture needle for operation during the puncture process, which not only reduces the work pressure, but also avoids the uncertainty and error in the manual puncture process. In addition, the above arrangement has low experience requirements for the operator, is friendly to novice doctors, and is not easy to cause secondary harm to the patient.

[0045] In order to solve the technical problem that the ultrasonic probe 1 cannot be slightly moved to detect the periphery of the puncture needle during the puncture process, the puncture needle may touch the surrounding tissues and deviate. Figure 5-Figure 6 and Figure 8-Figure 11 As shown, the following preferred technical solutions are provided:

[0046] The adsorption mechanism 9 includes a mounting rod 91 fixedly mounted on the top surface of the inner cavity of the mounting groove 33, a piston 92 is fixedly mounted on the lower end of the mounting rod 91, a pair of electric push rods 95 are fixedly mounted on the top surface of the inner cavity of the mounting groove 33, and a piston cylinder 94 is fixedly mounted on the output ends of the two electric push rods 95. The piston 92 is movably arranged inside the piston cylinder 94, and the lower end of the piston cylinder 94 is connected to and fixedly mounted with a suction cup 93, and the suction cup 93 is made of a soft and tough material.

[0047] Specifically, Fig.12As shown, during the insertion of the puncture needle, it may be necessary to slightly move the ultrasonic probe 1 to more clearly observe the position of the puncture needle and whether the puncture needle causes damage to the surrounding tissue. At this time, the electric push rod 95 is started 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 on 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 push rod 95 can still drive the piston cylinder 94 to move downward for a distance, so that the inside of the suction cup 93 is evacuated to a negative pressure, and then the suction cup 93 is firmly adsorbed on the human skin, which is used to assist in positioning the plate body 31, the positioning frame 2 and other components. At this time, the two electromagnets 24 are oppositely passed. The current makes the two electromagnets 24 present opposite magnetism, thereby making the two clamping arms 23 rotate in opposite directions, and the clamping relationship between the ultrasonic probe 1 and the clamping arm 23 is released, so that the ultrasonic probe 1 can move slightly in the inner circle of the plate body 31, which is conducive to observing the puncture status of the puncture needle. After the observation is completed, the ultrasonic probe 1 is restored to its original position, and the electromagnetic force is used to restore the clamping relationship between the ultrasonic probe 1 and the clamping arm 23, and the puncture can be continued. With this setting, compared with the traditional puncture needle that is integrated with the ultrasonic probe 1 during use, it is more conducive to observing the status of the puncture needle, reducing the probability of the puncture needle causing secondary damage to the patient, and ensuring that the puncture needle punctures in place.
