[0002] An ultrasonic conductance instrument is an electronic medical device that uses ultrasonic waves as the main power to achieve needle-free injection and target drug penetration of drugs. When medical staff use an ultrasonic conductance therapeutic instrument for ultrasonic drug penetration treatment, they need to use the probe of the ultrasonic conductance therapeutic instrument to penetrate drugs into the human tissue to achieve the treatment purpose. Since the probe will enter the patient's body for drug injection operation, in order to ensure that there will be no cross-infection and pathogen transmission during treatment, such probes will use disposable in-vivo probes to ensure the safety of patients during treatment.

A medicine guide tube 2 is fixedly installed at the bottom of the threaded connection part 1, and a connection wire 3 is fixedly connected to the bottom of the threaded connection part 1. Moreover, an auxiliary disassembly mechanism 4 is installed at the top of the threaded connection part 1. The auxiliary disassembly mechanism 4 includes an annular bearing plate 41, a limiting spring 42, an annular anti-slip sleeve 43, an annular sealing ring 44, and an arc-shaped slider 45. The top of the annular bearing plate 41 is fixedly connected to the limiting spring 42, and the top of the limiting spring 42 is fixedly installed with the annular anti-slip sleeve 43. The bottom of the limiting spring 42 is fixedly connected to the top of the annular bearing plate 41, and the top of the limiting spring 42 is fixedly connected to the bottom of the annular anti-slip sleeve 43. Moreover, the annular anti-slip sleeve 43 and the annular bearing plate 41 form an elastic structure through the limiting spring 42. By setting the annular anti-slip sleeve 43 and the annular bearing plate 41 into an elastic structure, when medical staff loosen the annular anti-slip sleeve 43, it drives the annular sealing ring 44 to completely fit with the bottom of the annular baffle 61, so as to achieve the purpose of sealing and protecting the connection part. Moreover, the inner surface of the top of the annular anti-slip sleeve 43 is fixedly connected to the annular sealing ring 44. At the same time, arc-shaped sliders 45 are fixedly connected to the inner surface of the annular anti-slip sleeve 43 at equal intervals in a ring shape. Moreover, a locking component 5 is fixedly connected to the top of the threaded connection part 1. The connection component 6 is movably installed at the top of the auxiliary disassembly mechanism 4. The connection component 6 includes an annular baffle 61, an annular clamping plate 62, a limiting groove 63, and a limiting hole 64. The top of the annular baffle 61 is fixedly installed with the annular clamping plate 62. Moreover, limiting grooves 63 are opened at equal intervals in a ring shape on the top of the annular clamping plate 62. And limiting holes 64 are opened at equal intervals in a ring shape on the outer side of the annular clamping plate 62. The internal dimension of the limiting hole 64 is exactly the same as the external dimension of the arc-shaped clamping block 55. And the arc-shaped clamping block 55 and the annular clamping plate 62 form a clamping structure through the limiting hole 64. By setting the arc-shaped clamping block 55 and the annular clamping plate 62 into a clamping structure, the arc-shaped clamping block 55 is convenient to be clamped into the annular clamping plate 62 to complete the locking work. At the same time, the internal dimension of the limiting groove 63 is exactly the same as the external dimension of the limiting rod 57. The limiting rod 57 and the annular clamping plate 62 form a clamping structure through the limiting groove 63. Moreover, a rigid connection part 7 is fixedly connected to the top of the connection component 6, and an expansion part 8 is fixedly installed at the top of the rigid connection part 7.

[0023] As shown Figures 1 - 3As shown in the figure, a medicine guide tube 2 is fixedly installed at the bottom of the threaded connection part 1, and a connecting wire 3 is fixedly connected to the bottom of the threaded connection part 1. Moreover, an auxiliary disassembly mechanism 4 is installed at the top of the threaded connection part 1, and a locking component 5 is fixedly connected to the top of the threaded connection part 1. The locking component 5 includes a connecting column 51, an annular bearing column 52, a rectangular connecting sleeve 53, a telescopic rod 54, an arc-shaped clamping block 55, a locking spring 56 and a limiting rod 57. The top of the connecting column 51 is fixedly installed with an annular bearing column 52. The outer side of the connecting column 51 is slidably connected to the inner side of the arc-shaped slider 45. The outer side of the arc-shaped slider 45 is fixedly connected to the inner side of the annular anti-slip sleeve 43. Moreover, the annular anti-slip sleeve 43 and the connecting column 51 are configured as a sliding structure. By setting the annular anti-slip sleeve 43 and the connecting column 51 as a sliding structure, the annular anti-slip sleeve 43 can move up and down along the outer surface of the connecting column 51 more smoothly and stably. The outer surface of the annular bearing column 52 is fixedly connected with a rectangular connecting sleeve 53. Moreover, telescopic rods 54 are arranged at equal intervals in a ring shape on the outer surface of the rectangular connecting sleeve 53. At the same time, the extending end of the telescopic rod 54 is fixedly connected with an arc-shaped clamping block 55. A locking spring 56 is fixedly connected to the outer surface of the extending end of the telescopic rod 54. The end of the locking spring 56 is fixedly connected to the outer side of the rectangular connecting sleeve 53. The other end of the locking spring 56 is fixedly connected to the outer surface of the extending end of the telescopic rod 54. Moreover, the extending end of the telescopic rod 54 and the rectangular connecting sleeve 53 are configured as an elastic structure. By setting the telescopic rod 54 and the rectangular connecting sleeve 53 as an elastic structure, the telescopic rod 54 can drive the arc-shaped clamping block 55 to pass through the annular clamping plate 62 to complete the self-locking operation. The bottom of the connecting column 51 is fixedly installed with limiting rods 57 at equal intervals in a ring shape. The connecting component 6 is movably installed at the top of the auxiliary disassembly mechanism 4. The top of the connecting component 6 is fixedly connected with a rigid connecting part 7. Moreover, an expansion part 8 is fixedly installed at the top of the rigid connecting part 7.

[0024] In summary, for the disposable in-vivo probe that is convenient for quick disassembly and assembly, first, according to Figures 1 to 3In the structure shown, when medical staff need to replace the connection component 6, the medical staff grasp the annular baffle 61 and the threaded connection part 1 and perform docking processing between the two. At this time, the annular bearing column 52 drives the rectangular connecting sleeve 53 to move along the inner surface of the annular clamping plate 62. When the arc-shaped clamping block 55 moves to the limiting hole 64, the elastic force of the locking spring 56 causes the extension end of the telescopic rod 54 to drive the arc-shaped clamping block 55 to snap into the limiting hole 64, so as to complete the automatic docking work between the locking component 5 and the connection component 6. At this time, the elastic force of the limiting spring 42 causes the annular anti-slip sleeve 43 to drive the annular sealing ring 44 to completely fit with the bottom of the annular baffle 61, so as to achieve the purpose of sealing and protecting the connection. When the medical staff need to disassemble, they only need to grasp the annular anti-slip sleeve 43 and drive the annular anti-slip sleeve 43 to slide down along the outer surface of the annular clamping plate 62 through the sliding of the arc-shaped slider 45. When the annular anti-slip sleeve 43 drives the annular sealing ring 44 to move to the arc-shaped clamping block 55, the annular sealing ring 44 automatically squeezes the arc-shaped clamping block 55 inward, so that the arc-shaped clamping block 55 is separated from the limiting hole 64. Then the medical staff grasp the annular baffle 61 and take it out, thus greatly improving the replacement efficiency of the medical staff for the disposable in-vivo probe.
