Technical Field

[0001] The present invention relates to the technical field of copper stranding machines, and specifically, to an intravascular shock wave device and an intravascular shock wave system. Background Art

[0002] Currently in the medical field, due to the advantages of being able to directly reach the lesion and facilitating accurate inspection and surgical operations, the use of interventional devices is increasing. Interventional devices are generally equipped with guide wires. By implanting the guide wire into the cavity or blood vessel of the detected object and moving along the natural cavity of the detected object to the target position, the purpose of reducing surgical operation injuries can be achieved.

[0003] The patent with the publication number CN 113440215A discloses a shock wave generating device and a catheter system: the shock wave generating device is arranged as a plurality of coaxially arranged annular structures. One of the annular structures of the shock wave generating device includes an electrode pair and a non-conductive gap, and the non-conductive gap is arranged between the two electrodes of the electrode pair; the electrode pair is composed of flexible electrodes.

[0004] In the above application, through the shock wave generating device, it is difficult to solve the function of detecting the operating voltage of the shock wave generating device during use, resulting in the operating voltage of the shock wave generating device exceeding the safety voltage during use and causing damage to the patient. Therefore, we propose an intravascular shock wave device and an intravascular shock wave system. Summary of the Invention

A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A moving rod is fixedly connected to the side of the threaded sleeve. The side of the moving rod penetrates through the side of the treatment instrument body and is slidably connected to the side of the treatment instrument body. One end of the moving rod away from the side of the threaded sleeve is fixedly connected with a fixed sleeve. An adjusting stud is slidably connected to the top of the fixed sleeve. An adjusting nut is threadedly connected to the circumferential surface of the adjusting stud.

[0007] A coil is fixedly connected inside the treatment instrument body. A chute is provided inside the treatment instrument body. An iron block is slidably connected inside the chute. A trigger rod is fixedly connected to the side of the iron block. A start button is provided at the bottom of the motor. The function of the coil is to detect the voltage emitted by the treatment instrument body. The function of the iron block is to move the iron block through the chute when the coil generates magnetism by electricity. The function of the trigger rod is to trigger the start button.

[0008] The trigger end of the start button is located on the displacement track of the trigger rod. The function of the trigger end of the start button being located on the displacement track of the trigger rod is to ensure that the trigger rod can press the trigger end of the start button when it moves.

[0009] A fixing mechanism is provided on the circumferential surface of the impact catheter. The fixing mechanism includes an installation box. The installation box is fixedly penetrated through the circumferential surface of the impact catheter. A storage groove is provided inside the installation box. A pull wire is slidably connected inside the storage groove. One end of the pull wire is fixedly connected to a fixing belt. The side of the fixing belt is slidably connected to the inside of the storage groove. The other end of the fixing belt is fixedly connected to the bottom of the installation box. A pull ring is fixedly connected to the end of the pull wire far from the side of the fixing belt. The function of providing a fixing mechanism on the circumferential surface of the impact catheter is to fix the entire impact catheter when it is inserted into the patient's body.

[0010] A limiting sleeve is fixedly connected to the side of the fixing belt. A sliding sleeve is fixedly connected to the circumferential surface of the operating handle. The function of the limiting sleeve is to be stably fixed when the fixing belt is pulled. The function of the sliding sleeve is to convey the pull wire and prevent the pull wire from winding.

[0011] The number of the sliding sleeves is set to three and they are distributed on the circumferential surface of the operating handle. The function of the number of the sliding sleeves being set to three and distributed on the circumferential surface of the operating handle is to stably convey the pull wire.

[0012] A locking mechanism is provided inside the impact catheter. The locking mechanism includes a branch wire. One end of the branch wire is fixedly connected to the circumferential surface of the pull wire. The circumferential surface of the branch wire penetrates through and is slidably connected to the circumferential surface of the impact catheter. The end of the branch wire far from the circumferential surface of the pull wire is fixedly connected to a moving block. An inlay groove is provided on the circumferential surface of the impact catheter. A locking plate is slidably connected inside the inlay groove. A force-bearing rod is fixedly connected to the side of the locking plate.

[0013] A reset spring is fixedly connected inside the impact catheter. One end of the reset spring away from the inside of the impact catheter is fixedly connected to the circumferential surface of the force rod. The function of the reset spring is that when the force rod is not stressed, the locking plate is reset by the elasticity of the reset spring.

[0014] The number of the embedding grooves, the locking plates and the reset springs is set to two, and they are symmetric with each other along the vertical central axis of the impact catheter. The inclined surface of the force rod is located on the displacement track of the moving block. The fact that the number of the embedding grooves, the locking plates and the reset springs is set to two and they are symmetric with each other along the vertical central axis of the impact catheter serves to stably lock the delivery head of the impact catheter. The fact that the inclined surface of the force rod is located on the displacement track of the moving block serves to ensure that the moving block can push the force rod during the movement.

[0015] An intravascular shock wave system includes a detection module, a fixing module and an impact module. A trigger unit is arranged at the output end of the detection module, a locking unit is arranged at the output end of the fixing module, and a locking unit is arranged at the output end of the impact module.

[0016] The working principle and beneficial effects of the present invention are as follows: 1. Through the mutual cooperation among components such as the motor, the fixed sleeve and the coil of the voltage detection mechanism of the present invention, when other people accidentally touch the control panel during the use of the treatment instrument body, the voltage of the treatment instrument body exceeds the safe voltage. At this time, the coil detects that the voltage is too high, and generates a magnetic force through the characteristics of the coil to drive the iron block to move, so that the trigger rod presses the trigger end of the start button to start the motor. Then, the fixed sleeve moves from left to right to drive the connecting head of the connecting wire away from the side of the treatment instrument body, so that the operating handle is powered off, and further the impact catheter fails. Such a design achieves the effect of detecting the use voltage of the treatment instrument body, and effectively prevents the damage to the patient caused by the use voltage of the treatment instrument body exceeding the safe voltage.

[0017] 2. Through the mutual cooperation among components such as the pull wire, the fixing belt and the sliding sleeve of the fixing mechanism of the present invention, when medical staff use the treatment instrument body and insert the impact catheter into the patient, when the delivery head of the impact catheter reaches the treatment site, the medical staff can pull the pull ring to drive the pull wire to drive the fixing belt into the storage groove, so that the fixing belt shrinks into the installation box, and further the fixing belt fixes the patient. Such a design achieves the effect of fixing the impact catheter, and effectively prevents the damage to the patient caused by the shaking of the impact catheter due to external forces.

[0018] 3. Through the mutual cooperation among components such as the branch line, locking plate, and return spring of the locking mechanism in the present invention, when the pull ring of the medical staff is pulled to drive the pull wire to slide inside the sliding sleeve, the branch line moves inside the impact catheter under the action of the pulling force, causing the moving block to move under the pulling force. During the movement of the moving block, the force-receiving rod is pushed, so that the force-receiving rod drives the locking plate to move under the thrust, and then leaves the inside of the embedding groove to lock the treatment site, and then stably performs impact treatment on the treatment site. Such a design achieves the effect of locking the delivery head of the impact catheter, effectively ensuring that the delivery head of the impact catheter is locked at the treatment site and preventing the delivery head of the impact catheter from deviating due to the impact force.

[0019] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manner

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0024] Embodiment 1 As Figures 1 to 8As shown in the figure, this embodiment proposes an intravascular shock wave device, which includes a treatment instrument body 1. A control panel 2 is arranged on the side of the treatment instrument body 1. A connecting wire 3 is slidably connected to the side of the treatment instrument body 1. One end of the connecting wire 3 away from the side of the treatment instrument body 1 is provided with an operating handle 4. The output end of the operating handle 4 is provided with an impact catheter 5. A voltage detection mechanism 6 is arranged inside the treatment instrument body 1; The voltage detection mechanism 6 includes a motor 61. The side of the motor 61 is fixedly connected inside the treatment instrument body 1. The output shaft of the motor 61 is fixedly connected with a threaded rod 62. A threaded sleeve 63 is threadedly connected to the circumferential surface of the threaded rod 62. A moving rod 64 is fixedly connected to the side of the threaded sleeve 63. The side of the moving rod 64 penetrates through the side of the treatment instrument body 1 and is slidably connected to the side of the treatment instrument body 1. One end of the moving rod 64 away from the side of the threaded sleeve 63 is fixedly connected with a fixed sleeve 65. An adjusting stud 66 is slidably connected to the top of the fixed sleeve 65. An adjusting nut 67 is threadedly connected to the circumferential surface of the adjusting stud 66. A coil 68 is fixedly connected inside the treatment instrument body 1. A chute 69 is opened inside the treatment instrument body 1. An iron block 610 is slidably connected inside the chute 69. A trigger rod 611 is fixedly connected to the side of the iron block 610. A start button 612 is arranged at the bottom of the motor 61. The function of the coil 68 is to detect the voltage emitted by the treatment instrument body 1. The function of the iron block 610 is to make the iron block 610 move through the chute 69 when the coil 68 generates magnetism by electricity. The function of the trigger rod 611 is to trigger the start button 612. The trigger end of the start button 612 is located on the displacement track of the trigger rod 611. The function of the trigger end of the start button 612 being located on the displacement track of the trigger rod 611 is to ensure that the trigger rod 611 can press the trigger end of the start button 612 when it moves.

[0025] In this embodiment, before using the treatment instrument body 1, medical staff first stably install the fixed sleeve 65 on the connector of the connecting wire 3 through the adjusting stud 66 and the adjusting nut 67. During the use of the treatment instrument body 1, when other people accidentally touch the control panel 2, the voltage of the treatment instrument body 1 exceeds the safe voltage. At this time, the coil 68 detects that the voltage is too high and generates magnetism through the characteristics of the coil 68. As a result, the iron block 610 is subjected to the magnetic force and moves upward through the chute 69. The upward movement of the iron block 610 drives the trigger rod 611 to move upward. During the upward movement of the trigger rod 611, the trigger end of the start button 612 is pressed, causing the motor 61 to start. The output shaft of the motor 61 rotates counterclockwise. The counterclockwise rotation of the output shaft of the motor 61 drives the threaded rod 62 to rotate counterclockwise. The threaded sleeve 63 threadedly connected to the circumferential surface of the threaded rod 62 moves from left to right. The movement of the threaded sleeve 63 from left to right drives the fixed sleeve 65 to move from left to right through the moving rod 64. The movement of the fixed sleeve 65 from left to right drives the connector of the connecting wire 3 to leave the side of the treatment instrument body 1, causing the operating handle 4 to lose power, and further causing the impact catheter 5 to fail.

The function of the limiting sleeve 76 is to stably fix the fixing band 74 when it is pulled. The function of the sliding sleeve 77 is to convey the pull wire 73 to prevent the pull wire 73 from being wound. The number of sliding sleeves 77 is set to three and they are distributed on the circumferential surface of the operating handle 4. The number of sliding sleeves 77 is set to three and they are distributed on the circumferential surface of the operating handle 4 to stably convey the pull wire 73. A locking mechanism 8 is provided inside the impact catheter 5. The locking mechanism 8 includes a branch wire 81. One end of the branch wire 81 is fixedly connected to the circumferential surface of the pull wire 73.

A fitting groove 83 is formed on the circumferential surface of the impact catheter 5. A locking plate 84 is slidably connected inside the fitting groove 83. A force-receiving rod 85 is fixedly connected to the side surface of the locking plate 84. The side surface of the force-receiving rod 85 penetrates through and is slidably connected to the circumferential surface of the impact catheter 5.

The fixing belt 74 enters the storage groove 72 through the limiting sleeve 76, so that the fixing belt 74 contracts into the installation box 71, and further enables the fixing belt 74 to fix the patient. When the impact catheter 5 is started, to prevent the output head of the impact catheter 5 from shaking under the impact force in the patient's body and causing injury to the patient's body, while the medical staff pulls the pull ring 75 to drive the pull wire 73 to slide inside the sliding sleeve 77, the pull wire 81 is pulled by the force and moves inside the impact catheter 5, so that the moving block 82 moves under the pull force.
