Description

Technical Field

[0001] The invention belongs to the field of urinary stone crushing devices, in particular to a urinary stone crushing device. Background Art

[0002] Extracorporeal lithotripsy is usually used to break up small stones in urology. Extracorporeal lithotripsy, also known as extracorporeal shock wave lithotripsy, is a non-invasive method for treating urinary stones. The general operating principle of extracorporeal lithotripsy is to use X-ray or ultrasonic imaging technology to accurately locate the position of the stone through the detection head, and then use ultrasonic focusing to amplify the energy at the focus. The stone is placed precisely at the focus so that energy can be concentrated to crush the stone. In this process, the cooperation of the human body is required to place the stone where the ultrasound can act.

[0003] A patent document with announcement number CN117838300A discloses the technical field of lithotripsy in urology, and specifically discloses a stone crushing device, including a cover body mechanism, which includes a first airbag, a second airbag, a third airbag and a metal wire. The present invention forms a protective cover with an inlet end through the first airbag, the second airbag and the third airbag. When performing laser lithotripsy on the stones, it effectively avoids the problem of scratches on tissues such as the ureter and urethral mucosa caused by large or angular stones.

[0004] In traditional technology, urological stones are crushed by extracorporeal lithotripsy. In this process, the cooperation of the human body is required to align the location of the stone with the action area of ​​the ultrasonic probe.

In the existing technology, the problem of human posture is basically solved by installing a medical bed to let the patient lie down or tilted. However, in reality, the ultrasonic probe is generally not easy to move, and the stone part of the human body needs to be aligned with the action area of ​​the ultrasonic probe. In this way, the human body is not comfortable during the long stone crushing process, and the human body may move, resulting in poor crushing effect of the ultrasonic probe.

The urinary stone crushing device described in the present invention uses X-ray or ultrasonic imaging technology to accurately locate the position of the stone through a detection head, and then adjusts the human body posture so that the stone position is aligned with the area that the ultrasonic head can act on. In order to keep the human body posture for a longer time without deformation, the human body needs to maintain a comfortable posture. After the stone position is aligned, the human body has contacted the positioning component, and the human skin is in contact with the top plate. The rotating shaft arranged under the top plate can rotate inside the component column to adapt to the human body posture at this time, allowing the patient to maintain the posture in a comfortable state.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1-4 As shown, a urinary stone crushing device according to an embodiment of the present invention comprises a device body 1 and a detection head 2 installed on the top of the device body 1, the detection head 2 is arranged downwards and is used to detect the location of stones, an ultrasonic generator is arranged inside the device body 1, and an ultrasonic head 3 is externally connected to the ultrasonic generator, a medical bed 5 is installed directly below the detection head 2, a ventilation groove 6 is opened through the inside of the medical bed 5, a positioning component 4 is fixedly installed inside the ventilation groove 6, and the ultrasonic head 3 is arranged toward the upper end of the positioning component 4;

[0036] A supporting base plate 11 is installed at the lower end of the device body 1, and the supporting base plate 11 is fixedly connected to the bottom surface of the medical bed 5 to support the medical bed 5. The positioning assembly 4 includes a fixed column 8 fixedly installed on the supporting base plate 11 and a top plate 7 rotatably installed above the fixed column 8. An inner ring groove 81 is opened inside the fixed column 8, and a component column 9 is fixedly installed inside the inner ring groove 81. A rotating shaft 75 is installed below the top plate 7, and the rotating shaft 75 is rotatably installed inside the component column 9.

[0037] Specifically, in the urological stone crushing operation, the extracorporeal lithotripsy is adopted. First, the patient is asked to lie or lie prone on the medical bed 5. Because the stone crushing time is long, in order to avoid the human body from being in contact with the medical bed 5 for too long, and to avoid overheating reaction and causing stress to the patient, a ventilation groove 6 is opened on the medical bed 5. The detection head 2 uses X-ray imaging technology to locate the stone position. X-ray imaging technology can generate clear images of stones and predict the composition of stones through X-ray scanning with different energies. Therefore, the detection head 2 can use X-rays to accurately locate the position of the stone, and then adjust the human body posture so that the stone position is aligned with the ultrasonic head 3. In order to keep the human body posture longer without deformation, the human body needs to maintain a comfortable posture. After the stone position is aligned, the human body has contacted the positioning component 4, and the human skin is in contact with the top plate 7. The rotating shaft 75 arranged under the top plate 7 can be rotated inside the component column 9 to adapt to the human body posture at this time, so that the patient can maintain the posture in a comfortable state. Compared with the traditional technology, the medical bed 5 with a fixed shape cannot be adjusted to adapt to the human body posture. In this case, the angle can be automatically adjusted to keep in fit with the human body. Then, under the power drive, the ultrasonic head 3 emits ultrasonic waves to crush the stones. After crushing, the stones can be discharged through the patient's urethra.

[0038] like Figure 3-4 As shown, an elastic pad 71 is fixedly installed on the top of the top plate 7, an elastic ring 72 is fixedly installed on the bottom of the top plate 7, the lower side of the elastic ring 72 is connected to the upper end surface of the fixed column 8, an arc block 73 is fixedly installed on the lower end surface of the top plate 7, a connecting column 74 is fixedly installed on the arc block 73, and the arc block 73 is connected to the rotating shaft 75 through the connecting column 74.

[0039] Specifically, the setting of the elastic pad 71 can prevent the human body from having hard friction and thus causing the stone to move. The elastic ring 72 is connected between the fixed column 8 and the top plate 7. The retractable characteristics of the elastic ring 72 can prevent foreign debris from entering the position between the top plate 7 and the fixed column 8.

[0040] like Figure 5-6 As shown, a circular shaft groove 91 is provided inside the component column 9, and the rotating shaft 75 is rotatably installed inside the circular shaft groove 91. A telescopic motor 92 is installed below the component column 9, and the telescopic motor 92 is fixedly installed inside the fixed column 8. The telescopic motor 92 is connected to the telescopic column 93 through an axis. An annular groove 94 is provided at the bottom of the circular shaft groove 91, and an arc bottom plate 95 is slidably installed inside the annular groove 94. The telescopic column 93 penetrates the component column 9 and is connected to the bottom of the arc bottom plate 95. The arc surface on the arc bottom plate 95 is consistent with the outer curvature of the rotating shaft 75, and the arc surface on the arc bottom plate 95 is rough.

[0041] Specifically, after the patient has undergone stone crushing, that is, a comfortable human posture is maintained. At this time, the rotating shaft 75 has rotated inside the circular shaft groove 91. In order to prevent the top plate 7 from rotating again, affecting the stone position and reducing the stone crushing efficiency, the telescopic column 93 is driven by the telescopic motor 92 to move upward until the arc bottom plate 95 is in close contact with the bottom of the rotating shaft 75 at this time, that is, the arc surface of the arc bottom plate 95 is against the bottom surface of the rotating shaft 75, so that the rotating shaft 75 no longer rotates easily, and the arc surface of the arc bottom plate 95 is roughly arranged, which further increases the friction of the rotation of the rotating shaft 75, further avoids the rotating shaft 75 from rotating again, maintains the human posture, and is beneficial to the crushing of urological stones. The rise of the arc bottom plate 95 can be a spiral rise method, which can be more precise.

[0042] like Figure 7 As shown, a plurality of sliding grooves 82 and cylindrical grooves 83 are provided inside the fixed column 8, and the plurality of sliding grooves 82 are connected with the cylindrical groove 83. The diameter of the cylindrical groove 83 is larger than the diameter of the sliding groove 82. The plurality of sliding grooves 82 and cylindrical grooves 83 are arranged in a ring shape inside the fixed column 8. A lifting column 84 is slidably installed inside the sliding grooves 82 and the cylindrical grooves 83. An annular spring 85 is installed at the bottom of the lifting column 84, and the lower end of the annular spring 85 is connected to the bottom of the cylindrical groove 83.

[0043] Specifically, a plurality of sliding grooves 82 are installed in the interior of the fixed column 8 for sliding movement. When the patient has not yet laid on the medical bed 5, the upper ends of the plurality of lifting columns 84 are simultaneously against the lower side of the arc block 73. At this time, the annular spring 85 at the lower end of the lifting column 84 is in a compressed state. Due to the annular arrangement of the plurality of lifting columns 84 and the restoring force of the annular spring 85, the connecting column 74 can be kept in a vertical state, that is, the rotating shaft 75 does not rotate, and the angle of the top plate 7 does not change. When the patient undergoes stone crushing, the top plate 7 has rotated to adapt to different human bodies, that is, the horizontal height of some positions of the top plate 7 increases, and the horizontal height of some positions decreases. The position where the horizontal height increases will allow the corresponding annular spring 85 to rebound from the compressed state, so that the top end of the corresponding lifting column 84 is always in contact with the lower side of the arc block 73, and the position where the horizontal height decreases will allow the corresponding annular spring 85 to continue to be compressed, so that the top end of the corresponding lifting column 84 is always in contact with the lower side of the arc block 73, giving a certain supporting force to the top plate 7 after the angle is changed. The sliding of the plurality of lifting columns 84 can adapt to the skew of the top plate 7 at different angles.

[0044] Embodiment 2

[0045] like Figure 8-9As shown, compared with Example 1, another implementation of the present invention is: an arc head 841 is fixedly installed on the upper end of the lifting column 84, a piston 842 is fixedly installed on the outer side of the lower end of the lifting column 84, the piston 842 is slidably installed inside the cylindrical groove 83, the upper end of the annular spring 85 is fixedly connected to the lower side of the piston 842, and an air seal 831 is fixedly installed on the inner top of the cylindrical groove 83, and the air seal 831 is located on the outer side of the middle section of the lifting column 84.

[0046] A connecting groove 87 and an annular air inlet groove 86 are provided below the cylindrical groove 83 . The cylindrical groove 83 , the lifting column 84 and the annular air inlet groove 86 are connected. The annular air inlet groove 86 is supplied with air through an external air supply device. Air pressure detection modules are evenly distributed inside the annular air inlet groove 86 .

[0047] Specifically, when the multiple annular springs 85 are compressed to different degrees, the top plate 7 maintains a certain angle change due to the weight of the patient to adapt to the body shape of different patients, so that the patient can be in a comfortable posture to cooperate with the stone crushing. The gas input of the air supply device makes the annular air inlet groove 86, the multiple connecting grooves 87 and the bottom of the cylindrical groove 83 filled with air, and the air inside the cylindrical groove 83 will be blocked by the piston 842. The different compression states of the annular springs 85 will make the piston 842 at different heights inside the corresponding cylindrical groove 83, but the gas input will make the bottom ends of all cylindrical grooves 83 filled with air. The internal air pressure at this time is monitored by the air pressure detection module evenly distributed inside the annular air inlet groove 86. When the air pressure reaches the set value, the annular air inlet groove 86, the multiple connecting grooves 87 and the cylindrical groove 83 maintain this air pressure. At this time, it will further support the multiple lifting columns 84 to prevent the patient from changing position, thereby affecting the stone crushing effect.

[0048] Working principle: In the urological stone crushing operation, extracorporeal lithotripsy is used. First, the patient is asked to lie or lie prone on the medical bed 5. Because the stone crushing time is long, in order to avoid the human body from being in contact with the medical bed 5 for too long and causing overheating reaction and patient stress, a ventilation groove 6 is opened on the medical bed 5. Then, the detection head 2 uses X-ray or ultrasonic imaging technology to accurately locate the position of the stone, and then the human body posture is adjusted so that the stone position is aligned with the area where the ultrasonic head 3 can act. In order to keep the human body posture longer without deformation, the human body needs to maintain a comfortable posture. After the stone position is aligned, the human body has contacted the positioning component 4, and the human skin is in contact with the top plate 7. The rotating shaft 75 arranged under the top plate 7 can rotate inside the component column 9 to adapt to the human body posture at this time, so that the patient can maintain the posture in a comfortable state. Then, the ultrasonic head 3 is driven by electricity. The wave head 3 emits ultrasonic waves to crush the stones. After the stones are crushed, they can be discharged through the patient's urethra. When the patient has crushed the stones, he maintains a comfortable human posture. At this time, the rotating shaft 75 has rotated inside the circular shaft groove 91. In order to prevent the top plate 7 from rotating again, affecting the stone position and reducing the stone crushing efficiency, the telescopic motor 92 drives the telescopic column 93 to move upward until the arc bottom plate 95 is in close contact with the bottom of the rotating shaft 75 at this time, that is, the arc surface of the arc bottom plate 95 is against the bottom surface of the rotating shaft 75, so that the rotating shaft 75 no longer rotates easily, and the arc surface of the arc bottom plate 95 is roughly arranged, which further increases the friction of the rotating shaft 75, further avoids the rotating shaft 75 from rotating again, maintains the human posture, and is beneficial to the crushing of urological stones. The rise of the arc bottom plate 95 can be a spiral rise method, which can be more precise.

[0049] The fixed column 8 is internally slidably installed with a plurality of sliding grooves 82. When the patient has not yet laid on the medical bed 5, the upper ends of the plurality of lifting columns 84 are simultaneously against the lower side of the arc block 73. At this time, the annular spring 85 at the lower end of the lifting column 84 is in a compressed state. Due to the annular arrangement of the plurality of lifting columns 84 and the restoring force of the annular spring 85, the connecting column 74 can be kept in a vertical state, that is, the rotating shaft 75 does not rotate, and the angle of the top plate 7 does not change. When the patient undergoes stone crushing, the top plate 7 has rotated to adapt to different human bodies, that is, the horizontal height of some positions of the top plate 7 increases, and the horizontal height of some positions decreases. The position with increased horizontal height will allow the corresponding annular spring 85 to rebound from the compressed state, so that the top end of the corresponding lifting column 84 is always in contact with the lower side of the arc block 73, and the position with decreased horizontal height will allow the corresponding annular spring 85 to continue to be compressed, so that the top end of the corresponding lifting column 84 is always in contact with the lower side of the arc block 73, giving a certain supporting force to the top plate 7 after the angle is changed. The sliding of the plurality of lifting columns 84 can adapt to the skew of the top plate 7 at different angles.
