Abstract
Description
Technical Field
[0001] This invention relates to the field of urological surgery, specifically to a clinical urological stone removal device. Background Technology
[0002] The Department of Urology is a hospital department that mainly diagnoses and treats diseases of the "surgical" part of the urinary system. It mainly treats various urological diseases, among which urological stones are one of the most common urological diseases, ranking first among urology inpatients. Stones can be found in any part of the kidney, bladder, ureter, and urethra.
[0003] In actual treatment, the stones are usually first broken up using shock waves from a lithotripsy device. Then, the stones are guided into the urethra by the vibration of the main and auxiliary vibrators of an external vibratory stone expulsion machine. The stones are then naturally expelled with the flushing force of the patient's own urine. However, if the stones are large or become lodged, causing obstruction and pain, medical staff often rely on subjective observation to judge the degree of pain, which can lead to delayed or premature judgment. If a delayed judgment occurs and vibration stone expulsion continues, it will increase local tissue pressure, induce mucosal damage, and may aggravate spasms. If stone expulsion is interrupted too early, it will affect the efficacy. Furthermore, the intensity of subsequent secondary lithotripsy cannot be adaptively adjusted based on the initial treatment. If the intensity of the secondary lithotripsy is too high, it will cause patient discomfort; if the intensity is insufficient, it will affect the efficacy and efficiency of the secondary treatment, thus impacting the treatment effect and progress. Therefore, we propose a clinical stone expulsion device for urology. Summary of the Invention

A trigger component automatically adjusts the trigger threshold for detecting the patient's grip strength based on their initial grip strength, allowing for different thresholds to be adjusted for different patients, thus improving applicability. Stone expulsion automatically stops when the detected grip strength reaches the trigger threshold to prevent further stone expulsion, which could increase local tissue pressure, induce mucosal damage, or exacerbate spasms. The control component adjusts the sensitivity of the patient's grip strength based on the detection component's measurement. If the amplitude exceeds the trigger threshold of the triggering component, the intensity of the secondary lithotripsy can be adaptively adjusted. This adjustment is based on the patient's condition during the first stone expulsion, preventing excessive intensity from causing discomfort or insufficient intensity from affecting the stone expulsion treatment. Through the auxiliary component, the vibration frequency during stone expulsion can be adaptively adjusted according to the intensity of the lithotripsy to improve the treatment effect and patient comfort. During the second stone expulsion, the vibration frequency can be further adjusted according to the patient's grip strength to enhance the stone expulsion effect. Attached Figure Description

[0032] 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.
[0033] Example 1
[0034] Please see Figures 1 to 10 The present invention provides a technical solution: a urological clinical stone expulsion device, comprising: a bed body 11 and a control body 12, wherein a stone crushing component 13 and a main vibrator 14 are provided on one side of the bed body 11;
[0035] It also includes: detection component 2, which is set on the upper side of the bed 11. The detection component 2 detects the patient's pain during stone expulsion based on the patient's grip strength.
[0036] Trigger component 3 is located on one side of the bed 11. Trigger component 3 automatically adjusts the trigger threshold of the detection component 2 for detecting the patient's grip force based on the initial patient grip force, and automatically stops stone expulsion when the trigger threshold is reached.
[0037] The control component 4 is located on one side of the trigger component 3. The control component 4 adaptively adjusts the secondary lithotripsy intensity of the lithotripsy component 13 according to the patient's grip force detected by the detection component 2 and the extent to which it exceeds the trigger threshold of the trigger component 3.
[0038] The auxiliary component 5 is located on one side of the trigger component 3. The auxiliary component 5 adaptively adjusts the vibration frequency during stone expulsion according to the stone crushing intensity of the stone crushing component 13, and further adjusts the vibration frequency during secondary stone expulsion according to the patient's gripping force.
[0039] During treatment, the patient lies on bed 11. The lithotripsy device's lithotripsy component 13 uses shock waves to break up the stones. The auxiliary vibrator of the extracorporeal vibration lithotripsy machine generates horizontal simple harmonic waves through a simple harmonic exciter. This causes the kidney or ureteral stones to create gaps between themselves and the cavity due to their own inertia, promoting stone dispersal and expanding the sliding space, thus suspending the stones in the liquid. The main vibrator 14 generates a high-energy driving force, using axial simple harmonic waves within a comfortable range for the human body to propel the stones forward. Under their own inertia, the stones slide along the cavity axis. The fluid dynamics effect generated by the vibration enhances urine flow, forming eddies that help move the stones. Combined with the adjustable angle of bed 11, gravity assists in guiding the stones towards the direction of expulsion, thus performing stone expulsion treatment. During the treatment, the detection component 2 can detect the patient's pain during stone expulsion based on their grip strength and improve the patient's body stability. The trigger component 3 can automatically adjust the detection component 2 based on the patient's initial grip strength. The system measures the trigger threshold of the patient's grip strength, allowing for adjustments based on individual patient needs to improve applicability. When the grip strength detected by the detection component 2 reaches the trigger threshold, stone removal automatically stops to prevent further stone removal, which could increase local tissue pressure, induce mucosal damage, or exacerbate spasms. The control component 4 adaptively adjusts the secondary stone-breaking intensity of the lithotripsy component 13 based on the patient's grip strength detected by the detection component 2 and its exceeding the trigger threshold of the trigger component 3. This allows for adaptive adjustment of the secondary stone-breaking intensity based on the patient's condition during the initial stone removal, preventing excessive intensity that could cause discomfort or insufficient intensity that could hinder treatment. The auxiliary component 5 adaptively adjusts the vibration frequency during stone removal based on the stone-breaking intensity of the lithotripsy component 13, improving treatment effectiveness and patient comfort. During the second stone removal, the vibration frequency can be further adjusted based on the patient's grip strength to enhance the stone removal effect.
[0040] The detection component 2 includes a handle 21 fixedly connected to both sides of the bed 11. A pressure member 22 is provided on the outer side of the handle 21. A mounting groove adapted to the pressure member 22 is provided on the outer side of the handle 21. The pressure member 22 is set in the mounting groove. A pressure sensor 23 is provided on the inner side of the mounting groove of the handle 21. The pressure member 22 abuts against the pressure sensor 23.
[0041] During treatment, after lying on the bed 11, the patient can hold the handles 21 on both sides with both hands. The pressure force exerted by the hand on the pressure sensor 23 by the pressure holding member 22 can detect the patient's grip strength. If the stone is large or the obstruction is aggravated during stone expulsion, it will cause pain and discomfort to the patient, which will increase the patient's grip strength on the handles 21. By holding the handles 21, the patient can also improve the stability of the body.
[0042] The triggering component 3 includes a housing 31 disposed on the lower side of the bed 11. The housing 31 is fixedly connected to one side of the support on the lower side of the bed 11. A first electromagnetic block 32 is fixedly connected to the inner side of the housing 31. The first electromagnetic block 32 is electrically connected to the pressure sensor 23. A first slider 33 and a second slider 34 are slidably disposed on the inner side of the housing 31. A first guide groove adapted to the first slider 33 and the second slider 34 is respectively disposed at the bottom of the inner side of the housing 31. The first slider 33 and the second slider 34 are slidably disposed along the first guide grooves on both sides, which can guide and limit the movement of the first slider 33 and the second slider 34. The first slider 33 and the second slider 34 are respectively located on both sides of the first electromagnetic block 32. A first magnetic block 35 is fixedly connected to the side of the first slider 33 and the second slider 34 closest to the first electromagnetic block 32. The first magnetic block 35 repels the first electromagnetic block 32. A first spring 36 fixedly connected to the inner wall of the housing 31 is fixedly connected to the other side of the first slider 33 and the second slider 34.
[0043] A first rack 37 is fixedly connected to one side of the first slider 33. A first gear 38 is meshed with the lower side of the first rack 37. A second gear 39 is fixedly connected to one side of the first gear 38. The diameter of the first gear 38 is smaller than the diameter of the second gear 39. A support rod 310 is rotatably mounted on the middle of the first gear 38 and the second gear 39 via a bearing. The lower end of the support rod 310 is fixedly connected to the bottom inner side of the box body 31. A second rack 311 is meshed with the lower side of the second gear 39 and slidably mounted on the bottom inner side of the box body 31. A second guide groove adapted to the second rack 311 is provided on the bottom inner side of the box body 31. The rack 311 is slidably disposed along the second guide groove; one end of the second rack 311 is fixedly connected to a connector 312 that is slidably disposed with the bottom inner side of the box 31, and the bottom inner side of the box 31 is provided with a third guide groove that is adapted to the connector 312, and the connector 312 is slidably disposed along the third guide groove; a first switch 314 is provided on the side of the connector 312 near the second slider 34, and a pressure block 313 is fixedly connected on one side of the second slider 34, and the side of the pressure block 313 near the first switch 314 is provided with an arc-shaped end face so as to abut against the first switch 314. Initially, the pressure block 313 abuts against the first switch 314.
[0044] When the patient initially grips the lever 21, the pressure sensor 23 detects that a larger initial grip force results in a larger pressure detected by the pressure sensor 23, strengthening the output signal. This causes a stronger repulsive force between the first electromagnetic block 32 and the first magnetic block 35, resulting in a larger movement of the first slider 33 away from the first electromagnetic block 32. The first spring 36 is compressed, and the movement of the first slider 33 drives the synchronous movement of the first rack 37, causing the first gear 38 to rotate. This, in turn, drives the second gear 39 to rotate, causing the second rack 311, connector 312, and first switch 314 to move away from the support rod 310. This allows for adaptive adjustment of the position of the first switch 314 and the triggering threshold of the pressure block 313 based on the patient's initial grip force, thus improving the applicability of treatment for different patients.
[0045] A first locking element 315 is provided on one side of the first slider 33. The first locking element 315 includes a first housing 3151. A locking tooth block 3153 is slidably provided inside the first housing 3151. A second electromagnetic block 3152 that attracts the locking tooth block 3153 is fixedly connected inside the first housing 3151. A second spring 3154 that is fixedly connected to the inner wall of the first housing 3151 is symmetrically fixedly connected inside the locking tooth block 3153. A locking tooth rod 316 that cooperates with the locking tooth block 3153 is fixedly connected to the bottom of the inner side of the box 31. The first housing 3151 of the first locking element 315 is fixedly connected to the first slider 33.
[0046] Initially, the second electromagnetic block 3152 is energized, attracting the locking block 3153, causing it to detach from the locking rod 316. The second spring 3154 is compressed to avoid obstructing the movement of the first slider 33. After the pressure sensor 23 detects the patient's initial gripping force, the first slider 33 moves to adjust the trigger position of the first switch 314. Then, the second electromagnetic block 3152 is de-energized. Under the elastic force of the second spring 3154, the locking block 3153 engages and is fixed with the locking rod 316, maintaining the adjusted position. The location of switch 314 is such that during the stone expulsion process, if the stone is large and the impaction is aggravated, causing obstruction and pain for the patient, the patient's grip on the handle 21 will increase. Through the detection of pressure sensor 23, the magnetism of the first electromagnetic block 32 can be enhanced. When the second slider 34 moves away from the first electromagnetic block 32, causing the pressure block 313 to contact the first switch 314, it indicates that the trigger threshold has been reached. At this time, the stone expulsion will be stopped to prevent the stone expulsion from continuing, which would lead to an increase in local tissue pressure, induce mucosal damage, and aggravate spasms.
[0047] The control component 4 includes a mounting component 41 slidably disposed on the upper side of the connector 312. A fourth guide groove adapted to the mounting component 41 is provided on the upper side of the connector 312, and the mounting component 41 is slidably disposed along the fourth guide groove. A telescopic end of an electric push rod 42 is fixedly connected to one side of the mounting component 41. The electric push rod 42 is fixedly connected to the upper side of the connector 312. A metal strip 43 is fixedly connected to the mounting component 41. A sliding piece 44 is slidably disposed on the outer side of the metal strip 43. The metal strip 43 is electrically connected to the crushed stone component 13 through the sliding piece 44. The resistance value of the metal strip 43 on the side of the sliding piece 44 closest to the electric push rod 42 is connected to the circuit. A connecting rod 45 is fixedly connected to the upper side and slidably disposed with the mounting member 41. A fifth guide groove adapted to the connecting rod 45 is provided on the upper side of the mounting member 41, and the connecting rod 45 is slidably disposed along the fifth guide groove. One end of the connecting rod 45 is located on the side of the second slider 34 away from the first electromagnetic block 32. A second switch 46 is provided on the side of the connecting member 312 near the connecting rod 45. The end face of the connecting rod 45 near the second switch 46 is set as arc-shaped so as to abut against the second switch 46. Initially, the connecting rod 45 abuts against the second switch 46. A third spring 47 is fixedly connected to one side of the connecting rod 45 and fixedly connected to the mounting member 41.
[0048] A second housing 48 is fixedly connected to one side of the connecting rod 45. A helical tooth block 49 is slidably arranged inside the second housing 48. A third electromagnetic block 410 that attracts the helical tooth block 49 is fixedly connected to the inside of the second housing 48. A fourth spring 411 that is fixedly connected to the inner wall of the second housing 48 is symmetrically fixedly connected to the inside of the helical tooth block 49. A helical tooth rod 412 that cooperates with the helical tooth block 49 is fixedly connected to the upper side of the mounting part 41.
[0049] During the stone expulsion process, when the movement of the second slider 34 causes the pressure block 313 to contact the first switch 314, the second slider 34 can push one end of the connecting rod 45 and drive the connecting rod 45 to move. This causes the connecting rod 45 to move the sliding plate 44 closer to the electric push rod 42, compressing the third spring 47. If the distance that the second slider 34 pushes the connecting rod 45 and the sliding plate 44 closer to the electric push rod 42 is large, it indicates that the patient experiences strong pain and discomfort during stone expulsion, suggesting that the stone is large and the impaction is aggravated, causing obstructed stone expulsion. At this time, the metal strip 43 will... The connection resistance value is relatively small. By controlling the main body 12, the intensity of the shock wave of the lithotripsy component 13 during secondary lithotripsy can be relatively large, thereby improving the intensity of secondary lithotripsy and thus improving the effect of secondary stone expulsion. This reduces the impact of large stones and aggravated impaction during the first stone expulsion, which can lead to poor stone expulsion and improve the treatment effect. Conversely, if the distance that the second slider 34 pushes the connecting rod 45 and the slider 44 to move closer to the electric push rod 42 is small, the intensity of secondary lithotripsy can be relatively small, thereby improving patient comfort and avoiding unnecessary large lithotripsy intensity, which could cause patient discomfort.
[0050] When the second slider 34 pushes the connecting rod 45 to move, the helical tooth block 49 can move along the surface of the helical tooth rod 412. Then, through the reverse blocking effect of the helical tooth rod 412 on the helical tooth block 49, the reverse movement of the helical tooth block 49 can be restricted to reset, maintaining the current position of the connecting rod 45 and the slide plate 44 driven by the second slider 34 after adjustment. Then, the extension end of the electric push rod 42 drives the mounting part 41 to move closer to the support rod 310. When the connecting rod 45 moves to the point of contacting the second switch 46, it will control the electric push rod 42 to stop working. At this time, when the movement of the second slider 34 causes the pressure block 313 to contact the first switch 314 again, the second slider 34 can push the connecting rod 45 to move again for the adjustment of the crushing strength three times (if a third adjustment is required).
[0051] Example 2
[0052] The auxiliary component 5 includes a fourth electromagnetic block 51 fixedly connected to the inside of the box 31. The fourth electromagnetic block 51 is electrically connected to the stone crushing component 13. A third slider 52 and a fourth slider 58 are slidably arranged inside the box 31. A sixth guide groove adapted to the third slider 52 and the fourth slider 58 is provided at the bottom of the inside of the box 31. The third slider 52 and the fourth slider 58 are slidably arranged along the sixth guide groove. A second magnetic block 53 that repels the fourth electromagnetic block 51 is fixedly connected to one side of the third slider 52. A fifth spring 54 fixedly connected to the inner wall of the box 31 is fixedly connected to the other side of the third slider 52. A third rack 56 that slides at the bottom of the inside of the box 31 is fixedly connected to one side of the third slider 52. A speed regulator 57 is provided inside the box 31. The speed regulator 57 is electrically connected to the main vibrator 14 and the auxiliary vibrator of the external vibrating stone expelling machine. A gear component 55 is fixedly connected to the knob of the speed regulator 57. The gear component 55 meshes with the third rack 56.
[0053] When the stone-crushing strength of the stone-crushing component 13 is relatively high, the magnetism of the fourth electromagnetic block 51 will be stronger, resulting in a greater repulsive effect on the second magnetic block 53. This causes the third slider 52 to move the third rack 56 away from the fourth electromagnetic block 51 by a greater distance. The fifth spring 54 is compressed, resulting in a relatively large rotation amplitude of the knobs of the gear component 55 and the speed regulator 57. Consequently, through the speed regulator 57, the vibration frequency of the main vibrator 14 and the auxiliary vibrator of the stone-expelling machine is relatively low. This is to adapt to the situation where the stone-crushing strength is high, the broken stones are relatively small, and a relatively low vibration frequency can be used for stone expulsion, improving the patient's comfort during stone expulsion.
[0054] A stopper 510 is provided on one side of the third slider 52 and is slidably disposed on the bottom inner side of the box 31. A seventh guide groove adapted to the stopper 510 is provided on the bottom inner side of the box 31. The stopper 510 is slidably disposed along the seventh guide groove. One end of the stopper 510 is located on the side of the third slider 52 near the fourth electromagnetic block 51. A fifth electromagnetic block 59 is fixedly connected to the inner side of the fourth slider 58. Initially, the fifth electromagnetic block 59 is energized to generate an attraction effect on the second magnetic block 53, so that the fourth slider 58 is located on one side of the third slider 52. A third switch 516 is provided on one side of the connector 312. The third switch 516 is electrically connected to the fifth electromagnetic block 59 and the pressure sensor 23.
[0055] The abutment 510 has a second locking member 511 and a third locking member 512 on both sides, and a fourth locking member 513 on one side of the fourth slider 58. The structures of the second locking member 511, the third locking member 512 and the fourth locking member 513 are the same as those of the first locking member 315. The first housing 3151 of the second locking member 511 and the third locking member 512 are fixedly connected to both sides of the abutment 510, and the first housing 3151 of the fourth locking member 513 is fixedly connected to one side of the fourth slider 58. A toothed groove 515 is provided on one side of the third slider 52. A toothed rod 514 is fixedly connected to the bottom of the inner side of the box 31. The toothed rod 514 and the toothed groove 515 cooperate with the toothed block 3153.
[0056] Initially, the second electromagnetic block 3152 of the second locking member 511 is de-energized, and the locking tooth block 3153 of the second locking member 511 is engaged and fixed with the tooth groove 515. The second electromagnetic blocks 3152 of the third locking member 512 and the fourth locking member 513 are energized. The movement of the third slider 52 can drive the synchronous movement of the stop member 510 and the fourth slider 58. Then, the second electromagnetic block 3152 of the third locking member 512 is de-energized, so that the locking tooth block 3153 of the third locking member 512 engages with the toothed member 514. The locking mechanism is engaged and fixed, maintaining the current position of the blocking member 510. The second electromagnetic block 3152 of the second locking member 511 is energized, causing the locking tooth block 3153 of the second locking member 511 to disengage from the tooth groove 515. During secondary stone crushing, the increased crushing strength will cause the third slider 52 and the fourth slider 58 to move away from the blocking member 510. Then, the second electromagnetic block 3152 of the fourth locking member 513 is de-energized, causing the locking tooth block 3153 of the fourth locking member 513 to engage and be fixed with the toothed member 514.
[0057] During the secondary stone removal process, when the pressure block 313 contacts the third switch 516, it controls the fifth electromagnetic block 59 to connect with the pressure sensor 23. The circuit uses current-shunting negative feedback; when the gripping force detected by the pressure sensor 23 increases, the output signal of the pressure sensor 23 strengthens. The control circuit recognizes this as increased pain and reduces the driving current of the fifth electromagnetic block 59, thus reducing the magnetism of the fifth electromagnetic block 59 and decreasing its attraction to the second magnetic block 53. Under the elastic force of the fifth spring 54, the third slider 52 moves away from the fourth slider 58. This allows the speed regulator 57 to increase the vibration frequency of the stone removal machine, appropriately increasing the vibration frequency during stone removal without exceeding the trigger threshold of the first switch 314, thereby improving the stone removal effect. If subsequent pressure... If block 313 does not contact the first switch 314, it indicates that the vibration frequency increase is effective within the allowable range, improving the stone expulsion effect. Conversely, if the adjusted block 313 contacts the first switch 314, the second slider 34 can, based on the secondary stone crushing intensity adjustment through the control component 4, drive the connecting rod 45 and the sliding plate 44 to move again, adjusting the tertiary stone crushing intensity to prevent further stone expulsion from aggravating pain and spasms, causing tissue and mucosal damage. Furthermore, after the third switch 516 is triggered, the vibration frequency during stone expulsion is further adjusted. Through the setting of the blocking component 510, the third slider 52 can be blocked to prevent the third slider 52 from moving too far away from the fourth slider 58, resulting in an excessive increase in vibration frequency, which could cause or aggravate the patient's pain and discomfort.
