Description

Technical Field

[0001] This utility model specifically relates to a vibration-assisted stone expulsion device for ureteroscopic lithotripsy. Background Technology

[0002] Kidney stones are a common disease in urology, accounting for as much as 39.33% of hospitalized cases. Kidney stones are formed in the kidneys by some components in the urine, often causing urinary symptoms. The formation of kidney stones involves various factors, such as abnormal human metabolic products, increased urine concentration, urinary tract system factors, and corresponding drug factors.

[0003] There are various treatment options for kidney stones, including medication, extracorporeal shock wave lithotripsy, ureteroscopic holmium laser lithotripsy, percutaneous nephrolithotomy with holmium laser lithotripsy, and open surgery. Among these, ureteroscopic holmium laser lithotripsy is particularly suitable for patients with complex stone locations, large or numerous stones, or those who do not respond well to other treatments, due to its minimally invasive nature, high precision, wide range of indications, high safety, and ease of repeat surgery.

[0004] With advancements in ureteroscopic holmium laser lithotripsy, surgical techniques and auxiliary tools have become increasingly sophisticated, and the scope of application has gradually expanded. However, the problem of residual stones after surgery remains a significant concern, with an incidence rate typically ranging from 10% to 30%. This risk is particularly high for stones located in the lower calyx of the kidney or complex stones. These residual stones can trigger a series of complications, such as urinary tract irritation, increased risk of urinary tract infection, stone recurrence, urinary tract obstruction, and even acute renal failure. Some patients require a second surgery, which not only affects their quality of life but may also prolong the treatment period and increase the medical burden.

[0005] In ureteroscopic holmium laser lithotripsy, improving the stone clearance rate is crucial. Currently, the mainstream method is to use a holmium laser to fragment or pulverize the stones, and then remove the fragments using a stone retrieval basket or a negative pressure ureteral sheath. However, due to the limitations of kidney anatomy (angle between the renal pelvis and infundibulum, length of the infundibulum of the lower calyx, width of the infundibulum neck of the lower calyx, height of the renal pelvis and lower calyx, and degree of hydronephrosis) and the characteristics of the stones (stone load, location, density, etc.), complete removal is not easy. Therefore, exploring and applying new technologies to improve the stone clearance rate is particularly urgent.

[0006] Based on this, we designed a novel device specifically for intraoperative ureteroscopic holmium laser lithotripsy to improve stone clearance rate. This method can not only adjust the stone position through vibration to reduce the difficulty of lithotripsy, but also effectively promote the expulsion of fragments through mechanisms such as enhancing hydrodynamics, generating eddies, weakening boundary layer effects, and promoting fluid mixing. This innovative strategy is expected to bring new breakthroughs to the treatment of stones in urology. Utility Model Content

[0007] The main technical objective of this invention is to solve the problems mentioned in the background art, such as the high residual stone rate and the inconvenience of removing some fragments during ureteroscopic holmium laser lithotripsy.

[0008] To address the aforementioned technical problems, a vibration-assisted stone-expelling device for ureteroscopic lithotripsy was designed. This is achieved through the following technical solution: A vibration-assisted stone-expelling device for kidney stones includes a mattress, a position adjustment unit, a back vibration unit, and an abdominal vibration unit. The mattress is placed on the operating table, and the position adjustment unit is placed on the mattress, supporting the patient and maintaining their position during the stone-expelling process. The back vibration unit, used for vibration of the patient's lower back, is placed on the mattress, and the distance between the back vibration unit and the patient's body is adjustable. The abdominal vibration unit is placed on the mattress via a mounting strap, which is movably positioned on the patient's abdomen. The abdominal vibration unit vibrates the patient's abdomen, and the positions of the abdominal vibration unit and the mounting strap on the mattress are controllably adjustable via a position adjustment component.

[0009] In a preferred embodiment of the present invention, the mattress includes a support layer and a pressure-reducing layer. The pressure-reducing layer is disposed on the support layer. When the patient lies on the pressure-reducing layer, the pressure-reducing layer improves the patient's comfort. The support layer ensures the strength of the entire mattress. The back vibration part and the abdominal vibration part are installed on the support layer to prevent energy loss during vibration.

[0010] In a preferred embodiment of the present invention, an airbag mounting cavity for mounting the body position adjustment unit and a vibration unit mounting cavity for mounting the back vibration unit are provided on the decompression layer. The airbag mounting cavity is provided on both sides of the vibration unit mounting cavity, and the provision of the vibration unit mounting cavity facilitates the installation of the back vibration unit.

[0011] In a preferred embodiment of the present invention, the body position adjustment unit includes an airbag assembly, which comprises multiple strip-shaped airbags stacked together and connected to each other. This arrangement facilitates lifting the patient's waist through the strip-shaped airbags, adjusting the fit between the vibrating plate and the patient, and facilitating operation.

[0012] In a preferred embodiment of the present invention, the strip-shaped airbag is closed in the middle, forming two closed air chambers. The air chambers are connected to an external air pump through an air guide tube. This configuration facilitates the adjustment of multiple patient positions and makes it easy to maintain the adjusted position.

[0013] In a preferred embodiment of the present invention, multiple airbag assemblies are provided on the mattress, with one airbag assembly installed in each airbag installation cavity of the mattress. This arrangement facilitates the adjustment of the patient's body position.

[0014] In a preferred embodiment of the present invention, the back vibration unit includes a back vibration shell, a vibration motor, and a motor mounting plate. The back vibration shell is detachably mounted on the support layer of the mattress, corresponding to the position of the vibration unit mounting cavity on the pressure relief layer. There are multiple vibration motors, which are mounted on the motor mounting plate via a first linear slide rail pair and connected to the vibration shell. The back vibration unit facilitates the easier discharge of renal pelvis and posterior renal calyx stones with the flushing fluid.

[0015] In a preferred embodiment of the present invention, one end of the vibration motor passes through the back vibration shell, and a vibration plate is detachably installed at the end of the vibration motor that extends out of the back vibration shell. The vibration plate is in contact with the patient's body. This arrangement facilitates the improvement of the vibration effect and makes it easier to expel the stones.

[0016] In a preferred embodiment of the present invention, an adjustment airbag is provided at the bottom of the vibration motor. The adjustment airbag is connected to an external air pump through an air guide tube. This arrangement facilitates the adjustment of the height of the vibration plate, so that the vibration plate on the vibration motor fits closely to the patient's body, thereby improving the vibration effect.

[0017] In a preferred embodiment of the present invention, the abdominal vibration unit includes an abdominal vibration housing for mounting a vibration motor. The abdominal vibration housing is mounted on a mounting belt, one end of which is connected to a position adjustment component. The position adjustment component is mounted on a mattress. The mounting belt adjusts the position of the abdominal vibration unit relative to the mattress via a second linear slide rail pair in the position adjustment component. This arrangement facilitates adjustment of the vibration position, and the abdominal vibration makes it easier for stones in the anterior renal calyces to be expelled with the flushing fluid.

[0018] The advantages of this utility model compared with the prior art are: This invention uses a mattress as the carrier of the entire device. During use, the mattress is simply placed directly on the operating table, making installation easy. Simultaneously, the patient's position is adjusted and maintained via a positioning unit, while vibrations are applied to the area between the patient's lower back and lateral abdomen using back and abdominal vibration units. This design effectively solves the problem of kidney stones (especially high-load and complex kidney stones) being difficult to expel with the flushing fluid by improving fluid dynamics and other methods.

Detailed Implementation

[0020] The following will refer to the appendix in the embodiments of this utility model. Figure 1-9 The technical solutions in the embodiments of this utility model will be described in detail below. Example

[0021] like Figure 1 and 9 As shown, a vibration-assisted stone removal device for ureteroscopic lithotripsy includes a mattress 1, a body position adjustment unit 2, a back vibration unit 3, and an abdominal vibration unit 4, wherein the body position adjustment unit 2, the back vibration unit 3, and the abdominal vibration unit 4 are all installed on the mattress 1.

[0022] The main function of mattress 1 is to serve as a carrier for the installation of the entire device; mattress 1 can be placed directly on the operating table.

[0023] The main function of the position adjustment unit 2 is to assist the patient by elevating the patient's waist or maintaining and fixing the patient's position to facilitate the vibration and expulsion of stones.

[0024] The main function of the back vibration section 3 and the abdominal vibration section 4 is to vibrate the anterior and posterior sides of the patient near the kidneys. Vibration can lead to an increase in local fluid velocity. In such a narrow space as the collecting system, the increase in flow velocity means an increase in fluid dynamics. This helps to overcome the friction between the stone particles and the surrounding tissues, making it easier for the stones to move with the flow of urine and facilitating the excretion of kidney stones.

[0025] like Figure 1 and2 As shown, the mattress 1 includes a support layer 11 and a pressure-reducing layer 12. The size of the support layer 11 is the same as that of the pressure-reducing layer 12. The pressure-reducing layer 12 is fixed to the upper surface of the support layer 11 with glue.

[0026] The support layer 11 and the decompression layer 12 have rectangular cross-sections, and their overall dimensions correspond to the dimensions of the operating table. The support layer 11 is made of a 2cm thick wooden board and mainly serves as a support. The decompression layer 12 is made of high-density sponge. The patient lies on the support layer 11. The support layer 11 and the decompression layer 12 are connected together by glue and wrapped with a layer of leather that is easy to wipe, disinfect and clean, forming the mattress 1.

[0027] To facilitate the installation of the back vibration unit 3, a rectangular groove is recessed in the middle of the decompression layer 12. This groove is named the vibration unit installation cavity 14. There are two vibration unit installation cavities 14 in the length direction of the decompression layer 12. The two vibration unit installation cavities 14 are distributed opposite each other. After the patient lies on the mattress 1, the position of the patient's kidney corresponds to the vibration unit installation cavity 14.

[0028] To facilitate the installation of the body position adjustment unit 2, a rectangular groove is provided on each side of the vibration part mounting cavity 14 along the length direction on the support layer 11. This groove is named the airbag mounting cavity 13. The airbag assembly 21 in the body position adjustment unit 2 is installed in this airbag mounting cavity 13.

[0029] Definition: In this embodiment, with the patient as a reference, the direction of the mattress 1 corresponding to the patient's height is the length direction, the direction corresponding to the patient's head is the head end, the direction corresponding to the feet is the tail end, the direction from the ground to the patient is the upper end, and the direction from the patient to the ground is the lower end.

[0030] like Figure 1 , 3 As shown in Figure 8, the body position adjustment unit 2 includes multiple airbag assemblies 21, which are located in the airbag mounting cavity 13.

[0031] The airbag assembly 21 includes multiple strip-shaped airbags 22. In this embodiment, four strip-shaped airbags 22 are preferred. The cross-section of the strip-shaped airbags 22 is rectangular. The strip-shaped airbags 22 are made of polyurethane (TPU) material. The multiple strip-shaped airbags 22 are interconnected and stacked together to form an airbag assembly 21. The stacking arrangement can better shape the inflated airbag and also increase the height of the airbag assembly 21 during inflation, which is convenient for supporting the patient and for fixing the patient.

[0032] The connection between the strip-shaped airbags 22 is a fixed connection, which can be either a conventional heat-sealing or adhesive bonding. In this embodiment, heat-sealing is preferred.

[0033] After supporting the patient, in order to facilitate maintaining the patient's position, the middle of the strip-shaped airbag 22 is sealed from the middle, that is, the middle of the strip-shaped airbag 22 is isolated into two separate chambers along the length direction. Each chamber is named an air chamber 23. The air chambers 23 on the same side of the airbag assembly 21 are connected separately and connected to an external air pump through the air guide tube 24. By inflating and deflating different air chambers 23 by the air pump, different support and fixation effects are achieved.

[0034] Regarding the use of the body position adjustment unit 2, the airbag components 21 on both sides of the vibration unit mounting cavity 14 can be inflated simultaneously as needed to lift the patient's waist. Alternatively, the air chamber 23 on the outer side of the airbag component 21 can be inflated separately, or the air chambers 23 on the outer and inner sides can be inflated separately to achieve different support effects. The inflation and deflation of the air chambers 23 by the air pump can be controlled separately by a three-way valve.

[0035] like Figure 1 , 4 As shown in Figures 5 and 6, the back vibration unit 3 includes a back vibration housing 31, a vibration motor 32, and a motor mounting plate 33. The back vibration housing 31 is a rectangular hollow plastic box. The main function of the back vibration housing 31 is to serve as a carrier for mounting the vibration motor 32. The motor mounting plate 33 is integrated with the back vibration housing 31, and the vibration motor 32 is movably mounted on the motor mounting plate 33.

[0036] The back vibration shell 31 is a rectangular hollow plastic box. The back vibration shell 31 is placed in the vibration part mounting cavity 14 and fixed to the support layer 11 by screws. The lower end of the back vibration shell 31 is open and closed by a rectangular base plate 34. Six circular through holes are opened at the upper end of the back vibration shell 31. These through holes are named functional holes 35. One end of the vibration motor 32 extends out from the functional holes 35 and comes into contact with the patient.

[0037] The motor mounting plate 33 is a plastic plate with a rectangular cross-section. The vibration motor 32 is movably connected to the motor mounting plate 33. In order to facilitate the movable connection between the vibration motor 32 and the motor mounting plate 33, a first linear slide rail pair 37 is fixed on the motor mounting plate 33 with screws. The slide rail of the first linear slide rail pair 37 is fixed on the motor mounting plate 33.

[0038] The first linear slide rail pair 37 has 6 slide rails on the motor mounting plate 33. The 6 slide rails are fixed in groups of 3 on both sides of the motor mounting plate 33. Each slide rail is fitted with a slider. The vibration motor 32 is fixed to the slider by an "L"-shaped motor mounting clip 39.

[0039] The motor mounting clip 39 is made of metal. The mounting base of the vibration motor 32 is fixed to the vertical plate of the motor mounting clip 39 by screws and connected to the slider. Under the action of the first linear slide rail pair 37, the vibration motor 32 can move along the slide rail, thereby adjusting the interval between itself and the patient.

[0040] Vibration motor 32 is an existing eccentric vibration motor, an existing component, and can be used directly.

[0041] To facilitate adjustment of the gap between the vibration motor 32 and the patient, a rectangular groove is recessed perpendicular to the base plate 34 at the position corresponding to each vibration motor 32 on the surface of the base plate 34, and an adjustment airbag 38 is placed in each groove.

[0042] The adjustment airbag 38 is an inflatable rectangular airbag made of polyurethane (TPU) material. To prevent the adjustment airbag 38 from moving during use, the adjustment airbag 38 is placed in the groove of the base plate 34, and the lower surface of the adjustment airbag 38 is glued to the bottom surface of the groove. The adjustment airbag 38 is connected to an external air pump through the air guide tube 24. The air pump inflates and deflates multiple adjustment airbags 38 to adjust the height of different vibration motors 32.

[0043] To increase the vibration surface, a vibration plate 36 is fixed to one end of each vibration motor 32 that extends out of the functional hole 35 with screws. The vibration plate 36 is a rectangular plastic plate with a screw hole in the middle. The vibration plate 36 is connected to the vibration motor 32 by screws.

[0044] The vibrating plate 36 increases the contact area between the vibrating motor 32 and the patient, thereby improving the vibration effect.

[0045] like Figure 1 , 7 As shown in Figure 9, the abdominal vibration unit 4 includes an abdominal vibration shell 43. There are two sets of abdominal vibration units 4, which correspond to the two back vibration units 3 respectively. The abdominal vibration shell 43 is a hollow plastic box with a rectangular cross-section. To facilitate the abdominal vibration shell 43 to fit the patient, the surface of the abdominal vibration shell 43 that contacts the patient is an arc surface.

[0046] A vibration motor 32 is fixed inside the abdominal vibration shell 43 with screws. In this embodiment, six vibration motors 32 are preferably provided. The six vibration motors 32 are arranged inside the abdominal vibration shell 43. One end of the vibration motor 32 extends out of the abdominal vibration shell 43 and is fixed with a rectangular vibration plate 36 by screws. The vibration plate 36 contacts the patient to increase the vibration area.

[0047] To facilitate the installation of the abdominal vibration unit 4, a position adjustment component 42 is provided on the support layer 11 near the vibration unit mounting cavity 14, and a mounting strap 41 is provided on the position adjustment component 42, and the abdominal vibration shell 43 is fixed on the mounting strap 41.

[0048] The mounting strap 41 is made of nylon braided strap and passes through the lower end of the abdominal vibration shell 43. One end of the mounting strap 41 is fixed to the position adjustment component 42, and the other end is fixed with a buckle 44. The buckle 44 is an existing device that can be used directly.

[0049] Two sets of mounting straps 41 are provided on the mattress 1. The two sets are located at the vibration part mounting cavity 14 on the support layer 11 and are connected to the position adjustment component 42. The two mounting straps 41 are connected by buckles 44, thereby bringing the abdominal vibration part 4 into contact with the patient's abdomen near the kidneys to achieve vibration.

[0050] The position adjustment assembly 42 includes a second linear slide rail pair 45. The slide rail on the second linear slide rail pair 45 is fixed to the support layer 11 by screws. The slider is installed on the slide rail. In order to limit the position of the slider, an "L"-shaped limit card 46 is fixed to each end of the slide rail with screws. The end of the limit card 46 is higher than the slide rail, which can effectively prevent the slider from falling off the slide rail. The slider is a slider with a self-locking function. One end of the mounting belt 41 is fixed to the slider by screws. By adjusting the position of the slider on the slide rail, the position of the mounting belt 41 can be adjusted, thereby realizing the adjustment of the position of the abdominal vibration part 4.

[0051] To facilitate the adjustment of the position of the abdominal vibration unit 4, a plurality of circular mounting holes 47 are spaced apart on the mounting belt 41. A fixing screw 48 is fitted inside the mounting hole 47. The spacing between two adjacent mounting holes 47 is the same as the size of the abdominal vibration housing 43. The fixing screw 48 can restrict the movement, and the position of the abdominal vibration unit 4 on the mounting belt 41 can be adjusted by adjusting the position of the fixing screw 48.

[0052] Regarding the power supply of the vibration motor 32, the vibration motor 32 is connected to an external power source via a plug (not shown in the figure). In order to facilitate the control of the vibration intensity of the vibration motor 32, a controller 15 can be installed on the side of the mattress 1. The controller 15 can adjust the vibration intensity of each vibration motor 32, and can also control the switch of a certain vibration motor 32 individually. In this embodiment, it is preferable that all vibration motors 32 are turned on. Controlling the vibration intensity and switch of a certain motor through the controller 15 is existing technology and will not be described in detail in this embodiment.

[0053] To facilitate doctors' control of the vibration motors 32 inside the back vibration unit 3 and the abdominal vibration unit 4 during use, a control foot pedal 16 is connected to the back vibration unit 3 and the abdominal vibration unit 4. The control foot pedal 16 is equipped with two pedals, which control the on / off of the back vibration unit 3 and the abdominal vibration unit 4 respectively. When in use, doctors can directly step on the control foot pedal 16 to control the on / off of the back vibration unit 3 or the abdominal vibration unit 4, which is convenient to use.

[0054] There are two control foot pedals 16. The back vibration part 3 and the abdominal vibration part 4 on the same side of the mattress 1 are controlled by the same control foot pedal 16.

[0055] In this embodiment, the advantages of the back vibration part 3 and the abdominal vibration part 4 are mainly reflected in the following aspects: 1. Increased fluid velocity: Vibration can increase local fluid velocity. In narrow spaces such as the kidneys, the increased flow velocity means enhanced fluid dynamics, which helps overcome the friction between the stone particles and the surrounding tissues, making it easier for the stones to be expelled with the flushing fluid.

[0056] 2. Generating eddies: Vibration can generate eddies in a fluid, changing the pressure distribution inside the fluid and creating a pressure difference around the stone. This pressure difference helps to move the stone, causing some originally stationary stones to flow with the flushing fluid and be easier to expel.

[0057] 3. Reduce the influence of the boundary layer: During the flow process, a region called the boundary layer is formed near the solid wall, where the fluid velocity is slower, thus affecting the efficiency of stone expulsion. Vibration can reduce the influence of the boundary layer, increase the fluid velocity near the kidney wall, and thus promote the expulsion of stones.

[0058] 4. Promotes fluid mixing: Vibration can also promote fluid mixing and reduce dead zones in the flow. Dead zones are the almost stationary parts of the fluid flow, where stones are difficult to expel. Vibration can reduce these dead zones, making the fluid movement throughout the kidney more uniform and increasing the probability of stone expulsion.

[0059] The usage process of this embodiment is as follows: First, let the patient lie on the mattress 1, then tie the installation strap 41 around the patient's waist, adjust the position of the abdominal vibration part 4, then use the body position adjustment part 2 to restrict the patient's body position as needed, then adjust the back vibration part 3 so that the vibration plate 36 contacts the patient, and then control the vibration motor 32 to open as needed to achieve assisted vibration to expel stones from the patient.

[0060] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
