Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to an auxiliary device for kidney lithotripsy. Background Technology

[0002] The shortage of donor kidneys is currently the biggest obstacle to the successful implementation of kidney transplantation surgery, while expanding the source of donor kidneys and utilizing marginal donor kidneys are effective ways to solve the shortage. With the development of endoscopic urological surgery techniques, through surgical intervention on kidneys with stones, it is possible to bring them up to the standard of healthy donor kidneys. After evaluation and active treatment, they can be used as donor kidneys.

[0003] Currently, when performing surgery on a donor kidney for kidney stones, multiple assistants are required. The assistants must hold the donor kidney and place it in ice-cold saline solution at 0-4°C. They must also insert a flexible ureteroscope sheath into the donor kidney to break up the stones and remove them. The stone breaking process requires a lot of manpower and is prone to frostbite on the assistants' hands. The stone breaking process is also time-consuming and can easily cause kidney damage. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an auxiliary device for kidney lithotripsy, which solves the problems of the need for multiple people to assist in existing kidney lithotripsy and the long time required for lithotripsy.

[0005] To achieve the above objectives, the technical solution of the present invention is as follows: an auxiliary device for kidney lithotripsy includes a frame, a placement mechanism, and a vibration mechanism. The placement mechanism is movably disposed within the frame, and the vibration mechanism is connected to the placement mechanism. In use, the donor kidney is placed on the placement mechanism for lithotripsy surgery, and after the surgery, the vibration mechanism is activated, causing the placement mechanism to vibrate within the frame to expel the lithotripsy stones from the kidney.

[0006] Furthermore, the vibration mechanism includes a cam and a drive assembly for rotating the cam, the cam being in contact with the bottom of the storage platform.

[0007] Furthermore, the drive assembly includes a drive motor, a drive wheel, and a driven wheel.

[0008] Furthermore, the storage mechanism includes a storage platform and a storage component. The storage platform is slidably disposed within the frame and vibrates up and down within the frame under the drive of the vibration mechanism. One end of the storage component is close to the outer edge of the storage platform, and the other end is connected to the side wall of the frame.

[0009] Furthermore, the placement component is an inclined tubular structure or an arc-shaped groove structure, and the lower end of the placement component is connected to the side wall of the frame.

[0010] Furthermore, the frame is provided with a through hole, and a barrier is provided inside the through hole.

[0011] Furthermore, the barrier is composed of several fan-shaped structures whose outer edges are movably connected to the outer edge of the through hole.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

They do not imply that the device or element referred to must have a specific orientation or position, and therefore should not be construed as a limitation of this invention. In the description of this invention, it should be noted that unless otherwise explicitly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] The auxiliary device for kidney stone fragmentation provided in this embodiment, such as... Figures 1-3 As shown, it includes a frame 1, a placement mechanism 2, and a vibration mechanism 3. The placement mechanism 2 is movably disposed within the frame 1, and the vibration mechanism 3 is connected to the placement mechanism 2. In use, the donor kidney is placed on the placement mechanism 2 for lithotripsy surgery, and after the surgery, the vibration mechanism 3 is activated. The vibration mechanism 3 drives the placement mechanism 2 to vibrate within the frame 1 to expel the stones from the kidney.

[0021] Based on the above structure, when using the auxiliary device for kidney lithotripsy, the donor kidney is placed on the placement mechanism 2 for lithotripsy surgery. After the surgery, the vibration mechanism 3 drives the placement mechanism 2 to vibrate within the frame 1, assisting the donor kidney in expelling the lithotripsy fragments. The entire process can be completed by a single person without the need for multiple assistants, preventing frostbite to the assistants' hands. Furthermore, after lithotripsy, the vibration mechanism 3 can assist in the expulsion of the lithotripsy fragments, shortening the lithotripsy time.

[0022] like Figure 6As shown, in some embodiments of this application, the vibration mechanism 3 includes a cam 31 and a drive assembly 32 for rotating the cam 31, the cam 31 being in contact with the bottom of the placement mechanism 2.

[0023] Specifically, the rotation point of cam 31 is not at the center. When the drive component 32 drives cam 31 to rotate, the outer edges of cam 31 at different distances from the rotation point contact the storage mechanism 2 in sequence. Under this action, the storage mechanism 2 moves up and down along the frame 1 to form vibration.

[0024] like Figure 4 , Figure 7 As shown, in some embodiments of this application, the drive assembly 32 includes a drive motor 321, a drive wheel 322 and a driven wheel 323. The output shaft of the drive motor 321 is connected to the drive wheel 322. The driven wheel 323 meshes with the drive wheel 322. A fixed shaft is provided at the center of the driven wheel 323, and the cam 31 is disposed on the fixed shaft.

[0025] Specifically, at least one driven wheel 323 and cam 31 are provided. Providing multiple cams 31 can improve the reliability of vibration of the storage mechanism 2.

[0026] During kidney lithotripsy, the donor kidney needs to be placed in ice-salt water at 0-4°C to maintain its activity. To avoid prolonged immersion of the drive assembly 32 in ice-salt water affecting its service life, this embodiment provides a recessed area at the bottom of the frame 1. The drive assembly 32 is placed in this recessed area. The output shaft of the drive motor 321 in the drive assembly 32 is connected to the center of the drive wheel 322. The rotation of the drive wheel 322 drives at least one driven wheel 323 to rotate in sequence. The fixed shaft on the driven wheel 323 extends into the frame 1 and connects to the cam 31, thereby driving the cam 31 to rotate.

[0027] In some embodiments of this application, the storage mechanism 2 includes a storage platform 21 and a storage component 22. The storage platform 21 is slidably disposed in the frame 1 and vibrates up and down in the frame 1 under the drive of the vibration mechanism 3. One end of the storage component 22 is close to the outer edge of the storage platform 21, and the other end is connected to the side wall of the frame 1.

[0028] In this embodiment, the donor kidney is placed on the placement platform 21 and the ureter is placed on the placement component 22. During the lithotripsy procedure, the flexible ureteroscope sheath is inserted through the ureter into the donor kidney to perform the corresponding operation. After the lithotripsy is completed, the drive component 32 drives the cam 31 to rotate, which in turn causes the placement platform 21 to vibrate within the frame 1, allowing the lithotripsy to be quickly discharged from the donor kidney.

[0029] In some embodiments of this application, the placement component 22 is an inclined tubular structure or an arc-shaped groove structure, and the lower end of the placement component 22 is connected to the side wall of the frame 1. Inclining the placement component 22 is beneficial for the discharge of lithotripsy to the kidney.

[0030] Specifically, clearance holes can be provided at the bottom of the storage unit 22 so that the falling gravel can fall into the frame 1 through the clearance holes, thus preventing it from accumulating on the storage unit 22.

[0031] In some embodiments of this application, the frame 1 is provided with a through hole, and a barrier is provided in the through hole. The barrier allows the flexible ureteroscope sheath to pass through and can also restore the closed state after the flexible ureteroscope sheath is withdrawn, so as to prevent the ice saline in the frame 1 from flowing out.

[0032] In some embodiments of this application, the barrier is composed of a plurality of fan-shaped structures whose outer edges are movably connected to the outer edge of the through hole.

[0033] The fan-shaped structure is made of silicone material. When in use, each fan-shaped structure can avoid the inner side of the frame 1 under the action of external force, allowing the ureteroscope sheath to pass through. After the ureteroscope sheath is removed, the fan-shaped structure can automatically reset and the ice saline in the frame 1 can flow out.

[0034] In some embodiments of this application, a limiting component 4 is provided on the frame 1 next to the through hole for limiting the device used in lithotripsy.

[0035] When using devices such as flexible ureteroscope sheaths for lithotripsy, there is a certain degree of movement involved, so they cannot be directly fixed to the frame 1 or other structures. However, if they are not fixed, the doctor needs to hold the device continuously to prevent it from slipping out of the ureter. In order to free the doctor's hands, this embodiment sets a limiting component 4 on the outside of the frame 1. The limiting component 4 is used to limit the device used in lithotripsy surgery, so that it will not slip out of the ureter when the doctor is not holding it, and it also allows for a certain degree of mobility during the lithotripsy surgery.

[0036] In some embodiments of this application, the limiting component 4 includes an elastic connector 41, one end of which is connected to the frame 1, and the other end of which is detachably connected to the device used in lithotripsy. During use, the expansion and contraction of the elastic connector 41 ensures that the device's movement is not restricted.

[0037] like Figure 5As shown, specifically, the elastic connector 41 includes a limiting groove 411 disposed on the frame 1. A vertically extending guide post 412 is disposed within the limiting groove 411. An elastic element 414 and a slider 413 are sleeved on the guide post 412, and the slider 413 is connected to one end of the connector. In use, the other end of the connector is connected to the device used in lithotripsy. During the procedure, pulling the device causes the connector to move the slider 413 along the guide post 412. The elastic element 414 contracts to avoid this movement. After the device's movement is complete, the elastic element 414 resets, stabilizing the device in a specific position.

[0038] More specifically, the connector can be set as a strap, or a clip, hook or other component can be set at the other end to facilitate connection with surgical instruments; the elastic element 414 is a spring.

[0039] In some embodiments of this application, the placement platform 21 is provided with a fastener 211 for fixing the donor kidney to the placement platform 21.

[0040] In this embodiment, the fastener 211 is a structure such as a strap or buckle. When in use, the fastener 211 is used to fix the donor kidney on the placement platform 21 to prevent the donor kidney from rolling during surgery or vibration.

[0041] More preferably, the fastener 211 is an elastic mesh structure, with one end fixed to the side of the placement platform 21 and the other end detachably fixed to the other side of the placement platform 21 by means of straps, buckles, etc. This way, the contact area with the donor kidney is larger when fixed, and the donor kidney will not be damaged.

[0042] The specific method of using the auxiliary device for kidney lithotripsy provided in this embodiment is as follows: Inject ice-cold saline into the frame 1, place the donor kidney on the placement platform 21 and the ureter on the placement component 22, fix the donor kidney with the fixing component 211, manually insert the ureteroscope sheath through the barrier into the frame 1, and insert it into the donor kidney along the ureter under the guidance of the placement component 22 to perform lithotripsy, while connecting the elastic connector in the limiting component 4 to the ureteroscope sheath.

[0043] After the surgery, the flexible ureteroscope sheath is removed, and the drive motor 321 is started. The drive motor 321 drives the active wheel 322 to rotate, which in turn drives the driven wheel 323 and the cam 31 to rotate. Finally, the placement platform 21 vibrates up and down inside the frame 1 to assist the donor kidney in expelling the stones inside.

[0044] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
