Description

Technical Field

[0001] This application relates to the technical field of urine drainage, and particularly relates to a segmented percutaneous upper urinary tract implantation drainage kit. Background Art

[0002] At present, there are mainly two ways for urine drainage of the upper urinary tract: the first is the internal drainage method of implanting a stent into the ureter through the urethra. The implanted ureteral stent has different placement times according to different materials, but all need to be replaced regularly, and various complications are difficult to avoid during long-term placement, such as scale blockage of the drainage tube, severe bladder irritation, urinary tract infection, hematuria, tube detachment, etc. The occurrence of the above situations requires treatment in the hospital, resulting in high medical costs and physical and mental exhaustion of patients. And it is difficult to avoid chronic inflammatory stimulation during the long-term implantation of the ureteral stent, which may induce malignant lesions. The second is percutaneous nephrostomy drainage, which belongs to the external drainage method. The external drainage is mainly for the pipeline to be indwelled and fixed outside the body (waist), requiring daily pipeline maintenance, with strong discomfort and an unbeautiful appearance. Various problems will occur after long-term placement, such as repeated inflammatory stimulation of the fistula opening, especially when the pipeline falls off, resulting in the occlusion of the fistula tract and the need for re-operation to puncture and place the drainage tube, which has a great impact on the quality of daily life and the psychology of patients. Such patients are often unwilling or do not want to go out to participate in social activities, and have typical psychological problems such as inferiority and anxiety. Other complications are as described above for the internal drainage tube, and the frequency of regular replacement is higher, generally at least once a month.

[0032] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0033] In the description of the present application, it should be noted that, unless otherwise clearly defined and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, an electrical connection, or a communication with each other; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific situations.

[0034] Specifically, the embodiment of the present application provides a segmented percutaneous upper urinary tract implantation drainage kit for draining urine in the kidney into the bladder, and it is a percutaneous implantation design, which has the advantages of minimally invasive, simple, fast, stronger stability, and fewer complications. This technical means is different from the two commonly used clinical drainage methods (internal drainage of an indwelling stent through the ureter and external drainage of percutaneous nephrostomy), effectively reducing various complications and the pain of repeated treatment brought by the two commonly used clinical drainage methods, and at the same time solving the problems of the incomplete human appearance and the aesthetic impact on the patient's psychology caused by external drainage.

[0035] Please refer to Figures 1 to 6, the segmented upper urinary tract percutaneous implantation drainage kit includes: a kidney-end drainage device 1, a bladder-end drainage device 2, an intermediate drainage tube 3, and a locking structure 4.

[0036] The kidney-end drainage device 1 is provided with a kidney insertion end 11 and a first connecting drainage tube 12; the kidney insertion end 11 has a spherical or lantern-shaped hollow space in its natural state, and the kidney insertion end 11 is connected to the first connecting drainage tube 12; the bladder-end drainage device 2 is provided with a bladder insertion end 21 and a second connecting drainage tube 22; the bladder insertion end 21 has a spherical or lantern-shaped hollow space in its natural state, and the bladder insertion end 21 is connected to the second connecting drainage tube 22; the intermediate drainage tube 3 is provided with a first connecting end and a second connecting end; the first connecting end can be connected to the first connecting drainage tube 12, and the second connecting end can be connected to the second connecting drainage tube 22; the locking structure 4 is arranged at the first connecting end and the second connecting end; the locking structure 4 includes a plurality of hollow buckle belts 41 and a plurality of pointed triangular cone hooks 42, and the hollow buckle belts 41 and the pointed triangular cone hooks 42 are arranged in one-to-one correspondence; when the first connecting drainage tube 12 extends into the first connecting end, the locking structure 4 is squeezed to lock the hollow buckle belt 41 and the pointed triangular cone hook 42 so that the first connecting end fixes the first connecting drainage tube 12; when the second connecting drainage tube 22 extends into the second connecting end, the locking structure 4 is squeezed to lock the hollow buckle belt 41 and the pointed triangular cone hook 42 so that the second connecting end fixes the second connecting drainage tube 22.

[0037] When installing the segmented upper urinary tract percutaneous implantation drainage kit, an internal rigid push tube 5 can also be used in cooperation. The diameter of the internal rigid push tube 5 is smaller than the diameter of the first connecting drainage tube 12. The internal rigid push tube 5 passes through the first connecting drainage tube 12 and extends into the kidney-end drainage device 1 to support the kidney insertion end 11 to form a linear shape. The diameter of the internal rigid push tube 5 is smaller than the diameter of the second connecting drainage tube 22. The internal rigid push tube 5 passes through the second connecting drainage tube 22 and extends into the bladder-end drainage device 2 to support the bladder-end drainage device 2 to form a linear shape. The internal rigid push tube 5 is placed in the intermediate drainage tube 3 to assist the intermediate drainage tube 3 to smoothly establish a tunnel through subcutaneous puncture. Its percutaneous implantation is assisted by the internal rigid push tube 5. Otherwise, it is not easy to establish a tunnel through subcutaneous puncture.

[0038] As Figure 6 shown, the internal rigid push tube 5 is set according to the size and shape of the kidney-end drainage device 1 and the bladder-end drainage device 2, and is made of a rigid material. A through channel 51 is provided in the middle of the internal rigid push tube 5 to facilitate the entry of the puncture guide wire. The end of the push tube is arc-shaped to prevent tissue damage when the steel wire is stretched forcefully.

[0039] When setting the segmented upper urinary tract percutaneous implantation drainage kit, first insert a guide wire through percutaneous nephrostomy, then insert a fascial dilator under the guidance of the guide wire. After successful dilation, remove the fascial dilator and further dilate with a sheath dilator. Remove the inner sheath and the guide wire of the sheath dilator and retain the outer sheath of the sheath dilator. Insert the kidney-end drainage device 1 through the outer sheath of the sheath dilator. Similarly, insert a guide wire through puncture at the bladder, then insert a fascial dilator under the guidance of the guide wire. After successful dilation, remove the fascial dilator and further dilate with a sheath dilator. Remove the inner sheath and the guide wire of the sheath dilator and retain the outer sheath of the sheath dilator. Insert the bladder-end drainage device 2 through the outer sheath of the sheath dilator.

[0040] Before the kidney-end drainage device 1 is implanted into the subcutaneous tissue and extends into the kidney, insert an internal rigid push tube 5 into the kidney-end drainage device 1 to support and flatten the kidney-end drainage device 1, and support the kidney-end drainage device 1 to form a linear shape with the kidney insertion end 11. Insert a guide wire into the internal rigid push tube 5 to guide the internal rigid push tube 5, so as to realize the linear internal rigid push tube 5 being inserted into the kidney-end drainage device 1 through the sheath of the fascial dilator. Then, withdraw the internal rigid push tube 5, and the kidney insertion end 11 resumes to a spherical shape and is clamped in the kidney.

[0041] Before the bladder-end drainage device 2 is implanted into the subcutaneous tissue and extends into the bladder, insert an internal rigid push tube 5 into the bladder-end drainage device 2 to support and flatten the bladder-end drainage device 2, and support the bladder-end drainage device 2 to form a linear shape. Insert a guide wire into the internal rigid push tube 5 to guide the internal rigid push tube 5, so as to realize the linear internal rigid push tube 5 being inserted into the bladder-end drainage device 2 through the sheath of the fascial dilator. Then, withdraw the internal rigid push tube 5, and the bladder insertion end 21 resumes to a spherical shape and is clamped in the bladder.

[0042] After implanting the kidney-end drainage device 1 and the bladder-end drainage device 2, implant the intermediate drainage tube 3 subcutaneously, and then adjust the lengths of the kidney-end drainage device 1, the bladder-end drainage device 2 and the intermediate drainage tube 3 as needed (cut off the excess length), and connect the kidney-end drainage device 1 and the bladder-end drainage device 2 to the intermediate drainage tube 3 respectively and then close the pipeline, which can avoid the need for large-area surgical placement of drainage pipelines, and there is no need to leave and fix the pipelines outside the body, improving the user experience.

[0043] Such as Figure 4 、 Figure 5As shown, the hollow buckle belt 41 is rectangular, and multiple hollow buckle belts 41 are arranged on a first straight line; the pointed triangular pyramid hook 42 is wedge-shaped, and multiple pointed triangular pyramid hooks 42 are arranged on a second straight line, and the first straight line and the second straight line are arranged in parallel at intervals; the first straight line, the second straight line and the central axis of the intermediate drainage tube 3 are arranged in parallel. When the locking structure 4 is squeezed to lock the hollow buckle belt 41 and the pointed triangular pyramid hook 42, the diameter of the intermediate drainage tube 3 is equal to the diameter of the first connecting drainage tube 12 or the second connecting drainage tube 22.

[0044] As Figure 3 shown, the intermediate drainage tube 3 further includes an anti-reflux structure 31; the anti-reflux structure 31 includes multiple elastic membrane flaps 311 arranged at intervals, and the multiple elastic membrane flaps 311 are arranged in an up-and-down spiral shape in the intermediate drainage tube 3, and the elastic membrane flaps 311 are inclined towards the bladder end drainage device 2.

[0045] Furthermore, the area of each elastic membrane flap 311 is less than or equal to one-third of the cross-sectional area of the intermediate drainage tube 3, and at least three elastic membrane flaps 311 are provided.

[0046] As Figure 1 shown, the kidney insertion end 11 includes: a first elastic support structure 111 and a rotating diversion device 112.

[0047] The first elastic support structure 111 includes a first port ring 1111, a first support ring 1112 and multiple first elastic steel wires 1113 bent into an arc shape. The first port ring 1111 is arranged at the pipe orifice of the first connecting drainage tube 12. The diameter of the first support ring 1112 is smaller than the diameter of the first port ring 1111. The two ends of the first elastic steel wire 1113 are respectively arranged on the first port ring 1111 and the first support ring 1112. The first elastic steel wire 1113 is in a bent state in the natural state, and all the first elastic steel wires 1113 form a hollow space in the shape of a sphere or a lantern; the rotating diversion device 112 is arranged inside the first elastic support structure 111; the rotating diversion device 112 includes a driving ring seat 1121, a rotating ring 1122, rotating blades 1123 and a driving power source 1124. The driving ring seat 1121 is arranged at the pipe orifice of the first connecting drainage tube 12. The rotating ring 1122 is rotatably arranged on the driving ring seat 1121. The rotating blades 1123 are arranged inside the rotating ring 1122. The driving power source 1124 is connected to the driving ring seat 1121.

[0048] As Figure 1As shown, there are at least two rotating blades 1123, and the two rotating blades 1123 are in a spiral structure. The rotating blades 1123 are bent toward the side away from the first connecting drainage tube 12, and the ends of the rotating blades 1123 are bent toward the central axis of the first connecting drainage tube 12, and the area of ​​the rotating blades 1123 is less than or equal to half the area of ​​the tube opening of the kidney-end drainage device 1.

[0049] The first elastic support structure 111 uses a curved elastic steel wire to provide a supporting and protective space. The connection points (circular) at both ends of the steel wire are designed to be small at the top and large at the bottom, which is conducive to inserting a hard top tube into the device to facilitate the insertion and removal of the device (stretching the curved steel wire through the built-in hard top tube 5) without damaging other tissues. The steel wire is in a curved state in a natural state. After bending, its area exceeds the urine inlet at the end, so it plays a role in fixing the device and preventing it from falling off, and at the same time, it can prevent stones formed in the kidney from entering the drainage pipe and causing blockage.

[0050] Two spirally shaped, slightly concave rotating blades 1123 are placed at the urine drainage port (the area occupied does not exceed one-half of the drainage port). Their function is to form a local vortex of urine through high-speed rotation, thereby playing an inward suction effect to enhance the discharge of urine flow. At the same time, the rotation can effectively reduce the fouling and blockage of the inlet and the appearance of urine crystals in the kidney that affect the drainage effect.

[0051] See also Figure 1 A driving ring seat 1121 of a rotating blade 1123 is provided at the urine inlet to provide rotation of the rotating blade 1123, and an electric wire is connected through the driving ring seat 1121 to provide energy. The rotating ring 1122 adopts an ultra-smooth design to reduce resistance and energy used, thereby extending the use time.

[0052] The wires of the kidney insertion end 11 are completely placed in the tube wall for sealing and protection, and are led out from the side wall at the far end to connect to a micro battery as a driving power source 1124. The micro battery can be placed in a space created in the direction of the front wall of the abdomen. The rotating ring 1122 is controlled by setting the battery, for example, discharging and rotating once every ten minutes or setting other intervals.

[0053] When the battery energy disappears or a fault occurs, there is no need to replace it immediately and it can still be used. It only needs to be replaced when the inlet of the pipeline is completely blocked; that is to say, after the battery energy is consumed, the implanted drainage kit can still continue to drain for a long time, and the maximum replacement time is extended under double protection. The same is true for the bladder end design. When the bladder outlet is scaled and blocked, the end abnormality can be cleaned through the urethra under an endoscope. If the anti-reflux leaf (elastic membrane flap 311) at the end is damaged during the operation, the second anti-reflux leaf established in the intermediate connecting pipe will play a role. All the above designs consider extending the service life as much as possible.

[0054] As Figure 2 shown, the bladder insertion end 21 includes: a second elastic support structure 211 and a one-way valve device 212.

[0055] The second elastic support structure 211 includes a second port ring 2111, a second support ring 2112, and a plurality of second elastic steel wires 2113 bent in an arc shape. The second port ring 2111 is arranged at the pipe orifice of the second connecting drainage pipe 22. The diameter of the second support ring 2112 is smaller than the diameter of the second port ring 2111. Both ends of the second elastic steel wire 2113 are respectively arranged at the second port ring 2111 and the second support ring 2112. The second elastic steel wire 2113 is in a bent state in the natural state, and all the second elastic steel wires 2113 form a hollow space in a spherical or lantern shape; the one-way valve device 212 is arranged inside the second elastic support structure 211; the one-way valve device 212 includes a rotating shaft 2121, a rotating flap 2122, and a blocking plate 2123. The rotating shaft 2121 is the chord of the pipe orifice of the second connecting drainage pipe 22. The blocking plate 2123 is in a minor segment shape, and the rotating flap 2122 is in a major segment shape. The blocking plate 2123 and the rotating flap 2122 are arranged on both sides of the rotating shaft 2121. The plane where the rotating flap 2122 is located and the plane where the blocking plate 2123 is located are arranged at a first included angle. The blocking plate 2123 horizontally blocks the pipe orifice of the second connecting drainage pipe 22. When the urine floats the rotating flap 2122, the rotating flap 2122 rotates a first included angle along the rotating shaft 2121 and then blocks the pipe orifice of the second connecting drainage pipe 22.

[0056] Furthermore, the area of the blocking plate 2123 is equal to one-fifth of the area of the pipe orifice of the bladder end drainage device 2, and the area of the rotating flap 2122 is equal to four-fifths of the area of the pipe orifice of the bladder end drainage device 2.

[0057] The one-way valve device 212 designed at the urine outlet is an automatic anti-urine reflux device. A shaft is established at one-fifth of the circular outlet, and four-fifths of the area is a rotating flap 2122 connected to the rotating shaft 2121 (the rotating flap 2122 can move up and down), which is conducive to the closing of the rotating flap 2122 to prevent urine reflux. In the natural state, the rotating flap 2122 is in a semi-open state to facilitate the natural discharge of urine. However, when the urine in the bladder increases to a certain level, due to the relatively heavy mass of the metal thick plate, it will assist the automatic closing of the rotating flap 2122 at this time.

[0058] Furthermore, the outer surfaces of the kidney end drainage device 1 and the bladder end drainage device 2 are also covered with a protective layer that is antibacterial, acid and alkali resistant, and corrosion resistant.

[0059] As Figure 3 shown, the end of the intermediate drainage tube 3 is bullet-shaped, and the end of the intermediate drainage tube 3 is provided with micro-holes 32.

[0060] During use, under the positioning guidance of B-ultrasound, a guide wire is percutaneously punctured into the kidney, and then a fascia dilator is inserted under the guidance of the guide wire. After successful dilation, the fascia dilator is removed and further dilated with a sheath dilator. The inner sheath and the guide wire of the sheath dilator are removed, and the outer sheath of the sheath dilator is retained. The kidney end drainage device 1 is inserted through the outer sheath of the sheath dilator. Similarly, the bladder end drainage device 2 is inserted by the same percutaneous puncture method at the bladder. The skin is incised to the subcutaneous loose tissue layer at the percutaneous puncture sites at both ends, and the incision size is about 2 cm. Then, a subcutaneous puncture is performed through the lumbar incision, and the direction is an oblique puncture forward and inward to establish a subcutaneous tunnel. The intermediate drainage tube 3 is inserted through this tunnel. After successful placement, the redundant tubes at both ends are cut off, and the kidney end drainage device 1 and the intermediate drainage tube 3, and the intermediate drainage tube 3 and the bladder end drainage device 2 are respectively connected through a squeezing lock structure 4, thus forming a complete closed drainage line. The skin incisions at both ends are sutured. The surgical operation causes little tissue damage, has almost no impact on the skin appearance, and has a fast postoperative recovery, belonging to a new minimally invasive surgical method. In the future, when it is necessary to remove or replace the segmented percutaneous upper urinary tract implantation drainage kit, the original skin incisions at both ends can be incised. After finding the segmented percutaneous upper urinary tract implantation drainage kit, a guide wire is inserted, and the required operation can be completed under the guidance of the guide wire without repositioning and puncturing, and it can be completed under local anesthesia, with convenient operation.

[0061] The first elastic steel wire 1113 of the first elastic support structure 111 and the second elastic steel wire 2113 of the second elastic support structure 211 are of hard elasticity and can be made of various synthetic metals or nickel-titanium memory metals, etc. They have a smooth surface, are not prone to scaling, and have strong corrosion resistance. The main requirement is that they have a supporting effect to provide a protective space. The number of steel wires designed is 6 - 8. In the natural state, the steel wire is in a bent state. After bending, since its area exceeds the drainage openings at both ends, it also plays a role in fixing the device and preventing detachment, providing a stable protective space, and at the same time, it can prevent the stones formed in the kidney from entering the drainage pipeline and causing blockage.

[0062] After being closed, the segmented percutaneous upper urinary tract implantation drainage kit will form an absolutely stable structure by fitting with tissues. The first elastic support structure 111 and the second elastic support structure 211 are firmly fixed to the bladder and kidney ends and are not prone to movement, which will greatly reduce discomfort and bladder irritation symptoms, thereby further ensuring the patient's quality of life and stable treatment effect.

[0063] The kidney-end drainage device 1 and the bladder-end drainage device 2 can be trimmed according to the needs of the human body. The pipeline, rotary blade 1123, elastic membrane flap 311, etc. can be made of silicone materials or other polymeric materials that are both hard and soft. The inner diameters of the kidney-end drainage device 1 and the bladder-end drainage device 2 are relatively large, and it is not easy to become blocked during long-term drainage. Even when the service time is extended, the urine drainage effect is ensured. The size of the pipeline can be designed according to the required situation, and it is recommended to be between F10 - 14. If it is too large, it may increase the discomfort after implantation.

[0064] The segmented percutaneous upper urinary tract implantation drainage kit provided by the embodiment of the present application can be implanted into the kidney and bladder respectively by setting the kidney-end drainage device and the bladder-end drainage device. The middle drainage tube can be minimally invasively implanted into the subcutaneous tissue. After the lengths of the first connecting drainage tube of the kidney-end drainage device and the second connecting drainage tube of the bladder-end drainage device are cut according to the needs, they can be locked with the middle drainage tube through a locking structure, which can avoid the need for large-area surgical placement of drainage pipelines and does not require the pipelines to be indwelled and fixed outside the body, improving the user experience. After the drainage pipeline is closed, it will form an absolutely stable structure by fitting with tissues. The bladder and kidney ends are firmly fixed and not prone to movement, which will greatly reduce discomfort and bladder irritation symptoms, thereby further ensuring the patient's quality of life and stable treatment effect.

[0065] The segmented percutaneous upper urinary tract implantation drainage kit provided by the embodiment of the present application is of an implantable design, so it does not affect the appearance, protects the patient's privacy, and at the same time ensures the quality of life, and has significant clinical significance compared with the two drainage methods described above.
