Description

Technical Field

[0001] This utility model relates to ureteroscopic lithotripsy, specifically to a multi-channel urinary system stone removal device. Background Technology

[0002] The traditional method for treating urinary tract stones is ureteroscopic lithotripsy. Doctors typically insert a ureteroscope into the urethra, through the bladder and ureter, to reach the stone. If the stone is small, a basket is usually used, which is inserted through the endoscope's energy channel to trap and remove the stone. When the stone is too large, the doctor first uses the energy device to break it down into smaller fragments before using the basket. This process is very time-consuming when there are many stones. Furthermore, the endoscope and basket must be inserted and removed together, causing significant damage to the ureter and surrounding tissues. Additionally, some tiny stones cannot be removed using the basket, and these remaining small stones can eventually grow into larger stones. Therefore, there is an urgent clinical need for new equipment and methods to treat urinary tract stones.

[0003] Traditional flexible ureteroscopes require multiple insertions and removals from the body, causing significant tissue damage, taking a long time, and failing to remove small stone fragments, which can later grow into large stones. Utility Model Content

[0031] The present invention or its technical solution will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0032] In the description of this utility model, it should be understood that the terms "front," "rear," "left," "right," "upper," and "lower," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. The term "multiple" refers to two or more.

[0033] In the description of this utility model, it should be noted that, unless otherwise specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to mechanical or electrical connections, or internal connections between two components. They can be direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0034] Example 1

[0035] Please see Figure 1 This utility model provides a multi-channel urinary system stone removal device, which includes an insertion part 2 and an operating part 1. The insertion part 2 is adapted to enter the patient's body, while the operating part is adapted for use by a user, such as a doctor, to hold and operate. Please refer to [link to relevant documentation]. Figure 2 and Figure 3 The insertion part 2 is continuously provided with a front end 21, a bending part 22, and a tube body 23 from distal to proximal. The front end 21 of the insertion part 2 is provided with an imaging element 211 for capturing the cavity, an infusion outlet 212, and a suction inlet 213. The insertion part 2 is provided with at least one first tube 25, at least one second tube 26, and a steel wire 27. The first tube 25 is used to deliver liquid or energy devices into the human body, and the second tube 26 is used to expel liquid from the body. The operating part 1 is located at the base end of the insertion part 2. The operating part 1 includes a gripping part 11, a bending operating part 12, a first connector 120, and a second connector 121. The gripping part 11 is for the user to hold and use. The bending operating part 12 is controlled by the steel wire 27 to allow the bending part 22 to bend at least in the vertical direction. The first connector 120 is connected to the first tube 25, and the second connector 121 is connected to the second tube 26 (see [reference]). Figure 4The first connector 120 is adapted to connect to an external irrigation device, and the second connector 121 is adapted to connect to a negative pressure suction device. It is understood that the first conduit 25 can be used for energy devices, such as laser fibers, to break up stones before the irrigation medium enters. When it is necessary to deliver the irrigation medium into the cavity, physiological saline is delivered so that the second conduit 26 constitutes an irrigation conduit. Thus, the multi-channel urinary system stone removal device provided by this invention can simultaneously achieve stone fragmentation, irrigation, suction, and visual operation on a single device. When the operator uses the removal device provided by this invention for stone fragmentation and removal, the stone fragmentation operation is performed by inserting a traditional energy device, and the stone removal operation is performed by irrigation and suction. This process does not require the use of a basket device, and the instruments do not need to repeatedly enter and exit the body, allowing the stones to be pulverized into small pieces and extracted from the patient's body, making the operation highly efficient and convenient.

[0036] It is understandable that the outer diameter of the insertion part 2, as a channel suitable for insertion into the cavity, is strictly limited. Therefore, the number and size design of the first and second conduits formed within it are crucial to the success of stone removal. In some embodiments of this invention, the number of first conduits 25 can be multiple; please refer to [reference needed]. Figure 2 The insertion section 2 has two first conduits 25 and one second conduit 26 inside. The first conduits 25 are used for irrigation media such as physiological saline, so their small inner diameter allows for the smooth passage of physiological saline. Furthermore, multiple irrigation conduits facilitate the impact of stones from different directions, enabling their smooth expulsion. The second conduit 26 serves as a suction conduit, primarily used for aspirating waste fluid containing stones. Therefore, its inner diameter needs to be designed to allow for the smooth expulsion of stones. Based on this requirement, the second conduit 22 has a larger inner diameter and is configured as a single unit. In this embodiment, the insertion section 2 is shaped like a slender cylinder with an outer dimension of less than 4mm, a size that allows for easy insertion into the urethra, bladder, and ureter. The operator can manipulate the bending mechanism 12 to control the shape of the bending section via a steel wire, thereby aligning the tip of the insertion section 2 with the surgical position. A camera mounting base, a camera, and a lighting system are installed at the front end 21, which has two injection outlets 212 at the end of the injection lines and a suction inlet 213 at the beginning of the suction lines.

[0037] In some embodiments of this utility model, the removal device further includes an irrigation flow control mechanism. This allows the device to control the irrigation flow rate during the removal of urinary stones, preventing excessive or insufficient pressure within the cavity. It is understood that the irrigation flow control mechanism can function independently of the flow control mechanism of the irrigation device, or they can work together to adjust the irrigation flow rate. See also... Figure 1 , Figures 5-8The infusion flow control mechanism includes a second operating element 13 and a position detection element 14. The second operating element 13 is movably mounted on the operating unit 1. The position detection element 14 is used to detect changes in the position of the second operating element 13 and is communicatively connected to the infusion device to adjust the infusion flow rate. When a large infusion flow rate is required, the user can control the action of the second operating element to send a large flow rate request to the infusion device. After receiving the request, the infusion device adjusts the flow rate level. In some specific embodiments, the infusion flow control mechanism includes a manual operating unit 131, a rotating unit 132, an angle sensor 14, and an elastic reset element 133. The rotating unit 132 is rotatably connected to the operating unit 1. The manual operating unit 131 is connected to the rotating unit 132 to drive the rotating unit to rotate relative to the operating unit 1. The angle sensor 14 is mounted on the operating unit 1 and is used to detect the rotation angle of the rotating unit 132. The angle sensor 14 is communicatively connected to the infusion device to adjust the flow rate. The elastic reset member 133 provides reset power to the manual operation unit 131 so that the manual operation unit 131 can quickly return to its original position. Exemplarily, the rotating part 132 includes a rotating body 1321 and a gear 1322. The gear 1322 is rotatably mounted on the operation unit 1. The rotating body 1321 has a rack segment 1320 that meshes with the gear 1322. The angle sensor 14 is used to detect the rotation angle of the gear 1322.

[0038] In this embodiment, please refer to 1 and Figure 9 The operating part 1 includes a housing 100. Specifically, the housing 100 includes a left housing 101 and a right housing 102. The housing 100 defines an installation space, and the upper part of the housing 100 forms an operating area, the middle part forms a gripping area, and the lower part is connected to the insertion part 2. The gripping area forms the gripping part 11. The operating area is provided with a bending operating part 12 and an infusion flow control mechanism. Please refer again. Figures 5-8The manual operation unit 12 penetrates the housing 100. A first fixed plate 15 and a second fixed plate 16 are fixedly installed opposite each other within the housing 100. The first fixed plate 15 and the second fixed plate 16 are connected. The rotating part 132 is rotatably connected between the first fixed plate 15 and the second fixed plate 16. The gear 1322 is rotatably connected to the first fixed plate 15 via a rotating shaft 17. A mounting rod 18 is provided on the rotating shaft facing the second fixed plate 16. An angle sensor 14 is provided on the second fixed plate 16. The mounting rod 18 pivotally passes through the angle sensor. The rotating body drives the gear 1322 to rotate, thereby driving the mounting rod 18 to rotate synchronously. Furthermore, the angle sensor 14 is mounted on the second fixed plate 16 via a mounting platform 141. Additionally, a tension spring 133 is provided between the first fixed plate 15 and the rotating body 1321. The rotating body 1321 and the first fixed plate 15 achieve rotational displacement through an arc-shaped groove 41 and a sliding block 42.

[0039] Optionally, the operating part includes a third connector 122 for the passage of the energy device. The third connector 122 is connected to at least one of the first conduits 25. In this way, the energy device can reach the target cavity through the first conduit 25. Thus, the first conduit 25 and the second conduit 26 form an irrigation channel, a suction channel and an energy device channel, avoiding the current multi-channel congestion that causes the outer diameter of the insertion part to be too large to be suitable for the urethra.

[0040] For example, the left housing 101 and the right housing 102 are snapped together. The overall shape of the housing 100 resembles a handle. The manual operation part 131 includes a flow trigger mounted on the upper part of the housing 100, which is suitable for operation by the index finger. The bending operation part 22 includes a bending trigger mounted on the upper part of the housing 100, which is suitable for operation by the thumb. The middle part has a near-cylindrical shape to form a grip part that is easy for doctors to hold. In this way, the movement of the bending part and the amount of perfusion flow can be controlled by one hand while holding the clearance device. The lower middle section of the housing has a first connector 120 for the infusion medium, a second connector 121 for negative pressure suction, and a third connector 22 for the energy device. The proximal ends of the first conduit 25 and the second conduit 26 extend into the housing 100 to connect with the first connector 120, the second connector 121, and the third connector 122 on the housing. Each of the three connectors constitutes an infusion inlet, a suction outlet, and an inlet for the energy device, allowing doctors to freely select the appropriate function based on their needs for lithotripsy, infusion, and suction stone removal. Frequent basket replacements are unnecessary, and the operation is fast and efficient.

[0041] In some examples, please refer to Figure 14 and Figure 15The first fixing plate 15 has three first fixing holes 152 on its back side B, which mate with the right shell fixing platform 151 and the three positioning pins 153 on the right shell, respectively. The three positioning pins 153 on the right shell, after mating, penetrate the first fixing plate 15. The first fixing plate 15 has a tension spring fixing hook 154, a first flow trigger fixing hole 155, a top plate fixing pin 156, and a first gear fixing hole 157 on its front side A. (See also...) Figure 8 The flow trigger 13 has a first positioning shaft 135, a tension spring fixing hook 136, an arc-shaped slide groove 41, and a transmission rack 1320 on its front side A. The flow trigger 13 has a second positioning shaft (not shown in the figure) on its back side; the second positioning shaft on the flow trigger 13 mates with the flow trigger 13 fixing hole 155 on the first fixing plate, and the top plate fixing pin 156 slidably passes through the arc-shaped slide groove 41 of the flow trigger. Tension springs 133 are fixed to the flow trigger and the tension spring fixing hooks 136 and 154 on the first fixing plate. The gear 1322 has a second rotating shaft and sensor mounting rod mounted on its front side, and a first rotating shaft mounted on its back side, with teeth on its outer circumference. After installation, the teeth of the pinion will mesh with the rack section of the flow trigger. Please refer to... Figure 17 and Figure 18 The second fixing plate 16 has two through-hole second fixing holes 161, one through-hole second flow trigger fixing hole 164, one through-hole second gear fixing hole 165, two sensor height limiting platforms 162, and two sensor mounting fixing platforms 163 on its front side. The three second fixing holes respectively mate with the positioning pins 153 on the right housing passing through the first fixing plate 15. The second flow trigger fixing hole 164 mates with the first positioning shaft 135 on the flow trigger, and the second gear fixing hole 165 mates with the second rotating shaft of the gear. After mating, the sensor mounting rod extends from the second fixing plate, and the sensor mounting shaft on the pinion is connected to the angle sensor. The angle sensor is fixed to the front side of the second fixing plate via the two sensor height limiting platforms 162 and the two sensor mounting fixing platforms 163. When the trigger on the flow trigger is pressed counterclockwise, the angle sensor mounting rod on the gear will rotate clockwise. When the trigger is released, due to the tension of the spring, the trigger will spring back, and the angle sensor mounting shaft on the gear will rotate counterclockwise. The angle sensor will detect the rotation angle of the flow trigger. It sends a corresponding electrical signal. The larger the angle of the flow trigger, the higher the electrical signal value. After receiving the electrical signal, the injection pump adjusts the injection flow rate according to the high or low value of the electrical signal.

[0042] To enable the first connector 120, the second connector 121, and the third connector 122 to mate with the first and second pipelines, and to achieve a combination of energy equipment, filling, and suction functions, please refer to [link to relevant documentation]. Figure 4 , Figure 10 and Figure 11 The operating unit is internally equipped with a transition pipe 3, which includes a first channel 31 and multiple second channels. Figure 10The diagram illustrates two second channels 32 and 33. A first channel 31 is connected to multiple second channels 32 and 33. The first channel 31 is connected to a first connector 120 for the injection medium to enter. Each second channel 32 and 33 has an inlet end and two outlet ends 321 and 322. The inlet end is connected to a third connector 122 for the energy device to enter one of the second channels. It is understood that the third connector and the inlet end can be designed as an integral part or as separate parts. The two outlet ends 321 and 322 are respectively connected to two first pipelines 25. Correspondingly, two injection outlets 121 are formed at the front end of the insertion part 2. To facilitate the insertion of the energy device, especially for rigid energy devices, the third connector 122 is coaxially arranged with one of the second channels 32, allowing the energy device to smoothly enter the second pipeline through the second channel.

[0043] In this embodiment, please refer to Figure 11 Two second channels 32 and 33 are provided, and they are connected by a middle channel 323. Thus, when the first pipe 25 is not flowing with liquid, the laser fiber of the energy device is fed into one of the first pipes 25 through the third connector 122 and one of the second channels 32 and 33, thereby completing the feeding of the energy device. When the energy device inlet, i.e., the third connector 122, is closed, the first connector 120 is adapted to connect to the infusion device. The infusion device feeds the infusion liquid, such as physiological saline, through the first channel 31 and into one of the second channels 33. The water flow is divided into two parts: one part flows out from the first channel 32, and the other part flows out from the second channel 33.

[0044] In some embodiments of this utility model, the first connector 120 and the third connector 122 are disposed through the operating part 1. One end of the first connector 120 is connected to the first channel 31 inside the operating part, and the other end is adapted to be connected to the infusion device. Please refer to [link to relevant documentation]. Figure 4 One end 1215 of the second connector 121 is located inside the housing and connected to the second pipeline, while the other end is located outside the housing and has a transition section 1210 and a connecting end 1211. The connecting end 1211 is adapted to connect to the suction device. The transition section 1210 is provided with a regulating valve 1212 to regulate the negative pressure suction pressure. In some examples, please refer to... Figure 12 The transition section 1210 is provided with an opening 1213, and the regulating valve 1212 includes a cover movably disposed at the opening 1213, the cover covering the opening, and the regulating valve including a rotating cover ( Figure 12 ) or sliding cover 1216 ( Figure 13The pressure of the negative pressure suction is adjusted by rotating or sliding the cover to seal or adjust the size of the opening. For example, the rotating cover has a slot 1214 for adjusting the size of the opening, and the cover can move relative to the opening to adjust the size of the opening. The operator can rotate the cover with their fingers to match the slot 1214 on the rotating cover with the opening 1213, thereby achieving the states of the opening being closed, open, or partially open.

[0045] For example, during use, the operator can insert an energy device, such as a laser fiber, into the inlet of the third connector 122 and then extend it from the end face infusion outlet 212 at the front end of the insertion part 2. The laser fiber is used to pulverize the stones in the body, which are then drawn out through the suction channel of the second conduit 26. The stones enter the second conduit 26 from the end face suction inlet 213 at the front end of the insertion part and are drawn up to the second connector 121 on the operating part, where they are finally removed. During this process, the operator can simultaneously control the infusion flow rate and the bending of the curved part using the index finger and thumb of the hand holding the grip.

[0046] The method for adjusting the infusion flow rate is as follows: pressing down the flow trigger will cause the gear to rotate. After the angle sensor detects the rotation angle, it can send an electrical signal, thereby adjusting the infusion flow rate of the connected infusion pump.

[0047] The method for adjusting the negative pressure is as follows: when the negative pressure for aspirating stones is too high, the operator can adjust the position of the rotating or sliding cover to adjust the vacuum level within the connection end. A higher vacuum level results in a stronger suction force, and a lower vacuum level results in a weaker suction force. In this way, when using the removal device provided by this invention for stone fragmentation and removal, the operator does not need to use a basket device and can break the stones into small pieces and remove them from the patient's body without multiple entries and exits.
