Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to steam therapy systems and steam supply devices. Background Technology

[0002] With the continuous development of minimally invasive urological treatment techniques, thermal steam ablation therapy has gradually become one of the mainstream treatment options for benign lesions such as benign prostatic hyperplasia (BPH) due to its advantages of minimal tissue damage and short recovery period. This technique achieves thermal coagulation and necrosis of lesion tissue through precise delivery of high-temperature steam, which can effectively relieve urinary tract obstruction symptoms while preserving organ function to the maximum extent, making it especially suitable for elderly patients or those with underlying diseases.

[0003] In existing technologies, steam therapy systems adopt a modular design architecture of "energy device + disposable treatment instrument". The hot steam therapy instrument integrates three core components: a steam generating unit, a puncture power component, and a temperature-controlled transmission pipeline. The steam generating unit rapidly generates high-temperature steam; the puncture power component drives the cannula to achieve needle insertion; and the transmission pipeline adopts a multi-layer composite structure to ensure stable delivery of steam temperature and pressure.

[0004] In a single treatment session, the hot steam therapy device requires a puncture needle to be inserted into the patient's body to deliver steam to the affected area for treatment. After the treatment is completed, the entire steam therapy device needs to be discarded to avoid cross-infection. This results in a significant increase in the cost of consumables during a single treatment session, keeping the overall treatment cost high. Summary of the Invention

[0005] The purpose of this invention is to provide a steam therapy system and steam supply device to solve the problem in the prior art that a large number of consumables need to be discarded after each treatment, resulting in a large proportion of consumable costs during the treatment process and high treatment costs.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] In a first aspect, this application provides a steam therapy system comprising:

[0019] Optionally, the groove sidewall of the snap-fit ​​groove has a lubricating layer.

[0020] Optionally, the first slot is arc-shaped and has an elastic limiting member on one side near the insertion end, the elastic limiting member being used to engage the conveying head with one end of the first slot.

[0021] Optionally, a valve frame is provided within the airway, the valve frame having a one-way hole communicating with the airway, and a valve plate is rotatably connected to the valve frame. The valve plate adheres to the valve frame to seal the one-way hole, and when steam flows into the puncture needle within the airway, it pushes the valve plate open, thereby opening the one-way hole; and / or,

[0022] The catheter includes:

[0023] Endoscope tube, used to insert the lens;

[0024] A puncture tube is provided in the endoscope tube for inserting the puncture needle;

[0025] A guide tube is fitted over the outside of the endoscope tube and the puncture tube;

[0026] A cleaning connector is provided in the guide tube. The cleaning connector is connected to the endoscope tube and is provided with an inlet tube and an outlet tube to rinse the lens inside the endoscope tube.

[0027] Secondly, this application provides a steam supply device, which includes:

[0028] A steam pipe is disposed in the housing of the steam therapy system as described in claims 1 to 7, the steam pipe having a water inlet and a steam outlet, the steam outlet being connected to the delivery pipe, and the water inlet being used to inject sterile water;

[0029] An energy coupler is detachably connected to the housing and correspondingly configured with the steam pipe to heat the sterile water in the steam pipe to form sterile steam.

[0030] Optionally, the energy coupler includes:

[0037] The beneficial effects of this invention are:

[0038] Firstly, before treatment, the connecting shell is installed onto the housing, and the catheter is connected to the housing. The connecting assembly is then connected to the connecting part inside the housing, ensuring a sealed connection between the airway and the delivery head. During treatment, the puncture needle is inserted into the affected area. The steam supply assembly delivers high-temperature steam through the delivery pipe. The high-temperature steam passes through the delivery head and airway into the puncture needle, and is then guided to the affected area, thus successfully achieving ablation treatment. After treatment, the connecting shell and housing are disassembled, and the connecting assembly and connecting part are separated, allowing the catheter to be separated from the housing. For subsequent treatments, only a new catheter and puncture needle need to be replaced; the housing and the connecting parts inside the housing can be reused. Therefore, when using this steam therapy system, by setting the housing and connecting shell to be detachable, and the puncture needle to be detachably connected to the connecting part through the connecting component, it is possible that after the treatment is completed, only low-cost consumables such as catheters and puncture needles need to be discarded, while the housing and connecting part can be reused. This effectively reduces the number of consumables that need to be discarded in a single treatment, reduces the proportion of consumable costs in a single treatment, and thus effectively reduces treatment costs.

[0039] Secondly, when the steam supply device is in use, by setting the energy coupler to correspond with the steam pipe, after injecting sterile water into the steam pipe, the energy coupler is connected to the power supply to heat the steam pipe, so that the sterile water vaporizes to form sterile steam. The sterile steam can enter the delivery pipe through the air inlet and be delivered to the affected area by the steam therapy system for treatment. Attached Figure Description

"Below," "below," and "under" the second feature includes the first feature being directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0062] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0063] like Figures 1 to 8 As shown, the present invention provides a steam therapy system and a steam supply device.

[0064] Reference Figures 1 to 4 The steam therapy system includes a housing 1, a delivery pipe 2, a connecting part 3, a connecting shell 4, a conduit 5, a connecting assembly 6, and a puncture needle 7. The delivery pipe 2 is located inside the housing 1, with one end connected to a steam supply device and the other end having a delivery head 21. The connecting part 3 is located inside the housing 1, and the delivery head 21 is snapped into the connecting part 3. The connecting shell 4 is detachably connected to the housing 1. The conduit 5 passes through the connecting shell 4. The connecting assembly 6 is located in the connecting shell 4 and partially extends into the housing 1, and is detachably connected to the connecting part 3. The connecting assembly 6 has an airway 61 that is sealed and communicates with the delivery head 21. The puncture needle 7 passes through the conduit 5 and is fixedly connected to the connecting assembly 6. One end of the puncture needle 7 is sealed and communicates with the airway 61, and the other end is used for puncture.

[0065] Before treatment, the connecting shell 4 is installed onto the housing 1, and the conduit 5 is connected to the housing 1. The connecting assembly 6 is then connected to the connecting part 3 inside the housing 1, ensuring a sealed connection between the airway 61 and the delivery head 21. During treatment, the puncture needle 7 is inserted into the affected area. The steam supply assembly delivers high-temperature steam through the delivery pipe 2. The high-temperature steam passes through the delivery head 21 and the airway 61 into the puncture needle 7, and is then guided to the affected area, thus successfully achieving ablation treatment. After treatment, the connecting shell 4 is disassembled from the housing 1, and the connecting assembly 6 is separated from the connecting part 3. The conduit 5 can then be separated from the housing 1. For subsequent treatments, only a new conduit 5 and puncture needle 7 need to be replaced. The housing 1 and the connecting part 3 inside the housing 1 can be reused. Therefore, when using this steam therapy system, by setting the housing 1 and the connecting housing 4 to be detachably connected, and the puncture needle 7 to be detachably connected to the connecting part 3 via the connecting component 6, it is possible that after the treatment is completed, only low-cost consumables such as the catheter 5 and the puncture needle 7 need to be discarded, while the housing 1 and the connecting part 3 can be reused. This effectively reduces the number of consumables that need to be discarded in a single treatment, reduces the proportion of consumable costs in a single treatment, and thus effectively reduces treatment costs.

[0066] Specifically, the housing 1 is pistol-shaped, and its front end is detachably connected to the connecting shell 4. This detachable connection can be achieved through snap-fit, screw-fit, or bolt-fit. In this embodiment, the front end of the housing 1 is provided with a threaded section, and the inner wall of the connecting shell 4 is provided with an internal thread capable of threadedly connecting to the threaded section, thus forming a detachable connection through screwing. The specific connection method can be designed according to the actual operational difficulty, and this application does not impose any limitations.

[0067] The connecting shell 4 is fitted onto the conduit 5, and the two can rotate relative to each other. When the connecting shell 4 is aligned with the housing 1, the conduit 5 will also align with the housing 1. The housing 1 contains a channel tube 11, which communicates with the conduit 5 for inserting the endoscope. The conduit 5 includes an endoscope tube 51, a puncture tube 52, a guide tube 53, and a cleaning connector 54. The endoscope tube 51 and the channel tube 11 are nested together for inserting the lens; at least one sealing ring is also provided inside the endoscope tube 51 to seal the gap between the endoscope and the endoscope tube 51. A puncture tube 52 is disposed within the endoscope tube 51 for inserting a puncture needle 7. The puncture tube 52 is fixedly connected to the endoscope tube 51, and the fixing method can be adhesive bonding, fusion welding, etc. A guide tube 53 is sleeved on the outside of the endoscope tube 51 and the puncture tube 52. A cleaning connector 54 is disposed within the guide tube 53. The cleaning connector 54 is connected to the endoscope tube 51 and is provided with an inlet tube 55 and an outlet tube 56 to rinse the lens inside the endoscope tube 51. Both the inlet tube 55 and the outlet tube 56 are provided with tube clamps 57 to control the inlet fluid. The connection and disconnection of tube 55 and drain tube 56 are as follows: When it is necessary to rinse the lens, open the clamp 57 of the inlet tube 55. The end of the inlet tube 55 away from the cleaning connector 54 is installed in the peristaltic pump 101 of the energy platform 10 and connected to the cleaning injection system so that the cleaning fluid is injected into the endoscope tube 51 through the peristaltic pump 101 to rinse the inner diameter lens. At the same time, close the clamp 57 of the drain tube 56. When it is necessary to drain, open the clamp 57 of the drain tube 56 and close the clamp 57 of the inlet tube 55.

[0068] When the connecting shell 4 is connected to the housing 1, the connecting component 6 on the connecting shell 4 is also connected to the housing 1. The connecting component 6 can be connected to the connecting part 3. A drive mechanism 12 can also be provided on the channel pipe 11. The drive mechanism 12 is connected to the connecting part 3 to drive the connecting part 3 to move, thereby pushing the puncture needle 7 to perform a puncture action. The drive mechanism 12 can be a motor with a screw or elastic mechanism to drive the connecting part 3 to move. The specific design can be based on the actual drive requirements, and this application does not limit it. The delivery pipe 2 is set inside the housing 1. It can be a flexible hose. The steam supply device can be set inside or outside the housing 1. One end of the delivery pipe 2 is connected to the steam supply device, and the other end is provided with a delivery head 21. The delivery head 21 is snapped onto the connecting part 3 so that the delivery head 21 remains stationary when the connecting component 6 is installed, so that the delivery head 21 can form a sealed connection with the air passage 61. The end face of the connecting component 6 has a plug-in structure that can be inserted into the housing 1 and locked with the connecting part 3, such as by threaded connection, snap-fit ​​or magnetic locking, so that the connecting component 6 can form a detachable connection with the connecting part 3.

[0069] Optionally, the connecting part 3 has a first slot 31 and a second slot 32, the delivery head 21 is fixed to the first slot 31, and the connecting assembly 6 includes a connecting block 62. The air passage 61 is disposed on the connecting block 62, one side of the connecting block 62 is connected to the puncture needle 7, and the other side has a plug block 63 that is inserted into the second slot 32 and a plug connector 64 that communicates with the air passage 61 and can be sealed and communicated with the delivery head 21.

[0070] Specifically, the connecting part 3 is plate-shaped, with a first slot 31 and a second slot 32 extending through its side. The conveying head 21 passes through the first slot 31 and is engaged and fixed therewith, so that one end of the conveying head 21 can protrude from the connecting part 3. To ensure the sealing of the connection between the air passage 61 and the conveying head 21, a plug 64 protrudes from the side of the connecting block 62 near the connecting part 3. The plug 64 and the connecting block 62 are integrally formed, with one end of the plug 64 communicating with the air passage 61 and the other end able to be inserted into the conveying head 21, thereby ensuring a sealed connection between the air passage 61 and the conveying head 21. The second slot 32 has the same shape as the first slot 31. It allows the insertion block 63 to be inserted and locked to the insertion block 63. The locking method can be snap-locking, adsorption locking, or magnetic locking, so that the insertion block 63 can be fixed together with the connecting part 3 after being inserted into the second slot 32. After the treatment is completed, the insertion block 63 is pulled out from the second slot 32, and the connector 64 is pulled out from the delivery head 21, so that the catheter 5 can be separated from the housing 1.

[0071] Optionally, the second slot 32 extends in an arc shape and has an insertion end 321 and a locking end 322. The cross-sectional area of ​​the insertion end 321 is larger than the cross-sectional area of ​​the locking end 322. The end of the plug block 63 away from the connecting block 62 is provided with a locking connector 631. The cross-sectional area of ​​the locking connector 631 is smaller than the cross-sectional area of ​​the insertion end 321 and larger than the cross-sectional area of ​​the locking end 322.

[0072] Specifically, the second slot 32 is elongated and extends along an arc. The lower end of the second slot 32 serves as the insertion end 321, and the other end serves as the locking end 322. The insertion end 321 is wider, resulting in a larger cross-sectional area of ​​the second slot 32. This cross-sectional area is larger than that of the connector 631, allowing the connector 631 to pass smoothly through the second slot 32 of the insertion end 321. At this time, the connecting shell 4 and the housing 1 also form a mating connection, which can be fixed by thread. Therefore, after the two are mated, the connecting shell 4 can be rotated to fix it to the housing 1. As the connecting shell 4 rotates, it will drive the connecting block 62 and the plug block 63 to rotate synchronously, causing the plug block 63 to turn from the insertion end 321 to the locking end 322 within the second slot 32. At this time, the cross-sectional area of ​​the connector 631 is larger than that of the locking end 322, so the connector 631 can be locked within the second slot 32, thus achieving axial locking of the connector.

[0073] Optionally, the plug block 63 has a snap-fit ​​groove 632, and the connecting part 3 is provided with a locking band 323 along the extension direction of the second slot 32. The width of the locking band 323 at the insertion end 321 is greater than the width at the locking end 322. The width of the snap-fit ​​groove 632 is less than the width of the locking band 323 at the locking end 322 but greater than the width of the locking band 323 at the insertion end 321.

[0074] Specifically, the width refers to the dimension of the plug-in block 63 along its extension direction. A snap-fit ​​groove 632 is provided at the end of the plug-in block 63 away from the connecting block 62, and a locking band 323 is provided at the edge of the second slot 32. The width of the locking band 323 gradually changes along its extension direction, and the width of the locking band 323 is the largest at the insertion end 321. At this time, when the plug-in block 63 is inserted into the second slot 32, the snap-fit ​​groove 632 will not engage with the locking band 323. When the plug-in block 63 rotates to the locking end 322, the width of the locking band 323 at the locking end 322 is smaller, so that a snap-fit ​​engagement is formed in the snap-fit ​​groove 632 at the insertion point of the locking band 323. This restricts the sliding of the plug-in block 63 in the second slot 32, thereby locking the plug-in block 63 at the locking end 322 of the second slot 32. In order to reduce the resistance of the locking groove 632 during rotation, the groove sidewall of the locking groove 632 has a lubricating layer, so that the groove wall of the locking groove 632 and the groove wall of the second locking groove 32 have better smoothness.

[0075] It should be understood that the locking band 323 and the locking connector 631 can be installed simultaneously, or only one of them can be installed for locking. The specific design can be based on the actual locking requirements, and this application does not limit it.

[0076] Optionally, the first slot 31 is arc-shaped and an elastic limiting member 33 is provided on the side near the insertion end 321. The elastic limiting member 33 is used to clamp the conveying head 21 to one end of the first slot 31.

[0077] Specifically, the arc center of the first slot 31 is the same as the arc center of the second slot 32. An elastic limiting member 33, such as an elastic buckle, is provided at the lower end of the first slot 31. It can span across the first slot 31 and engage with the conveyor head 21. Before the connecting block 62 is installed, the conveyor head 21 is engaged with the lower end of the first slot 31, so that the connector 64 can be smoothly engaged with the conveyor head 21. When the connecting block 62 rotates, it will drive the conveyor head 21 to rotate synchronously through the connector 64. The conveyor head 21 will squeeze the elastic limiting member 33 and separate it from the limiting member, so that the conveyor head 21 rotates synchronously to the upper end of the first slot 31.

[0078] To ensure that the airway 61 does not contaminate the internal structure of the machine housing 1 due to backflow during treatment, a one-way valve structure can be installed in the airway 61 so that steam can only flow into the puncture needle 7 along the delivery head 21, the connector 64 and the airway 61.

[0079] Optionally, a valve frame 611 is provided in the air passage 61. The valve frame 611 has a one-way hole 612 communicating with the air passage 61. A valve plate 613 is rotatably connected to the valve frame 611. The valve plate 613 adheres to the valve frame 611 to close the one-way hole 612. When steam flows in the air passage 61, it pushes the valve plate 613 open and opens the one-way hole 612.

[0080] Specifically, an installation cavity 614 is provided in the connecting block 62, and the air passage 61 passes through the installation cavity 614. A valve frame 611 is fixedly installed on the cavity wall of the installation cavity 614 near the plug 64. The valve frame 611 can be embedded or glued to the cavity wall of the installation cavity 614. A through hole is provided in the middle of the valve frame 611 as a one-way hole 612, which communicates with the air passage 61. A valve plate 613 is hinged to the upper side of the valve frame 611. The hinge structure is made of flexible material.

[0081] The valve frame 611 can be a ring magnet, or a ring magnet with a non-metallic layer wrapped around it. The valve plate 613 is made of a sheet magnet or a non-metallic plate with a ring magnet nested inside. The magnetic poles on opposite sides of the two are opposite, so that when no steam is input, the valve plate 613 and the valve frame 611 are attracted and adhered to each other to close the one-way orifice 612. When steam backflow occurs, the steam will directly push the valve plate 613 closer to the valve frame 611, thereby closing the one-way orifice 612. In this way, the steam can only flow along the air passage 61 to the puncture needle 7.

[0082] It should be understood that only one magnet may be provided in the valve plate 613 and the valve frame 611, while the other may be made of a material that can be attracted by the magnet. In other embodiments, the attraction may also be achieved by using a suction cup. In order to achieve the closure of the one-way hole 612, an elastic structure such as a torsion spring may be provided in the hinge structure to make the valve plate 613 fit against the valve frame 611, thereby increasing the adhesion between the valve plate 613 and the valve frame 611. The elastic structure may also be provided in the mounting cavity 614, which is directly connected to the side of the valve plate 613 away from the hinge, and can also use elastic force to pull the valve plate 613 against the valve frame 611 to maintain the closure of the one-way hole 612.

[0083] Reference Figure 1 , Figure 2 , Figures 5 to 8The steam supply device includes a steam pipe 8 and an energy coupler 9. The steam pipe 8 is installed in the housing 1 of the steam therapy system described above. The steam pipe 8 has a water inlet and a steam outlet. The steam outlet is connected to the delivery pipe 2, and the water inlet is used to inject sterile water. The energy coupler 9 is detachably connected to the housing 1 and is correspondingly arranged with the steam pipe 8 to heat the sterile water in the steam pipe 8 to form sterile steam.

[0084] Specifically, the housing 1 is pistol-shaped, and a fixing sleeve 13 can be installed inside the handle section. The steam pipe 8 is embedded in the fixing sleeve 13, with both ends of the steam pipe 8 opening vertically upwards. One end of the steam pipe 8 serves as a steam port, connected to the delivery pipe 2. A pressure sensor 81 can be installed at the steam port to monitor the steam pressure. The other end of the steam pipe 8 serves as a water inlet. A water inlet channel 131 is provided inside the fixing sleeve 13. One end of the water inlet channel 131 is connected to the water inlet, and the other end is provided with a water inlet connector 132, which is connected to the water inlet pipe 133. Luer connectors are provided at both ends of the water inlet pipe 133 to connect to the water inlet connector 132 and the syringe 134, respectively. The steam therapy system can also be configured with an energy platform 10, on which an injection pump is installed. The syringe 134 is installed on the injection pump, and the injection pump causes the syringe 134 to continuously inject sterile water into the steam pipe 8 through the water inlet pipe 133 and the water inlet channel 131.

[0085] The energy coupler 9 can be plugged into the handle section of the housing 1. It can be electrically connected to the energy platform 10 and generates sterile steam by heating the steam pipe 8 to vaporize the sterile water inside the steam pipe 8. The energy coupler 9 can be heated by a heating module or by forming a radio frequency field using a radio frequency structure.

[0086] When in use, the steam supply device is configured by matching the energy coupler 9 with the steam pipe 8. After injecting sterile water into the steam pipe 8, the energy coupler 9 is powered on to heat the steam pipe 8, causing the sterile water to vaporize and form sterile steam. The sterile steam can enter the delivery pipe 2 through the air inlet and be delivered to the affected area by the steam therapy system for treatment.

[0087] Optionally, the energy coupler 9 includes a base 91, a cable 92, and an RF coil 93. The base 91 is detachably connected to the housing 1; the cable 92 is disposed on the base 91 and electrically connected to a power source; the RF coil 93 is disposed on the base 91 and can be sleeved on the outside of the steam pipe 8 and electrically connected to the cable 92. The RF coil 93 is used to heat the sterile water in the steam pipe 8 to form sterile steam.

[0088] Specifically, the base 91 can be plugged into the handle section of the housing 1. Electrical components such as an electrical interface 14, circuit board 15, and buttons 16 can also be installed on the handle section of the housing 1. Multiple sets of gold fingers 911 are provided on the base 91 to connect to the corresponding electrical components. The radio frequency coil 93 can be plugged into the outside or inside of the steam pipe 8. One end of the cable 92 is electrically connected to the radio frequency coil 93, and the other end is connected to the energy platform 10 to be powered. When steam is needed, the radio frequency coil 93 generates a radio frequency field, creating an eddy current heating effect, causing the sterile water in the steam pipe 8 to boil and generate hot steam. The plugging and connection between the base 91 and the housing 1 allows the circuit and water circuits to be separated. The circuit can be directly covered with a sterile sleeve, thus avoiding sterilization and facilitating reuse.

[0089] To improve heating efficiency, the steam pipe 8 can optionally be a coil, and the radio frequency coil 93 can be sleeved on the outside of the coil. The energy coupler 9 also includes a temperature sensing shaft 94. The temperature sensing shaft 94 is disposed on the base 91 and inserted into the coil, and multiple temperature sensors 95 are spaced apart on the temperature sensing shaft 94 to detect the temperature of the steam pipe 8.

[0090] The temperature sensing shaft 94 can be made of high-temperature resistant heat-insulating material. It is adapted to the shape of the steam pipe 8 and inserted into the middle of the coil. A temperature sensor 95 is installed near the steam inlet, and another temperature sensor 95 is installed in the middle of the shaft to detect temperature changes at the two locations respectively. It should be understood that the number and location of the temperature sensors 95 can be designed according to the actual temperature detection requirements, and are not limited to the number and location shown in the example above.

[0091] To improve heating efficiency, a heat insulation layer 96 is provided on the outside of the radio frequency coil 93 to block heat transfer to the housing 1. On the one hand, this allows the heat to be concentrated for heating and evaporating sterile water, reducing the rate of heat loss and thus improving heating efficiency. On the other hand, it also reduces the rate at which heat is transferred to the housing 1, so that the temperature of the handle section of the housing 1 is kept within a suitable range during the operation of the physician, so as to avoid interfering with the physician's operation.
