Description

Technical Field

[0001] This invention relates to the field of therapeutic devices, and more specifically to a prostate therapeutic device. Background Technology

[0002] In prostate treatment, the diseased tissue is mainly removed using surgical resection devices. However, this traditional treatment method has several significant drawbacks: the surgical procedure is extremely complex, requiring surgeons to completely remove the diseased tissue while avoiding damage to surrounding important neurovascular bundles, which demands a very high degree of precision in the surgical operation; the entire surgical process is time-consuming, causes significant trauma to the body, increases the patient's anesthesia risks and intraoperative bleeding, and prolongs postoperative recovery time.

[0003] While new prostate treatment devices have emerged recently due to industry development, they still suffer from cumbersome operation and poor safety, posing potential risks. Therefore, it is necessary to provide a prostate treatment device that is simple and convenient to operate, less invasive, and offers improved safety. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the present invention aims to provide a prostate treatment device that is simple and convenient to operate, improves safety, reduces trauma to the body, and helps patients recover quickly.

[0005] The objective of this invention is achieved through the following technical solution: A prostate treatment device includes a gripper, a steam puncture tube, a steam tube drive device, a delivery tube device, a liquid delivery device, and a heating device. The steam puncture tube is provided with a puncture working end for puncture and steam outflow. The steam puncture tube is movably installed within the gripper. The steam tube drive device drives the steam puncture tube to move so that the puncture working end enters and exits the gripper. The delivery tube device is in communication with the steam puncture tube. The liquid delivery device delivers liquid to the delivery tube device. The heating device heats the liquid flowing through the delivery tube device to form steam.

[0006] The conveying pipe device includes a spiral pipe, at least a portion of which extends in a spiral shape, and the heating device is disposed outside the spiral pipe.

[0007] The heating device includes a radio frequency coil, which is spirally wound around the periphery of a spiral tube.

[0008] The liquid delivery device includes a syringe and a piston drive device; a piston is movably installed inside the syringe, and the piston drive device is used to drive the piston to move along the syringe; the syringe is connected to a delivery tube device.

[0009] The piston drive device includes an electric cylinder.

[0010] The gripper is provided with an observation cavity for the endoscope to pass through, and the prostate treatment device also includes a solution delivery device for delivering a solution to the observation cavity.

[0011] The gripper is provided with a valve body, the valve body is provided with a valve cavity, the solution delivery device is connected to the observation liquid outlet cavity through the valve cavity, and the valve body is provided with a valve flap for sealing cooperation with the endoscope.

[0012] The prostate treatment device also includes a solution recovery device, which is connected to the valve chamber.

[0013] The steam puncture tube is provided with a steam chamber, and the puncture working end is provided with a steam output unit, the steam output unit including a steam hole communicating with the steam chamber.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention provides a prostate treatment device that combines a gripper, a steam puncture tube, a steam tube drive device, a delivery tube device, a liquid delivery device, and a heating device. The steam tube drive device moves the steam puncture tube, allowing its working end to extend from the gripper for puncture. The heating device heats the liquid flowing through the delivery tube, converting it into steam, which is then injected into the prostate lesion through the steam puncture tube to achieve ablation treatment. This makes the treatment simple and convenient, easy for operators to learn, and results in a smaller wound from the working end of the steam puncture tube, significantly reducing trauma to the patient and effectively shortening recovery time. After treatment, the steam tube drive device moves the steam puncture tube back into the gripper, reducing the risk of accidental puncture and improving safety. Attached Figure Description

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-18 As shown, a prostate treatment device includes a gripper 120, a steam puncture tube 110, a steam tube drive device 150, a delivery tube device 240, a liquid delivery device 200, and a heating device 230. The steam puncture tube 110 is provided with a puncture working end 114 for puncture and steam outflow. The steam puncture tube 110 is movably installed within the gripper 120. The steam tube drive device 150 is used to drive the steam puncture tube 110 to move so that the puncture working end 114 enters and exits the gripper 120. The delivery tube device 240 is connected to the steam puncture tube 110. The liquid delivery device 200 is used to deliver liquid to the delivery tube device 240. The heating device 230 is used to heat the liquid flowing through the delivery tube device 240 to form steam.

[0019] During treatment, the operator holds the gripper 120 and inserts it into the prostate. The steam pipe drive device 150 drives the steam puncture tube 110 forward, so that the puncture working end 114 of the steam puncture tube 110 extends from the gripper 120 and punctures the prostate lesion tissue. At this time, the liquid pusher 200 delivers sterile water and other liquids to the delivery tube device 240. The heating device 230 heats the liquid flowing through the delivery tube device 240 to form steam. The high-temperature steam can flow through the delivery tube device 240 to the steam puncture tube 110, and then be output through the puncture working end 114 of the steam puncture tube 110 and injected into the prostate lesion tissue to achieve ablation treatment. After treatment, the steam puncture tube 110 is moved backward by the steam pipe drive device 150, so that the puncture working end 114 of the steam puncture tube 110 moves into the holding member 120. This allows the steam puncture tube 110 to be retracted, avoiding damage to the urethra during withdrawal and reducing the risk of accidental puncture injury caused by the exposed puncture working end 114. Therefore, the prostate treatment device provided by this invention, by combining the holding member 120, steam puncture tube 110, steam pipe drive device 150, delivery tube device 240, liquid pushing device 200, and heating device 230, only requires holding the holding member 120, and the steam pipe drive device 150 drives the steam puncture tube 110. The procedure involves moving the steam tube 110 for puncture, supplying steam to the tube via the delivery device 240 and heating device 230, and then injecting steam into the prostate lesion tissue through the steam tube 110 to achieve ablation treatment. This makes the treatment simple and convenient, easy for operators to learn, and the wound formed by the puncture working end 114 of the steam tube 110 is small, which can significantly reduce trauma to the patient's body and thus effectively shorten the patient's recovery time. After the treatment is completed, the steam tube drive device 150 drives the steam tube 110 to move, so that the puncture working end 114 of the steam tube 110 moves into the holding member 120, which can reduce the accidental puncture injury caused by the puncture end of the steam tube 110 and improve the safety of use.

[0020] The conveying pipe device 240 includes a spiral pipe 241, at least a portion of which extends in a spiral shape. The heating device 230 is disposed outside the spiral pipe 241. In use, liquid is conveyed to the conveying pipe device 240 by a liquid pushing device 200. As the liquid flows through the spiral pipe 241, the heating device 230 heats the liquid flowing through the spiral pipe 241 to form steam.

[0021] The spiral tube 241 is a one-piece molded steel tube. By using a one-piece molded steel tube for the spiral tube 241, high heating efficiency can be ensured, while durability and safety are enhanced, making it suitable for long-term medical use.

[0022] Preferably, the heating device 230 includes a radio frequency coil, which is spirally wound around the periphery of the spiral tube 241. In use, the heating device 230 is energized to generate a magnetic field. Eddy currents are generated inside the spiral tube 241 under electromagnetic induction. During the flow of these eddy currents, the spiral tube 241 generates heat, rapidly heating the liquid flowing through it to form steam, which then flows from the delivery tube device 240 to the steam puncture tube 110. By using a spiral tube 241 with at least a portion of its extension trajectory spiraled in the delivery tube device 240, and employing a radio frequency coil spirally wound around the periphery of the spiral tube 241 for the electromagnetic heating device 230, electromagnetic induction heating can be achieved. This results in more uniform and efficient heating, improved thermal efficiency, and reduced heat conduction losses in traditional heating methods. The liquid can quickly absorb sufficient heat, achieving rapid and uniform vaporization to quickly generate steam. This extends the liquid heating path, ensuring that the liquid continuously flowing through this path can be heated and continuously generate steam, providing a continuous and stable high-temperature steam source for prostate treatment, ensuring both treatment effectiveness and safety.

[0023] The heating frequency of the radio frequency coil is 50K to 600KHz, and the heating efficiency can be further accelerated by setting the heating efficiency of the radio frequency coil to the range of 50K to 600KHz.

[0024] Of course, in addition to the above, the heating device 230 can also be a heating tube or other heating device, as long as it can heat the liquid flowing through the conveying pipe device 240 to form steam. However, using a radio frequency coil for the heating device 230 is the most preferred embodiment of the present invention, which can realize electromagnetic induction heating, making the heating more uniform and efficient, and improving thermal efficiency.

[0025] The prostate treatment device also includes a first temperature detection device 250 and a second temperature detection device 260. The first temperature detection device 250 is used to detect the temperature of the steam in the delivery tube device 240, and the second temperature detection device 260 is used to detect the temperature of the heating device 230. By employing the dual detection devices of the first temperature detection device 250 and the second temperature detection device 260, the temperature of the steam can be detected by the first temperature detection device 250, so that the steam can be stabilized within a predetermined range of 90°C to 105°C, so that the diseased tissue cells die instantly, but excessive carbonization or ineffective heating is avoided. The temperature of the heating device 230 itself is detected by the second temperature detection device 260 to prevent the heating device 230 from overheating and being damaged or affecting the steam quality. Therefore, the dual detection devices can accurately detect the steam temperature, laying the foundation for effective tissue ablation, ensuring the stability and safety of the treatment steam, and protecting the heating source itself to ensure the durability and reusability of the system.

[0026] The prostate treatment device also includes a control device, which controls the operation of the heating device 230 based on the temperatures detected by the first temperature detection device 250 and the second temperature detection device 260. During operation, the control device receives feedback signals from the first and second temperature detection devices 250 and dynamically adjusts the power or on / off state of the heating device 230 based on real-time temperature data, achieving intelligent control of the heating process. This significantly improves the system's intelligence level and treatment accuracy, enhancing the controllability and safety of the treatment process.

[0027] Both the first temperature detection device 250 and the second temperature detection device 260 include thermocouples so that the temperature of the corresponding object can be detected by the thermocouples.

[0028] The first temperature detection device 250 and the second temperature detection device 260 can also be any temperature detection device available on the market, as long as it can be used to detect the temperature of the corresponding object.

[0029] The liquid delivery device 200 includes a syringe 210 and a piston drive device 220. A piston 211 is movably mounted inside the syringe 210, and the piston drive device 220 drives the piston 211 to move along the syringe 210. The syringe 210 is connected to a delivery tube device 240. During use, the piston drive device 220 drives the piston 211 forward, using the piston 211 to push sterile water or other liquids from the syringe 210 to the delivery tube device 240. By combining the syringe 210 and the piston drive device 220 into the liquid delivery device 200, the piston drive device 220 can drive the piston 211 to move, and the piston 211 can push the liquid in the syringe 210 to the delivery tube device 240, eliminating the need for manual injection of the syringe 210, reducing operator involvement, and alleviating the operator's workload.

[0030] The delivery tube device 240 includes a pure water inlet pipe 242, which connects the spiral tube 241 and the syringe 210. The piston drive device 220 drives the piston 211 inside the syringe 210 to move forward. The movement of the piston 211 pushes sterile water or other liquids from the syringe 210 to the pure water inlet pipe 242, and then through the pure water inlet pipe 242 into the spiral tube 241. This structure is simple, reliable, and ensures smooth liquid delivery.

[0031] Preferably, the pure water inlet pipe 242 is connected to the syringe 210 via a Luer connector to facilitate the connection between the pure water inlet pipe 242 and the syringe 210.

[0032] The delivery tube device 240 also includes a connecting tube 244, through which the steam puncture tube 110 is connected to the spiral tube 241. The steam generated by heating the spiral tube 241 can flow to the connecting tube 244 and be output from the steam puncture tube 110 to the prostate lesion tissue via the connecting tube 244.

[0033] Preferably, the connecting pipe 244 includes a steel wire flexible hose. Specifically, the connecting pipe 244 is a corrugated steel wire flexible hose. By using a steel wire flexible hose for the connecting pipe 244, it has good flexibility, can be matched with the position of the steam piercing pipe 110 for angle adjustment and spatial arrangement, and improves the flexibility and convenience of connection.

[0034] The piston drive device 220 is an electric cylinder. By using an electric cylinder for the piston drive device 220, the piston 211 can be moved while the cost can be effectively controlled.

[0035] The steam puncture tube 110 is provided with a steam chamber 116, and the puncture working end 114 is provided with a steam output unit, which includes a steam hole 115 communicating with the steam chamber 116. In use, steam flows from the delivery pipe device 240 to the steam chamber 116 of the steam puncture tube 110, and flows out through the steam hole 115 of the steam output unit.

[0036] Preferably, the puncture working end 114 is provided with a plurality of steam output units arranged circumferentially. Each steam output unit includes multiple steam holes 115 communicating with the steam chamber 116. During treatment, steam can flow out from multiple directions through the steam holes 115 of the plurality of steam output units, thereby improving the treatment effect.

[0037] The puncture working end 114 includes an end tube section 118 and a puncture head 117; the puncture head 117 is used for puncture and is located at the end of the end tube section 118; the steam output unit is located on the tube wall of the end tube section 118. During treatment, the prostate lesion tissue can be punctured with the puncture head 117, and then steam can be injected into the prostate lesion tissue through the steam holes 115 of each steam output unit to achieve ablation treatment.

[0038] The steam pipe drive device 150 is installed inside the gripper 120.

[0039] The steam tube driving device 150 includes an electromagnetic coil device 140 and a magnet device 130. The magnet device 130 is used to move when the electromagnetic coil device 140 is energized. The steam puncture tube 110 is fixedly connected to the magnet device 130 and can move with the magnet device 130. During treatment, the electromagnetic coil device 140 can be connected to a positive current to generate a magnetic field with the same polarity as the magnet device 130. The magnet device 130 moves forward under the repulsive force of the magnetic field. Since the steam puncture tube 110 is fixedly connected to the magnet device 130, the steam puncture tube 110 moves forward synchronously with the magnet device 130, so that the puncture working end 114 of the steam puncture tube 110 extends smoothly from the holding member 120 and punctures the prostate lesion tissue. Then, high-temperature steam is injected through the steam hole 115 of the steam puncture tube 110 to complete the ablation of the prostate lesion tissue and realize ablation treatment. After treatment, the electromagnetic coil device 140 is connected to a reverse current to generate a magnetic field with the opposite polarity to that of the magnet device 130. Under the attraction of the magnetic field, the magnet device 130 moves backward, and the steam puncture tube 110 moves backward synchronously with the magnet device 130, so that the puncture working end 114 of the steam puncture tube 110 moves into the holding member 120, thereby retracting the puncture working end 114 of the steam puncture tube 110, avoiding damage to the urethra during withdrawal, and reducing the risk of accidental puncture injury caused by the exposed puncture working end 114 of the steam puncture tube 110.

[0040] To further optimize its performance, the gripper 120 is equipped with a pin retraction button. By triggering the pin retraction button, the electromagnetic coil device 140 can be controlled to connect to forward or reverse current, thereby further improving the ease of operation.

[0041] The magnet device 130 includes a power magnet 131 and a magnet bracket 132. The power magnet 131 is mounted on the magnet bracket 132, and the magnet bracket 132 is provided with a mounting groove 133. The steam puncture tube 110 is inserted into the mounting groove 133. By combining the power magnet 131 and the magnet bracket 132 into the magnet device 130, it is convenient to install and replace components. The mounting groove 133 on the magnet bracket 132 provides a reliable insertion position for the steam puncture tube 110, ensuring that the steam puncture tube 110 can move synchronously and stably when the magnet device 130 moves, while also facilitating the installation of the steam puncture tube 110.

[0042] The magnet bracket 132 includes a main frame, with a first baffle 134 at one end and a second baffle 135 at the other end. The power magnet 131 is mounted on the main frame and located between the first baffle 134 and the second baffle 135. By employing this structure, the first baffle 134 and the second baffle 135 at both ends of the main frame effectively limit the movement of the power magnet 131, preventing relative axial movement between the power magnet 131 and the main frame, and ensuring the stability of the installation between the power magnet 131 and the main frame.

[0043] The electromagnetic coil device 140 includes a coil support 141 and an electromagnetic coil wound on the coil support 141. A passage cavity is formed on the coil support 141 for the magnet device 130 to pass through. By adopting this structure, when the magnet device 130 moves under the influence of the magnetic field generated by the energized electromagnetic coil device 140, the passage cavity provides a movement range for the magnet device 130, allowing it to move smoothly within the coil support 141, resulting in a more compact structure and reduced volume.

[0044] In this embodiment, the coil support 141 is fixedly connected to the gripper 120.

[0045] The prostate treatment device may also include a steam button device for controlling the operation of the liquid delivery device 200 and the heating device 230. By triggering the steam button device, the operation of the liquid delivery device 200 and the heating device 230 can be controlled synchronously so that the steam puncture tube 110 generates output steam, thereby further improving the ease of operation.

[0046] The steam puncture tube 110 includes a main body 111, a first tube segment 112, and a second tube segment 113. The first tube segment 112 is located at one end of the main body 111, and the second tube segment 113 is located at the other end of the main body 111. The second tube segment 113 is connected to the delivery tube device 240. Specifically, the second tube segment 113 is connected to the connecting pipe 244 of the delivery tube device 240.

[0047] The end tube segment 118 is disposed on the first tube segment 112. The puncture head 117 is conical, and its diameter gradually decreases from the end near the first tube segment 112 to the end away from the first tube segment 112, so as to facilitate puncture using the tip of the puncture head 117.

[0048] From the end of the first pipe segment 112 closest to the main pipe 111 to the end furthest from the main pipe 111, the first pipe segment 112 gradually extends in a direction away from the main pipe 111. From the end of the second pipe segment 113 closest to the main pipe 111 to the end furthest from the main pipe 111, the second pipe segment 113 gradually extends in a direction away from the main pipe 111; from the end closest to the main pipe 111 to the end furthest from the main pipe 111, the extension direction of the second pipe segment 113 is opposite to the extension direction of the first pipe segment 112. This structure facilitates manufacturing and connection.

[0049] The steam puncture tube 110 is made of PEEK material. By making the steam puncture tube 110 of PEEK material, it can have good biocompatibility, ensuring safe contact with human tissue, and has high temperature resistance, which can remain stable at steam temperature of 95-105°C without decomposition or deformation, and ensure structural stability.

[0050] The gripper 120 is provided with an observation fluid outlet cavity 124 for the endoscope to pass through. During treatment, the endoscope can be first inserted into the observation fluid outlet cavity 124 to facilitate observation of the puncture position of the prostate. Then, the steam puncture tube 110 is driven forward by the steam pipe driving device 150 to puncture the prostate lesion tissue and inject steam into the lesion tissue.

[0051] The observation chamber 124 penetrates the front end of the gripper 120. The gripper 120 is provided with an internal cavity 121, and the steam puncture tube 110 is movably installed in the internal cavity 121. Both the observation chamber 124 and the internal cavity 121 penetrate the front end of the gripper 120.

[0052] The grip 120 includes a gun head 122 and a tube 123; the tube 123 is plugged into the gun head 122.

[0053] The prostate treatment device also includes a solution delivery device 310 for delivering a solution to the observation cavity 124. When the steam puncture tube 110 is inserted and steam is injected into the prostate lesion tissue, the solution delivery device 310 delivers a solution (e.g., physiological saline) to the observation cavity 124. The solution flows through the observation cavity 124 to the normal tissue near the lesion tissue to prevent the normal tissue from being killed.

[0054] The gripper 120 is provided with a valve body 10, and the valve body 10 is provided with a valve cavity 11. The solution delivery device 310 is connected to the observation outlet cavity 124 through the valve cavity 11. Preferably, the solution delivery device 310 includes a saline supply device 311, a water pump 312, and a saline inlet pipe 313; the saline supply device 311 is connected to the saline inlet pipe 313 through the water pump 312. The saline inlet pipe 313 is connected to the valve cavity 11. When the water pump 312 is working, the physiological saline supplied by the saline supply device 311 is pumped to the saline inlet pipe 313 by the water pump 312, and then enters the valve cavity 11 through the saline inlet pipe 313, and then enters the observation outlet cavity 124 through the valve cavity 11.

[0055] The saline supply device 311 includes a saline bottle and a saline supply pipe. The saline supply pipe is connected between the saline bottle and the water pump 312. When the water pump 312 is working, the physiological saline in the saline bottle flows to the saline supply pipe and then flows to the saline inlet pipe 313 via the water pump 312.

[0056] The prostate treatment device also includes a solution recovery device 320, which is connected to the valve chamber 11, allowing excess saline solution in the valve chamber 11 to flow to the solution recovery device 320. Specifically, the solution recovery device 320 includes a saline outlet pipe 321 and a recovery container 322. The saline outlet pipe 321 connects the recovery container 322 and the valve chamber 11, allowing excess saline solution in the valve chamber 11 to flow through the saline outlet pipe 321 to the recovery container 322 for recovery.

[0057] The valve body 10 is provided with a valve disc 20, which is adapted to be in a closed state under its own elastic force. The valve disc 20 is used for endoscope insertion and for sealing cooperation with the endoscope. When the endoscope is not inserted into the holding member 120, the valve disc 20 is in a closed state under its own elastic force to prevent saline from leaking out through the valve disc 20. When the endoscope is inserted into the holding member 120, the endoscope is inserted into the valve disc 20 and passes through the valve disc 20 into the observation fluid chamber 124. Because the valve disc 20 and the endoscope are sealed together, saline can be prevented from seeping out between the valve disc 20 and the endoscope, thus improving the sealing effect.

[0058] The valve disc 20 includes a first elastic opening / closing portion 21 and a second elastic opening / closing portion 22; the first elastic opening / closing portion 21 and the second elastic opening / closing portion 22 are located within the valve cavity 11; when the endoscope is inserted into the valve disc 20, the first elastic opening / closing portion 21 and the second elastic opening / closing portion 22 are pushed against each other by the endoscope to form a passageway for the endoscope to pass through; when the valve disc 20 is in the closed state, the first elastic opening / closing portion 21 and the second elastic opening / closing portion 22 abut against each other under the action of their respective elastic forces to form a liquid-sealed fit (e.g., Figure 15 (As shown).

[0059] During the insertion of the endoscope into the holder 120, the endoscope is first moved towards the valve disc 20. The end of the endoscope pushes against the first elastic opening and closing part 21 and the second elastic opening and closing part 22, causing the first elastic opening and closing part 21 and the second elastic opening and closing part 22 to elastically deform and move away from each other. This creates a passageway between the first elastic opening and closing part 21 and the second elastic opening and closing part 22 for the endoscope to pass through, facilitating the movement of the endoscope within the valve disc 20. At the same time, the valve disc 20 forms a liquid-sealed fit with the outer wall of the endoscope, preventing solution leakage. When the endoscope is removed from the holder 120, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 return to their original position under the action of their respective elastic forces, forming a liquid-sealed fit. This keeps the valve disc 20 in the closed state, blocking water passage and improving the sealing effect.

[0060] The valve disc 20 further includes a first side-mounted connecting portion 24 and a second side-mounted connecting portion 25. The first side-mounted connecting portion 24 is disposed between one end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22; the second side-mounted connecting portion 25 is disposed between the other end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22. By disposing the first side-mounted connecting portion 24 between one end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22, and disposing the second side-mounted connecting portion 25 between the other end of the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22, the structural strength and integrity of the valve disc 20 are enhanced, preventing the first elastic opening and closing portion 21 and the second elastic opening and closing portion 22 from becoming misaligned or falling off during repeated opening and closing, ensuring its sealing reliability during long-term use, and improving the durability of the product.

[0061] The valve disc 20 also includes a support plate 26. The first elastic opening and closing part 21 and the second elastic opening and closing part 22 are disposed on the support plate 26. The support plate 26 is provided with a guide hole 29 for the endoscope to pass through. When the endoscope is moved into the holder 120, the end of the endoscope first passes through the guide hole 29, then pushes open the first elastic opening and closing part 21 and the second elastic opening and closing part 22, and then passes through the passage between the first elastic opening and closing part 21 and the second elastic opening and closing part 22. By adopting the above structure, the assembly process of the valve disc 20 can be simplified. At the same time, the guide hole 29 plays the role of guiding the endoscope, ensuring that the endoscope can push the first elastic opening and closing part 21 and the second elastic opening and closing part 22 along a predetermined path, avoiding jamming or sealing failure caused by deflection, and improving the smoothness and safety of use.

[0062] The valve body 10 is provided with an embedding groove 40, and the edge of the support plate 26 is embedded in the embedding groove 40. By adopting the above structure, the installation of the valve disc 20 can be facilitated, and the stability of the installation between the valve disc 20 and the valve body 10 can be improved.

[0063] The support plate 26 includes a main body 27 and a protrusion 28. The protrusion 28 is disposed on the main body 27, and the first elastic opening / closing part 21 and the second elastic opening / closing part 22 are disposed on the protrusion 28. The embedding groove 40 includes a main groove 41 and a positioning groove 42. The positioning groove 42 communicates with the main groove 41. The protrusion 28 is embedded in the positioning groove 42, and the main body 27 is embedded in the main groove 41. Specifically, the diameter of the main body 27 is larger than the diameter of the protrusion 28. By embedding the protrusion 28 in the positioning groove 42 and the main body 27 in the main groove 41, the accuracy of the valve disc 20 installation and positioning can be improved, and the stability of the valve disc 20 fixation can be improved.

[0064] The valve disc 20 is made of silicone or rubber. Specifically, the valve disc 20 is integrally molded. By utilizing the elasticity and flexibility of silicone or rubber, the first elastic opening and closing part 21 and the second elastic opening and closing part 22 can be easily pushed open to form a passage area when pushed by the endoscope. After the endoscope is removed, the valve disc 20 can quickly and tightly return to its original shape to achieve self-sealing. By adopting the above structure, a good sealing effect can be achieved, and the manufacturing process is relatively simple, requiring no assembly and saving assembly steps and costs.

[0065] The valve body 10 is provided with an inlet hole 13, a return hole 14, and an outlet hole 15; the inlet hole 13, the return hole 14, and the outlet hole 15 are respectively connected to the valve cavity 11. The solution delivery device 310 is connected to the inlet hole 13; the solution recovery device 320 is connected to the return hole 14; and the observation outlet chamber 124 is connected to the outlet hole 15. In use, physiological saline can flow from the solution delivery device 310 into the valve cavity 11 through the inlet hole 13, and flow to the observation outlet chamber 124 through the outlet hole 15, while excess physiological saline can flow to the solution recovery device 320 through the return hole 14.
