Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of medical devices, and in particular to a multi-way valve assembly. Background Art
[0002] Vascular interventional surgery is an operation technique that uses puncture needles, guide wires, catheters and other interventional consumables to diagnose and treat through blood vessels under the guidance of medical imaging equipment. However, vascular interventional surgery needs to be performed under ionizing radiation. To ensure the safety of personnel, doctors need to wear heavy lead suits for safety protection, which may cause damage to the doctor's skeletal system in the long run. With the rapid development of intelligent technology and medicine, the development of vascular interventional surgery robots has become a reality.
[0003] In the relevant operating equipment, doctors usually use a Y-valve to control the fixation or movement of the interventional consumables, so that doctors can adjust the different movement states of the interventional consumables through the Y-valve, thereby performing different surgical operations on the patient. Specifically, the Y-valve includes a valve body, a locking member, an exhaust valve, a catheter connector and an injection connector. The valve body has four ports that are interconnected. One end of the catheter connector is connected to one of the ports of the valve body, and the other end is connected to the catheter. During the vascular interventional surgery, the catheter connector is rotated to achieve control of the rotational movement of the catheter. At the same time, different operations of the surgical process are achieved by injecting different types of liquids into the injection connector.
[0004] However, before the doctor operates the Y-valve to control the movement of the catheter, the insertion end of the valve body and the catheter connector, as well as the transmission gear that provides power to the catheter connector, need to be assembled first. At the same time, a transmission gear that matches the catheter connector needs to be prepared in advance, which complicates the doctor's operation and is not conducive to the doctor's operation.

[0054] The present disclosure provides a multi-way valve assembly, which includes a valve body and a driver. The driver includes a fixed part, a driving part and a power part. The fixed part is fixedly arranged at the adjustment end, the driving part includes a rotating part and a connecting part, the connecting part includes a connecting unit and a first gear, one side of the rotating part is rotatably connected to the fixed part, and the other side is connected to the connecting unit, the other side of the connecting unit is connected to the second interventional consumable, the connecting unit is passed through the axis of the first gear, the power part includes a motor and a second gear, the second gear is connected to the output shaft of the motor, meshed with the first gear, and is used to drive the connecting part to drive the second interventional consumable to rotate under the drive of the motor, wherein the connecting part is an integrally formed structure. The multi-way valve assembly disclosed in the present disclosure can reduce the preparation process before vascular intervention surgery and simplify the doctor's operation.
[0055] The present disclosure provides a multi-way valve assembly 1. Figure 1 and Figure 2 As shown, the multi-way valve assembly 1 includes a valve body 2 and a driver 3. The valve body 2 serves as the core body of the multi-way valve assembly 1, and the driver 3 serves as the driving unit of the multi-way valve assembly 1. It is arranged at one end of the multi-way valve assembly 1 and is connected to the second interventional consumable to drive the rotational movement of the second interventional consumable. It should be noted that the multi-way valve 1 disclosed in the present invention can be used in both traditional manual interventional surgery and interventional surgery performed with the aid of a vascular interventional surgical robot. This change in application scenario does not affect the protection scope of the present disclosure.
[0056] The valve body 2 includes a liquid inlet end 21, an adjustment end 22 and an insertion end 23 extending outward from the center of the valve body 2 to form the valve body 2. The insertion end is used for inserting the first interventional consumable, and the adjustment end is used to connect with the second interventional consumable. The first interventional consumable can be inserted into the second interventional consumable. The interventional consumable is inserted into the valve body 2 through the insertion end 23. The insertion end 23 is used to lock or unlock the interventional consumable, so that the interventional consumable is fixed or moved relative to the valve body 2. It can be understood that the above-mentioned locking is to clamp the first interventional consumable and not allow it to move, and unlocking is to keep a certain gap with the first interventional consumable and allow it to move. The liquid inlet end 21 is connected to the pipeline to inject the external liquid into the valve body 2. By injecting different types of liquids, different use requirements of the interventional consumable to intervene in the patient's treatment site are realized; the adjustment end 22 is provided with a driver 3, which is connected to the second interventional consumable and is used to rotate the second interventional consumable, thereby rotating the second interventional consumable so that the second interventional consumable can accurately intervene in the patient's treatment site.
[0057] It should be noted that interventional consumables are medical devices such as catheters, guidewires, and stents, among which the first interventional consumable is usually a guidewire, and the second interventional consumable is usually a catheter.
[0058] Furthermore, the driver 3 is connected to the regulating end 22. Figure 3 and Figure 4As shown, the driver 3 includes a fixing portion 31, a driving portion 32 and a power portion 33. The fixing portion 31 is fixed to the adjustment end 22, and is used to fix and support the driving portion 32, so that the driving portion 32 can operate normally. The driving portion 32 is rotatably connected to the fixing portion 31, and the driving portion 32 includes a rotating member 321 and a connecting member 322. The connecting member 322 includes a connecting unit 3221 and a first gear 3222. One side of the rotating member 321 is rotatably connected to the fixing portion 31, and the other side is connected to the connecting unit 3221. The other side of the connecting unit 3221 is connected to the second interventional consumable. The connecting unit 3221 is penetrated at the axis of the first gear 3222, so that the second interventional consumable is driven to rotate during the rotation of the driving portion 32 relative to the fixing portion 31 to meet different operation requirements. The power unit 33 includes a motor 331 and a second gear 332. The second gear 332 is connected to the output shaft of the motor 331 and meshes with the first gear 3222, and is used to drive the connecting member 322 to drive the second interventional consumable to rotate under the drive of the motor 331. The connecting member 322 is an integrated structure.
[0059] Specifically, the output shaft of the motor 331 drives the second gear 332 to rotate. Under the meshing action of the first gear 3222 and the second gear 332, the second gear 332 drives the first gear 3222 to rotate. Since the connecting unit 3221 is arranged at the axis center of the first gear 3222, the connecting unit 3221 is connected between the rotating member 321 and the second interventional consumable. The other side of the rotating member 321 is rotatably connected to the fixed part 31, so that the first gear 3222 drives the connecting unit 3221 to rotate relative to the fixed part 31, and then drives the second interventional consumable to rotate relative to the fixed part 31, so as to realize the rotation of the second interventional consumable in the blood vessel.
[0060] Since the connecting piece 322 is an integrally formed structure, when the doctor controls the second interventional consumable through the multi-way valve assembly 1 to perform a vascular interventional surgery, the doctor only needs to directly connect the connecting piece 322 to the second interventional consumable to control the movement of the second interventional consumable through the multi-way valve assembly 1. Before the vascular interventional surgery, the doctor does not need to pre-install structures such as the connecting unit 3221 and the first gear 3222 in the connecting piece 322. At the same time, there is no need to match the connecting unit 3221 connected to the second interventional consumable with a matching gear, which can reduce the preparation process before the vascular interventional surgery and simplify the doctor's operation.
[0061] In addition, since the connecting member 322 is an integrally formed structure, the connecting unit 3221 and the first gear 3222 in the connecting member 322 are integrally formed structures. It can be understood that the connecting unit 3221 and the first gear 3222 in the connecting member 322 are integrally formed during design and production, and the connecting unit 3221 and the first gear 3222 in the connecting member 322 are actually an integral structure. Compared with the integrally formed connection, although the two structures are connected into an integral structure through the integrally formed connection, the structure connected by the integrally formed connection is actually still two separate structures, and the two structures still have the disadvantages of the connection structure, such as the connection part is easy to crack, the overall structural stability is low and other defects. Since the connecting member 322 is an integrally formed structure, there is no connection relationship between the connecting unit 3221 and the first gear 3222 in the connecting member 322. The connecting member 322 is a unified whole. The connecting unit 3221 and the first gear 3222 of the connecting member 322 are not prone to cracking. The connecting member 322 has better stability, which can enable the connecting member 322 to operate stably, thereby improving the overall reliability of the multi-way valve assembly 1.
[0062] At the same time, since the transmission movement is realized between the driving part 32 and the power part 33 through the meshing of the first gear 3222 and the second gear 332, on the one hand, the gear transmission has high precision, and the dynamic load can be reduced under high-speed movement, so as to realize the smooth transmission of the first gear 3222 and the second gear 332. On the other hand, the gear transmission has high efficiency, and in the process of the second gear 332 driving the first gear 3222 to transmit, the power loss in the transmission process can be reduced, thereby improving the transmission efficiency of the second gear 332 to the first gear 3222 in the transmission process.
[0063] It should be noted that although the worm gear transmission method can also achieve the function of power transmission, and the worm gear transmission method can also achieve the effect of smooth transmission and compact structure during the transmission process, the worm gear transmission efficiency is low and it is not easy to work at high power for a long time. At the same time, the production cost of the worm gear is high. Since the present invention adopts the meshing movement of the first gear 3222 and the second gear 332 to realize power transmission, it can have a higher transmission efficiency during the transmission process and can work at high power for a long time. At the same time, it can reduce the production cost of the first gear 3222 and the second gear 332, thereby reducing the overall manufacturing cost of the multi-way valve assembly 1.
[0064] The various parts of the multi-way valve assembly 1 are described in detail below:
[0065] In an exemplary embodiment of the present disclosure, a first groove 3223 is provided at one end of the connecting unit 3221 facing the rotating member 321, and a first protrusion 3211 is provided at one end of the rotating member 321 facing the connecting unit 3221. The first protrusion 3211 is fixedly connected to the first groove 3223, and the shapes of the first protrusion 3211 and the first groove 3223 match. Figure 4 , Figure 5 and Figure 6 As shown, since a first groove 3223 is provided at one end of the connecting unit 3221 facing the rotating member 321, a first protrusion 3211 is provided at one end of the rotating member 321 facing the connecting unit 3221, the first protrusion 3211 is fixedly connected to the first groove 3223, and the shapes of the first protrusion 3211 and the first groove 3223 match each other, in the process of connecting the rotating member 321 and the connecting unit 3221, the connection between the rotating member 321 and the connecting unit 3221 can be made tighter through the cooperation of the first protrusion 3211 and the first groove 3223, thereby avoiding the rotating member 321 and the connecting unit 3221 from falling off, thereby improving the overall stability of the driving unit 32.
[0066] In an exemplary embodiment of the present disclosure, the first protrusion 3211 is connected to the first groove 3223 by ultrasonic welding. Figure 4 and Figure 6 As shown, ultrasonic welding uses high-frequency ultrasonic energy (15-50khz) to generate low-amplitude (1-100μm) mechanical vibrations, which are transmitted to the component connection joints to generate heat, causing the thermoplastic material to melt and form a weld after cooling. Ultrasonic welding is the fastest welding technology known to date, and the welding time is usually between 0.1 seconds and 1.0 seconds. Since the first protrusion 3211 is connected to the first groove 3223 by ultrasonic welding, on the one hand, ultrasonic welding uses high-frequency ultrasonic vibration welding, which can quickly weld the first protrusion 3211 and the first groove 3223, thereby improving the efficiency of welding the first protrusion 3211 and the first groove 3223. On the other hand, ultrasonic welding reduces the operational hazards during the welding process of the first protrusion 3211 and the first groove 3223 due to indirect heating, and can improve the safety during the operation. In addition, the first protrusion 3211 and the first groove 3223 after welding can be connected more closely, thereby improving the overall stability of the drive unit 32.
[0067] In an exemplary embodiment of the present disclosure, Figure 1 , Figure 3 and Figure 5As shown, the fixed portion 31 includes a blocking member 311 and a matching member 312. The blocking member 311 is arranged at a side away from the connecting member 322, connected to the adjusting end 22 of the valve body 2, and used to prevent the rotating member 321 from moving along the adjusting end 22 of the valve body 2 toward the insertion end 23 of the valve body 2. The matching member 312 is fixedly connected to the blocking member 311 and rotatably connected to the rotating member 321.
[0068] Specifically, since the fixed part 31 includes a blocking member 311 and a matching member 312, the blocking member 311 is arranged on a side away from the connecting member 322. When the connecting member 322 is driven by the motor 331, the blocking member 311 can provide a blocking force for the connecting member 322 along the insertion end 23 of the valve body 2 toward the adjustment end 22 of the valve body 2 under the driving action of the motor 331, so that the connecting member 322 can only rotate along the movement of the motor 331 to avoid the connecting member 322 from moving in other directions and causing abnormal operation of the driving part 32, affecting the normal operation. In addition, since the matching member 312 is fixedly connected to the blocking member 311 and rotatably connected to the rotating member 321, it can serve as a transition structure between the blocking member 311 and the rotating member 321, which can protect the rotating member 321 from causing wear or even damage to the blocking member 311 during the movement, thereby improving the overall service life of the driving part 32.
[0069] In an exemplary embodiment of the present disclosure, Figure 2 , Figure 5 and Figure 6As shown, the matching member 312 includes a limiting unit 3121 and a movable unit 3122. Among them, one end of the limiting unit 3121 is fixedly connected to the blocking member 311, and the rotating member 321 is rotatably connected to the limiting unit 3121. The movable unit 3122 is fixedly connected to one end of the limiting unit 3121 away from the blocking member 311, and the connecting unit 3221 is rotatably connected to the movable unit 3122. Specifically, since one end of the limiting unit 3121 is fixedly connected to the blocking member 311, and the rotating member 321 is rotatably connected to the limiting unit 3121, when the motor 331 drives the connecting member 322 to rotate and drives the rotating member 321 to rotate relative to the blocking member 311, the limiting effect of the limiting unit 3121 can be used to limit the rotating member 321 in directions other than the rotation direction, so as to prevent the rotating member 321 from deviating from the rotation direction and affecting the normal operation of the driver 3. At the same time, the movable unit 3122 is fixedly connected to one end of the limiting unit 3121 away from the blocking member 311, and the connecting unit 3221 is rotatably connected to the movable unit 3122, which can prevent the connecting unit 3221 from being unable to rotate normally relative to the matching member 312 during the rotation process, thereby causing the connecting unit 3221 to be unable to rotate and the rotating member 321 to rotate mismatched. The driving part 32 can operate normally relative to the fixed part 31 under the power drive of the power part 33.
[0070] In an exemplary embodiment of the present disclosure, a second protrusion 3123 is provided on the circumferential outer wall of the limiting unit 3121. Figure 5 and Figure 6 As shown, the rotating member 321 includes a body 3212 and a notch 3213, the body 3212 is arranged between the blocking member 311 and the second protrusion 3123, and the second protrusion 3123 is clamped in the notch 3213. Specifically, since the second protrusion 3123 is arranged on the circumferential outer wall of the limiting unit 3121, the body 3212 of the rotating member 321 is arranged between the blocking member 311 and the second protrusion 3123, and the second protrusion 3123 is clamped in the notch 3213. Based on this arrangement, on the one hand, the limiting effect of the limiting unit 3121 on the rotating member 321 can be ensured by the clamping connection between the limiting unit 3121 and the rotating member 321, and on the other hand, in the process of the limiting unit 3121 clamping the rotating member 321, the rotating member 321 can be rotated relative to the limiting unit 3121, so that the rotating member 321 only rotates relative to the limiting unit 3121 without other movements, thereby improving the reliability of the driving part 32.
[0071] In an exemplary embodiment of the present disclosure, Figure 1 , Figure 3 and Figure 6As shown, the driver 3 also includes a sealing portion 34. The sealing portion 34 includes a sealing ring 341; a second groove 3124 is provided on the circumferential outer wall of the movable unit 3122, and the sealing ring 341 is embedded in the second groove 3124 and connected to the inner wall of the connecting unit 3221. Specifically, in the process of controlling the rotation of the second interventional consumable by the driver 3, the doctor needs to inject liquid into the liquid inlet end 21 to achieve different operations on the patient's treatment site. In the process of injecting liquid, the liquid will pass through the valve body 2 and then through the second interventional consumable into the patient's blood vessel. Since the second groove 3124 is provided on the circumferential outer wall of the movable unit 3122, and the sealing ring 341 is embedded in the second groove 3124, it can be prevented that the liquid leaks out of the valve body 2 from the gap between the inner wall of the movable unit 3122 and the connecting unit 3221 through the second groove 3124, so that the vascular intervention surgery can be carried out normally.
[0072] In an exemplary embodiment of the present disclosure, Figure 3 and Figure 6 As shown, the inner wall of the connection unit 3221 is provided with a third protrusion, and the sealing portion 34 further includes a sealing pad 342. The sealing pad 342 is provided in the inner wall of the connection unit 3221, and along the axial direction of the connection unit 3221, the sealing pad 342 abuts between the third protrusion and the end surface of the movable unit 3122 away from the limiting unit 3121. Similarly, since there is a gap between the connection unit 3221 and the movable unit 3122, the sealing pad 342 abuts between the third protrusion and the end surface of the movable unit 3122 away from the limiting unit 3121, and during the process of injecting liquid at the liquid inlet end 21, the liquid can be prevented from leaking out of the valve body 2 through the gap between the connection unit 3221 and the movable unit 3122, so that the normal progress of the vascular intervention surgery can be ensured.
[0073] In an exemplary embodiment of the present disclosure, both the blocking member 311 and the rotating member 321 are annular, and the cross section of the regulating end 22 of the valve body 2 is annular. The diameter of the rotating member 321 is smaller than the diameter of the blocking member 311, and larger than the diameter of the regulating end 22 of the valve body 2. Specifically, since the diameter of the rotating member 321 is smaller than the diameter of the blocking member 311, and larger than the diameter of the regulating end 22 of the valve body 2, on the one hand, it can ensure that the rotating member 321 is firmly connected to the regulating end 22, and at the same time, when the insertion end 23 needs to insert a guide wire with a smaller diameter, it is possible to insert the guide wire with a smaller diameter into the insertion end 23 and penetrate the regulating end 22. On the other hand, when the rotating member 321 is affected by other interference factors such as external forces, the rotating member 321 will be prevented from further moving toward the direction of the blocking member 311 under the effect of the size of the blocking member 311 itself, thereby reducing the possibility of failure of the driver 3 and improving the reliability of the driver 3.
[0074] In an exemplary embodiment of the present disclosure, the connection unit 3221 is a Luer connector. Specifically, the Luer connector is a standardized micro-seepage-free connector, which is connected by a male Luer connector and a matching female Luer connector. Since the connection unit 3221 is a Luer connector, the connection between the connection member 322 and the rotating member 321 can be made more secure, thereby making the driver 3 more stable as a whole. At the same time, the Luer connector is easy to assemble, which can facilitate the assembly process between the connection unit 3221 and the rotating member 321 and simplify the doctor's operation.
[0075] In an exemplary embodiment of the present disclosure, the valve body 2 further includes an exhaust end 24 extending outward from the center of the valve body 2, which is used to control the exhaust or sealing of the valve body 2. Specifically, the exhaust end 24 serves as the exhaust portion of the valve body 2. Since the doctor injects liquid into the valve body 2 through the liquid inlet end 21, there will be gas inside the valve body 2. The gas needs to be discharged from the valve body 2 through the exhaust end 24 to prevent the gas from entering the patient's blood vessels through the valve body 2, thereby causing safety hazards.
