It is designed specifically for microwave ablation surgery guided by magnetic resonance, with the aim of accurately ablating tumors under real-time, high-definition image monitoring.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The magnetic resonance compatible microwave ablation therapy device of this invention utilizes an integrated component for batch sterilization and automatic installation, eliminating the need for manual installation of the ablation needles. Furthermore, all ablation needles to be used are uniformly sterilized after being placed in a sterilization box, achieving integrated sterilization and automatic installation, which helps shorten surgical preparation time and accelerate the surgical process. Moreover, unlike typical batch sterilization where ablation needles are piled up haphazardly, this solution transforms the haphazard stacking of sterilized needles into a linear arrangement. The positioning blocks move according to a preset trajectory, accurately clamping the ablation needles and avoiding clamping failures caused by haphazard stacking and overlapping of needles.

[0021] 2. The magnetic resonance-compatible microwave ablation therapy device of this invention utilizes an embedding and flattening auxiliary component. After the ablation needle body is placed in the sterilization box, multiple deflection blocks can simultaneously reciprocate. As the deflection blocks rotate, friction with the ablation needle body causes it to deflect, thus changing its angle. Simultaneously, in conjunction with the tilt of the sterilization box, the ablation needle can slide more easily into the channel, thereby completing the embedding arrangement more quickly and facilitating subsequent retrieval. If the ablation needle body stands upright and gets stuck at the bottom of the sterilization box, a push rod will push it down, allowing it to pass through the bottom area of ​​the sterilization box in a flat position. This design effectively avoids jamming of the ablation needle body, ensuring the stable operation of the subsequent automatic installation process. Attached Figure Description

[0044] Specifically, in existing technologies, microwave ablation therapy devices are all equipped with microwave ablation needles. These needles need to be disinfected by spraying with disinfectant and irradiating with ultraviolet light before use. Furthermore, after the procedure, the operator needs to disassemble and replace the microwave ablation needle. This frequent manual replacement of the needle is not only cumbersome but also requires repeated disinfection after each replacement, thus prolonging the preparation time and affecting the subsequent surgical progress.

[0045] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0046] Several unused ablation needle bodies 45 are placed into the disinfection tank 3 inside the main body 1. The tank lid 11 is then closed, the ultraviolet lamp 37 is turned on, and the pump 8 is started. The pump 8 draws disinfectant from the storage tank 7, which is then sprayed from multiple nozzles 14 through hoses 9, rigid tube 10, and rigid tube 2 13. The disinfectant sprays onto the surface of the ablation needle bodies 45. Simultaneously, the chain conveyor 5, driven by motor 6 38, rotates rhythmically, causing the ablation needle bodies 45 to slide within the disinfection tank 3. This ensures that the ablation needle bodies 45 are evenly distributed within the disinfection tank 3, guaranteeing uniform irradiation by the ultraviolet lamp 37 and uniform contact with the disinfectant. The used disinfectant falls through the gaps in the chain conveyor 5, passes through the filter 4, and enters the bottom of the main body 1. The used disinfectant can then be drained by opening the valve on the drain pipe 6.

[0047] After all ablation needle bodies 45 have been disinfected, the chain conveyor 5 is started to make the chain plate on the chain conveyor 5 run. Since the spacing between adjacent partitions 16 is equal to the diameter of the fixing block 21 on the ablation needle body 45, multiple partitions 16 form multiple channels on the chain plate with the same diameter as the fixing block 21. Since the length of the ablation needle body 45 is greater than the diameter of the fixing block 21 and the diameter of the ablation needle body 45 is smaller than the diameter of the fixing block 21, the ablation needle body 45 can be embedded in the channel when the side of the fixing block 21 is simultaneously attached to the side of the two partitions 16. When some ablation needles 45 are first added to the sterilization chamber 3, they may already be embedded in different channels. For ablation needles 45 that are not yet embedded in a channel, the sterilization chamber 3 can be driven to swing back and forth through the above operation, causing the ablation needles 45 inside the sterilization chamber 3 to move, thereby changing the posture of the ablation needles 45 in real time. Since the swing amplitude of the sterilization chamber 3 is small, the ablation needles 45 that are already embedded in the channel will remain stable under the limit of the partition 16 until all ablation needles 45 are embedded in the channel. Since the chain plate is in operation, the ablation needles 45 located in the channel will move with the chain plate. When the ablation needles 45 are removed from the inner cavity of the sterilization chamber 3, due to the restriction of the bottom edge of the sterilization chamber 3, overlapping or upright ablation needles 45 will be blocked. Only flat ablation needles 45 can pass through the bottom edge of the sterilization chamber 3, so that the ablation needles 45 passing through the bottom edge of the sterilization chamber 3 are arranged in a linear state and are eventually blocked by the stop bar 15. At this time, the ablation needle body 45 in the sterilization box 3 is in a ready-to-use state. Furthermore, the vision sensor 30 located on the flip block 27 can detect the placement status of the ablation needle body 45 in each channel and upload the status information to the control system.When medical staff need to use the ablation needle body 45, they can hold the handle 2 and pass the threaded fixing rod 43 through the circular through hole on the main body 1, so that one end of the threaded fixing rod 43 is located in the inner cavity of the main body 1. At this time, the system can determine which channel has the ablation needle body 45, and use the motor 23 to drive the threaded rod 22 to rotate, so that the transverse plate 12 moves laterally until the two adjusting rods 34 are simultaneously aligned with the ends of the two partitions 16. Then, the motor 44 drives the stop rod 15 to rotate, so that the stop rod 15 no longer obstructs the ablation needle body 45. Furthermore, when the stop lever 15 moves away from the ablation needle body 45, the chain plate stops operating. Then, the cylinder 24 drives the transverse block 26 to move, causing the two adjusting rods 34 to simultaneously extend into the grooves at the ends of the two partition plates 16 until the positioning block 36 aligns with the fixing block 21 of the ablation needle body 45. Subsequently, the motor 32 drives the bidirectional threaded rod 33 to rotate, causing the two positioning blocks 36 to move closer together and clamp the fixing block 21. At this point, the ablation needle body 45 can be removed from the channel by clamping the fixing block 21 with the positioning block 36. The motor 28 drives the flipping block 27 to rotate 90 degrees. Since the orientation of the ablation needle body 45 being clamped is random, the orientation of the ablation needle body 45 can be determined by the vision sensor 30. Furthermore, the orientation of the ablation needle body 45 can be changed by rotating the positioning block 36 driven by the motor 5 35, so that the needle tip of the ablation needle body 45 faces the slot block 31. At this time, the fixing block 21 and the threaded fixing rod 43 are coaxial, and the fixing block 21 can be sleeved on the threaded fixing rod 43 again by driving the transverse plate 12 to move laterally. Then, motor 329 drives slot block 31 to rotate, thereby achieving threaded connection between fixing block 21 and threaded fixing rod 43 by rotating fixing block 21. Then, positioning block 36 releases fixing block 21. Due to the elasticity of elastic washer 46, the installed ablation needle body 45 can be pulled out from the circular through hole. This achieves automatic installation of the ablation needle body 45. Medical staff can perform surgery by holding handle 2 and using the ablation needle body 45. After the surgery, the used ablation needle body 45 can be removed and discarded. Subsequently, each time the ablation needle body 45 is needed, simply inserting threaded fixing rod 43 into the circular through hole will install the ablation needle body 45, thus eliminating the need for manual installation by operators. Furthermore, all ablation needle bodies 45 to be used will be uniformly sterilized after being placed in sterilization box 3, achieving integrated sterilization and automatic installation, which helps to shorten surgical preparation time and speed up the surgical process. Moreover, under normal circumstances, the ablation needle bodies 45 are in a messy stacked state during batch sterilization. However, this solution can transform the sterilized ablation needle bodies 45 from a messy stacked state to a linear arrangement. The positioning block 36 moves according to the preset trajectory, which can accurately clamp the ablation needle bodies 45 and avoid clamping failure due to the messy stacking and mutual covering of the ablation needle bodies 45.

[0048] In this embodiment, as Figures 5-10 As shown, it also includes embedded and flat-lay auxiliary components;

[0049] The embedded and flat-lay auxiliary components include multiple deflection blocks 19 rotatably mounted on the upper end of the partition 16, and multiple push rods 20 are laterally distributed and slidably connected on one side of the bottom of the disinfection box 3.

[0050] A gear 42 is fixedly connected to one side of the deflection block 19, and multiple racks 41 are slidably connected to one side of the bottom of the disinfection box 3. Each rack 41 extends into the inner cavity of a partition 16. Multiple tooth blocks are intermittently arranged on the rack 41, and each tooth block meshes with a gear 42.

[0051] An electric push rod 39 is fixedly connected to one side of the bottom of the disinfection box 3. A connecting plate 40 is fixedly connected to the piston end of the electric push rod 39. The ends of multiple racks 41 are fixedly connected to the connecting plate 40.

[0052] Multiple push rods 20 are fixedly connected to a connecting plate 17 at their ends. An electric push rod 18 is fixedly connected to one side of the outer wall of the disinfection box 3. The piston end of the electric push rod 18 is fixedly connected to one side of the connecting plate 17.

[0053] Specifically, in the above embodiments, although the ablation needle body 45 can be embedded in the channel and laid flat for subsequent retrieval, when the ablation needle body 45 is not in the correct position, it is difficult to accurately embed the ablation needle body 45 into the channel by simply swinging the sterilization box 3. Furthermore, even if the ablation needle body 45 is embedded in the channel, it may become stuck at the bottom edge of the sterilization box 3 when it moves with the chain plate. This not only affects its smooth passage but also affects the subsequent movement of the ablation needle body 45, thus causing the automatic installation work to be interrupted.

[0054] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows:

[0055] After the ablation needle body 45 is placed in the sterilization box 3, the connecting plate 40 can be moved laterally back and forth by the electric push rod 39. The rack 41 causes multiple gears 42 and deflection blocks 19 to rotate simultaneously. When the deflection blocks 19 rotate, they rub against the ablation needle body 45, causing the ablation needle body 45 to deflect, thus changing its angle. Simultaneously, combined with the tilt of the sterilization box 3, the ablation needle can slide more easily into the channel, thus completing the embedding and arrangement more quickly, facilitating subsequent retrieval. The electric push rod 18 drives the connecting plate 17 to move back and forth horizontally. The push rod 20 pushes the ablation needle body 45 in the channel. Since the push rod 20 is higher than the bottom edge of the disinfection box 3, the ablation needle body 45 will only be pushed by the push rod 20 when it is upright. Under the action of external force, the upright ablation needle body 45 will tilt down until it passes through the bottom of the disinfection box 3 in a flat state. This avoids the ablation needle body 45 getting stuck and ensures the stable operation of the automatic installation of the ablation needle body 45.

[0056] Working Principle: Several unused ablation needle bodies 45 are placed into the disinfection tank 3 inside the main body 1. The tank lid 11 is then closed, the ultraviolet lamp 37 is turned on, and the pump 8 is started. The pump 8 draws disinfectant from the storage tank 7, which is then sprayed from multiple nozzles 14 through hoses 9, rigid tube 10, and rigid tube 2 13. The disinfectant sprays onto the surface of the ablation needle bodies 45. Simultaneously, the chain conveyor 5, driven by motor 6 38, rotates regularly, causing the ablation needle bodies 45 to slide within the disinfection tank 3. This ensures that the ablation needle bodies 45 are evenly distributed within the disinfection tank 3, guaranteeing uniform irradiation by the ultraviolet lamp 37 and uniform contact with the disinfectant. The used disinfectant falls through the gaps in the chain conveyor 5, passes through the filter 4, and enters the bottom of the main body 1. The used disinfectant can then be drained by opening the valve on the drain pipe 6.

[0057] After all ablation needle bodies 45 have been disinfected, the chain conveyor 5 is started to make the chain plate on the chain conveyor 5 run. Since the spacing between adjacent partitions 16 is equal to the diameter of the fixing block 21 on the ablation needle body 45, multiple partitions 16 form multiple channels on the chain plate with the same diameter as the fixing block 21. Since the length of the ablation needle body 45 is greater than the diameter of the fixing block 21 and the diameter of the ablation needle body 45 is smaller than the diameter of the fixing block 21, the ablation needle body 45 can be embedded in the channel when the side of the fixing block 21 is simultaneously attached to the side of the two partitions 16. When some ablation needles 45 are first added to the sterilization chamber 3, they may already be embedded in different channels. For ablation needles 45 that are not yet embedded in a channel, the sterilization chamber 3 can be driven to swing back and forth through the above operation, causing the ablation needles 45 inside the sterilization chamber 3 to move, thereby changing the posture of the ablation needles 45 in real time. Since the swing amplitude of the sterilization chamber 3 is small, the ablation needles 45 that are already embedded in the channel will remain stable under the limit of the partition 16 until all ablation needles 45 are embedded in the channel. Since the chain plate is in operation, the ablation needles 45 located in the channel will move with the chain plate. When the ablation needles 45 are removed from the inner cavity of the sterilization chamber 3, due to the restriction of the bottom edge of the sterilization chamber 3, overlapping or upright ablation needles 45 will be blocked. Only flat ablation needles 45 can pass through the bottom edge of the sterilization chamber 3, so that the ablation needles 45 passing through the bottom edge of the sterilization chamber 3 are arranged in a linear state and are eventually blocked by the stop bar 15. At this time, the ablation needle body 45 in the sterilization box 3 is in a ready-to-use state. Furthermore, the vision sensor 30 located on the flip block 27 can detect the placement status of the ablation needle body 45 in each channel and upload the status information to the control system.When medical staff need to use the ablation needle body 45, they can hold the handle 2 and pass the threaded fixing rod 43 through the circular through hole on the main body 1, so that one end of the threaded fixing rod 43 is located in the inner cavity of the main body 1. At this time, the system can determine which channel has the ablation needle body 45, and use the motor 23 to drive the threaded rod 22 to rotate, so that the transverse plate 12 moves laterally until the two adjusting rods 34 are simultaneously aligned with the ends of the two partitions 16. Then, the motor 44 drives the stop rod 15 to rotate, so that the stop rod 15 no longer obstructs the ablation needle body 45. Furthermore, when the stop lever 15 moves away from the ablation needle body 45, the chain plate stops operating. Then, the cylinder 24 drives the transverse block 26 to move, causing the two adjusting rods 34 to simultaneously extend into the grooves at the ends of the two partition plates 16 until the positioning block 36 aligns with the fixing block 21 of the ablation needle body 45. Subsequently, the motor 32 drives the bidirectional threaded rod 33 to rotate, causing the two positioning blocks 36 to move closer together and clamp the fixing block 21. At this point, the ablation needle body 45 can be removed from the channel by clamping the fixing block 21 with the positioning block 36. The motor 28 drives the flipping block 27 to rotate 90 degrees. Since the orientation of the ablation needle body 45 being clamped is random, the orientation of the ablation needle body 45 can be determined by the vision sensor 30. Furthermore, the orientation of the ablation needle body 45 can be changed by rotating the positioning block 36 driven by the motor 5 35, so that the needle tip of the ablation needle body 45 faces the slot block 31. At this time, the fixing block 21 and the threaded fixing rod 43 are coaxial, and the fixing block 21 can be sleeved on the threaded fixing rod 43 again by driving the transverse plate 12 to move laterally. Then, motor 329 drives slot block 31 to rotate, thereby achieving threaded connection between fixing block 21 and threaded fixing rod 43 by rotating fixing block 21. Then, positioning block 36 releases fixing block 21. Due to the elasticity of elastic washer 46, the installed ablation needle body 45 can be pulled out from the circular through hole. This achieves automatic installation of the ablation needle body 45. Medical staff can perform surgery by holding handle 2 and using the ablation needle body 45. After the surgery, the used ablation needle body 45 can be removed and discarded. Subsequently, each time the ablation needle body 45 is needed, simply inserting threaded fixing rod 43 into the circular through hole will install the ablation needle body 45, thus eliminating the need for manual installation by operators. Furthermore, all ablation needle bodies 45 to be used will be uniformly sterilized after being placed in sterilization box 3, achieving integrated sterilization and automatic installation, which helps to shorten surgical preparation time and speed up the surgical process. Moreover, under normal circumstances, the ablation needle bodies 45 are in a messy stacked state during batch sterilization. However, this solution can transform the sterilized ablation needle bodies 45 from a messy stacked state to a linear arrangement. The positioning block 36 moves according to the preset trajectory, which can accurately clamp the ablation needle bodies 45 and avoid clamping failure due to the messy stacking and mutual covering of the ablation needle bodies 45.After the ablation needle body 45 is placed in the sterilization box 3, the connecting plate 40 can be moved laterally back and forth by the electric push rod 39. The rack 41 causes multiple gears 42 and deflection blocks 19 to rotate simultaneously. When the deflection blocks 19 rotate, they rub against the ablation needle body 45, causing the ablation needle body 45 to deflect, thus changing its angle. Simultaneously, combined with the tilt of the sterilization box 3, the ablation needle can slide more easily into the channel, thus completing the embedding and arrangement more quickly, facilitating subsequent retrieval. The electric push rod 18 drives the connecting plate 17 to move back and forth horizontally. The push rod 20 pushes the ablation needle body 45 in the channel. Since the push rod 20 is higher than the bottom edge of the disinfection box 3, the ablation needle body 45 will only be pushed by the push rod 20 when it is upright. Under the action of external force, the upright ablation needle body 45 will tilt down until it passes through the bottom of the disinfection box 3 in a flat state. This avoids the ablation needle body 45 getting stuck and ensures the stable operation of the automatic installation of the ablation needle body 45.
