Description

Technical Field

[0001] The invention belongs to the technical field of signal transmission, and in particular relates to a microwave RDN ablation device. Background Art

[0002] Microwave ablators: usually composed of microwave generators, control systems, cooling systems and ablation needles. Microwave generators generate microwave energy of a specific frequency, which is then transmitted to ablation needles through transmission cables. When the ablation needle is inserted into the diseased tissue (e.g., tumor), the microwave energy causes the polar molecules in the tissue to rotate at high speed, generating frictional heat, causing the diseased tissue to rapidly heat up to 60°C-100°C in a short period of time until protein denaturation or cell coagulative necrosis occurs.

[0003] During specific operation, vibration transmission of peripheral equipment, vibration of building structures (for example, vibration generated during vehicle driving and vibration of nearby construction transmitted to the working area of ​​the microwave ablation device through the building structure), movement of people or carrying of objects, etc., will all affect the normal operation of the microwave ablation device; that is, the aforementioned vibrations may cause the position between the cathode and anode inside the microwave generator to loosen or shift. However, the distance between the cathode and the anode is a key factor affecting the emission of the electron beam and the generation of microwaves. Once the distance changes due to vibration or impact, the movement trajectory of the electron beam and the interaction with the high-frequency electromagnetic field will be disturbed, thereby affecting the generation and output stability of microwaves.

[0004] Under the action of continuous vibration and impact, relative friction and collision are constantly generated between the internal components of the microwave generator. However, the rotating anode in the microwave generator rotates at high speed during normal operation, and the vibration will increase the friction between the anode and the supporting structure. Over time, the anode surface will be damaged, which will affect the rotation accuracy and heat dissipation performance, reduce the service life of the microwave generator, and even cause deformation or damage to the cathode structure, resulting in reduced or uneven electron emission, affecting the electron emission capacity and emission angle, and interfering with the microwave generation efficiency and frequency stability;

[0005] At the same time, the microwave generator will generate a lot of heat during operation, and the heat needs to be dissipated through the heat dissipation structure to ensure its normal operating temperature. However, the heat sink may be deformed or broken due to vibration, reducing the contact area with the air and reducing the heat dissipation efficiency. In addition, external vibration or impact, on the one hand, causes irregular flow of air around the microwave ablator, resulting in a negative pressure effect, increasing the probability of contact between dust and impurities originally suspended in the air and at a certain distance from the heat dissipation port and the heat dissipation port, further reducing the heat dissipation effect of the heat dissipation port. On the other hand, vibration and impact cause collision and friction between the microwave ablator and air molecules. In this process, dust is broken into smaller particles, which not only increases the amount and adhesion of dust, but also causes dust to carry static electricity, increasing the probability of dust adhesion to the heat dissipation port, and ultimately causing the heat dissipation system to be unable to effectively remove heat, causing the temperature of the microwave generator to rise, affecting its performance and life.

[0006] In addition, external vibration or impact will not only increase additional heat energy, but also change the inductance and capacitance parameters of electronic components, thereby increasing the corresponding energy loss and affecting the instantaneous increase in the internal ambient temperature of the microwave ablation device until it exceeds the heat dissipation load of the heat dissipation system per unit time, affecting the normal working efficiency and stability of the microwave generator.

[0032] The stand, the number of which is one, is mounted on one end of the vertical plate close to the trachea by sliding and snap-fitting;

[0040] The instantaneous temperature control method of the internal environment of the microwave generator adopts the above-mentioned microwave RDN ablation device to provide temperature adjustment, and the specific steps are as follows:

[0041] S1: First, the column collides with the spring rod, and then the outer rack meshes with the sun gear under the control of the spring rod. During the meshing process between the planetary gear and the sun gear, the inner rack synchronously drives the wall plate to move away from the double ear plate until the wedge plate and the gear ring move relative to each other.

[0042] S2: Then the gear ring is controlled to move with the shift plate through the gear ring, and then the ring sleeve is squeezed by the shift plate to drive the band plate to move away from the right-angle plate, until the ball rod continuously moves with the snake mouth groove of the outer wall of the convex coupling column under the control of the support;

[0043] S3: Finally, the pulley transmission effect causes the convex coupling column on the side close to the seat to rotate synchronously. In this process, the air column drives the seat under the guidance of the vertical plate through the snake-mouth groove, pulling the air plug away from the right-angle plate until the air column is engaged with the straight groove. After that, the air plug moves toward the air pipe under the restoring action of the telescopic spring, and finally blows the gas in the air pipe evenly to each component through the spray valve.

[0044] The present invention has the following beneficial effects:

[0045] 1. The present invention controls the strip plate to synchronously drive the support to move to the specified position through the mutual meshing action between the gear ring and the band plate. During this process, the ball rod continuously moves relative to the snake mouth groove. Thereafter, the convex coupling column synchronously rotates a specified angle or number of circles under the action of the pulley transmission until the positive electrode plate contacts the negative electrode plate. Finally, the air column is separated from the engagement state with the snake mouth groove and is engaged with the straight groove. Subsequently, the air plug is instantly moved inside the air pipe under the reset action of the telescopic spring, thereby increasing the air pressure in the air pipe and spraying cold air into the chassis through the spray valve, providing an additional cooling solution, increasing the heat dissipation area and the flow rate of the cooling medium, thereby more effectively reducing the instantaneous temperature rise of the internal environment of the microwave ablation device, improving the reliability of the cooling system, and enhancing the tolerance of equipment failures.

[0046] 2. The present invention strengthens the meshing degree between the sun gear and the outer rack through the planetary gear. After that, the impact degree between the column and the spring rod is further reflected by the single movement distance of the inner rack, while reducing the energy loss of weak impact between the column and the spring rod, that is, strengthening the impact frequency range between the column and the spring column, avoiding energy loss in the state where low-frequency impact is not expressed or cannot be expressed, which helps to improve the energy conversion efficiency of the energy storage unit and fully ensure the stability of the working environment temperature inside the chassis.

[0047] 3. The present invention limits the steering range of the shift plate through the specific spatial distribution between the clamping plate and the ring sleeve, so that when the wedge plate and the gear ring are separated from each other, the gear ring synchronously limits the rotation of the gear ring under the limiting action of the shift plate, that is, for multiple mutual movements between the wedge plate and the gear ring (without a smooth curved surface), the gear ring always rotates unidirectionally at a specified angle until the positive electrode plate contacts the negative electrode plate, and the collision energy between the column and the spring column each time is stored in the telescopic spring, realizing energy transfer and utilization, improving the energy utilization efficiency of the system, enhancing the fault tolerance and reliability of the system, and reducing energy waste.

[0086] The filtering (or absorption) process of the balancing unit 2 for low amplitude vibration or shock:

[0087] When chassis 1 is subjected to external vibration (low frequency) and impact:

[0088] The energy generated by external vibration or impact is continuously transmitted to the coil spring 24 through the work surface column 22. Thereafter, the coil spring 24 itself deforms elastically, converting the aforementioned impact kinetic energy (part) into its own elastic potential energy, reducing the undulation depth of the decorative panel 23, filtering low-frequency vibrations, and reducing physical damage (conventional components usually adopt a direct fixed installation method, and external vibrations or impacts are directly transmitted to the components, causing the components to be prone to physical damage such as cracks, deformations, or even fractures. Therefore, the coil spring 24 can effectively absorb and buffer external low-frequency vibrations and impacts, reduce the risk of component damage, and at the same time effectively reduce the stress amplitude and stress cycle number of the components, delay fatigue damage, and increase their service life);

[0089] When chassis 1 is subjected to overclocking vibration (overclocking here is relative, and the determination of the specific vibration frequency can be provided by external experimental data):

[0090] At this time, the coil spring 24 can only absorb part of the impact (or vibration) kinetic energy, and the column 26 is under the control of the decorative panel 23 (the coil spring 24 continuously drives the decorative column to perform nonlinear reciprocating motion under the support and guidance of the working surface column 22 during the deformation process), and continuously collides with the spring rod 33;

[0091] Take the single collision process of the column 26 and the spring rod 33 as an example:

[0092] When the spring rod 33 is hit by the column 26 (the guard 25 further improves the movement stability of the column 26, reduces the probability of radial runout, reduces friction, and reduces the form of heat energy generation), the spring rod 33 is guided by the double ear plate 32 to stably control the outer rack 34 to mesh with the sun gear 36;

[0093] Thereafter, during the meshing process between the planetary gear 37 and the sun gear 36 (in specific implementation, the diameter of the sun gear 36 is larger than that of the planetary gear 37, so as to enhance the expression of the rotation angle of the sun gear 36 by the planetary gear 37, that is, when the sun gear 36 rotates five degrees, the planetary gear 37 rotates at least ten degrees, accurately and precisely reflecting the degree of collision between the column 26 and the spring rod 33; in addition, the additional sun gear 36 can effectively coordinate the movement direction of the outer rack 34 and the inner rack 38, which is conducive to reasonable layout and enhances the feasibility of the scheme), the inner rack 38 synchronously drives the wall plate 361 to move away from the double ear plate 32 (the wall plate 361 is guided by the right-angle plate 31 and stably moves in the horizontal section direction of the right-angle plate 31), until the wedge plate 363 is engaged with the gear ring 375 (the full-tooth gear ring 375, that is, the gear ring 375 without a smooth curved surface on the outer wall);

[0094] The single energy storage process of the energy storage unit 3 when the column 26 hits the spring rod 33:

[0095] When the wall plate 361 is moving, the wedge plate 363 (the purpose of more than one set of wedge plates 363 is to meet the expression of different amplitudes of collision between the column 26 and the spring rod 33, that is, a single wedge plate 363 drives the ring gear 375 to rotate a limited number of times, and multiple wedge plates 363 can realize continuous rotation of the ring gear 375 to rotate any angle or number of times. In addition, the aforementioned expression form of strengthening the sun gear 36 by the planetary gear 37 can effectively transmit the degree of meshing between the wedge plate 363 and the ring gear 375 here) changes from a state of not contacting the ring gear 375 to a state of mutual engagement, and the ring gear 375 is forced to rotate a certain angle (the rotation angle of the ring gear 375 is determined by the degree of collision between the column 26 and the spring rod 33) through the wedge plate 363;

[0096] The state transition process of the wedge plate 363 during the reciprocating motion is as follows:

[0097] When the wedge plate 363 moves toward the gear ring 375 and engages with the gear ring 375, the wedge plate 363 has a tendency to rotate away from the wall plate 361 under the reverse action of the gear ring 375. At this time, in order to ensure that the wedge plate 363 drives the gear ring 375 to rotate, the shaft wheel 366 is used to limit the wedge plate 363 (the folding plate 365 provides stable support to the shaft wheel 366).

[0098] On the contrary, when the wedge plate 363 moves to the initial position under the control of the inner rack 38 (the outer rack 34, under the reset action of the spring rod 33, prompts the sun gear 36 and the planetary gear 37 to make a reverse movement different from the aforementioned movement), the wedge plate 363 is in contact with the ring gear 375. Under the squeezing action of the ring gear 375, it rotates toward the wall plate 361 until the wedge plate 363 is completely separated from the ring gear 375 (and when the wedge plate 363 is no longer in contact with the ring gear 375, the wedge plate 363 returns to the initial position under the action of the return spring 364, and a certain interaction force is maintained between the coaxial wheels 366);

[0099] The process of realizing the continuous unidirectional rotation of the gear ring 375 (the gear ring 375 rotates continuously in only one direction and does not reverse):

[0100] The gear ring 375 (the full gear ring 375 is only engaged with the wedge plate 363 through the full gear ring 375) rotates a certain angle under the extrusion of the wedge plate 363. During this process, the gear ring 376 (connected to the full gear ring 375) contacts the paddle 372, forcing the paddle 372 to drive the ring sleeve 369 to rotate (at this time, the rotation direction of the ring sleeve 369 is set to reverse, that is, when the gear ring 376 rotates reversely, the clamping plate 373 limits the rotation direction of the paddle 372, and the paddle 372 cannot be turned over at this time. When the gear ring 376 rotates forward, the paddle 372 is forced to turn over a certain angle, and the limit of the paddle 372 on the gear ring 376 is released. For details, please refer to the ratchet pawl);

[0101] For partial toothed ring gear 375:

[0102] At this time, the incomplete gear ring 375, under the control of the ring sleeve 369, synchronously drives the gear ring 376 connected thereto to rotate. However, at this time, when the gear ring 376 rotates in the reverse direction, the paddle plate 372 can achieve a certain degree of flipping. On the contrary, when the gear ring 376 rotates in the forward direction, the paddle plate 372 limits the rotation of the gear ring 376, thereby achieving unidirectional rotation of the gear ring 375 (the difference between the two states of the front and rear paddle plates 372 when the gear ring 376 rotates in the forward and reverse directions can be achieved by changing the distribution of the paddle plates 372 in the ring sleeve 369, that is, the front and rear paddle plates 372 are symmetrically distributed compared to the center line of the straight plate 367);

[0103] It is hereby explained that the ring sleeve 369 at the corresponding position of the full-tooth gear ring 375 is rotatably mounted with the horizontal shaft, and the other ring sleeve 369 is clamped and mounted with the horizontal shaft;

[0104] The resetting process of the band plate 378 (only by the incomplete gear ring 375 being connected with the band plate 378):

[0105] When the incomplete tooth ring gear 375 rotates a certain angle, the smooth curved surface of its outer wall is connected with the band plate 378 (the band plate 378 is no longer engaged with the incomplete tooth ring gear 375). At this time, the band plate 378 moves to the initial position under the restoring action of the reset spring 392, and reciprocates in this way to achieve multiple energy storage.

[0106] Reference Figure 6 , Figure 8 , Fig. 9 and Fig.14 It can be known that the end of the band plate 378 away from the gear ring 375 is clamped and installed with a strip plate 381 that is slidably clamped and installed with the vertical plate 377, the end face of the strip plate 381 away from the vertical plate 377 is clamped and installed with a support 382, ​​and the end face of the support 382 close to the middle position of the strip plate 381 is clamped and installed with a ball rod 383, the vertical section of the right-angle plate 31 is symmetrically clamped and installed with an angle frame 384 on the end face close to the strip plate 381, and the cross-sectional shape of the angle frame 384 is L-shaped, and the vertical section of the angle frame 384 is through-rotatably installed with a convex column 385, the outer wall of the convex column 385 away from the right-angle plate 31 is provided with a snake mouth groove 386, the outer wall of the convex column 385 away from the right-angle plate 31 is provided with a straight groove 387 that is compatible with the snake mouth groove 386, and the outer wall of the convex column 385 close to the right-angle plate 31 is clamped and installed with a pulley 388;

[0107] Reference Figure 4 , Figure 6 , Figure 7 , Figure 8 and Fig.10It can be seen that the preparation unit 4 includes: an air pipe 393, which is one in number and is installed in the vertical section of the right-angle plate 31 in a through-type snap-fitting manner; an air plug 41, which is installed in the air pipe 393 in a plug-in manner, and the air plug 41 is installed in a sliding snap-fitting manner with the air pipe 393; a stand 42, which is one in number and is installed in a sliding snap-fitting manner at one end of the vertical plate 377 close to the end face of the air pipe 393; an air column 43, which is one in number and is snap-fitted at the middle position of the end face of the stand 42 close to the axis of the convex column 385; a telescopic spring 44, which is sleeved and installed in the middle position of the outer wall of the air plug 41, and the air plug 41 is located between the air pipe 393 and the stand 42; a positive electrode sheet 45, which is snap-fitted at the end face of the stand 42 away from the right-angle plate 31; a negative electrode sheet 46, which is installed in the vertical section of the vertical plate 377 by snap-fitting, and the negative electrode sheet 46 is positively distributed relative to the positive electrode sheet 45;

[0108] The airbag 47 is snap-fitted and installed on the end face of the vertical section of the right-angle plate 31 away from the magnetron generator 27, and the airbag 47 is plug-fitted and installed with the air pipe 393; the air duct 48 is snap-fitted and installed on the inner wall of the end of the chassis 1 away from the insulating plate 21 through the mounting seat, and the air duct 48 is connected with the airbag 47; there is at least one spray valve 49, which is plug-fitted and installed on the outer wall of the air duct 48 close to the insulating plate 21.

[0109] Method for adjusting the instantaneous sudden temperature rise in the chassis 1 by the preparation unit 4:

[0110] First, under the control of the band plate 378, the strip plate 381 synchronously drives the support 382 to move away from the right angle plate 31. During this process, the ball rod 383 continuously moves with the outer wall snake mouth groove 386 of the convex coupling column 385 near one end thereof, until the ball rod 383 enters the outer wall straight groove 387 of the convex coupling column 385 near one end thereof;

[0111] Next, the rotation state of the lower convex column 385 driven by the ball rod 383 is transmitted to another convex column 385 through the pulley 388 (in specific implementation, the transmission between the pulleys 388 can be realized by a belt). After that, through the mutual movement between the snake mouth groove 386 on the outer wall of the convex column 385 at one end away from the support 382 and the air column 43, the air column 43 is forced to drive the stand 42 under the guidance of the vertical plate 377, and control the positive electrode sheet 45 to move toward the negative electrode sheet 46 until the two are in contact. At the same time, the air column 43 enters the straight groove 387 in the convex column 385 at one end close to the stand 42.

[0112] Finally, when the gas column 43 enters the straight groove 387, the telescopic spring 44 in the stretched state, under the action of its own elastic potential energy, controls the gas plug 41 to overcome the friction between the gas column 43 and the convex column 385 and the friction between the gas plug 41 and the air pipe 393, and moves into the air pipe 393 (through the resetting of the telescopic spring 44, the energy accumulated by the collision between the column 26 and the spring rod 33 is instantly released), until the gas inside the air bag 47 is filled into the air pipe 48 with a certain pressure, and finally sprayed into the chassis 1 through the spray valve 49 (at the same time, the wind plate 17 is opened to allow the air outlet 15 to circulate with the external air. In specific implementation, the wind plate 17 can be driven by the electric slider to slide to the specified position), thereby providing an additional cooling solution, increasing the heat dissipation area and the flow rate of the cooling medium, thereby more effectively reducing the instantaneous temperature rise of the internal environment of the microwave ablation device, improving the reliability of the cooling system, and enhancing the fault tolerance of the equipment (in specific implementation, the air bag 47 can be connected to the external air through an external hose, and the specific role of the air bag 47 can refer to the air bag 47 in the sphygmomanometer);

[0113] It is hereby explained that through the contact between the positive electrode sheet 45 and the negative electrode sheet 46 , in a specific implementation, an alarm device (electrically connected to the positive electrode sheet 45 and the negative electrode sheet 46 ) can be added to the outside to remind the operator to clean the heat dissipation port 14 .

[0114] The microwave RDN ablation device provided by the present invention has the following working principle: Step 1: First, the column 26 collides with the spring rod 33, and then the outer rack 34 is controlled by the spring rod 33 to mesh with the sun gear 36, and the inner rack 38 synchronously drives the wall plate 361 to move away from the double ear plate 32 during the meshing process between the planetary gear 37 and the sun gear 36, until the wedge plate 363 and the gear ring 375 move relative to each other;

[0115] Step 2: Then, the gear ring 376 is controlled by the gear ring 375 to move relative to the shift plate 372. After that, the ring sleeve 369 drives the band plate 378 to move away from the right-angle plate 31 under the extrusion of the shift plate 372, until the ball rod 383 continuously moves relative to the snake mouth groove 386 of the outer wall of the convex coupling column 385 under the control of the support 382;

[0116] Step 3: Finally, the transmission effect of the pulley 388 is used to cause the convex column 385 on the side close to the stand 42 to rotate synchronously. In this process, the air column 43 drives the stand 42 to move away from the right-angle plate 31 under the guidance of the vertical plate 377 through the snake-mouth groove 386, until the air column 43 is engaged with the straight groove 387. Thereafter, the air plug 41 moves toward the air pipe 393 under the restoring action of the telescopic spring 44, and finally the gas in the air pipe 48 is evenly blown to each component through the spray valve 49.
