Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a thyroid nodule ablation treatment device that can automatically attract cystic fluid. Background Technology

[0002] Thyroid nodules are lumps or nodules that appear in the thyroid gland. Most are benign and usually do not become cancerous. For smaller benign nodules, doctors usually recommend observation, but for larger nodules or patients with significant symptoms, ablation therapy is an effective treatment method.

[0003] Ablation therapy uses high-energy sound waves or radiofrequency currents to directly target the nodule tissue, causing thermal damage that leads to its absorption. This treatment method does not require surgery, leaves no obvious scars, and has a short recovery period. In thyroid nodule ablation therapy, under ultrasound guidance, an ablation needle is inserted into the nodule. Heat generated by radiofrequency, microwave, or laser is then used to cause degeneration and necrosis of the local nodule cells, achieving the therapeutic goal. However, current thyroid nodule ablation instruments require changing different tools for cyst fluid aspiration and irrigation, which is inconvenient and affects the surgical process. Furthermore, changing tools during these procedures is dangerous and can easily cause injury to the patient.

[0004] Therefore, in response to the shortcomings of the existing technology, a thyroid nodule ablation treatment device that can automatically aspirate cystic fluid has been developed, which can quickly switch between the flushing and aspiration processes during thyroid nodule ablation treatment and improve the safety of the procedure. Summary of the Invention

[0005] To overcome the inconvenience of existing thyroid nodule ablation devices, which require changing different tools and repeated operations for cyst fluid extraction and irrigation, this invention provides a thyroid nodule ablation treatment device that can automatically aspirate cyst fluid, enabling rapid switching between irrigation and extraction during thyroid nodule ablation treatment and improving surgical safety.

[0006] The technical solution is as follows: A thyroid nodule ablation treatment device that can automatically attract cystic fluid includes a mounting frame, a first guide, a syringe, an extraction and flushing mechanism, and a guide support mechanism. The first guide is connected inside the mounting frame, and the syringe is connected to the bottom of the first guide. The extraction and flushing mechanism is provided on the first guide, and the guide support mechanism is provided on the mounting frame.

[0007] As an improvement to the above solution, the extraction and flushing mechanism includes a rotating mounting column, a guide tube, a fixed frame, a rubber joint, and a first spring. The rotating mounting column is rotatably connected inside the first guide member. Guide tubes are connected to both the front and rear sides inside the rotating mounting column. The fixed frame is rotatably connected to the upper part of the rotating mounting column. Multiple rubber joints are slidably connected to the upper right part of the fixed frame. The rubber joints are pressed and fitted with the fixed frame. The first spring is connected between each rubber joint and the fixed frame.

[0008] As an improvement to the above solution, the guide support mechanism includes a fixed plate, a first guide frame, a first sliding frame, a second guide member, a second spring, and a locking plate. The second guide member is slidably connected to both the front and rear sides of the mounting frame. The locking plate is slidably connected to the interior of each second guide member. Multiple second springs are connected between each locking plate and the adjacent second guide member. The first sliding frame is connected to each second guide member. The first guide frame is slidably connected to each first sliding frame. The fixed plate is rotatably connected between the bottoms of the first guide frames.

[0009] As an improvement to the above solution, a switching mechanism is also included. The switching mechanism includes a guide rod, a third spring, a second sliding frame, a connecting frame, a telescopic component, a fourth spring, and a rotating column. The front and rear parts of the fixed frame are connected to the guide rods, and the second sliding frame is slidably connected between the guide rods. The front and rear parts of the second sliding frame are connected to the fixed frame by the third spring. The middle part of the second sliding frame is connected to the connecting frame, and the top of the rotating mounting column is connected to the rotating column. The front and rear parts of the connecting frame are slidably connected to the telescopic component, and the telescopic component is connected to the connecting frame by the fourth spring. The connecting frame is slidably connected to the rotating column through the telescopic component.

[0010] As an improvement to the above solution, a stabilizing mechanism is also included. The stabilizing mechanism includes a pusher, a fifth spring, a rotating frame, a rubber component, and a support component. The pusher is slidably connected to each of the first sliding frames. The pusher is connected to the fifth spring between each of the adjacent first sliding frames. The rotating frame is rotatably connected to each of the pushers. The rubber component is connected to each of the rotating frames. The support component is connected to the left side of the mounting frame. The support component and the pusher are in a pressing fit.

[0011] As an improvement to the above solution, a locking mechanism is also included. The locking mechanism includes a locking wheel, a locking pin, and a sixth spring. The upper part of the fixing plate is slidably connected to the locking pin, and the front and rear parts of the locking pin are connected to the fixing plate with the sixth spring. The lower part of the first guide frame is connected to the locking wheel, and the locking wheel engages with the locking pin.

[0012] As an improvement to the above solution, a disinfection and absorption mechanism is also included. The disinfection and absorption mechanism includes a second guide frame, a third sliding frame, an absorption pad, and a seventh spring. The second guide frame is connected to the right side of the mounting frame, and the third sliding frame is slidably connected to the second guide frame. The absorption pad is connected to the bottom of the third sliding frame, and the seventh spring is connected to both the front and rear parts of the third sliding frame and the second guide frame.

[0013] As an improvement to the above scheme, the first guide frame is an arc-shaped structure, which allows the mounting frame to move around the patient's neck to find the right spot during lowering.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention drives the catheter to rotate by rotating the mounting column. When the catheter passes through the rubber joint in sequence, the operation of connecting the rubber joint with the catheter under the action of the first spring can achieve a rapid switching between flushing and aspiration during thyroid nodule ablation treatment, thereby improving the safety of the operation.

[0015] 2. This invention uses a second sliding frame in conjunction with a connecting frame to move a telescopic component. The telescopic component controls the rotation of the rotating column, which helps physicians to precisely control the rotation and docking of the catheter, thereby improving surgical safety.

[0016] 3. The present invention uses the expanding member to squeeze the pushing member, causing the pushing members to move away from each other, thereby driving the rubber member to move and cooperate with the first guide frame. This can stabilize the position of the mounting frame and improve the safety of the operation.

[0017] 4. The present invention uses a locking pin that cooperates with a locking wheel under the action of a sixth spring to fix the position of the first guide frame, thereby stabilizing the first guide frame, preventing accidental rotation of the first guide frame, and improving the safety of the operation.

[0018] 5. The present invention allows the absorbent pad to move together with the mounting frame via the third sliding frame and the second guide frame, thereby achieving the effect of disinfecting the lesion site and absorbing the overflowing cyst fluid, thus improving the safety of the operation.

Detailed Implementation

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] A thyroid nodule ablation treatment device that can automatically aspirate cystic fluid, such as Figure 1 and Figure 2 As shown, it includes a mounting frame 1, a first guide 2, a syringe 3, an extraction and flushing mechanism 4, and a guide support mechanism 5. The first guide 2 is connected inside the mounting frame 1, and the syringe 3 is connected to the bottom of the first guide 2. The first guide 2 is provided with an extraction and flushing mechanism 4 for extracting and flushing the cyst fluid. The mounting frame 1 is provided with a guide support mechanism 5 for assisting the physician in controlling the needle insertion position.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, the extraction and rinsing mechanism 4 includes a rotating mounting column 40, a conduit 41, a fixing frame 42, rubber joints 43, and a first spring 44. The rotating mounting column 40 is rotatably connected inside the first guide member 2. The conduit 41 is connected to both the front and rear sides inside the rotating mounting column 40. The fixing frame 42 is rotatably connected to the upper part of the rotating mounting column 40. Multiple rubber joints 43 are slidably connected to the upper right part of the fixing frame 42. The rubber joints 43 are pressed and fitted with the fixing frame 42. The first spring 44 is connected between each rubber joint 43 and the fixing frame 42. The rotating mounting column 40 drives the conduit 41 to rotate. When the conduit 41 passes through the rubber joints 43 in sequence, the rubber joints 43 are connected to the conduit 41 under the action of the first spring 44, thus switching between extraction and rinsing.

[0033] like Figure 1 , Figure 5 and Figure 6 As shown, the guide support mechanism 5 includes a fixed plate 50, a first guide frame 51, a first sliding frame 52, a second guide member 53, a second spring 54, and a locking plate 55. The mounting frame 1 has second guide members 53 slidably connected to both its front and rear sides. Locking plates 55 are slidably connected inside each second guide member 53. Multiple second springs 54 connect each locking plate 55 to an adjacent second guide member 53. First sliding frames 52 are connected to each second guide member 53, and first guide frames 51 are slidably connected to each first sliding frame 52. The first guide frames 51 are all arc-shaped structures, which allow the mounting frame to... The frame 1 can move around the patient's neck to locate the injection point. The bottom of the first guide frame 51 is rotatably connected to the fixing plate 50. By fixing the fixing plate 50 to the hospital bed, when moving the mounting frame 1, it cooperates with the second guide member 53 and the first sliding frame 52 to move left and right along the first guide frame 51 to adjust the position of the syringe 3. At the same time, the mounting frame 1 is pressed down, so that the mounting frame 1 moves downward on the second guide member 53 to insert the needle into the lesion site. At the same time, the locking plate 55 is fixed to the mounting frame 1 under the action of the second spring 54, which facilitates subsequent extraction and flushing operations.

[0034] This device can be used during thyroid nodule ablation treatment. First, the device is installed on the treatment bed using the fixing plate 50. Then, when moving the mounting frame 1, the second guide 53 and the first sliding frame 52 work together to move it left and right along the first guide frame 51, adjusting the position of the syringe 3. Simultaneously, the mounting frame 1 is pressed downwards, causing it to move downwards on the second guide 53 to insert the needle into the lesion. At the same time, the locking plate 55, under the action of the second spring 54, fixes the mounting frame 1, facilitating subsequent extraction and flushing operations. When cyst fluid extraction and lesion flushing are required, the flushing tube and extraction tube are connected... The catheter 41 is connected to the rubber connector 43. Then, the mounting post 40 is rotated to drive the catheter 41 to rotate. When the catheter passes through the rubber connector 43, the first spring 44 causes the rubber connector 43 to engage with the catheter 41, switching between extraction and flushing. After the treatment is completed, the mounting frame 1 is pulled upward to remove the syringe 3. The operation of rotating the mounting post 40 to drive the catheter 41 to rotate and then engaging the rubber connector 43 with the catheter 41 under the action of the first spring 44 can achieve rapid switching between flushing and extraction during thyroid nodule ablation treatment, improving the safety of the surgery.

[0035] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a switching mechanism 6 for assisting physicians in precisely controlling the rotation and docking of the catheter 41. The switching mechanism 6 includes a guide rod 60, a third spring 61, a second sliding frame 62, a connecting frame 63, a telescopic component 631, a fourth spring 632, and a rotating column 64. The front and rear parts of the fixed frame 42 are connected to the guide rod 60, and the second sliding frame 62 is slidably connected between the guide rods 60. The front and rear parts of the second sliding frame 62 are connected to the fixed frame 42 by the third spring 61, and the connecting frame 63 is connected to the middle of the second sliding frame 62. The top of the rotating mounting column 40 is connected to the rotating column 64. The front and rear parts of the connecting frame 63 are slidably connected to the telescopic component 631, and the telescopic component 631 is connected to the connecting frame 63 by the third spring 64. The fourth spring 632 and the connecting frame 63 are slidably connected to the rotating column 64 via the telescopic member 631. Pressing down on the second sliding frame 62 causes the connecting frame 63 to move downward. When the second sliding frame 62 moves downward, it compresses the third spring 61. The downward movement of the connecting frame 63 causes the telescopic member 631 to move. When the telescopic member 631 moves to the lower part of the rotating column 64, the fourth spring 632 rebounds, causing the telescopic members 631 to move closer together. When the second sliding frame 62 is released, the third spring 61 rebounds, causing the second sliding frame 62 to move upward. The telescopic member 631 drives the rotating mounting column 40 to rotate through the sliding groove on the rotating column 64, thus precisely controlling the rotation and docking of the conduit 41.

[0036] Using the switching mechanism 6 of this device, physicians can precisely control the rotation and docking of catheter 41. When switching between extraction and flushing, pressing down on the second sliding frame 62 causes the connecting frame 63 to move downwards. As the second sliding frame 62 moves downwards, it compresses the third spring 61. The downward movement of the connecting frame 63 causes the telescopic component 631 to move. When the telescopic component 631 moves to the lower part of the rotating column 64, the fourth spring 632 rebounds, causing the telescopic components 631 to move closer together. When the second sliding frame 62 is released, the rebound of the third spring 61 causes the second sliding frame 62 to move upwards. The telescopic component 631, through the groove on the rotating column 64, drives the rotating mounting column 40 to rotate, thus precisely controlling the rotation and docking of catheter 41. By cooperating with the connecting frame 63, the second sliding frame 62 moves the telescopic component 631, and the telescopic component 631 controls the rotation of the rotating column 64, thus assisting physicians in precisely controlling the rotation and docking of catheter 41 and improving surgical safety.

[0037] like Figure 1 and Figure 9 As shown, it also includes a stabilizing mechanism 7 for stabilizing the mounting bracket 1. The stabilizing mechanism 7 includes a pusher 70, a fifth spring 71, a rotating frame 72, a rubber component 73, and a support 74. Pushers 70 are slidably connected to each of the first sliding frames 52. Each pusher 70 is connected to a fifth spring 71 between itself and an adjacent first sliding frame 52. Each pusher 70 is rotatably connected to a rotating frame 72. Each rotating frame 72 is connected to a rubber component 73. A support 74 is connected to the left side of the mounting bracket 1. The support 74 presses against the pusher 70. When the mounting frame 1 moves downwards and the syringe 3 is inserted into the patient's body, it will cause the spreading member 74 to move downwards and squeeze the pushing member 70, so that the pushing members 70 move away from each other and drive the rotating frame 72 to move. The rotating frame 72 moves away from each other and drives the rubber parts 73 to move away from each other. The rubber parts 73 move away from each other and squeeze the first guide frame 51, stabilizing the position of the mounting frame 1. When the mounting frame 1 returns to its original position, the fifth spring 71 rebounds and drives the pushing member 70 to return to its original position, so that the rubber parts 73 move closer to each other, and the mounting frame 1 can move and adjust normally.

[0038] Using the stabilizing mechanism 7 of this device, the mounting frame 1 can be stabilized. When the mounting frame 1 moves downward and drives the syringe 3 into the patient's body, it will drive the expanding member 74 to move downward and squeeze the pushing member 70, causing the pushing members 70 to move away from each other and drive the rotating frame 72 to move. The rotating frame 72 moves away from each other and causes the rubber parts 73 to move away from each other. The rubber parts 73 move away from each other and squeeze the first guide frame 51, stabilizing the position of the mounting frame 1. When the mounting frame 1 returns to its original position, the fifth spring 71 rebounds and drives the pushing member 70 to return to its original position, causing the rubber parts 73 to move closer together. The mounting frame 1 can move and adjust normally. By using the expanding member 74 to squeeze the pushing member 70, causing the pushing member 70 to move away from each other and driving the rubber parts 73 to move in conjunction with the first guide frame 51, the position of the mounting frame 1 can be stabilized, improving the safety of the operation.

[0039] like Figure 1 and Figure 10 As shown, it also includes a locking mechanism 8 for stabilizing the first guide frame 51. The locking mechanism 8 includes a locking wheel 80, a locking pin 81 and a sixth spring 82. The locking pin 81 is slidably connected to the upper part of the fixing plate 50. The sixth spring 82 is connected between the front and rear parts of the locking pin 81 and the fixing plate 50. The locking wheel 80 is connected between the lower parts of the first guide frame 51. The locking wheel 80 and the locking pin 81 are engaged. Under the action of the sixth spring 82, the locking pin 81 engages with the locking wheel 80, which can fix the position of the first guide frame 51.

[0040] Using the locking mechanism 8 of this device, the first guide frame 51 can be stabilized. The locking pin 81, under the action of the sixth spring 82, cooperates with the locking wheel 80 to fix the position of the first guide frame 51 and prevent the first guide frame 51 from rotating accidentally. When it is necessary to rotate and adjust the first guide frame 51, the locking pin 81 can be pulled. Through the above-mentioned operation of locking pin 81 cooperating with the locking wheel 80 under the action of the sixth spring 82, the position of the first guide frame 51 is fixed, which can achieve the effect of stabilizing the first guide frame 51, preventing the first guide frame 51 from rotating accidentally, and improving the safety of the operation.

[0041] like Figure 1 and Figure 10As shown, it also includes a disinfection and absorption mechanism 9 for disinfecting the lesion site and absorbing the overflowing cyst fluid. The disinfection and absorption mechanism 9 includes a second guide frame 90, a third sliding frame 91, an absorption pad 92, and a seventh spring 93. The second guide frame 90 is connected to the right side of the mounting frame 1. The third sliding frame 91 is slidably connected to the second guide frame 90. The absorption pad 92 is connected to the bottom of the third sliding frame 91. The seventh spring 93 is connected to both the front and rear parts of the third sliding frame 91 and the second guide frame 90. The absorption pad 92 moves together with the mounting frame 1 through the third sliding frame 91 and the second guide frame 90. When it moves downward with the mounting frame 1, it wipes and cleans the overflowing cyst fluid at the lesion site. At the same time, alcohol can be applied to the upper part of the absorption pad 92 to disinfect the injection site of the patient.

[0042] Using the disinfection and absorption mechanism 9 of this device, the lesion site of the patient can be disinfected and the overflowing cystic fluid can be absorbed. The absorption pad 92 moves together with the mounting frame 1 via the third sliding frame 91 and the second guide frame 90. When it moves downward with the mounting frame 1, the overflowing cystic fluid at the lesion site is wiped clean. At the same time, alcohol can be applied to the upper part of the absorption pad 92 to disinfect the injection site of the patient. Through the operation of the absorption pad 92 moving together with the mounting frame 1 via the third sliding frame 91 and the second guide frame 90, the lesion site of the patient can be disinfected and the overflowing cystic fluid can be absorbed, thereby improving the safety of the operation.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
