Description

Technical Field

[0001] This invention relates to the field of medical devices, and more specifically, to a radiofrequency ablation fixation device based on information data. Background Technology

[0002] Radiofrequency ablation can precisely target the affected area and is recognized worldwide as the best method for treating tumors. However, the ablation process can be quite painful and unbearable for patients, leading to significant movement during treatment and causing the radiofrequency needle to detach from the patient. This requires multiple insertions. Therefore, it is necessary to fix the patient's arm or body parts, but certain locations cannot be fixed by devices and require manual fixation.

[0003] For example, the Chinese utility model patent (application number: CN202223044013.8) discloses a "fixation device for the arm of a patient undergoing liver radiofrequency ablation." The specification states that radiofrequency ablation, as a minimally invasive treatment for liver cancer, is the most common thermal ablation modality worldwide. Its principle is to use electromagnetic heat energy generated by electromagnetic waves with frequencies less than 30MHz to cause tissue coagulation and necrosis, thereby inactivating the tumor. CT-guided percutaneous RFA, as a minimally invasive treatment technique, has been widely used for liver tumors in recent years. Due to the requirements of RFA surgery, the CT fixation device is simple and the bed space is relatively narrow. When interventional radiology nurses perform CT-guided general anesthesia RFA treatment, in order to better expose the surgical field and ensure ablation... Treatment efficacy and minimizing arm injury during the movement of the examination bed into the CT chamber are crucial aspects of RFA surgery. Patient positioning is critical, requiring immobilization. Typically, the right arm or both arms are raised and crossed above the head. Due to the lack of specialized fixation devices, arms of patients under general anesthesia are prone to slipping off the body and cannot be securely fixed. Furthermore, the arms remain in a hyperextended or bent position for extended periods throughout the procedure, easily causing postoperative arm pain. In existing technologies, CT beds are relatively narrow, requiring multiple entries and exits from the CT chamber. The support pads are prone to slipping and are made of soft material, resulting in poor arm support and fixation, thus affecting the surgical procedure. The aforementioned patent demonstrates the deficiencies of existing technologies.

[0004] Therefore, we have made improvements to this by proposing a radiofrequency ablation fixation device based on information data. Summary of the Invention

[0005] The purpose of this invention is to address the issue that existing devices cannot fix objects in certain locations, requiring manual fixation.

[0006] To achieve the above-mentioned objectives, the present invention provides the following radiofrequency ablation fixation device based on information data to improve the aforementioned problems.

[0007] The application is as follows:

[0008] A radiofrequency ablation fixation device based on information data includes a radiofrequency component, a radiofrequency needle disposed within the radiofrequency component, a hollow circular frame disposed on the radiofrequency needle, and a fixation component disposed on the hollow circular frame. The fixation component includes three first telescopic rods and second telescopic rods, with a fixing rod rotatably mounted on both sides of one end of each first telescopic rod and second telescopic rod. A circular groove is formed on the hollow circular frame, and one end of each first telescopic rod and second telescopic rod is slidably connected to the inner wall of the circular groove. A first gear is rotatably mounted on the upper end of the inner wall of one end of each first telescopic rod via a first rotating shaft, and a second gear is rotatably mounted on the lower end of the inner wall of one end of each second telescopic rod. Two opposing first telescopic rods and second telescopic rods form a group, and a resilient elastic rope is rotatably connected between the middle of each group of first telescopic rods and second telescopic rods. A compression straight groove block is disposed on each group of first telescopic rods and second telescopic rods.

[0009] As a preferred technical solution of this application, a plurality of straight grooves are equidistantly provided on the outer wall of the annular groove, and a straight groove block is rotatably connected to the inner wall of each straight groove.

[0010] As a preferred technical solution of this application, a propulsion component is provided inside the hollow circular frame. The propulsion component is used for precise radiofrequency ablation treatment. The propulsion component includes a first annular ring and a second annular ring. A first toothed rod is engaged on the first annular ring, and a second toothed rod is engaged on the second annular ring. A circular push block is provided inside the hollow circular frame. The circular push block is rotatably connected to the first toothed rod and the second toothed rod.

[0011] As a preferred technical solution of this application, the first annular ring is meshed with the first gear, and the second annular ring is meshed with the second gear.

[0012] As a preferred technical solution of this application, a first annular groove is provided on the first annular ring, and a plurality of first limiting rods are slidably connected inside the first annular groove. Each first limiting rod is fixedly connected to the inner wall of the hollow circular frame. A second annular groove is provided below the second annular ring, and a plurality of second limiting rods are slidably connected inside the second annular groove. Each second limiting rod is fixedly connected to the inner wall of the hollow circular frame.

[0013] As a preferred technical solution of this application, a cooling component is provided around the hollow circular frame. The cooling component is used to cool the skin. The cooling component includes several telescopic condenser tubes. An arc-shaped blood-absorbing plate is rotatably installed on each telescopic condenser tube. A flexible rod is fixedly connected to each telescopic condenser tube. A rotating wheel is fixedly connected to the flexible rod. Several U-shaped frames are fixedly connected at equal intervals around the hollow circular frame. The rotating wheel is rotatably connected to the inner wall of the U-shaped frame.

[0014] As a preferred technical solution of this application, a ring is fixedly connected to the U-shaped frame, and a circular through groove is opened between the ring and the U-shaped frame, through which the telescopic condenser tube passes.

[0015] As a preferred technical solution of this application, each of the telescopic condenser tubes is fitted with a spring, and one end of the spring is fixedly connected to the arc-shaped blood-absorbing plate.

[0016] As a preferred technical solution of this application, a plurality of U-shaped condenser tubes are fixedly connected at equal intervals on the arc-shaped blood-absorbing plate, and each U-shaped condenser tube is fixedly connected to a telescopic condenser tube.

[0017] As a preferred technical solution of this application, the lower end of the hollow circular frame has a circular through groove, the radio frequency needle passes through the circular through groove, and the radio frequency needle is fixedly connected to the circular push block.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] In the scheme of this application:

[0020] 1. In order to solve the fixation problem in the prior art, this application sets up a fixation component that enables the fixing rod on the first and second sets of telescopic rods to be rotated to 180 degrees when the radiofrequency needle is inserted into the human body. At this time, a tough elastic rope is connected to the middle of the fixing rod to fix the human body part at the insertion position, thereby preventing the patient from moving around uncomfortably and avoiding the radiofrequency needle changing position due to the patient's movement. Therefore, it is not necessary to insert the radiofrequency needle multiple times.

[0021] 2. In order to solve the problem of insertion in special positions in the prior art, this application, through the setting of a fixing component, realizes that when special positions cannot be mechanically fixed and manual operation is required, the fixing rod rotatably installed on a set of first telescopic rods and second telescopic rods is adjusted to 90 degrees to form a hand grip, so that medical personnel can manually insert and fix it. This can effectively reduce the pain of multiple insertions for patients when treating special positions, and can also accurately insert into the human body.

[0022] 3. To address the issue of preventing skin burns in existing technologies, this application incorporates a cooling component. When the radiofrequency needle is inserted into the body, the telescopic cooling tube is manually adjusted and flipped down via a rotating wheel and a flexible rod. Then, the six arc-shaped blood-sucking plates are rotated into a ring shape, closely adhering to the insertion site of the radiofrequency needle. At this point, the U-shaped cooling tube on the arc-shaped blood-sucking plates is in close contact with the skin. During the ablation procedure, the cooling tube provides cooling to the heated area, effectively preventing skin burns during the ablation process.

[0023] 4. In order to solve the problem of hemostasis in the prior art, this application, through the setting of a cooling component, realizes that when the temperature around the wound is relatively high during the ablation process, there may be a situation where the bleeding does not stop. The arc-shaped blood-absorbing plate and the spring can stop the bleeding and squeeze the wound, which can prevent a large amount of blood from flowing out, thereby effectively protecting the human body and preventing the human body from shock due to massive bleeding.

[0024] 5. In order to solve the problem of protecting the radiofrequency needle in the prior art, this application has set up a cooling component to realize that when the radiofrequency needle may fall when the human body moves wildly, the spring will extend forward after the human body tissue is no longer pressing against it, thereby covering the radiofrequency needle and effectively protecting the needle tip or needle body from deformation when it falls to the ground.

[0025] 6. To address the problem of precisely inserting radiofrequency needles into the human body in existing technologies, this application, through the design of a fixing component and a pushing component, enables medical personnel to squeeze the first and second gears in each set of first and second telescopic rods when holding the fixing rod. These gears mesh with the first and second annular rings, causing them to rotate. This, in turn, drives the first and second locking rods to rotate, pushing the circular pushing block downwards. This pushes the radiofrequency needle downwards and slowly moves it into the human body, precisely reaching the location of the lesion and effectively performing radiofrequency ablation on the lesion.

[0043] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0044] As in the background technology, but in special locations, it cannot be fixed by a device and requires manual fixation.

[0045] To address this technical problem, the present invention provides a radiofrequency ablation fixation device based on information data, which is applied to manual integrated ablation.

[0046] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 11 The radiofrequency ablation fixation device based on information data specifically includes:

[0047] Radio frequency (RF) component 1 includes an RF needle 101, a hollow circular frame 102 on the RF needle 101, and a fixing component 3 on the hollow circular frame 102. The fixing component 3 includes three first telescopic rods 303 and second telescopic rods 310. Each first telescopic rod 303 and second telescopic rod 310 has a fixing rod 301 rotatably mounted on both sides of one end. A circular groove 304 is formed in the hollow circular frame 102. One end of each first telescopic rod 303 and second telescopic rod 310 is slidably connected to the inner wall of the circular groove 304. The upper end of the inner wall of one end of each first telescopic rod 303 passes through… A first gear 306 is rotatably mounted on a first rotating shaft 307. A second gear 309 is rotatably mounted on the lower inner wall of one end of each second telescopic rod 310. Three first telescopic rods 303 and three second telescopic rods 310 are arranged such that the first gear 306 is rotatably mounted on the upper inner wall of one first telescopic rod 303, and the second gear 309 is rotatably mounted on the lower inner wall of one second telescopic rod 310. These first telescopic rods 303 and second telescopic rods 310 form a group. Two opposing first telescopic rods 303 and second telescopic rods 310 form another group. Each group of first telescopic rods 303 and second telescopic rods 310... The 10th section is rotatably connected by a resilient elastic cord 302. Each set of telescopic first telescopic rods 303 and second telescopic rods 310 is equipped with a compression straight groove block 308. There are a total of three sets of first telescopic rods 303 and second telescopic rods 310, but generally only two sets are needed to fix the human body. When it is necessary to fix it to the arm or thigh, the front and rear sets are adjusted respectively, and then the resilient elastic cord 302 rotatably connected to the fixing rod 301 is used to clamp and fix it at the front and rear positions of the radiofrequency needle 101. When a larger area needs to be fixed, it is adjusted to the left and right sets, and then the radiofrequency needle is inserted. The left and right sides of the 101 are clamped and fixed by the fixing rods 301. When inserting into some special places, manual fixation is required. At this time, the fixing rods 301, which are rotatably installed on the first telescopic rod 303 and the second telescopic rod 310, are rotated 90 degrees to form a handle. This allows medical staff to hold and fix the needle. At the same time, the medical staff use the patient's imaging data to determine the size and specific location of the liver cancer, so that the medical staff can accurately insert the radiofrequency needle 101 into the specific location of the liver cancer, thereby performing precise ablation treatment.

[0048] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0049] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0050] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0051] Example 1

[0052] Please refer to Figure 1 , Figure 8 A radiofrequency ablation fixation device based on information data has several straight grooves evenly spaced on the outer wall of its annular through groove 304. Each straight groove has a straight groove block 305 rotatably connected to its inner wall. After the radiofrequency needle 101 is inserted into the human body, it is necessary to know the precise insertion distance in a timely manner. At this time, a scale dial is formed by the straight groove block 305, which can be used to observe the movement of the first telescopic rod 303 and the second telescopic rod 310 to the corresponding straight groove block 305 position, thereby allowing for timely understanding of the precise insertion position.

[0053] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 9 A radiofrequency ablation fixation device based on information data includes a hollow circular frame 102 with an internal propulsion component 4 for precise radiofrequency ablation treatment. The propulsion component 4 includes a first annular ring 403 and a second annular ring 404. The outer rings of the first annular ring 403 and the second annular ring 404 have toothed grooves, and the inner rings are threaded. A first retaining toothed rod 401 is engaged on the first annular ring 403, and a second retaining toothed rod 402 is engaged on the second annular ring 404. A circular push block 103 is provided inside the hollow circular frame 102. The circular push block 103 is rotatably connected to the first retaining toothed rod 401 and the second retaining toothed rod 402. The retaining teeth on the first retaining toothed rod 401 and the second retaining toothed rod 402 are transverse and do not contact each other, so they do not affect each other. The first annular ring 403 only contacts the first retaining toothed rod 402 and does not contact the second retaining toothed rod 401, and the second annular ring 404 is the opposite.

[0054] Example 2

[0055] The radiofrequency ablation fixation device based on information data provided in Example 1 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3As shown, the first annular ring 403 is meshed with the first gear 306, and the second annular ring 404 is meshed with the second gear 309. The first annular ring 403 is located above the annular groove 304 and only contacts the first gear 306, thereby driving the first toothed rod 401 to rotate. The second annular ring 404 is located below the annular groove 304 and only contacts the second gear 309, thereby driving the second toothed rod 402 to rotate, thereby pushing the circular push block 103 downward. This allows the radiofrequency needle 101 to slowly move to the final precise distance after entering the human body, thereby precisely ablating the lesion.

[0056] Furthermore, such as Figure 7 and Figure 12 As shown, a first annular groove 405 is formed on the first annular ring 403, and a plurality of first limiting rods 406 are slidably connected inside the first annular groove 405. Each first limiting rod 406 is fixedly connected to the inner wall of the hollow circular frame 102. A second annular groove is formed on the lower part of the second annular ring 404, and a plurality of second limiting rods 407 are slidably connected inside the second annular groove. Each second limiting rod 407 is fixedly connected to the inner wall of the hollow circular frame 102, which facilitates the limiting of the first annular ring 403 and the second annular ring 404 without affecting their rotation.

[0057] Example 3

[0058] The radiofrequency ablation fixation device based on information data provided in Embodiment 1 or 2 is further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 10 As shown, a cooling component 2 is provided around the hollow circular frame 102. The cooling component 2 is used to cool the skin. The cooling component 2 includes several telescopic condenser tubes 201. Each telescopic condenser tube 201 is rotatably mounted with an arc-shaped blood-absorbing plate 204. Each telescopic condenser tube 201 is fixedly connected to a flexible rod 205. A rotating wheel 207 is fixedly connected to the flexible rod 205. Several U-shaped frames 206 are fixedly connected at equal intervals around the hollow circular frame 102. The rotating wheel 207 is rotatably connected to the inner wall of the U-shaped frame 206. When the radiofrequency needle 101 is inserted into the human body and ablation occurs, a large amount of temperature is generated. At this time, the rotating wheel 207 and the flexible rod 205 are flipped, so that the telescopic condenser tubes 201 and the arc-shaped blood-absorbing plate 204 are flipped to the insertion position. At this time, the six arc-shaped blood-absorbing plates 204 are rotated and adjusted to form a ring shape, covering the insertion position, thereby cooling and stopping the bleeding at the wound.

[0059] Furthermore, such as Figure 10As shown, a ring 203 is fixedly connected to the U-shaped frame 206. A circular through groove is provided between the ring 203 and the U-shaped frame 206. The telescopic condenser tube 201 passes through the circular through groove, which facilitates the placement of the telescopic condenser tube 201 and prevents it from falling off when not in use.

[0060] Furthermore, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, each telescopic cooling tube 201 is fitted with a spring 202. One end of the spring 202 is fixedly connected to the arc-shaped blood-absorbing plate 204. When the telescopic cooling tube 201 and the arc-shaped blood-absorbing plate 204 cover the wound, the spring 202 can compress the wound. At the same time, when the patient moves around wildly and the radiofrequency needle 101 falls, the telescopic cooling tube 201 can wrap the needle body and needle tip of the radiofrequency needle 101 to prevent it from hitting the ground when it falls, and at the same time, it will not damage the needle body and needle tip.

[0061] Furthermore, such as Figure 1 , Figure 2 , Figure 9 As shown, several U-shaped condenser tubes 208 are fixedly connected at equal intervals on the arc-shaped blood-absorbing plate 204. Each U-shaped condenser tube 208 is fixedly connected to the telescopic condenser tube 201. The U-shaped condenser tube 208 contacts the skin, resulting in a wider contact area and minimizing the risk of burns to the skin during the ablation process.

[0062] Example 4

[0063] Please refer to Figure 1 , Figure 2 , Figure 9 The hollow circular frame 102 has a circular through slot at the lower end, through which the radio frequency needle 101 passes. The radio frequency needle 101 is fixedly connected to the circular push block 103, which allows the circular push block 103 to push the radio frequency needle 101.

[0064] The usage process of the radiofrequency ablation fixation device based on information data provided by this invention is as follows:

[0065] After the radiofrequency needle 101 is inserted into the human body, the first telescopic rod 303 and the second telescopic rod 310 of each set can be used freely. When on the arm or thigh, the fixing rod 301 rotatably mounted on the first telescopic rod 303 and the second telescopic rod 310 is adjusted 180 degrees, and then rotated in the annular groove 304 to make them face each other. At this time, the tough elastic rope 302 rotatably mounted in the middle of the fixing rod 301 can contract and tighten the sides of the arm or thigh, thereby effectively fixing it. When it is necessary to fix a larger part of the body, this method can be used. The fixing rod 301, the first telescopic rod 303, and the second telescopic rod 310 can be adjusted on both sides. Then, the human body part is inserted through the gap left between the first telescopic rod 303 and the second telescopic rod 310 and then fixed. At the same time, when fixing special parts of the human body, it is not possible to fix them by means of the device. In this case, the fixing rod 301 on the first telescopic rod 303 and the second telescopic rod 310 is rotated 90 degrees and made parallel. At this time, the fixing rod 301 is held by hand, thus forming a handle for medical personnel to hold and fix.

[0066] After the radiofrequency needle 101 is inserted into the human body, it is necessary to perform ablation and heating treatment on the liver cancer site. At this time, the temperature may burn the skin. The telescopic cooling tube 201, mounted on the hollow circular frame 102, is flipped onto the human tissue where the radiofrequency needle 101 is inserted via the flexible rod 205, the rotating wheel 207, and the U-shaped frame 206. The arc-shaped blood-absorbing plate 204, which is rotatably mounted on the telescopic cooling tube 201, rotates after flipping to form a ring, covering the insertion site. Then, the U-shaped cooling tube 208 on the arc-shaped blood-absorbing plate 204... The system cools the skin to prevent burns. At the same time, the spring 202 attached to the telescopic cooling tube 201 squeezes the arc-shaped blood-absorbing plate 204, which can compress the skin to prevent excessive bleeding during insertion. Also, when the patient moves around wildly, the spring 202 loses its resistance after the radiofrequency needle 101 is removed from the body and will move forward, thus wrapping the radiofrequency needle 101 and preventing the needle tip or body from deforming when the radiofrequency needle 101 touches the ground.

[0067] When the radiofrequency needle 101 is inserted into the human body via the handle formed by the first telescopic rod 303, the second telescopic rod 310, and the fixed rod 301, the lesion location may still require a relatively precise distance. At this time, the fixed rod 301 is squeezed by hand, and the first gear 306, which is rotatably connected to the inner wall of the first telescopic rod 303, will mesh and rotate with the first annular ring 403. The outer rings of the first annular ring 403 and the second annular ring 404 that contact the gear have tooth grooves, but the inner rings are threaded. Then the first annular ring 403 will contact the first toothed round rod 401 and rotate. 3. The first and second toothed rods 401 and 402 are not in contact. At the same time, the second gear 309, which is rotatably connected to the lower end of the second telescopic rod 310, meshes with the second ring 404. The second ring 404 is in contact with the second toothed rod 402, but not with the first toothed rod 401. In this way, the first and second toothed rods 401 and 402 rotate and move downward under the drive, thereby squeezing the circular push block 103 in the hollow circular frame 102 to push the radiofrequency needle 101 to slowly and accurately reach the lesion.

[0068] Simultaneously, to accurately determine the distance at which the radiofrequency needle 101 is inserted into the human body, a straight groove block 305 needs to be rotatably connected within the straight groove on the annular through groove 304. Both the first telescopic rod 303 and the second telescopic rod 310 are equipped with compression straight groove blocks 308. When the compression straight groove blocks 308 contact the inner wall of the annular through groove 304, the compression will not affect the movement of the first telescopic rod 303 and the second telescopic rod 310 within the annular through groove 304. When holding the rod, the movement distance of the first telescopic rod 303 and the second telescopic rod 310 should be observed. The straight groove block 305... When the first telescopic rod 303 or the second telescopic rod 310 moves to the corresponding straight groove block 305, the person flips the straight groove block 305 up to create space. At this time, when the compression straight groove block 308 on the first telescopic rod 303 or the second telescopic rod 310 is no longer squeezed, it will fill the straight groove. At this time, it is known that the radiofrequency needle 101 has reached the precise position.
