Description

Technical Field

[0001] This invention relates to the technical field of implantable medical devices, and more particularly to a gold-labeled implant and its positioning feature processing equipment. Background Technology

[0002] Currently, cancer treatment methods include five approaches: surgery, radiotherapy, chemotherapy, traditional Chinese medicine, and immunotherapy. Radiotherapy, also known as RF, is a local treatment method that, although only a few decades old, has developed rapidly. With the help of advancements in CT imaging and computer technology, radiotherapy techniques have evolved from two-dimensional to three-dimensional and four-dimensional radiotherapy. Dosage distribution has also progressed from point dose to volumetric dose distribution, and within volumetric dose distribution, intensity-modulated radiation therapy (IMRT). For example, stereotactic radiotherapy (SRT) includes three-dimensional conformal radiotherapy (3DCRT) and three-dimensional conformal intensity-modulated radiotherapy (IMRT); stereotactic radiosurgery (SRS) includes X-knife, Gamma Knife, and CyberKnife, characterized by three-dimensional, small-field, focused, fractionated, and high-dose irradiation. With the rapid development of modern medical technology, radiotherapy has seen the emergence of new treatment methods such as proton therapy, heavy ion therapy, linear accelerators, adaptive radiotherapy, image-guided radiotherapy, and helical tomotherapy. All of these radiotherapy methods require higher localization accuracy of the lesion and faster dose attenuation outside the target area. If the location of the tumor cannot be determined on imaging, high-precision treatment cannot be performed.

[0003] Therefore, to visualize the anatomical location of a tumor, metallic markers are typically implanted in or around the tumor tissue before treatment. This allows for tracking the tumor's position during CyberKnife treatment, enabling rapid and precise treatment. However, because the metallic marker particles are small and have smooth surfaces, they are prone to slippage after implantation in the tumor tissue or surrounding specific tissues, affecting the accuracy of detection and localization.

[0039] Example 1

[0040] Reference Figure 1This first embodiment of the invention provides a gold label implant, comprising: a gold label 100, which is cylindrical and has positioning features 101 on its sidewall; the gold label 100 is made of alloy, with a diameter of 3 mm and a length of 10 mm; a drug layer is coated on the surface of the gold label 100; multiple positioning features 101 are provided and evenly distributed on the sidewall of the gold label 100; the positioning features 101 are one or more of the following shapes: herringbone, X-shape, and inverted V-shape, with each layer of positioning features 101 evenly distributed circumferentially on the sidewall of the gold label 100, and the positioning features 101 in different layers are staggered or parallel; the positioning features 101 are protrusions on the sidewall of the gold label 101; the drug layer is used for sustained-release drug delivery to tumor tissue.

[0041] The gold-labeled electrode 100 is used to locate tumors. Implanted into the tumor tissue, the gold-labeled electrode 100 blocks signals from the treatment device, allowing the device to pinpoint its location. This increases the accuracy of tumor localization, preventing damage to healthy tissues due to mis-localization and reducing side effects. Preferably, the gold-labeled electrode 100 uses an inert electrode material suitable for the body's chemical environment, ensuring long-term use without harm or interference with routine CT and X-ray examinations. The gold label 100 is cylindrical, making it easy to insert into the tumor. Positioning features 101 are located on the sidewall of the gold label 100, increasing the friction between the gold label 100 and the tumor tissue, ensuring stable attachment of the gold label 100 within the tumor tissue. Movement of the tumor tissue caused by the user's movements or jumping will not affect the positioning of the gold label 100. Positioning features 101 can be in various shapes, such as herringbone, X-shape, or indentation, effectively increasing friction and allowing for the application of therapeutic drugs for sustained-release administration. As an optional solution, multiple sets of positioning features 101 are arranged on the sidewall of the gold label 100, evenly spaced along its circumference. Multiple sets of positioning features 101 further increase the friction of the gold label 100. Each set of positioning features 101 includes two or more positioning features 101. The surface of the gold label 100 also has a drug layer for sustained-release administration to the tumor tissue, while also providing lubrication to facilitate insertion into the tumor tissue.

[0042] Example 2

[0043] Reference Figures 2-16This is a second embodiment of the present invention, which differs from the first embodiment in that it provides a positioning feature processing device, including an electrical discharge machining (EDM) machine 102 and a control component 103 disposed opposite to the EDM machine 102; the control component 103 includes a rotating assembly 200 and a power receiving assembly 300; the rotating assembly 200 includes a mounting frame 201, a motor 202 disposed on the mounting frame 201, a first bevel gear 203 connected to the motor 202, a second bevel gear 204 meshing with the first bevel gear 203, a chuck component 205 fixed to the second bevel gear 204, and a clamping component 206 disposed on the chuck component 205; the power receiving assembly 300 includes a fixed plate 301 fixed to the chuck component 205, a rotating cover 302 threadedly connected to the fixed plate 301, a pressure cover 303 slidably connected to the rotating cover 302, a limiting cylinder 304 fixedly connected to the fixed plate 301, and a conductive buckle 305 slidably connected to the limiting cylinder 304.

[0044] Furthermore, the chuck component 205 includes a drive cover 205a, a fixed disk 301 fixedly connected to the drive cover 205a, a through hole 301a in the center of the fixed disk 301, a knob 302a on the rotating cover 302, and a first hole 302b in the center of the rotating cover 302. A pressure cover 303 is fitted into the first hole 302b of the rotating cover 302, a limit ring 303a is provided at the end of the pressure cover 303, a second hole 303b is provided in the center of the pressure cover 303, and a ball bearing 303c is also provided between the limit ring 303a and the rotating cover 302. The end of the limiting cylinder 304 near the fixed plate 301 is fixedly connected to the fixed plate 301. The limiting cylinder 304 is sleeved inside the pressure cover 303, and the pressure cover 303 is slidably connected to the limiting cylinder 304. A limiting plate 304a is provided in the middle of the limiting cylinder 304, and a ball bearing 303c is provided between the limiting plate 304a and the fixed plate 301. The inner wall of the port of the limiting cylinder 304 near the pressure cover 303 is funnel-shaped, and the radial diameter of the inner wall of the limiting cylinder 304 is larger than the radial diameter of the second hole 303b. The conductive buckle 305 is made of conductive material and is slidably disposed inside the limiting cylinder 304. The end of the conductive buckle 305 has four sets of buckles 305a. The outer wall of the buckles 305a is funnel-shaped and the buckles 305a are evenly arranged in a circle. The buckles 305a are flexibly disposed at the end of the conductive buckle 305. The conductive buckle 305 is electrically connected to the mounting bracket 201 through the through hole 301a.

[0045] It should be noted that when performing electrical discharge machining on the sidewalls of the raw material alloy, the alloy wire needs to be fixed in place, and the alloy needs to be connected to the electrode. Because the alloy wire is very thin, conventional clamping methods are not suitable. Therefore, in order to clamp the alloy wire and control the rotation angle, refer to... Figure 16The fixed plate 301 is fixed to the drive cover 205a, which can be regarded as the stationary end. The alloy wire end is inserted into the buckle 305a. The rotating cover 302 can be turned by the knob 302a, so that the rotating cover 302 moves closer to the fixed plate 301. The rotating cover 302 is equipped with a ball bearing 303c and a pressure cover 303. When the rotating cover 302 moves, it will push the ball bearing 303c to move synchronously. The bottom of the ball bearing 303c is provided with a limiting ring 303a of the pressure cover 303. The ball bearing 303c will push the limiting ring 303a to move together. That is, the movement of the rotating cover 302 will cause the pressure cover 303 to be squeezed inward. When the pressure cover 303 moves, it will push the conductive buckle 305 to retract into the limiting cylinder 304. Since the buckle 305a at the end of the conductive buckle 305 is flared, The inner wall of the limiting cylinder 304 is also funnel-shaped, and the radial diameter of the inner wall of the limiting cylinder 304 is larger than the radial diameter of the second hole 303b. Therefore, the pressure cap 303 can definitely contact the conductive buckle 305 and apply force to it. When the buckle 305a moves into the limiting cylinder 304, the inner wall of the limiting cylinder 304 narrows continuously, causing the four sets of buckles 305a to tighten towards the center, clamping the alloy wire inside the conductive buckle 305. It should be noted that when the diameter of the alloy wire is in the millimeter range, it is relatively fragile and soft, with a certain degree of ductility. Therefore, this four-way clamping scheme has the best clamping effect. At the same time, it relies on manual adjustment and should not be excessively squeezed on the alloy wire to prevent deformation. After adjusting the knob 302a to the appropriate position, stop in time to prevent the buckle 305a from being over-tightened. After the conductive buckle 305 is tightened, since the conductive buckle 305 is a conductive material, while fixing the alloy wire, it also connects the alloy wire to the electrode, which can then be subjected to electrical discharge machining.

[0046] To control the rotation angle of the fixed alloy wire during processing, refer to Figures 5-15The motor 202 is fixedly mounted on the top of the mounting bracket 201, and the output shaft of the motor 202 extends into the mounting bracket 201. A first bevel gear 203 is fixed to the end of the output shaft of the motor 202. The chuck component 205 includes a drive cover 205a, a threaded ring 205b disposed in the drive cover 205a, and a handle 205c that meshes with the threaded ring 205b. The drive cover 205a is rotatably connected to the mounting bracket 201, and the bottom of the drive cover 205a is fixedly connected to the second bevel gear 204. The surface of the drive cover 205a also has an opening. Three sliding grooves 205d are evenly distributed circumferentially on the drive cover 205a; a threaded ring 205b is rotatably disposed inside the drive cover 205a, with a thread on its surface and a beveled groove at its bottom; multiple handles 205c are provided, rotatably disposed inside the drive cover 205a, with a bevel gear at the end of the handle 205c located inside the drive cover 205a, and the bevel gear on the handle 205c meshing with the beveled groove at the bottom of the threaded ring 205b. The clamping member 206 includes a movable block 206a and a clamp 206b disposed on the movable block 206a. There are three movable blocks 206a, which are slidably connected to the slide groove 205d. Each movable block 206a corresponds to each slide groove 205d. Multiple positioning points 206c are provided on the bottom of the movable block 206a. The positioning points 206c are evenly spaced and are embedded in the grooves between the threads on the surface of the threaded ring 205b. The clamp 206b is rotatably connected to the movable block 206a. One end of the clamp 206b is provided with a contact point 206d, and the other end is provided with an auxiliary clamp 206e.

[0047] After the alloy wire end is fixed, due to the alloy's ductility, it still needs auxiliary clamping. The fixed plate 301 and the drive cover 205a are fixedly connected, which can be regarded as the power connection component 300 being fixed and stationary on the rotating component 200. Turning the handle 205c can adjust the bevel gear groove at the bottom of the threaded ring 205b through the bevel gear on the handle 205c, that is, the handle 205c can drive the threaded ring 205b to rotate. Threads are provided on the surface of the threaded ring 205b. The threads can rotate clockwise or counterclockwise according to the rotation direction of the handle 205c. The slot contains a positioning point 206c for the movable block 206a. Rotation of the thread drives the positioning point 206c to move closer to or away from the thread center. Since the movable block 206a is located within the slide groove 205d, its direction of movement is fixed by the extension direction of the slide groove 205d. When the thread rotates, the positioning point 206c drives the movable block 206a closer to or away from the central electrical component 300. For example, when it moves closer, the movable block 206a moves the clamp 206b closer to the rotating cover 302 until the contact point 206d contacts the rotating cover 302. At the 02 end, the auxiliary clamp 206e abuts against the alloy wire. The clamp 206b has three clamps; the three auxiliary clamps 206e can effectively hold the alloy wire. Similarly, turning the handle 205c here is still manual operation to prevent excessive compression of the alloy wire by the auxiliary clamps 206e. After clamping and fixing, the alloy wire can be subjected to electrical discharge machining (EDM). After machining, the alloy wire needs to be rotated to machine the other side. The motor 202 can be started, and the output shaft of the motor 202 drives the first bevel gear 203 to rotate, causing the first bevel gear 203 to mesh with it. The second bevel gear 204 rotates, that is, the motor 202 can drive the drive cover 205a to rotate. The drive cover 205a carries the rotating component 200 and the electrical connection component 300, which can make the clamped alloy wire rotate with the drive cover 205a. It should be noted that the bottom of the conductive buckle 305 is electrically connected to the mounting bracket 201 through the through hole 301a. The conductive buckle 305 is in contact with the electrode end face through the conductive material. The two are not connected. Therefore, the rotation of the conductive buckle 305 will not be affected by the electrical connection of the electrodes inside the mounting bracket 201.

[0048] refer to Figures 2-16The workflow is as follows: insert both ends of the alloy wire into the conductive buckles 305 of the control components 103 on both sides, turn the knob 302a to tighten the buckle 305a to clamp the alloy wire. After the initial clamping is completed, turn the handle 205c to control the moving block 206a to move closer to the electrical assembly 300 until the contact point 206d on the clamp 206b and the auxiliary clamp 206e fix the alloy wire. At this time, the EDM loading operation is completed. Pour the medium liquid into the processing pool until the alloy wire is completely submerged in the medium liquid. Start the EDM machine 102 to process the alloy wire and strike the positioning feature 101 of the specified shape on the surface of the alloy wire. After processing on one side, start the motor 202 to drive the alloy wire to rotate and flip. Repeat the processing on the other side. After processing is completed, discharge the medium liquid and reverse the above operation to remove the alloy wire. Cut the alloy wire to obtain the processed gold mark 100.

[0049] This positioning feature processing equipment uses an electrical discharge machining (EDM) unit 102, combined with a precision control unit 103, to achieve high-precision metal processing. The core components of the equipment include a rotating assembly 200 and a power connection assembly 300. The motor 202 drives the first bevel gear 203, which in turn drives the second bevel gear 204 to rotate, causing the drive cover 205a to rotate, which can effectively control the rotation angle of the alloy wire.

[0050] The electrode connection assembly 300 uses an adjustable knob 302a to clamp the alloy wire and connect it to the electrode. The conductive buckle 305 is designed with four sets of trumpet-shaped buckles 305a, which can evenly clamp the thin alloy wire, ensuring stable and accurate force application during EDM. The pressure cap 303 pushes the conductive buckle 305 to retract, forming an effective clamp, while the limiting cylinder 304 provides structural support to avoid excessive compression during clamping, thereby protecting the integrity of the alloy wire.

[0051] During processing, after the two ends of the alloy wire are inserted into the conductive clips 305, initial and auxiliary clamping are achieved through the knob 302a and handle 205c, ensuring that the alloy wire is completely immersed in the medium liquid during processing. Through the operation of the electrical discharge machining (EDM) machine 102, precise positioning features 101 can be formed on the surface of the alloy wire. The flexible operating procedure and multiple clamping mechanisms employed in the design improve the accuracy of the positioning features 101 on the gold standard 100, which has a positive impact on tumor tissue treatment.

[0052] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
