Description

Technical Field

[0001] The invention belongs to the technical field of medical device processing, and in particular relates to a polishing device for medical device parts. Background Art

[0002] Medical device components are functional units that constitute diagnostic, therapeutic and implantable devices, including titanium alloy bone screws, cobalt-chromium stents, PEEK dental abutments, stainless steel puncture needles, microfluidic chips, etc. They are characterized by millimeter-level dimensions, micrometer-level wall thickness, and surface roughness Ra≤0.1 μm. They need to be corrosion-resistant, biocompatible, and meet ISO 13485 cleanliness standards. The difficulty in processing lies in the multiple precise microstructures, high material hardness, and complex surfaces. Traditional polishing can easily introduce scratches and residual particles, leading to cytotoxicity or thrombosis.

[0003] Therefore, polishing devices for medical device parts often use magnetic polishing machines. However, during the use of the magnetic polishing machine, the high-speed rotating stainless steel needles and medical device parts continuously impact the polishing pool, causing the polishing pool to vibrate, which in turn causes the polishing pool to tip over. After cleaning, the stainless steel needles inside the polishing pool are difficult to recover, and manual salvage is usually used, which is not only inefficient but also easy to cause harm to the operator. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a polishing device for medical device parts.

[0005] The technical solution adopted to solve the above technical problems is: a polishing device for medical device parts, including a base, the four corners of the base are fixedly connected to a fixing component, the top of the base is slidably connected to a polishing pool, the four corners of the polishing pool are installed with opening and closing pipes, the middle part of the inner side of the base is slidably connected to a disk component, and the two inner surfaces of the base are installed with lifting components.

[0006] Furthermore, the base includes a bottom box, and the four corners of the bottom box are provided with notches, and the inner walls of the notches are fixedly connected to the fixing assembly.

[0007] Furthermore, an electric guide rail groove is fixedly connected to the middle of the inner side of the bottom box, a plurality of limit blocks are fixedly connected to the inner side of the electric guide rail groove, and the inner side of the electric guide rail groove is slidably connected to the disk assembly.

[0008] Through the above technical solution, the setting of the electric guide groove not only provides a stable sliding track for the disk assembly, but also ensures the accuracy and stability of the disk assembly during movement. The design of the limit block further enhances the positioning effect of the disk assembly during the sliding process, preventing it from being offset due to external force, thereby ensuring the accuracy and reliability of the polishing operation. As the core component of the polishing device, the stable operation of the disk assembly is the key to ensuring the polishing quality.

[0009] Furthermore, a plurality of limit plates are fixedly connected to the inner wall of the bottom box, and two limit plates are slidably connected to the lifting assembly.

[0011] Through the above technical solution, the design of the fixed assembly not only enhances the connection stability between the base and the polishing pool, but also, through the cooperation of the first and second rotating shafts, enables a certain degree of flexible rotation and adjustment of the polishing pool, facilitating the adaptation to the polishing requirements of medical device parts of different shapes and sizes. The first rotating shaft, as the main rotation support point, can withstand large torques and ensure the stability of the polishing pool during rotation. The second rotating shaft, as an auxiliary rotation point, further enhances the flexibility and stability of the polishing pool. At the same time, the through-hole design of the support column not only provides solid support for the triangular block, but also ensures a secure connection between the entire fixed assembly and the base box.

This clamping method is not only flexible, but also can be adjusted according to the actual size and shape of medical device parts, ensuring stability and accuracy during the polishing process. At the same time, the middle part of the threaded rod is located at the positioning screws threadedly connected on both sides of the U-shaped plate. Through the sliding fit with the U-shaped plate, the fixing effect of the splint is further enhanced, and the loosening or displacement of the splint caused by vibration or external force during the polishing process is prevented.

[0015] Through the above technical solution, the design of the main pressure plate enables the polishing device to more flexibly adapt to medical device parts of different sizes and shapes. The main pressure plate is rotatably connected to the end of the U-shaped plate away from the first rotating shaft, thereby achieving reliable support for the polishing pool. At the same time, the main pressure plate is rotatably connected to the connecting plates on both sides of the end away from the U-shaped plate, and the second rotating shaft is rotatably connected to the end of the connecting plate away from the main pressure plate, together forming a stable pressing structure.

The motor is installed on the inner side of the mounting frame and is slidably connected to the mounting frame through the power output end. This design enables the driving force of the motor to be stably transmitted to the extended support frame. The turntable fixedly connected to the top of the extended support frame and the several permanent magnet blocks arranged in a cross on the turntable together constitute a powerful magnetic system. This magnetic system not only enhances the adsorption ability of the polishing device on the stainless steel needle, but also improves the uniformity and efficiency of polishing.

This connection method not only ensures the firmness of the motor on the mounting frame, but also facilitates the disassembly and maintenance of the motor. The use of fixing bolts makes the installation and disassembly process of the motor simpler and faster, and improves the overall maintainability and flexibility of the polishing device.

The two sides of the bottom end of the push plate are respectively fixedly connected to limit rods, and the two limit rods are respectively slidably connected to the limit plates.

[0021] Through the above technical solution, the electric push rod provides a power source for the lifting assembly, which is fixedly connected to the inner wall of the bottom box, ensuring the stability and reliability of the lifting assembly. The telescopic end at the top of the electric push rod is fixedly connected to the push plate. When the electric push rod is working, the telescopic movement of the telescopic end will be directly transmitted to the push plate, thereby realizing the up and down movement of the push plate. The top of the push plate fits with the bottom end of the polishing pool. This design enables the push plate to steadily hold up the polishing pool during the rising process, avoiding shaking or tilting of the polishing pool during movement. At the same time, the limit rods fixedly connected on both sides of the bottom end of the push plate are slidably connected to the limit plate. Such a limit structure does not It only limits the moving trajectory of the push plate to prevent it from deviating from the predetermined path during the rising or falling process, and also enhances the stability of the push plate, making it more stable and reliable during movement. Through the above technical solution, the lifting component can achieve rapid and stable lifting of the polishing pool, which is convenient for cleaning and polishing of medical device parts in the polishing pool, and improves the operational convenience and work efficiency of the polishing device. At the same time, the disk assembly can achieve "high position-middle position-low position" three-speed positioning through the lifting component, corresponding to the three process requirements of rough polishing (high position, strong magnetic force), fine polishing (middle position, medium magnetic force), and finishing (low position, weak magnetic force).

The design of the sealing cover effectively prevents the leakage of liquid at the connection between the guide tube and the polishing pool, thereby enhancing the sealing and safety of the polishing pool. The through-sliding connection between the convex plates on both sides of the sealing cover and the top of the guide tube not only realizes the stable installation of the sealing cover, but also facilitates the disassembly and cleaning of the sealing cover, thereby improving the maintainability of the polishing device.

[0024] Furthermore, the collection component includes a confluence pipe, the two openings at the top of the confluence pipe are respectively connected to the two guide pipes, the bottom end of the confluence pipe is provided with a water outlet, the water outlet is fixedly connected to the bottom box, a splash guard is installed on one side of the middle of the confluence pipe, the middle of the inner side of the confluence pipe is fixedly connected to a water guide plate, the connection between the confluence pipe and the splash guard is rotatably connected with a magnetic roller, the through-end of the magnetic roller is rotatably connected with an electric motor, the power output end of the electric motor is fixedly connected to the magnetic roller, the electric motor is fixedly connected to the confluence pipe, the bottom end of the inner side of the splash guard is fixedly connected with a scraper, the scraper is rotatably fitted with the surface of the magnetic roller, the bottom end of the splash guard is provided with a collecting bucket, and one end of the collecting bucket is slidably connected to the bottom box.
