When it comes to medical gadgets, miniaturization is essential. Micro coil technology has been essential in developing medical science as the number of minimally invasive operations has increased.
The micro-coil technology aids in overcoming numerous limitations, including those related to size and manufacture. Miniaturization is yet possible with proper manufacturing process management.
The function of the micro coil in the present medical device technology will be covered in this article. We’ll also talk about the difficulties encountered when producing micro coil devices and how we overcame them.
Overcoming the Manufacturing Bottlenecks with Micro Coil Technology
When employing a micro coil for manufacturing, the following issues arise:
- Coil thickness: A device’s maximum number of turns is based on the coil’s thickness. In the fabrication of micro coil devices, it frequently proves to be difficult since a higher number of turns requires a lower thickness.
- Working with thinner cables: Working with thinner wires might be difficult. Wires smaller than 9 microns can be handled easily with the correct technology. When a number of extrinsic variables inhibit the manufacture of micro coils—which are far thinner than human hair—there is cause for concern.
- It is difficult to integrate it into the overall equipment because the wires are thin in size. Traditional welding and soldering techniques won’t work since the heat will damage the material’s physical characteristics. Solutions that include adjusting temperature and pressure can assist assure effective integration through thermo-pressure bonding.
How to Understand Thermo-Pressure Bonding in Micro Coil Technology
When it comes to micro coils, thermo-pressure bonding has been quite successful in avoiding significant integration problems. The primary difficulties with using traditional approaches include:
- Thermal imperfection in the coils: The coils experience thermal defects as the temperature rises. It causes the coil’s actual shape to shift, which has unintended side effects.
- Reaction with oxygen: Compounds can arise as a result of oxidation processes. They may compromise the connection area and compromise the durability of the medical equipment.
Thermo-pressure bonding has been used to address all of these issues.
Thermo-Pressure bonding hopes to eliminate all the disadvantages mentioned above. It delivers integration with zero corrosion that is dependable and extremely robust under high temperatures and pressure.
Additionally, it lowers the cost of production, resulting in a better profit margin.
Thermo-pressure bonding has emerged as the preferred technique for commercial medical devices after extensive testing in various environments that resulted in stress and strain tests.
Applications of Micro Coil Technology in the Medical Sector
Numerous medical applications have been explored for micro coil technology. Some of them consist of:
- Sensors: Micro coil technology has seen widespread use to detect blood pressure, heart rate, and blood and respiratory parameters due to its small size.
- End Devices: These are excellent therapeutic tools for detecting heart and nerve pulses. Additionally, there is a tonne of microwave applications, which drives up demand.
- Hearing aids: You no longer have to worry about the tiny devices fitting into your ears because they are patched with a PCB and can withstand soldering.
Medical Coil Winding
When it comes to the medical sector, devices are quite important. Due to the rising need for minimally invasive surgeries, the growth of miniature devices has accelerated. The devices are now bigger and more dependable thanks to the current trend of medical coil wrapping. The increased demand across the board is frequently due to this reliability. This manufacturing uses micro coils, which are smaller than human hair. This leads to the many difficulties that technical growth helps to resolve.
Let’s talk about some of the main difficulties encountered in the production of micro coils.
Top 4 difficulties encountered in the production of micro coils
The following issues in manufacturing micro coils are very difficult:
- Metal oxides are formed during welding as a result of the metals being exposed to heat. This altered the material’s chemical properties, lowering its quality.
- Modification of a material’s internal properties: Metals like titanium and aluminum are frequently used to make micro coils. The atoms’ activation levels increased as a result of heat exposure since it enhanced their energy. As a result, the super thin wire’s physical characteristics underwent significant alterations.
- Instability of the conventional method: The conventional method of attaching the ultra-thin wires was inefficient. Durability was in doubt, thus an alternative solution was required immediately.
- Failure to be integrated into the medical equipment: Because they will be implanted inside of people, medical gadgets must be very pure. The transfer into the medical sphere was highly challenging because old procedures did not allow for pure forms of integration.
Development in the field of medical coil winding is thermo compression bonding.
To achieve simple integration between the two coils, thermo-compression bonding involves applying high temperatures and pressure to the micro coils. This has been demonstrated to be extremely dependable and more durable. Given that the coils have very small dimensions, amalgamating the two of them is never easy.
To be integrated together in this procedure, both coils must be made of the same material or thickness. The single prerequisite makes it very simple to merge the coils with one another. Numerous tiny device uses are in medicine. The tiny devices are fairly prevalent, starting with the data tracking using pacemaker and brain simulations and going up to the stent location. This technology is being given a lot of support because of this. In the coming years, non-invasive medical procedures will become increasingly important, and medical coil winding will play a significant part in that.
The Next Big Thing in Microdevices Will Be Medical Coil Winding
When it comes to tiny gadgets, medical coil winding is indispensable. Therefore, the future ought to be prepared to adopt this new technology. In the twenty-first century, non-invasive surgery is successful thanks to micro coil devices’ strong technology and good longevity.
