Benefits of Advanced Plastics in the Surgical Robots Manufacturing – Earn Charter

The use of advanced plastic is a revolutionary paradigm in the manufacturing of surgical robotic structures. The advanced plastics that are mostly used in the manufacturing of surgical robots such as PEEK, Polyetherimide, PC, and ABS have excellent machining capabilities. From heightened precision to enhanced durability, the integration of advanced plastics emphasizes the critical role of plastic machining in shaping the future of surgical robotics.

These materials not only enhance the thermophysical and biocompatibility of these robots but also able the engineers to design intricate structures with a high level of precision and quality. Further in this article, we will explore how the advanced materials enhance the efficiency of these surgical robots, and discover how precise plastic machining techniques are revolutionizing the landscape of surgical robotics.

Achieving High-Strength Lightweight Joints

Designing high-strength lightweight joints is the most important parameter of designing a surgical report. The right structural stability increases the optimal performers and manoeuvrability of the robots during surgical procedures.  The advanced materials are capable of providing strength and durability in a lightweight structure which definitely reduces the overall mass of the machine and enhances its rotatory motion.

The most important material used in this parameter is carbon fiber-reinforced polymer.  The CFRP material Has excellent strength-to-weight ratio properties which make it a perfect choice for joint components. Joint components made from carbon fibers have excellent structural integrity of plastic matrix along with mechanical properties while having a minimum weight structure. The implementation of this material can be observed in the manufacturing of robotic arms that are used for invasive purposes. The arm joints which are made from CFRP material contribute in reducing the overall inertia of the robotic structure.  This reduction of inertia will be the quicker and more precise moments of the robotic arms and it is quite helpful in robots which are used in navigating the intricate anatomical structures.

However, material selection is not enough along the precision machining process is the key for the successful production of these joints.  Advanced precision machining techniques Like 3D modeling and printing along with multi-axis machinery enable the engineers to create these intricate joint geometries that optimize the overall structural integrity without compromising the inertial movement of the robots.

For instance, consider the robotic surgical system which is used in orthopedic procedures. This robotic system is constructed with the help of advanced plastics and multi-axis machinery.  The robotic system is manufactured, such that it is able to replicate the natural range of motion of human joints. Furthermore, the use of advanced plastics minimizes the impact of the weight of the robotic arm on the human body and the surrounding tissues so that it will ultimately reduce the patient’s trauma.

Machining Enclosure and Casing for Electronics

The robotic structure consists of many miniature components. A lot of small enclosures and cavities are required for the electric components and feedback system required for these robots.   adaptive feedback system along with a control unit need specific housing and pathways for wiring so that the motion delay can be minimized. Precision machining along with modern machining capabilities enables the engineers to create these intricate geometrics.

Machining in closures and casings Involves a lot of technical details so that engineers ensure optimal functionality and performance. Advanced plastics Polycarbonate or PEEK known for its high impact and transparency. It is an excellent material due to its machineability properties as it allows to creation of intricate designs that precisely tailor enclosures for electronic components. For that reason, it is used for creating housing for delicate sensor processors and creating critical paths for wiring.

Moreover, PEEK has excellent thermoplastic, biocompatibility, chemical resistance, and dimensional stability. In designing housing and casing production titanium is the second most material that is used, that’s all due to its properties of biocompatibility and machineability.

Machining for Custom End-Effector Designs

Customization is very crucial for manufacturing surgical robots. Each surgeon and patient may have some specific requirements that need to be fulfilled by customization. Precision machining along with multi-axis CNC machines sorts out this issue and enables specific geometries for surgeries and implants.

Neurosurgical procedures are the best example where customization is the most important paramount.  advanced materials such as peek and multi-axis machinery allow to design of precise robots for the manipulation of neural tissues. Applying this customization technique ultimately reduces trauma and enhances surgical outcomes.

Customization is also prominent when we talk about sensors and amazing devices in robots.  with customized sensors and improved control unit surgeons can have a quick feedback system without any delay.  similarly, lenses and cameras used with miniature components are the gift of these precise machines.

Radiolucency Material Requirements

Radiolucency In robotic parts is getting famous day by day. This property facilitates and enhances intraoperative imaging during surgeries. The materials having this property are able to allow X-rays and other diagnostic tools to pass through the robotic components so that the visibility during surgical procedures is not affected. The implementation of radiolucent properties allows surgeons to accurately monitor and access the target portion without any interference. In surgical reports components such as robotic arms casings and joint assembly are made from radiolucent plastics.

For instance, during the manufacturing of robotic arm segments, these advanced plastics having radiolucent properties are used. The transparency of the material allowed the surgeon to visualize the anatomical structures in real-time X-rays. This technique is particularly advantageous during orthopedic surgeries where surgeons have to observe all the intricate bond structures for a perfect fit.

Radiolucency in robotic equipment is valuable even in abdominal and thoracic surgeries where visible organs or the surrounding tissues are very sensitive to handle. Peek and ABS materials show this versatility they have excellent results in this property however advanced machines and molding processes are necessary to machine these materials while conserving radiolucent properties.

Robotic joints structures are mostly manufactured by these techniques, Injection molding technique is specifically used for this purpose where solidification and cooling are done precisely to gain the desired radiolucent results.

Conclusion

With modern research, a lot of advanced plastics are available in the market however their properties can only be conserved if you choose the right machining options for them.  Precision machining enables the manufacturers to design structures that have versatility in biocompatibility, structural stability and have eye catching thermophysical properties. But before that one should confirm that their machine shop has specific machining facilities to process these advanced materials.
