Prosthetic limb

Types of prosthetic limb

• Bionic prosthetic limbs

  Bionic prosthetic limbs are advanced artificial limbs integrating electronic components to enable controlled movement. These limbs often use sensors that react to muscle signals, allowing the user to perform actions like gripping or walking with more fluidity. Battery life and weight are crucial in the design, as users prefer lightweight options with prolonged energy capacity. The manufacturing process usually involves a combination of high-strength materials like carbon fibre with intricate electronic circuitry to form a durable and functional limb.

• Cosmetic prosthetic limbs

  Cosmetic prosthetic limbs are designed primarily for appearance rather than function. These prosthetics are often used by individuals who seek to restore the visual aspect of a lost limb. Usually made of silicone, such prosthetics are moulded to closely resemble the skin tone and features of the original limb. Such types of limbs are often created for patients who have lost limbs due to trauma, disease, or congenital conditions. The main focus is on aesthetics, and while their primary purpose is not functionality, some may offer limited assistance.

• Transradial prosthetic limb

  A transradial prosthetic limb replaces the portion of the limb below the elbow. Such a prosthetic limb is designed after amputation above or at the wrist. These devices often include a socket that fits on the residual limb, a joint, and an artificial hand or gripping device. Materials like lightweight metals and plastic composites are instrumental in the design. The construction includes a fusion of mechanical parts and, in some cases, electronic components to allow users to perform complex tasks.

• Above-knee (AK) prosthetic limb

  Above-knee or AK prosthetic limbs are for those who have undergone amputation above the knee. These prosthetic limbs incorporate a socket that covers the residual limb and a knee joint, enabling mobility. The design challenges include providing stability while allowing flexibility. The most commonly used materials are carbon fibre and lightweight metals. The manufacturing process involves creating adaptable components that provide users with varying levels of physical activity.

• Smart prosthetic limbs

  Smart prosthetic limbs are cutting-edge technology incorporated into prosthetics. Smart limbs not only allow movement but also gather information about the user's activity levels and other health parameters, which can then be analysed to improve the device's performance. Such limbs typically have sensors and microprocessors that enable them to adapt to different walking styles or terrains, making them increasingly personalised for the user. Materials again include advanced composites, with electronic components embedded within for functionality.

Material & Durability of prosthetic limb

• Cosmetic materials

  Cosmetic prosthetics are mainly prepared with high-grade, medical-based silicone rubber. The said material is used because it is a lifelike material that is easily mouldable and thus can be used to manufacture artificial limbs that resemble the original anatomy with ease. On the other hand, Colour and texture additives are mixed with silicone to achieve skin-like tones and surface textures, and this improves functionality and makes them extremely realistic. However, it's worth noting that silicone is not as durable, so users might need regular upkeep or replacements.

• Bone anchor prosthetics

  For bone anchor prosthetics, titanium is the go-to material due to its exceptional strength and biocompatibility. Since these prosthetics are anchored to the bone, the titanium component is implanted into the bone, and this causes no harmful reactions with body tissues. The enduring nature of titanium also contributes to long-term stability and reliable implant performance. Generally, these prosthetics offer the required durability to withstand everyday activities and in the long term.

• Endo prosthetic materials

  Endo prosthetics mainly utilise high-density polyethylene (HDPE) and titanium. HDPE is strong and lightweight, making it a good choice for the parts that bear the most load. On the other hand, titanium is also widely known for its strength and great affinity with bones, thus making an ideal material for fixation components. Together, these two materials ensure that the endo prosthetics are durable and can efficiently transfer loads.

• Transhumeral prosthesis

  Transhumeral prosthetics use alloys titanium and magnesium. Designers use these materials primarily for their lightweight properties to help keep the device as easy to use as possible. In addition, titanium provides unmatched strength and periodic structural elements such as magnesium that resist corrosion and ensure longevity. This combination of materials helps to support the demands of the device.

• Bone conduction prosthetics

  With bone conduction prosthetics, durable materials like titanium and ceramics are commonly implemented. Titanium is used for the bone implant part since it strongly binds to the bone and provides great support. The ceramic parts come in handy, then, as they provide a lightweight yet strong component that does not irritate the skin and gives a steady sound transmission pathway.

Commercial use of prosthetic limb

• Medical sector

  Prosthetic limbs help patients with limb loss or congenital disabilities regain mobility and improve their quality of life. There is a soaring demand for prosthetics due to an ever-increasing focus on advanced designs, such as bionic and smart limbs. This results in the rising trend towards personalised and lightweight prosthetics, which fosters innovation. Therefore, this surge in demand should, in turn, increase the revenue and market trends comprehensively over the coming years.
