Study Notes
Advances in Biomedical Engineering
- Prosthetic devices are increasingly sophisticated; they can be internal or external, aiming to replace lost functions of the neuro-skeletomotor system.
- Tissue engineering focuses on creating biological tissue or aiding in the repair and growth of existing tissues.
- Stem cell research is pivotal for potentially replacing and regenerating damaged tissues within the body.
Recent Advances in Prosthetics
- Orthopedic Prosthetics include artificial limbs designed to replace human body parts but face challenges in mimicking natural movement.
- The C-Leg is a notable example of an advanced orthopedic prosthetic, notably used by Paralympic sprinter Oscar Pistorius.
- Designing for functionality, rather than direct human mimicry, often proves more effective in prosthetic development.
Neural Prosthetics
- Neural Prosthetics such as the Luke Arm, developed by Dean Kamen, utilize myoelectric signals for operation and are in clinical trial phases.
- These devices can be powered by the human body through electrical signals from external sources or their own power supply.
- Achieving smooth motion in neural prosthetics requires stimulation via electrodes to meet a threshold frequency, especially complex for upper extremities due to fine motor control needs.
Challenges in Prosthetic Development
- The intricate strength and flexibility required for complex hand functions create significant challenges for recreating natural hand movements.
- Lower limbs typically involve simpler joint functions, making prosthetic development less complicated compared to upper limb prosthetics.
Innovations in Tissue Engineering
- Tissue engineering includes manufacturing biological tissues outside (ex vivo) or inside (in vivo) the body to facilitate repair and growth.
- Bio-artificial tissues serve as alternatives to organ transplants and assist in studying tissue behavior under laboratory conditions.
- Improved control over cell organization and regeneration enhances the potential applications of bio-artificial tissues, including joint replacements and liver cancer treatment.
