handprothese

A hand prosthesis is a device that replaces a missing or damaged hand, enhancing or restoring the ability to perform various tasks. It can be either an external device or an implantable component depending on the individual's needs and preferences.

External hand prosthetics are designed to be worn on the residual limb, which is the remaining part of the arm after an amputation. They are typically attached to a socket that is custom-made to fit the individual's limb. External hand prosthetics can be further subdivided into passive and active devices. Passive prosthetics only provide support and do not allow for movement, whereas active prosthetics, which contain a motor and sensors, enable the user to perform more complex actions such as grasping and releasing objects.

Implantable hand prosthetics are mechanisms that are surgically inserted into the body. They usually involve a neuroprosthetic implant that is connected to a peripheral nerve and stimulates the nerves responsible for hand movement, mimicking the natural processes of the brain. Implantable prosthetics often require a significant recovery period and can also involve ongoing maintenance and potential risks of tissue rejection or infection.

Hand prosthetics have contributed to significant enhancements in the quality of life for individuals suffering from traumatic injuries, birth defects, or conditions that lead to hand loss. With technological advancements, these devices have become more sophisticated and versatile, incorporating various features such as sensor integration, motorized joints, and even computer-interfacing capabilities, greatly expanding the possibilities of manual control and overall dexterity for users.
