Hand Prosthesis

Once upon a time, in a land far, far away, lived a less than honorable ship captain who lost his hand during a sword fight with a young boy. The captain’s only option to replace his once very agile and useful hand was a simple iron hook. Although the story of Captain Hook and Peter Pan is not one based in fact, the existence of a hook-style prosthetic hand is no work of fiction. Thanks to the hard work and ingenuity of countless individuals spanning more than 2000 years, gone are the days where the well-known Captain Hook claw hand is the only hand prosthesis option.
Although select individuals continue to use a hand hook, there is a large variety in types, styles, and functions of hand prostheses commercially available on today’s market. Two of these hand prosthesis options include the i-limb Ultra and the Vanderbilt Multigrasp. One of the up-and-coming models of hand prostheses is the bebionic3 designed and produced by RSLSteeper. It is necessary to discuss information regarding the technology, biomechanical basis, functional abilities, suitable population, financial cost, metabolic cost, equipment specifications, and therapy’s role, to more fully understand this product.

bebionic3 Technology:
The bebionic3 is a type of myoelectric prosthesis. A myoelectric prosthesis is custom-made to fit and attach to the remaining limb of the user (either above the elbow or below) with maximum suspension using suction technology. Once attached, the prosthesis uses electronic sensors to detect muscle, nerve, and electromyography (EMG) activity. It then translates this m...

In this essay, the author

  • Opines that the hook-style prosthetic hand is no work of fiction. captain hook and peter pan's story is not based in fact. thanks to the hard work and ingenuity of countless individuals spanning more than 2000
  • Explains that there is a large variety of types, styles, and functions of hand prostheses available on today’s market, including the i-limb ultra and vanderbilt multigrasp.
  • Describes the bebionic3 type of myoelectric prosthesis, which is custom-made to fit and attach to the remaining limb of the user with maximum suspension using suction technology.
  • Explains that the user can control the speed and force of the limb’s movements and grip by varying his or her muscle intensity.
  • Explains that the bebionic3 hand comes out of the box ready to use with preconfigured two site myoelectric controls.
  • Explains that the bebionic3 mimics normal movement of the human hand including 14 selectable grip patterns and hand positions. the thumb may be manually positioned in either an opposed or non-opposed position.
  • Explains that different handgrips and thumb positions allow for the performance of a large variety of functional tasks.
  • Explains that the bebionic3 is a highly customizable design that can be the appropriate prosthesis choice for individuals who do not have significant cognitive impairment.
  • Estimates the cost of the bebionic3 prosthesis to be between 25000 and 35000 dollars. variability in the price estimates is largely due to optional additional features.
  • Compares the metabolic cost of the bebionic3 hand prosthesis to that of a human hand.
  • Explains that the bebionic3 may be purchased in one of two sizes, medium or large. specifications for each hand size are listed in table 1 below.
  • Describes the performance specifications of the tripod grip, based on the bebionic3 technical manual.
  • Explains the primary purpose of physical therapy appointments, which vary depending on the stage of the heeling process.
  • Opines that a pt who is specialized in hand care may assist with the operation of the hand prosthesis.
  • Opines that the bebionic3 is not the correct choice for all individuals. some people may do better with a prosthesis that is much more simplified.
  • Explains that the bebionic3 hand prosthesis is an incredible technological marvel for young and old individuals alike for the return to prior level of function in individuals with unilateral or bilateral hand amputations.
  • Opines that pts should research and understand their patients' equipment so that they can help them to the greatest degree. the functional capacity of prosthetic hands has developed dramatically since the development of the first hand prosthesis.
  • Opines that silvestro micera, phd, arts lab, scuola superiore sant’anna, pontedera (pi), italy, is .
