Developing Surgical Tools for Snaking Through The Body

Developing Surgical Tools for Snaking Through The Body | Biomimicry | Scoop.it

"A good deal of work is being done to improve how existing surgical procedures are performed by making rigid tools flexible and steerable. [...] One of the teams at TU Delft developed an arthroscopy tool that has a snake-like tip capable of bending in surprising ways. The so-called MultiFlex is an example of the bio-inspired approach that is at the heart of many of the tools being built at TU Delft. It takes ideas from octopus tentacles that have a bunch of muscle rods near the perimeter that work together to flex the tentacle well enough to be featured in horror movies."

'Octopus Tentacles' Make Future Operations More Flexible

'Octopus Tentacles' Make Future Operations More Flexible | Biomimicry | Scoop.it

"The rigidity of current surgical instruments means it is sometimes only possible to remove part of a brain tumour. Limitations such as these led Professor Paul Breedveld to develop a fundamentally new class of flexible surgical instruments, inspired by the anatomy of octopus tentacles.  [...] The tentacles of an octopus are made up of an ingenious composition of muscles which work together in various layers, rings, bundles and packages. Breedveld's early instruments were based on a single ring of steel cables surrounded by coiled springs, whereas the new instruments are based on a so-called dendritic mechanism, with branched extensions. They consist of a flexible stem which ends in a number of manoeuvrable arms. Each arm is made up of a densely structured package of flexible steering elements. The instruments also possess shape memory, therefore they 'know' where we have been."

Robotic Arm Inspired by Octopus Tentacles Aimed at Helping Surgeons

Robotic Arm Inspired by Octopus Tentacles Aimed at Helping Surgeons | Biomimicry | Scoop.it

"Surgeries might be easier and safer due to a new invention by researchers from the Sant'Anna School of Advanced Studies in Italy, a robotic arm that was inspired by tentacles of an octopus. 

The robotic arm device moves by using its inflatable chambers, imitating the natural motion of an octopus twisting and elongating its tentacles in any direction it desires."
