Circuits used to measure biological signals such as electrical activity of the heart and brain generally incorporate op-amps as a means of amplifying the relatively minuscule signals for signal processing and data analysis. [30] A commonly used amplifier is the instrumentation amplifier.
sharp cutting instruments Toothed forceps: for tearing or holding structures Mallet: used as a hammer: Skull key: a T-shaped chisel used as a lever while removing skull cap [1] Large knife: to cleanly cut the brain into anatomical sections Rib shears: to cut through the ribs while opening the chest [2] Dissecting scissors: for sharp cutting ...
Brain implants electrically stimulate, block [2] or record [3] (or both record and stimulate simultaneously [4]) signals from single neurons or groups of neurons (biological neural networks) in the brain. This can only be done where the functional associations of these neurons are approximately known.
An external ventricular drain (EVD), also known as a ventriculostomy or extraventricular drain, is a device used in neurosurgery to treat hydrocephalus and relieve elevated intracranial pressure when the normal flow of cerebrospinal fluid (CSF) inside the brain is obstructed.
Stereotactic surgery is a minimally invasive form of surgical intervention that makes use of a three-dimensional coordinate system to locate small targets inside the body and to perform on them some action such as ablation, biopsy, lesion, injection, stimulation, implantation, radiosurgery (SRS), etc.
Neuroprosthetics (also called neural prosthetics) is a discipline related to neuroscience and biomedical engineering concerned with developing neural prostheses.They are sometimes contrasted with a brain–computer interface, which connects the brain to a computer rather than a device meant to replace missing biological functionality.
Access instrument. Used to create an opening into a space without opening the abdominal cavity. A camera is inserted through one to view the interior while instruments are inserted through the others to manipulate the organs. Ultrasonic energy device Surgical device typically used to dissect tissue, but also seals small vessels and tissue bundles
