Cranial Drill
A cranial drill, also known as a craniotome, is a tool for drilling simple burr holes (trepanation) or for creating larger openings in the skull. This exposes the brain and allows operations like craniotomy and craniectomy to be done. The drill itself can be ''manually'' or ''electrically'' driven, and primarily consists of a handpiece and a drill bit, which is a sharp tool that has a form similar to Archimedes' screw; this instrument must be inserted into the drill chuck to perform holes and remove materials. The trepanation tool is generally equipped with a clutch which automatically disengages once it touches a softer tissue, thus preventing tears in the dura mater. For larger openings, the craniotome is an instrument that has replaced manually pulled saw wires in craniotomies from the 1980s. History Cranial drill The oldest evidence of a hole being applied on a human's brain with a drill dates from c. 4000 B.C. The oldest cranial drilling instrument was found in Franc ...

Skull
The skull, or cranium, is typically a bony enclosure around the brain of a vertebrate. In some fish, and amphibians, the skull is of cartilage. The skull is at the head end of the vertebrate. In the human, the skull comprises two prominent parts: the neurocranium and the facial skeleton, which evolved from the first pharyngeal arch. The skull forms the frontmost portion of the axial skeleton and is a product of cephalization and vesicular enlargement of the brain, with several special senses structures such as the eyes, ears, nose, tongue and, in fish, specialized tactile organs such as barbels near the mouth. The skull is composed of three types of bone: cranial bones, facial bones and ossicles, which is made up of a number of fused flat and irregular bones. The cranial bones are joined at firm fibrous junctions called sutures and contains many foramina, fossae, processes, and sinuses. In zoology, the openings in the skull are called fenestrae, the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hippocratic Corpus
The Hippocratic Corpus (Latin: ''Corpus Hippocraticum''), or Hippocratic Collection, is a collection of around 60 early Ancient Greek medical works strongly associated with the physician Hippocrates and his teachings. The Hippocratic Corpus covers many diverse aspects of medicine, from Hippocrates' medical theories to what he devised to be ethical means of medical practice, to addressing various illnesses. Even though it is considered a singular corpus that represents Hippocratic medicine, they vary (sometimes significantly) in content, age, style, methods, and views practiced; therefore, authorship is largely unknown. The ancient commentaries on this corpus, from writers such as Attalion and Oribasius, are myriad. Hippocrates began Western society's development of medicine, through a delicate blending of the art of healing and scientific observations. What Hippocrates was sharing from within his collection of works was not only how to identify symptoms of disease and proper di ...
