Bone Cutter
A bone cutter is a surgical instrument used to cut or remove bones. In addition to surgery, they are also used in forensics, torture, and dismemberment. Types of medical bone cutters include: * Unpowered – Unpowered bone cutting implements include varieties of hacksaw and sabre saw. In many applications, the saw is used in specialised jigs to provide accurate, measurable cuts, e.g. in knee surgery. Specialized saws such as the Gigli saw, a cable made of sharp strands of wire, are also used in some procedures. * Reciprocating – Usually a powered rotary oscillation is applied to a specialised cutting implement to provide smooth controllable cuts into bone, for applications, from skull cutting to rib cutting. A sternal saw is a reciprocating bone cutter. * Sonic (or sound cutting) – The sonic cutter is still experimental, but its primary focus is to use high frequency, high amplitude sound to remove material (in this case bone), providing the ability to cut. Some tissue so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Surgical Instrument
A surgical instrument is a tool or device for performing specific actions or carrying out desired effects during a surgery or operation, such as modifying biological tissue, or to provide access for viewing it. Over time, many different kinds of surgical instruments and tools have been invented. Some surgical instruments are designed for general use in all sorts of surgeries, while others are designed for only certain specialties or specific procedures. Classification of surgical instruments helps surgeons to understand the functions and purposes of the instruments. With the goal of optimizing surgical results and performing more difficult operations, more instruments continue to be invented in the modern era. History Many different kinds of surgical instruments and tools have been invented and some have been repurposed as medical knowledge and surgical practices have developed. As surgery practice diversified, some tools are advanced for higher accuracy and stability while so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bone
A bone is a rigid organ that constitutes part of the skeleton in most vertebrate animals. Bones protect the various other organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility. Bones come in a variety of shapes and sizes and have complex internal and external structures. They are lightweight yet strong and hard and serve multiple functions. Bone tissue (osseous tissue), which is also called bone in the uncountable sense of that word, is hard tissue, a type of specialized connective tissue. It has a honeycomb-like matrix internally, which helps to give the bone rigidity. Bone tissue is made up of different types of bone cells. Osteoblasts and osteocytes are involved in the formation and mineralization of bone; osteoclasts are involved in the resorption of bone tissue. Modified (flattened) osteoblasts become the lining cells that form a protective layer on the bone surface. The mineralize ...

Forensics
Forensic science, also known as criminalistics, is the application of science to criminal and civil laws, mainly—on the criminal side—during criminal investigation, as governed by the legal standards of admissible evidence and criminal procedure. Forensic science is a broad field that includes; DNA analysis, fingerprint analysis, blood stain pattern analysis, firearms examination and ballistics, tool mark analysis, serology, toxicology, hair and fiber analysis, entomology, questioned documents, anthropology, odontology, pathology, epidemiology, footwear and tire tread analysis, drug chemistry, paint and glass analysis, digital audio video and photo analysis. Forensic scientists collect, preserve, and analyze scientific evidence during the course of an investigation. While some forensic scientists travel to the scene of the crime to collect the evidence themselves, others occupy a laboratory role, performing analysis on objects brought to them by other individuals. Still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Torture
Torture is the deliberate infliction of severe pain or suffering on a person for reasons such as punishment, extracting a confession, interrogation for information, or intimidating third parties. Some definitions are restricted to acts carried out by the state, but others include non-state organizations. Torture has been carried out since ancient times. In the eighteenth and nineteenth centuries, Western countries abolished the official use of torture in the judicial system, but torture continued to be used throughout the world. A variety of methods of torture are used, often in combination; the most common form of physical torture is beatings. Since the twentieth century, many torturers have preferred non-scarring or psychological methods to provide deniability. Torturers are enabled by organizations that facilitate and encourage their behavior. Most victims of torture are poor and marginalized people suspected of crimes, although torture against political prisoners o ...

Dismemberment
Dismemberment is the act of cutting, ripping, tearing, pulling, wrenching or otherwise disconnecting the limbs from a living or dead being. It has been practiced upon human beings as a form of capital punishment, especially in connection with regicide, but can occur as a result of a traumatic accident, or in connection with murder, suicide, or cannibalism. As opposed to surgical amputation of the limbs, dismemberment is often fatal. In criminology, a distinction is made between offensive dismemberment, in which dismemberment is the primary objective of the dismemberer, and defensive dismemberment, in which the motivation is to destroy evidence. In 2019, Michael H. Stone, Gary Brucato and Ann Burgess proposed formal criteria by which "dismemberment" might be systematically distinguished from the act of "mutilation", as these terms are commonly used interchangeably. They suggested that dismemberment involves "the entire removal, by any means, of a large section of the body o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hacksaw
A hacksaw is a fine-toothed saw, originally and mainly made for cutting metal. The equivalent saw for cutting wood is usually called a bow saw. Most hacksaws are hand saws with a C-shaped walking frame that holds a blade under tension. Such hacksaws have a handle, usually a pistol grip, with pins for attaching a narrow disposable blade. The frames may also be adjustable to accommodate blades of different sizes. A screw or other mechanism is used to put the thin blade under tension. On hacksaws, as with most frame saws, the blade can be mounted with the teeth facing toward or away from the handle, resulting in cutting action on either the push or pull stroke. In normal use, cutting vertically downwards with work held in a bench vise, hacksaw blades are set to be facing forwards. History While saws for cutting metal had been in use for many years, significant improvements in longevity and efficiency were made in the 1880s by Max Flower-Nash. George N. Clemson, a founde ...

Sabre Saw
The sabre saw (also saber saw) is a hand-held powered reciprocating saw. It is similar to, but larger than, a jigsaw. The sabre saw uses a toothed blade, chiefly to cut through wood and other soft materials. The lack of a large sole plate, which a jigsaw possesses, significantly reduces the controllability of the sabre saw. Commonly referred to as a sawzall or reciprocating saw.

Jig (tool)
A jig is a type of custom-made tool used to control the location and/or motion of parts or other tools. Description A jig's primary purpose is to provide repeatability, accuracy, and interchangeability in the manufacturing of products.. An example of a jig is when a key is duplicated; the original is used as a jig so the new key can have the same path as the old one. Since the advent of automation and computer numerical controlled (CNC) machines, jigs are often not required because the tool path is digitally programmed and stored in memory. Jigs may be made for reforming plastics. Jigs or templates have been known long before the industrial age. There are many types of jigs, and each one is custom-tailored to do a specific job. Drill jig A ''drill jig'' is a type of jig that expedites repetitive hole center location on multiple interchangeable parts by acting as a template to guide the twist drill or other boring device into the precise location of each intended hole cente ...

Gigli Saw
A Gigli saw is a flexible wire saw used by surgeons for bone cutting. A Gigli saw is used mainly for amputation, where the bones have to be smoothly cut at the level of amputation.Kojiro Wada, Kentaro Mori, Terushige Toyooka, Naoki Otani, Kazuya Fujii, Hideaki Ueno, Satoshi Tomura, Arata Tomiyama, Safe fronto-orbito-zygomatic osteotomy using a diamond-coated threadwire saw in orbito-zygomatic craniotomy, in Asian J Neurosurg, vol. 10, n. 3, 2015, pp. 250-252 The saw was invented by Italian obstetrician Leonardo Gigli to simplify the performance of a lateral pubiotomy in obstructed labour.
