Octopod External Fixator
The Octopod Circular External Fixator is medical device developed to treat bone fractures and deformities. The device consists of 4 main vertical struts between 2 rings and 4 assistant diagonal struts. This 3rd Generation Circular External Fixator thus contains 8 combined mobile struts from which it derives its octopod name. With the octopod method the device can reach a wider correction range, thereby solving a major problem of the 2nd Generation Circular External Fixators, that of having to frequently change struts. The previous difficulties in taking manual measurements when using both 1st and the 2nd Generation External Fixators are resolved by using the 3rd Generation Circular External Fixator. Dr. Gavril A. Ilizarov developed a groundbreaking surgical technique on distraction osteogenesis in the 1950s. His technique served as the foundation for his invention, the 1st Generation Circular External Fixator. His method and the apparatus he invented are the oldest and most co ...

Medical Device
A medical device is any device intended to be used for medical purposes. Significant potential for hazards are inherent when using a device for medical purposes and thus medical devices must be proved safe and effective with reasonable assurance before regulating governments allow marketing of the device in their country. As a general rule, as the associated risk of the device increases the amount of testing required to establish safety and efficacy also increases. Further, as associated risk increases the potential benefit to the patient must also increase. Discovery of what would be considered a medical device by modern standards dates as far back as c. 7000 BC in Baluchistan where Neolithic dentists used flint-tipped drills and bowstrings. Study of archeology and Roman medical literature also indicate that many types of medical devices were in widespread use during the time of ancient Rome. In the United States it wasn't until the Federal Food, Drug, and Cosmetic Act (F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Software Technology
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taylor Spatial Frame
The Taylor Spatial Frame (TSF) is an external fixator used by paediatric and orthopaedic surgeons to treat complex fractures and bone deformity, bone deformities. The medical device shares a number of components and features of the Ilizarov apparatus. The Taylor Spatial Frame is a wikt:hexapod, hexapod device based on a Stewart platform, and was invented by orthopaedic surgeon Charles Taylor. The device consists of two or more aluminum or carbon fibre rings connected by six struts. Each strut can be independently lengthened or shortened to achieve the desired result, e.g. compression at the fracture site, lengthening, etc. Connected to a bone by tensioned wires or half pins, the attached bone can be manipulated in three dimensions and 9 degrees of freedom. Angular, translational, rotational, and length deformities can all be corrected simultaneously with the TSF. The TSF is used in both adults and children. It is used for the treatment of acute fractures, mal-unions, non-unions and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
External Fixation
External fixation is a surgical treatment wherein rods are screwed into bone and exit the body to be attached to a stabilizing structure on the outside of the body. It is an alternative to internal fixation, where the components used to provide stability are positioned entirely within the patient's body. It is used to stabilize bone and soft tissues at a distance from the operative or injury focus. They provide unobstructed access to the relevant skeletal and soft tissue structures for their initial assessment and also for secondary interventions needed to restore bony continuity and a functional soft tissue cover. Indications # Stabilization of severe open fractures # Stabilization of infected nonunions # Correction of extremity malalignments and length discrepancies # Initial stabilization of soft tissue and bony disruption in poly trauma patients (damage control orthopaedics) # Closed fracture with associated severe soft tissue injuries # Severely comminuted diaphyseal and per ...

Traumatology
In medicine, traumatology (from Greek ''trauma'', meaning injury or wound) is the study of wounds and injuries caused by accidents or violence to a person, and the surgical therapy and repair of the damage. Traumatology is a branch of medicine. It is often considered a subset of surgery and in countries without the specialty of trauma surgery it is most often a sub-specialty to orthopedic surgery. Traumatology may also be known as ''accident surgery''. Branches Branches of traumatology include medical traumatology and psychological traumatology. Medical traumatology can be defined as the study of specializing in the treatment of wounds and injuries caused by violence or general accidents. This type of traumatology focuses on the surgical procedures and future physical therapy a patients need to repair the damage and recover properly. Psychological traumatology is a type of damage to one's mind due to a distressing event. This type of trauma can also be the result of overwhelmin ...

Trauma Surgery
Trauma surgery is a surgery, surgical Specialty (medicine), specialty that utilizes both operative and non-operative management to treat traumatic injuries, typically in an acute setting. Trauma surgeons generally complete Residency (medicine), residency training in General surgery, general surgery and often fellowship training in trauma or surgical intensive-care medicine, critical care. The trauma surgeon is responsible for initially resuscitating and stabilizing and later evaluating and managing the patient. The attending trauma surgeon also leads the trauma team, which typically includes nurses and support staff as well as resident physicians in teaching hospitals. Training Most United States trauma surgeons practice in larger centers and complete a 1-2 year trauma surgery fellowship, which often includes a surgical critical care fellowship. They may therefore sit for the American Board of Surgery (ABS) certifying examination in Surgical Critical Care. National surgical ...

Bone Fracture
A bone fracture (abbreviated FRX or Fx, Fx, or #) is a medical condition in which there is a partial or complete break in the continuity of any bone in the body. In more severe cases, the bone may be broken into several fragments, known as a ''comminuted fracture''. A bone fracture may be the result of high force impact or stress, or a minimal trauma injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, osteopenia, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathologic fracture. Signs and symptoms Although bone tissue contains no pain receptors, a bone fracture is painful for several reasons: * Breaking in the continuity of the periosteum, with or without similar discontinuity in endosteum, as both contain multiple pain receptors. * Edema and hematoma of nearby soft tissues caused by ruptured bone marrow evokes pressure pain. * Involuntary muscle spasms trying to hold bone fragments in place.

Distraction Osteogenesis
Distraction osteogenesis (DO), also called callus distraction, callotasis and osteodistraction, is a process used in orthopedic surgery, podiatric surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. The procedure involves cutting and slowly separating bone, allowing the bone healing process to fill in the gap. Medical uses Distraction osteogenesis (DO) is used in orthopedic surgery, and oral and maxillofacial surgery to repair skeletal deformities and in reconstructive surgery. It was originally used to treat problems like unequal leg length, but since the 1980s is most commonly used to treat issues like hemifacial microsomia, micrognathism (chin so small it causes health problems), craniofrontonasal dysplasias, craniosynostosis, as well as airway obstruction in babies caused by glossoptosis (tongue recessed too far back in the mouth) or micrognathism. In 2016, a systematic review of papers describing bone and soft tis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fixator
In the fields of histology, pathology, and cell biology, fixation is the preservation of biological tissues from decay due to autolysis or putrefaction. It terminates any ongoing biochemical reactions and may also increase the treated tissues' mechanical strength or stability. Tissue fixation is a critical step in the preparation of histological sections, its broad objective being to preserve cells and tissue components and to do this in such a way as to allow for the preparation of thin, stained sections. This allows the investigation of the tissues' structure, which is determined by the shapes and sizes of such macromolecules (in and around cells) as proteins and nucleic acids. Purposes In performing their protective role, fixatives denature proteins by coagulation, by forming additive compounds, or by a combination of coagulation and additive processes. A compound that adds chemically to macromolecules stabilizes structure most effectively if it is able to combine with parts ...

Jonah Bone Navigation Software
Jonah or Jonas, ''Yōnā'', "dove"; gr, Ἰωνᾶς ''Iōnâs''; ar, يونس ' or '; Latin: ''Ionas'' son of Amittai, is a prophet in the Hebrew Bible and the Quran, from Gath-hepher of the northern kingdom of Israel in about the 8th century BCE. Jonah is the central figure of the Book of Jonah, which details his reluctance in delivering God's judgement on the city of Nineveh. Subsequently he returns to the divine mission after he is swallowed by a large sea creature and then released. In Judaism, the story of Jonah represents the teaching of ''teshuva'', which is the ability to repent and be forgiven by God. In the New Testament, Jesus calls himself "greater than Jonah" and promises the Pharisees "the sign of Jonah", which is his resurrection. Early Christian interpreters viewed Jonah as a type for Jesus. Jonah is regarded as a prophet in Islam, and the biblical narrative of Jonah is repeated in the Quran. Mainstream Bible scholars generally regard the Book of Jonah as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Adam Frame External Fixator
Adam; el, Ἀδάμ, Adám; la, Adam is the name given in Genesis 1-5 to the first human. Beyond its use as the name of the first man, ''adam'' is also used in the Bible as a pronoun, individually as "a human" and in a collective sense as "mankind". tells of God's creation of the world and its creatures, including ''adam'', meaning humankind; in God forms "Adam", this time meaning a single male human, out of "the dust of the ground", places him in the Garden of Eden, and forms a woman, Eve, as his helpmate; in Adam and Eve eat the fruit of the tree of knowledge and God condemns Adam to labour on the earth for his food and to return to it on his death; deals with the birth of Adam's sons, and lists his descendants from Seth to Noah. The Genesis creation myth was adopted by both Christianity and Islam, and the name of Adam accordingly appears in the Christian scriptures and in the Quran. He also features in subsequent folkloric and mystical elaborations in later Judaism, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
