Dermatome (instrument)

picture info	Dermatome (instrument) A dermatome is a surgical instrument for producing thin slices of skin from a donor area, for use in skin grafts. One of its main applications is for reconstituting skin areas damaged by third degree burn (injury), burns or Physical trauma, trauma. Dermatomes can be operated either manually or electrically. The first drum dermatomes, developed in the 1930s, were manually operated. Afterwards, dermatomes which were operated by air pressure, such as the Brown dermatome, achieved higher speed and precision. Electrical dermatomes are better for cutting out thinner and longer strips of skin with a more homogeneous thickness. Free-hand knives Those are manual dermatomes and the term ''knife'' or ''scalpel'' is used to describe them. Their disadvantages are harvesting of grafts with irregular edges and grafts of variable thickness. Their operator has to be experienced in their use for optimal results. Types There are several types of dermatomes, usually named after their inventor. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Surgical Instrument A surgical instrument is a medical 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]
picture info	Skin Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition. The adjective cutaneous means "of the skin" (from Latin ''cutis'' 'skin'). In mammals, the skin is an organ of the integumentary system made up of multiple layers of ectodermal tissue and guards the underlying muscles, bones, ligaments, and internal organs. Skin of a different nature exists in amphibians, reptiles, and birds. Skin (including cutaneous and subcutaneous tissues) plays crucial roles in formation, structure, and function of extraskeletal apparatus such as horns of bovids (e.g., cattle) and rhinos, cervids' antlers, giraffids' ossicones, armadillos' osteoderm, and os penis/ os clitoris. All mammals have some hair on their skin, even marine mammals like whales, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Skin Graft Skin grafting, a type of graft (surgery), graft surgery, involves the organ transplant, transplantation of skin without a defined circulation. The transplanted biological tissue, tissue is called a skin graft. Surgeons may use skin grafting to treat: * extensive wounding or physical trauma, trauma * Burn (injury), burns * areas of extensive skin loss due to infection such as necrotizing fasciitis or purpura fulminans * specific surgeries that may require skin grafts for healing to occur – most commonly removal of skin cancers Skin grafting often takes place after serious injuries when some of the body's skin is damaged. Surgical removal (excision or debridement) of the damaged skin is followed by skin grafting. The grafting serves two purposes: reducing the course of treatment needed (and time in the hospital), and improving the function and appearance of the area of the body which receives the skin graft. There are two types of skin grafts: * Partial-thickness: The more co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Burn (injury) A burn is an injury to skin, or other tissues, caused by heat, electricity, chemicals, friction, or ionizing radiation (such as sunburn, caused by ultraviolet radiation). Most burns are due to heat from hot fluids (called scalding), solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault). Burns that affect only the superficial skin layers are known as superficial or first-degree burns. They appear red without blisters, and pain typically lasts around three days. When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. Blisters are frequently present and they are often very painful. Healing can ...

picture info	Physical Trauma Injury is physiology, physiological damage to the living tissue of any organism, whether Injury in humans, in humans, Injury in animals, in other animals, or Injury in plants, in plants. Injuries can be caused in many ways, including mechanically with penetrating trauma, penetration by sharp objects such as Tooth, teeth or blunt trauma, with blunt objects, by heat or cold, or by venoms and biotoxins. Injury prompts an Inflammation, inflammatory response in many taxa of animals; this prompts wound healing. In both plants and animals, substances are often released to help to occlude the wound, limiting loss of fluids and the entry of pathogens such as bacteria. Many organisms secrete antimicrobial chemicals which limit wound infection; in addition, animals have a variety of immune responses for the same purpose. Both plants and animals have regrowth mechanisms which may result in complete or partial healing over the injury. Cells too can Cell damage, repair damage to a certain de ...

	Mucous Membrane A mucous membrane or mucosa is a membrane that lines various cavities in the body of an organism and covers the surface of internal organs. It consists of one or more layers of epithelial cells overlying a layer of loose connective tissue. It is mostly of endodermal origin and is continuous with the skin at body openings such as the eyes, eyelids, ears, inside the nose, inside the mouth, lips, the genital areas, the urethral opening and the anus. Some mucous membranes secrete mucus, a thick protective fluid. The function of the membrane is to stop pathogens and dirt from entering the body and to prevent bodily tissues from becoming dehydrated. Structure The mucosa is composed of one or more layers of epithelial cells that secrete mucus, and an underlying lamina propria of loose connective tissue. The type of cells and type of mucus secreted vary from organ to organ and each can differ along a given tract. Mucous membranes line the digestive, respiratory and rep ...
