The Hartmann alligator forceps or Hartmann foreign body forceps, named after the German physician Arthur Hartmann, [1] are medical forceps for removing foreign bodies. It is used in addition to surgery mainly in otorhinolaryngology (ENT). Their quality depends on the origin and quality of the stainless steel. Indian steel is used often for hobbyist use. FDA and CE certified instruments also veterinary instruments are normally made of Japanese or German steel.
The shaft length varies up to one meter, is predominantly 8 to 12 cm. Only the top mouth opens alligator-like. (in US therefore has the medical term "Alligator Mouth" or "Hartmann Alligator Forceps" enforced. A common name also is "Crocodile forceps" [2] ). The standard length of the muzzle from the front hinge implementation is 1.5 cm or 1 cm. Thus, the clamp is used where normal tweezers or fine instruments are struggling to grasp small objects. So you can even grasp objects in small tubes and position them precisely.
The ear clamp is used wherever problems exist with normal tweezers or fine instruments to grasp small objects. It opens only a small part of the mouth. So you can even grasp objects in small tubes and position them precisely. Ideal during soldering, when it is difficult to accurately position small components. In veterinary medicine the Hartmann, ear polypus forceps is used to remove awns or epilate hairs of dogs ears. The design reduces the natural tremor (shaking). [3]
A sextant is a doubly reflecting navigation instrument that measures the angular distance between two visible objects. The primary use of a sextant is to measure the angle between an astronomical object and the horizon for the purposes of celestial navigation.
A clamp is a fastening device used to hold or secure objects tightly together to prevent movement or separation through the application of inward pressure. In the United Kingdom the term cramp is often used instead when the tool is for temporary use for positioning components during construction and woodworking; thus a G cramp or a sash cramp but a wheel clamp or a surgical clamp.
Tracheotomy, or tracheostomy, is a surgical procedure which consists of making an incision (cut) on the anterior aspect (front) of the neck and opening a direct airway through an incision in the trachea (windpipe). The resulting stoma (hole) can serve independently as an airway or as a site for a tracheal tube or tracheostomy tube to be inserted; this tube allows a person to breathe without the use of the nose or mouth.
A hemostat is a surgical tool used in many surgical procedures to control bleeding. For this reason, it is common in the initial phases of surgery for initial incision to be lined with hemostats which close blood vessels awaiting ligation. Hemostats belong to a group of instruments that pivot where the structure of the tip determines the function.
A speculum is a medical tool for investigating body orifices, with a form dependent on the orifice for which it is designed. In old texts, the speculum may also be referred to as a diopter or dioptra. Like an endoscope, a speculum allows a view inside the body; endoscopes, however, tend to have optics while a speculum is intended for direct vision.
Forceps are a handheld, hinged instrument used for grasping and holding objects. Forceps are used when fingers are too large to grasp small objects or when many objects needed to be held at one time while the hands are used to perform a task. The term "forceps" is used almost exclusively in the fields of biology and medicine. Outside biology and medicine, people usually refer to forceps as tweezers, tongs, pliers, clips or clamps.
Tweezers are small hand tools used for grasping objects too small to be easily handled with the human fingers. Tweezers are thumb-driven forceps most likely derived from tongs used to grab or hold hot objects since the dawn of recorded history. In a scientific or medical context, they are normally referred to as just "forceps", a name that is used together with other grasping surgical instruments that resemble pliers, pincers and scissors-like clamps.
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 surgery, while others are designed for a specific procedure. Accordingly, the nomenclature of surgical instruments follows certain patterns, such as a description of the action it performs, the name of its inventor(s), or a compound scientific name related to the kind of surgery.
Hardware disease is a common term for bovine traumatic reticulopericarditis. It is usually caused by the ingestion of a sharp, metallic object. These pieces of metal settle in the reticulum and can irritate or penetrate the lining. It is most common in dairy cattle, but is occasionally seen in beef cattle. It is very rarely reported in any other ruminants. It can be difficult to conclusively diagnose, but can be prevented by the oral administration of a magnet around the time that the animal reaches the age of one year.
A foreign body (FB) is any object originating outside the body of an organism. In machinery, it can mean any unwanted intruding object.
A violin consists of a body or corpus, a neck, a finger board, a bridge, a soundpost, four strings, and various fittings. The fittings are the tuning pegs, tailpiece and tailgut, endpin, possibly one or more fine tuners on the tailpiece, and in the modern style of playing, usually a chinrest, either attached with the cup directly over the tailpiece or to the left of it. There are many variations of chinrests such as clamped to the body in the center, on either side of the tailpiece as with a Guaneri style chinrest or to the left of the tailpiece.
Endoscopic foreign body retrieval refers to the removal of ingested objects from the esophagus, stomach and duodenum by endoscopic techniques. It does not involve surgery, but rather encompasses a variety of techniques employed through the gastroscope for grasping foreign bodies, manipulating them, and removing them while protecting the esophagus and trachea. It is of particular importance with children, people with mental illness, and prison inmates as these groups have a high rate of foreign body ingestion.
Dental instruments are tools that dental professionals use to provide dental treatment. They include tools to examine, manipulate, treat, restore, and remove teeth and surrounding oral structures.
Ambulatory phlebectomy is a minisurgical treatment for superficial varicose veins and so-called side branches.
A hip piercing is a piercing in the pelvic area through the skin near the hip bone. Hip piercings are often done in couplets with one on each hip, but it is not unusual to see only one. Hips piercing are a type of surface piercing. Microdermals or skin divers can be implanted in the hip area to give a similar appearance.
Obstetrical forceps are a medical instrument used in childbirth. Their use can serve as an alternative to the ventouse method.
Bronchoscopy is an endoscopic technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy. This allows the practitioner to examine the patient's airways for abnormalities such as foreign bodies, bleeding, tumors, or inflammation. Specimens may be taken from inside the lungs. The construction of bronchoscopes ranges from rigid metal tubes with attached lighting devices to flexible optical fiber instruments with realtime video equipment.
A travelling microscope is an instrument for measuring length with a resolution typically in the order of 0.01mm. The precision is such that better-quality instruments have measuring scales made from Invar to avoid misreadings due to thermal effects. The instrument comprises a microscope mounted on two rails fixed to, or part of a very rigid bed. The position of the microscope can be varied coarsely by sliding along the rails, or finely by turning a screw. The eyepiece is fitted with fine cross-hairs to fix a precise position, which is then read off the vernier scale. Some instruments, such as that produced in the 1960s by the Precision Tool and Instrument Company of Thornton Heath, Surrey, England, also measure vertically. The purpose of the microscope is to aim at reference marks with much higher accuracy than is possible using the naked eye. It is used in laboratories to measure the refractive index of flat specimens using the geometrical concepts of ray optics. It is also used to measure very short distances precisely, for example the diameter of a capillary tube. This mechanical instrument has now largely been superseded by electronic- and optically-based measuring devices that are both very much more accurate and considerably cheaper to produce.
Frank Henderson Mayfield, was an American neurosurgeon and founder of the Mayfield Clinic and Spine Institute in Cincinnati, Ohio. A pioneer in brain and spine surgery, he invented the spring aneurysm clip and the Mayfield skull clamp. Mayfield is best known for his clinical interests in peripheral nerve and spine injuries, development of neurosurgical instruments, and medical politics.
