Sternal Saw
A sternal saw is a bone cutter used to perform median sternotomy, opening the patient's chest by splitting the breastbone, or sternum. It is a reciprocating blade saw that resembles a jigsaw in appearance. It was invented and introduced by Dr. Edward P.

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] |
Median Sternotomy
Median sternotomy is a type of surgical procedure in which a vertical inline incision is made along the sternum, after which the sternum itself is divided using a sternal saw. This procedure provides access to the heart and lungs for surgical procedures such as heart transplant, lung transplant, corrective surgery for congenital heart defects, or coronary artery bypass surgery Coronary artery bypass surgery, also known as coronary artery bypass graft (CABG, pronounced "cabbage") is a surgical procedure to treat coronary artery disease (CAD), the buildup of plaques in the arteries of the heart.

Human Sternum
The sternum or breastbone is a long flat bone located in the central part of the chest. It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury. Shaped roughly like a necktie, it is one of the largest and longest flat bones of the body. Its three regions are the manubrium, the body, and the xiphoid process. The word "sternum" originates from the Ancient Greek στέρνον (stérnon), meaning "chest". Structure The sternum is a narrow, flat bone, forming the middle portion of the front of the chest. The top of the sternum supports the clavicles (collarbones) and its edges join with the costal cartilages of the first two pairs of ribs. The inner surface of the sternum is also the attachment of the sternopericardial ligaments. Its top is also connected to the sternocleidomastoid muscle. The sternum consists of three main parts, listed from the top: * Manubrium * Body (gladiolus) * X ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jigsaw (power Tool)
A jigsaw is a saw which uses a reciprocating saw, reciprocating blade to cut irregular curves, such as stenciled designs, in wood, metal, or other materials. Jigsaws first emerged in the 19th century and employed a treadle to operate the blade, which was thin and under tension, being secured at both ends to an oscillating frame. This kind of saw is now usually called called a scroll saw. The modern portable jigsaw, with a rigid blade secured at one end, was introduced in 1947 by Scintilla AG (later acquired by Robert Bosch GmbH, Bosch), A jigsaw power tool is made up of an electric motor and a reciprocating saw blade. Jigsaws with sole plates that have a beveling function can cut angles typically up to 45 degrees relative to the normal vertical stroke to make miter joints. Portable jigsaws have historically been mains-powered, but are increasingly being displaced by battery-powered models.

Instruments Used In General Surgery
There are many different surgical specialties, some of which require very specific kinds of surgical instruments to perform. General surgery is a specialty focused on the abdominal contents, as well as the thyroid gland, and diseases involving skin, breasts, various soft tissues, trauma, peripheral vascular disease, hernias, and endoscopic procedures. This page is dedicated specifically to listing surgical instruments used in general surgery. Instruments can be classified in many ways - but broadly speaking, there are five kinds of instruments. # Cutting and dissecting instruments: #*Scalpels, scissors, and saws are the most traditional #*Elevators can be both cutting and lifting/retracting #*Although the term dissection is broad, energy devices such as diathermy/cautery are often used as more modern alternatives. # Grasping or holding instruments: #*Classically this included forceps and clamps predominantly #*Roughly, forceps can be divided into traumatic (tissue crushin ...

Saws
A saw is a tool consisting of a tough blade, wire, or chain with a hard toothed edge. It is used to cut through material, very often wood, though sometimes metal or stone. The cut is made by placing the toothed edge against the material and moving it forcefully forth and less vigorously back or continuously forward. This force may be applied by hand, or powered by steam, water, electricity or other power source. An abrasive saw has a powered circular blade designed to cut through metal or ceramic. Terminology * Abrasive saw: A saw that cuts with an abrasive disc or band, rather than a toothed blade. * Back: the edge opposite the toothed edge. * Fleam: The angle of the faces of the teeth relative to a line perpendicular to the face of the saw. * Gullet: The valley between the points of the teeth. * Heel: The end closest to the handle. * Kerf: The narrow channel left behind by the saw and (relatedly) the measure of its width. The kerf depends on several factors: the width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
