Rib Spreader
A rib spreader, also known as Finochietto retractor, is a type of retractor specifically designed to separate ribs in thoracic surgery. Rack-and-pinion-type stainless steel rib spreaders (with a thumb-screw to lock it in place) were an innovation introduced by French surgeon Theodore Truffier in 1914. This was modified in 1936 by Argentinian surgeon Enrique Finochietto to have fenestrated blades (blades with "windows") and a hand-cranked lever to both separate the arms in a staged fashion and lock them in place at each stop. The Burford–Finochietto rib spreader has replaceable blades. The Tuffier and especially the Burford–Finochietto (and its variants) are ubiquitous in open thoracic surgery. Recently, a new intelligent, automated rib spreader in development demonstrated results superior to the Finochietto-style retractors.

Retractor (medical)
A retractor is a surgical instrument used to separate and manipulate the edges of a surgical incision or wound, or to hold back underlying organs and tissues so that body parts underneath may be accessed. The broad term ''retractor'' typically describes a simple steel tool possessing a curved, hooked, or angled blade, which when in place helps to maintain the desired position of a given region of tissue during surgery. These simple retractors may be handheld, clamped in place, or suspended at the end of a robotic arm. Retractors can also be "self-retaining," and not need to be held once inserted, having two or more opposing blades or hooks which are separated via spring, ratchet, worm gear or other method. The term ''retractor'' is also used to describe distinct, hand-cranked devices such as rib spreaders (also known as thoracic retractors, or distractors) with which surgeons may forcefully drive tissues apart to obtain exposure. Different surgery specialties can have specific kin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thoracic Surgery
Cardiothoracic surgery is the field of medicine involved in surgical treatment of organs inside the thoracic cavity — generally treatment of conditions of the heart (heart disease), lungs (lung disease), and other pleural or mediastinal structures. In most countries, cardiothoracic surgery is further subspecialized into cardiac surgery (involving the heart and the great vessels) and thoracic surgery (involving the lungs, esophagus, thymus, etc.); the exceptions are the United States, Australia, New Zealand, the United Kingdom, and some European Union countries such as Portugal. Training A cardiac surgery residency typically comprises anywhere from four to six years (or longer) of training to become a fully qualified surgeon. Cardiac surgery training may be combined with thoracic surgery and / or vascular surgery and called cardiovascular (CV) / cardiothoracic (CT) / cardiovascular thoracic (CVT) surgery. Cardiac surgeons may enter a cardiac surgery residency directly from me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rack-and-pinion
A rack and pinion is a type of linear actuator that comprises a circular gear (the ''pinion'') engaging a linear gear (the ''rack''). Together, they convert rotational motion into linear motion. Rotating the pinion causes the rack to be driven in a line. Conversely, moving the rack linearly will cause the pinion to rotate. A rack and pinion drive can use both straight and helical gears. Though some suggest helical gears are quieter in operation, no hard evidence supports this theory. Helical racks, while being more affordable, have proven to increase side torque on the datums, increasing operating temperature leading to premature wear. Straight racks require a lower driving force and offer increased torque and speed per percentage of gear ratio which allows lower operating temperature and lessens viscal friction and energy use. The maximum force that can be transmitted in a rack and pinion mechanism is determined by the tooth pitch and the size of the pinion as well as the gear r ...

Enrique Finochietto
Enrique Finochietto (March 13, 1881 – February 17, 1948) was a distinguished Argentine academic, physician and inventor. Life and work Enrique Finochietto was born in 1881 in Buenos Aires to Ana and Tomás Finochietto. His father died during his early childhood, and he was raised mostly by his mother. He excelled in industrial design while in secondary school, and enrolled at the University of Buenos Aires in 1897.Agencia el Viglia: Enrique Finochietto Finochietto interned at the university's Clinical Hospital, becoming an assistant to a noted surgeon, Dr. . His thesis, ''El Pie-Bot Varus-Equino-Congénito'', earned him a |

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 ...

Surgical Instruments
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] |
