Mayo scissors are a type of surgical scissor, often used in the cutting of fascia. [1]
Mayo scissors were developed by Mayo Clinic surgeons.
Mayo scissors may be made from stainless steel or titanium, with stainless steel ones being markedly cheaper than titanium ones. They may also be available in standard or extra-long scissors, and typically measure between 6 inches (150 mm) and 6 ¾ inches (170 mm) in length. [2]
Like most other modern-day surgical instruments, a vast majority of Mayo scissors are made from stainless steel and are disposable due to convenience, as such scissors do not need to be sterilized and reprocessed.[ citation needed ]
Straight- and curved-blade varieties of Mayo scissors exist, each of which is particularly suited to specific surgical, including veterinary and podiatric surgery applications.[ citation needed ]
Scissors are hand-operated shearing tools. A pair of scissors consists of a pair of metal blades pivoted so that the sharpened edges slide against each other when the handles (bows) opposite to the pivot are closed. Scissors are used for cutting various thin materials, such as paper, cardboard, metal foil, cloth, rope, and wire. A large variety of scissors and shears all exist for specialized purposes. Hair-cutting shears and kitchen shears are functionally equivalent to scissors, but the larger implements tend to be called shears. Hair-cutting shears have specific blade angles ideal for cutting hair. Using the incorrect type of scissors to cut hair will result in increased damage or split ends, or both, by breaking the hair. Kitchen shears, also known as kitchen scissors, are intended for cutting and trimming foods such as meats.
A scalpel, or lancet, or bistoury, is a small and extremely sharp bladed instrument used for surgery, anatomical dissection, podiatry and various arts and crafts. Scalpels may be single-use disposable or re-usable. Re-usable scalpels can have permanently attached blades that can be sharpened or, more commonly, removable single-use blades. Disposable scalpels usually have a plastic handle with an extensible blade and are used once, then the entire instrument is discarded. Scalpel blades are usually individually packed in sterile pouches but are also offered non-sterile. Double-edged scalpels are referred to as "lancets".
Rhinoplasty, commonly known as a nose job, is a plastic surgery procedure for altering and reconstructing the nose. There are two types of plastic surgery used – reconstructive surgery that restores the form and functions of the nose and cosmetic surgery that changes the appearance of the nose. Reconstructive surgery seeks to resolve nasal injuries caused by various traumas including blunt, and penetrating trauma and trauma caused by blast injury. Reconstructive surgery also treats birth defects, breathing problems, and failed primary rhinoplasties. Rhinoplasty may remove a bump, narrow nostril width, change the angle between the nose and the mouth, or address injuries, birth defects, or other problems that affect breathing, such as a deviated nasal septum or a sinus condition.
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 need 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.
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.
A kitchen knife is any knife that is intended to be used in food preparation. While much of this work can be accomplished with a few general-purpose knives – notably a large chef's knife, a tough cleaver, a small paring knife and some sort of serrated blade – there are also many specialized knives that are designed for specific tasks. Kitchen knives can be made from several different materials.
In cooking, a chef's knife, also known as a cook's knife, is a cutting tool used in food preparation. The chef's knife was originally designed primarily to slice and disjoint large cuts of beef. Today it is the primary general-utility knife for most western cooks.
A retractor is a surgical instrument used to separate the edges of a surgical incision or wound, or to hold back underlying organs and tissues so that body parts under the incision may be accessed. The general term retractor usually describes a simple handheld steel tool possessing a curved, hooked, or angled blade and fitted with a comfortable handle, that when in place maintains the desired position of a given region of tissue. 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 by 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 with which surgeons may forcefully drive tissues apart to obtain exposure. For specialized situations such as spinal surgery, retractors have been fitted both with suction and with fiberoptic lights to keep a surgical wound dry and illuminated.
An umbilical hernia is a health condition where the abdominal wall behind the navel is damaged. It may cause the navel to bulge outwards—the bulge consisting of abdominal fat from the greater omentum or occasionally parts of the small intestine. The bulge can often be pressed back through the hole in the abdominal wall, and may "pop out" when coughing or otherwise acting to increase intra-abdominal pressure. Treatment is surgical, and surgery may be performed for cosmetic as well as health-related reasons.
Snips, also known as shears, are hand tools used to cut sheet metal and other tough webs. There are two broad categories: tinner's snips, which are similar to common scissors, and compound-action snips, which use a compound leverage handle system to increase the mechanical advantage.
Surgical instruments can vary widely by the field of surgery that they are used in. In general instruments can be divided into five classes by function:
Pruning shears, also called hand pruners, or secateurs, are a type of scissors for use on plants. They are strong enough to prune hard branches of trees and shrubs, sometimes up to two centimetres thick. They are used in gardening, arboriculture, plant nursery works, farming, flower arranging, and nature conservation, where fine-scale habitat management is required.
Metzenbaum scissors are surgical scissors designed for cutting delicate tissue and blunt dissection. The scissors come in variable lengths and have a relatively long shank-to-blade ratio. They are constructed of stainless steel and may have tungsten carbide cutting surface inserts. The blades can be curved or straight, and the tips are usually blunt. This is the most common type of scissors used in organ-related operations.
Surgical staples are specialized staples used in surgery in place of sutures to close skin wounds or connect or remove parts of the bowels or lungs. The use of staples over sutures reduces the local inflammatory response, width of the wound, and time it takes to close.
Surgical suture is a medical device used to hold body tissues together after an injury or surgery. Application generally involves using a needle with an attached length of thread. A number of different shapes, sizes, and thread materials have been developed over its millennia of history. Surgeons, physicians, dentists, podiatrists, eye doctors, registered nurses and other trained nursing personnel, medics, clinical pharmacists and veterinarians typically engage in suturing. Surgical knots are used to secure the sutures.
Bandage scissors, or bandage forceps, are scissors that often have an angled tip with a blunt tip on the bottom blade. This helps in cutting bandages without gouging the skin. Lister bandage scissors and utility bandage scissors exhibit the well known angle, while Knowles bandage scissors have blades that are either straight or curved.
Urethrostomy is a surgical procedure that creates a permanent opening in the urethra, commonly to remove obstructions to urine flow. The procedure is most often performed in male cats, where the opening is made in the perineum.
Endodontic files and reamers are surgical instruments used by dentists when performing root canal treatment. These tools are used to clean and shape the root canal, with the concept being to perform complete chemomechanical debridement of the root canal to the length of the apical foramen. Preparing the canal in this way facilitates the chemical disinfection to a satisfactory length but also provides a shape conducive to obturation.
Surgical scissors are surgical instruments usually used for cutting. They include bandage scissors, dissecting scissors, iris scissors, operating scissors, stitch scissors, tenotomy scissors, Metzenbaum scissors, plastic surgery scissors and Mayo scissors. Surgical scissors are usually made of stainless steel. Some scissors have tungsten carbide reinforcements along their cutting edges. The hardness of this material allows the manufacturers to create sharper edges, which allows for easier and smoother cuts and keeps the scissors sharp longer.
Iris scissors are a type of scissors with short blades that was originally developed for ophthalmic surgery. They are alternatively referred to as Iris forceps in the United Kingdom and Asia. Iris scissors are also available in the crafting market and are sometimes used for the production of fabric-related goods. Both closed and open shank versions are available.
