Surgical Scissors
Surgical scissors are scissors specially manufactured as surgical instruments, typically used for cutting sutures, dressings, and cutting and dissecting biological tissue. Surgical scissors are usually made of surgical steel. Some have tungsten carbide reinforcements along their cutting edges, the hardness of which allows manufacturers to create sharper and more durable edges. Mechanical types of scissors There are two main mechanical types of scissors used in surgery: * Ring scissors, which look and function much like standard utility scissors with ring finger loops * Spring forceps are small scissors used mostly in eye surgery or microsurgery. The handles end in flat springs connected with a pivot joint. The cutting action is achieved by pressing the handles together. As the pressure is released, the spring action opens the jaws. Scissors are available in various configurations like * Blunt/blunt blades * Blunt/sharp blades * Sharp/sharp blades Examples Some examples of su ...

Scissors
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. Inexpensive, mass-produced modern scissors are often designed ergonomically with composite thermoplastic and rubber handles. Terminology The ...

Needle Holder
A needle holder, also called needle driver or needle forceps, is a surgical instrument similar to a hemostat, used by doctors and surgeons to hold and push a suturing needle when performing wound closure, ligation and other surgical procedures that require re-anastomosis. Being specialized forceps, the components of a typical needle holder are the ''jaws'' (often reinforced with tungsten carbide inserts), the hinged ''joint'' and the ''handles'' (typically with finger rings at the end). Most needle holders also have a ratchet mechanism that locks the handles together and clamps the needle firmly between the jaws, allowing the user to maneuver the needle through various tissues without having to keep squeezing the grip. To maintain a firm grip on the needle, the jaws are often textured and short compared to the handles (increasing the mechanical advantage using the principle of a lever). Most needle holders are designed to be gripped with the fingers and palm like scissors. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hemostat
A hemostat (also called a hemostatic clamp, arterial forceps, or pean after Jules-Émile Péan) 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 the initial incision to be lined with hemostats which close blood vessels awaiting ligation. Hemostats belong to a group of instruments that pivot (similar to scissors, and including needle holders, tissue holders and various clamps) where the structure of the tip determines its function. The hemostat has handles that can be held in place by their locking mechanism. The locking mechanism is typically a series of interlocking teeth, a few on each handle, that allow the user to adjust the clamping force of the pliers. When locked together, the force between the tips is approximately 40 N (9 lbf). History The earliest known drawing of a pivoting surgical instrument dates back to 1500 BC on a tomb at Thebes, Egypt. Later Roman bronze and steel piv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trauma Shears
Trauma shears, also known as Tuff Cuts (a brand name), are a type of scissors used by paramedics and other emergency medical personnel to quickly and safely cut clothing from injured people. They usually consist of a plastic handle with a metal blade, which is traditionally bent at about 150 degrees, giving them an unusual appearance as compared to normal scissors, and also a longer "lever arm". The shears were designed exclusively for external use and are not suitable for surgical or invasive procedures. Their rugged construction enables them to cut through strong materials such as car seat belts, leather, and denim, and even thin metal and other hard surfaces. They are increasingly being used by fishermen, soldiers and scuba divers as safer alternatives to knives. Hobbiests use them to cut metals, such as small coins, and copper. The wide, blunt tip on the shears is designed to slide across skin, minimizing the risk of injuring the patient while cutting clothing. Bandage sciss ...

Mayo Scissors
Mayo scissors are a type of surgical scissor, often used in the cutting of fascia. Etymology Mayo scissors were developed by Mayo Clinic surgeons. Description 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. 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. Types of Mayo scissors Straight- and curved-blade varieties of Mayo scissors exist, each of which is particularly suited to specific surgical, including veterinary and podiatric surgery applications. *Mayo scissors have semi-blunt ends, a feature that distinguishes them from most other surgical scissors. Metzenbaum scissors are, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhytidectomy
A facelift, technically known as a rhytidectomy (from the Ancient Greek () "wrinkle", and () "excision", the surgical removal of wrinkles), is a type of cosmetic surgery procedure used to give a more youthful facial appearance. There are multiple surgical techniques and exercise routines. Surgery usually involves the removal of excess facial skin, with or without the tightening of underlying tissues, and the redraping of the skin on the patient's face and neck. Exercise routines tone underlying facial muscles without surgery. Surgical facelifts are effectively combined with eyelid surgery (blepharoplasty) and other facial procedures and are typically performed under general anesthesia or deep twilight sleep. According to the most recent American Society for Aesthetic Plastic Surgery facelifts were the third most popular aesthetic surgery in 2019, surpassed only by rhinoplasty and blepharoplasty.

Metzenbaum Scissors
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. Etymology The name Metzenbaum derives from the designer, Myron Firth Metzenbaum (1 April 1876 – 25 January 1944), an American surgeon who specialized in oral and reconstructive surgery. They are also occasionally referred to as Metzenbaum or Metzenbaum–Lahey forceps.

Surgical Instrument
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 som ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bandage Scissors
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. Bandage scissors are very popular in any health care facility A health facility is, in general, any location where healthcare is provided.
