Surgical scissors are surgical instruments that are often used for cutting. The most common types of scissors are Bandage scissors, dissecting scissors, iris scissors, operation scissors, stitch scissors, tenotomy scissors, metzenbaum scissors, plastic surgery scissors, and Mayo scissors.
Scissors come in a variety of forms and sharpness levels. Scissor blades can be either curved or straight. Sharp edges are typically used to cut and dissect hard muscles and tissues. Scissors are composed of medical-grade stainless steel. For hardness, some scissors have tungsten carbide reinforcement along the cutting edge. The hardness allows for sharp edges and makes cutting simpler and smoother. Approximately 2000 distinct types of surgical scissors are in use. Scissors come in a variety of forms, lengths, and cutting angles.
Scissors are divided into two types: operating and dissecting. To cut soft tissue, operating or surgical scissors are employed. Their cutting blades might be straight, curved, dull, or pointed. The cutting blade’s form is determined by the type of surgery or procedure. Because dissecting scissors are more exact than operating scissors, they are used to isolate and differentiate tissues.
Types of Scissors according to it’s Ring Type
In surgery, two types of scissors are used.
- Ring scissors resemble regular utility scissors, except they include two finger loops.
- Spring forceps are small scissors that are commonly used in eye surgery or microsurgery. The handles are ended by flat springs joined by a pivot joint. By pushing the handles together, the cutting action is performed. The spring action expands the jaws as the pressure is removed.
Types of Scissors according to it’s Blades configuration
Scissors come in a variety of configurations, such as
- Blunt/blunt blades
- Blunt/sharp blades
- Sharp/sharp blades
Types of Scissors according to it’s Blades configuration Material
Surgical scissors are often made of stainless steel, zirconia ceramic, nitinol, and titanium.

Specialized Medical Scissors Types
The type of scissors used is determined by the nature of the surgery and the location of the organ to be cut.
- Metzenbaum scissors
- Mayo scissors
- Bandage Scissors
- Tenotomy scissors
- Iris scissors
Metzenbaum scissors are surgical scissors used for delicate tissue cutting and rough dissection. The scissors are available in a variety of lengths and feature a reasonably lengthy shank-to-blade ratio. They are made of stainless steel and may feature tungsten carbide inserts on the cutting surface. The blades can be straight or curved, and the points are generally blunt. This is the most popular type of scissors used in organ transplant procedures.
Metzenbaum surgical scissors are intended for delicate tissue cutting and rough dissection. For deep cuts into the flesh, these scissors have extra-long handles and short blades. Metzenbaum scissors (also known as dissecting scissors) feature blunt cutting blades, making them perfect for dissecting a wide range of tissues.
Metzenbaum scissors feature a relatively lengthy shank-to-blade ratio and available in a variety of lengths. These scissors are further classified based on their cutting edge. Metzenbaum Scissors Regular Cut have smooth cutting blades and a satin steel finish on both rings. Metzenbaum Super Cut Scissors contain one serrated cutting edge and one gold-colored thumb ring for identification. Tungsten Carbide Metzenbaum Scissors contain tungsten carbide tips on both cutting blades. One edge is smooth, while the other is finely serrated. Both thumb rings are gold color coated.
Uses of Metzenbaum Scissors:
Metzenbaum scissorsare surgical tools used to cut tissue and suture material. The lengthy handles of Metzenbaum scissors allow the surgeon to work in deep tissues without being hindered by wide-opening scissor blades. Metzenbaum scissors, like other surgical scissors, can be used to cut dressing material or bandages. They can also be used to open tissue in preparative anatomy.

Mayo scissors are available in stainless steel or titanium, with stainless steel being much less costly. They are also available in regular or extra-long lengths, commonly ranging from 6 inches (150 mm) to 6 34 inches (170 mm).
The great majority of Mayo scissors, like most other modern-day surgical equipment, are manufactured of stainless steel and are disposable for convenience; as such, scissors do not need to be sterilised or reprocessed.
Types of Mayo scissors
There are straight-bladed Mayo scissors and curved-bladed Mayo scissors, each of which is ideally suited to specialised surgical applications such as veterinary and podiatric surgery.
Mayo scissors have semi-blunt edges, which set them apart from most other surgical scissors.
Mayo scissors with straight blades are used for cutting bodily tissues at the surface of a wound. Because straight-bladed Mayo scissors are also used to cut sutures, they are also known as “suture scissors.”
Curved-bladed Mayo scissors enable for deeper penetration into wounds than straight-bladed Mayo scissors. Mayo scissor’s curved blade is used to cut dense tissues such as those present in the uterus, muscles, breast, and foot. Mayo dissection scissors are put in tissue with the tips closed. During the dissection procedure, the scissors are opened so that the points open and spread out the tissue.
Bandage scissors, also known as bandage forceps, have an angled tip on the top blade and a blunt tip on the bottom blade. This allows you to cut bandages without gouging the skin. Lister bandage scissors and utility bandage scissors feature the well-known angle, whereas Knowles bandage scissors have either straight or curved blades.
Bandage scissors are incredibly popular in any medical setting since they are designed to safely tear bandages away from the skin to allow for simple cutting. The bottom blade of the scissor is longer and may easily be inserted beneath the bandages. The scissor’s blunt tip shape prevents accidental harm while making bandage removal simple, smooth, and rapid.
Bandage scissors are commonly used for:
- To cut bandages and dressings to the appropriate size.
- To cut medical gauze using a knife.
- To cut existing bandages.
Tenotomy scissors are an unique sort of surgical scissors. Tenotomy scissors are surgical scissors that are used for delicate procedures. Depending on the situation, they might be straight or curved, blunt or sharp. This instrument can be employed in a variety of surgical specialities, including ophthalmic surgery, oral and maxillofacial surgery, and neurosurgery.
Stevens scissors are a type of tenotomy scissors.
Tenotomy scissors feature a long handle and blades that are very tiny and thin. Straight or curved standard blades are supplied. It is determined by the surgeon’s demands and preferences throughout the process. Stainless steel is widely used due to its non-rusting and long-lasting properties.
Tenotomy scissors blade tips can be blunt, sharp, or a combination of both. Blunt dissecting operations, which frequently involve mucous membranes, are performed using blunt tipped blades. Sharp-tipped dissection knives are used for more delicate dissections that need smaller, more precise cuts.
The tenotomy scissors are specifically intended to cut tissues in restricted and constricted locations. The lengthy handles allow the surgeon to maintain a firm grasp on the scissors while guiding them into narrow areas, bodily cavities, or sensitive tissues. Precision cutting of bodily tissues is possible because to the sharp, thin, and compact blades. It also enables access to and probing of small spaces.
Uses of tenotomy scissors
Tenotomy scissors are used mostly in delicate surgical operations. They’re utilised a lot in ophthalmology and neurosurgery. Precision cutting of the sensitive and fragile tissues in the eye region, as well as the little nerves, is possible because to the small and sharp blades.
Tenotomy scissors are the primary cutting instruments in surgeries involving the eyelids, lips, and even the brain. This sort of surgical scissors is also used in surgical dissections that need precision cutting and tissue transplants that require a carefully defined region.
The brain’s nerves and tissues around the eyes are extremely sensitive. Cutting through them necessitates small, precise cuts. A little injury to normally healthy neighbouring tissues might result in irreparable harm. Damage might exacerbate an existing disease or cause new health issues. Nerves and the eye are located in small, confined cavities or parts of the body, with extremely limited space for the surgeon to operate and manipulate the delicate tissues. As a result, each cut must be precisely regulated and specified. Tenotomy scissors are capable of meeting the surgical needs in these areas.
Some tenotomy scissors are designed to cut tiny bones and cartilage, such as those found in the nasal canals. Depending on where the dissection or cut is to be done, the little scissors can easily fit into the narrow nasal apertures and reach deep back into the cavities. They can be used to sever tendons as well. The muscle groups are readily introduced because to the small blades. The blades can produce a precise cut into deeper muscle sections that is tiny enough to meet the surgery’s needs.
Iris scissors are a sort of short-bladed scissors that were designed for ophthalmic surgery. However, it is Originally designed for eye surgery and other treatments, developments in technology have made the iris scissor a multi-purpose tool in the area of medicine.
Iris scissor can bean excellent instrument for suture cutting in soft and fragile tissues. In addition to suture cutting, iris scissor is used in a variety of additional surgical and particle excavating treatments on delicate tissues. For example, the removal of microscopic particles from the cornea. Another notable application of this instrument is in the treatment of necrotic tissues.
Iris scissors are extremely tiny and have a very sharp and fine tip. For specific sorts of precise operations, certain iris scissors have curved blades, while others may have straight blades.
- Iris Scissor Design
Iris scissors are sharp, fine, and durable. The hardness of the blades makes it an ideal instrument for dissection and surgery on delicate tissues. Iris scissor’s distinctive design makes it finger-friendly. Its finger holding is available in both ring and ribbon shapes, which helps to reduce fatigue and make work easier.
- Material Composition: These scissors are composed of stainless steel surgical alloys.
- Tip / Blade Style: There are two types of blades available for the iris scissor. The following blade types are listed:
- Straight blade
- Curved blade
- Blade characteristics: The blades are firm, smooth, and sharp, making the iris scissor an excellent instrument for incision of muscles and tissues.
The scissor with curved blades is intended for tissue contouring in small spaces, whereas the scissor with straight blades is intended for cuts on flat surfaces.
The iris scissors are available in sizes ranging from 4.3″ to 4.5″, depending on the length of the blades.
Surgical Scissors Maintenance and Care
Careless handling and use may cause the instrument’s surface to be damaged or dulled. Misuse of surgical instruments might also injure test subjects. The instruments should be handled individually to avoid damage. They should be placed properly in the tray and should not be jostled around while the surgical procedure is being prepared. The scissors must not be thrown or dropped. Instruments should be sterilised and autoclaved before the surgical process to guarantee the human’s safety. The scissors should not be used to cut anything other than the tissues or vessels for which they were designed. Before reusing the scissor, the blood and leftover tissue should be cleaned away. After the surgery, the scissors should be immersed in a sterile solution to kill any infectious organisms.
