Scissors
Hand-held instruments designed to cut thin materials, such as paper and cloth, consisting of two blades laid one on top of the other; products may be intended for use in specific applications such as cutting tissue or bone, dissections, etc.
Scissors are used in the laboratory to cut various materials. Some are for general use and others are designed specifically for tissue dissection or surgery.
Scissors are hand-operated tools that consist of a pair of metal blades with handles. The blades pivot to bring the sharpened edges in contact with each other, an action that cuts the material placed between the blades.
Scissors are selected based on specific features:
- Size or length: Blade length is key, as is the overall length of the scissors
- Shank-to-blade ratio: The length of the handles compared to the length of the cutting blade; the ratio helps determine the force needed to product a cut
- Type of handles: Straight, offset
- Material: Stainless steel is typically used for surgical scissors; some surgical scissors also have tungsten carbide cutting surfaces for hardness and durability
- Tips: Blade ends may be pointed, semi-blunt, or blunt (rounded)
- Blade shape: Straight, curved, or angled (bent); curved or angled blades may provide better access to areas with limited space
World Precision Instrument Castroviejo Curved Scissors, 12cm, Curved, Titanium
Castroviejo titanium scissors are surgical scissors designed for precise cutting in delicate surgical procedures like ophthalmic surgery, microsurgery, microdissection, and other procedures requiring precision cutting. Titanium Castroviejo scissors are 40% lighter than the stainless-steel varieties, reducing hand fatigue. Titanium is known for its strength, corrosion resistance, and biocompatibility. It is non-magnetic, and it won’t rust. Castroviejo scissors are spring scissors with a fine and slender design, allowing for precise and controlled cutting. The blades are sharp and tapered, making them suitable for intricate tasks. These two sizes of Castroviejo titanium scissors have curved blades. One has 16 mm tips and the other has 11 mm blunted tips. Curved blades are often used for tasks requiring a more angled approach. The tips of Castroviejo scissors are fine, allowing for precise entry into tissues without causing unnecessary trauma.
World Precision Instrument Spring Scissors, 14cm, Curved
Spring scissors are fine surgical instruments for making small, precision cuts. They are 14cm long, and fit comfortably into your hand. The longer spring scissors may fit more naturally in a larger hand. WPI offers spring scissors that range from 9.5 to 14cm in length. The spring mechanism that allows for smooth, precise cutting action, which reduces the risk of tissue damage or trauma. Choose either straight or curved for the 8mm blade. The curved surgical scissors are used in ophthalmology to make precise incisions in the cornea or delicate tissues. The curved tip gives greater visibility at the tip of the scissors. The straight blades are more often used in microdissection, microsurgery or plastic surgery. The spring handled surgical scissors are preferred by left-handed surgeons, because they can be used ambidextrously. This gives the left-handed surgeon a more natural cutting action, which means the surgeon has greater control of the tip and the cutting movement.
World Precision Instrument Tenotomy Scissors, 16 cm, Curved, Supercut
Tenotomy scissors are used for delicate procedures. With the long handle and thin tapered blades, the tenotomy scissors are able to cut tissues in hard to reach, limited spaces. These sharp, straight scissors make small, precision cuts, and they are perfect for delicate operations. The longer handles help to control the precision of these tenotomy scissors in restricted spaces or with delicate membranes or tissues, like brain tissue or ophthalmic surgeries. These scissors are designed for probing and cutting in tight spots. A precision pair of scissors like the tenotomy scissors limits the damage to surrounding tissues, which is critical in neurosurgery and other applications.
World Precision Instrument Noyes Scissors, 12 cm, Angled, Sharp/Sharp, 15 mm blades, German
Noyes Micro Scissors are a surgical instrument designed for ophthalmic surgery and are an ideal choice for microdissection or for delicate small animal surgeries. Named after their inventor, ophthalmologist Dr. Arthur Noyes, the Noyes Micro Scissors are characterized by their small size and fine tips. They let you make precise and controlled incisions. These surgical scissors are typically used for delicate tasks such as cutting fine structures, trimming tissue, or creating small openings. Noyes scissors are a type of spring scissors which can be used ambidextrously. For this reason, Noyes scissors are often preferred by left-handed surgeons.
These scissors are 12 cm (4.7") long and come with sharp/sharp, sharp/blunt, or blunt/blunt tips. On a sharp/sharp pair of scissors, both blades have sharp, pointed tips. These are used for precise cutting of delicate tissues. Use sharp/sharp tips when you need clean, accurate cuts. Blunt/blunt scissors have two blunt tips.
