Introduction to Surgical Scissors
Surgical scissors are essential tools in any medical procedure, designed for precision cutting of tissues, sutures, and other materials. These instruments come in various shapes and sizes, each tailored to specific surgical needs. Hamsan Surgical, we recognize the critical role that high-quality surgical scissors play in ensuring successful outcomes in surgeries.
Historical Background
The use of cutting instruments in medicine dates back thousands of years. However, modern surgical scissors, as we know them, began to evolve in the 19th century with advancements in metallurgy and precision manufacturing. The first standardized surgical scissors were developed to meet the growing demands for accuracy and safety in surgery.
Materials Used in Surgical Scissors
The choice of material in surgical scissors is crucial for their durability, performance, and ability to be sterilized. The most common materials include:
Stainless Steel
- Over 90% of surgical scissors are made from stainless steel due to its corrosion resistance and ease of sterilization.
Tungsten Carbide
- Often used for the cutting edges to provide enhanced durability.
- Scissors with tungsten carbide inserts last up to 20 times longer than standard stainless steel scissors.
Titanium
- Lightweight, strong, and non-magnetic, making it ideal for delicate surgeries.
- Titanium scissors are 50% lighter than their stainless steel counterparts, reducing hand fatigue during long procedures.
Design and Structure of Surgical Scissors
The design of surgical scissors varies depending on their intended use. Key design elements include.
Blade Types
- Sharp vs. Blunt: Sharp blades are used for precise cuts, while blunt blades are safer for handling delicate tissues.
