Scissors
The choice of surgical scissors is large. They can be long or short, strong or fine blunt or sharp pointed, straight or curved either on the flat side or on the edge.
More expensive scissors have tungsten edges which are sharp, tough and long lasting.
The choice will depend on many factors and the surgeon’s preference is perhaps of most importance.
• For surgical cutting, short scissors are appropriate, and long scissors are used in deep dissection as in thoracic and pelvic surgery.
• Curved scissors are more popular for dissection because, with the convexity of blades pointing away from the surgeon, structures being cut on both sides of the tip are visible.
It should be realized that the longer the instruments the more pronounced is the tremor transmitted. The varieties of scissors in use are:
• Mayo (Fig. 8.32)
• McIndoe (Fig. 8.33)
• Nelson (Figs 8.34A and B)
• Metzenbaum (Figs 8.35A and B)
• Lloyd Davies (Fig. 8.36)
• Abel (Fig. 8.37)
• Potts (Fig. 8.38)
• DeBakey (Fig. 8.39)
• Microvascular (Fig. 8.40)
• Satinsky (Fig. 8.41)
Potts, DeBakey and Microvascular are the scissors used in vascular surgery.
