- Blade no. 15
- Blade no. 10
- Blade no. 11
- Blade no. 12
Show Solution
The Correct Option is C
Solution and Explanation
Step 1: A scalpel blade with a long straight edge ending in a sharp spear-like tip is the No. 11. The tip, not a curved belly, is the working part.
Step 2: Because it stabs rather than slices, surgeons reach for the No. 11 to make a small entry: laparoscopic trocar sites, central venous and arterial line punctures, aortotomy, and debridement of valvular calcium.
Step 3: Contrast this with curved-belly blades. Nos. 10 and 15 carry a rounded cutting edge for skin incisions of differing length, and No. 12 is a curved sickle blade for tonsil and intra-oral work. Only the straight pointed profile fits the figure.
\[\boxed{\text{Blade no. 11}}\]
