Which device would typically not be included as part of basic surgical instruments?

The thyroid shield is typically not included as part of basic surgical instruments because its primary use is to protect the thyroid gland during radiation exposure procedures rather than for surgical manipulation or incision work. In contrast, a scalpel, dental elevator, and spay hook are all essential surgical tools used during various surgical procedures. The scalpel is used for making incisions, the dental elevator is utilized in dental surgeries to elevate teeth or bone, and the spay hook assists in exposing the ovarian and uterine structures during spay surgeries. Understanding the specific functions and applications of surgical instruments is crucial for effective veterinary practice.
