Which instrument is used to castrate by crushing the spermatic cord?

Explanation:
Castration by crushing the spermatic cord relies on a tool that both crushes and transects the cord to stop blood flow quickly. The emasculator is designed for this purpose: it clamps, crushes the cord to seal the vessels, and then cuts, providing immediate hemostasis. The other instruments serve different roles—an elastic band tool (elastrator) constricts the cord to cut off blood supply rather than crushing and ligating; a Newberry knife is used for incising tissue, not for crushing the cord; and a scalpel is a general cutting blade without a built‑in crushing/hemostatic action.
