The Closest Thing to the Real Procedure Without the Risk

The Erler-Zimmer Equine Castration Surgical Simulator is a purpose-built, highly realistic training model that lets veterinary students, technicians, and surgeons practice the complete closed equine castration procedure in a fully controlled, repeatable environment. The model features consumable fluid-filled silicone testicle and spermatic cord modules, a tissue-analogue housing, and a gravity-fed simulated blood system to validate hemostasis, delivering the kind of tactile and procedural realism that textbooks and videos simply cannot replicate. Whether you're running a first-year vet school skills lab or sharpening surgical technique before a live procedure, this simulator is the training investment your program needs. Order yours today!

Every Step of the Procedure, Practiced to Perfection

Equine castration is one of the most commonly performed surgical procedures in equine veterinary practice and one of the highest risk for complications when technique is poor. This simulator addresses this directly by allowing learners to walk through the entire closed castration workflow from start to finish: skin incision, blunt dissection, spermatic cord isolation, ligature application, and emasculator use. Veterinary students, technicians, and surgeons can practice every step while receiving immediate feedback on surgical technique, making each session a genuine learning loop rather than a passive demonstration. The gravity-fed blood simulation system specifically validates hemostasis technique, giving instructors a concrete, observable measure of procedural quality that is impossible to fake or skip past.

Built for the Way Vet Schools Actually Train

Large cohorts, limited animal access, and the pressure to graduate procedure-ready clinicians — the VET4810 was designed with all of that in mind.

• Rapid turnaround between users: The quick-deploy retention system allows for rapid module changes between users, enabling efficient training for large groups, no lengthy reset time between students in a packed skills lab.
• Consumable, replaceable modules: Fluid-filled silicone testicle and spermatic cord modules are designed to be used and replaced, so the training experience stays consistent session after session. Replacement testicles and replacement skin are available separately.
• Immediate hemostasis feedback: The gravity-fed blood system makes ligature and emasculator technique directly observable — instructors can spot errors in real time and learners understand the consequences of poor technique without a live animal being harmed.
• Ideal audiences: Veterinary medicine students, equine surgery residents, vet tech programs, equine continuing education courses, and simulation-based veterinary training centers.
• Ethical and sustainable training: Reduces reliance on cadaveric or live-animal procedures during skills acquisition, supporting both animal welfare goals and the practical constraints of modern veterinary curricula.
