The ratchet-style calf delivery aid is a veterinary obstetric device used to assist in the delivery of calves when a cow is experiencing dystocia.

Structural Components

1. Two high-strength threaded main rods: Threaded to provide push-and-pull travel; blue protective caps at the rod ends;

2. Ratchet locking mechanism + blue non-slip handle: The core drive component; repeatedly pressing the handle generates pulling force, and the ratchet locks the force in place, eliminating the need for continuous effort;

3. L-shaped support frame: Resting against the outer side of the cow’s hindquarters, serving as a force fulcrum;

4. Obstetric chain: Hung from both ends of the L-frame; during delivery, it is secured around the calf’s legs to transmit pulling force.

Usage

Used in cases of dystocia (such as insufficient labor force or a macrosomic fetus):

The chain secures both of the calf’s legs, while the L-shaped support frame rests against the outside of the cow’s pelvis. Pressing the handle engages the threaded ratchet to slowly and controllably pull the calf out. **This method is safer than manual pulling and reduces the risk of injury to both the cow and the calf**. It is commonly used in large-scale cattle farms and dairy operations.

Material Features

Made entirely of steel or stainless steel with rust-proof treatment on the metal surfaces; features a heavy-duty load-bearing structure that can be repeatedly disinfected and reused; the ratchet mechanism ensures stable control of pulling force and prevents sudden release of tension.
