A Teat Dilator with Screw is a specialized veterinary instrument designed to gently and gradually dilate the teat canal in dairy animals. It features a screw-adjustable mechanism that allows controlled expansion, making it ideal for animals suffering from teat stenosis, fibrosis, or chronic mastitis. The screw system provides precise control during dilation, reducing trauma and improving treatment outcomes.

Packaging                                                             Individually packed (non-sterile or sterile)

•   Standard Screw-Type Teat Dilator – Straight with threaded expansion

•   Winged Handle Variant – For better grip during adjustment

•   Tapered Expandable Model – Begins narrow, expands smoothly as screw turns 

•   Surgical-Grade Stainless Steel – Provides strength, rust resistance, and longevity

•   ABS Plastic Handle (Optional) – Available in some models for ergonomic grip 

•   Veterinary Surgical Instrument

•   Mastitis & Teat Blockage Treatment Tool

•   Lactation Therapy Device

•   Reusable – Autoclavable metal tool

•   Packaged individually – Sterile or non-sterile based on supplier 

•   Dilation of narrow or fibrosed teat canals

•   Clearing blockages in chronic mastitis cases

•   Used post-surgery or injury for maintaining patency

•    Assists in medication administration through the teat

•   Ideal for animals with repeated teat issues or sphincter tightening 

•   Controlled dilation via screw mechanism = less trauma

•   Reusable and durable over long periods

•   Reduces pain caused by blocked or narrow teat canals

•   Assists in healing by maintaining open duct

•   Helps in reducing recurrence of fibrosis

•   Requires skill and care to avoid over-dilation

•   More expensive than disposable alternatives

•   May not be suitable for smaller animals (unless mini sizes used)

•   Improper use can worsen internal scarring

•   Always use the correct size for the animal

•   Sterilize before and after every use

•   Insert gently before expanding — do NOT force open

•   Monitor for signs of pain, bleeding, or resistance

•   Use only under veterinary supervision 

•   HS Code: 9018.90

•   HSN Code: 9018.90.99 Covers surgical instruments for veterinary/medical use. 

•   Hold by the base or handle during insertion

•   Turn screw slowly to expand

•   Observe for resistance – stop if pain or tension increases

•   Clean thoroughly and dry completely before storage

•   Keep away from moisture to prevent rusting

•   Autoclave Compatible: 121°C for 15–20 minutes

•   Can also be sterilized via:

o   Chemical Disinfection (e.g., glutaraldehyde soak)

o   Dry Heat Sterilization (if required)  

•   Common in cows and buffaloes, particularly high-producing dairy breeds

•   Used in cases of:

o Teat stenosis (narrowing of the canal)

o   Post-mastitis fibrosis

o   Chronic inflammation of the teat sphincter

•   Helps avoid surgical interventions in many cases

•   Maintains teat patency during recovery

•   Essential in field practice and on dairy farms with frequent mastitis cases 

•   Not used in modern human medicine

•   Teat dilators with screw mechanism are strictly veterinary tools

•   Human lactation issues are managed via:

o   Breast massage

o   Suction pumps

o   Medical consultation for blocked ducts

•   Use in humans is not approved or safe
