Description

Chromic Catgut Suture is a natural, absorbable surgical suture designed for effective wound closure in various medical procedures. Composed of purified collagen from the intestines of sheep, goat, or cattle, it undergoes chromic treatment to enhance performance by delaying absorption and reducing tissue reactivity.

Material and Structure

• Material: Purified collagen treated with chromic salts.
• Structure: Twisted multifilament with a smooth, polished finish for easy passage through tissue.
• Color: Brown, due to chromic treatment.

Absorption and Tensile Strength

• Absorption: The suture is absorbed through enzymatic proteolysis, with initial tensile strength retained for 10–21 days.
• Complete Absorption: Typically occurs within 70–120 days.

Sterilization and Packaging

• Sterilization: Achieved using ethylene oxide or gamma irradiation.
• Packaging: Available in sterile packs, often in aluminum foil, with color-coded brown identification.

Needle Options

Supplied with or without needles, offering various types such as round bodied, cutting edge, and taper point. Needles are crafted from stainless steel for durability.

Indications and Intended Use

Ideal for general soft tissue approximation and ligation, Chromic Catgut Suture is commonly used in:

• General surgery
• Obstetrics and gynecology
• Orthopedics
• Gastrointestinal surgery
• Urology
• Dentistry
• Ophthalmic and veterinary surgeries

Key Features

• Absorbable: Eliminates the need for removal.
• Biocompatible: Well-tolerated with minimal tissue reactivity.
• Knot Security: Offers good handling properties and smooth tissue passage.
• Cost-Effective: Widely used across various surgical fields.

Performance Considerations

Absorption rate and tensile strength may vary based on patient conditions such as infection or malnutrition. Not recommended for cardiovascular or neurological tissues where extended wound support is necessary.

Storage Instructions

• Store below 25°C and 50% relative humidity.
• Protect from heat, sunlight, and moisture.
• Single-use only; do not reuse or resterilize.

Compliance

Meets United States Pharmacopoeia requirements for natural absorbable surgical sutures, ensuring reliable performance and safety in medical applications.
