The O’Connor–O’Sullivan retractor is a specialized self-retaining surgical instrument commonly used in abdominal and pelvic surgeries. Known for its strong retraction capability and adjustable design, this retractor provides surgeons with a clear, unobstructed view of the operative field—making it an essential tool in major open surgical procedures.

What Is the O’Connor–O’Sullivan Retractor?

The O’Connor–O’Sullivan retractor is a self-retaining ring retractor system consisting of:

• A central ring frame

• Movable lateral blades

• Depressor blades

• A locking mechanism

Its unique circular frame, along with multiple interchangeable blades, allows surgeons to customize retraction according to the anatomical needs of the patient.

This retractor is widely used in gynecological, obstetric, and general abdominal surgeries, especially where deep cavity exposure is required.

Key Features of the O’Connor–O’Sullivan Retractor

✔ Self-Retaining Mechanism

Once positioned and locked, it stays in place without manual holding, allowing the surgical team to work freely.

✔ Circular Ring Design

Provides 360-degree access and excellent exposure to deep cavities.

✔ Interchangeable Blades

Available in different sizes and shapes, ensuring precise retraction for:

• Abdominal walls

• Pelvic organs

• Soft tissues

✔ Stainless Steel Construction

Highly durable, corrosion-resistant, and suitable for repeated sterilization.

✔ Adjustability

Blades can be repositioned during surgery to improve visualization and reduce tissue stress.

Common Surgical Uses

The O’Connor–O’Sullivan retractor is primarily used in:

1. Gynecological Surgeries

• Hysterectomy

• Myomectomy

• Ovarian procedures

Gynecologists prefer this retractor for its superior pelvic exposure.

2. Obstetric Surgery

Especially valuable in:

• Cesarean sections

• Procedures involving deep pelvic access

3. General Abdominal Surgery

Used in open surgeries where wide exposure is needed, such as:

• Bowel surgery

• Appendectomy

• Exploratory laparotomy

• Tumor removal

4. Urological Procedures

Helps expose deep pelvic structures for improved precision.

Advantages of Using the O’Connor–O’Sullivan Retractor

✔ Enhanced Visibility

Its strong retraction and ring-shaped design keep tissues securely separated.

✔ Improved Surgical Efficiency
