Henrotin Weight Speculum

The Henrotin Weight Speculum is a specialized gynecological instrument used primarily for vaginal and pelvic examinations or procedures. It is designed to provide hands-free retraction of the vaginal walls, often during surgeries or procedures under anesthesia.

🔧 Design & Structure

• Type: Weighted, self-retaining vaginal speculum

• Components:

  • A single blade or bivalve retractor blade

  • A curved handle attached to a heavy weight that rests outside the vagina

• Weight: Typically ranges between 1 to 2 pounds (0.45–0.9 kg)

• Blade Shape: Broad and flat with a gentle curve, designed to retract the posterior vaginal wall

• Material: Surgical-grade stainless steel, making it autoclavable and reusable

---

⚙️ How It Works

• The speculum is inserted into the vaginal canal with the blade against the posterior wall.

• The weighted handle hangs down outside the body, using gravity to hold the blade in place and maintain constant downward traction.

• This exposes the cervix and upper vaginal walls, allowing the clinician to perform procedures or insert additional instruments without needing an assistant for retraction.

🩺 Clinical Applications

• Vaginal or pelvic surgery under anesthesia

• Colposcopy and LEEP procedures

• Pap smears or endometrial biopsy when extended access is needed

• Obstetric procedures such as evaluation of cervical dilation during labor

• Used especially in operating rooms due to its passive, gravity-based action

---

✅ Advantages

• Hands-free retraction improves procedural efficiency

• No locking mechanism or moving parts—simple and reliable

• Ideal for use during lengthy procedures requiring constant exposure

• Reduces the need for additional assistants during surgery

• Non-traumatic: blade design minimizes pressure on surrounding tissues

📝 Summary

The Henrotin Weight Speculum is a gravity-assisted, self-retaining retractor that provides effective exposure of the vaginal canal, especially the posterior wall. It is particularly useful in surgical or high-precision gynecologic procedures where prolonged, unobstructed access is required. Its weighted design offers a simple yet powerful mechanical advantage in maintaining retraction without manual effort.
