A hysteroscope is a thin, tube-like instrument equipped with a camera and light, used to examine the inside of the uterus (womb). A 2.9 mm, 30-degree hysteroscope is a specific type of hysteroscope characterized by its small diameter (2.9 mm) and an angled view (30 degrees), which provides enhanced visibility and maneuverability during diagnostic and surgical procedures.

Key Uses:

1. Diagnostic Procedures:

   • Evaluating abnormal uterine bleeding.
   • Investigating infertility or recurrent miscarriages.
   • Examining uterine abnormalities such as fibroids, polyps, or adhesions (scar tissue).
   • Diagnosing endometrial cancer or hyperplasia.

2. Operative Procedures:

   • Removing uterine polyps or small fibroids.
   • Treating intrauterine adhesions (Asherman’s syndrome).
   • Conducting endometrial ablation for heavy menstrual bleeding.
   • Retrieving misplaced intrauterine devices (IUDs).

Advantages of a 2.9 mm Diameter:

• Minimally Invasive: Causes less discomfort and is suitable for outpatient or office-based procedures.
• No Need for Cervical Dilation: The small size often eliminates the requirement for extensive cervical dilation, making the procedure quicker and less painful.
• Improved Patient Tolerance: Ideal for diagnostic procedures in patients without prior vaginal deliveries or with narrow cervices.

Advantages of a 30-Degree View:

• Wider Field of Vision: Provides an angled perspective, allowing the surgeon to visualize more of the uterine cavity without repositioning the hysteroscope.
• Enhanced Visualization: Useful for assessing areas that might be difficult to see with a straight (0-degree) scope.

This type of hysteroscope is a valuable tool in gynecology for both diagnostic and therapeutic purposes, offering a minimally invasive approach to uterine evaluation and treatment.

A cystoscopy sheath is a medical instrument used in cystoscopy, a procedure that involves the examination of the inside of the bladder and urethra using a specialized camera called a cystoscope. The cystoscopy sheath serves as the protective outer casing through which the cystoscope is inserted into the urinary tract, allowing for the introduction of the scope, as well as other instruments, such as forceps, lasers, or biopsy tools, during the procedure.
