What is an HSG cannula set?

An HSG cannula set is a medical instrument kit used during a hysterosalpingography (HSG) procedure. This procedure is a specialized X-ray used to examine a woman’s uterus and fallopian tubes, primarily to investigate infertility or recurrent miscarriages.

What’s in an HSG Cannula Set?

An HSG cannula set typically includes:

1. HSG Cannula:
   A narrow, flexible or rigid tube inserted into the cervix to introduce contrast dye into the uterus and fallopian tubes. Types include:

   • Leech Wilkinson cannula (commonly used, screw-type tip)

   • Acorn or balloon cannula (has a balloon to seal the cervical opening)

2. Syringe or Connector:
   Used to inject the contrast medium through the cannula.

3. Speculum:
   (Often separate from the kit) Used to visualize the cervix during insertion.

4. Tenaculum or Forceps (optional):
   Used to hold or stabilize the cervix if needed.

5. Tubing:
   Sometimes included for better handling of dye injection.

Purpose of the HSG Procedure

• Evaluate fallopian tube patency (check if they are open or blocked)

• Assess uterine abnormalities (fibroids, polyps, adhesions, etc.)

Key Features of an HSG Cannula

• Atraumatic tip (to minimize cervical trauma)

• Leak-proof design (to ensure effective dye administration)

• Sterile and disposable versions are common
