Single-use Percutaneous Drainage Kit: Dual-Guidewire Pigtail Drainage Set
- Commodity name： Single-use Percutaneous Drainage Kit: Dual-Guidewire Pigtail Drainage Set
- Description
-
This kit combines dual-guidewire guidance with a pigtail curled catheter to safely complete puncture, dilation and indwelling drainage under imaging guidance (ultrasound or CT).
Core components
- Pigtail drainage catheter: tip curls into a pigtail with multiple side holes; shaft has clear centimeter markings; distal end has a pull-string lock and three-way connector to secure the curl and connect a drainage bag.
- Dual guidewires and puncture needle: usually two guidewires (or one primary plus one assist) and a puncture needle. After successful puncture the wire enters the collection cavity and provides a stable track for dilators and catheter placement.
- Dilator: advances over the wire to dilate subcutaneous tissue and the tract so a larger drainage catheter can enter the cavity.
- Other accessories: syringe (aspiration/flush), three-way stopcock, catheter fixation device (white disc), sterile dressing and connection tubing.
Dual guidewire + pigtail advantages
- Dual guidewire: safety redundancy for complex puncture near vital organs or vessels; a second wire helps maintain the channel if one migrates.
- Pigtail shape: cavity anchoring reduces dislodgement; side holes on the curl reduce wall suction and help keep drainage patent.
Clinical applications
- Thorax and pericardium: pleural effusion, pneumothorax, pericardial effusion.
- Abdomen and solid organs: liver abscess, acute obstructive cholecystitis, peripancreatic or retroperitoneal localized fluid/pus.
- Urinary system: hydronephrosis, renal abscess percutaneous drainage.
- Biliary system: intrahepatic biliary catheter drainage for obstruction and infection.
Standard workflow (Seldinger)
- Image-guided puncture and aspiration confirmation.
- Guidewire placement; remove needle, leave wire in place.
- Dilate the tract over the wire, then withdraw the dilator.
- Advance the pigtail catheter; lock the tip curl when fully inside the cavity.
- Flush, connect drainage bag, and secure with fixation device and sutures.
