Cirrhosis is a common chronic progressive liver disease in clinic. It is a diffuse liver damage caused by long-term or repeated effects of one or more causes. In my country, most of them are post-hepatitis cirrhosis, and a few are alcoholic cirrhosis and schistosomiasis cirrhosis. According to the requirements of the hospital, we cooperated in the design of this cirrhosis puncture kit.

Liver puncture examination is an important means to diagnose and understand the condition of patients with liver cirrhosis. The design of liver cirrhosis puncture kit is produced for the smooth progress of the whole examination. Transjugular intrahepatic puncture device (referred to as "TIPS puncture device") is the world's first minimally invasive interventional treatment device with "double needle configuration", which provides a reliable treatment for portal hypertension.

The instrument joint is designed to be petal shaped; the puncture sleeve with the outer diameter of the head end as low as 4F makes the puncture wound small and has fewer complications; the double needle configuration with three-sided needle and conical needle effectively improves the probability of successful puncture; outer sheath The hydrophilic coating on the outer wall of the tube can reduce its friction damage to blood vessels, reduce patient pain, and improve the doctor's control. In clinical application, the efficiency and success rate of TIPS are greatly improved.

Design concept: 1. Flowers are the blooming of life. Let patients feel the hope of life; 2. The petal-like gear makes the operation of medical staff more convenient and conforms to the man-machine; 3. The product is integrally formed, which has the stability of medical products; the double needle configuration improves the success rate of puncture. Reduce puncture resistance and trauma, reduce patient pain. Advanced water coating makes the catheter smoother.
