Abstract

The invention belongs to the technical field of medical supplies, and particularly discloses a puncture assembly for DIPS. The puncture assembly comprises an adjustable bent sheath, an expansion tube, a catheter and a puncture needle which are sequentially sleeved from outside to inside; and the adjustable bent sheath comprises a sheath tube and a connector, the end, away from the connector, of the sheath tube is a bending part with the adjustable bending degree, and a bending adjusting handle for adjusting the bending degree of the bending part is arranged on the connector. Compared with the prior art, when the puncture assembly is used in a vein puncture operation, the operation cost and the operation difficulty can be reduced, and the success rate of the operation and the long-term patency rate of a gate cavity runner are greatly increased.

Description

technical field [0001] The invention belongs to the technical field of medical supplies, and specifically discloses a puncture assembly for DIPS. Background technique [0002] For patients with liver cirrhosis, non-cirrhotic portal hypertension, portal vein thrombosis, Budd-Chiari syndrome and other diseases, patients with variceal rupture and bleeding, as well as patients with refractory ascites caused by long-term liver cirrhosis, Budd-Chiari syndrome, and small hepatic venous occlusion For complex conditions such as portal vein thrombosis, portal vein aneurysm, and cavernous degeneration of the portal vein, venipuncture surgery is required. my country is a big country with viral hepatitis. There are many patients with gastrointestinal bleeding and intractable ascites caused by various types of hepatitis. In an emergency, surgical treatment can quickly relieve symptoms and save the lives of patients. [0003] The original operation is to use the puncture component to punc...
