Metal drainage stent for pancreatic pseudocyst

Pancreatic pseudocyst refers to a cyst formed by inflammation of the pancreas and its surrounding tissues, leading to fluid accumulation. When a patient develops a pancreatic pseudocyst, drainage can be achieved by placing a pancreatic pseudocyst stent. Pancreatic pseudocyst stent usually refers to the drainage of fluid from the pancreatic pseudocyst through gastroscopy under ultrasound or CT guidance, thereby alleviating the patient's clinical symptoms.

Passive implant device is a stent used for ultrasound-guided resection and drainage of pancreatic pseudocysts and encapsulated necrosis. Its main function is to help drain the fluid and pus from pancreatic pseudocysts and encapsulated necrosis, in order to alleviate the symptoms of patients and promote their recovery.

Passive implantable devices are usually made of metal materials, which have good corrosion resistance and biocompatibility. Its design structure enables it to be accurately placed in the patient's pancreatic area under ultrasound guidance. Once placed, it can cut open the wall of a pancreatic cyst or necrotic tissue through electrocautery, allowing it to communicate with the normal tissue of the pancreas. In this way, the fluid and pus inside the cyst or necrotic tissue can be drained out through the stent, reducing the pressure and inflammatory response in the pancreatic region.

The drainage stent of passive implanted instruments usually has a certain degree of elasticity and adjustability to adapt to the anatomical structure and pathological conditions of different patients. Its design also takes into account the comfort and safety of patients to reduce possible complications and adverse reactions.

In general, the main function of the ultrasound-guided drainage stent for pancreatic pseudocysts and encapsulated necrosis using passive implantable instruments is to help drain the fluid and pus from pancreatic cysts and necrotic tissues, in order to alleviate patient symptoms and promote disease recovery. It is a safe and effective treatment method that can be precisely placed under ultrasound guidance, and has good biocompatibility and adjustability.
