Description

Technical Field

[0001] The invention relates to the technical field of pancreatic puncture, and in particular to a pancreatic puncture locator and a locating method thereof. Background Art

[0002] Acute pancreatitis is currently the most common cause of acute abdomen in my country; acute pancreatitis is divided into three types according to severity: mild, moderately severe, and severe. The mortality rate of patients with acute severe pancreatitis in world-class specialized diagnosis and treatment centers is around 20-30%, while the mortality rate in grassroots hospitals in my country is over 80%.

[0003] Therefore, the most important treatment for the late stage of pancreatitis and to avoid the death of patients is to perform peripancreatic necrotic tissue puncture and drainage; that is, to insert a tube from outside the body to construct a channel directly to the cystic cavity, so as to drain the necrotic fluid, flush the abscess cavity, and treat the source of infection; but there are still two problems: (1) The pancreas is a retroperitoneal organ; it is deeply buried under hollow organs such as the omentum and stomach; if the cystic cavity around the pancreas is to be punctured, it is inevitable to pass through some normal organs, and the organs pierced through are different according to different paths and angles; but it is very important to ensure that these "passing by" organs are not damaged; if the puncture needle penetrates the stomach or small intestine, it will directly cause intestinal fistula, which is a medical accident; (2) As mentioned above, to puncture the pancreas Even for normal people without pancreatitis who have formed peripancreatic wrapping, the path is very narrow; the abdominal cavity is like a box, and its size is basically fixed. Therefore, when the peripancreatic wrapping cyst cavity is formed, the original puncture path will become narrower; if you are not careful, it is very easy to damage normal organs; a straight tube is difficult to penetrate the skin, peritoneum and connective tissue on the path; the conventional or only method is to use a hollow needle, puncture the site, then pass a guide wire through the hollow part of the needle, and then withdraw the needle; then use a slightly thicker tube along the guide wire to insert into the cyst cavity for puncture. The operation process is cumbersome, which increases the operation time and causes a heavy burden on the doctor. The long operation makes the patient very painful, so we proposed a pancreatic puncture locator. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that in the prior art, a hollow thin needle is used to puncture the site, and then a guide wire is passed through the hollow part of the thin needle, and then the thin needle is withdrawn; and then a slightly thicker tube is inserted into the cyst cavity along the guide wire for puncture. The operation process is cumbersome, the operation time is increased, the doctor's operation burden is heavy, and the long operation makes the patient very painful. A pancreatic puncture locator is proposed to solve the problem that in the prior art, a hollow thin needle is used to puncture the site, and then a guide wire is passed through the hollow part of the thin needle, and then the thin needle is withdrawn; and then a slightly thicker tube is inserted into the cyst cavity along the guide wire for puncture.
