Inverse insertion nasobiliary tube

Abstract

The invention discloses an inverse insertion nasobiliary tube. The inverse insertion nasobiliary tube comprises a main drainage tube and a nasobiliary drainage tube, wherein the diameter of the main drainage tube is smaller than that of the nasobiliary drainage tube; the main drainage tube is in smooth connection with the nasobiliary drainage tube; the length of the main drainage tube is between 110 and 130 centimeters; a traction hole is formed at the tail end of the main drainage tube; the length of the nasobiliary drainage tube is between 25 and 35 centimeters; a plurality of drainage holes are formed in the nasobiliary drainage tube; the drainage holes in the nasobiliary drainage tube are arranged symmetrically in a mode that two drainage holes form a pair; the space between each pairof the drainage holes is between 1.5 and 1.8 centimeters; the adjacent drainage holes are arranged in a staggered manner; the nasobiliary drainage tube comprises an upper part and a lower part which are distinguished by two colors; and the length of the upper part is two thirds of that of the nasobiliary drainage tube. The inverse insertion nasobiliary tube is simple and reasonable in structure and convenient to use, and bile leakage in primary suture of bile duct after choledocholithotomy is effectively prevented; moreover, the standing time is short, and the pain of patients is relieved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a reverse-inserted nasobiliary duct used for common bile duct stone removal after one-stage suturing of the common bile duct to prevent bile leakage. Background technique [0002] With the rapid development of minimally invasive surgical techniques, laparoscopic cholecystectomy (LC) and laparoscopic common bile duct stone extraction (LCBDE) have been widely used clinically. When all the stones are removed, more and more doctors tend to adopt one-stage suture of the common bile duct, which reduces the pain of patients compared with the original suture that needs to place the T-shaped tube in the abdomen for about 2 months , It also brings convenience to the life of the patient; however, in the actual clinical application process, it is found that the one-stage suturing of the common bile duct has a relatively high incidence of bile leakage due to postoperative biliary pres...

[0002] With the rapid development of minimally invasive surgical techniques, laparoscopic cholecystectomy (LC) and laparoscopic common bile duct stone extraction (LCBDE) have been widely used clinically. When all the stones are removed, more and more doctors tend to adopt one-stage suture of the common bile duct, which reduces the pain of patients compared with the original suture that needs to place the T-shaped tube in the abdomen for about 2 months , It also brings convenience to the life of the patient; however, in the actual clinical application process, it is found that the one-stage suturing of the common bile duct has a relatively high incidence of bile leakage due to postoperative biliary pressure, which increases the pain of the patient.
