Description

External drainage device for gall pancreas

Technical Field

The device relates to the field of drainage devices, in particular to an external drainage device for gall bladder and pancreas.

Background

1. Pancreatic duct external drainage:

pancreas (head) duodenal resection has more serious consequences due to delayed gastric emptying, abdominal infection and even bleeding risks caused by pancreatic fistulae, which involve more vascular dissection in the area surrounding the pancreas head and multiple anastomoses (gastric-jejunum, pancreas-jejunum, bile duct-jejunum anastomoses). Therefore, enhancing the unobstructed drainage of pancreatic juice after operation becomes a main measure for reducing the incidence rate of B+C grade pancreatic fistula. Drainage of pancreatic juice to the outside of the body by placement of the main pancreatic duct drainage tube significantly reduces the rate of pancreatic fistula growth and is therefore favored by many pancreatic surgeons. However, there is no professional pancreatic duct external drainage device clinically so far. The surgeon typically looks for a properly sized ventricular drainage tube, after surgical trimming, inserts its tip into the main pancreatic duct, and passes the other end through the pancreas-jejunum stoma, out the contralateral jejunal wall, and out the abdominal wall to the outside. After the external infusion device is used, an infusion device joint with a proper size is found, one end of the infusion device joint is in butt joint with the ventricular drainage tube, the other end of the infusion device joint is in butt joint with the catheter opening of the urine collection bag, the middle of the infusion device joint is fixed by using an adhesive tape, and pancreatic juice is drained to the urine collection bag by the method, so that the aim of external pancreatic juice drainage is achieved. However, there are a number of drawbacks to this approach, mainly manifested in the following aspects:

1) The front end of the ventricular drainage tube is blunt, temporary trimming is needed in the operation to insert the main pancreatic duct, and simultaneously drainage holes are needed to be trimmed at two sides to achieve the purpose of unobstructed drainage. However, sharp edges exist in both the temporarily trimmed tip and the drainage hole, which may damage the endothelium of the pancreatic duct during placement drainage, causing bleeding and traumatic pancreatitis, resulting in delayed wound healing.

2) The rear end of the drainage tube is provided with a standard joint, if the joint is not firm, pancreatic juice leakage and accidental slipping are easily caused, surrounding clothes are polluted, and even the skin of a patient is corroded. If the connection port is polluted carelessly, the reverse drainage tube of bacteria is easy to ascend, and the abdominal cavity infection is caused.

3) The common urine collecting bag is not provided with a one-way valve for preventing reverse flow, for example, pancreatic juice is easy to flow into the abdominal cavity in reverse flow because a patient carelessly lifts the urine collecting bag to exceed the abdomen, so that abdominal infection is caused, and the risk of pancreatitis is induced.

2. Bile duct external drainage:

bile duct-jejunal anastomosis is a major component of standard pancreatic duodenal resection. For patients with small bile duct diameter or preoperative bile duct inflammation or calculus, it is expected that bile duct lower end stenosis or even obstruction is caused by scar contracture of an anastomotic stoma after biliary-intestinal anastomosis, bile discharge is blocked, obstructive jaundice is caused, and liver function is damaged. For such patients, it is common practice for pancreas and biliary tract surgeons to place a "T-shaped" outer drainage tube of the common bile duct to support the wall of the bile duct, prevent scar contracture, and remove the bile duct after the bile duct heals and forms stably. The T-shaped tube is made of latex tube, and is trimmed properly during operation, and after trimming, one end of the T-shaped tube is placed into the bile duct, and the other end of the T-shaped tube passes through the bile duct-jejunum anastomosis opening and then passes out of the jejunum side wall, and is led out of the body from the abdominal wall. And the other way is to select the ventricle drainage tube to be trimmed and then put into the common bile duct as a bile duct support tube to be led out of the body from the abdominal wall by referring to the pancreatic duct external drainage. After the drainage tube is pulled out of the body, the bile duct outer drainage tube is connected with the catheter of the urine collecting bag by searching an intermediate joint, so that the purposes of bile duct forming fixation and bile outer drainage are achieved. The drainage device is also formed by manual splicing, and no professional bile duct external drainage device exists at present. The prior external drainage device mainly has the following defects:

4) The joint of the bile duct external drainage tube and the urine collecting bag catheter is formed by manual splicing, and the risk of easy leakage and accidental slipping is provided.

5) The drainage bag for collecting bile has no anti-backflow function design.
