Novel tee duct for minimal invasive surgery for pancreatitis

Abstract

The invention discloses a novel tee duct for minimal invasive surgery for pancreatitis, and particularly relates to the technical field of a medical care duct. The tee duct comprises a casing pipe, wherein a liquid inlet pipe is fixedly arranged at one end of the casing pipe, water pervious holes are formed in the outer side of one end of the casing pipe, an internal casing pipe is arranged in thecasing pipe in a sleeving manner, the liquid inlet pipe and the internal casing pipe are the same in lengths, a first connection tee pipe is fixedly arranged at one end of the liquid inlet pipe, anda second connection tee pipe is fixedly arranged at one end of the internal casing pipe; and medicine injecting back flushing pipes are fixedly arranged on one side of the first connection tee pipe and one side of the second connection tee pipe, and each plugging plug is fixedly connected to the outer side of the corresponding medicine injecting back flushing pipe. The liquid inlet pipe and the outer end of the internal casing pipe are aligned, so that the internal casing pipe is confirmed to be inserted into the inner end of the casing pipe. The tee duct disclosed by the invention is simple and accurate to operate, the insertion length of the internal casing pipe is accurate to position, the internal casing pipe can be drawn out from the casing pipe, the duct is convenient to carry by a patient, the patient can come down to walk, and rehabilitation and motion of the patient are not impeded.

Description

technical field [0001] The invention relates to the technical field of medical catheters, in particular to a novel three-way catheter for minimally invasive surgery on pancreatitis. Background technique [0002] The pancreas is a long and narrow gland, which is placed horizontally on the plane of the 1-2 lumbar vertebrae on the posterior abdominal wall. It is soft in texture and gray-red in color. It is an organ deep in the human abdomen. The pancreas is divided into exocrine glands and endocrine glands. Exocrine glands are composed of acini and ducts, the acini secrete pancreatic juice, and the ducts are the channels through which the pancreatic juice is discharged. Pancreatic juice contains sodium bicarbonate, trypsinogen, lipase, amylase, etc. Pancreatic juice is discharged into the duodenum through the pancreatic duct, which has the function of digesting protein, fat and sugar. Pancreatitis is a disease caused by the self-digestion of trypsin in the pancreas. The panc...

Problems solved by technology

[0005] Therefore, the embodiment of the present invention provides a new three-way catheter for minimally invasive pancreatitis surgery. By aligning the liquid inlet tube with the outer end of the inner cannula, it is possible to confirm whether the inner cannula is inserted into the inner end of the cannula. The operation is simple and accurate. The positioning of the insertion length of the cannula is accurate, and the inner cannula can be pulled out from the cannula, which is convenient for the patient to carry the catheter, and allows the patient to walk down and walk without hindering the patient's rehabilitation and activities, so as to solve the inaccurate insertion length of the inner cannula in the prior art , affect the pumping effect of the drug solution, and the implanted catheter affects the patient's activities, causing problems
