Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a T-shaped bile duct drainage tube. Background Art

[0002] T-tube is the common bile duct incision T-tube drainage, which is a commonly used drainage tube in hepatobiliary surgery.

[0003] Generally, during biliary surgery, the bile duct is cut open and sutured in the first stage. However, bile fistula may occur after the surgery, so T-tube drainage is required during the operation. The T-tube can maintain the normal shape of the lumen, which can not only avoid bile duct stenosis, but also drain bile to the outside of the body, reduce the pressure in the bile duct, and prevent bile fistula after the surgery.

[0004] Although common bile duct incision and T-tube drainage is a commonly used drainage tube in hepatobiliary surgery, it is not suitable for all patients. It is only used in cases of cholangitis, obstruction, gallstones, and cholecystectomy. If a patient with common bile duct incision and T-tube drainage also needs gallbladder removal, the patient will undergo common bile duct incision and T-tube drainage, followed by gallbladder removal.

[0005] Patients who undergo common bile duct incision and T-tube drainage should take local hygiene and care measures, and also monitor their body temperature regularly to see if it is within the normal range.

[0006] Since the T-tube is in a "T" shape, it may cause damage to the organs during placement and removal. Therefore, a T-type bile duct drainage tube is proposed. Utility Model Content

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3 The utility model provides a technical solution: a T-shaped bile duct drainage tube, comprising a main body 1 and a T-shaped tube 2, wherein the T-shaped tube 2 comprises a vertically arranged vertical tube and a horizontally arranged horizontal tube, such as Figure 1As shown, the main body 1 is a tubular structure, one end of the main body 1 is fixedly connected with a T-shaped bending part 3, and the T-shaped bending part 3 is in a three-way shape to facilitate the insertion and removal of the device. The bottom end of the T-shaped tube 2 is arranged inside the main body 1, that is, the vertical tube part of the T-shaped tube 2 is located inside the main body 1 and fits with the inner wall of the main body 1, and the two ends of the T-shaped tube 2 pass through the two ends of the T-shaped bending part 3 respectively, that is, the horizontal tube part of the T-shaped tube 2 passes through the T-shaped bending part 3 and is located on the outside of the T-shaped bending part 3. Both ends of the bending portion 3 are fixedly connected with telescopic tubes 4, which are sleeved on the outside of the T-tube 2, and the walls of the telescopic tubes 4 are respectively provided with cavities 5, the inside of the main body 1 is provided with an air inlet pipe 6 connected with the cavity 5, and the outer surface of the main body 1 is fixedly connected with an interface 7 connected with the air inlet pipe 6, and gas is injected through the interface 7, and the gas enters the cavity 5 through the air inlet pipe 6, so that the telescopic tube 4 drives the transverse tube part of the T-tube 2 to expand, so as to prevent the T-tube 2.

[0019] Specifically, the T-tube 2 is slidably connected to the main body 1, and the T-tube 2 is located outside the main body 1, so that when the T-tube needs to be removed, the T-tube 2 is pulled out from the bottom of the main body 1, and the transverse tube part of the T-tube 2 is retracted into the T-shaped bending part 3, thereby facilitating the extraction of the device.

[0020] Specifically, a connecting hole 8 for connecting the two cavities 5 is provided inside the tube wall of the T-shaped bending portion 3. When gas is injected, the gas can cause the telescopic tubes 4 at both ends to expand synchronously.

[0021] When the utility model is in use, the T-tube 2 is in a folded state, and the device is easy to insert. Then gas is injected through the interface 7, and the gas enters the cavity 5 through the air inlet pipe 6 and the connecting hole 8, driving the telescopic tube 4 to expand, and then driving the T-tube 2 to unfold, which is convenient for the setting of the T-tube 2. When the device needs to be removed, the T-tube 2 is pulled out from the bottom of the main body 1, and the T-tube 2 is retracted into the T-shaped bending part 3, so that the device can be removed to reduce damage.
