[0005] The utility model provides the following technical solution: a laparoscopic biliary T-tube placement device, comprising a plastic sheath and a biliary T-tube, the biliary T-tube being bonded to the inside of the plastic sheath, a special chuck being bonded to the inner wall of the biliary T-tube, and a metal guide wire being arranged at the bottom of the special chuck.
[0006] Preferably, the inner arc size of the plastic sheath is matched with the outer arc size of the biliary T-tube, and the special chuck is located at the lower end of the biliary T-tube cavity.
[0007] Preferably, the models of the biliary T-tube are 14Fr, 16Fr, 18Fr, 20Fr, 22Fr and 24Fr, and the sizes of the biliary T-tube are 4.2mm, 4.8mm, 5.4mm, 6.0mm, 6.6mm and 7.2mm, and the models and sizes correspond to each other.
[0008] Preferably, the sizes of the plastic sheath are 4.8 mm, 5.4 mm, 6.0 mm, 6.6 mm, 7.2 mm and 7.8 mm.
[0009] Preferably, the sizes of the special chuck are 4.6 mm, 5.2 mm, 5.8 mm, 6.4 mm, 7.0 mm and 7.6 mm, and the sizes of the plastic sheath, special chuck and biliary T-tube are matched.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] The laparoscopic biliary T-tube placement device first applies glycerol to the plastic sheath outside the abdominal cavity before use, and moistens the inner wall of the plastic sheath with glycerol. Then, the operation outside the abdominal cavity is continued, and a metal guide wire with a special clamp is inserted into the plastic sheath for placement. A special clamp is used outside the sheath to clamp one side edge of the biliary T-tube, and then the biliary T-tube is pulled out of the sheath through the sheath, and a special clamp is deployed outside the sheath to release one side edge of the biliary T-tube, and the biliary T-tube is pushed back into the plastic sheath, and the plastic sheath is placed around the abdominal bile duct through the laparoscopic Trocar hole, and a special clamp is used. Gently push the head end to push the biliary T-tube out of the sheath through the sheath and accurately place it at the bile duct opening. The head end of the biliary T-tube elastically expands the original "T-shaped" arm and is naturally placed in the bile duct to complete the operation. During the entire operation, the sheath is relatively long and can be used through a laparoscopic Trocar to directly reach the patient's bile duct opening, making T-tube placement simple and efficient. The special chuck has a metal clip with a bean sprout structure at the head end. The bean sprout structure can push the T-tube forward to the bile duct opening in the sheath during the above operation. According to different models of T-tubes, sheaths and special chucks of different diameters are designed, which are more practical. BRIEF DESCRIPTION OF THE DRAWINGS

[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 1-4A laparoscopic bile duct T-tube placement device comprises a plastic sheath 1 and a bile duct T-tube 2. The sheath is relatively long and can directly reach the opening of the patient's bile duct through a laparoscopic Trocar, making T-tube placement simple and efficient. The inside of the plastic sheath 1 is bonded with the bile duct T-tube 2. The inner wall of the bile duct T-tube 2 is bonded with a special chuck 4. The special chuck 4 has a metal clip with a bean sprout structure at the head end. The bean sprout structure can push the T-tube forward to the bile duct opening in the sheath during operation. A metal guide wire 3 is arranged at the bottom of the special chuck 4. The inner arc size of the plastic sheath 1 is adapted to the outer arc size of the bile duct T-tube 2. According to different models of T-tubes, sheaths and special clamps of different diameters are designed, and the corresponding sizes can be adapted according to the attached drawings in detail, which is more practical. The special clamp 4 is located at the lower end of the cavity of the biliary T-tube 2. Before use, glycerol is first applied to the plastic sheath 1 outside the abdominal cavity, and the inner wall of the plastic sheath 1 is moistened with glycerol. At this time, the operation outside the abdominal cavity is continued, and the metal guide wire 3 with the special clamp 4 is inserted into the plastic sheath 1. The special clamp 4 is used to clamp one side edge of the biliary T-tube 2 outside the sheath, and then the biliary T-tube 2 is pulled out of the sheath through the sheath, and the special clamp 4 is unfolded outside the sheath to release the Release the edge of one side of the bile duct T-tube 2, push the bile duct T-tube 2 back into the plastic sheath 1, insert the plastic sheath 1 into the peritoneal bile duct through the laparoscopic Trocar hole, use the special clamp 4 to gently push, push the bile duct T-tube 2 out of the sheath through the sheath, and accurately place it at the opening of the bile duct.
