Embodiment 1
[0034] refer to figure 1 , image 3 , Figure 4 and Figure 5 , a kind of bear jejunum drainage catheter and the manufacturing method of longitudinal fold bile, comprise the following steps:
[0035] a. Open the abdomen and create longitudinal folds at the bottom of the gallbladder: cut the white line 2 cm away from the front of the bear's navel 12 to 14 cm on the right side, and cut 10 cm forward parallel to the white line (for 4-5-year-old bears) prevail), lead the gallbladder (1) to the incision, place a traction line and extract bile, make a 1 cm small incision at the bottom of the gallbladder, and then make longitudinal folds (6); the number of artificial longitudinal folds is 4 Firstly, the wrinkled part is located 3-3.5 cm above the bottom of the gallbladder, and on the same horizontal line, four places of the bottom of the gallbladder - front, back, left and right - are respectively placed with fixed lines. exist Figure 4 The middle suturing needle avoids blood v...
Embodiment 2
[0042] refer to figure 2 , image 3 , Figure 4 and Figure 5 A method for producing bear gallbladder drainage catheter and vertical folds for bile extraction, comprising the following steps:
[0043] a. Open the abdomen and create longitudinal folds at the bottom of the gallbladder: on the right side 12-14cm in front of the navel of the bear, cut 2cm away from the alba linea, incise 5-8cm forward parallel to the alba line, or 3 cm behind the sword Cut back at -4cm, (in the past, when determining the surgical incision, the sword was used as the standard, and the required length was cut backward. The sword is invisible and can only be determined by touch. It is difficult to judge fat bears. , the incision is often front to back, and sometimes the incision is too front, and sometimes the diaphragm is cut through during laparotomy. In addition, the abdominal wall here is thick, tense, less mobile, and bleeding is more, which brings great difficulties to the operation. Delay ...
