● An adult upper body with anatomical landmarks, including anatomical structures such as clavicle, complete ribs, sternum, nipple, umbilicus, groin, anterior superior iliac spine, etc., which facilitate the positioning of surgical operations.

● Made of polymer materials, it has a soft touch, a real feel and a high degree of simulation.

● Operation holes can be established through the skin to simulate laparoscopic cholecystectomy, the location of the
operation hole:

● Observation hole: The umbilicus, an arcuate incision at the lower edge of the umbilical fossa, approximately 10 mm, is
used to make pneumoperitoneum.

● Main operation hole: Cut a transverse incision of 1 cm 1 cm below the xiphoid process and insert a 10 mm trocar to insert
the electrocoagulation hook.

● Auxiliary operation hole: Cut a 5mm incision 1cm below the costal midline, and insert a 5mm trocar, which is the
operation hole of the gallbladder clamp.

● Second auxiliary hole: Cut the 5mm incision on the front line and under the costal margin, insert a 5mm trocar, and the
first assistant can help expose the surgical field through this hole.

● In the abdominal cavity, the liver and gallbladder triangles are clearly dissected. The cystic duct and cystic artery can be
separated in the triangle of the gallbladder. The hemorrhage of the cystic artery is severed by the clamp.

● can simulate gallbladder peeling during surgery, feel real, and gallbladder bile leakage.

● The skin is removable for easy replacement and can be operated many times.
