Description

Technical Field

[0001] The utility model relates to the technical field of surgical instruments, in particular to a traction device for cystic echinococcosis lesions of the liver used for laparoscopic and laparotomy surgeries. Background Art

[0002] Cystic echinococcosis requires surgical treatment. The cysts are often huge, with a diameter of more than 5 cm or even more than 10 cm, and are located deep, making them difficult to expose during surgery. This affects the treatment effect and may make it impossible to perform radical surgery, resulting in complications such as postoperative recurrence and bile leakage.

[0003] The cyst is enlarged and has a relatively smooth surface. There is no support point for traction and exposure. If sutures are used, the cyst fluid may overflow and spread along the needle hole, and the thin sutures may cut the cyst wall and cause rupture. Based on this, the utility model proposes a traction device for cystic hydatid lesions of the liver for laparoscopic and open surgery. Utility Model Content
