AI Technical Summary
Technical Problem
In current laparoscopic surgeries, the irregular shape of the lesion tissue makes it difficult to wrap the retrieval bag, leading to difficulties in removal and potentially increasing surgical trauma and infection risks.
Method used
A malleable laparoscopic specimen retrieval bag was designed. The bag has a spiral channel and a pull rope inside. By pulling the rope, the bag can be contracted to wrap the lesion tissue. The side walls are staggered with concave and convex parts to adapt to different shapes and achieve the elasticity of the bag.
Benefits of technology
This method successfully removed the lesion tissue, reduced surgical trauma and infection risk, and improved surgical safety.

Abstract
This utility model discloses a malleable laparoscopic specimen retrieval bag, including a bag body with an internal chamber for holding the specimen. The upper end of the bag body is open, and the side wall of the bag body has a spiral channel with a pull rope inside. One end of the pull rope is fixed to the bottom of the bag body, and the other end of the pull rope extends through the upper end of the bag body to the outside. The side wall of the bag body has multiple recesses and protrusions. In this utility model, after the lesion tissue in the patient's body is removed during laparoscopic surgery, the retrieval bag is placed into the abdominal cavity via a trocar, and the lesion tissue is placed into the chamber of the bag body. Due to the strong malleability of the bag body, the bag body can be contracted by pulling the pull rope, and the bag body can completely wrap the lesion tissue, making it easy to remove the retrieval bag from the incision and avoiding secondary damage to the patient caused by enlarging the incision. At the same time, the side wall of the bag body has recesses and protrusions, so the bag body can be compressed and folded, and has a certain degree of shrinkage performance.
