A recently granted patent (Publication Number: US11925343B2) discloses a traction apparatus designed for medical procedures, comprising a clip portion and a traction portion. The traction portion features a closed traction structure made of elastic material, capable of eversion during a cutting process to aid in tissue separation. The clip portion includes a main clip body and a clip arm for securing the closed traction structure and a pre-separated nidus. Additionally, a connection ring is integrated into the traction portion to enhance stability by being sleeved on the clip arm.

Furthermore, the patent includes details on the composition and design of the traction apparatus, specifying the use of materials like silicon rubber or thermoplastic elastomer for the closed traction structure. Elastic connection structures are also highlighted, such as elastic linear or ring structures, to facilitate the movement and deformation of the closed traction structures. The patent emphasizes the versatility of the closed traction structure, which can be shaped in various forms like round, triangular, rhombic, or square, to suit different medical applications. Additionally, features like inner thorns on the clip arm and serrated structures for improved grip are detailed to prevent slippage during use, ensuring precise and effective tissue separation.
