Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a grasping forceps that is easy to use. Background Art

[0002] With the development of orthopedic sports medicine, rotator cuff repair surgery has received more and more attention and application. Rotator cuff repair surgery is a surgery that uses artificial methods (such as braided wire, suture anchors, etc.) to close the tear of the torn rotator cuff tendon tissue to promote its healing and restore the function of the rotator cuff tissue. Tissue grasping and threading are part of the operation, the purpose is to grasp the tissue and pass the suture through the target tendon. At present, rotator cuff repair surgery generally requires using tissue graspers to grasp the tissue first, and then using a threader to thread the thread, passing the thread through the grasped tissue for suturing.
