Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a cutting device for artificial ligament reconstruction. Background Technology

[0002] The cutting device for artificial ligament reconstruction plays a crucial role in the surgical procedure. Its main function is to precisely cut the artificial ligament tissue to meet the required size and shape specifications for the surgery, facilitating accurate implantation into the corresponding part of the patient's body. This ensures the smooth progress of the artificial ligament reconstruction surgery, helps restore the normal physiological function of the damaged area, and often has specific design structures and operational requirements, improving the efficiency, precision, and safety of the surgery.

[0003] In the medical field, cutting devices are an indispensable part of artificial ligament reconstruction. Based on specific mechanical structures and power drive methods, these devices utilize sharp cutting components to cut artificial ligament materials according to preset cutting trajectories and requirements, trimming them to appropriate lengths and widths to ensure they meet the specific needs of the reconstructed area within the patient's body. This facilitates the successful completion of artificial ligament reconstruction surgery. During use, artificial ligament materials are quite strong and difficult to cut. In existing technologies, medical personnel move the cutting tool back and forth to cut the artificial ligament material. However, this back-and-forth movement of the cutting tool can cause secondary damage to the patient's surgical site. Utility Model Content
