The invention discloses a meniscus suture needle and a meniscus suture system and relates to the technical field of medical instruments. The meniscus suture needle comprises a needle rod, the front section of the needle rod is warped in a curved arc shape and gradually becomes smaller along with forward extension to form a needle tip, the needle rod is of a hollow structure, a notch is formed in the front section of the needle rod, the notch expands and becomes larger inwards from the surface of the needle rod, so that a barb part capable of hooking a pull suture is formed at the notch, the notch is communicated with an inner cavity of the needle rod, a hook tip of the barb part faces the rear portion of the needle rod, the rear section of the needle rod is connected with a handheld part convenient for a hand to grab, a first fixing part for fixing one end of a suture and a second fixing part for fixing the other end of the suture, when the meniscus suture needle is used, a suture linecan penetrate into the inner cavity of the needle rod from the rear end of the needle rod and penetrates out of the notch, and then the two ends of the suture line are fixed through the first fixingpart and the second fixing part respectively. The meniscus suture needle has the advantages of being more convenient to use, higher in operation efficiency, better in suture effect and higher in clinical application and popularization value.
