摘要： A puncture instrument kit includes a puncture rod, mesh, and sheath. The puncture rod consists of a puncture head, puncture rod body, and handle. One end of the puncture rod body is connected to the handle and the other end is integrated with the puncture head. The puncture head is arc-shaped with an end gradually tapering to form a tip. The tip of the puncture head is circumferentially designed with a groove for fixing a thread during surgery. The puncture head is smoothly connected with the puncture rod body, and the line between the tip of the puncture head and puncture rod body is at an obtuse angle of 130-140° relative to the puncture rod body. The sheath is sleeved on the puncture rod with the rod tip exposed. The mesh and sheath are designed as separate or integrated, and the tip of the puncture rod is provided with a shape-matching detachable silicone protective sleeve.
