Furthermore, an observation seam is arranged between the movable tong head and the fixed tong head, and the shape of the through hole on the clamping part is similar to the shape of the outer contour of the clamping part.
Furthermore, the movable handle and the fixed handle both comprise a connecting rod and a handheld ring arranged at the outer end part of the connecting rod, and one side of the connecting rod, which is close to the handheld ring, is provided with locking teeth.
Furthermore, the outer surface of the hand-held ring is covered with a layer of soft rubber sleeve.
Furthermore, the front end of the clamping parts is triangular, the height of the clamping parts is 5mm, and the distance between the outermost sides of the two clamping parts is 9.5 mm.
Further, the length of the lymph node forceps body is 330mm, and the height of the lymph node forceps body is 16 mm.
The utility model has the beneficial technical effects that: the utility model has simple structure, accurate adjustment and opening and closing, is favorable for safe operation, the connecting part of the forceps head is of a downward arc structure, the front end of the clamping part of the forceps head is of a triangular shape, and the space of the accommodating cavity in the forceps head is larger, thereby being favorable for grasping the lesion lymph node in a narrow tissue space.
