Abstract: A forceps tip and a pair of biopsy forceps. A forceps tip (200), comprising a forceps tip base (210), a pull rod (220), a first forceps jaw (230), and a second forceps jaw (240). The proximal end of the pull rod movably matches the forceps tip base along a first preset direction. The distal end of the pull rod movably matches the forceps tip base along a second preset direction. By means of the matching between both ends of the pull rod and the forceps tip base, and the limiting function of the forceps tip base on the pull rod, the motion trajectory of the pull rod is defined. Both the first forceps jaw (230) and the second forceps jaw (240) are rotatably connected to the pull rod (220). The first forceps jaw and the second forceps jaw are driven by the pull rod to move relative to the forceps tip base. The motion trajectory of the pull rod is fixed; therefore, movements of the first forceps jaw and the second forceps jaw are also correspondingly fixed, thereby ensuring that the position is fixed when the forceps tip is opened, and helping an operator accurately clamp a target tissue.
