Summary:The invention relates to a biopsy capsule capable of achieving back-and-forth different trace control through the same swing control mechanism. A quadrilateral mechanism is driven by a lead screw nut system to move and deform. And a swing control mechanism is combined with a screw-nut system to control the movement or deformation of the quadrilateral mechanism, so that the biopsy function of opening (discharging), stretching, sampling, closing and retracting back and forth for different traces of the pair of detection pliers is realized. The posture control seat can actively control the posture of the capsule, the swing control mechanism is matched with the biopsy motor to drive the detection forceps to stretch, retract, move and swing in an opening and closing mode, the multiple biopsy functions of entering and exiting different traces are achieved, a series of actions of moving, stopping, sampling and discharging of the detection forceps are finally completed, and the capsule can be taken by one-time swallo
