  • Publication number: 20240341737
    Abstract: Disclosed are a method and control device for adjusting an opening size of a sampling window of a biopsy surgical device. The biopsy surgical device includes a motor, an outer cutter tube and an inner cutter tube. The outer cutter tube includes a sampling window on a side of the front end. The motor drives the inner cutter tube to move axially through a transmission mechanism, changing the axial relative position of the inner cutter tube and the sampling window. The method includes: obtaining an input instruction that includes a set value of an sampling window opening length; determining an axial movement distance of the inner cutter tube according to the current position of the inner cutter tube and the set value; calculating the number of rotations of the motor corresponding to the axial movement distance; and controlling the motor to rotate until the sampling window reaches the opening length.
