Abstract:
Provided is a bionic surgical instrument, comprising: an instrument rod (10); a functional portion (20) provided at a distal end of the instrument rod (10); and a hand-held portion (30) provided at a proximal end of the instrument rod (10), the hand-held portion (30) transmitting a control action of the hand-held portion (30) to the functional portion (20) via a transmission component (40). A first reference ray (R1), collinear with or parallel to a central axis of the hand-held portion (30) and in a first direction, is made with the proximal end (A) of the instrument rod (10) as a vertex, and a second reference ray (R2), collinear with or parallel to a central axis of the instrument rod (10) and in a second direction, is made with the proximal end (A) of the instrument rod (10) as a vertex, and an included angle between the first reference ray (R1) and the second reference ray (R2) is greater than zero degrees and is less than or equal to 90 degrees, wherein the first direction is the direction from a connection end of the hand-held portion (30) to a free end of the hand-held portion (30), and the second direction is the direction from the proximal end (A) of the instrument rod (10) to the distal end of the instrument rod (10).
