[0036] Specifically, the working process or principle of this surgical retractor for hepatobiliary surgery is as follows: During use, the hand-held support rod 6 moves the auxiliary hook rod 3 and hook plate 4, and the support rod 6 moves into the support groove 5, so that the rear side of the support rod 6 contacts the front side of the connecting frame 9. The hand-held support rod 6 then moves the insertion port 19. When the insertion port 19 aligns with the connecting frame 9, the connecting frame 9 enters the connecting port 8 through the insertion port 19. The hand-held support rod 6 is then moved to make the connecting frame 9 and the insertion port 19 misaligned, thus connecting the support rod 6 and the support groove 5. Subsequently, the hand-held support rod 6 moves the auxiliary hook rod 3 towards the main hook rod 2. At this time, the connecting frame 9 slides out of the connecting port 8 from the left side. Simultaneously, the limiting plate 7 limits the movement between the support rod 6 and the support groove 5. The base 1, in conjunction with the support rod 6, moves the main hook rod 2 and the auxiliary hook rod 3, inserting the hook piece 4 into the surgical tissue. The support rod 6 is moved according to the actual surgical needs, moving the auxiliary hook rod 3 to adjust the distance between the hook pieces 4. The support is then applied to the surgical tissue. Next, the positioning column 11 is held to move the baffle 15 downwards, disengaging the baffle 15 from the baffle groove 16 and into the positioning groove 12. The moved support rod 6 is then inserted into the base 1 for positioning, ensuring the support rod 6 provides stable support for the auxiliary hook rod 3 and the hook piece 4 during operation. Simultaneously, the magnetic cylinder 17, through the stabilizing column 13, stabilizing hole 14, and magnetic ring 18, magnetically positions the positioning column 11, ensuring the stability of the support provided by the auxiliary hook rod 3 and the main hook rod 2 with the hook piece 4 to the surgical tissue.
