Auxiliary instrument for nephron-sparing surgery under laparoscope

The utility model belongs to the technical field of medical apparatuses and instruments, and provides an auxiliary instrument for nephron-sparing surgery under a laparoscope. The auxiliary instrument for the nephron-sparing surgery under the laparoscope is composed of a kidney binding band (1), a hoop (2), a connecting rod handle (3), a hoop clamping sheet (4), a self-locking pulling sheet (5), a self-locking sliding block (6), a sliding block clamping sheet (7) and a movable handle (8). The auxiliary instrument for the nephron-sparing surgery under the laparoscope can only block blood supply of the kidney at a tumor growth end by controlling the kidney binding band (1), the effect of tumor cutting is guaranteed, blood loss volume in the surgery is lowered, more importantly, ischemia time of the remained part of the kidney is reduced to zero, the situation that the blood supply of the whole kidney is blocked is avoided, the function of the remained kidney is protected to the maximum extent, and the significance of the nephron-sparing surgery under the laparoscope is embodied fully.
