The invention discloses an easy-to-clean and easy-to-dismantle laparoscopic machine probe used for the hepatological surgery department. The probe includes a connection head, the connection head is internally provided with two placement grooves, the inner side walls of the two placement grooves are provided with triangular clamping grooves, matched triangular clamping blocks fits the insides of the triangular clamping grooves, the triangular clamping blocks are fixedly arranged at one ends of slide rods, the slide rods are sleeved with sliding sleeves, and the sliding sleeves are clamped in grooves formed in the outer side wall of a sleeve; when a probe part needs to be partially dismantled, the two slide rods are driven through moving rods and connection rods to come close to each other by pressing two pressing blocks, the two slide rods come close to each other and drive the two triangular clamping blocks to be disengaged from the triangular clamping grooves, and after the triangularclamping blocks are completely disengaged from the triangular clamping grooves, the two triangular clamping blocks can be in the grooves. At this moment, the dismantling of the connection head and the probe part can be completed, separate dismantling can be achieved during subsequent cleaning, and convenience is brought to the cleaning operation.
