Alternatively, as shown in fig. 1, in the case where at least a portion of the first tube 2a extends out of one end of the hollow tube 1, the adsorption modules 2b communicate with the elastic tube 2 in a circular array. In operation, the surgeon extends a portion (e.g., one-half or three-quarters) or all of the first tube 2a out of one end of the hollow tube 1 as needed for the desired tissue to be lifted by the medical practitioner. Since the first tube 2a forms a ring-shaped body after protruding out of one end of the hollow tube 1, the adsorption module 2b communicates with the elastic tube 2 in a ring-shaped array after the first tube 2a protrudes out of one end of the hollow tube 1. The number of the adsorption modules 2b is plural. For example, the number of the adsorption modules 2b is 8 as shown in fig. 1 or 2.
