Permanent brachytherapy with 198Au grains for oral cancer can reduce the burden of patients. Since surgeons insert the radiation source by hand, they are exposed to radiation during the brachytherapy operation. To reduce the radiation exposure, we developed a remotely operated brachytherapy system previously. The system has a remotely insertion device and a gripper. The gripper needs to open the mouth and shift the gripping place. In addition, oral organs have slippery and flexible surfaces. In this paper, we produced a new type of sucker for the gripper. The sucker has balloon bellows that can transform its surface passively. It can grasp a flexible and slippery object as a human oral organ with no slip.
