The present invention relates to a tenaculum comprising a suction head and a handle part connected to each other by a suction tube, the handle part comprising a vacuum pump. The vacuum pump comprises a vacuum tank comprising a first opening at its first end and a second opening at its second end, wherein the suction tube is connected to the first opening； a spring； means for compressing the spring； and a piston. The piston comprises a piston head moveably arranged within the vacuum tank； an axle having a first end and a second end, its first end being connected to the piston head and its second end being connected to the means for compressing the spring； and a pressure seal arranged on the piston head to isolate a vacuum space of the vacuum tank from the second opening. The spring is arranged to move the piston head.本發明係關於一種持鈎，其包括藉由一吸管所彼此連接之一吸頭及一柄部，該柄部包括一真空泵。該真空泵包括：一真空槽，其第一端處包括一第一開口且其第二端處包括一第二開口，其中該吸管連接至該第一開口；一彈簧；用於壓縮該彈簧之構件；及一活塞。該活塞包括：一活塞頭，其可移動地配置於該真空槽內；一軸，其具有一第一端及一第二端，其第一端連接至該活塞頭且其第二端連接至用於壓縮該彈簧之該構件；及一壓力密封件，其配置於該活塞頭上以將該真空槽之一真空空間與該第二開口隔離。該彈簧經配置以移動該活塞頭。
