Patent number: 11950821Abstract: A surgical tool for positioning a surgical device includes a gripping portion; a rod protruding from the gripping portion; and a coupling system. The coupling system comprises an axial retention assembly comprising, at a free end of the rod, two opposite semispherical portions, wherein respective flat surfaces are separated from each other by an axial notch made partially along the rod, and a central clutch movable between a locking position and a disengagement position. In the locking position, the central clutch approaches the free end of the rod and is interposed between the two semispherical portions, preventing reciprocal approach thereof so as to block the two semispherical portions within a seat of said surgical device. In the disengagement position, the central clutch moves away from the free end such that the two semispherical portions can approach to allow the tool to come out of the surgical device.Type: GrantFiled: November 21, 2019Date of Patent: April 9, 2024Assignee: Medacta International SAInventors: Takashi Kaito, Keitaro Matsukawa, Geert Mahieu, Ralph Mobbs, Yuichiro Abe, Meinrad Fiechter, Francesco Siccardi, Gianluca Milano
