Patent number: 9399300Abstract: In one embodiment of the invention, a patient side-system is provided that includes a column with a rail and a counterbalance subsystem. The patient side-system may further include a braking subsystem. The counterbalance subsystem includes a spring assembly coupled at one end to the column with a spring member, and a housing movably coupled to the rail. The housing includes a drum to receive the spring member and a plurality of roller elements to guide a movement of the spring member winding or unwinding on the drum. If present, the braking subsystem includes a first pulley rotatably coupled to the column, a second pulley with a locking mechanism spaced apart from the first pulley and rotatably coupled to the column, and at least one brake cable wrapped around the first pulley and the second pulley with ends coupled to the housing. The locking mechanism can set a position of the housing along the column.Type: GrantFiled: August 31, 2015Date of Patent: July 26, 2016Assignee: Intuitive Surgical Operations, Inc.Inventors: Randal P. Goldberg, Henry Hazebrouck, Dean Hoornaert, David Lidgey
