Hand-actuated articulating surgical tool
First Claim
1. A double cylinder system, comprising:
- at least one controller being adapted to transmit hydraulic control signals, said controller further comprises;
a control cavity; and
a first piston within said control cavity, said first piston dividing said control cavity into a first control cavity portion and a second control cavity portion and preventing communication between said first control cavity portion and said second control cavity portion;
at least one slave being in fluid communication with said controller and being configured to respond to said hydraulic control signals transmitted by said controller, said slave comprising a slave cavity; and
a second piston within said slave cavity, said second piston dividing said slave cavity into a first slave cavity portion and a second slave cavity portion and preventing communication between said first slave cavity portion and said second slave cavity portion; and
at least one control line providing hydraulic communication between said first control cavity portion and said first slave cavity portion; and
at least one control line providing hydraulic communication between said second control cavity portion and said second slave cavity portion.

Abstract
A double cylinder system is disclosed, comprising at least one controller being adapted to transmit hydraulic control signals; at least one slave being in fluid communication with the controller and being configured to respond to the hydraulic control signals transmitted by the controller; and at least one control line providing hydraulic communication between the controller and the slave. Also disclosed is a surgical device, comprising at least one controller located at a proximal end of the device, the controller being adapted to transmit hydraulic control signals; at least one manipulator, the manipulator being configured to be controlled by a human hand and to actuate the controller; at least one slave located at a distal end of the device, the slave being in fluid communication with the controller and being configured to respond to the hydraulic control signals transmitted by the controller; and at least one control line providing hydraulic communication between the controller and the slave.
