Hand-actuated articulating surgical tool
First Claim
1. A surgical device, comprising:
- at least one controller located at a proximal end of the surgical device, said controller being adapted to transmit hydraulic control signals;
at least one manipulator, said manipulator being configured to be controlled by a human hand and to actuate said controller;
at least one slave located at a distal end of the surgical device, said slave being in fluid communication with said controller and being configured to respond to said hydraulic control signals transmitted by said controller; and
at least one control line providing hydraulic communication between said controller and said slave;
wherein said slave directly or indirectly causes the operation of, or the change of position of, a tool necessary for performing a surgical procedure.
