Hand-actuated articulating surgical tool
First Claim
1. A surgical device, comprising:
- at least one controller located at a proximal end of the device, said controller being adapted to transmit hydraulic or mechanical control signals;
at least one manipulator, said manipulator being configured to be controlled by a human hand and to actuate said controller by mechanically transmitting control signals from the manipulator to the controller;
at least one slave located at a distal end of the device, said slave being configured to be inserted into the body of a patient and to respond to said hydraulic or mechanical control signals transmitted by said controller and said slave including a surgical tool; and
a control line configured to extend inside the body of a patient and to provide said hydraulic or mechanical control signals between the controller and the slave,wherein movement of the surgical tool is caused directly by the force applied to the manipulator.

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.

24. A surgical device, comprising:
-
a controller located at a proximal end of the device, said controller being adapted to transmit hydraulic control signals; a slave located at a distal end of the device, said slave being configured to be inserted into the body of a patient and to respond to said hydraulic control signals transmitted by said controller, said slave including a bend module; and a control line extending between the controller and the slave providing said hydraulic control signals between the controller and the slave, wherein the bend module includes a spring bar and a plurality of pouches in hydraulic communication with the control line, and wherein the plurality of pouches are configured to cause the spring bar to bend as hydraulic fluid enters the pouches. - View Dependent Claims (25, 26)
