Multi articulating robatic instrument
View Patent ↗A system for navigating around healthy organs to reach a desired site of surgery is provided. The system includes an articulating shaft capable of navigating around healthy organs in a body. The articulating shaft includes a plurality of shaft sections and one or more movable joints. Further, the one or more movable joints have a two-degree of freedom motion. The two-degree of freedom joints operatively connect the plurality of shaft sections. Moreover, the system includes one or more cables which aid in controlling the movements of the movable joints. Additionally, the system can include a variety of medical tools located at the tip of a shaft section of the articulating shaft, wherein the medical tool aids in performing the medical activity.
1. A robotic instrument suitable for being used in medical activities, the robotic instrument comprising:
an articulating shaft, the articulating shaft including a plurality of shaft sections, and one or more movable joints operatively coupling the plurality of shaft sections, the one or more movable joints including:
a plurality of double helix sections, configured to move in one degree of freedom of motion, the one or more movable joints configured to move the shaft sections with at least two degrees of freedom of motion, the plurality of double helix sections further including a plurality of bumper and socket arrangements, wherein a helix of the plurality of double helix sections comprises one or more holes, the one or more holes acting as a guide for one or more cables, the one or more cobles facilitating movement of the one or more movable joints; and
at least one medical tool, the at least one medical tool attached to a distal end of the articulating shaft.
2. The robotic instrument according to claim 1 , wherein the one or more holes are located at one or more coil turns of a helix of the plurality of double helix sections.
3. The robotic instrument according to claim 1 , wherein the one or more movable joints are made of at least one of a 17-4PH stainless steel, a titanium alloy, a carbon fiber, a biocompatible material, a biocompatible nylon, and a plastic.
4. The robotic instrument according to claim 1 , wherein the medical tool is at least one of forceps, scissors, a needle driver, and an imaging device.
