Virtual reality surgical device

A system for use in surgery comprising:

• a central body;
• a visualization system operably connected to the central body comprising:
• at least a first camera, and
• at least one of a pan system or a tilt system;
• a first processor and machine readable memory comprising instructions that when executed cause the first processor to generate images based on information from the at least one camera;
• a head-mounted display for displaying images generated by the first processor;
• a first sensor for tracking at least one of the position in space of the head-mounted display relative to a first reference point or the orientation in space of the head-mounted display relative to the first reference point, wherein at least one of the pan system or the tilt system are configured to adjust the field of view of the camera in response to information from the first sensor about changes in at least one of position or orientation in space of the head-mounted display relative to the first reference point;
• a robotic device operably connected to the central body, wherein the robotic device comprises:
• a first rotational actuator for rotating a first portion of the robotic device with respect to a second portion of the robotic device;
• a first hinged actuator for changing the angle between a third portion of the robotic device and a fourth portion of the robotic device operably coupled to the first rotational actuator;
• a second rotational actuator for rotating a fifth portion of the robotic device with respect to a sixth portion of the robotic device operably coupled to the first hinged actuator;
• a second hinged actuator for changing the angle between a seventh portion of the robotic device and an eighth portion of the robotic device operably coupled to the second rotational actuator;
• a third rotational actuator for rotating a ninth portion of the robotic device with respect to a tenth portion of the robotic device operably coupled to the second hinged actuator;
• a third hinged actuator for changing the angle between an eleventh portion of the robotic device and a twelfth portion of the robotic device operably coupled to the third rotational actuator;
• and
• a surgical end-effector operably coupled to the third hinged actuator;
• a second sensor for tracking a series of changes in a position of a portion of an arm of a user;
• a second processor and machine readable memory comprising instructions that when executed cause the second processor to determine a series of positions and orientations of at least two of the twelve portions of the robotic device in response to the series of changes in the position of the portion of the arm of the user based on the degrees of freedom of a human arm, whereby the determined series of positions and orientations of the portions of the robotic device replicate a human-like motion achievable by the human arm;
• and
• at least one servomotor for adjusting at least one of positions or orientations of at least one of the first rotational actuator, the second rotational actuator, the third rotational actuator, the first hinged actuator, the second hinged actuator, the third hinged actuator, or the surgical end-effector to cause the robotic device to follow the series of changes in position of the portion of the arm of the user according to the determined series of positions and orientations of the at least two of the twelve portions of the robotic device so that at least one of the twelve portions of the robotic device mimics the motion of the arm of the user.
