Surgical auxiliary device

Abstract

A surgical auxiliary device includes a host body, an active mechanical arm and two passive mechanical arms. The active mechanical arm is installed on top of the host body. The two passive mechanical arms are respectively disposed at lateral sides of the host body. The position of the highest point of each of the passive mechanical arms at a passive initial posture is lower than the position of the lowest point of the active mechanical arm at an active initial posture.

Claims

1. A surgical aid device, comprising: A base body having a reference plane on its top; an active robotic arm disposed on the base body; Two passive robotic arms are respectively disposed on both sides of the base body. Each passive robotic arm includes a base, a first arm, a second arm, and a third arm. The first arm is connected to the top of the base, and the base is connected to the side of the base body. The second arm is connected between the first arm and the third arm. The first arm rotates along a fourth rotation axis, which is coaxial with the fourth rotation axis and perpendicular to the reference plane. The second arm rotates along a fifth rotation axis, which is coaxial with the fifth rotation axis and perpendicular to the fourth rotation axis. The highest point of each passive robotic arm in a passive initial posture is lower than the lowest point of the active robotic arm in an active initial posture. In the passive initial posture, the second arm of each passive robotic arm is folded and parallel to the lower part of the third arm.

2. The surgical aid device as claimed in claim 1, wherein, The lowest point of the active robotic arm in the active initial posture is above the reference plane, while the highest point of each passive robotic arm in the passive initial posture is below the reference plane.
