Abstract
A medical device holding apparatus having a first arm with a holding portion to hold a medical device; a second arm connected to the rotatable first arm; a base connected to the rotatable second arm and having a support shaft standing in a vertical direction; and a first counterweight portion connected to the second arm, wherein the second arm has a fulcrum around which the second arm is rotatable, and the first counterweight has a slit being connected to the proximal end portion of the second arm for guiding the proximal end portion of the second arm when the second arm is rotated around the fulcrum; and a guide for moving the first counterweight in the vertical direction after the guide receives a force generated when the proximal end portion of the second arm is guided and moved in the slit.
Claims6
A medical device holding apparatus comprising:
- a first arm mechanism having a holding portion configured to hold a medical device;
- a second arm mechanism connected to the first arm mechanism so as to make the first arm mechanism to be rotatable;
- a base connected to the second arm mechanism so as to make the second arm mechanism to be rotatable, the base having a support shaft standing in a vertical direction;
- and
- a first counterweight connected to a proximal end portion of the second arm mechanism,
- wherein the second arm mechanism has a fulcrum connected to the support shaft, the second arm mechanism being rotatable around the fulcrum, and
- wherein the first counterweight has:
- a slit connected to the proximal end portion of the second arm mechanism, the slit being configured to guide the proximal end portion of the second arm mechanism when the second arm mechanism is rotated around the fulcrum;
- and
- a guide configured to move the first counterweight in the vertical direction after the guide receives a force generated when the proximal end portion of the second arm mechanism is guided and moved in the slit.
