Title: MEDICAL DEVICE RETAINING APPARATUS
Abstract:
In order to reduce the size of a supporting apparatus through use of a mechanism whereby a load can be supported even when the range of motion of a counterweight is small, a medical device retaining apparatus 100 has a first arm mechanism 3 having a retaining part 2 at a distal end thereof for retaining a medical device E, a second arm mechanism 4 for rotatably connecting a proximal end of the first arm mechanism, a base 6 having a support column 5 rotatably connected to the second arm mechanism and provided upright in the vertical direction, and a first counterweight part 12 connected to a proximal-end part of the second arm mechanism, the second arm mechanism having a support point 4b rotatably connected to the support column, and the first counterweight part having a slit 13 for guiding the proximal-end part of the second arm mechanism when the second arm mechanism is rotated at the support point, the slit 13 being connected to the proximal-end part of the second arm mechanism, and a guide part 15 for receiving a force generated when the proximal-end part of the second arm mechanism is guided by the slit and moves, and causing the first counterweight part to move in the vertical direction.
