Suspension apparatus for operating room microscope
First Claim
1. Suspension apparatus for rotatably supporting an operating room microscope comprisinga C-shaped suspension arm having a central portion, an end portion disposed at a substantially right angle to the central portion and suspension arm coupling means disposed at said end portion, andmicroscope coupling means comprising a first swivel joint having a first female member which includes a bore disposed therein at an angle of from about 140°
- to about 160°
from the vertical with reference to the mounted position of said first female member, said bore being adapted to rotatably receive a shaft which is connected to a member which is pivotably connected to the microscope,said suspension arm coupling means rotatably coupling said microscope coupling means to said end portion and comprising a second swivel joint having a second female member and a male member, one of said second female member and said male member being disposed at said end portion of said suspension arm and the other of said female member and said male member being connected to said first female member of said first swivel joint,whereby the microscope is adapted to being rotated in the vertical plane at angles of up to from about 140°
to about 160°
between the vertical and the axis of vision of the microscope.

Abstract
A suspension arm and couplings are disclosed for supporting an operating room microscope. The suspension arm and couplings permit rotation of the microscope in the vertical plane up to angles of from about 140° to about 160° between the axis of vision of the microscope and the vertical. In the disclosed embodiment, the suspension arm is a one-piece C-shaped configuration provided with swivel joint couplings at each end thereof. One of the swivel joint couplings rotatably connects the C-shaped suspension arm to the remainder of a suspension system and the other swivel joint coupling suspends still another swivel joint coupling to which is connected the microscope. The swivel joint coupling connected to the microscope has a female part with a bore extending non-centrally therethrough for receiving the male part, a shaft, of a C-bracket which rotatably supports the microscope. The bore is disposed in the female part at an angle of from about 140° to about 160° from the vertical with reference to the mounted position of the swivel joint coupling.
