Operating table with articulated block
First Claim
1. An operating table comprising:
- a patient support;
a block for supporting a patient'"'"'s lower back which is moveable in relation to the patient support between a retracted position and a deployed position;
an actuator having a first end portion linked to the patient support; and
at least one mechanism for adjusting the block between the retracted and deployed positions comprising a first connecting rod having an end portion pivotally affixed to the patient support, the connecting rod being connected to a second end portion of the actuator for angular displacement and to the block for displacement of the block between the retracted position and the deployed position, and wherein the adjustment mechanism essentially rectilinearly displaces the block between the retracted position and the deployed position.

Abstract
An operating table including a patient support; a block for supporting a patient'"'"'s lower back which is moveable in relation to the patient support between a retracted position and a deployed position; an actuator having a first end portion linked to the patient support; and at least one mechanism for adjusting the block between the retracted and deployed positions including a first connecting rod articulatable relative to the patient support, the connecting rod being connected to a second end portion of the actuator for angular displacement and to the block for displacement of the block between the retracted position and the deployed position, and wherein the adjustment mechanism essentially rectilinear displaces the block between the retracted position and the deployed position.
