Telescopic column assembly in a robotic arm system

Abstract

A telescopic column assembly (213) for docking of a robotic arm at variable height in a robotic assisted surgery is disclosed herein. The telescopic column assembly (213) may include a plurality of spring assemblies (321), a rack and pinion assembly (323), a position sensor (325), and a motor (449). The plurality of spring assemblies (321) may be a constant spring such as (401), (403), (405), (407). The plurality of spring (401), (403), (405), (407) are wrapped to a plurality of drums (417), (419), (421), (423) and other ends of the plurality of springs (401), (403), (405), (407) are secured to a horizontal profile (433a) of the support member (433). The support member (433) is configured to move in vertical directions which is facilitated by the spring assemblies (321), the rack and pinion assembly (323) and the motor (449), to variably adjust the height of the surgical instruments while docking.
