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 ( 433 a ) 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.
