Abstract
A camera and drape assembly for use with tracking elements of a surgical system includes a camera unit and a drape covering the camera unit. The camera unit includes a casing presenting a face for facing the tracking elements. Optical sensors are supported by the casing and are exposed through the casing for detecting the tracking elements. The drape covers the camera unit such that light signals from the tracking elements can be received by the optical sensors.
Claims16
A camera and drape assembly for use with a tracking element of a surgical system, said assembly comprising:
- a camera unit including a casing and an optical sensor supported by said casing for detecting the tracking element;
- a drape including a first section having a first elasticity and a second section surrounded by said first section and having a second elasticity greater than said first elasticity;
- and
- said casing presenting a lip with said second section configured to extend around and elastically engage said lip to support said drape over said optical sensor so that said optical sensor is capable of receiving light from the tracking element through said second section.
A surgical drape for use with a camera unit having a casing, an optical sensor supported by the casing, and a lip, said drape comprising:
- a first section having a first elasticity and a second section surrounded by said first section and having a second elasticity greater than said first elasticity;
- and
- said second section configured to extend around and elastically engage the lip of the camera unit to support said drape over the optical sensor so that the optical sensor is capable of receiving light from a tracking element through said second section.
A camera and drape assembly for use with a tracking element of a surgical system, said assembly comprising:
- a camera unit including a casing and a plurality of optical sensors supported by said casing for detecting the tracking element, said casing including a base and a post extending upwardly from said base;
- a drape having a flexible section for draping over said post of said casing to cover said casing and said optical sensors;
- and
- a collar sized for fitting over said post to trap said flexible section of said drape between said collar and said post.
