A trocar sleeve capable of holding an endoscopic camera system and an associated endoscopic camera system are provided. When integrated with the trocar sleeve, the endoscopic camera can be used to provide a panoramic overview of the surgical area to supplement the view provided by a main endoscopic camera. The trocar sleeve includes a tube and a base coupled to the tube. The tube includes a channel for accommodating a surgical tool, such as a trocar. The tube further includes a receptacle separate from the channel, for allowing removable attachment of an endoscope to the trocar sleeve. The base includes a fastener for allowing removable attachment of an endoscopic camera head to the trocar sleeve. The camera head has a corresponding fastener for mating with the fastener of the base.

Endoscopic camera system integrated with a trocar sleeve

An endoscopic camera system includes zooming capability to non-mechanically enlarge images of internal features of a body during an endoscopic procedure. The system includes a scope for insertion into the body, a camera head coupled to the scope, and a camera control unit coupled to the camera head. Video image data of internal features of the body are acquired through the scope by the camera head and transmitted to the camera control unit, which generates video images for display on a monitor. The camera control unit includes zoom circuitry for digitally zooming the video images in real-time. Operation of the zoom circuitry may be controlled by manual input or by voice commands. Voice commands may be used to set and recall preset zoom views.
