A method is described for using percutaneous access to a patient to remove an object from a cavity within the patient. The method includes inserting a suction tube into a port created by a percutaneous cut. An endoscope is also advanced into the cavity, however the endoscope passes through a patient lumen rather than through the port. Using a working channel within the endoscope, fluid is irrigated through the cavity. Additionally, a negative pressure is applied to the suction tube, such that the combination of fluid irrigation and negative pressure assist in removing the object from the cavity through the suction tube.

A protective helmet apparatus of modular construction to be worn by anesthetized patients for facial support during surgery. The helmet apparatus is assembled using one of a plurality of interchangeable, substantially transparent helmet casings, which are removably attachable to a plurality of dismountable facial cushions providing even support to the facial surface of a patient. The removable facial cushions are dimensioned on and interior surface to accommodate different sized facial structures of different patients to yield maximum pressure diffusion on the face and chin of the patient and are replaceable when worn. The exterior surface of the facial cushions are dimensioned for cooperative engagement with the interior surface of the helmet casing. A plurality of different facial cushions and helmet casings are modular in design and dimension to be interchangeable with each other thus providing accommodate the broad differences in facial structure and size of patients using them for surgery.

A unitary support for holding and cushioning the head and face of a surgical patient has a resilient body of molded foam. The resilient body has a cavity formed in the upper face for receiving and cushioning the head and face of a patient. The resilient body has access openings therein for additional apparatus, such as an endotracheal tube, and to permit viewing of the patient's face during surgery. The resilient body has stiffening structure to prevent constriction of the openings during use and to prevent constriction of an endotracheal tube or similar apparatus.

A system for maintaining a height adjustable patient bed in a level position while adjusting height of the bed is provided. The system has electrically powered linear actuators having internal position sensors, the linear actuators operable to adjust the height of the bed. The system also has control means, electrically coupled to the linear actuators, which compares position information from the internal position sensors and then adjusts the power supply to one or the other of the linear actuators in response to the position information. This permits the trailing linear actuator to catch up to the lead linear actuator to maintain the bed in a level position while the height of the bed is being adjusted. Since the internal position sensors work on small changes in position, the leveling effect is not noticeable leading to less tilt of the bed and a smoother motion during height adjustment of he bed.
