Abstract: A probe cover is provided. The probe cover is formed from a film that defines a tubular sheath having a distal end and a proximal end defining a channel therebetween, where the distal end is closed and the proximal end defines an opening having a periphery; and a flange that extends from the periphery of the opening at the proximal end of the tubular sheath. The flange facilitates the secure attachment of the probe cover to a surgical drape, such as a surgical drape used in the operating room as an anesthesia screen or as a screen to separate the surgical sterile field from the non-sterile field. A method of using the probe cover in conjunction with a probe during a surgical procedure is also provided, where the method includes attaching the probe cover to a surgical drape. A surgical drape that includes the probe cover is further provided.

Abstract: A saw comprises a blade configured to perform a cut on a work piece at a cutting position. The saw includes a measurement device configured to determine a distance. The measurement device includes a laser generator configured to emit a laser beam. A laser interference member is provided on the work piece with a portion of the laser interference member in the path of the laser beam. The laser interference member comprises a reflective surface configured to reflect the laser beam and an adhesive surface configured to adhere to the work piece. A digital display provides an indication of the determined distance. In another embodiment, the measurement device is provided as a sensor wheel associated with the engagement surface. The sensor wheel is configured to rotate when the work piece is moved along the engagement surface and determine a distance the work piece has moved along the engagement surface.
