tion which is mounted on the vibration generator (10). The medical treatment apparatus further includes a cover member (20) for surrounding the outer surface of the vibration transmission member (16) and an exposing member (21) for exposing the distal end portion of the vibration transmission member (16) outside the cover member (20). When the vibration transmission member (16) is inserted into an endoscope channel and a body cavity, the distal end of vibration transmission member (16) does not damage them since the distal end is sealed with the cover
M E D I C A L E X A M I N A T I O N TABLE WITH PROBE HOLDER Gwendolyn J Stewart, Marvin Ziskin, Charles Philips, Philip Alburger, John W Lachman, Donald W Manuel, Michael Troisi assigned to Temple University of the Commonwealth System of Higher Education A method of predicting the occurrence of deep vein thrombosis after a surgical procedure comprises monitoring changes in the internal diameter of a blood vessel using a non-invasive ultrasound technique. The frequency and magnitude of changes in vessel diameter are used to predict whether deep vein thrombosis will occur.

4867141 MEDICAL TREATMENT APPARATUS UTILIZING ULTRASONIC WAVE
Apparatus for simulating inspection equipment, e.g. ultrasonic N D T equipment or ultrasonic medical diagnostics equipment, comprises a test body, a simulated probe for scanning over the body, a probe position monitor, inspection data storage, a display and a central processor for correlating display of the inspection data with scanning movement of the probe. The inspection data is derived from non-simulated scanning of for example a structure containing defects and the ultrasonic waveforms obtained during such non-simulated scanning may be stored in memory for providing a realistic display during simulated scanning of the test body. The simulated probe may incorporate an ultrasonic device for the purpose of sensing the degree of
Aki Nakada, Syuich T a k a y a m a , Tatsuya Kubota, Tetsumar Kubota, Koji Taguchi, Shinichi Imade, N a o m i Sekino, Tokyo, Japan assigned to Olympus Optical Co Ltd A medical treatment apparatus utilizing ultrasonic waves according to this invention is applied to treatments such as breaking up a stone formed in a living body. The medical treatment apparatus utilizing ultrasonic waves includes a vibration generator (10) for generating ultrasonic vibrations and a vibration transmission member (16) for transmitting the ultrasonic vibrations generated by the vibration generator (10). The vibration transmission member (16) has a front end portion and a proximal end por845
