An MPEG2 MP@ML video encoder large-scale integrated circuit (LSI) has been developed including an 81 MOPS controller and motion estimator. By using two adaptive algorithms, a wide motion-estimation search area ( 288 pixels horizontal and 96 pixels vertical) was achieved with computation complexity of only 0.5% (20 GOPS) of full search blockmatching(More)
During endoscopic surgery, all surgical manipulation should be performed through a limited number of fixed ports, which contributes to the difficulty associated with laparoscopic surgery. Especially in colorectal resection, many bowel clamps have been required to hold the large intestine [1]. Therefore, we developed a new retractor that is sufficiently fine(More)
The present paper introduces a new fine probe for electric cautery (1.65 mm in diameter, 22 cm long) that can be connected to a conventional cylindrical hand-controlled cautery holder, which is monopolar and widely used in general surgery. When cautery was required, a 14-gauge intravenous catheter was inserted at an appropriate site under the guidance of a(More)
