Abstract: A hemostatic clip applicator useful in the rapid and automatic application of hemostatic clips for the strangulation of tubular members is disclosed. The applicator consists of a main body, a clip magazine externally attached to the main body, clip deforming jaws attached to one end of the main body, a laminated clip feed blade located within the clip magazine, and an actuating mechanism attached to the feed blade and deforming jaws. In operation, one of many hemostatic clips stored in the clip magazine is fed into the deforming jaws by the interaction of the actuating mechanism and the feed blade. This feeding of a hemostatic clip into the deforming jaws is a result of the clip feed means engaging a clip from the clip magazine, sliding into the deforming jaws so as to move that clip into the deforming jaws, and the retracting of the clip feed means from the deforming jaws.

Abstract: A control section consisting of an address processing circuit and two sequencers for use in a programmable microprocessor. The address processing circuit has two sets of input lines and one set of output lines, and is adapted to convert address information provided at the input lines into a signal at the output lines which consists of microinstructions suitable for use in other portions of the microprocessor. Each sequencer is connected to one set of input lines of the address processing circuit and is adapted to receive data from an external source and provide address information corresponding to such data to the address processing circuit. In operation, the signal provided at the output lines of the address processing circuit consists of time-division multiplexed microinstructions, each such microinstruction being derived from one of the two external sources.

Abstract: A hemostatic clip applicator useful in the rapid and automatic application of hemostatic clips for the strangulation of tubular members is disclosed. The applicator consists of a main body, a clip magazine externally attached to the main body, clip deforming jaws attached to one end of the main body, a clip feed mechanism located within the main body and an actuating mechanism attached to the feed mechanism and deforming jaws. In operation, one of many hemostatic clips stored in the clip magazine is fed into the main body and guided to the deforming jaws by the interaction of the actuating mechanism and the feed mechanism. When the clip is properly located about a tubular member, further actuation of the actuating mechanism results in the deformation of the clip about the tubular member.

Abstract: An ultrasonic scanner for use in medical diagnosis which produces two different types of scans. The scanner includes a housing carrying one or more ultrasonic transducers which traverse an arcuate path. A first reflector is positioned within the arcuate path to intercept ultrasonic waves and converge them at a point beneath the scanner in order to produce a skin centered sector scan, which is useful for viewing through small acoustic windows such as intercostal regions. A pair of reflectors, one of which is positioned horizontally with respect to the first reflector and the transducers, are utilized to form a wide aperture sector scan which diverges upon exiting the scanner housing. The wide aperture scan is useful for scanning spaces such as the abdomen which include relatively few obstructions.
