A suturing instrument for surgical operations having a needle holder with a needle and a shuttle holder with a shuttle is provided with an arrangement for controlling the amount of suturing thread drawn out of a bobbin loaded with the thread. The device includes a grooved flange on the bobbin and a spring-biased braking lever turnable in a housing of the instrument and engageable with a respective groove of the flange to maintain the optimum amount of the thread supplied from the bobbin to the needle and the shuttle and to form up the constant stitches during operation.

A surgical suturing instrument crosses and knots a suturing thread combining a shuttle and the other suturing thread passing through an eye of a curved needle in a lock stitching practice, for accomplishing smooth passage of passing the shuttle through a loop of the needle thread and exact combination of the shuttle thread and the needle thread without getting out the shuttle from a shuttle holder during the suturing operation so as to form sound suturing stitchings every time. The shuttle is accommodated between a shuttle holder and a shuttle claw. The shuttle is formed with a front end portion movable between a guide groove in the shuttle claw and a guide groove in the shuttle holder. The shuttle is further formed with a sharp end for catching a thread loop in the suturing operation.

A suturing instrument for surgical operations is operated by an operator with his one hand. A suturing operation is carried out on a human part to be sutured up by crossing a needle thread and a shuttle thread in a lock stitching formation, the instrument being composed of independent members which are, for use, connected to each other easily, exactly and speedily. The main body of the instrument carrying a needle and a shuttle has an externally operated actuating member which actuates a signal generator incorporated in a connecting arrangement for connecting the main body with the drive part of the instrument, whereby when the drive part is connected to the main body by the connecting arrangement an operator may, by moving the actuating member, activate the drive through the signal generator and set all the parts of the instrument into operating positions.

A suturing instrument for a surgical operation includes a suturing portion having a base, a vertically reciprocating needle holder carrying a needle with an upper thread, a device for supplying a predetermined amount of the upper thread to the needle and a loop taker supported in the base for turnable movement relative thereto and operative for catching a thread loop formed on the needle. The device for supplying the upper thread, the loop taker and the needle holder are activated for sequential operation by a control portion of the instrument which includes a fluid drive device connected to the suturing portion and including a plurality of hydraulic cylinders. The control portion is activated by a manually operated switch which actuates an electric circuit and a switching device operating a plurality of the cylinders for sequentially imparting the reciprocating movements to the needle, the loop taker and the thread supplying device.

A curved needle for use in medical operations includes a grip to be mounted in a suturing machine and a curved portion terminated with a needle eye for receivinga needle. On the outside of the curved portion an elongated groove is formed for guiding a thread toward the needle eye. The groove includes a partially closed portion for preventing the thread from slipping out from the groove.

The present invention provides a printing without margins-enabled image forming apparatus that forms toner image matched to the size and position of the conveyed printing material and suppresses waste toner generation. To accomplish this, the present image forming apparatus includes a printing material detection unit that detects orthogonal direction length, conveying direction length, orthogonal direction position, and conveying direction position associated with the conveyed printing material when a printing without margins is selected by the selection unit. In addition, the present image forming apparatus includes a matching unit which, based on the detected length and conveying position, matches the size of the toner image formed on the printing material to the size of the printing material and matches the formation position of the toner image to the position of the printing material conveyed along the conveying path.

A system for reducing electromagnetic noise generated by common mode currents in electrical connections of a power inverter and battery in an electric or hybrid electric vehicle. A pair of spaced apart electrical conductors extends along the vehicle chassis and electrically connects the power inverter to the battery. An electrically conductive metal plate is positioned in between the spaced apart electrical conductors. This metal plate is electrically connected to the chassis adjacent at least both of the power inverter and the battery/motor. Besides this, more connecting points are required to keep the distance between two points less than half wavelength of the maximum frequency of EMI requirements, and most preferably this metal plate is electrically connected to the chassis all the way with infinite connecting points. The metal plate is positioned so that the metal plate is closer to the electrical conductors than the space in between the electrical conductors and the vehicle chassis.
