  • Patent number: 6428535
    Abstract: A medical apparatus comprising an apparatus body and a terminal instrument which operates when receiving a terminal output which is an electric or electromagnetic output. The terminal instrument is provided with an installed cell of predetermined capacity and the apparatus body is provided with a circuit for measuring the electromotive force (emf) of the installed cell while discharging the emf via a predetermined resistance as the terminal instrument is used. A comparator compares the emf with a standard voltage and the output command is blocked from the primary control section when the emf of the installed cell is below the standard voltage. Moreover, an alarm is generated when the emf of the installed cell is below the standard voltage level during the use of the terminal instrument.

  • Patent number: 6076255
    Abstract: This invention relates to a needle attached suture manufacturing method and apparatus capable of cutting a suture exactly at the same length, with a simple construction and high efficiency. A transport/holding device 42 holds a suture Y and transports the suture straight forward toward a needle swaging device 20 a distance corresponding to a predetermined target value. Thereafter, the suture Y is cut at a certain position to obtain a suture strand. The suture strand is then inserted in an insertion hole formed at the end of a needle and is swaged by the needle swaging device 20. As an altered method, after the suture Y is inserted in the insertion hole of the needle, the suture Y is cut at a position away from the end of the needle a predetermined target distance.

  • Patent number: 6012603
    Abstract: This invention relates to a needle supply device for use in a needle attached suture manufacturing apparatus or its equivalent to automatically supply curved needles one by one to a predetermined position of the apparatus in a state that the needle is accurately set in the same posture. The needle supply device has a passage defining member 32 including a needle storage portion 42, passages 44 and 46, and a needle discharge tray 55 in this order. By driving the passage defining member 32 to vibrate, needles N set on the needle storage portion 42 proceed along the passages 44 and 46 toward the needle discharge tray 55. There are provided selecting units 48, 50, and 52 each in a certain passage form on the way of the passages 44 and 46 to exclusively allow the needles N in the predetermined posture to pass while maintaining the predetermined posture.

  • Patent number: 5943765
    Abstract: An object of this invention is to provide a needle attached suture manufacturing apparatus, with a simple construction and reduced cost, capable of assuredly inserting the lead end of a suture in an insertion hole formed in the end of a needle before the end of the needle is swaged. In order to accomplish the above object, a needle swaging device 20 of this apparatus includes die support members 101 and 102 on which swaging dies 111 and 112 are mounted to be movable toward and away from each other. Suture guide plates 95 and 96 are mounted on the die support members 101 and 102 and are formed with guide grooves 95a and 96b, respectively. Before a swaging operation of the needle end by the swaging dies 111 and 112, the suture guide plates 95 and 96 move to a contact state or to a close contact state with each other when the swaging dies 111 and 112 are set to a pre-swaging position in contact with or in close contact with the end of the needle.

  • Patent number: 5943759
    Abstract: This invention relates to a method for manufacturing a needle attached suture and an apparatus therefor. A needle attached suture is obtained by inserting a suture into an insertion hole formed in the end of a needle N which is held by a needle retaining unit 16 and by swaging the end of the needle with the suture. The method and the apparatus have been developed to accurately position the end of the needle for swaging with the suture to stabilize the swaging strength between the suture and the needle. Before the swaging, the needle is held by the needle retaining unit 16, and the end of the needle N is pushed to a certain position by a rod 99 or its equivalent. Thereby, the end of the needle N relative to the needle retaining unit 16 is accurately positioned.
