  • Patent number: 8021376
    Abstract: An endoscopic treatment device is used with an endoscope. This treatment device includes a transmission member with a flexible structure having a distal end portion to be inserted into a body and can be operated outside the body, a push rod coupled to the distal end portion, and first and second connecting members rotatably coupled to the push rod. The treatment device further includes first and second arm members rotatably coupled to the distal end portion of the connecting member, a holding member rotatably holding the respective arm at a predetermined interval therebetween, and first and second actuating members integrally formed with the arm members and can open/close when the transmission member actuates the first and second connecting members and the first and second arm members through the push rod. This device also includes a needle mounted on at least one of the first and second actuating members.

  • Patent number: 7175636
    Abstract: An endoscopic suturing instrument is equipped with a needle mounted at the distal end of the suturing instrument for the purpose of living-tissue punctures. An engaging mechanism is provided at least at the distal end of the needle for the purpose of connecting the thread while allowing it to move freely, and the suturing instrument includes a needle-driving mechanism to drive the needle. A loop-creating mechanism is used to create a first loop in the thread, by loosening the thread connected to the engaging mechanism. A catching mechanism is provided at the distal end of the suturing instrument to be inserted through the first loop to catch the thread. The thread caught by the catching mechanism can be moved freely. The needle-driving mechanism and the catching mechanism are mechanically coupled.
