  • Surgical appliance for use in taking out transplant-use tendon and in regenerating operation of tendon at location where transplant tendon was taken out
    Patent number: 8430896
    Abstract: A surgical appliance for taking out a transplant-use tendon in surgery and assisting reconstruction of the tendon after take out. The surgical appliance has a tendon cutter, guide tube, a grip portion and a guide needle. The guide tube is a hollow thin tube having open opposing ends, wherein a distal end opening constitutes a discharger port of the guide needle. A through hole is formed in the grip portion in the direction of a central axis, and the proximal end side outlet of the through hole constitutes an insertion port. The guide needle is provided with a sharp conical tip on a distal end side and a threading hole on a proximal end. The guide needle is inserted into the guide tube, such that the opposite ends may be exposed from the discharge port and the insertion port when it is inserted into the guide tube.
