  • 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.

  • Publication number: 20120277121
    Abstract: A kit for use in a method for detecting live cells, injured cells and dead cells of a microorganism in a test sample by a nucleic acid amplification method is disclosed. The kit includes a cross-linker capable of cross-linking DNA by irradiation with light having a wavelength of 350 nm to 700 nm, medium, and a primer (s) for amplifying a DNA target region in the microorganism by a nucleic acid amplification method. The nucleic acid amplification method may be a PCR, LAMP, SDA, LCR or DNA microarray method. A cross-linker may be included in the kit such as ethidium monoazide, ethidium diazide, psoralen, 4,5?,8-trimethyl psoralen, or 8-methoxy psoralen.
