  • Patent number: 9763651
    Abstract: A tendon stripper includes a stripping device and a rod. The stripping device includes a stripping member and at least one coupling member coupling to the stripping member. The stripping member has a blade portion and a separating portion separating the stripping member into several parts. The rod has a handle end and a coupling end opposite to the handle end. The coupling end couples to the coupling member of the stripping device. The separating portion allows the stripping member to be divided into first and second parts, and the first and second parts can be combined to each other to jointly receive the tendon. This avoids the generation of the incisions during the tendon transplantation. In addition, since the tendon stripper does not require any instrument for retaining the free end of the tendon, a convenient surgical procedure is provided.
