Abstract: To provide a transplant-use tendon harvesting device that can harvest a tendon more easily. The transplant-use tendon harvesting device 1 includes a mantle portion 5 and a tendon separation element 8. The mantle portion 5 is configured to be inserted into a body from an incision portion 4 and moved along a tendon 3 to be harvested. The tendon separation element 8 is formed of an elastic member and attached to the mantle portion 5 to move along the tendon 3 together with the mantle portion 5 so as to separate an end portion of the tendon 3 on the moving direction side from another tissue. The tendon separation element 8 includes a separation functional portion 6 to cause the tendon 3 to pass inside at a time of moving along the tendon 3 to separate the tendon 3 and linear portions 11 and 12 inserted into the mantle portion 5 to be fixed.

Abstract: To provide a surgical instrument for performing incision that enables surgery to be performed safely and easily, with minimal invasiveness and a reduced risk of damaging a tissue, such as a tendon, nerve, or blood vessel. This surgical instrument enables a tendon sheath and an aponeurotic membrane to be incised safely without significantly incising the skin or subcutaneous tissue, and makes it possible to conduct surgery percutaneously at an extremely low level of invasion.
