Surgery standardization is knotd and is trained and assess device

The utility model provides a surgery standardization is knotd and is trained and assess device, includes the bottom plate, is equipped with orthogonal arrangement's first infrared switch and infrared switch of second and flexible column on the bottom plate, is connected with the ring of the training that is used for tiing a knot on the top of flexible column, first infrared switch includes an infrared emitter and an infrared receiver just the flexible column lies in between an infrared emitter and the infrared receiver, the infrared switch of second includes that the 2nd infrared emitter and the 2nd infrared receiver and flexible column lie in between the 2nd infrared emitter and the 2nd infrared receiver, when being connected with indicating circuit and initial condition respectively between the transmitting terminal of first infrared switch and the infrared switch of second and the receiving terminal, the flexible column shelters from infrared ray and the infrared ray from two infrared emitter to two infrared receiver transmission of an infrared emitter to infrared receiver transmission simultaneously. The utility model discloses whether can differentiate that the surgery is knotd accords with normal requirement.
