When the tension of the tendon tissue of the human body needs to be measured, a suture for suturing the tendon tissue is led out, and then the end part of the suture passes through a thread passing hole on the inner core and is hung on a suture hook of the outer core; afterwards, human tendon tissue drives the suture shrink, then the suture passes through suture hook pulling outer core, interior dog and pointer and removes, and elastic deformation takes place simultaneously to the spring, and after reaching balanced state, the scale that the pointer instructed is the tension of human tendon tissue this moment promptly. When the measurement is finished, the suture is released from the suture hook, and the outer core and the pointer on the outer core are reset under the action of the spring. Through the use of the tendon tissue tension measuring device, the tension condition of human tendon tissue can be very conveniently measured in the operation process, thereby improving the operation accuracy and the operation effect of the operation.
