This invention provides a tether adjuster and its method of use. The tether adjuster includes a housing, a clamping mechanism, and a tension adjusting mechanism. The clamping mechanism is connected to the distal end of the housing and is capable of clamping an apical pad. The apical pad is used to connect to the proximal end of the tether, and the distal end of the tether is connected to a heart valve prosthesis. The clamping mechanism includes a first driving part and a jaw. The jaw includes two clamping arms symmetrically arranged circumferentially on the housing. The first driving part is connected to the two clamping arms respectively and is used to drive the distal ends of the two clamping arms to move in a direction of mutual approach to open the jaw, or to drive the distal ends of the two clamping arms to move in a direction of mutual approach to close the jaw. The tension adjusting mechanism is connected to the housing and to the proximal end of the tether, and is used to drive the proximal end of the tether to move relative to the heart valve prosthesis to adjust the tension of the tether. When adjusting the tension of the tether using the tether adjuster, two symmetrically arranged clamping arms are used to clamp the apical pad, so that the apical pad is subjected to symmetrical and balanced clamping force, maintaining the stability of the apical pad. This allows the operator to manipulate the tension adjustment mechanism to move the proximal end of the tether and thus adjust the tension of the tether.
