Hemostatic clip

A hemostatic clip, comprising:

• a traction mechanism, a distal end of the traction mechanism defining an inner bore;
• and
• a clamping mechanism comprising a constricting sleeve and a clip head assembly, the constricting sleeve provided thereon with a first locking member, the clip head assembly partially disposed within the constricting sleeve, the clip head assembly comprising an engagement member and a clip head body, the engagement member having a proximal end inserted in the inner bore and forming an interference fit with the inner bore, a proximal end of the clip head body connected to a distal end of the engagement member, a distal end of the clip head body protruding out of a distal end of the constricting sleeve, the clip head assembly provided with a second locking member, wherein:
• the hemostatic clip is configured so that, when the second locking member is separate from the first locking member, the traction mechanism is allowed to drive, under the action of an external force, the clip head assembly to move forth and back along an axis of the constricting sleeve, thereby switching the clip head body between an opened configuration and a closed configuration;
• and
• the hemostatic clip is also configured so that in the closed configuration of the clip head body, movement of the clip head assembly along the axis of the constricting sleeve is prevented when the second locking member is connected to the first locking member, and the proximal end of the engagement member will disengage from the inner bore when a pulling force greater than a first predetermined value is applied to the traction mechanism.
