A cannula (100) for catgut-embedding therapy according to the present invention comprises: a tube (110) having a closed front end; and a hole (120) penetrating a side of the tube (110), wherein the cannula (100) comprises a ball (140) inserted into the tube (110) and arranged to guide a catgut-embedding string (130) to the hole (120). The present invention can advantageously solve the problem of spikes (131) getting stuck at the front end (121) of the hole (120) and failing to come out. |
