A medical ligature gun uses a ligature to ligate the ill tissue. The ligature gun comprises a gun body (6). The gun body (6) comprises a gun handle (601), a gun head (602) and an elongated gun barrel (603) located therebetween. A raised strip (6033) is provided on the elongated gun barrel (603). A substantially T-shaped trigger structure (7) is provided in front of the gun handle (601). The trigger structure (7) is provided with a lateral transmission slide groove (7012) which is engaged with the raised strip (6033) provided on the elongated gun barrel (603) to allow the laterally reciprocating movement between the trigger structure (7) and the gun body (6). The ligature used with the medical ligature gun comprises a ligature head (1) and a ligature body (2) matched with the ligature head (1). The ligature head (1) is provided with a tongue part (101). The tongue part (101) is provided with multiple ratchets (1012), which are matched with the ligature body (2), and multiple protrusions (1013) for reversely unlocking the ligature. The ligature head (1) has a ligature hole (104) and multiple ridges (102) matched with the protrusions (1013). The tongue part (101) is extended from the main body of the ligature head (1). The protrusions (1013) are located on a top portion of the tongue part (101) and protruding from an upper surface of the ligature hole (104). |
