Abstract

The invention relates to the technical field of medical apparatuses, and provides self-unlocking obstetric forceps for department of gynaecology and obstetrics. The self-unlocking obstetric forceps comprise a clamping transmission assembly and a traction protection assembly, wherein the clamping transmission assembly is formed by the connection of a connecting rod structure and a power shaft; thetraction protection assembly consists of an outer ratchet wheel, an inner ratchet wheel and a spring ratchet; the clamping transmission assembly is connected with a clamping assembly to complete the work of far end control; and the traction protection assembly is connected with a grasping and holding assembly to form a traction force upper limit protection. According to the self-unlocking obstetric forceps disclosed by the invention, a simple and stable structure is adopted, so that on one side, far end control of the clamping motion is realized, and on the other side, an unhooking protectionmechanism of which the upper limit of the traction force can be preset is formed through the traction protection assembly, and after the unhooking mechanism is triggered, the clamping assembly is recovered to an initial opening angle.
