The invention provides a medical clamp which comprises a clamping device, wherein the clamping device comprises a clamping arm, a small steel sleeve, a transmission shaft and a location sleeve; the clamping arm is clamped to the transmission shaft, the clamping arm and the transmission shaft are arranged in the location sleeve, one end, close to the clamping arm, of the location sleeve is tightlyhooped by the small steel sleeve, a through hole is arranged at one end, close to the clamping arm, of the transmission shaft, and an elastic coil penetrates through the hole to achieve a traction effect in operation. The medical clamp disclosed by the invention can be applied to operation under endoscopes, the whole structure and a use method of a medical clamp traction system are further improved, the traction direction is more flexible, the situation of repeatedly entering and exiting the endoscopes is avoided, the medical clamp is safer and more convenient to use, and the damage risk to the tongue root, pars laryngea pharyngis and gastrointestinal mucous membranes of other positions is avoided.
