Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to an improved traction device for tissue clamps. Background Art

[0002] Tissue clamp is a common medical device for closing wounds during endoscopic treatment of ESD. During use, in order to better expose the wound, the clamp head is used to clamp the tissue near the wound, and then the position of the clamp head is pulled by a traction device to expose the wound.

However, they do not take into account that sometimes the patient's condition is more urgent. At this time, the traction rope is tied to the head of the tissue clamp, which is time-consuming. In addition, in order to ensure a clear field of vision, the excess rope tied to the clamp head needs to be shortened, and the overall efficiency is low. Utility Model Content
