Technical Field

The invention belongs to the technical field of blood vessel ligation, and particularly relates to a blood vessel ligation wire feeder in an operation.

Background

In the operation process, a doctor generally uses a vascular forceps to deliver a ligature in a surrounding manner, so that the ligature firstly bypasses a blood vessel to be ligatured, and then is led out to be further knotted after bypassing a target blood vessel, and finally the target blood vessel is tied.

The following problems exist in the above operation: due to the complexity of the nerve and blood vessels at the operation position, especially for the small incision and the ligation of blood vessels in deep tissues, the circular wire feeding of the vascular clamp is difficult to operate in a narrow space, and is more difficult for the deep tissues. Aiming at the difficulty of target blood vessel ligation, medical instruments used in the operation sometimes cannot send a ligature to a target blood vessel and can not bypass the target blood vessel, so that the whole operation time is prolonged, and even unnecessary blood loss occurs because the blood vessel cannot be ligated in time.
