Description
Technical Field
The invention belongs to the technical field of abdominal cavity minimally invasive surgery instruments, and particularly relates to a ligation traction apparatus for an abdominal cavity minimally invasive surgery.
Background
The abdominal cavity minimally invasive surgery is popular among patients due to small wound and fast recovery. In the process of abdominal cavity minimally invasive surgery, traction (traction and distraction) is often needed to be carried out on human tissues so as to obtain a better surgical field. If the tissue to be pulled is small, such as a ureter, a blood vessel, a fallopian tube, the pulling can be performed with the jaws, but if the tissue to be pulled is large, such as a small intestine, a large intestine, a rectum, etc., the size thereof is far larger than the opening width of the jaws, and thus the pulling can be performed only after tying and knotting with flexible wires. However, the above-mentioned traction method by tying knots has the following disadvantages: firstly, because the minimally invasive surgery is operated under an endoscope, the knotting and threading operations are difficult, precious time is wasted, and the untwisting process also needs to take time; secondly, after the knot is tied, the size (namely the tightness degree of the knot) of the closed lantern ring is fixed and cannot be adjusted; if the knot is too loose, the tissue is easy to slip and is not beneficial to positioning, and if the knot is too tight, the knot is difficult to untie; thirdly, a section of flexible wire is still connected between the knotted part and the metal operating rod, so that the position control of the tissue to be dragged is not direct, not quick and even inaccurate, namely the position control degree of the tissue to be dragged is not ideal, and the position of the tissue to be dragged cannot be freely and quickly changed as desired (for example, when the tissue is expected to move 2 cm to the left, if the metal operating rod is simply moved 2 cm to the left, the tissue can only move 1.5 cm to the left, and simultaneously move 1 cm to the front).
