Description

Technical Field

[0001] The invention belongs to the technical field of microsurgery and free flap surgery, and in particular relates to a knotter for ligating perforator blood vessels. Background Art

[0002] Ligation refers to the use of certain means (such as catgut) to tie up certain tubes (such as blood vessels, vas deferens, fallopian tubes, etc.) of the human body or organism or to achieve the same effect. "Ligation" is usually considered a minor operation;

[0003] According to a disclosed knotter based on bionic principle (publication number: CN219928124U), it includes a support platform, a bag-supporting mechanism, a rope-threading mechanism arranged opposite to the bag-supporting mechanism for threading a rope through the bag, a shearing mechanism located outside the rope-threading mechanism for cutting the rope in the rope-threading mechanism, a rope-pulling mechanism used in conjunction with the rope-threading mechanism for adjusting the position of the rope head and tightening it, and a rope-winding mechanism cooperating with the rope-pulling mechanism to complete the knotting action. The rope-threading mechanism and the shearing mechanism are located on the support platform, the bag-supporting mechanism and the rope-pulling mechanism are located outside the support platform, and the rope-winding and knotting end of the rope-winding mechanism is opposite to the shearing end of the shearing mechanism. The automatic knotter can save manpower, improve the knotting efficiency of a fixed single knot, and greatly liberate labor. However, in the above-mentioned device, it is difficult to adjust the distance between the card blocks through the cooperation of components such as the support platform and the bag-supporting mechanism, resulting in the inability to accurately adjust according to the thickness of the patient's blood vessels, which needs to be improved.
