Abstract

A tube pushing and knotting device for medical suture wires is characterized in that a sliding tube (11) is slidably arranged in an outer tube (10) in a penetrating manner, the front end of the sliding tube (11) extends out of the outer tube (10) to form a sleeved part (111), a tying wire (20) is arranged in the sliding tube (11) in a penetrating manner and tied to form a loose knot (21) in the sleeved part (222), a tying ring (22) is formed between the extending part and the loose knot (21), a tying wire section (31) different from the tying wire (20) is arranged in a penetrating manner, when the tying wire (20) is pulled backwards, the sleeved part (111) is moved into the outer tube (10), the tying ring (22) is reduced and the tying wire section (31) is reversely folded to enable the reversely folded end (311) to sink into the front end of a threading hole (112), and the loose knot (21) falls off from the sleeved part (111) and forwards crosses the tying ring (22), tightly binding the knotted line segment (31) to form a line head structure (A) at the reverse folding position; the knotted wire section (31) of the wire can be easily and quickly formed into a rope head by a user through the structure (A), and the knotted wire section is suitable for operation of suturing wounds or forming heads by various wires.

Claims (9)

1. A push tube knotting device for medical suture wires is characterized in that an outer tube is provided, a sliding tube is slidably arranged in the outer tube, the front end of the sliding tube penetrates out of the outer tube to form a sleeving part, a threading hole is formed in the sliding tube in an axial direction in a penetrating way, a tying wire is arranged, the thread body is wound on the sheathing part to form a slip knot with more than one circle, the rear end of the thread body penetrates into the thread hole, a bundle of loop is formed at the part of the tying thread material between the slip knot and the front end of the thread hole, more than one section of tying thread section different from the tying thread material is penetrated in the bundle of loop, the rear end of the tying thread material is pulled backwards, the binding ring reversely folds more than one knotted line segment to form a reversely folded end which is sunk into the front end of the threading hole, wherein a piled polygon formed by the knotting wire and the tying wire which enter the sleeving part in pairs due to the reverse folding is accommodated in an inner circumference of the section of the sleeving part.
2. The push tube knotting device for medical suture wires of claim 1, wherein the stacked polygon is a pentagon.
3. The push tube knotting device for medical suture wires of claim 1, wherein the stacked polygon is a hexagon.
4. The push tube knotting device of claim 1, wherein more than two of the knotted string segments are threaded through the snare, and the more than two knotted string segments are portions of the same knotted string that are threaded through the snare twice or more.
5. The push tube knotting device for medical suture wires of claim 4, wherein a projected cross-sectional area of the stacked polygon has a compression set in the range of 3% to 30%.
6. The push tube knotting device for medical suture wires of claim 4, wherein a portion of the tying wire is fixed to the outer tube.
7. The push tube knotting device for medical suture wires of claim 5, wherein the packed polygon is a closest packed polygon.
8. The push tube knotting apparatus of claim 5, wherein the stacked polygon comprises at least one arcuate edge.
9. The push tube knot tying device for medical suture wires as claimed in claim 1, wherein more than two of said knotting line segments are threaded in the snare, the more than two knotting line segments being portions of the same knotting wire wound through the snare twice or more.
