DETAILED DESCRIPTION

[0031] The technical solution in the embodiments of the present invention will be clearly and fully described below in combination with the drawings in the embodiments of the present invention. Apparently, the described embodiments are merely part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those ordinary skilled in the art without contributing creative labor will belong to the protection scope of the present invention.

[0032] Embodiments of the present invention disclose a bidirectional guide suture device for pelvic floor reconstruction puncture, comprising:

[0033] a puncture catheter 1;

[0034] a bidirectional guide cable 2, wherein, one end of the bidirectional guide cable 2 is provided with a needle hole 21 for connecting stitches, and the other end is provided with a pulling hole 22 for pulling the bidirectional guide cable 2; the bidirectional guide cable 2 is arranged inside the puncture catheter 1, and the pulling hole 22 is located at the puncture end of the puncture catheter 1.

[0035] To further optimize the above technical solution, the puncture end of the puncture catheter 1 is provided with a beveled cutting edge 11.

[0036] To further optimize the above technical solution, the beveled cutting edge 11 is a single-sided cutting edge or a double-sided cutting edge.

[0037] To further optimize the above technical solution, the puncture end of the puncture catheter 1 is curved, and curved into a circular arc.

[0038] To further optimize the above technical solution, one end of the puncture catheter 1 away from the puncture end is connected with a handle 3; a through hole is formed inside the handle 3; and the puncture catheter 1 is sleeved inside the through hole.

[0039] To further optimize the above technical solution, the outer diameters of the bidirectional guide cable 2, the pulling hole 22 and a needle hole 21 are smaller than the inner diameter of the puncture catheter 1. The bidirectional guide cable 2 can be flexibly penetrated or withdrawn from both ends of the puncture catheter 1, does not cause the risk of secondary injury to other organ issues during guide, and can increase a surgical space. The resistance during penetration or withdrawal is small, and the puncture catheter 1 can adjust the angle and the posture arbitrarily, thereby having the advantages of convenient and simple operation and reduction of patient pain.

[0040] To further optimize the above technical solution, the bidirectional guide cable 2 can be bent and is molded by semi-flexible polymer plastic.

[0041] The operation process is as follows:

[0042] In use during the surgery, after the handle 3 is held to puncture the puncture catheter 1 into the relevant part of the human body, stitches are penetrated into the needle hole 21 of the bidirectional guide cable 2 and the bidirectional guide cable 2 is placed into the puncture catheter 1; the pulling hole 22 for pulling the bidirectional guide cable 2 pulls out the bidirectional guide cable from the puncture end of the puncture catheter 1, and the stitches also penetrate through the puncture catheter 1 along with the bidirectional guide cable 2 to reach a required part; after the stitches are removed, the bidirectional, guide cable 2 is bent in the surgical space, penetrates from the puncture end of the puncture catheter 1 into the puncture catheter 1, and is withdrawn from the body; and finally, the puncture catheter 1 is withdrawn from the body, and one puncture and leading operation can be completed by one puncture. The stitches penetrated into the human body are used to connect synthetic meshes to complete the surgery of female pelvic organ prolapse.

[0043] Each embodiment in the description is described in a progressive way. The difference of each embodiment from each other is the focus of explanation. The same and similar parts among all of the embodiments can be referred to each other.

[0044] The above description of the disclosed embodiments enables those skilled in the art to realize or use the present invention. Many modifications to these embodiments will be apparent to those skilled in the art. The general principle defined herein can be realized in other embodiments without departing from the spirit or scope of the present invention, Therefore, the present invention will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principle and novel features disclosed herein.
