Suturing device for percutaneous vein ligation

Abstract

The invention provides a transfixion device for percutaneous vein ligation. The transfixion device comprises a transfixion part, a guide part and an operation part, the suturing piece comprises a guide part and a suture, an elastic blocking piece is arranged at the end of the suture, the guide part is provided with a first guide cavity for the suture to penetrate through, and the width of the elastic blocking piece in a compressed state is larger than the diameter of the first guide cavity; the guide piece is provided with a second guide cavity allowing the sewing piece to penetrate through, and a first connecting part is arranged at the end of the guide piece; the operating part comprises a second connecting part, the second connecting part is rotationally connected with the first connecting part, a channel allowing the elastic blocking part to penetrate through is formed in the end, away from the second connecting part, of the operating part, the second connecting part is provided with a third guide cavity allowing the sewing part to penetrate through, and the channel and the third guide cavity are oppositely arranged. The device solves the problems that an existing suturing device is contrary to a conventional suturing habit, operation is inconvenient when the front end of the existing suturing device pierces into tissue, and then the suturing hand feeling of a doctor is reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a suturing device for percutaneous venous vessel ligation. Background technique [0002] High ligation of great saphenous vein or superficial vein ligation is one of the important means of surgical treatment of great saphenous vein varicose. The traditional ligation method requires an incision in the skin, and then the vein is picked out and ligated. This method is more invasive and slow postoperative recovery. A minimally invasive superficial vein ligation method emerged at the historic moment. The Chinese patent with the notification number CN209899494U discloses a suturing device for percutaneous great saphenous vein ligation. The Chinese patent with the notification number CN209136728U discloses a venous vessel Minimally invasive ligation stapler, the Chinese patent with the notification number CN211131231U discloses a tubular tissue suturer, and 3 kinds of suturing...

AI Technical Summary

Problems solved by technology

The suturing device adopts the rotating connection mode of the operating part and the guide part, which can be more convenient to operate, and solves the problem that the suturing device is contrary to the conventional suturing habit, and it is inconvenient to operate when the front end penetrates into the tissue, thereby reducing the doctor's suture feel. problems, and the device can complete the suture embedding with one suture, and the suture forming a loop in the human body will not wrap around too much perivascular tissue, the knot is firm, the suture effect is good, and it also reduces the operation time. trauma area, strong practicability
