Detailed Description
As shown in the attached drawings, the utility model comprises a cylindrical needle bar 1, one end of the cylindrical needle bar 1 is provided with a flat needle point 2, the front end of the flat needle point 2 is a triangular puncture part 3, and two sides of the triangular puncture part 3 are both provided with cutting edges 4; a threading hole 5 is formed on the flat needlepoint 2 close to the triangular piercing part 3, a trumpet-shaped incoming line notch 7 is formed in the flat needlepoint 2 from a first side edge 6 to the threading hole 5, and a trumpet-shaped outgoing line notch 8 communicated with the trumpet-shaped incoming line notch 7 is formed in the flat needlepoint 2 from the threading hole 5 to the first side edge 6.
The flat needle point 2 and the cylindrical needle bar 1 are an integral piece, and the flat needle point 2 is formed by forging and grinding the end part of the cylindrical needle bar 1.
The cutting edges 4 on both sides of the triangular puncture part 3 are arc-shaped cutting edges.
The diameter of the cylindrical needle rod 1 is 2mm, and the length is 180 mm and 220 mm.
The diameter of threading hole 5 is not less than 1mm, the width of the larger opening end of horn-shaped incoming line notch 7 is greater than the diameter of threading hole 5, the width of the smaller opening end of horn-shaped incoming line notch 7 is 0.2-0.3mm, the width of the smaller opening end of horn-shaped outgoing line notch 8 is equal to the width of the smaller opening end of horn-shaped incoming line notch 7, and the width of the larger opening end of horn-shaped outgoing line notch 8 is smaller than the radius of threading hole 5.
The working mode and principle are as follows: after the laparoscopic surgery is finished, when the puncture hole is closed, the common suture absorbable line 2-0 is folded in half in vitro and enters the threading hole 5 after sequentially passing through the trumpet-shaped incoming line incision 7 and the trumpet-shaped outgoing line incision 8, the folded double-stranded suture is punctured from the subcutaneous tissue at one side of the laparoscopic incision needing to be sutured, and the laparoscopic reaches a proper position under direct vision. Withdrawing the suture from the threading hole 5 through the abdominal operation forceps, and then withdrawing the suture needle to finish the thread-feeding process; a hollow needle without a thread is inserted into the subcutaneous tissue on the opposite side of the incision of the laparoscope needing to be sutured, the laparoscope reaches a proper position under direct vision, the thread which is already arranged at the subcutaneous tissue enters the thread hole 5 after passing through the trumpet-shaped thread inlet incision 7 and the trumpet-shaped thread outlet incision 8, the suture needle with the thread is withdrawn, and then the thread is withdrawn from the thread hole 5 in vitro, so that the thread outlet process is completed; the two ends of the suture are tied off under the incision skin in a conventional surgical mode, and a suturing process is completed.
The cutting edges 4 on two sides of the triangular puncture part 3 are arc-shaped cutting edges, so that the flat needle point 2 can be conveniently and rapidly punctured, and the punctured wound area can be reduced by the flat needle point 2.
