Detailed Description

The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.

Example 1

A suture puncture component is provided with a puncture cannula and a puncture cone, wherein the puncture cone extends into the puncture cannula; the puncture cannula is provided with an outer tube 1 and a cannula base 5 positioned at the top end of the outer tube, the puncture cone is provided with a puncture rod 6, the bottom end of the puncture rod 6 is provided with a puncture head 8, and the top end of the puncture rod 6 is provided with a puncture cone base 7; the suture puncture component is provided with a suture channel;

the suture passage comprises a groove 9 and an inclined hole 3, the groove 9 is positioned on the outer wall of the puncture rod 6 and is provided with a groove 9, and the inclined hole 3 which is obliquely arranged downwards is arranged on the outer tube; the inner wall of the lower part of the outer tube is provided with a limit boss 4, the inclined hole 3 is positioned right above the limit boss 4, the inclined hole 3 is arranged near the limit boss 4, and the limit boss 4 is clamped into the groove 9 when the puncture cone extends into the puncture casing.

The included angle alpha between the central axis of the inclined hole 3 and the central axis of the outer tube 1 is 20 degrees. The casing base 5 is provided with a mark for marking the inclined hole 3, and when the puncture cone extends into the puncture casing, the groove 9 is only required to be aligned with the inclined hole mark, so that the groove 9 can be positioned.
