Embodiment Construction
[0016] figure 1 It is a schematic sectional view of the structure of the invention, from which it can be seen that the present invention is composed of a section of straight solid steel wire 1; it is characterized in that a long side groove 1B is provided on the side of the solid steel wire 1, and the solid steel wire The section of 1 is circular with notches; one end of the solid steel wire 1 is in the shape of a triangular needlepoint 1A, and the tip of the needlepoint 1A is located on the axis of the solid steel wire 1 .
[0017] figure 2 It is a schematic cross-sectional view of the solid steel wire of the present invention. It can be seen from this that when the solid steel wire 1 passes through the front end of the sleeve on the trocar, a formation can be formed between the side groove 1B on the solid steel wire 1 and the sleeve. A channel formed by the sleeve tube and side groove 1B, and this channel can meet the needs of blood backflow observation during puncture; wh...
