Embodiment Construction
[0053] The present invention will be further explained below in conjunction with specific examples.
[0054] figure 1 Shown is the structure of the sheath core used for delivery of interventional instruments in the present invention, including a core tube 101 , a guide head 102 and an implantation instrument fixing head 103 .
[0055] The guide head 102 is fixedly connected with the distal end of the core tube 101. The guide head 102 has a head 104 and a tail 105. The head 104 and the tail 105 of the guide head 102 are conical structures, and the head 104 has a streamlined shape. The shape can avoid scratching the inner wall of the blood vessel, and is also conducive to guiding the entire delivery system to advance along the blood vessel. The head 104 of the guide head 102 is also provided with a radial protruding ring 106 for blocking the end face of the sheath, figure 2 It shows the status diagram of the guide head when the sheath core and the sheath tube are used togeth...
