| description | The invention relates to a blood vessel in-situ puncture sheathing canal which comprises a hollow tube body, and side holes penetrating through the inner surface and the outer surface of a wall body in the same radial direction are formed in the corresponding positions of two opposite side wall bodies of the tube wall, close to the front end of the hollow tube body, of the hollow tube body respectively. The front end of each side hole is also provided with a side seam which is communicated with the side hole and extends towards the front end part, and the two side seams gradually incline towards the same side of the tube wall of the hollow tube body until the two side seams converge and are communicated in the process of extending towards the front end part from the corresponding position of the top of the front end of the side hole to form a guide wire separation seam which is convenient for the guide wire to separate out of the hollow tube body; the opening width of the side seam and the guide wire separati |
