Abstract: An injectable material injection device includes a cannula that slides inside a hypodermic needle. The hypodermic needle includes a beveled tip. The cannula includes a base that is configured to establish a sealed connection.

Abstract: The invention essentially relates to a surgical needle (17) comprising a long hollow body (18) and two ends (19, 20). The body (18) comprises a ventral wall (21) and a dorsal wall (22) which are connected to one another. According to the invention, the dorsal wall (22) and the ventral wall (21) extend along the long axis of the needle (17). Each of the two ends (19, 20) comprises a hollow beveled tip (23, 24). The needle (17) also comprises a hole (25) which is provided in the dorsal wall (22) of the body (18) and a slit (26) which is provided in the ventral wall (21). In this way, a suture (30) can slide inside the hollow body (18) of the needle, the suture being retained in position by the knot (29) or means for stopping thereof. For said purpose, the smallest diameter (27) of the hole (25) is greater than the largest width (28) of the slit (26).
