On the other hand, the insertion arm 52 is stopped by the upper boss 42 of the main arm 4 when moving rightward, so that the slot plate 5 is fixed to the main arm 4. It can also be seen that since the second straight end surface 442 and the third straight end surface 522 abutting each other are not externally contacted, the abutting state cannot be released without being broken, and thus the medical device is disposable and the safety of health is improved.

As shown in fig. 14, both ends of the beam 45 protrude in the left-right direction, and can abut against the end surface of the hoop 11 near the second end of the rod 4 to form a stopper. This limit structure cooperates with the end wall 46 limit structure at the other end of the rod 4 so that both ends of the rod 4 are limited, so that the rod 4 cannot be separated from the main body 1. This also helps to achieve disposability of the medical device.
