すようにかしめ止めする。After being corrected by the heater 7, the surgical thread S is fed out in the direction of the caulking mechanism 1. At this time, as shown in FIG. 2, the suture needle N together with the work W has the rear end Na as the first guide portion. It is positioned so as to match the tip portion 3a of No. 3. Therefore, when the surgical thread S is fed by the feed roller 8, the surgical thread S passes through the first guide portion 3 and enters the hole portion Nb of the suture needle N. In this state, the dies 1a to 1d are moved in the vertical and horizontal directions to caulk the rear end Na of the suture needle N as shown in FIG.

及び縫合針Ｎの孔部Nbへの挿し込みが容易になる。The suture needle N, to which the surgical thread S has been crimped in this manner, is sent by the transport mechanism 2 in the direction for pulling out the surgical thread S as it is, and after moving a predetermined distance, the surgical thread S is moved.
Is cut by the cutting mechanism 10. At this time, the surgical thread S
Before or after the cutting, the surgical thread S is pressed and the work W
The surgical thread S by moving the suture needle N with a constant force.
It is inspected whether to get out of. The surgical thread S may be cut obliquely with respect to the longitudinal direction of the surgical thread S by feeding the next surgical thread S to the first guide portion 3,
Also, the suture needle N can be easily inserted into the hole portion Nb.
