Surgical needle, production method thereof, and needle holder

In a medical stapler, an anvil is disposed in the vicinity of an opening in a casing, and is disposed in a path of movement of a ram. A foremost staple placed on the anvil is shaped through the cooperation of the advancing ram with the anvil in such a manner that a pair of legs of this foremost staple are moved toward each other. The anvil has a shaping surface disposed in opposed relation to the ram. This shaping surface is inclined relative to the path of movement of the ram in such a manner as to approach the ram progressively toward the distal end of the shaping surface.

Medical stapler

A medical stapler includes a front wall having an opening at a lower end portion thereof. A mirror is mounted in the vicinity of an upper edge of this opening. A straight line, representing a wound pinched by a pincette by the operator, is reflected on the mirror. The operator adjusts the posture of the stapler so that the straight line of the actual wound can be aligned with the straight line reflected on the mirror, and in this condition the staple is shaped so as to effect the suturing of the wound.
