Abstract
An object of the present invention is to provide a safe surgical needle apparatus, and a surgical needle and a needle holder used therein, which can prevent the medical participants from being erroneously punctured with a tip end of the surgical needle and can permit a smooth tissue penetration of the surgical needle only when performing a suturing work. In accordance with the present invention, there are provided a surgical needle whose surface is formed from an electrically-insulating material except for its tip end portion and its tail portion to the latter of which a suture can be attached; a needle holder for clamping said tail portion of the surgical needle, in which at least a clamping surface thereof, which comes into contact with the surgical needle, is made of a conductive material and which includes a means for applying an electric current to the portion; and a surgical needle apparatus comprising the afore-mentioned surgical needle and needle holder, and an electric source for supplying an electric current to the surgical needle through the needle holder.
