Abstract: The protective instrument for suturing is formed by a rigid longitudinally concavo-convex body member having rounded edges and blunt ends. It is provided with a handle, so that in use the concave portion is facing the inner surface of the incision and the convex portion faces the viscera, organs, vessels, nerves or other parts of the patient under operation. The purpose of the instrument is to guide the suture needle in replacement of the gloved finger of the surgeon, whereby pricks in the surgeon's finger or in the patient's viscera or other organs are avoided, preventing the infections or lesions which such pricks may cause.
