Description

Fig.2 is a cross-sectional view in direction of the arrows on line 2-2 of FIG. 1;

Fig. 3 is a cross-sectional view of the needle showing shows the engagement of the jaws of the needle holder

In Fig. 1, the needle, generally designated by the reference numeral 10, consists of a curved needle body 11 which is essentially in the shape of an equilateral triangle in cross section, with the surface IS of the triangle parallel to the needle axis of curvature and the edge 13 projecting outwards with respect to the needle arch. Such a needle is called an inverted cutting edge needle. The needle has a tip 16 and a first triangular section 22 which gradually tapers backwards from the tip with a cutting edge on each apex of the triangle. A second triangular section 18 has edges which are slightly rounded or flattened so that they are not sharp enough to cut the tissue. The shape of the needle changes towards the rear so that the triangular section gently merges into a round section 14.

leads, and the thread 12 is at the round -chnitt attached The longitudinal ribs 20 are located on the surface 19 of the second section of the needle The first section of the needle is expediently essentially shorter than the second section. When sewing, the second section is gripped by the needle holder and the longitudinal ribs and the edge of the needle opposite the ribbed needle surface are in engagement with dun toothed inner surfaces of the jaws of the needle holder, so that angular and rotational movements of the needle in the needle holder are essentially eliminated.

2 shows in cross section the position of the longitudinal ribs on the surface 19 of the needle body 11 and

their relationship to the edge 13 of the needle body.

The partial cross-sectional view of Figure 3 shows the needle as it -is taken of the needle holder by the jaws 72 and 74, -and shows particularly the manner in which the serrated internal surfaces ¹ *

Round needles and some When sewing during surgical operations as cutting needles are rrit two flattened surfaces, the surgical needle is provided by a needle holder, both of which lie parallel to the Nidel axis of the curve between the tip of the needle and its rear, and are used on the part of the needle for attaching the fax End near the end used to attach the thread and at an angle of nearly 90 ° with respect to the thread, and when this needle holds the jaws of the needle holder ^: ..
