Problems solved by technology

This nail-making method is time-consuming and labor-intensive. Because the size of the nail is very small, it is difficult to make the slopes of the two nail feet into shape, and even if it is formed, it is difficult to meet the requirements of clinical use. Significant impact on the entire surgical procedure

Embodiment 1

[0027] As shown in Figure 1: Use stainless steel wire or titanium wire with the same diameter as the nail used in the stapler as the linear nail-making raw material 2, and wind it tightly and evenly on the mold with symmetrical slopes 1. More specifically, the shape of the mold 1 is consistent with that of the nail 4, which is a cuboid with two chamfered slopes. During the winding process, two parts of the linear nail-making raw material 2 are attached to the symmetrical slope of the mold 1 . As shown in FIG. 2 : by using a grinding wheel or a file as a cutting tool 3 , the linear nail-making raw material 2 is cut along the symmetrical slope of the mold 1 to form a nail 4 . During the entire truncation process, the interception modes of the two interception tools 3 are interception simultaneously or step by step interception. When implementing step-by-step interception, the two ends of the linear nail-making raw material 2 can be properly fixed with clamps to ensure that the ...

Embodiment 2

[0029] As shown in FIG. 4 : the mold 11 is in the shape of an hourglass hourglass with two big ends and a narrow middle, and two symmetrical triangular cut positions 6 are arranged in the middle of the mold 11 .

[0030] As shown in Figure 5: when making nails, the linear nail-making raw material 2 is tightly wound on the mold 11, and the nail-making raw material 2 is selected, that is, a stainless steel wire or a titanium wire with the same diameter as the nail. It is tightly and evenly wound on the timing hourglass-shaped mold 11, and then, through two cutting tools 3, namely, grinding wheels or files, the nail-making raw material 2 is cut off along the triangular cut 6 on the mold. As shown in FIG. 6 : while forming the nail foot slope 5 , two rows of closely arranged nails 4 , that is, nail groups of two units, are made. At the same time, during the interception process, the interception mode of the two interception tools 3 may be simultaneous interception or step-by-step ...

Embodiment 3

[0032] As shown in Figure 7: a stainless steel wire or titanium wire with the same diameter as the nail is selected as the nail-making raw material 2, and is evenly wound on the mold 12 with a sharp angle, and the sharp angle is an isosceles triangle. As shown in Figure 8: the top of the nail making raw material 2 is cut off with the cutting tool 3, so that the two slopes 5 of the nail foot are formed. As shown in Figure 9: At this point, the stainless steel wire or titanium wire becomes a row of closely arranged wires with bends 7 . Finally, the mold 12 with a sharp angle is removed from the bend 7, and the bend 7 of the nail making raw material 2 straightens to become a row of closely arranged nails 4. In this process, clamps can be used on both sides of the nail-making raw material 2 near the bottom of the sharp-angle mold 12 to ensure that no single nail 4 falls off during the entire demoulding process, and the effect of removing the bend 7 is better.

Abstract

The invention relates to the manufacturing of a nail, in medical equipment industry. It twists the linear material for making nails tightly to the symmetrical slant mold, intersecting the linear material to form the nail with each having two feet, each having a symmetrical slant surface. In this way, the binding machine used nails is realized mass production. With natural occurrence of two slant surfaces of the nail feet, symmetrical in location, consistent in shape, high in yield rate, it meets clinical requirement. It is simple, high in efficiency, low in cost, good in implementation effect, and with advances in this field.

Description

technical field [0001] The invention relates to a method for manufacturing a staple, in particular to a method for manufacturing a staple for a stapler used in surgery, and belongs to the technical field of medical instruments. Background technique [0002] Nails are necessary supplies for using a stapler to implement surgical operations. The manufacturing method of this class of nails in the prior art is: first select a stainless steel wire or titanium wire with the same diameter as the stapler for the stapler, and then use needle-nose pliers to It is bent and folded into the desired shape of the nail, then cut with scissors, and finally filed with a file or cut with scissors to form two slopes of the nail foot. This nail-making method is time-consuming and labor-intensive. Because the size of the nail is very small, it is difficult to make the slopes of the two nail feet into shape, and even if it is formed, it is difficult to meet the requirements of clinical use. It has...
