Definitions
- the present invention relates to the field of medical surgical stapling instruments, and more particularly to a staple.
- the working principle of the stapler is basically the same as that of the stapler.
- the staple is installed in the nail, the tissue to be stitched is placed between the staple and the anvil, and the distance between the staple and the anvil is adjusted. And then firing, causing the staples to penetrate into the tissue and form in the anvil to suture the tissue.
- the use of the stapler greatly reduces the operating time of the surgery, improves the efficiency of the operation, and ensures a high success rate of the surgery.
- a staple comprising a first nail body and a second nail body, wherein the first nail body and the second nail body are intertwined to form a spiral portion; the first nail body and the second nail body are located at One end of the same side of the spiral portion respectively extends in a direction perpendicular to the spiral portion to form a first crown portion and a second crown portion; and the first nail body and the second nail body are located in the spiral The other ends of the same side of the portion are respectively extended in a direction parallel to the spiral portion to form a first nail leg portion and a second nail leg portion.
- the first nail leg portion and the second nail leg portion penetrate the tissue to be sutured under the action of an external force; then the first nail leg portion is bent toward the side where the second crown portion is located, The two nail legs are bent toward the side where the first crown portion is located, and the first nail portion and the second nail portion again penetrate the tissue to be stitched, and the staples exhibit a B-like structure to complete a stitching. Since the intermediate portion of the B-shaped shape presented by the staple is composed of a spiral formed by the first nail body and the second nail body being intertwined, the above-mentioned staple has higher strength and toughness than the conventional staple. It is not easy to deform.
- FIG. 1 is a schematic structural view of a staple of an embodiment
- Figure 2 is a view showing the working state of the staple of Figure 1;
- FIG. 3 is a schematic structural view of a staple of another embodiment.
- Fig. 4 is a view showing the working state of the staple of Fig. 3.
- a staple 10 of an embodiment includes a first nail body 100 and a second nail body 200.
- the first nail body 100 and the second nail body 200 are entangled with each other to form a spiral portion 300.
- first nail body 100 and the second nail body 200 are the same.
- first nail body 100 and the second nail body 200 are both circular in cross section, and the first nail body 100 and the second nail body 200 are made of titanium metal.
- the first nail body 100 and the second nail body 200 are respectively located at one end of the same side (ie, the same end) of the spiral portion 300, and respectively extend in a direction perpendicular to the spiral portion 300 to form the first crown portion 110 and the second crown portion 210. That is, the first crown portion 110 and the second crown portion 210 are disposed in parallel, and the spiral portion 300 is perpendicular to the plane in which the first crown portion 110 and the second crown portion 210 are located.
- first nail body 100 and the second nail body 200 on the same side (ie, the same end) of the spiral portion 300 are respectively extended in a direction parallel to the spiral portion 300 to form the first nail leg portion 120 and the second nail leg portion 220.
- first end surface 122 and the second end surface 222 of the ends of the first nail leg portion 120 and the second nail leg portion 220 are chamfered surfaces.
- the first staple leg portion 120 and the second staple leg portion 220, which have beveled faces, are more likely to penetrate the tissue to be sutured.
- first staple leg portion 120 and the second staple leg portion 220 have the same length.
- the first nail leg portion 120 is bent toward the side where the second crown portion 210 is located, and the second nail leg portion 220 faces the side where the first crown portion 110 is located. Bending, forming a standard B-like structure (see Figure 2), which in turn makes the tissue to be suture more uniform.
- the lengths of the first nail leg portion 120 and the second nail leg portion 220 may also be different, and the staple 10 forms a non-standard B-shaped structure during operation to satisfy some special stitching. happening.
- the distance between the first nail leg portion 120 and the second nail leg portion 220 is 1 to 2 times the diameter of the first nail body 100.
- the spacing distance is too small and may cause the first staple leg portion 120 and the second staple leg portion 220 to penetrate tissue at the same location.
- the spacing distance is too large, resulting in a smaller cavity in the formed B-shaped structure, which is not conducive to suturing thicker tissues.
- the first nail leg portion 120 and the second nail leg portion 220 penetrate the tissue to be sutured under the action of an external force; then, the first nail leg portion 120 faces the second crown under the action of an external force.
- One side of the portion 210 is bent, and the second nail leg portion 220 is bent by the external force toward the side where the first crown portion 110 is located, and the first nail leg portion 120 and the second nail leg portion 220 penetrate again.
- the sutured tissue is sutured once so that the staple 10 assumes a B-like structure. Since the suture 10 described above penetrates the tissue to be suture twice during the suturing of the tissue, the suture 10 can suture the tissue to be sutured more closely.
- the middle portion of the B-shaped structure presented by the staple 10 is constituted by the spiral portion 300 formed by the first nail body 100 and the second nail body 200 intertwined
- the above staple 10 is opposed to the conventional staple (traditional
- the middle portion of the B-shaped structure formed by the bending of the two free ends of the staple leg of the staple is similar to the structure of the ordinary stapled molding, and the two free ends are easily deformed) with higher strength and toughness.
- the suture 10 described above can maintain the original suture state for a long time when used for suturing a thick and large tissue, and the staple 10 is not easily deformed.
- the suture 10 of the above structure has the characteristics of excellent molding, convenient suturing and high suturing efficiency.
- the end of the first crown portion 110 is bent to form a hollow first annular structure 130
- the end of the second crown portion 210 is bent to extend to form a hollow second annular structure 230.
- the first annular structure 130, the second annular structure 230, the first crown portion 110 and the second crown portion 210 are on the same plane.
- the first nail leg portion 120 and the second nail leg portion 220 penetrate the tissue to be sutured under the action of an external force; then the first nail leg portion 120 is externally
- the second nail portion 220 is bent toward the second annular structure 230, and the second nail leg portion 220 is bent toward the first annular structure 130 by the external force, and the first nail leg portion 120 and the second nail leg portion 220 are again Penetrate the tissue to be sutured.
- the end of the first nail leg portion 120 is bent and buckled under the action of an external force.
- the suture 10 can tightly suture the tissue, and is not likely to cause a bleeding infection or the like; at the same time, the suture 10 can maintain the original suture state more stably, and is more practical.
- the first annular structure 130 and the second annular structure 230 are symmetrical with respect to the center of the spiral portion 300. That is, after the second annular structure 230 is rotated 180 degrees around the spiral portion 300, it can substantially coincide with the first annular structure 130.
- the staple 20 includes a first staple body 400 and a second staple body 500.
- the first nail body 400 and the second nail body 500 are entangled with each other to form a spiral portion 600.
