Detailed Description

In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.

Fig. 1 shows the spatial structure sketch map of the ligation clip according to a specific embodiment of the utility model, as shown in the figure, the utility model discloses a ligation clip is whole as integrated into one piece's V-arrangement structure, including a V-arrangement clamp body 1, V-arrangement clamp body 1 is formed by connecting two

arc arm lock

11, 12, particularly, the utility model discloses a ligation clip includes the V-arrangement clamp body 1 that comprises a first arc arm lock 11 and a second arc arm lock 12 an organic whole, and the free end of first arc arm lock 11 and second arc arm lock 12 is pothook 13 and dop 14 respectively. In operation, for stopping bleeding, the ligation clip can be clamped between the V-shaped clamp body 1, and the blood vessel can be firmly clamped between the two arc-shaped

clamp arms

11 and 12 by snapping the hook 13 onto the clip head 14 to close the ligation clip, which can be seen in fig. 2, which is a schematic view of the ligation clip shown in fig. 1 after closing.

The opposite inner sides of the first arc-shaped clamping arm 11 and the second arc-shaped clamping arm 12 are provided with two rows of staggered anti-slip teeth 15, and the anti-slip teeth 15 are used for firmly occluding blood vessels when the ligation is clamped between the two arc-shaped clamping

arms

11 and 12, so as to prevent the blood vessels from slipping.

The first arc-shaped clamping arm 11 has a cylindrical clamping hook clamping body 17 at the end close to the clamping hook 13, the second arc-shaped clamping arm 12 has two opposite clamping head clamping bodies 16 at the end close to the clamping head 14, a guide groove 18 facing the clamping hook is arranged between the two clamping head clamping bodies 16, and a guide inclined surface 19 is arranged on the outer side of the clamping hook 13.

The hook clamping body 17 and the chuck clamping body 16 are arranged to clamp the hook clamping body 17 and the chuck clamping body 16 by using a tool such as a clip applier and the like in the process of closing the ligation clip, then external force is applied to the inner side from the outer sides of the two arc-shaped clamping

arms

11 and 12, so that the hook 13 and the chuck 14 are close to each other, the guide inclined plane 19 on the outer side of the hook 13 slides along the guide groove 18 on the inner side of the chuck, and finally the hook 13 is clamped on the chuck 14.

In order to facilitate the operation of the tool such as a clip applier, in a preferred embodiment, the hook clamping body 17 and the chuck clamping body 16 preferably have similar shape structures, as is clear from fig. 3, the hook clamping body 17 is a cylinder symmetrically arranged at the outermost side of the hook 13, the chuck clamping body 16 is also symmetrically arranged at the outermost side of the chuck 14, and one side of the chuck clamping body 16 departing from the hook clamping body 17 is also a cylindrical surface, the diameter of the cylindrical surface is equal to the diameter of the cylinder of the hook clamping body 17, so that the tool such as a clip applier can be designed with the same clamping structure, and when external force is applied from the outer side to the inner side of the two arc-shaped clamping

arms

11, 12, the cylindrical surface of the hook clamping body 17 and the cylindrical surface of the chuck clamping body 16 with the same diameter can be clamped conveniently.

In order to provide a better closing force and to make the closure of the clip more reliable, the side of the clip 14 facing away from the hook 13 has a clip flat 141, and the inner side of the hook 13 has a hook flat 131 that can engage with the clip flat 141. When dop 14 and pothook 13 card are in the same place, the inboard of pothook 13 and the outside of dop 14 will contact each other, and the importance of this kind of contact has often been neglected to current ligature clamp the utility model discloses in, the inboard of special design pothook 13 is pothook plane 131, and the outside of dop 14 is dop plane 141 for these two

planes

131 and 141 can laminate each other, that is to say the utility model discloses a this kind of plane laminating design provides bigger area of contact, can be so that the ligature clamp is difficult to the slippage after the closure, has improved closed reliability greatly.

In addition, in another embodiment, the angle between the hook plane 131 and the first arc-shaped clamping arm 11 is designed to be 30-60 °, that is, in order to obtain a larger closing force and reliability, the angle of the hook 13 hooking the chuck 14 inwards is designed to be 30-60 °, and the angle is very small, so that the chuck 14 is basically difficult to be separated once being clamped into the inner side of the hook 13. Of course, the angle between the clip plane 141 and the guiding recess 18 is smaller than the angle between the hook plane 131 and the first arc-shaped clipping arm 11, otherwise, the clip 13 is too large to enter the hook 14.

It will be understood by those skilled in the art that since hook plane 131 is a plane and first arcuate clamping arm 11 is an arc, on a side projection plane, hook plane 131 can be projected as a straight line and first arcuate clamping arm 11 can be projected as an arc, and therefore, the included angle is defined as the angle enclosed by hook plane 131 and the tangent to first arcuate clamping arm 11 at the position where hook plane 131 intersects the side projection of first arcuate clamping arm 11. In fact, it can be seen from the figures that in order to avoid the above-mentioned angle being too large, the curvature of the first arcuate clamping arm 11 in the portion close to the plane 131 of the hook is gradually reduced, similar to a planar shape, and the above-mentioned angle is almost the angle between two straight lines as viewed in a side projection plane.

In another embodiment, the inner bottom of the catch 13 has a concave portion 20 which snap-fits with the bottom peak 30 of the guide groove 18, as can be seen in detail in fig. 4. The design further enables the top point part (the highest point 30) of the bottom of the groove 18 of the clamping head 14 positioned in the middle of the clamping head clamping body 16 to completely slide into the concave part 20 after the clamping head 14 is clamped to the inner side of the clamping hook 13, so that the clamping head 14 is basically firmly clamped in the concave part 20, the two clamping head clamping bodies 16 of the clamping head 14 clamp the outer side of the clamping hook 13, the clamping head 14 cannot shake left and right, and the closing force and the closing reliability of the ligation clamp are greatly improved.

It is to be understood by those skilled in the art that while the present invention has been described in terms of several embodiments, it is not intended that each embodiment cover a separate embodiment. The description is given for clearness of understanding only, and it is to be understood that all matters in the embodiments are to be interpreted as including all technical equivalents which are encompassed by the claims.

The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any equivalent changes, modifications and combinations that may be made by those skilled in the art without departing from the spirit and principles of the invention should be considered within the scope of the invention.
