Fig. 1 shows is perspective view according to the ligation clip of a specific embodiment of the present invention, as shown in the figure, the v-shaped structure that ligation clip of the present invention is formed in one on the whole, comprise a V-arrangement clamp 1, V-arrangement clamp 1 is formed by connecting by two arc jig arm 11,12, specifically, ligation clip of the present invention comprises that V-arrangement clamp 1, the first arc jig arm 11 that is made of first an arc jig arm 11 and the second arc jig arm 12 one and the free end of the second arc jig arm 12 are respectively grab 13 and dop 14.The first arc jig arm 11 be connected arc jig arm 12 junctions and have clamp and connect circular arc 2.
In the operation process, in order to stop blooding, the blood vessel (not shown) can be clamped between two arc jig arm 11,12 of V-arrangement clamp 1, by being snapped into, grab 13 make ligation clip closed on the dop 14, blood vessel firmly is clamped between two arc jig arm 11,12, described state can be referring to Fig. 2, and what wherein show is ligation clip closure view afterwards.
The first arc jig arm 11 has the anti-slop serrations 15 that layout is opened in two misarrangements with the second arc jig arm 12 relative inboards, be used for when ligation clip is held between two arc jig arm 11,12, by the anti-slop serrations 15 that is staggeredly arranged with the firm interlock of blood vessel, anti-hemostatic tube slippage.
The first arc jig arm 11 has a columned grab cramping body 17 at the end near grab 13, the second arc jig arm 12 has two opposed dop cramping bodies 16 at the end near dop 14, have the direction recess 18 towards grab between two dop cramping bodies 16, the outside of grab 13 has guiding surface 19.
The setting of grab cramping body 17 and dop cramping body 16 is for the process at closed ligation clip, utilize the instrument of Clip Applier and so on that grab cramping body 17 and dop cramping body 16 are clamped, then apply external force from two arc jig arm 11,12 inboard, lateral, so that grab 13 and dop 14 are closer to each other, the guiding surface 19 in grab 13 outsides slides along the direction recess 18 of dop 14 inboards, and grab 13 snaps on the dop 14 the most at last.
Operation for ease of the instrument of Clip Applier and so on, in in preferred an enforcement, grab cramping body 17 and dop cramping body 16 preferably have similar contour structures, from Fig. 1-5, can know and find out, grab cramping body 17 is for being symmetricly set in the outermost cylinder of grab 13, and dop cramping body 16 also is symmetricly set in the outermost of dop 14, and the side that dop cramping body 16 deviates from grab cramping body 17 also is the face of cylinder, the diameter on this face of cylinder equals the diameter of the cylinder of grab cramping body 17, like this so that the instrument of Clip Applier and so on can design identical clamp structure, be convenient to from two arc jig arm 11, when 12 inboard, lateral applies external force, the cylinder of the grab cramping body 17 of same diameter and the face of cylinder of dop cramping body 16 can be clamped.
In order to provide better closing force and so that the closure of ligation clip is more reliable, the side that dop 14 deviates from grab 13 has a dop plane 141, the inboard of grab 13 has the grab plane 131 that can fit with dop plane 141.When dop 14 and grab 13 are stuck, the outside of the inboard of grab 13 and dop 14 will be in contact with one another, existing ligation clip has often been ignored the importance of this contact, in the present invention, the inboard of special design grab 13 is grab plane 131, and the outside of dop 14 is dop plane 141, so that these two planes 131 and 141 can be bonded to each other, that is to say that this plane applying design of the present invention provides larger contact area, can so that be not easy slippage after the ligation clip closure, greatly improve closed reliability.
In addition, in another specific embodiment, angle between grab plane 131 and described the first arc jig arm 11 is designed to 30-60 °, that is to say, in order to obtain larger closing force and reliability, the angle that design grab 13 inwardly catches on dop 14 is 30-60 °, and angle is very little, basically just is difficult to break away from so that in a single day dop 14 snaps onto grab 13 inboards.Certainly, the angle between dop plane 141 and the direction recess 18 also is less than grab plane 131 and states angle between the first arc jig arm 11, otherwise dop 13 too greatly has been difficult to enter grab 14 inboards.
Those skilled in the art are to be understood that, because grab plane 131 is planes, and the first arc jig arm 11 is arcs, then on lateral projection's face, grab plane 131 can project into straight line, and the first arc jig arm 11 can project into a camber line, therefore, what above-mentioned angle defined is the crossing position of lateral projection of grab plane 131 and the first arc jig arm 11, by the folded angle of the tangent line of grab plane 131 and the first arc jig arm 11.In fact, as can be seen from the figure excessive for fear of above-mentioned angle, the first arc jig arm 11 diminishes gradually at the part radian near grab plane 131, is similar to flat shape, and from lateral projection's face, above-mentioned angle almost is the angle of two straight lines.
In another specific embodiment, the inside bottom of grab 13 has the concave shaped portion 20 that a bottom peak 30 with direction recess 18 is clasped, and specifically can see Fig. 4 for details.This design further so that dop 14 snap into after the inboard of grab 13, so that being positioned at the apex portion (peak 30) of the bottom of the groove 18 in the middle of the dop cramping body 16, dop 14 can all slide into concave shaped portion 20 inside, so that dop 14 can firmly be clamped in the concave shaped portion 20, and two dop cramping bodies 16 of dop 14 are clamped grab 13 outsides, so that dop 14 fully can't double swerve, greatly improved closing force and the closed reliability of ligation clip.
What Fig. 5 showed is that ligation clip of the present invention is looked view by the throwing of the side before the Clip Applier closure, as shown in the figure, go for apparatus under the various varying environments for the ease of ligation clip, in illustrated specific embodiment, the distance of setting especially between the outermost mid point that grab cramping body 17 and dop cramping body 16 and clamp connect circular arc 2 is identical.Specifically, namely throw in the side of ligation clip shown in Figure 5 and look under the state, the center of circle of the cylinder of grab 13 is connected the center of circle that distance between the outermost mid point of circular arc 2 equals the face of cylinder of dop 14 and arrives distance between clamp connection circular arc 2 mid points with clamp.
Should be noted that, above-mentioned restriction is actually in order to illustrate, two arc jig arm 11 that consist of ligation clip and 12 cramping body 17,16 identical substantially to the length of the bottom of V-structure, owing to being difficult to find other more suitable expression way from structrual description, the present invention has adopted the limiting mode of above-mentioned feature, and those skilled in the art should be easy to reference to the accompanying drawings just can understand that above-mentioned restriction is clear and complete.
Under above-mentioned design, after Clip Applier 5 is with the ligation clip clamping, grab cramping body 17 is connected identical apart from the distance of the outermost mid point of clamp connection circular arc 2 with the dop cramping body, so that the first arc jig arm 11 of ligation clip and the second arc jig arm 12 can forming V-shape state integral body be positioned at the centre position of Clip Applier 5, be unlikely to make the first arc jig arm 11 or the second arc jig arm 12 to depart from the intermediate line of Clip Applier 5, so just be unlikely to make between two jig arm of ligation clip and the Clip Applier 5 to produce excessive extruding force, cause ligation clip stuck between Clip Applier 5.
For example, suppose that grab cramping body 17 is connected the outermost mid point of circular arc 2 with clamp distance is connected the distance between the outermost mid point of circular arc 2 with clamp greater than dop cramping body 16, after then ligation clip is clamped by Clip Applier 5, ligation clip is partial to right side shown in Figure 5 with integral body, crimp might be so that occur between the second arc jig arm 12 and the Clip Applier 5 in the result, thereby so that stuck in Clip Applier 5, being difficult to of ligation clip break away from.
This design feature of the present invention is so that no matter ligation clip can for different surgical environments, need the ligation clip of which kind of size, as long as follow this characteristic Design, can well cooperate with apparatus, easily operation is used, therefore, this design of the present invention possesses better versatility.
Should be noted that, in the design of above-described embodiment, owing to setting the cramping body 17 of two arc jig arm 11 and 12,16 is identical substantially to the length of the bottom of V-structure, therefore ligation clip can be positioned at the centre position of Clip Applier 5, in addition, another benefit of doing like this is can be so that Clip Applier 5 adopts symmetrical clamp structure, and, because the front mentions that grab cramping body 17 is identical with the diameter of dop cramping body 16, so, no matter Clip Applier 5 towards which direction can use in the operation process, greatly facilitates the operation of operation, saved the time, the error that is unlikely to act hurriedly in a messy situation causes a serious accident.
Although it will be appreciated by those skilled in the art that the present invention is that mode according to a plurality of embodiment is described, and is not that each embodiment only comprises an independently technical scheme.Narration like this only is for the sake of clarity in the description; those skilled in the art should make description as a wholely to be understood, and regard technical scheme related among each embodiment as the mode that can mutually be combined into different embodiment understand protection scope of the present invention.
The above only is the schematic specific embodiment of the present invention, is not to limit scope of the present invention.Any those skilled in the art, the equivalent variations of doing under the prerequisite that does not break away from design of the present invention and principle, modification and combination all should belong to the scope of protection of the invention.
