The specific embodiment
For technical characterictic of the present utility model, object and effect being had more clearly, understand, now contrast accompanying drawing the specific embodiment of the present utility model is described.Wherein, identical parts adopt identical label.
What Fig. 1 showed is according to the perspective view of the ligation clip of a specific embodiment of the present utility model, as shown in the figure, the v-shaped structure that ligation clip of the present utility model is formed in one on the whole, comprise a V-arrangement clamp 1, V-arrangement clamp 1 is by two arc jig arm 11, 12 are formed by connecting, specifically, ligation clip of the present utility model comprises by a first arc jig arm 11 and a V-arrangement clamp 1 that the second arc jig arm 12 one form, the free end of the first arc jig arm 11 and the second arc jig arm 12 is respectively grab 13 and dop 14, the first arc jig arm 11 has clamp with the second arc jig arm 12 junctions and is connected circular arc 2.
In operation process, in order to stop blooding, ligation clip can be held between V-arrangement clamp 1, by grab 13 being snapped on dop 14, make ligation clip closed, blood vessel is firmly 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 a columned grab cramping body 17 near grab 13 one end, the second arc jig arm 12 has two opposed dop cramping bodies 16 near dop 14 one end, between two dop cramping bodies 16, have the direction recess 18 towards grab, 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 from inner side, two arc jig arm 11,12 laterals, apply external force, make grab 13 and dop 14 closer to each other, the guiding surface 19 in grab 13 outsides slides along the direction recess 18 of dop inner side, and grab 13 snaps on dop 14 the most at last.
For better closing force being provided and making the closure of ligation clip more reliable, the side that dop 14 deviates from grab 13 has a dop plane 141, and the inner side 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 inner side 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 this utility model, the inner side of special design grab 13 is grab plane 131, and the outside of dop 14 is dop plane 141, make these two planes 131 and 141 can be bonded to each other, that is to say that this plane laminating design of the present utility model provides larger contact area, can, so that be not easy slippage after 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, once make dop 14 snap onto grab 13 inner sides, is substantially just difficult to depart from.Certainly, the angle between dop plane 141 and direction recess 18 is also less than grab plane 131 and states the angle between the first arc jig arm 11, otherwise dop 13 too greatly has been difficult to enter grab 14 inner sides.
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, on Ze lateral projection 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 grab plane 131 and the first arc jig arm 11 lateral projection, 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 on flat shape ，Cong lateral projection face and sees, above-mentioned angle is almost the angle of two straight lines.
Fig. 3 shows is that side before ligation clip closure of the present utility model throws that to look state generalized section (clear for representing, omitted hatching), as shown in Figure 1,3, for the ease of ligation clip, go for the apparatus under various varying environments, in illustrated specific embodiment, the special top, inner side of setting grab 13 is a to the length bottom it, the bottom peak 30 of the direction recess 18 of dop 14 is b to the length between the outermost mid point of clamp connection circular arc 2, wherein, the ratio of b and a is between 8～12.Namely in the side of the ligation clip shown in Fig. 3, throw and look under state, the ratio of the length of the length of the second arc jig arm 12 at dop 14 places and the inner side plane of grab 13 is between 6～15.For ease of explanation, the length of definition grab plane 131 is the top, inner side of described grab 13 to the length a of its bottom.
It should be pointed out that this utility model has adopted the limiting mode of above-mentioned feature owing to being difficult to find other more suitable expression way from structrual description, those skilled in the art should be easy to just can understand that above-mentioned restriction is clear and complete with reference to the accompanying drawings.
Under above-mentioned design, in closed under the instrumental purpose of ligation clip at Clip Applier and so on, the guiding surface 19 in grab 13 outsides slides along the direction recess 18 of dop inner side, thereby cause the length crimp gradually of the second arc jig arm 12 at dop 14 places, it is large that radian becomes, and the bottom peak 30 of groove 18 shortens to the straight length between the outermost mid point of clamp connection circular arc 2.When the bottom of groove 18 peak 30 arrives the top, inner side of grab 13, the second arc jig arm 12 distortion reach at utmost, afterwards, dop 14 slips into the inner side of grab 13, dop plane 141 moves along the length direction of grab plane 131, until the bottom peak 30 of groove 18 arrives the inside bottom of grab 13, grab 13 snaps on dop 14 the most at last.Wherein, for ease of explanation, dop plane 141 length corresponding with the length of grab plane 131 is defined as the length d of dop plane 141, in a specific embodiment, in order to make dop plane 141 and grab plane 131 reach best laminating effect, larger contact area is provided, can designs the length a that makes the length d of the dop plane 141 corresponding with the length of grab plane 131 be more than or equal to grab plane 131.
Visible in the description of the above-mentioned closing course of ligation clip, if the length of grab plane 131 is oversize comparatively speaking, so in closing course, the degree that the length of the second arc jig arm 12 need to be compressed will be very large, will make like this radian of the second arc jig arm 12 become very large, cause the part of the second arc jig arm 12 bendings inconsistent with the first arc jig arm 11, if withstanding too greatly the second arc jig arm 12, the first arc jig arm 11 intensity make it cannot continue distortion, finally may cause the second arc jig arm 12 to fracture, or the first arc jig arm 11 also likely be can't hold out against the distortion of the second arc jig arm 12, cause the first arc jig arm 11 to fracture.On the other hand, if the length of grab plane 131 is too short comparatively speaking, after closure, the diastrophic amplitude of the second arc jig arm 12 is too little so, and the chucking power that causes ligation clip is too little and blood vessel firmly cannot be clamped, and does not reach the object of hemostasis.
Therefore, in the present embodiment, no matter be which kind of surgical environments, no matter the ligation clip of which kind of size, is the design between 6～15 as long as follow the ratio of b and a, can obtain best chucking power and clip and in closing course, be unlikely to damage.And existing clip design is owing to not knowing this rule, often need repetition test, and the clip of different sizes also to carry out different designs, cost is too high.Therefore, the creationary discovery of this utility model has also utilized above-mentioned this design rule, can realize industrial-scale production, has reduced production and design cost.
In addition, equally referring to Fig. 1,3, in order to realize best chucking power, the inside bottom of definition grab 13 is c to the length between the outermost mid point of clamp connection circular arc 2, and wherein the ratio of b and c is between 1.1～1.3.Same, owing to being difficult to find other more suitable expression way from structrual description, this utility model has adopted the limiting mode of above-mentioned feature, and those skilled in the art should be easy to just can understand that above-mentioned restriction is clear and complete with reference to the accompanying drawings.
Under above-mentioned design, what in fact limit is the length relation of the first arc jig arm 11 and the second arc jig arm 12, and namely the length of the second arc jig arm 12 is larger than the length of the first arc jig arm 11.In fact this saying is a kind of general description of being convenient to understanding, and precise definition still will be with reference to accompanying drawing with aforesaid describing mode.Above-mentioned restriction design principle is, in the time of ligation clip closure, due to relatively long, can there is certain distortion after closure in the second arc jig arm 12, this distortion can make the first arc jig arm 11 and second arc jig arm 12 is relative draws close, thereby can obtain better chucking power.Certainly, if the length of the Length Ratio first arc jig arm 11 of the second arc jig arm 12 is much larger, will cause the second arc jig arm 12 be out of shape excessive and rupture, therefore the ratio that limits b and c is between 1.1～1.3, to be a kind of invention embodiment of creativity, can realize industrial-scale production, reduce and produce and design cost.
Ligation clip provided by the utility model, its structural design has been followed certain rule, and which kind of surgical environments no matter make is, no matter the ligation clip of which kind of size, as long as follow the design of this rule, can obtain best chucking power and clip and in closing course, be unlikely to damage.
