The specific embodiment
Below in conjunction with each embodiment shown in the drawings, this utility model is elaborated; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skills are according to these embodiment institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
The word of described expression position and direction, is all to using exercises on apparatus author as reference in this utility model, and one end of close operator is near-end, away from one end of operator, is far-end.
As shown in Figure 1 and 2, linear anastomat 100 of the present utility model comprises the nail anvil connecting rod 13 that opposing parallel arranges, and it comprises line part 131 and the bending section 132 being fixedly connected with line part 131.The near-end of this nail anvil connecting rod 13 is also provided with power firing lock 10, and far-end is provided with fitting mechanism, and wherein the effect of fitting mechanism is closed tissue.Power firing lock 10 is also provided with operating grip, and it is for controlling the fitting mechanism operation that coincide.
Particularly, described fitting mechanism comprises nail anvil 15, the nail bin 14 that can move with respect to nail anvil 15.Wherein, nail anvil 15 is fixedly connected with the bending section 132 of described nail anvil connecting rod 13, and nail bin 14 is between nail anvil connecting rod 13, and the work surface of nail anvil 15 and nail bin 14 is relative and be arranged in parallel.
Described fitting mechanism also comprises the elastic component 16 being arranged between described nail anvil 15 and nail bin 14, and elastic component 16 is for the auxiliary tissue that flattens operation process.Described elastic component 16 comprises first end and the second end, wherein first end arranges near described nail anvil 15 or nail bin 14, correspondingly, the second end of elastic component 16 arranges near described nail bin 14 or nail anvil 15, curvature when described elastic component 16 distance curvature farthest time between described nail anvil 15 and nail bin 14 is greater than described nail anvil 15 and nail bin 14 and matches.
Described fitting mechanism also comprises the translation groove 17 being arranged between described nail bin 14 and nail anvil 15, and the first end of described elastic component 16 and described translation groove 17 are slidably connected.Particularly, translation groove 17 arranges near described nail anvil 15, and correspondingly, in present embodiment, the first end of elastic component 16 also arranges near the nail anvil 15 of fitting mechanism.Certainly the position of translation groove 17 is not what fix, and as another kind of embodiment, translation groove 17 also can arrange near nail bin 14, and now the second end of elastic component 16 extend in translation groove 17, and then can realize identical technique effect.
Described fitting mechanism also comprises carriage assembly 18, arranges accordingly with described translation groove 17, and carriage assembly 18 arranges near described nail bin 14, and correspondingly, the second end of described elastic component 16 connects described carriage assembly 18.Described carriage assembly 18 comprises the assembly pulley 19 be arrangeding in parallel, and the other end of described elastic component 16 stretches between the adjacent pulleys of assembly pulley 19.
Further, as a kind of concrete embodiment, this carriage assembly 18 comprises bearing and also perpendicular the first rotating shaft being fixedly connected with and the second rotating shaft between bearing.Particularly, the first rotating shaft and the second rotating shaft are positioned at the top of nail bin 14.Described carriage assembly 18 is pivotally connected with nail anvil connecting rod 13, and assembly pulley 19 is installed on it, and assembly pulley 19 comprises and is installed on the first pulley 191 in the first rotating shaft and is installed on the second pulley 192 in the second rotating shaft.The second end of described elastic component 16 extend between the first pulley 191 and the second pulley 192.In addition, the angle scalable of described carriage assembly 18 as required, carriage assembly 18 also can be pivotally connected by damping structure and nail anvil connecting rod 13 certainly.When installing or change nail bin 14, can first carriage assembly 18 be rotated to certain angle to nail anvil 15 directions, thereby reserve enough working places for installing or change nail bin.
As shown in Figure 3, further, described elastic component 16 is formed with a gap 160 in its longitudinal direction, thereby makes elastic component 16 form one " U " shape.The one end that extend into the elastic component 16 between the first pulley 191 and the second pulley 192 is formed with 161 one-tenth of 161，Gai extensions, an extension curl shape.The extension 161 of curl shape has certain position-limiting action.Now, the extension 161 of the curl shape of elastic component 16 arranges near described nail bin 14.In addition, extend on the one end of the elastic component 16 in translation groove 17 and convex with card convex 162, this card convex 162 can make elastic component 16 Stable sliding in translation groove 17, and from translation groove 17, ejects can be because of elastic component generation elastic deformation time.Because described elastic component 16 is " U " type, the quantity of described translation groove 17 is correspondingly two, to coordinate the structure of the elastic component 16 of " U " type.
Further, described the first pulley 191 and the second pulley 192 can offset with elastic component 16, make like this elastic component 16 to slide along the first pulley 191 and the second pulley 192, have facilitated the motion of elastic component 16.
As shown in Fig. 4 ~ 5, the work process of linear anastomat of the present utility model is such, first, the tissue of needs operation is put between elastic component and nail anvil, and adjust its position, be organized in the process entering between nail anvil and nail bin, due to the existence of elastic component, make originally stacking organize slowly flattened.Now, the curvature of elastic component is maximum, and control operation handle, makes the relative nail anvil of nail bin do move toward one another, and the distance between nail bin and nail anvil is dwindled gradually.The curvature of the elastic component between the two also correspondingly reduces gradually, elastic component is pressed in tissue gradually, make the tissue between elastic component and nail anvil again flattened, until arriving, apparatus can pull the trigger state like this, tissue is flattened completely, nail bin just fully touches tissue, and it is minimum that the curvature of elastic component reaches.Finally, when described nail anvil and nail bin match, elastic component and described nail anvil, nail bin are parallel, do not affect the gap between nail anvil and nail bin, effectively avoided because of after tissue directly contacts with nail bin, repeatedly closed or open and the anastomat that occurs is malfunctioning or fall to follow closely equivalent risk.
Linear anastomat of the present utility model has guaranteed that nail bin can just fully contact with it after needs press from both sides the tissue flattening that close, the generation of avoided malfunctioning in the closure repeatedly of anastomat or opening procedure, falling to follow closely equivalent risk, and be not subject to the restriction of level angle, easy to use.
To those skilled in the art, obviously this utility model is not limited to the details of described one exemplary embodiment, and in the situation that not deviating from spirit of the present utility model or basic feature, can realize this utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described explanation, is therefore intended to include in this utility model dropping on the implication that is equal to important document of claim and all changes in scope.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this description is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of description is only for clarity sake, those skilled in the art should make description as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
