Detailed description of the invention
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiments do not limit the present invention, the structure that those of ordinary skill in the art makes according to these embodiments or conversion functionally are all included in protection scope of the present invention.
Please refer to Fig. 3 to the better embodiment that Figure 4 shows that screw barrel component 1 of the present invention.Described screw barrel component 1 is applied on a cylinder type anastomat (not shown), thus the invention still further relates to a kind of cylinder type anastomat; The described screw barrel component 1 that this cylinder type anastomat is included housing (not shown) and is fixedly connected by a retainer ring (not shown) with housing.
Shown in composition graphs 3 and Fig. 4, screw barrel component 1 of the present invention comprises the nail barrel 11 that fixes with the housing of cylinder type anastomat and to be arranged in nail barrel 11 and the nail bin 12 fixed with nail barrel 11.Described nail barrel 11 is provided with the clasp groove 111 from outside depression.Described nail bin 12 be provided with outwards expose upper lateral part 121, outside upper lateral part 121 along the axially extended adjutage of nail barrel 11 122 and from adjutage 122 inwardly projection with the snap projection 123 with described clasp groove 111 phase clasp.Be inconvenient to the operation of performing the operation to prevent the undue emergence of described adjutage 122 and snap projection 123 from going out nail barrel 11 outer surface, described nail barrel 11 is also provided with and caves in from outside and the depressed part 112 be connected along nail barrel 11 axial direction with described clasp groove 111.The adjutage 122 of described nail bin 12 is contained in described depressed part 112.Carry out smoothly in order to what perform the operation and can not form injury to human body cast tissue (not shown), the outer surface of described adjutage 122 can be set to the outer surface of nail barrel 11 in the same plane.In addition, for strengthening the fixing steadiness between nail barrel 11 and nail bin 12, nail bin 12 of the present invention is provided with several along the equally distributed described adjutage 122 of nail barrel 11 circumferencial direction and described snap projection 123.
As seen from the above, the present invention passes through at nail barrel 11 arranged outside clasp groove 111, nail bin 12 is arranged the adjutage 122 that extends outside its upper lateral part 121 and the snap projection 123 from adjutage 122 inwardly projection and described clasp groove 111 phase clasp, the mode of exterior snap fixing is adopted to be fixed together by nail barrel 11 and nail bin 12, adjutage 122 can be supplied to the certain elasticity of snap projection 123 simultaneously, thus facilitate the assembly and disassembly of nail barrel 11 and nail bin 12, and the destruction of part can not be caused.
A series of detailed description listed is above only illustrating for feasibility embodiment of the present invention; they are also not used to limit the scope of the invention, all do not depart from the skill of the present invention equivalent implementations done of spirit or change all should be included within protection scope of the present invention.
