The specific embodiment
For the technical characterictic of utility model, object and effect being had more clearly, understand, now contrast accompanying drawing the specific embodiment of the present utility model is described, in each figure, identical label represents the identical or structural similarity of structure but the identical parts of function.
For making drawing succinct, in each figure, only schematically shown the part relevant to this utility model, they do not represent that it is as the practical structures of product.In addition, for making drawing succinctly be convenient to understand, in some figure, there are the parts of same structure or function, only schematically illustrated one of them, or only marked one of them.
In this article, " one " not only represents " only this ", also can represent the situation of " more than one ".
Fig. 2 is in order to illustrate a kind of structure of exemplary embodiment of the knee joint cavity implantation device of Zhi Liao popliteal cyst.Fig. 3 is a surperficial schematic diagram of the knee joint cavity implantation device in Fig. 2, and Fig. 4 is along the sectional structure schematic diagram of II-II direction in Fig. 2 and in order to the work process of catch to be described.The knee joint cavity implantation device of Zhi Liao popliteal cyst comprises a knee joint cavity diaphragm seal 12 and a catch 16 as shown in Figure 2, Figure 3, Figure 4, on knee joint cavity diaphragm seal 12, offer a through hole 14, the neighboring area of catch 16 is fixed on knee joint cavity diaphragm seal 12, make catch 16 can hide through hole 14, and the junction of the neighboring area of catch 16 and knee joint cavity diaphragm seal 12 has opening 162, can make catch 16 and knee joint cavity diaphragm seal 12 form a flowing lumen 20.
Above-mentioned knee joint cavity implantation device can be implanted in patient's knee joint cavity 80, refer to Fig. 1, with Zhi Liao popliteal cyst, for example, in operation process, can first utilize arthroscope to find knee joint cavity 80 Yu the passage 82 between popliteal cyst 90, with knee joint cavity diaphragm seal 12 seal channels 82, make through hole 14 corresponding to passage 82, and make a side that knee joint cavity diaphragm seal 16 has catch 16 towards knee joint cavity 80.Liquid direct motion in popliteal cyst 90 is interior when mobile to knee joint cavity 80 like this, can promote catch 16 and open through hole 14 with respect to through hole 14 motions, and form flowing lumen 20, as shown in a figure in Fig. 4, now through hole 14 is communicated with opening 162, be communicated with liquid in passage 82 ， popliteal cysts 90 along the direction of arrow in the figure direct motion to knee joint cavity 80 is interior, flow; As shown in b figure in Fig. 4, liquid in knee joint cavity 80 drives in the wrong direction interior when mobile Xiang popliteal cyst 90, as shown by arrows in FIG., liquid can promote catch 16 and hide through hole 14, now flowing lumen 20 disappears, passage 82 is sealed, to stop the liquid in knee joint cavity 80 to drive in the wrong direction interior mobile Xiang popliteal cyst 90.Catch 16 and through hole 14 have been realized the effect of a check valve, like this after operation, can avoid liquid that the liquid in knee joint cavity drives in the wrong direction in the interior mobile ， Er popliteal cyst 90 of popliteal cyst 90 can antegrade flow in knee joint cavity 80, thereby avoid the recurrence of popliteal cyst 90.
As shown in Figure 2, Figure 3, Figure 4, the neighboring area of catch 16 is that partial fixing is on knee joint cavity diaphragm seal 12, thereby form opening 162, said " fixing " both comprised that situation about being completely fixed also comprised the situation of partial fixing herein, certainly the difference needing according to design, also can make the neighboring area of catch 16 be completely fixed on knee joint cavity diaphragm seal 12, and opening 162 is opened on catch 16.
Fig. 5 is in order to illustrate fixed structure in the articular cavity of the implantation device back to catch one side of another kind of exemplary embodiment of knee joint cavity implantation device of Zhi Liao popliteal cyst.Fig. 6 is the sectional structure schematic diagram along III-III direction in Fig. 5.Below in conjunction with Fig. 5, Fig. 6, introduce the another kind of exemplary embodiment of the knee joint cavity implantation device of Zhi Liao popliteal cyst.As shown in the figure; on knee joint cavity diaphragm seal 12, in a side of catch 16, also there are a plurality of flexure strips 18; each flexure strip 18 has a link 182 that can be connected with knee joint cavity diaphragm seal 12, and the free end 184 that can draw close or separate with respect to knee joint cavity diaphragm seal 12.Can first make the free end 184 of flexure strip 18 away from knee joint cavity diaphragm seal 12, for example make flexure strip 18 perpendicular to knee joint cavity diaphragm seal 12, as shown in Figure 6, in operation process, passage 82 Shen Ru by the free end of flexure strip 18 184 from Fig. 1 are Zhi popliteal cyst 90, knee joint cavity diaphragm seal 12 is abutted on knee joint cavity 80 inwalls, and the free end 184 of flexure strip 18 can be drawn close (as shown in the dotted line in Fig. 6) to knee joint cavity diaphragm seal 12, be in actual operation, flexure strip 18 can be Dinged on popliteal cyst 90 inwalls by Gu, to strengthen the fixed effect of knee joint cavity implantation device.
On knee joint cavity diaphragm seal 12 in Fig. 5, Fig. 6, have four flexure strips 18, and four flexure strips 18 link 182 by separately connects as one, the fixed effect of said structure is stable, easily manufactures.Certain difference as required, quantity and the structure of flexure strip are not limited to shown in figure.
The one-way valve structures of utilizing catch and through hole to form, knee joint cavity implantation device can avoid the hydrops in knee joint cavity to drive in the wrong direction in popliteal cyst flowing the liquid direct motion in Yun Xu popliteal cyst to flow to knee joint cavity, and You helps the recurrence of Bi Mian popliteal cyst, improves therapeutic effect.
In this article, " schematically " expression " is served as example, example or explanation ", any diagram, the embodiment that are described in this article " schematically " should be interpreted as a kind of preferred or have more the technical scheme of advantage.
Be to be understood that, although this description is described according to each 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, 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.
