The form of mouth, can improve structural strength, eliminate anastomotic stoma and clamp-on the hidden danger that breach affects to heal, while the presence of breach can
To facilitate the minimally invasive opening from stomach wall to be squeezed into, the size of minimally invasive opening can be reduced, be conducive to the healing being open, be mitigated and suffer from
Person's pain.
Certainly, in another specific embodiment, the annulus 41 of anastomat 40 can also be configured without the form of breach,
As shown in figure 9, it is shown that the stereochemical structure of the vesicourethral anastomat of another specific embodiment of the invention is shown
It is intended to.Do not have structural strength jaggy better, it is not easy to fracture.
Further, in a further advantageous embodiment, from Fig. 5-6 as can be seen that the annulus 41 of the present invention can be by straight
The different thick rod 412 in footpath and the interval of thin rod 413 are formed by connecting, and the benefit of thickness spacing structure can be the volume for reducing material,
It is easy to the position disintegrate from the thin rod 413 of structural weak, and the small volume after disintegrate, it is easy to excrete.It is simultaneously guarantee
Structural strength, preferred spike 411 and hook foot 42 are connected with thick rod 412, i.e., the spike 411 and hook foot 42 of main stress are respectively provided with
On the larger thick rod 412 of structural strength, it is unlikely to that stress is excessive in operative process so that anastomat 40 fractures.Meanwhile,
From fig. 6, it can be seen that it is preferred that breach 414 be located at two adjacent thick rods 412 between, i.e., breach 414 disconnect thin rod be located
At position, breach so can be as far as possible reduced for the weakening of circular ring structure intensity.
In addition, from Fig. 9 it can also be seen that the annulus 41 of the present invention can also be that diameter identical circulus is (no thick
Rod and the structure of thin rod interval connection), can as shown in Figure without breach, it is also possible to which similar previous embodiment is arranged like that
Breach.
Further, Fig. 9 is shown the vertical of the vesicourethral anastomat of another specific embodiment of the invention
Body structural representation, the population structure design of anastomat 40 in figure is substantially the same as in the previous example, and difference is, in figure
Reinforcing connector 415 is connected between hook foot.Reinforce shown in Fig. 9 connector 415 in the latticed agnail 421 for being arranged on hook foot with
On part, effect is the structural strength reinforced between hook foot 42, and stress fractures when preventing that hook foot stress is excessive to be used.Certainly,
In a specific embodiment, described to reinforce the circle annulus that connector 415 be connecting hook foot bottom, its structure is similar to
In the anastomat annulus 41 on top.Anastomat annulus 41 is different by diameter as being as shown in the previous embodiment in figure
Thick rod and thin rod interval are formed by connecting, or diameter identical circulus, can not as shown in Figure have breach,
Previous embodiment can be similar to breach is set like that.
Further, if the latticed reinforcing connector 415 in Fig. 9 further encrypted so that grid
The grid of the reinforcing connector 415 of shape disappears, then embodiment illustrated in fig. 9 can just be formed like the structure shown in Figure 10, i.e.,
Tubular structure has been downwardly extending from the annulus 41 of anastomat 40.Certainly, embodiment illustrated in fig. 10 can also be on annulus 41
With breach 414, and for ease of compression, breach 414 is extended into along the length direction of the barbed connector 42 of tubular structure
Breach.
Further, the anastomat hook for the ease of the present invention is firmly difficult for drop-off, in the embodiment shown in fig. 12, can
To arrange multiple outside agnails 421 along the length direction of barbed connector 42, for example, can be along the tubular structure of Figure 10
The outer surface of barbed connector 42 be covered with agnail 421, it is also possible to along length on each the hook foot shown in Fig. 5,6,8,9,11
