The specific embodiment
Below in conjunction with drawings and Examples, the present invention will be described in more detail.
As shown in Figure 1, the conical puncture draw point 1 that logical stapling apparatus uses again of proctatresia, it is processed by rustless steel.
As shown in Figure 2, the dilating catheter 2 that the head end that logical stapling apparatus uses again of proctatresia is conical hollow, axially be provided with the conduit medium pore 21 of perforation along dilating catheter 2, the internal diameter of conduit medium pore 21 is greater than the external diameter of the draw point 1 that punctures, and to allow to puncture, draw point 1 passes; The outer dia of dilating catheter 2 need to be designed with different size according to clinical.
As shown in Figure 3, the guiding seal wire 3 of logical stapling apparatus again of proctatresia, guiding seal wire 3 is made up of rustless steel steel wire and the polytetrafluoroethylene floor that is coated on outside rustless steel steel wire, and guiding seal wire 3 external diameters are less than the internal diameter of conduit medium pore 21, to allow guiding seal wire 3 to pass.
As shown in Figure 4, with the sub-magnet 4 of spindle of guiding tube 42, be provided with in the central the hole 41 of running through along the major axis of sub-magnet 4, in hole 41, interior close-fitting has guiding tube 42, and guiding tube 42 is rustless steel, and the internal diameter of guiding tube 42 is greater than the external diameter of dilating catheter 2.
As shown in Figure 5, female magnet 5, main body is cylindrical, there is porus excretorius 52 upper surface with concave surface 51, central authorities, porus excretorius 52 connects the end and the columniform lower surface of concave surface 51, the internal diameter of porus excretorius 52 is greater than the external diameter of guiding tube 42, and the radian of concave surface 51 and size are mated identical with radian and the size of sub-magnet 4 lower end projections completely.
As shown in Figure 6, the state profile after sub-magnet 4 and the 5 para-position adhesives of female magnet.Guiding tube 42 is inserted in porus excretorius 52.
Operation principle of the present invention is: as shown in Figure 7, first puncture into the cecum of rectum 7 through skin 6 by puncture draw point 1, then, as shown in Figure 8, dilating catheter 2 is inserted in to the outer puncture path of facing of puncture draw point 1 to be expanded, again as shown in Figure 9, keep dilating catheter 2 invariant positions, exit puncture draw point 1, send into the cecum of guiding seal wire 3 to rectum 7 through the conduit medium pore 21 of dilating catheter 2, then as shown in figure 10, exit dilating catheter 2, send into sub-magnet 4 along guiding seal wire 3, then as shown in figure 11, sub-magnet 4 is delivered to rectum 7 lower ends, send into female magnet 5 along guiding seal wire 3 as shown in figure 12, sub-magnet 4 and the 5 para-position adhesives of female magnet, then as shown in figure 13, pull out guiding seal wire 3, internal rectum feces 8 can excrete by the guiding tube 42 on sub-magnet 4, finally, as shown in figure 14, sub-magnet 4 comes off after inhaling mutually squeezing a period of time with female magnet 5 naturally, anus 9 can be set up.
By puncture draw point, the location of conduit and the guiding of seal wire, utilize the permanent magnet of two special shapes can realize the logical and identical again of locking anus.Adopt this device, simple to operate, minimum to anal external sphincter damage, more logical and match result is reliable, and at anal canal under serious contaminated environment, more can embody the advantage of this device.In addition, because the existence of guiding tube 42 can realize after operation defecation immediately, and can expand voluntarily in early days after surgery anus.
