On above-mentioned traction fiber, be with sleeve pipe, and a telescopic end is fixed on the top of hollow mobile jib, and the telescopic other end passes with the bottom of traction fiber from the hollow mobile jib.
The other end of above-mentioned conduit passes from the top of hollow mobile jib.
In the import of above-mentioned conduit, check valve is installed.
Above-mentioned strut comprises internal overarm support and outer strut, and an end of internal overarm support is hinged on the top of hollow mobile jib, and the other end of internal overarm support is hinged with an end of outer strut, and the other end of outer strut is hinged on the cross bar.
Be rotated counterclockwise the interior stopping means that surpasses 35 degree at the restricted internal overarm support in the hinged place of above-mentioned internal overarm support and hollow mobile jib.
Restricted outer strut is rotated counterclockwise the outer stopping means of spending above 45 in the above-mentioned internal overarm support and the hinged place of outer strut.
The upper end of above-mentioned hollow mobile jib is that lower end that seal or the hollow mobile jib is that all seal at two ends that seal or hollow bar.
The outside, bottom at above-mentioned hollow mobile jib is equipped with holder.
Structural representation when accompanying drawing 1 is in off working state for this utility model embodiment 1 or embodiment 2,
Accompanying drawing 2 is that the sectional structure sketch map is amplified in the part of the ring-shaped gasbag when embodiment 1 is in running order in the accompanying drawing 1 etc.,
Accompanying drawing 3 is that the sectional structure sketch map is amplified in the part of the ring-shaped gasbag when embodiment 2 is in running order in the accompanying drawing 1 etc.,
Coding in the accompanying drawing is respectively: 1 is ring-shaped gasbag, and 2 are the support pad, and 3 is cross bar, and 4 is strut, and 5 is the hollow mobile jib, 6 is conduit, and 7 is traction fiber, and 8 is sleeve pipe, and 9 are import, and 10 is check valve, 11 is internal overarm support, and 12 is outer strut, and 13 is interior stop, and 14 is outer stop, and 15 is holder.
Below in conjunction with embodiment and accompanying drawing this utility model is further described:
Shown in attached Fig. 1 and 2, there is support pad 2 ring-shaped gasbag 1 inboard of this liver second hepatic portal occlusion device, on support pad 2, be fixed with cross bar 3, one end of strut 4 is hinged on the cross bar 3, the other end of strut 4 is hinged on the top of hollow mobile jib 5, one end of conduit 6 communicates with ring-shaped gasbag 1, and the other end of conduit 6 feeds in the hollow mobile jib 5.When carrying out operation on liver: at first, inserting this utility model by great saphenous vein or femoral vein to postcava is this liver second hepatic portal occlusion device, and to make its head be that ring-shaped gasbag 1 is positioned at the second hepatic portal place; Inflate or liquid in ring-shaped gasbag 1 by conduit 6 then, ring-shaped gasbag 1 is expanded and compressing live hepatic vein at venacaval inlet so can stop the hepatic vein blood flow, and the central hollow of the ring-shaped gasbag after expanding part still can make blood continue circulation and not occlude blood circulation.
For the central hollow part that makes the ring-shaped gasbag after the expansion relatively large, thereby more help blood circulation, as shown in Figure 1, an end of traction fiber 7 is fixed on the cross bar 3, and the other end feeds hollow mobile jib 5 and pass from the bottom of hollow mobile jib 5; And, on traction fiber 7, be with sleeve pipe 8, and an end of sleeve pipe 8 being fixed on the top of hollow mobile jib 5, the other end of sleeve pipe 8 passes with the bottom of traction fiber 7 from hollow mobile jib 5.
As shown in Figure 1, the other end of conduit 6 preferably passes from the top of hollow mobile jib 5, and in the import 9 of conduit 6 check valve 10 is installed preferably, is convenient to inflation or topping up body in ring-shaped gasbag 1 like this, also is convenient to gas or liquid in the ring-shaped gasbag 1 are emitted.
Shown in attached Fig. 1 and 2, above technical characterictic has constituted this utility model embodiment 1.
Shown in accompanying drawing 1,2 and 3, embodiment 2 is with the difference of embodiment 1: the strut 4 of embodiment 2 comprises internal overarm support 11 and outer strut 12, one end of internal overarm support 11 is hinged on the top of hollow mobile jib 5, the other end of internal overarm support 11 is hinged with an end of outer strut 12, and the other end of outer strut 12 is hinged on the cross bar 3; And, internal overarm support 11 is rotated counterclockwise the interior stopping means 13 that surpasses 35 degree with the restricted internal overarm support 11 in hinged place of hollow mobile jib 5, restricted outer strut is rotated counterclockwise the outer stopping means 14 of spending above 45 and in the internal overarm support 11 and the hinged place of outer strut 12, make the central hollow part of the ring-shaped gasbag after the expansion relatively large by traction fiber 7 like this, thereby more help blood circulation, in embodiment 2, as shown in Figure 3, on traction fiber 7, can there be sleeve pipe.
In this utility model, can increase and decrease its inessential technical characterictic according to actual needs, as: the upper end of hollow mobile jib is that lower end that seal or the hollow mobile jib is that all seal at two ends that seal or hollow bar; The outside, bottom at the hollow mobile jib is equipped with holder 15, but 15 1 sleeve pipes of this holder play the endovascular blood of prevention and flow out from the outside of hollow mobile jib 5 bottoms; And the place that in use may leak blood to this utility model seals; Support pad 2 can adopt folding glass cloth to make; Can be connected to Pressure gauge at conduit on the outer end, like this so that control the journey that expand into of ring-shaped gasbag as required, and it is hemorrhage effectively to stop hepatic vein better.
This utility model simple and compact structure utilizes this liver second hepatic portal occlusion device can effectively stop the hemorrhage not occlude blood circulation again of hepatic vein, has reduced the influence to cardio-pulmonary function, thereby has helped the success of operation on liver.
