The concrete operations explanation:
Demonstration one:
At first stitch a draught line (also can be, each stitches two pins), and keep two pins on the draught line at the point of bisection place in each horizontal cotton-padded mattress formula of trunk broken ends of fractured bone trisection point.Guiding is plugged into the artificial blood vessel stapling apparatus.Under the guiding of guiding plug, a side of artificial blood vessel stapling apparatus is gone in the trunk, draught line is sewn on the seam ring of stapling apparatus.In the vascular anastomosis device, withdraw from the guiding plug.Suture with the band single needle falls into place's ligation trunk on seam ring side, and this binding is sewn on the ring.The elasticated net of cutting appropriate length holds the trunk on the artificial blood vessel stapling apparatus, sews up the tension elasticated net from the outside at two broken ends of fractured bone, and the suture sutured is being stitched on the ring.Opposite side can be inserted artificial blood vessel or human vas under the guiding that guiding is not filled in, coincide according to aforementioned aspect.
Shown in Figure 15 (operating procedure one): will be with blood vessel wall 19 broken ends of fractured bone trisections of soft tissue 20, dispose suture silk 22 at trisection point respectively, and this suture seam 22 is combined in the respective point of suture ring 8, a side of aorta anastomosis device is gone in the lumen of vessels 19, respectively the silk thread sewed up of ligation.Figure 15 is the axial arrangement cutaway view of aforesaid operations after finishing.
Shown in Figure 16 (operating procedure two): the blood vessel wall (19) of being coincide in the groove 11 places ligation of aorta anastomosis device with silk thread 23.Figure 16 is the axial arrangement cutaway view of aforesaid operations after finishing.
Shown in Figure 17 (operating procedure three): the cuff-shaped elastic net 13 of operation one side of coincideing launches, and is attached on the identical blood vessel wall 18.Figure 17 is the axial arrangement cutaway view of aforesaid operations after finishing.If the cuff-shaped elastic net appropriateness makes the Soft Roll of blood vessel wall and aorta anastomosis device be close to by 4, can vertically tighten up the stitching elasticated net with silk thread.Cuff-shaped elastic net also can make polyester flake into and achieve the above object.
Shown in Figure 18 (operating procedure four): with aorta anastomosis device finish after the operation of both sides vascular anastomosiss the axial arrangement cutaway view.
Demonstration two:
During end to end anastomosis between pedestrian's hemopoietic pipe and the artificial blood vessel, adopt III type artificial blood vessel stapling apparatus.At first with the suture ring trisection of the artificial blood vessel broken ends of fractured bone and III type artificial blood vessel stapling apparatus, sew up a side artificial blood vessel with three rhizoid line ecto-entads respectively, pass the garland shape seaming loop of artificial blood vessel's stapling apparatus then, stitched the opposite side artificial blood vessel more from inside to outside.Three rhizoid toe-ins are pricked.Second step, respectively with two rhizoid lines at the fixing artificial blood vessel of grooves on two sides ligation.The 3rd step held artificial blood vessel and artificial blood vessel's stapling apparatus with elasticated net or terylene bar, and blood vessel and stapling apparatus are close to.
Demonstration three:
Expose broken ends of fractured bone shorter one for human vas, can adopt V-type artificial blood vessel stapling apparatus.At first with the suture ring trisection of the human vas broken ends of fractured bone and V-type artificial blood vessel stapling apparatus, respectively with three rhizoid sutured human vas and artificial blood vessel's stapling apparatus.Cut off then and protect the slow-witted silk thread that support dwindles that shrinks, the contraction support is opened again with human vas and is close to.At last with silk thread at suture ring left groove place's ligation fixing human blood vessel.
Demonstration four:
During the operation of row trunk, adopt VII type artificial blood vessel stapling apparatus.When performing the operation, VII type artificial blood vessel's stapling apparatus and human vas are coincide in the first phase; According to the size of human vas, decision keeps the number of soft washer.When performing the operation, folding burying in the artificial blood vessel of support one side pulled out, make it the exhibition of stretching in the second phase.This artificial blood pipe is again with vascular anastomosis at a distance.
Elasticated net can be connected as a single entity with suture ring, also can not link to each other with the outer rim of suture ring, is rectangle, hold blood vessel after, tighten up fixedly elasticated net in the suture ligature mode.Elasticated net impacts the tension force of binding place that produces with the minimizing blood flow, and blood vessel and stapling apparatus is close in order to hold blood vessel.
This purposes of seven types is described respectively:
I type, II type are mainly used in IV type aorta anastomosis device and are connected human vas and human vas, and the one side also can link to each other with artificial blood vessel earlier, and opposite side links to each other with human vas.。
III type aorta anastomosis device is used for the connection between artificial blood vessel.
V-type, VI aorta anastomosis device are used to connect human vas, and wherein: V-type is specially adapted to ends of vessels and is difficult to the resurrectionist.
VII type aorta anastomosis device is used for the trunk operation of trunk.
