Description
Technical field
This utility model relates to medical apparatus and instruments, especially relates to a kind of artificial blood vessel's bridge joint anastomat.
Background technology
Blood vessel embolism is current common disease, and caused by a variety of causes, it, on the impact of patient comparatively large (such as Bgudd-Chiari Syndrome etc.), needs operative treatment usually.Current therapeutic method of surgery has: 1, radiography placing rack, although this kind of mode wound is less, the blocking rate again after a year is higher; 2, open breast, abdomen carries out artificial blood vessel's bridge joint art.This kind of operation plan needs artificial blood vessel to be bridged to postcava and superior vena cava, weak point is that wound is longer, vascular anastomosis working place is very limited, substantially prolongs operating time, add operation risk and patient suffering, too increase the difficulty of operative doctor simultaneously.In addition, the manual blood vessel coincide easily forms oozing of blood, may need surgical hemostasis again, but due to the rough easy formation thrombosis in junction of native blood vessel and artificial blood vessel, thus cause operative failure.How in limited operation technique space, blood vessel bridge graft can be carried out fast, and to reach patient's physiology blood vessel and artificial blood vessel junction is smooth, the tight not easily oozing of blood in vascular anastomosis place is current problem in urgent need to solve.
Summary of the invention
This utility model provides a kind of artificial blood vessel's bridge joint anastomat, and object is to solve rough, the easy oozing of blood in blood vessel junction when carrying out blood vessel bridge graft operation at present, operating time length, the problem had a big risk.
For achieving the above object, this utility model can take following technical proposals:
Artificial blood vessel's bridge joint anastomat described in the utility model, comprises shell, described shell arranges handle, in described shell, be provided with the axis of guide vertically, and case head connects nail storehouse sleeve, and shell afterbody arranges adjusting knob; Arrange pushing slice of nail in described nail storehouse sleeve, be set with the endless knife of cylindrical structure between nail storehouse sleeve and the described axis of guide, described pushing slice of nail is connected with described handle by firing device with the endless knife of cylindrical structure; Described axis of guide one end connects described adjusting knob, the other end carries out detachable connection with nail supporting base, the base of described nail supporting base is arranged respectively the anastomosis staple matched with the endless knife of pushing slice of nail and cylindrical structure and be out of shape hole and to cutter ring, the described axis of guide is straight-bar, described nail storehouse sleeve is opening and closing type structure, is articulated structure between the central shaft of described nail supporting base and base.
Described nail storehouse sleeve is for columniform sleeve after the clamping that forms of two parts, or bottom-hinged and the cylindrical sleeve can opened along sidewall.
The described anchor ring supporting cutter ring offers the lower edge of a knife that annular groove is formed.
Between described handle and shell, bumper bar is set.
Described shell arranges display window.
The utility model has the advantage of that structure is simple, easy to operate, during use, corrective surgery otch is less, doctor can be helped to complete operation easily in less working place, greatly reduce the time of operation technique; Adopt anastomosis staple to connect the mode of physiology blood vessel and artificial blood vessel, blood vessel junction is closed tight, there will not be the phenomenon of the postoperative oozing of blood in anastomotic stoma place, reduces the risk of again performing the operation.

Detailed description of the invention
As shown in figs. 1-7, artificial blood vessel's bridge joint anastomat described in the utility model, comprises shell 1, it is arranged handle 2, is provided with the axis of guide 3 of direct rod shape in shell 1 vertically, and shell 1 head connects can the nail storehouse sleeve 4 of folding, and afterbody arranges adjusting knob 5; Arrange pushing slice of nail 6 in nail storehouse sleeve 4, be set with the endless knife 7 of cylindrical structure between nail storehouse sleeve 4 and the axis of guide 3, pushing slice of nail 6 is connected with handle 2 by firing device with the endless knife 7 of cylindrical structure; The axis of guide 3 one end connects adjusting knob 5, the other end carries out detachable connection with nail supporting base 8, the base of nail supporting base 8 is arranged respectively the anastomosis staple matched with the endless knife 7 of pushing slice of nail 6 and cylindrical structure and be out of shape hole 9 and to cutter ring 10, it is articulated structure between the central shaft of nail supporting base 8 and base, can folded bent 90 °, when carrying out anastomosis procedure as shown in Figure 2, folding 90 ° time as shown in Figure 3.
Above-mentioned can the nail storehouse sleeve 4, Ke Yiwei of folding: that two parts are formed, be columniform sleeve after clamping, see Fig. 4, it becomes the two parts be separated completely after opening, see Fig. 5; Or be bottom-hinged and the cylindrical sleeve can opened along sidewall, time closed as shown in Figure 6, when opening as shown in Figure 7.Nail storehouse sleeve 4 is opened the endless knife 7 of rear visible cylindrical structure, during use, need the two ends of Len req on the cylindrical external surface cover of endless knife 7 to have the artificial blood vessel of flanging.
As shown in Figure 2,3, on the anchor ring of cutter ring 10 setting, offer the lower edge of a knife 11 that annular groove is formed.
As shown in Figure 1, bumper bar 12 is set between handle 2 and shell 1, the maloperation that firing handle 2 unintentionally makes anastomosis staple mistake eject can be prevented.Shell 1 is arranged display window 13, the regulating degree according to adjusting knob 5 shows the gap length between nail supporting base 8 and nail storehouse sleeve 4.
During use, open nail storehouse sleeve 4, be enclosed within the cylinder outer surface of endless knife 7 by the artificial blood vessel being slightly longer than endless knife 7 drum length, then close nail storehouse sleeve 4, and artificial blood vessel is grown part outwards turnup formation flanging, flanging should coated pushing slice of nail 6.In the bridge joint place perforate of physiology blood vessel, folding nail supporting base 8, as shown in Figure 3, the tapping of extruding physiology blood vessel, puts into physiology Ink vessel transfusing by the base of nail supporting base 8, then inflection nail supporting base 8, as shown in Figure 2.After being connected with the axis of guide 3 by nail supporting base 8 by jump ring sleeve pipe, rotation of adjustment knob 5, observes the gap between nail supporting base 8 and nail storehouse sleeve 4 by display window 13.When arriving correct position, push bumper bar 12 aside, pressing handle 2, firing device makes the endless knife 7 of cylindrical structure and pushing slice of nail 6 push ahead, and while anastomosis staple connects artificial blood vessel and physiology blood vessel, endless knife 7 falls into the lower edge of a knife 11 pairs of physiology blood vessels and cuts.Open nail storehouse sleeve 4, then reversely rotate adjusting knob 5, the axis of guide 3 extends, and folding nail supporting base 8, as shown in Figure 3, is pulled outwardly handle 2, is taken out by nail supporting base 8 from physiology blood vessel and artificial blood vessel again.Afterwards, carry out bridge joint according to aforesaid operations at other bridge nodes of physiology blood vessel, and use other operating theater instruments to connect the artificial blood vessel after bridge joint.
