Detailed description of the invention
As shown in the figure: the operation elastic separating plier that can be used for Ureteral anastomosis, comprise shell 1, fixed handle 2, flexible handle 3, nail pressing handle 4, nail supporting base 5, nail bin 6, nail pressing plate 7, be separated pull bar 8, nail pressing pull bar 11 and pantograph linkage 9.
Described shell 1 comprises feeler lever housing 101 and handle housing 102 two parts, feeler lever housing 101 and handle housing 102 all have a cavity, and the cavity of feeler lever housing 101 and handle housing 102 is interconnected, described fixed handle 2 is connected with handle housing 102 one, flexible handle 3 and nail pressing handle 4 are all arranged on handle housing 102 by hinge, flexible handle 3 is arranged between fixed handle 2 and nail pressing handle 4, and flexible handle 3 is consistent with the direction of motion of nail pressing handle 4.Described fixed handle 2, flexible handle 3 and nail pressing handle 4 are equipped with anti-skidding convex stripe.Described flexible handle 3 is also provided with tight locking button, tight locking button is for locking the position of flexible handle 3, also socket is provided with in the part of handle housing 102, spigot is provided with connecting pin, this connecting pin can directly connect high-frequency electrical condenser, connecting pin also be separated pull bar 8 and connect, in operation, anastalsis can be realized by the high-frequency electrocoagulation of access.
Described separation pull bar 8 and nail pressing pull bar 11 are all located in the cavity of feeler lever housing 101, the one end and the flexible handle 3 that are separated pull bar 8 are hinged, the other end being separated pull bar 8 connects nail supporting base 5 and nail bin 6 by pantograph linkage 9, one end and the nail pressing handle 4 of nail pressing pull bar 11 are hinged, and the other end of nail pressing pull bar 11 is connected with nail pressing plate 7 by swingle 906.
Described separation pull bar 8 is fixed with two limited blocks 13, separation pull bar 8 between two limited blocks 13 is arranged with sleeve 14, and being provided with back-moving spring 10 away between the limited block 13 of feeler lever housing 101 and sleeve 14, described sleeve 14 is connected with nail pressing pull bar 11 by connecting rod 12.
Described pantograph linkage 9 stretches out plate 901 by two, shrinking connecting-rod I 902, shrinking connecting-rod II 903, steady pin 904, removable pin 905 and swingle 906 form, two stretch out plate 901 be set in parallel in feeler lever housing 101 away from handle housing 102 one end, the one end of stretching out plate 901 is fixedly connected with the inwall of feeler lever housing 101, the other end stretching out plate 901 stretches out feeler lever housing 101, two are stretched out between plate 901 and are equipped with steady pin 904, steady pin 904 is arranged on away from feeler lever housing 101 one end, shrinking connecting-rod I 902 and shrinking connecting-rod II 903 are by two the connecting rod compositions be hinged, the two ends of shrinking connecting-rod I 902 and shrinking connecting-rod II 903 respectively with steady pin 904 and removable pin 905 hinged, the connecting rod that shrinking connecting-rod I 902 is hinged with steady pin 904 is connected nail supporting base 5, the connecting rod that shrinking connecting-rod II 903 is hinged with steady pin 904 is fixedly connected with nail bin 6, swingle 906 is hinged on steady pin 904 by middle part, swingle 906 connects nail pressing plate 7 near nail bin 6 one end, the other end and the nail pressing pull bar 11 of swingle 906 are hinged.
When pulling flexible handle 3, move after being separated pull bar 8, pull shrinking connecting-rod I 902 and shrinking connecting-rod II 903, make shrinking connecting-rod I 902 be tending towards parallel with two connecting rods of shrinking connecting-rod II 903, thus the nail supporting base 5 be connected with connecting rod and nail bin 6 realize clamping, now, pull nail pressing handle 4, move after nail pressing pull bar 11, driven rotary bar 906 rotates, thus nail pressing plate 7 is moved towards nail bin 6 one end, the staple in nail bin 6 is got by final realization.
Nail bin 6 of the present invention can cooperate with the nail groove on known nail supporting base 5 anastomosis procedure.What the bottom surface, two ends (namely two nail lower limbs of staple enter the region of groove) of described nail supporting base 5 being followed closely groove was depression is spherical, whole nail groove top view is dumbbell shape, when suture needle is pulled the trigger in importing nail groove, because the bottom surface of following closely groove is spheroidal, therefore no matter the nail lower limb of staple falls into any region of the spheroidal bottom surface of nail groove, under the effect of the spheroidal bottom surface of nail groove, automatically can be adjusted to the center of nail groove bottom after nail lower limb is stressed, thus greatly can improve the probability of staple correct forming.
In operation process, doctor first take out from aseptic package bag be equipped with staple can suture operation elastic separating plier, elastic separating plier is put into the tissue needing to coincide, control the position clamping that ureter needs to sew up by flexible handle 3, stir tight locking button by locked for the position of flexible handle 3, then nail pressing handle 4 is pulled, so nail pressing plate 7 moves and promotes the staple injection in nail bin 6 further under the effect of nail pressing handle 4, staple enters in tissue to be anastomosed, and under the effect of nail supporting base 5, be closed into B font.Described nail supporting base 5 and nail bin 6 can be annular, also can be linear.
