The specific embodiment

As shown in the figure: can be used for the operation elastic separating plier of Ureteral anastomosis, comprise shell 1, fixed handle 2, flexible handle 3, press and follow closely handle 4, nail supporting base 5, nail bin 6, pressure nail-plate 7, separation pull bar 8, pressure nail 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 pressure nail handle 4 all are arranged on the handle housing 102 by bearing pin is hinged, flexible handle 3 is arranged on fixed handle 2 and presses between the nail handle 4, and flexible handle 3 is consistent with the direction of motion of pressing nail handle 4.Be equipped with anti-skidding convex stripe on described fixed handle 2, flexible handle 3 and the pressure nail handle 4.Also be provided with tight locking button on the described flexible handle 3, tight locking button is used for the position of locking flexible handle 3, part at handle housing 102 also is provided with socket, spigot is equipped with connecting pin, this connecting pin can directly connect the high-frequency electrical condenser, connecting pin also with separate pull bar 8 and be connected, can in operation, realize anastalsis by the high-frequency electrocoagulation by access.

Described separation pull bar 8 and pressure nail pull bar 11 all are located in the cavity of feeler lever housing 101, the end and the flexible handle 3 that separate pull bar 8 are hinged, the other end that separates pull bar 8 connects nail supporting base 5 and nail bin 6 by pantograph linkage 9, press an end of nail pull bar 11 hinged with pressure nail handle 4, press the other end of nail pull bar 11 to be connected with pressure nail-plate 7 by swingle 906.

Be fixed with two limited blocks 13 on the described separation pull bar 8, separation pull bar 8 between two limited blocks 13 is arranged with sleeve 14, and be provided with back-moving spring 10 between away from the limited block 13 of feeler lever housing 101 and sleeve 14, described sleeve 14 is followed closely pull bar 11 and is connected with pressing by connecting rod 12.

Described pantograph linkage 9 is stretched 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 1 ends, an end that stretches out plate 901 is fixedly connected with the inwall of feeler lever housing 101, the other end that stretches out plate 901 stretches out feeler lever housing 101, two are stretched out and are equipped with steady pin 904 between the plate 901, steady pin 904 is arranged on away from feeler lever housing 101 1 ends, shrinking connecting-rod I 902 and shrinking connecting-rod II 903 form by two connecting rods that are hinged, the two ends of shrinking connecting-rod I 902 and shrinking connecting-rod II 903 are hinged with steady pin 904 and removable pin 905 respectively, be connected nail supporting base 5 on the hinged connecting rod of shrinking connecting-rod I 902 and steady pin 904, be fixedly connected with nail bin 6 on the hinged connecting rod of shrinking connecting-rod II 903 and steady pin 904, swingle 906 is hinged on the steady pin 904 by the middle part, swingle 906 connects near nail bin 6 one ends presses nail-plate 7, and the other end of swingle 906 is hinged with pressure nail pull bar 11.

When pulling flexible handle 3, move after separating pull bar 8, pulling shrinking connecting-rod I 902 and shrinking connecting-rod II 903 make two connecting rods of shrinking connecting-rod I 902 and shrinking connecting-rod II 903 be tending towards parallel, thereby the nail supporting base 5 that is connected with connecting rod and nail bin 6 are realized clamping, at this moment, pull and press nail handle 4, move behind the pressure nail pull bar 11, driven rotary bar 906 rotates, press nail-plate 7 to move towards nail bin 6 one ends thereby make, the final realization got the staple in the nail bin 6.

Nail bin 6 of the present invention can cooperate with the nail groove on the known nail supporting base 5 and finish the operation that coincide.The bottom surface, two ends of nail groove on the described nail supporting base 5 (following closely the zone that lower limbs enter groove for two that are staple) is the sphere of depression, whole nail groove is overlooked to observe and is dumbbell shape, when suture needle is pulled the trigger in the importing nail groove, because the bottom surface of nail groove is spheroidal, therefore no matter the nail lower limb of staple falls into any zone of the spheroidal bottom surface of nail groove, under the effect of the spheroidal bottom surface of following closely groove, can automatically be adjusted to the center of nail groove bottom after the nail lower limb is stressed, thereby can greatly improve the probability of staple correct forming.

In the operation process, but the doctor at first takes out the suture operation elastic separating plier that is equipped with staple from aseptic package bag, elastic separating plier is put into the tissue that need to coincide, the position that control flexible handle 3 need to be sewed up ureter clamps, it is locked with the position of flexible handle 3 to stir tight locking button, then pull and press nail handle 4, so press nail-plate 7 staple that migration also further promotes in the nail bin 6 under the effect of pressing nail handle 4 to penetrate, staple enters in the tissue to be coincide, and is closed into the B font under the effect of nail supporting base 5.Described nail supporting base 5 and nail bin 6 can be annular, also can be linear.
