The specific embodiment
In conjunction with the accompanying drawings, this utility model has disclosed a kind of single-head pouch stitching instrument, and is same as the prior art, comprises the last holder 1 and the following holder 2 of hinged setting, and described rear end of going up holder 1 and following holder 2 is a grip handle 3.Unlike the prior art be, the front end of last holder 1 is provided with nail bin groupware, described nail bin groupware comprises nail bin 4 and places pushing slice of nail 5, nail 6 and purse wire 7 in the nail bin 4 that the described front end correspondence of holder 2 down is provided with nail forming tank 8.
The reason of She Zhiing is when doing the operation of male's pelvic cavity low rectal like this, because these distinctive characteristics of performing the operation, the zone of operation is too little, the automatic purse-string suture device of prior art cannot be put into operative region, and this utility model is owing to have only the front end of last holder 1 to be provided with nail bin groupware, the front end of following holder 2 can manufacture and design less relatively, so just solved above-mentioned problem, just can continue to finish to have performed the operation.
Further, because purse-string suture device generally all is to do purse string suture for the tubular tissue, and the front end of holder 2 is provided with nail forming tank 8 under this utility model, therefore when finishing purse string suture, pushing slice of nail 5 can penetrate nail 6 in the two layers of walls of tubular tissue, therefore can unite by a seam the end of tubular tissue.But because after purse string suture finishes, also needing to use the tubular type anastomat that two sections tubular tissues are coincide arrives together, and need pin anvil shaft or anvil pull rod are placed in the pocket that tied just now before the operation like this, the tissue that therefore ties pocket must have the space that allows pin anvil shaft or anvil pull rod to pass.Solution of the present utility model is to be and not to be equally spaced being arranged on pushing slice of nail 5 in the nail bin 4 and nail 6.Specifically, be arranged on distance between the pushing slice of nail 5 that the pushing slice of nail 5 of nail bin 4 outermost end is adjacent less than the distance that is arranged between the pushing slice of nail 5 that nail bin 4 intermediary pushing slice of nail 5 are adjacent, adopt the mode of " outer close interior rare ", be that the interlude of finishing the tissue of purse string suture has certain elasticity, thereby pin anvil shaft or anvil pull rod can be passed.
In this preferred embodiment, the distance that is arranged between the pushing slice of nail 5 that the pushing slice of nail 5 at nail bin 4 two ends is adjacent is roughly the same, and is far smaller than the distance that is arranged between nail bin 4 the most intermediary two pushing slice of nail 5.Certainly, the so-called pushing slice of nail 5 of this utility model is and is not equally spaced, and also comprises from the distance between two adjacent pushing slice of nail 5 of nail bin 4 outermost end, and is increasing to the distance between middle adjacent two pushing slice of nail 5 of nail bin 4, is the trend that increases progressively and arranges.
In this utility model, be provided with a gag lever post 9 between last holder 1 and the following holder 2, be used for the location of holder and following holder.
Introduce use of the present utility model below:
This utility model is encased in the holder 1 earlier with pushing slice of nail 5 and the nail 6 of packing in the nail bin 4, and with nail bin 4 before use.Then purse wire 7 is put in the nail bin 4.During use, the last holder 1 that installs down nail bin 4 is put into below the tissue of field of operation, will be descended holder 2 to put into the tissue top of field of operation then, holder is relative about making, and forms the suture zone.Firmly clamp the grip handle 3 of holder 1,2 up and down then, nail bin 4 is arrived to down on the holder 2, pushing slice of nail 5 will follow closely 6 and pull the trigger this moment, and because the effect of nail forming tank 8 is fixed to tissue, purse wire 7 is enclosed between nail and the tissue simultaneously, take pouching device then away, tighten up purse wire, finish the pocket seam and prick.
This utility model still has multiple concrete embodiment.Because last lower casing the 1, the 2nd, two similar shells also can be replaced and are arranged on down on the holder 2 so be installed in nail bin 4 on the holder 1 in this utility model, go up accordingly to be provided with on the holder 1 and follow closely forming tank 8.The position of only changing nail bin 4 and nail forming tank 8 belongs to the equivalent of technical solutions of the utility model, and all employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the claimed scope of this utility model.
