The specific embodiment
The present invention has disclosed a kind of Wedge-shaped cutting and binding apparatus, as shown in Figure 1, comprise nail bin 1, ejector pin bar 2 and nail anvil 3, and first holder 41 that is hinged and second holder 42, described ejector pin bar 2 is fixed on the front end of first holder 41, described nail anvil 3 is fixed on the front end of second holder 42, and the rear end of described first holder 41 and second holder 42 is holder handle 43.The same with prior art, described nail bin 1 and nail anvil 3 are oppositely arranged the suture zone that forms apparatus, need the tissue of seaming and cutting to be placed between the two.
In the present invention, to shown in Figure 3, the outline unanimity of described nail bin 1, ejector pin bar 2, nail anvil 3 all is the wedge shape setting in conjunction with Fig. 1.Described nail bin 1 is provided with nail bin hole 11 and cutter groove 12 that many row's wedge shapes are arranged with respect to the surface 14 of nail anvil 3.Be three row's nail bin holes 11 in this preferred embodiment, in order to obtain better sewing effect, two adjacent rows are that dislocation is arranged, and this is consistent with prior art, does not repeat them here, and described cutter groove 12 is arranged on wherein between two row's nail bin holes 11.Be provided with nail forming tank 31 and a cutter anvil 32 that three row's wedge shapes are arranged on the surface 34 of described nail anvil 3 with respect to nail bin 1 accordingly, same, described cutter anvil 32 is arranged on wherein between two row's nail forming tank 31.
Be fixed with one group of pushing slice of nail 21 and cutter 22 on the surface of the ejector pin bar 2 of described wedge shape.Described one group of pushing slice of nail 21 is similarly and is three row's wedge shape settings, and cutter 22 are arranged on wherein between two rows.Pushing slice of nail 21, nail bin hole 11, nail forming tank 31 threes' position is corresponding.Described pushing slice of nail 21 extend in the nail bin hole 11 of nail bin 1 movably, and cutter 22 extend in the cutter groove 12 of nail bin 1 movably, and the front end of described nail bin hole 11 inherent pushing slice of nail 21 also is provided with nail (prior art, not shown).Because pushing slice of nail 21 and cutter 22 all extend into nail bin inside, so another embodiment of the present invention is that pushing slice of nail 21 and cutter 22 directly are encased in the nail bin when assembling, and is not fixed on the ejector pin bar 2.
Nail bin hole 11 integral body of described nail bin 1 are wedge shape arranges, and cutter groove 12 is the wedge shape setting; Nail forming tank 31 integral body of correspondingly described nail anvil 3 are wedge shape arranges, and cutter anvil 32 is the wedge shape setting.Described one group of pushing slice of nail 21 is wedge shape and is arranged on the described ejector pin bar 2, and cutter 22 are wedge shape and are fixed on the described ejector pin bar 2.
Be fixedly connected with spring 24 between described nail bin 1 and the ejector pin bar 2.One end of spring is fixed on the nail bin 1, and the other end is fixed on the ejector pin bar 2.The surface of described ejector pin bar 2 is provided with two alignment pins 23, is separately positioned on the two ends that ejector pin bar 2 regards to the wedge-shaped surface of nail anvil 2.The surperficial corresponding position of described nail bin 1, nail anvil 3 is provided with two through holes 13 and two locating holes 33, and described spring 24 is socketed in the periphery of alignment pin 23.This alignment pin 23 can pass through hole 13, and extend in the locating hole 33, aims at nail bin 1 and nail anvil 3 when being used to operate.
As can be seen from Figure, two alignment pins 23 probably are 30 degree to the angle between the line of swivel pin, and promptly the size of angle has determined the size of the wedge shape main body of nail bin 1, ejector pin bar 2, nail anvil 3.But, this angle can be become big in order to cut and sew up wider tissue.Because technology of the present invention can manufacture nail bin 1, ejector pin bar 2, the nail anvil 3 of any size, therefore only change the technical scheme of above-mentioned corner dimension still within protection scope of the present invention.
The once assembling and the operating process of this preferred embodiment are simply described below.
Specifically as shown in Figure 2, first holder 41 and second holder, 42 usefulness pins are connected into scissor articulated manner, cutter 22 are fixedly installed on the ejector pin bar 2, to bind then into nail bin 1, with pushing slice of nail 21 nail bin 1 of also packing into, at last nail bin 1 is set on the alignment pin 23 on the ejector pin bar 2, makes cutter 22 be positioned at the wedge shape cutter groove 12 of nail bin 1.Described nail bin 1 and nail anvil 3 are oppositely arranged the suture zone that forms apparatus.
During operation, tissue is placed between nail bin 1 and the nail anvil 3 the handle holder 43 of firmly holding with a firm grip then, at this moment, nail bin 1 interacts with nail anvil 3, and nail bin 1 is with respect to nail anvil 3 back motion mutually, pull the trigger out thereby pushing slice of nail 21 will be followed closely, and under the cooperation of nail anvil 3, be shaped; Simultaneously, cutter 22 are released in wedge shape cutter groove, under the cooperation of the cutter anvil 32 of nail anvil 3 excess tissue are excised.
Because nail bin, nail anvil, nail bin hole all are into the wedge shape setting of roughly the same curvature, therefore, it is very good to use the tumor effect that this apparatus excision is positioned at organization edge, the cancerous issue at pulmonary edge for example, only need once can cutting and stitching to be shaped with this apparatus, and do not need as prior art cutting and stitching twice, avoided the generation of operation sequela, surgical effect is very good.
Be the wedge shape setting owing to cutter 22 in this example, so this Metal Cutting cutter 22 is necessary to adopt the rubber-like material to make.
The present invention still has multiple concrete embodiment, for example changes row's number in nail bin hole, and perhaps being arranged to ejector pin bar 2, nail anvil 3 with holder is dismountable the connection.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, all drop within the scope of protection of present invention.
