When the closed position, one row of most inner side supports staple line 24a (i.e. from a nearest row for resist-nailed seat slot 22) and nail bin groupware 3
The distance of top end face 312 is H1, it is H at a distance from the top end face 312 of nail bin groupware 3 that an intermediate row, which supports staple line 24b,2, outermost one
It is H at a distance from the top end face 312 of nail bin groupware 3 that row, which supports at staple line 24c (i.e. from a farthest row for resist-nailed seat slot 22),3,
Middle H3> H2> H1.In this way, the degree that the destination organization at ejector pin slot 34 is squeezed is bigger, the mesh at ejector pin slot 34
The degree that mark tissue is squeezed is smaller, facilitates tissue fluid and is discharged outward.
As shown in figure 14, the top end face 312 when resist-nailed seat 2 is located at the closed position, from 22 farthest of resist-nailed seat slot
It is equipped with groove 39, because the outside of the top end face 312 of nail bin groupware 3 is arranged fluted 39,312 distance of top end face at groove 39
The vertical range of resist-nailed seat 2 is larger, (i.e. by the top end face 312 at the outermost anastomosis staple 35 of the top end face 312 of nail bin groupware 3
Farthest from resist-nailed seat slot 22) at a distance from resist-nailed seat 2 it is denoted as H3, by 312 rest part of top end face of nail bin groupware 3 with support
The distance of nail seat 2 is denoted as H1, wherein H3> H1, in this way, the compressed degree of destination organization close to resist-nailed seat slot 22 is big, help
It is discharged outward in tissue fluid.For stairstepping, top and bottom be cambered surface, top and bottom are inclined-plane or top and bottom are ladder
The combined molding space of shape, cambered surface and inclined-plane, the height close to ejector pin slot 34 and the molding space of resist-nailed seat slot 22 is small, tissue
The degree being squeezed is big, thus has more tissue fluid to need to be discharged, and the molding far from ejector pin slot 34 and resist-nailed seat slot 22 is empty
Between height it is big, organize the degree being squeezed small, there are less tissue fluid needs to be discharged, close to ejector pin slot 34 and support as a result,
The pressure that squeeze force in the molding space of nail seat slot 22 is larger, tissue fluid is promoted to be discharged is also larger, constitutes moving tissue liquid
Upstream, squeeze force in the molding space far from ejector pin slot 34 and resist-nailed seat slot 22 is smaller, the pressure that promotes tissue fluid to be discharged
It is smaller, downstream is constituted, the squeeze force interaction in the molding space of different height forms one from ejector pin slot 34 and resist-nailed seat
Slot 22 is directed toward power far from 22 direction of ejector pin slot 34 and resist-nailed seat slot, promoting tissue fluid to discharge, to form fluid ladder
Degree, promotes tissue fluid to be discharged from upstream to downstream.Relative to the molding space of sustained height, by lesser squeeze force, have compared with
The region inner tissue of few tissue fluid discharge demand is to by biggish squeeze force, the region for having more tissue fluid that demand is discharged
The acting in opposition (i.e. obstruction tissue fluid discharge) that inner tissue is formed can become smaller, and facilitate close to ejector pin slot 34 and resist-nailed seat slot 22
The tissue fluid of tissue in molding space is discharged.Meanwhile groove 39 constitutes the passing away of tissue fluid, improves tissue fluid
The velocity of discharge；Due to the setting of groove 39, the discharge of tissue fluid becomes unobstructed, further enhances the effect of fluid gradient.Into
One step, as shown in Figure 2 c, nail cavity 32 forms nail mouth through top end face 312, and the outside of top end face 312 is equipped with outward opening
Groove 39.Groove 39 is arranged along the outside spacers of top end face 312, is uniformly distributed, and groove 39 is the "u"-shaped groove of outward opening, recessed
The " u "-shaped opening of slot 39 is extended to intersect with the lateral surface of staple cartridge body 31, is conducive to the effect that groove 39 plays fluid channel,
Accelerate the discharge of tissue fluid.Preferably, the bottom surface of groove 39 is inclined-plane or integral inclined curved surface, the inclination side on inclined-plane and curved surface
To be it is low inside and high outside, be more conducive to the discharge of tissue fluid.Since liquid is difficult to be compressed, the tissue rich in tissue fluid be also difficult to by
Squeezing.Therefore, the tissue fluid at destination organization is comparatively fast discharged, can effectively shorten compression tissue to specified altitude assignment time, in this way,
Time needed for natural time from closure end effector 100 to percussion surgery cuts hair stapler can meet squeezing, no
It needs that squeezing is specially waited to complete, meets the operation continuity of doctor, shorten operating time, avoid tissue and squeeze not enough
Situation, and then guarantee the molding effect of anastomosis staple.Nail bin groupware and its surgical instruments according to the present invention, can to organize into
Size and the identical anastomosis staple of shape are formed into the staple line for having different nails high while row cutting and are applied to tissue.It is closest to cut
The forming height of the nail of secant is smaller than the forming height of the nail farthest apart from cutting line, closest to cutting line at nail for mentioning
For hemostatic barrier, and the outside with larger forming height at nail provide tissue from the hemostasis section transitions of tight compression to
The clamping effect of the adjacent part of not close compression.Pass through groove 39 spaced on the top end face of nail bin groupware, groove
39 constitute the accommodation space and passing away of tissue fluid, improve the velocity of discharge of tissue fluid；Due to the setting of groove 39, group
The discharge for knitting liquid becomes unobstructed, further enhances the effect of fluid gradient, accelerates the moving tissue liquid at destination organization, effectively
Shorten compression tissue to the time of specified altitude assignment, does not need that squeezing is specially waited to complete, meet the operation continuity of doctor, shorten
Operating time avoids tissue and squeezes inadequate situation, and then guarantees the molding effect of anastomosis staple.
