Abstract
The invention provides a pin abutting seat for a surgical staple. The pin abutting seat comprises a seat body, wherein a head portion of the seat body is connected with a cover of the pin abutting seat in the surgical staple, one end, opposite to the cover of the pin abutting seat, of the seat body is provided with a plurality of screw slots, each two screw slots forms one group, and the two screw slots in one group are symmetrical. The pin abutting seat is characterized in that each screw slot is in an isosceles trapezoid shape, short straight sides of the screw slots in each group are close, two side walls in the inclined side directions of the screw slots are inclined towards to bottoms in the slots along the straight side directions, and the side walls, from the inclined side direction to two straight side directions, of the bottoms of the screw slots are expanded to form arc surfaces. Forming surfaces of the screw slots are designed into specific arc shapes, so that the screw slots have a direction self-guidance property; during a percussion titanium screw forming process, the phenomenon that a B shape produced by irregular motion of screw clamps in the screw slots is not in the same plane is avoided, and good seaming effects of operations are achieved.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of needle stand that supports that is applied to surgery intestinal EEA surgical stapler.
Background technology
It is identical with stapler that kiss (seam) closes the operation principle of device, and staple from two rows of mutually staggered to percussion in tissue that insert is carried out two rows to tissue and intersected nail seam, and stitching tightly, prevents seepage; Because little blood vessel can pass through from the space of " B " shape staple, therefore do not affect the blood supply of suturing part and far-end thereof.All staples are that Titanium or tantalum are made, and compared with manual suture line, tissue reaction is little.
Follow closely wound is sewed up by supporting needle stand and realized stitching with titanium, but in prior art, nail groove on nail supporting base is all regular geometric shape, all generally rectangular, the width of this structure nail groove is greater than the diameter of titanium nail, and titanium nail can shake in the time of bending in nail groove, cannot realize the molding in same plane of titanium nail, cause intensity difference after the molding of titanium nail, has sewed up be organized in convalescent period there will be oozing of blood even wound ftracture.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of anastomat with supporting needle stand, nail groove shape has direction self-conductance position property, in percussion titanium nail forming process, avoid nail clip irregular movement in nail groove, and not phenomenon at grade of the B font producing.
For achieving the above object, technical scheme of the present invention is as follows:
A kind of anastomat is with supporting needle stand, comprise pedestal, the head of described pedestal is connected with the needle stand block that supports in described anastomat, the relatively described one end of supporting needle stand block of described pedestal is provided with several nail grooves, two of described nail grooves are one group, two nail grooves in each group are symmetrical arranged, described nail groove is isosceles trapezoid, the close setting of short straight flange of the nail groove in each group, two side in described nail groove hypotenuse direction tilts along straight flange direction to groove inner bottom part, and nail trench bottom forms cambered surface along the sidewall expansion of hypotenuse direction picture two straight flange directions.
Preferably, described cambered surface is made up of two sections of tangent circular arcs, and described circular arc is divided into circular arc one and circular arc two from the short straight flange of nail groove successively to the long straight flange of far-end.
Preferably, the radian of described circular arc one is less than the radian of described circular arc two.
Preferably, each is organized between two short straight flanges of described nail groove and is provided with circular arc chamfering, and three and two described circular arcs one of circular arc that described circular arc chamfering forms are tangent.
Preferably, it is trapezoidal that described pedestal is cylinder, and described nail groove is inside and outside two coil arrays around the rotating shaft of described pedestal to be arranged, and on Internal and external cycle every group nail groove cross-distribution.
Preferably, counterbore is inwardly offered in the relatively described one end of supporting needle stand block of described pedestal, and on end face, forms a ring face, and the spacing between nail groove and the internal diameter of described anchor ring on described inner ring is 0.3mm～1mm.
Pass through technique scheme, anastomat provided by the invention is with supporting needle stand, by design, the forming surface of nail groove is designed to specific arcuate shape, make to follow closely groove and there is direction self-conductance position property, in percussion titanium nail forming process, avoided nail clip irregular movement in nail groove, and not phenomenon at grade of the B font producing makes operation reach good sewing effect.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described.
As shown in Figure 1-2, a kind of anastomat is with supporting needle stand, comprise and be the trapezoidal pedestal of cylinder 11, pedestal 11 relatively supports one end of needle stand block and inwardly offers counterbore 12, and on end face, form a ring face 13, the head of pedestal 11 is connected with the needle stand block that supports in anastomat, one end that pedestal 11 supports needle stand block is relatively provided with several nail grooves 14, 14 two of grooves of nail are one group, nail groove 14 is inside and outside two coil arrays around the rotating shaft of pedestal 11 and arranges, and every group of nail groove 14 cross-distribution on Internal and external cycle, spacing between nail groove 14 on inner ring and the internal diameter of anchor ring 13 is 0.3mm～1mm.
Referring to Fig. 3 to 4, nail groove 14 is isosceles trapezoid, the close setting of short straight flange of the nail groove in each group, the two side in nail groove 14 hypotenuse directions tilts along straight flange direction to groove inner bottom part, and nail groove 14 bottoms form cambered surface along the sidewall expansion of hypotenuse direction picture two straight flange directions.Cambered surface is made up of two sections of tangent circular arcs, and circular arc is divided into circular arc 1 and circular arc 2 16 from the short straight flange of nail groove successively to the long straight flange of far-end, and the radian of circular arc 1 is less than the radian of circular arc 2 16.Between two short straight flanges of one group of nail groove 14, be provided with circular arc chamfering, circular arc 3 17 and two circular arcs 1 that circular arc chamfering forms are tangent.
