Description
Technical field
The present invention relates to medical instruments field, particularly relate to a kind of nail anvil for anastomosis staple stereo shaping and staple formation method.
Background technology
Utilize anastomat suture tissue to be common in various operation technique, doctor utilize linear anastomat or belt anastomat to pull the trigger in tissue staple that implantation two row intermeshes carries out double intersections nail seam to tissue, sew up tightly, prevent seepage; Because thin vessels 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; Due to staple marshalling, spacing is equal, sews up elasticity and is controlled by scale, avoids manual suture and crosses thin overstocked excessively loose with ligation tension, therefore ensure that highly organized healing.Hands intraoperative hemorrhage is more serious, therefore all kinds of doctor all takes much count of bleeding problems, analysis hemorrhage after utilizing the stitching of anastomat staple is found: if the shut height of staple too high and can not by nail circle contain in-house comparatively trunk and press off, incisxal edge place will be caused hemorrhage, and the shut height of staple is too low also can cause squeezing property bleeding due to trauma to tissue.Although staple height meets hemostasis requirement sometimes, but many times the end of cutting of some tissues still has local oozing phenomenon, think through large quantifier elimination, this is relevant with current staple arrangement mode, current staple aligning method is difficult to avoid cutting the hemorrhage of end, its staple still has hemostasis weakness place online, is mainly reflected in two places: the space 1, between two staples; 2, the space between " B " staple two contoured bands.
Summary of the invention
For above-mentioned deficiency of the prior art, main purpose of the present invention is to provide a kind of nail anvil and staple formation method of anastomosis staple stereo shaping, utilize this nail anvil that the identical connection of tissue can be made even, anastomosis staple is uniformly distributed in tissue, occur simultaneously in the local avoiding anastomosis staple, be organized in around titanium silk and evenly wrap up, the chance that anastomotic stoma is inflamed is less, and anastomotic stoma is more easily fullyed recover from an illness conjunction.
For achieving the above object, the technical solution used in the present invention is: a kind of nail anvil of anastomosis staple stereo shaping, comprise nail anvil body, described nail anvil body is provided with four nail forming tank and cutter gathering sill, the both sides of described cutter gathering sill are equipped with two nail forming tank, and the two nail forming tank being positioned at cutter gathering sill the same side are staggered; Every nail forming tank is provided with some staple formation slotted eyes, described each staple formation slotted eye is made up of two identical holes, the cross section in described two identical holes is sealene triangle, and the sealene triangle that the cross section in described hole is has one group of adjacent limit orthogonal.
Preferably, two holes of described composition staple formation slotted eye are respectively the first slotted eye, the second slotted eye, and a hypotenuse of the hypotenuse of sealene triangle that the cross section of described first slotted eye is and the sealene triangle that the cross section of described second slotted eye is on the same line.
Preferably, the length of described staple formation slotted eye is between 4.8mm-5.5mm.
Preferably, the bottom side length of the cross section of described first slotted eye and the second slotted eye sealene triangle that is is between 1.0mm-1.8mm.
The invention also discloses a kind of anastomosis staple stereoforming method, the method operating procedure is as follows: be placed in by anastomosis staple in the nail bin of anastomat, operation anastomat makes nail bin and nail anvil close, and the anastomosis staple in nail bin is pushed in nail anvil under the effect of the pushing slice of nail of anastomat, and molding in nail anvil.
The invention also discloses the anastomosis staple after a kind of nail anvil molding of above-mentioned anastomosis staple stereo shaping, described anastomosis staple is B shape structure, described anastomosis staple comprises an anastomosis staple mobile jib and is located at the semicircle syringe needle at anastomosis staple mobile jib two ends, the center that the two ends of described two halves circular syringe needle self-fitting nail mobile jib are risen to anastomosis staple mobile jib bends semicircular in shape, and the top of the circular syringe needle of described two halves lays respectively at the both sides of described anastomosis staple mobile jib.Preferably, a straight line is done on the top to this semicircle syringe needle from the junction of one of them semicircle syringe needle and described anastomosis staple mobile jib, and described straight line and described anastomosis staple mobile jib place straight line are an angle, and the number of degrees of described angle are between 0 °-90 °.Preferably, the number of degrees of described angle are between 10 °-45 °.Preferably, the wide of described anastomosis staple mobile jib is 1.0mm-2.0mm
Corresponding, the nail of nail anvil and nail bin is to the nail groove that should have solid forming.Anastomosis staple of the present invention all adopts Titanium silk to make.
Compared with prior art, the present invention adopts the method for anastomosis staple solid forming, the two ends of the anastomosis staple after molding form semi-enclosed semicircle, make the identical connection of anastomosis staple group, tissue evenly, this mode makes in anastomosis staple forming process, titanium silk is uniformly distributed between tissue, and the local common factor avoided because of titanium silk makes to organize easily generation inflammation point.Anastomosis staple of the present invention is in tissue after molding, and the titanium silk not common factor of solid forming itself, is separate, is organized in around titanium silk and evenly wraps up, and the chance that the anastomotic stoma of tissue is inflamed less, more easily fully recover from an illness conjunction by anastomotic stoma.
The stitching mouth of the tissue encapsulation body utilizing the anastomosis staple after stereo shaping of the present invention to sew up coincide than common evenly, anastomosis staple forms a space network between tissue, is easy to hemostasis and the confession of normal blood.The nail anvil of anastomosis staple stereo shaping of the present invention is applicable to circular staplers and line anastomat, " B " type anastomosis staple can adopt various arrangement mode, the parcel circle of two circles formed when being shaped with anastomosis staple decides the sewing effect of tissue, and the parcel circle of solid forming technology shape is more evenly distributed on tissue apposition band.
The invention has the beneficial effects as follows: after the nail anvil of anastomosis staple stereo shaping of the present invention can make staple formation, make the identical connection of tissue even, anastomosis staple is uniformly distributed in tissue, occur simultaneously in the local avoiding anastomosis staple, be organized in around titanium silk and evenly wrap up, the chance that anastomotic stoma is inflamed is less, and anastomotic stoma is more easily fullyed recover from an illness conjunction.
