The specific embodiment

Below in conjunction with the embodiment accompanying drawing, the invention will be further described.

Referring to accompanying drawing, anastomat of circular closing organ for operation provided by the present invention comprises alligator clamp, two intermediate plates 5 of alligator clamp all are the semicircle tubulose, two intermediate plates 5 are under the effect of spring 10 power, tightly concentric cylindrical stent 7 is with it encircled, promptly the inner surface of intermediate plate 5 contacts with the intimate of the set convex shoulder 8 in support 7 middle parts.Why support 7 is designed to two ends is thin neck shape, to be spacing in order when performing the operation the organ broken ends of fractured bone being carried out, and to grip.In the ordinary course of things, the radius income value that the radius of the convex shoulder 8 of support 7 deducts narrow neck part should be slightly less than the wall thickness of organ tube wall, and is reliable to guarantee clamping.The organ broken ends of fractured bone can not carry out annular knurl at the inner surface both ends of alligator clamp intermediate plate 5 from slippage on the anastomat support when further guaranteeing to perform the operation, and annular knurl 13 can be a straight burr, also can be netted stricture of vagina etc.In addition, also can carry out annular knurl by the thin cervical region of while at support 7 two ends.

Needle gage is equal fully when guaranteeing by means of the annular enclosed organ broken ends of fractured bone of the invention process suture operation, be evenly equipped with the slot-shaped off-line groove 9 more than three along the axial border of support 7, the gap width of groove should be decided on the diameter of sewing needle, generally should be less than the sewing needle diameter, can be between 0.001-2.000mm, the concrete number of off-line groove 9 should be looked the caliber size that is sewn organ and be determined, generally selects between 3-100.The bottom land of off-line groove 9 is guide pin slots 12 of circular arc, and diameter and radian that the cross-sectional diameter of guide pin slot 12 should be slightly larger than sewing needle are identical with sewing needle, so that the sewing needle of band wire can successfully pass in guide pin slot 12.
