Abstract
The utility model discloses a novel disposable anastomat, including the anastomat body, annular evenly spaced distribution has a plurality of grooves of sewing up on the anastomat body, and the notch both ends of sewing up the groove are the arc structure, and the notch protrusion in the anastomat body of sewing up the groove is on the surface of anastomat body. The notch of the suture groove of the utility model protrudes out of the surface of the anastomat body, and the protruded notch is favorable for slightly supporting the blood vessel to form a slight bulge, thereby being convenient for a surgeon to quickly identify the region needing crochet hook suture and being favorable for accurate suture of the blood vessel; the notch both ends of sewing up the groove are the arc structure, and when convex notch propped up blood vessel slightly, can fall to minimumly to the oppression of blood vessel intima with notch both ends camber department, and then will fall to minimumly to the harm of blood vessel intima.
Description
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to novel disposable anastomat.
Background
At present, when a doctor performs anastomosis operation on a disconnected blood vessel of a patient, forceps are generally used for clamping an outer membrane of the blood vessel to fix the blood vessel, a needle with a wire is inserted into the outer wall of one disconnected blood vessel, then the needle enters another disconnected blood vessel from the inner cavity of the one blood vessel, and the outer wall is inserted into the inner wall of the other blood vessel.
The utility model discloses a blood vessel anastomat of grant notice No. CN208551900U, including the branch pipe, be provided with the blood passageway in the branch pipe, the branch pipe includes the card income portion at both ends and middle connecting portion, connecting portion are provided with 12 sewing grooves of annular even interval distribution on the surface, wherein be provided with the air duct between two sewing grooves, the air duct communicates with the blood passageway in the branch pipe, be provided with the pneumatic valve on the air duct, the utility model discloses the well branch pipe is used for connecting between two cracked blood vessels, and card income portion is used for stretching into cracked blood vessel, and blood realizes circulating from the blood passageway, after branch pipe connection has done the blood vessel, adopts the crochet hook to sew up the blood vessel, and the branch pipe provides a power of supporting at first, and the crochet hook can cross the needle from sewing the inslot, and can not destroy other organs and blood vessel, has realized safe convenient quick, is very suitable for clinical use.
However, the above utility model still remains to be improved: 1. the structural design of the two ends of the opening of the suture groove has different influences on the damage of the intima of the blood vessel; 2. the notch of the suture groove is planoconvex relative to the surface of the anastomat body, which plays a great role in accurate suture of the blood vessel. The technical solutions and advantages of the two points to be improved are not disclosed in the above utility model patents.
SUMMERY OF THE UTILITY MODEL
To the deficiency that prior art exists, the utility model provides a novel disposable anastomat.
The utility model discloses a realize through following technical scheme: the utility model provides a novel disposable anastomat, includes the anastomat body, annular evenly spaced distribution has a plurality of sews up the groove on the anastomat body, the notch both ends that sew up the groove are the arc structure, the notch protrusion in that sews up the groove in the surface of anastomat body.
Compared with the prior art, the beneficial effects of the utility model are that: the notch of the suture groove of the utility model protrudes out of the surface of the anastomat body, and the protruded notch is favorable for slightly supporting the blood vessel to form a slight bulge, thereby being convenient for a surgeon to quickly identify the region needing crochet hook suture and being favorable for accurate suture of the blood vessel; the notch both ends of sewing up the groove are the arc structure, and when convex notch propped up blood vessel slightly, can fall to minimumly to the oppression of blood vessel intima with notch both ends camber department, and then will fall to minimumly to the harm of blood vessel intima.
Drawings
Fig. 1 is a schematic front view of the present invention;
fig. 2 is a side view of the present invention.
In the drawings: 1. a stapler body; 2. sewing the groove; 3. a notch.
Detailed Description
The novel disposable anastomat comprises an anastomat body 1, a plurality of suture grooves 2 are distributed on the anastomat body 1 at equal intervals in an annular mode, two ends of a notch 3 of each suture groove 2 are of arc-shaped structures, and the notch 3 of each suture groove 2 protrudes out of the surface of the anastomat body 1.
The notch of the suture groove of the utility model protrudes out of the surface of the anastomat body, and the protruded notch is favorable for slightly supporting the blood vessel to form a slight bulge, thereby being convenient for a surgeon to quickly identify the region needing crochet hook suture and being favorable for accurate suture of the blood vessel; the notch both ends of sewing up the groove are the arc structure, and when convex notch propped up blood vessel slightly, can fall to minimumly to the oppression of blood vessel intima with notch both ends camber department, and then will fall to minimumly to the harm of blood vessel intima.
In summary, the present invention is only a preferred embodiment, and is not intended to limit the scope of the present invention, and all equivalent changes and modifications of the shapes, structures, features and spirit described in the claims of the present invention should be included in the scope of the present invention.
