Description

Circular anastomosis ring

Technical Field

The invention relates to the technical field of medical instruments, in particular to a circular anastomosis ring.

Background

The anastomat is a device used in medicine to replace manual suturing, and the operation principle of the anastomat is the same as that of a stapler, namely two rows of mutually staggered staples are implanted into tissues in a percussion mode to carry out double-row cross stapling on the tissues, suturing is tight, and leakage is prevented. According to different application ranges, the method mainly comprises the following steps: linear staplers, circular staplers, linear cutting staplers, purse string staplers, endoscopic specialized staplers, and the like. The existing anastomosis nails of the existing disposable circular or anorectal anastomat are titanium nail anastomosis, and a plurality of suturing nails are needed to participate in one-time suturing. There is no correlation between the suturing nails, the structural strength is poor, and the space utilization rate is low. When the titanium nail structure is used for treating the condition of thick tissue, the untight suture is easy to be generated due to the uneven tissue thickness, and then bleeding and suture failure occur.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: the utility model provides a circular anastomose ring, includes anastomose ring body 1, anastomose ring body 1 is from up following and is divided into in proper order sews up nail 2, lower rubber ring 3 and go up rubber ring 4, sew up nail 2 and be provided with a plurality of shell fragments 8 down between the rubber ring 3, sew up nail 2 and include

support ring

5, 5 tops of support ring are provided with a plurality of spikes 6, spike 6 encircles the centre of a circle evenly distributed of support ring 5.

The top end of the spike 6 is provided with a spike 7, the spike 7 is in a shape of which the width is gradually reduced from bottom to top, and the width of the bottom end of the spike is larger than that of the spike 6.

The elastic sheet 8 is a long-strip-shaped arc-shaped metal sheet, the elastic sheet 8 is arranged at the top end of the support ring 5, and two ends of the elastic sheet are in contact with the support ring 5.

The surface of the elastic sheet 8 is provided with a limiting groove corresponding to the suturing nail 2, and the upper end face of the support ring 5 is provided with a positioning groove corresponding to the elastic sheet 8.

The surface of the lower rubber ring 3 is provided with a plurality of through grooves 9 which are in one-to-one correspondence with the suturing nails 2.

Through groove 9 and sew up for transition fit between the nail 2, the top of shell fragment 8 contacts the setting with rubber ring 3 down.

The lower end face of the upper rubber ring 4 is provided with a plurality of grooves 10 which correspond to the suturing nails 2 one by one.
