Background

Bladder cancer is one of the most common clinical tumors in urology surgery in China, is a disease which directly threatens the survival of patients, the incidence rate of the disease is in a year-by-year increasing trend, and radical cystectomy is the standard treatment of recurrent, multiple and invasive bladder cancer; radical prostatectomy is one of the most effective methods for curing localized prostate cancer, and the key and difficult points of the operation are the key technical problems of reconstruction of the lower urinary tract, namely bladder-urethra anastomosis. At present, a manual suturing method is mostly adopted, but because the anastomotic stoma is positioned at the bottom of the pelvis, the position is deep, the operation space is narrow, the suturing technology difficulty is high, the operation time is long, the anastomosis effect is difficult to ensure, and a series of complications such as urinary fistula or anastomotic stoma stenosis easily occur.

Along with the development of anastomosis technology, a suture anastomosis method and a mechanical nail ring anastomosis method are gradually developed, wherein the suture anastomosis method for performing butt joint suturing on the broken ends of the bladder and the urethra by utilizing a suture is a currently accepted blood vessel anastomosis standard method and is also a blood vessel anastomosis method which is most commonly used clinically before the day; the mechanical nail ring anastomosis method is to penetrate and evert and fix the broken ends of two bladders and urethra on independent anastomotic rings respectively, and the anastomosis of the broken ends of the bladders and the urethra is realized by means of the close pairing of the anastomotic rings.

For example, a microvascular anastomat disclosed in chinese patent publication No. CN202875417U, which comprises an anastomotic clip comprising a combination clamp, two needle ring holding clamps, two needle rings, a torsion spring and a connecting pin; the needle ring is arranged on the needle ring holding forceps in a matching and detachable manner; the front end face of the combined clamp is provided with a pin hole for fixedly installing a connecting pin rod, and the rear end of the combined clamp is provided with an inserting rod extending outwards along the axial direction of the combined clamp; the needle surrounding clamp and the torsion spring are fixedly assembled on the front end face of the combined clamp through a connecting pin rod; the two torsion bars of the torsion spring are respectively arranged on the inner side surfaces of the two needle encircling pliers. The utility model has simple structure, simple and convenient operation, good vascular anastomosis effect and easy grasp, and a doctor can master the operation of the microvascular anastomat skillfully after a period of several weeks, and can obtain good anastomosis effect; in practical application, the time for anastomosis of blood vessels can be reduced to the greatest extent.

Although the device realizes anastomosis operation on the micro blood vessels and reduces the time for anastomosis of the blood vessels, in the actual operation process, in order to facilitate the ejection of the two needle rings in an extrusion mode to separate the needle rings from the needle ring holding forceps, one ends of the two needle rings, which are far away from the inserted bars, are not limited, so that the two needle rings possibly deviate due to improper operation of medical staff in the operation process, and are separated from the needle ring holding forceps even in severe cases, the separated needle ring tips scratch the surfaces of tissues in a human body and increase the operation risk.
