According to the latest cancer statistical survey in 2015 China, the prostate cancer is one of 6 cancers with high incidence rate of male cancers in China, and is located at the 9 th site of ten major malignant tumors in human and the 6 th site of the male malignant tumors. Along with the improvement of living standard, the incidence of the prostate cancer is gradually increased, and the number of newly increased patients with the prostate cancer in China is 6.03 ten thousands of people according to the measurement and calculation in 2015, wherein the incidence of urban men is about 3.7 times that of rural areas. Its incidence in urology has currently prevailed over bladder cancer. Radical prostatectomy is an effective means for treating prostate cancer, and open and laparoscopic surgeries have been widely performed clinically. The key to the operation is to re-engage the urethra with the bladder after removal of the prostate. At present, although a small amount of anastomats are available, the clinical application effect is not ideal due to the narrow operation operable area. Suturing with needle and thread is still the mainstream of open and laparoscopic urethral and bladder anastomosis. The tension of the anastomotic stoma directly determines the success or failure of the surgical suture and the recovery of the postoperative urinary control of the patient. Two methods are currently used in clinical practice. On one hand, the broken end of the urethra of the patient can be exposed and simultaneously close to the bladder by the pushing of the perineum of the patient by the assistant under the table, and on the other hand, the bladder can be pushed to close to the urethra by the grasping forceps and the like in the hand of the assistant on the table. The suturing process also needs to complete the anastomosis operation by means of the guidance of the urethral probe and the ureter. On one hand, a large amount of manpower is wasted, the tension reducing effect is limited, and on the other hand, in the later anastomosis process, the connection suture between the urethral canal and the balloon fracture is easily caused due to the soft rubber material of the urethral canal. This brings great risks to the development of clinical surgery and to the prognosis of the patient.

Meanwhile, the urine control function of the patient can be recovered more quickly and better. Post-operative often it is also necessary to perform internal stoma relaxation, which is mainly achieved by pulling the ureter. Usually medical personnel can slight tractive ureter and fix the head on skin, and patient's postoperative drainage volume is more for the first day sometimes, and medical personnel avoid the ureter damage simultaneously for reinforcing tractive effect, can be in the glans penis department of patient and tie the every day change of gauze, prevent to drop or the patient activity leads to the tractive force to weaken because of the adhesive tape. On the one hand, great inconvenience is brought to the clinical nursing staff for changing the medicine, and meanwhile, discomfort symptoms of partial patients are caused.

In order to solve the problem clinically, a bladder-urethra anastomosis tension reducing kit is designed, so that the accuracy and the efficiency of surgical anastomosis are guaranteed, and meanwhile, the postoperative recovery of a patient is guaranteed.
