Embodiment Construction
[0044] Laparoscopic radical prostatectomy is the main method for the treatment of early and mid-stage prostate cancer, but laparoscopic surgery has high technical requirements for the surgeon, especially the anastomosis of the bladder and urethra after prostatectomy has always been the focus and difficulty of laparoscopic prostate cancer surgery , requires the operator to have rich experience and surgical skills, if the anastomosis is not good, there may be risks of urinary leakage and long-term urinary incontinence after surgery.
[0045] The laparoscopic vesicourethral stapler proposed in the embodiment of the present invention can well solve the problem of vesicourethral anastomosis, greatly reducing the difficulty and risk of surgery. It is generally divided into one-time or multiple use, and is used to replace traditional manual suturing. It is easy to use, tight, and suitable for tightness, especially its fast suturing, easy operation, and few side effects and surgical co...

The invention provides an anastomat. The anastomat comprises a nail abutting seat rod, wherein a nail abutting seat is arranged at the head of the nail abutting seat rod. An anastomat body comprises anastomater rod, a nail bin assembly, a knob adjuster, a fixed handle and a percussion handle, wherein the nail bin assembly is arranged at the head of the anastomat rod; the knob adjuster is arrangedat the position, close to the tail, of the anastomat rod and used for adjusting the rotating angle of the anastomat rod so that the nail abutting seat can be conveniently folded; the fixed handle is arranged at the tail of the anastomat rod and used for holding the anastomat rod; and the percussion handle is used for percussion in an anastomotic mode and arranged between the knob adjuster and thefixed handle.
Description
technical field [0001] The invention belongs to minimally invasive surgical instruments, in particular to a bladder-urethra stapler which can be used under laparoscopy. Background technique [0002] Prostate cancer (PCa) is a common malignant tumor of the male urinary system, and its incidence increases with age. In 2016, prostate cancer ranked first in male cancer incidence and third in fatality worldwide, and is a malignant tumor that seriously endangers male health. In China, in recent years, with the changes in diet and living habits, and the popularization of prostate specific antigen (PSA) screening, the incidence of prostate cancer has shown a continuous and rapid growth trend, with 60,300 cases in 2015, With 26,600 deaths, it has become the malignant tumor with the highest morbidity and mortality in male genitourinary system in China. [0003] At present, laparoscopic radical prostatectomy is the main method for the treatment of early and mid-stage prostate cancer....
